The Case

A 41-year-old woman sits upright after a fall from a ladder, pressing gauze beneath her nose as blood beads over her upper lip. Her two front teeth no longer meet, and she says the room “moves” when she looks toward the ceiling. Clear fluid intermittently drips from one nostril, but she is speaking in full sentences and insists she feels fine. The question is what to secure before the next examination.

Before You Read

Which findings distinguish a stable facial fracture from a threatened midface?
What does malocclusion tell you?
When is a nasal route unsafe?

Why It Matters

Midfacial fractures can destabilize the airway, orbit, skull base, and dental occlusion simultaneously. CSF leak, ocular entrapment, and retrobulbar pressure are time-sensitive complications that may be missed beneath epistaxis and swelling.

When to Think of It

Suspect midfacial fracture with malocclusion, mobile maxilla, midface flattening or elongation, epistaxis, facial numbness in V2 distribution, diplopia, telecanthus, nasal deformity, CSF rhinorrhea, or high-energy mechanism.

Sick or Not Sick

The decisive fork is stable airway and vision versus any airway compromise, globe-threatening finding, or uncontrolled hemorrhage. Proptosis, tense orbit, vision loss, afferent pupillary defect, severe hypoxia, expanding oral swelling, or uncontrolled bleeding requires immediate specialty-directed intervention.

The First Fifteen Minutes

Any active facial bleeding or airway contamination: sit the patient forward if spinal injury is excluded, suction continuously, use 100% oxygen at 15 L/min for hypoxemia, and maintain cervical precautions when indicated; positioning and suction prevent blood aspiration.
Hemodynamic instability from traumatic hemorrhage: activate the trauma hemorrhage pathway and give tranexamic acid 1 g IV over 10 minutes, then 1 g IV over 8 hours when within 3 hours and consistent with local protocol; it limits fibrinolysis.
Open fracture, gross contamination, or operative midface fracture: give ampicillin-sulbactam 3 g IV as initial prophylaxis/therapy; it covers oral and sinus flora. Antibiotic choice and duration vary by injury and institutional protocol; closed, uncomplicated fractures do not automatically require antibiotics.
Severe pain with adequate ventilation: give fentanyl 25–50 mcg IV, titrated every 5 minutes; it provides rapid analgesia but can suppress breathing.
Suspected globe-threatening orbital compartment syndrome: immediately call ophthalmology and perform urgent lateral canthotomy/cantholysis when indicated; do not delay for CT. If systemic analgesia is required, use fentanyl 25–50 mcg IV while definitive decompression is arranged.
Incomplete or unknown tetanus vaccination with contaminated wound: give Tdap/Td 0.5 mL IM; add tetanus immune globulin 250 IU IM for a dirty wound when the primary series is incomplete or unknown.

Definitive Care & Disposition

CT maxillofacial bones with thin cuts is the principal imaging study; add CT head for neurologic symptoms or significant mechanism and CTA for suspected vascular injury. Avoid blind nasal instrumentation when skull-base or cribriform injury is possible. Admit patients with airway risk, CSF leak, ocular injury, open or unstable fractures, uncontrolled bleeding, inability to maintain hydration, or unreliable follow-up. Definitive management may include reduction and fixation, endoscopic repair of CSF leak, dental stabilization, orbital decompression, and management by trauma, ENT/facial plastics, ophthalmology, and oral-maxillofacial surgery.

How This One Kills

The dangerous miss is interpreting clear unilateral rhinorrhea as simple mucus and placing a nasogastric or nasotracheal tube through a fractured skull base.

The Atypical Presentation

Midfacial injury may be subtle in a patient with edema, dentures, intoxication, or preexisting malocclusion. A patient may deny diplopia because swelling limits testing, or describe only “a strange bite” and facial numbness. Compare the patient’s habitual occlusion, inspect for maxillary mobility while supporting the skull, test each eye separately, assess V2 sensation, and ask specifically about clear rhinorrhea and swallowing blood.

