Early endoscopic techniques entailed an extended maxillary antrostomy with piecemeal resection of tumor of the lateral nasal wall.

No movement of dye indicates irreversible loss of ciliary function and hence a simple widening of the already widened ostium i. Distribution of maxillary sinus volume inferior to the attachment of the inferior turbinate for 38 maxillary sinuses. Drafting of the manuscript: All patients had good disease control in the postoperative visits with no clinical evidences of recurrences.

Type Indication Procedure I Recirculation mechanism due to two windows in middle meatus and inferior meatus e. National Center for Biotechnology InformationU. Resection anterior to this structure will foster visualization.

Recently, a new surgical approach named endoscopic modified medial maxillectomy EMMM was proposed. Discussion Medial maxillectomy through a lateral rhinotomy incision involves the removal of the lateral nasal wall, ethmoid labyrinth, and medial portion of the maxilla.
