Simultaneous intranasal procedures to improve chronic obstructive nasal breathing in patients undergoing maxillary (le fort I) osteotomy.

PURPOSE: The aim of this study was to evaluate the safety and efficacy of septoplasty and inferior turbinate reduction, carried out through a Le Fort I osteotomy as part of the correction of a dentofacial deformity, designed to improve nasal breathing in patients who reported pre-existing nasal airway obstruction and had documented septal deviation and inferior turbinate hypertrophy.

PATIENTS AND METHODS: A validated outcomes instrument, the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, was used to objectively assess the extent of clinical nasal obstruction both before and after septoplasty and inferior turbinate reduction performed at the time of Le Fort I down-fracture. The study group comprised 43 consecutive patients scheduled for orthognathic surgery (including Le Fort I osteotomy) over a 12-month period who complained of chronic nasal obstruction and were found (by an independent otolaryngology evaluation) to have septal deviation and inferior turbinate hypertrophy unresponsive to medical therapy, who met the inclusion criteria, and who agreed to the procedures (septoplasty and turbinate reduction). The data collected included age, gender, health and social history, type of dentofacial deformity, concomitant surgical procedures, and any associated postoperative complications.

RESULTS: For the 43 study patients, significant improvement in nasal breathing was documented (by NOSE scores) at 3 months (P < .001) after the procedures (Le Fort I osteotomy, septoplasty, and inferior turbinate reduction). Comparison of the 3-month and 6-month NOSE scores showed maintenance of improved nasal breathing with further improvement that did not demonstrate statistical significance.

CONCLUSIONS: The findings of this study indicate that simultaneous management of the maxillary jaw deformity (Le Fort I osteotomy) and intranasal pathology (septoplasty and reduction of inferior turbinates) were effective for the symptomatic relief of nasal airway obstruction. The complication rate for the intranasal procedures completed simultaneously with a Le Fort I osteotomy was minimal and not dissimilar to the rates reported for each procedure performed as an isolated event.