Back to Our Patient

Back to the 41-year-old woman: malocclusion, vertigo with gaze, and clear unilateral rhinorrhea after a fall make midfacial and skull-base injury more likely than an isolated nasal fracture. She is currently stable, so the team protects the cervical spine, avoids nasal instrumentation, suctions blood, performs a careful ocular and neurologic examination, and obtains CT head and maxillofacial imaging. Imaging shows a Le Fort II fracture with a suspected skull-base extension but no globe compartment syndrome; ENT, facial surgery, ophthalmology, and trauma admit her for operative planning and observation for CSF leak and airway deterioration.

Patient Presentation to Attending

“This is a 41-year-old woman after a ladder fall with epistaxis, new malocclusion, intermittent clear unilateral rhinorrhea, and diplopia on upward gaze. She is speaking comfortably with stable oxygenation, but the maxilla feels mobile, and she has decreased sensation in the infraorbital distribution; pupils are symmetric without obvious proptosis. My concern is an unstable midface fracture with possible orbital involvement and skull-base injury. I recommend cervical precautions, suction, avoidance of nasal instrumentation, CT head and maxillofacial imaging, and early ENT/facial-surgery and ophthalmology consultation. She should be admitted because of the unstable fracture pattern and potential CSF leak.”

Study Directive

Draw the three Le Fort fracture levels and list one bedside finding for each.
Review five facial CTs and identify the maxillary buttresses and pterygoid plate involvement.
Practice a focused midface examination: occlusion, mobility, V2 sensation, ocular function, and CSF-leak questions.
Memorize the indications for urgent ophthalmology involvement and write them into your trauma note template.

Key Medications

Tranexamic acid 1 g IV over 10 min, then 1 g over 8 h for significant traumatic hemorrhage within 3 hours; verify local trauma protocol.
Ampicillin-sulbactam 3 g IV for selected open/contaminated facial fractures; dosing and duration vary—check institutional protocol or Lexicomp.
Fentanyl 25–50 mcg IV, titrated.
Tdap/Td 0.5 mL IM; tetanus immune globulin 250 IU IM when indicated.
Pediatric antibiotic, analgesic, and TXA doses are weight-based; use a pediatric reference.

High-Yield Pearls

Malocclusion is a functional marker of facial skeletal instability, not merely a dental complaint.
Clear rhinorrhea after midface trauma is a skull-base warning until proven otherwise; avoid blind nasal tubes.
A patient with diplopia needs visual acuity, pupils, color vision when possible, and ocular motility—not just a CT report.

The Mimics

Simple nasal fracture — stable occlusion and no midface mobility; misclassification delays evaluation of Le Fort or skull-base injury.
Orbital blowout fracture — isolated diplopia with preserved facial support; treating it as a broader midface fracture may miss the specific need to assess entrapment.
CSF rhinorrhea from basilar skull fracture — clear drainage worsened by leaning forward; missing it risks meningitis and unsafe nasal instrumentation.
Dental avulsion — tooth displacement without mobile maxilla; focusing only on the tooth can miss unstable facial architecture.

Board Question

Which finding most strongly suggests a Le Fort fracture rather than an isolated nasal fracture?

APeriorbital ecchymosis
BEpistaxis
CMalocclusion with mobility of the maxilla
DNasal tenderness

Reveal answer

Correct: C

Le Fort fractures disrupt the maxillary buttresses and produce abnormal dental occlusion and segmental mobility. Epistaxis and periorbital ecchymosis can occur with many facial injuries and are not specific.

NASAL TRAUMA

Most nasal fractures are minor, but a missed septal hematoma can destroy cartilage and cause saddle-nose deformity or abscess. The exam—not routine...

0:00 / –:–– AI‑generated audio

The Case

A 19-year-old basketball player arrives holding an ice pack against a nose that bends slightly to the left. His jersey is spotted with dried blood, and he says one side has become harder to breathe since the collision. He has no loss of consciousness and can see normally, but a soft, dark swelling fills both anterior nasal passages. The decision is whether this is a cosmetic injury or a clock already running.

