Abstract
The microdebrider is a surgical tool which has been used successfully in many endoscopic surgical procedures in otolaryngology. In this study, we analysed our experience using this powered instrument in the resection of obstructive nasal septum deviations. This prospective study conducted on 30 patients who consulted for chronic nasal obstruction caused by a septal deviation or deformity and underwent powered endoscopic septoplasty (PES). Patients undergoing PES had a significant reduction of nasal symptoms postoperatively compared to preoperative symptoms. All the participated patients were satisfied with the results of surgery and no patient answered {u2018}{u2018}No{u2019}{u2019} to the question added to compare patient satisfaction after surgery. Therefore, Powered endoscopic septoplasty allows accurate, conservative repair of obstructive nasal septum deviations, with fewer complications and better functional results. In our experience, this technique offered significant perioperative advantages with high postoperative patient satisfaction in terms of reducing the severity of nasal symptoms
