Although transnasal endoscopic medial maxillectomy (TEMM) is effective for the treatment of inverted papilloma (IP) in maxillary sinus (MS), it involves resection of the inferior turbinate (IT). TEMM also involves resection of the nasolacrimal duct (ND) in many cases to gain better access. Therefore, we developed a novel procedure in which the preserved IT and ND are shifted medially for a complete resection of IP in the MS. Incision was made in the mucosa of the lateral wall along the anterior margin of the IT. After removal of the medial maxillary wall except the ND and the lateral nasal mucosa, the anterior lateral mucosa of the nose, including the IT and the ND, was shifted in the medial direction to allow wider access to the MS. The tumor was removed together with the attachment through the anterior side of the ND. This modified TEMM was performed in 10 patients with IP. The IT and ND were preserved in all patients. We have not observed epiphora after this surgery. The advantages of the novel approach presented herein include: 1) preservation of the IT, ND, and lateral nasal mucosa; 2) wide access to the MS by shifting the IT, ND, and lateral nasal mucosa in the medial direction; and 3) direct access to the MS through anterior space of the ND, resulting in easier operation with a straight endoscope and instruments. This approach is a safe and effective method to obtain wide and straight access to the MS and to resect IP in the MS.