Before You Read

What must be identified before sending an apparently stable nasal injury home?
When is imaging unnecessary?
How do you distinguish a septal hematoma from ordinary swelling?

Why It Matters

Most nasal fractures are minor, but a missed septal hematoma can destroy cartilage and cause saddle-nose deformity or abscess. The exam—not routine radiography—determines urgency.

When to Think of It

Look for deformity, epistaxis, obstruction, septal deviation, septal swelling, nasal bone mobility or crepitus, facial numbness, malocclusion, ocular symptoms, and signs of skull-base injury.

Sick or Not Sick

The key call is whether a septal hematoma, uncontrolled hemorrhage, open/complex fracture, or associated facial injury is present. A septal hematoma is urgent even when the external deformity looks small.

The First Fifteen Minutes

Active epistaxis without airway compromise: sit forward and apply firm continuous compression to the soft nasal alae for 10–15 minutes; direct pressure collapses the bleeding vessels.
Ongoing anterior bleeding: apply oxymetazoline 0.05%, 2 sprays into the affected nostril, then repeat direct pressure; alpha-adrenergic vasoconstriction reduces mucosal blood flow. Avoid or use cautiously in severe uncontrolled hypertension or significant ischemic disease.
Need for painful inspection or packing: apply lidocaine 4% topical, up to 200 mg total in adults, often combined locally with oxymetazoline; it blocks mucosal pain and facilitates examination. Maximum dosing varies by formulation and patient factors—check a reference.
Septal hematoma: perform immediate drainage by ENT, facial surgery, or trained emergency clinician with local anesthesia; lidocaine 1% with epinephrine 1:100,000, infiltrated locally, is commonly used, staying within a total lidocaine dose of 7 mg/kg with epinephrine. Drainage prevents cartilage necrosis; do not delay for plain films.
Contaminated laceration with incomplete/unknown tetanus vaccination: give Tdap/Td 0.5 mL IM; add tetanus immune globulin 250 IU IM for a dirty wound with incomplete or unknown primary series.

Definitive Care & Disposition

Drain and pack septal hematomas and arrange urgent ENT follow-up, often within 24–48 hours. Obtain CT maxillofacial imaging when there is suspected complex fracture, orbital involvement, malocclusion, neurologic injury, CSF rhinorrhea, or unreliable examination; plain nasal radiographs rarely change management. Delay elective closed reduction until swelling decreases, commonly 3–7 days, while arranging specialty review; reduction is generally performed within about 10–14 days in adults, with timing varying by patient and service. Discharge uncomplicated injuries only after bleeding is controlled, no septal hematoma exists, vision and occlusion are normal, and follow-up is reliable.

How This One Kills

The classic failure is documenting “nasal fracture” without lifting the nasal tip and inspecting/palpating the septum, allowing a septal hematoma to progress to cartilage necrosis and saddle-nose deformity.

The Atypical Presentation

Older adults, anticoagulated patients, and children may have little deformity despite substantial bleeding or septal injury. In children, nasal obstruction or persistent mouth breathing may be the only clue, and cartilage injury can affect later growth. Reassess after clot removal and topical vasoconstriction; inspect the entire septum, compare airflow, and ask about preinjury shape and breathing.

Back to Our Patient

Back to the 19-year-old basketball player: the bilateral dark, fluctuant septal swelling is a septal hematoma, not ordinary post-traumatic edema. He is otherwise stable, so the team controls bleeding with forward positioning, pressure, oxymetazoline, and topical anesthetic, then arranges immediate drainage and packing. He is discharged only after drainage, tetanus review, pain instructions, and urgent ENT follow-up for reassessment and possible delayed reduction of the external nasal deformity.

