SIGNS AND SYMPTOMS
  • Nasal deformity, asymmetry, swelling, or ecchymosis
  • Epistaxis
  • Periorbital ecchymosis (“raccoon eyes”) from damage to branches of ethmoidal artery:
    • May indicate nasofrontoethmoid complex injury
  • Palpable sharp edges, depressions, or other irregularities suggest nasal fracture.
  • Crepitus or mobility of skeletal parts on palpation
  • Septal hematoma:
    • Bluish fluid-filled sac overlying nasal septum
    • Critical to detect because it must be drained
    • Failure to drain can result in necrosis of the septum
  • Flattening of nasal root and widening of intercanthal distance (telecanthus):
    • Indicative of serious nasofrontoethmoid complex injury
  • Clear rhinorrhea indicates possible CSF leak:
    • Rhinorrhea may be delayed.
  • Loss of sense of smell suggests significant injury.
  • Tear duct injuries may be present with abnormal tearing.
  • Associated eye injuries:
    • Subconjunctival hemorrhage
    • Hyphema
    • Retinal detachments
History
  • Direct blow
  • Associated injuries or symptoms
  • Presence of epistaxis
  • Changes in vision or smell
Physical-Exam
  • Thorough physical exam with visual inspection and palpation is vital.
  • It is critical to identify a septal hematoma:
    • Bluish bulging mass on nasal septum
  • Septal deviation
  • Epistaxis or intranasal laceration
  • Examine closely for telecanthus:
    • Intercanthal width >30–35 mm
    • Wider than width of 1 eye
    • May indicate nasofrontoethmoid fracture
    • Usually associated with depressed nasal bridge
  • CSF rhinorrhea:
    • Indicates more serious underlying facial bone or skull fracture
    • CSF mixed with blood will often cause double ring sign when placed on filter paper, although this sign is not 100% reliable.
ESSENTIAL WORKUP

If concern for anything other than a simple nasal fracture:

  • Evaluate nasolacrimal duct for patency:
    • Instill fluorescein into eye and look for it in nasopharynx under inferior turbinate.
    • Absence implies duct injury.
  • Eyelash traction test:
    • Grasp eyelashes on eyelid and pull laterally:
    • If eyelid margin does not become taut or “bow string,” then medial portion of tendon has been disrupted.
    • This test is performed on both upper and lower eyelids.
      • Possible for only 1 portion of tendon to be selectively injured
DIAGNOSIS TESTS & NTERPRETATION
Lab

Coagulation studies if on anticoagulants with uncontrolled epistaxis

Imaging
  • Nasal radiographs are rarely indicated:
    • Normally do not alter initial or subsequent management
    • Gross deformities will need referral.
    • Fractures without deformity will be treated conservatively regardless of radiographic findings.
    • Patients with associated facial bone deformity, crepitus, or tenderness may require radiographs.
  • CT is test of choice if facial bone, nasofrontoethmoid, or depressed skull fractures are suspected; have low threshold for ordering CT if other injuries are suspected.
DIFFERENTIAL DIAGNOSIS
  • Other facial injuries such as orbital, frontal sinus, maxillary sinus, or cribriform plate fractures
  • Nasofrontoethmoid fracture
TREATMENT
PRE HOSPITAL
  • Management of airway takes precedence.
  • Nasotracheal intubation is contraindicated.
  • Consider orotracheal intubation or cricothyroidotomy if definitive airway control is needed.
  • Cervical spine precautions are indicated if there is associated trauma.
  • Epistaxis can normally be controlled with direct pressure; pinch nares together.
INITIAL STABILIZATION/THERAPY
  • Airway management with orotracheal intubation or cricothyroidotomy:
    • Nasotracheal intubation is contraindicated.
  • Cervical spine precautions
  • Other injuries take precedence.
ED TREATMENT/PROCEDURES
  • Abrasions and lacerations:
    • Proper cleansing of facial wounds is essential.
    • Lacerations may be sutured.
  • Epistaxis must be controlled if it does not stop spontaneously:
    • Anesthetize/vasoconstrict with topical cocaine, lidocaine, or neosynephrine spray.
    • Identify bleeding source; cauterize anterior source if necessary.
    • Pack nares with petroleum jelly, impregnated gauze, or any number of commercial packs.
    • Posterior packs are rarely needed.
    • Prophylactic antibiotics to prevent sinus infection are indicated if packed: Amoxicillin, amoxicillin/clavulanate, or trimethoprim–sulfamethoxazole or azithromycin in penicillin allergic patients.
    • Displaced fractures do not need reduction in ED unless airway is compromised.
    • Generally recommended to allow swelling to abate and reduce fracture in 3–5 days, although there are many specialists who recommend local anesthesia and immediate reduction.
  • Septal hematoma must be drained immediately in ED:
    • Anesthetize with topical cocaine or lidocaine and vascular constriction with neosynephrine.
    • Attempt to aspirate with 18G to 20G needle on 3-mL syringe.
    • Rolling cotton swab down septum may facilitate drainage.
    • Holding mucosa down against cartilage must be done to prevent reaccumulation.
    • This can be done with petroleum jelly gauze packing.
    • Both nares should be packed to ensure adequate pressure:
      • Packing is left in place for 3–5 days or until follow-up with ear, nose, and throat (ENT).
    • Prophylactic antibiotics are prescribed.
MEDICATION
  • Amoxicillin: 500 mg PO TID (peds: 40 mg/kg PO div. TID)
  • Amoxicillin/clavulanate: 500/125–875/125 mg PO BID (peds: 40 mg/kg/d of amoxicillin PO BID)
  • Azithromycin: 500 mg PO day 1 followed by 250 mg PO daily for 4 additional days (peds: 10 mg/kg PO day 1, followed by 5 mg/kg PO days 2–4)
  • Cocaine: Topical 4%
  • Lidocaine: 1–2% without epinephrine
  • Neosynephrine nasal spray
  • Trimethoprim–sulfamethoxazole: Double strength (DS) PO BID (peds: 40 mg/kg/d sulfamethoxazole PO BID)
IN PATIENT CONSIDERATIONS
Admission Criteria
  • Most nasal fractures do not require admission.
  • Admit patients with nasoethmoid fractures or more significant craniofacial injuries.
Discharge Criteria
  • No evidence of significant head, neck, or other injuries.
  • Epistaxis controlled
  • Reliable companion or caregiver
Pediatric Considerations
  • Follow up with specialist sooner because fibrous union begins in only 3–4 days
  • Consider contacting child protective services if any suspicion of nonaccidental trauma:
    • History does not fit injury.
    • Always consider nonaccidental trauma as potential mechanism of injury.
  • Fractures are rare in children; nasal injuries in children are more likely to be cartilaginous.
  • Significant injuries in children are not always fully appreciated.
FOLLOW-UP
FOLLOW-UP RECOMMENDATIONS
  • Follow up with ENT, plastic surgery, or oral maxillofacial (OMF) surgeon in 3–5 days for management:
    • Patients with septal hematoma should follow up in 24 hr for re-evaluation after drainage.
  • Return for signs of clear rhinorrhea, difficulty breathing, fever, or signs associated with head injury.
PEARLS AND PITFALLS
  • The absence of a septal hematoma must be documented in every case.
  • Every patient discharged with nasal packing should be placed on antistaphylococcal antibiotics.
  • Consider cribriform plate fractures in patients with clear rhinorrhea after nasal injury.
  • Have a low threshold for ordering facial bone CT if there is suspicion for associated injuries or fractures.
