Functional Septorhinoplasty in Unilateral and Bilateral Nasal Obstruction: A Comparison of Patient-Reported Outcomes

Purpose: Functional septorhinoplasty is an effective treatment for nasal airway obstruction. Little distinction exists between bilaterally and unilaterally obstructed patients in literature. Our study evaluates outcomes in patients with unilateral nasal airway obstruction compared to those with bilateral nasal airway obstruction as measured by nasal obstruction symptom evaluation scores following functional septorhinoplasty.

Materials and methods: A total of 227 patients underwent functional septorhinoplasty for nasal airway obstruction. Patients were grouped into unilateral (n = 64) and bilateral (n = 163) nasal obstruction cohorts based on patient report and physician assessment. Nasal obstruction symptom evaluation (NOSE) scores were obtained pre-operatively and post-operatively at least 3 months following surgery.

Results: Patients with unilateral nasal obstruction had slightly less severe symptoms preoperatively than patients with bilateral obstruction. Average preoperative NOSE scores for patients with unilateral obstruction was 64 (SD = 19) and 72 (SD = 18) for patients with bilateral obstruction (P = .004). Postoperative NOSE scores following septorhinoplasty were significantly reduced for patients with both unilateral and bilateral nasal obstruction (postoperative NOSE scores unilateral: 17, SD = 16 ; bilateral: 23, SD = 21). There was no statistical significance in outcomes between patients with unilateral or bilateral nasal obstruction groups.

Conclusions: Symptoms in patients with unilateral obstruction are similar but slightly less severe than patients with bilateral obstruction. Patients with unilateral and bilateral nasal obstruction experienced a similar degree of improvement in symptom following functional septorhinoplasty.