Patient Presentation to Attending

“This is a 19-year-old man after a basketball collision with external nasal deviation, persistent obstruction, and a bilateral boggy septal swelling. He has no loss of consciousness, vision change, malocclusion, neurologic deficit, or clear rhinorrhea. Bleeding is limited to the anterior nose, and his vital signs are stable. My concern is a traumatic septal hematoma with an associated nasal fracture, which requires urgent drainage to prevent cartilage necrosis. I recommend topical oxymetazoline and lidocaine, immediate drainage and packing, tetanus assessment, and ENT follow-up; CT is not needed unless additional midface or skull-base findings emerge.”

Study Directive

Examine three nasal-trauma patients or simulation cases and explicitly document septal appearance, airway patency, occlusion, ocular findings, and CSF-leak symptoms.
Memorize oxymetazoline and lidocaine maximum doses, then verify the formulations stocked in your department.
Review when CT changes management and when it is unnecessary.
Practice explaining to a patient why an apparently small septal swelling requires same-day drainage.

Key Medications

Oxymetazoline 0.05%, 2 sprays intranasally, may repeat once after pressure; avoid prolonged use beyond 3 days.
Lidocaine 4% topical: maximum commonly 200 mg in adults; verify product-specific maximum.
Lidocaine 1% with epinephrine 1:100,000: maximum commonly 7 mg/kg, not exceeding the product/institutional maximum; check a dosing reference.
Tdap/Td 0.5 mL IM; tetanus immune globulin 250 IU IM when indicated.
Pediatric topical anesthetic and vasoconstrictor limits differ; use pediatric dosing guidance.

High-Yield Pearls

A septal hematoma is a physical-examination diagnosis; normal nasal radiographs do not exclude it.
Never cauterize both sides of the septum simultaneously because bilateral mucosal injury increases perforation risk.
Nasal bone deformity can wait for swelling to improve; septal hematoma cannot.

The Mimics

Septal hematoma — fluctuant, boggy, often bilateral septal swelling that does not shrink with vasoconstrictor; confusing it with edema causes permanent deformity.
Septal abscess — fever, worsening pain, purulence, and systemic symptoms; mistaking it for hematoma delays drainage and antibiotics.
CSF rhinorrhea — clear unilateral drainage after significant trauma, sometimes positional; missing it risks meningitis and unsafe nasal instrumentation.
Nasal vestibular furuncle — focal pustule and localized tenderness without traumatic deformity; unnecessary fracture reduction misses an infectious source.

Board Question

A patient with nasal trauma has bilateral, fluctuant septal swelling and nasal obstruction. What is the most appropriate management?

AReassurance and discharge
BOral antihistamine and intranasal steroid
CImmediate drainage and packing
DRoutine nasal radiographs followed by outpatient review

Reveal answer

Correct: C

A septal hematoma requires urgent drainage because pressure compromises septal cartilage blood supply and can lead to abscess or saddle-nose deformity. Imaging should not delay treatment.

TOPICAL HEMOSTATICS

Topical hemostatics are adjuncts, not replacements for pressure, packing, ligation, repair, or operative control. Used correctly they buy time; used blindly...

0:00 / –:–– AI‑generated audio

The Case

A 67-year-old woman arrives with a towel pressed to a jagged scalp laceration after falling onto a broken cabinet. The towel is warm and saturated, and bright blood has begun tracking down her neck. She takes apixaban for atrial fibrillation, is pale but talking, and the wound edges gape whenever the pressure slips. The next question is whether a packet of gauze is enough.

Before You Read

When does a topical hemostatic help, and when is it a dangerous substitute for control?
Which products belong in a deep cavity, and which require removal?
What must happen before topical hemostatic material is applied?

Why It Matters

Topical hemostatics are adjuncts, not replacements for pressure, packing, ligation, repair, or operative control. Used correctly they buy time; used blindly they conceal ongoing hemorrhage, cause tissue injury, or delay definitive care.

When to Think of It

Consider a topical agent for persistent low- to moderate-volume bleeding from a compressible wound, junctional area, mucosal surface, dental socket, or operative field after direct pressure and exposure have been attempted.

