Abstract
BACKGROUND: Despite the development of functional endoscopic endonasal surgery, there are still areas of the maxillary sinus that remain technically difficult to access using a standard middle meatal antrostomy as well as deep-seated skull base lesions requiring expanded transmaxillary approaches.
METHODS: All patients who underwent transnasal endoscopic partial maxillectomy (TEPM) in a single institution from 2000 to 2014 were retrospectively reviewed. The TEPM was classified into 5 types according to the anatomic structures progressively removed and to the access provided.
RESULTS: The TEPM was performed in 1378 patients for the management of: inflammatory diseases in 513 cases (37%), benign sinonasal tumors in 425 cases (31%), skull base malignancies in 285 cases (21%), and as a corridor to address deep-seated skull base lesions in 155 cases (11%).
CONCLUSION: The TEPM is a stepwise approach offering increasing access that can be tailored to different maxillary, sinonasal, and skull base pathologies with minimal morbidity for patients. © 2016 Wiley Periodicals, Inc. Head Neck, 2016.
