Endoscopic Endonasal Repair of Septal Perforation with Interpositional Auricular Cartilage Grafting via a Mucosal Regeneration Technique.

We evaluated the efficacy of interpositional auricular cartilage grafting for perforation with an endoscopic endonasal approach via a mucosal regeneration technique. In total, 12 patients with symptomatic septal perforations were operated on by way of an endoscopic endonasal approach after an adequately sized cartilage graft was harvested. The graft was inserted between the circumferentially incised and elevated flaps of the perforation and secured by vertical and horizontal nonabsorbable aligning approximation stitches and prolonged placement of silicone splints. The average perforation size was 12.3 mm (range, 4-19 mm). Bleeding, incrustation, pain, whistling respiration, and nasal congestion symptoms were relieved entirely in 10 of 12 patients (83.3%) who had successful treatment. This study showed that an endoscopic endonasal approach via a mucosal regeneration technique without direct mucosa-to-mucosa repair can be applied successfully without disrupting the neighboring nasal structures for septal perforations up to 20 mm and as effectively as other, more complex surgical interventions.