Sick or Not Sick

The critical decision is compressible oozing versus uncontrolled arterial or cavitary hemorrhage. Spurting blood, hemodynamic instability, expanding hematoma, hard vascular signs, or bleeding that cannot be visualized requires packing, proximal control, transfusion, and procedural or operative intervention—not topical powder alone.

The First Fifteen Minutes

Any external bleeding: expose the wound and apply firm direct pressure with plain gauze for at least 10 uninterrupted minutes; compression collapses the vessel and permits platelet-fibrin plug formation.
Persistent bleeding from a compressible wound after adequate pressure: apply a kaolin- or chitosan-impregnated gauze directly into the wound and maintain firm pressure for at least 3 minutes, following the product instructions; kaolin activates factor XII and chitosan promotes clot formation and tissue adherence. Remove gross clot and identify the bleeding surface first.
Deep junctional or cavity wound that cannot be compressed externally: tightly pack with hemostatic gauze, then maintain pressure for at least 3 minutes; packing creates tamponade while the agent supports clot formation. Do not pack the orbit, airway, or intracranial space unless directed by a specialist.
Nasal mucosal bleeding after pressure: apply oxymetazoline 0.05%, 2 sprays intranasally, then pressure; vasoconstriction reduces mucosal inflow. Persistent bleeding requires appropriate anterior or posterior packing and ENT involvement.
Bleeding dental socket: place oxidized cellulose or absorbable gelatin sponge in the socket and bite firmly on gauze for 20–30 minutes; the matrix supports local clot formation. Avoid placing loose material where aspiration is possible.
Bleeding with shock or major traumatic blood loss: give tranexamic acid 1 g IV over 10 minutes, followed by 1 g IV over 8 hours when within 3 hours and following local trauma protocol; it inhibits fibrinolysis systemically but does not replace mechanical control.
Dirty wound with incomplete/unknown tetanus vaccination: give Tdap/Td 0.5 mL IM; add tetanus immune globulin 250 IU IM when indicated.

Definitive Care & Disposition

Irrigate and explore once bleeding is controlled; remove nonabsorbable agents when the manufacturer recommends it, and debride or repair the wound as needed. Use absorbable gelatin, oxidized regenerated cellulose, or fibrin sealant selectively in appropriate tissue planes; avoid oxidized cellulose in confined spaces where swelling or mass effect matters and avoid products containing thrombin in patients with relevant sensitivities. Persistent bleeding may require vessel ligation, electrocautery, balloon tamponade, interventional radiology, reversal of anticoagulation, or surgery. Admit patients with ongoing hemorrhage, transfusion need, deep facial/neck wounds, anticoagulant-associated uncontrolled bleeding, posterior epistaxis, or unreliable hemostasis; discharge only after stable observation and explicit wound follow-up.

How This One Kills

The dangerous mistake is placing hemostatic material over an unrecognized arterial injury and declaring hemostasis while blood continues accumulating in a deep space or the patient progresses to shock.

The Atypical Presentation

Patients taking anticoagulants, with thrombocytopenia, liver disease, or uremia may have deceptively small wounds with persistent seepage rather than dramatic spurting. A partially saturated dressing does not quantify blood loss, and normal initial blood pressure may reflect early compensation. Trend vital signs, mental status, skin perfusion, wound size, and hemoglobin when clinically indicated; ask specifically about anticoagulant timing and last dose.

Back to Our Patient

Back to the 67-year-old woman: after exposure, the scalp wound continues to ooze despite ten minutes of direct pressure, but there is no pulsatile jet, expanding neck hematoma, or shock. The team applies hemostatic gauze directly into the wound with sustained pressure while obtaining IV access, checking anticoagulant timing, and preparing blood if her perfusion worsens. Bleeding stops, the wound is irrigated and repaired, and because she is anticoagulated with a deep contaminated laceration requiring observation, she is admitted for serial examinations and individualized anticoagulant management rather than discharged after simply covering the wound.

