BACKGROUND: Nasal septal perforations pose a troubling source of morbidity for patients and a difficult problem for the otolaryngologist. Multiple surgical techniques have been tried, with inconsistent success. Prosthetic nasal buttons also have limitations, including patient intolerance and dissatisfaction. Acellular human dermal allograft (AlloDerm) has been described as an alternative material for septal perforation repair. The authors studied objective and subjective outcomes, including quantification of the patient's symptoms in septal perforation repair with AlloDerm.

METHODS: The authors performed a prospective cohort study of 12 patients with 1- to 2-cm anterior septal perforations who were recruited from a tertiary care practice. Patients with admitted smoking or cocaine use in the previous 3 months or vascular or granulomatous diseases were excluded. Subjective scores on the Sino-nasal Outcome Test-22, along with objective nasal endoscopy and acoustic rhinometry measures, were collected at baseline and 2, 4, and 12 weeks postoperatively. Patients were followed for reperforation 9 to 20 months postoperatively. Data were normalized to baseline values and analyzed using analysis of variance and Bonferroni correction.

RESULTS: Successful closure of the septal perforation was obtained in 10 of 12 patients and confirmed with rigid nasal endoscopy. Nasal symptom scores (Sino-nasal Outcome Test-22 ) were significantly reduced to 52.8 percent (95 percent CI, 35.1 to 70.5 percent; p < 0.01) of baseline symptoms at 4 weeks postoperatively. At 12 weeks postoperatively, symptoms were measured at 26.6 percent (95 percent CI, 10.9 to 42.1 percent; p < 0.01) of baseline symptoms. Acoustic rhinometry confirmed perforation closure, demonstrating a reduction in cross-sectional nasal area from baseline of 55.1 percent (95 percent CI, 37.7 to 66.8 percent; p < 0.01).

CONCLUSION: This is the first study to use objective and subjective measurements to confirm success with acellular dermis allograft as an adjunct for septal perforation repair, demonstrating a statistically significant reduction in patient nasal symptoms following repair.
