ENDOSCOPIC MOBILIZATION AND REPOSITIONING OF MEDIAL MAXILLARY WALL FOR MANAGEMENT OF MAXILLARY SINUS DISEASES

Background: Some maxillary sinus lesions cannot be removed completely through the middle meatus antrostomy (MMA), and remnants of the lesion may be present. Also, wide middle meatal antrostomy or medial maxillectomy may lead to complications like nasolacrimal duct and inferior turbinate injury. Aim: To describe the effect of endoscopic mobilization and repositioning of the medial maxillary wall in the management of maxillary sinus diseases. Subjects and methods: This prospective study was conducted on 40 patients with maxillary sinus diseases (20 patients had inverted papilloma and 20 patients had antrochoanal polyp) who were admitted to Al-Azhar University hospitals from July 2023 to March 2025. Results: The endoscopic mobilization and repositioning of the medial maxillary wall is effective in improving accessibility to the whole maxillary sinus and residual detection. There is recurrence in 2 patients with inverted papilloma and in one patient with an antrochoanal polyp. No major complications occurred during the follow-up. Conclusion: One reasonable surgical option for maxillary sinus lesions is the endoscopic medial maxillary wall realignment and mobilization treatment. Compared to more traditional methods, it seems to cause less morbidity and has fewer restrictions.
