Purpose of review The endoscopic medial maxillectomy (EMM) has remained a relevant procedure for certain sinus diseases and at the same time reemerged as a salvage technique or even as a primary procedure for other diseases. Several mucosal-sparing techniques have also been described and the outcome of the surgeries is available for review. Recent findings Modifications of the EMM technique in the last two decades, aimed at mucosal preservation of the inferior turbinate, nasolacrimal duct, and medial maxillary wall have been successful in addressing a multitude of diseases. There are also evidences to support adjunct procedures/methods to improve access, healing, and to address associated dysfunction such as impaired mucociliary clearance. Tailored approaches have shown favourable outcomes with a low rate of adverse effects. Summary The EMM is appropriate for selected indications, in particular lesions causing medial wall destruction or extensive tumour involving the anterior wall or the prelacrimal recess. As for other maxillary sinus diseases including those identified to a limited site, a modified EMM is a reasonable consideration. The choice is appropriate provided instrument access, visualization, the ability for complete resection, postoperative care, and the requirement for surveillance is not compromised. A tailored approach with or without adjunct procedures is recommended.
