    Endoscopic sinus surgery (ESS) widely conducted in nasal and paranasal sinus surgery provides superior magnification, illumination, and angled visualization, enabling the surgeon to isolate the tumor base and accurately define disease extent. Endoscopic medial maxillectomy (EMM), an advanced ESS procedure, effectively treats benign sinonasal neoplasms such as inverted papilloma. We analyzed a series of EMM cases and their clinical outcomes, including 9 inverted papillomas, 1 solitary fibrous tumor, 1 hemangioma, 1 blood boil and 1 esthesioneuroblastoma. EMMs were conducted by an experienced surgeon. Removal of the medial wall and the wide maxillary sinus opening enabled by EMM allows easy access to the entire maxillary sinus with a generous work space. All tumors were treated endoscopically and the postoperative course was uneventful. No recurrence was observed in follow-up. We found EMM to be safe and efficacious in resecting maxillary sinus tumors thanks to its improved accessibility and visualization. In conclusion, EMM enables complete removal of benign tumors from the maxillary sinus, having the advantages of no external incision, decreased blood loss, low morbidity, shorter hospital stay, and the possibility of repetition in recurrence, compared to conventional approaches. EMM may thus become the treatment of choice for maxillary sinus tumors.

    Distant metastasis from differentiated thyroid carcinoma is rare and metastasis to the paranasal sinus is extremely rare. We report a case of differentiated papillary thyroid carcinoma (PTC) with metastases to the sphenoid sinus presenting with epistaxis. An 81-year-old undergoing partial lobectomy for differentiated PTC 9 years earlier presented with intermittent epistaxis. Imaging showed a mass filling the sphenoid sinus and extending to the intracranial cavity. Histopathological diagnosis using endoscopic biopsy indicated a metastatic PTC tumor. Compared to the primary site, the metastatic tumor was poorly differentiated thyroid carcinoma. Despite external beam radiation therapy, her general condition worsened and she was moved to a hospice.

    We report two cases of otitis media positive for antimyeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) associated with facial palsy. Case 1: A 73-year-old man treated for 3 months for bilateral otitis media with effusion had left facial nerve palsy and deteriorated bone conduction hearing in both ears. Blood analysis showed elevated MPO-ANCA to 134 EU. Case 2: A 66-year-old woman treated for about one year for bilateral otitis media with effusion and fluctuating mixed hearing loss had bilateral facial nerve palsy and a blood test positive for MPO-ANCA at 67 EU. Both were diagnosed with otitis media caused by ANCA-related vasculitis. After prednisolone and cyclophosphamide administration for half a year, blood test results were negative for MPO-ANCA. Both recovered almost completely from facial nerve palsy and bone conductive hearing loss partially improved except in one hearing-impaired ear. ANCA-related vasculitis of the temporal bone should thus be considered in those with intractable otitis media and deteriorated bone conduction hearing before the occurrence of facial palsy.