Patient Presentation to Attending

“This is a 67-year-old woman on apixaban with a deep contaminated scalp laceration after a fall and persistent oozing despite ten minutes of direct pressure. She is pale but alert and currently hemodynamically stable, with no pulsatile bleeding, expanding neck hematoma, focal neurologic deficit, or airway issue. The wound is fully exposed and gaping, with bleeding localized to the soft-tissue bed. My assessment is anticoagulant-associated compressible hemorrhage without current hard signs of arterial injury. I recommend hemostatic gauze with sustained pressure, two IVs and serial perfusion checks, CBC and type-and-screen, tetanus assessment, irrigation and repair after control, and admission for observation and anticoagulant-reversal consultation if bleeding recurs.”

Study Directive

Handle every topical hemostatic product stocked in your department and learn its pressure time, removal instructions, and contraindications.
Practice a wound-control sequence: expose, direct pressure, pack if deep, apply adjunct, reassess perfusion and bleeding.
Review your institution’s reversal pathways for apixaban, rivaroxaban, dabigatran, warfarin, and heparin.
Simulate a patient whose “controlled” wound continues to bleed and verbalize the escalation to transfusion, procedural control, IR, or surgery.

---

Key Medications

Tranexamic acid 1 g IV over 10 min, then 1 g over 8 h for significant traumatic hemorrhage within 3 hours; verify local protocol.
Oxymetazoline 0.05%, 2 sprays intranasally for anterior epistaxis; avoid prolonged use.
Tdap/Td 0.5 mL IM; tetanus immune globulin 250 IU IM when indicated.
Anticoagulant reversal is agent- and severity-specific: consult the institutional reversal protocol, Lexicomp, or UpToDate before dosing and balance thrombosis risk.
Pediatric topical-agent use and TXA dosing are weight-based; use pediatric trauma guidance.

High-Yield Pearls

“Hemostatic” does not mean “definitive”: persistent bleeding after correct application demands reassessment for arterial injury or coagulopathy.
Packing creates tamponade; the topical agent augments clot formation—the combination is often more effective than powder alone.
Always document what product was used, where it was placed, and whether it must be removed.

The Mimics

Arterial hemorrhage — pulsatile, rapidly refilling bleeding; topical material alone delays ligation or embolization.
Venous oozing — diffuse slow bleeding that responds to sustained pressure; unnecessary aggressive agents add cost and foreign material without solving the problem.
Compartment or concealed hemorrhage — enlarging swelling with little external blood; focusing on the surface misses ongoing internal blood loss.
Coagulopathy — persistent bleeding from multiple sites; local hemostatic treatment without systemic correction fails.

Board Question

Which is the best initial use of a topical hemostatic dressing for a traumatic wound?

AApply it immediately without exposing the wound
BPlace it over a wound with uncontrolled pulsatile arterial bleeding and no pressure
CApply it after adequate direct pressure for persistent compressible bleeding
DInsert it into the orbit to control retrobulbar hemorrhage

Reveal answer

Correct: C

Topical hemostatics work best as adjuncts after exposure and direct pressure, particularly for persistent compressible bleeding. They are not substitutes for arterial control and should not be placed in dangerous confined spaces such as the orbit.

Tongue Blade Test for Mandibular Fracture

Use the tongue blade test only as a low-risk adjunct; a negative result does not exclude mandibular fracture.

0:00 / –:–– AI‑generated audio

Learning Objective

Use the tongue blade test only as a low-risk adjunct; a negative result does not exclude mandibular fracture.

Steps

Explain the maneuver and have the patient bite firmly on a wooden tongue depressor.
Ask the patient to maintain the bite while attempting to twist or pull the blade away.
A positive test is inability to maintain the bite because of pain or fracture-related instability.
Examine for malocclusion, trismus, intraoral laceration, dental injury, numbness, and step-off; obtain CT when clinical suspicion remains.

Retrieval Prompt

Does a negative tongue blade test rule out mandibular fracture? → No; persistent clinical suspicion requires appropriate imaging, usually maxillofacial CT.
