Abstract:
Endoscopic medial maxillectomy (EMM) and its modifications are surgical techniques are used to treat recalcitrant maxillary sinusitis as well as maxillary sinus tumors. In this report, we propose a simple and efficient modification of EMM, called endoscopic trans-turbinal medial maxillectomy (ETTMM), by which the inferior turbinate (IT), nasolacrimal duct, and anatomical integrity of the nasal valve area are preserved. A total of 10 patients (five tumorous and five nontumorous maxillary diseases) underwent ETTMM. Briefly, a turbinate mucosal flap on the superior aspect of the IT was elevated after middle meatal antrostomy. Then a trans-turbinal window was developed to expose the inferior meatus, after which an extended maxillary antrostomy was generated. Finally, the turbinate mucosal flap was repositioned after complete removal of the antral lesions. All lesions were successfully treated using ETTMM. Our modification was easy to perform, and we achieved good endoscopic visualization and accessibility throughout the whole antrum by creating a trans-turbinal window and extended maxillary antrostomy. We could perform postoperative surveillance easily through the wide antrostomy using rigid endoscopes of various angles. ETTMM is a simple and useful modification of EMM that provides clear visualization and great accessibility to most aspects of the maxillary antrum while preserving the nasal functional units, including the IT and nasal valve area.
