Objective: To introduce a novel cartilage trap-door flap technique in endonasal septoplasty to correct high dorsal deviation of the cartilaginous septum, and confirm its effectiveness.

Design: Prospective observational study.

Setting: Medical center.

Methods: 46 patients who had underwent septoplasty using the cartilage island flap technique to correct the high dorsal deviation from November 2014 to November 2015. The subjective symptoms were measured using the Nasal Obstruction Symptom Evaluation scale. The objective evaluations of the surgical results were analyzed using acoustic rhinometry. Post-operative status of the nasal septum was estimated by nasal endoscopic examination.

Results: Among 46 patients, 32 cases (69.57%) were “complete correction”, 14cases (30.43%) were “improved” with residual deviation and there was not “no-change” or “even worse” case based on endoscopic examination. Minimal cross-sectional area in convex side of nasal cavity was significantly changed from 0.22cm2 to 0.56cm2 after the surgery, and nasal volume in narrower side of nasal cavity was significantly changed from 2.44mL to 6.22 mL. The patients’ nasal obstruction symptoms significantly reduced from 10.43 before the surgery to 1.45 after the surgery. During the follow-up period, the authors have not experienced any obvious complications such as saddle nose, septal perforation, and bleeding.

Conclusion: The proposed cartilage trap-door flap technique provides easy and effective results for dorsal deviations of the cartilaginous septum in selected cases without significant complications.
