Technique for Reduction of Nasal Fractures
Paul H. Toffel
INTRODUCTION
Management of nasal fractures has evolved substantially in recent decades. Whereas closed reduction of nasal fractures was frequently attempted in the past, then followed up by secondary open reduction when inadequate correction was noted, now most experienced rhinologists and otolaryngologists will be prepared to do a definitive open reduction of nasal and septal fractures as the primary correction with much more reliable functional results. The spectrum of injuries to the nose and septum have responded much better to early open correction and prevented late obstructive and crooked pyramid sequelae. This is the philosophy best taught in current training and is becoming an improved standard of care.
HISTORY
The accurate diagnosis of severity and degree of nasal external and internal structure deformity depends on the history of causation and severity of forces involved in the injury. A fist or fall injury may be less severe than motor vehicle accidents, and the suspicion of trauma to adjacent structures must be entertained (i.e., facial, orbital fractures, neck injuries) and ruled out or treated in the emergency setting. Time since injury, degree of pain, and perceived nasal obstruction and epistaxis should all be noted.
PHYSICAL EXAMINATION
Physical examination of nasal and septal fractures requires first gross visual assessment of ecchymosis and degree of obvious deformity. Then, palpation of the external nasal structures, including bony and cartilaginous vault, should be done to detect displacement, tenderness, crepitus, and mobility.
Internal examination of the nasal vault is best done with a nasal speculum and bright headlight illumination, supplemented by nasal endoscopy when feasible. Suction and topical vasoconstriction facilitate the visual internal examination. Notation of the status of the septum is essential, that is, fractures and dislocations of the septum, mucosal tears, and septal hematoma that might need immediate drainage to prevent septal abscess and necrosis. Paramount is notation of septal displacement holding the nasal pyramid also in displacement without the ability to easily mobilize to the midline.
Photography is an essential documentation of the nasal physical examination findings and status for the assessment and medical record.
Nasal radiographs are traditionally done and help in decision making if obviously positive, but in no way counterpositive physical findings if the radiographs are negative. If the facial trauma is severe enough, maxillofacial CT scans including the nose and sinuses are indicated and can provide more detail than plane radiographs in assessing external and internal nasal structures.
INDICATIONS
If findings of nasal deformity and obstruction are confirmed, the patient should be taken to the operating suite either before edema and bruising have set in or, if present, should be delayed until they have subsided. The operating suite is the best facility in which to manage nasal and septal fracture repair, as adequate correction can be done in the proper environment without compromise. Consent should allow the surgeon to do whatever procedures are necessary, including closed or open reduction of fractures, which is a key element of informed consultation with the patient and family prior to corrective surgery.
CONTRAINDICATIONS
There are no definite contraindications to performing necessary reduction surgery, whether closed or open, for nasal and septal fractures based on local factors; however, comorbidities must be considered, especially aged, debilitated, or demented patients and associated cardiovascular, kidney, or pulmonary disease. In weak and debilitated patients, deformity may have to be accepted, but usually some degree of closed reduction can be accomplished.
PREOPERATIVE PLANNING
In the treatment of the displaced nose, closed reduction has traditionally been considered adequate management. Within the specialty of rhinology, however, closed reduction is acceptable in only the most minimally traumatized nose and nasal septum. There should be no hesitation in performing an open reduction of nasal and septal fractures if the closed reduction attempt is inadequate for straightening the nasal pyramid and restoring the intranasal respiration.
Timing of the repair is an inpatient consideration. Closed reductions may be successful in the first 10 days after trauma, but beyond that time, open reduction may be required to provide adequate alignment and repair of both nasal pyramid and septal structures because of potential healing in displaced positions.
Preoperative management of the typical patient with a nasal and septal fracture waiting for edema to resolve, prior to operative procedure, requires administering a prophylactic antibiotic, usually an oral cephalosporin, to diminish the risk of intranasal infections, especially if there have been mucosal tears. Analgesics may also be given to diminish discomfort in the acute postinjury phase.
Anesthesia for the nasal/septal reduction procedure, in the outpatient operating suite, can be selected as either IV analgesic or, for younger patients or challenging adults, general endotracheal anesthesia. In both situations, delicate and complete local anesthesia with a topical decongestant and infiltrated dilute Xylocaine with epinephrine solution is effective for vasoconstriction during the anatomic correction.
The cephalosporin antibiotics are administered IV at the time of the procedure and continued postoperatively orally, especially if light postoperative splinting or packing support is necessary.
SURGICAL TECHNIQUE
In patients with confirmed septal dislocation and nasal fracture with displacement, the septum should first be explored surgically and realigned during the same procedure as the nasal pyramid so that reconstitution can be controlled in the operating room environment in order to promote good healing, alignment, and nasal respiration and to prevent bony malunion in a crooked position.
If present, a septal hematoma should be drained expeditiously to avoid sequelae such as absorption of septal cartilage with a resultant saddle nose deformity.
