Modified Midfacial Degloving Approach for Sinonasal Tumors

Abstract

A perfect surgical approach to nasal cavity and paranasal sinus tumors should provide a broad exposition preserving the important structures with no cosmetic defect. Midfacial degloving (MD) technique provides good exposure without incisions and scars in the face. Classic MD technique includes rhinoplasty incisions. However, combination of the facial plastic skills of the rhinoplasty techniques with an oncologic approach limits its popularity. We modified the classic technique, which is performed without classic rhinoplasty incisions. The surgical approaches to 55 patients with benign and malignant sinonasal neoplasms are reviewed, and the modification of MD technique performed without rhinoplasty incisions is described. The study includes 41 male and 13 female patients with both benign and malignant sinonasal neoplasms. The ages of the patients were between 9 and 78 years with a mean age of 41.15 years. Follow-up of the patients ranged from 2 to 96 months with a mean of 31.7 months. Most of the cases were angiofibroma and inverted papilloma. Modified MD approach was used for all patients, and in 6 cases, the technique was combined with subcranial approach. We successfully resected the tumors in all of the patients. The most frequently encountered complaint in the postoperative period was temporary nasal crusting and epistaxis. An important complication was the rupture of subpetrous part of the internal carotid artery in one patient and also a temporary facial palsy in another one. Palatal dysfunction, oroantral fistula, or vestibular stenosis, which are significant complications of MD, were not observed in any of our cases. In this modified technique, rhinoplasty incisions are not used; therefore, the duration of operation is shortened, the technique becomes easier, and the incisions of the rhinoplasty procedure, which could cause circular stenosis, are avoided.
