Surgical technique in endoscopic posterior septoplasty for an adult patient with choanal stenosis.
The technique in endoscopic posterior septoplasty for the case of a female aged 49 with bilateral choanal stenosis is presented. This female had undergone endoscopic nasal surgery for stenosis twice before the posterior septoplasty. However, restenosis of the choanae had arisen within 2 weeks after each surgery. This patient underwent the endoscopic posterior septoplasty under general anesthesia. After removal of the cartilage and bony structures of the nasal septum, the posterior one-third of bilateral septal membranes was excised. This technique is to enlarge the choanal opening obliquely. Excellent visualization for the septoplasty using the endoscope was obtained. Sufficient patency of the choanae was achieved using this technique. There still is no restenosis of the choanae observed and the rhinomanometry shows extreme decrease of nasal airway resistance 1 year after this surgery. It is considered that endoscopic posterior septoplasty for choanal stenosis is an effective procedure with low morbidity and long-term patency.
