Transnasal endoscopic medial maxillectomy in inverted papilloma

Area of Science:

• Otolaryngology
• Head and Neck Surgery
• Endoscopic Sinus Surgery

Background:

• Inverted papilloma is a benign but locally aggressive sinonasal tumor.
• Accurate diagnosis and appropriate surgical management are crucial to prevent recurrence.
• Differentiated treatment strategies based on tumor extent are essential.

Purpose of the Study:

• To evaluate the efficacy of different endoscopic surgical techniques for inverted papilloma based on tumor location.
• To compare outcomes for inverted papilloma with and without maxillary sinus involvement.
• To establish optimal surgical management guidelines for sinonasal inverted papilloma.

Main Methods:

• Retrospective analysis of 17 inverted papilloma cases.
• Group 1 (8 cases): Intranasal endoscopic resection for tumors without maxillary sinus involvement.
• Group 2 (9 cases): Transnasal endoscopic medial maxillectomy for tumors involving the maxillary sinus.

Main Results:

• No recurrence observed in either group after an average follow-up of 43 months (Group 1) and 28 months (Group 2).
• Intranasal endoscopic resection demonstrated effectiveness for tumors limited to the nasal cavity.
• Transnasal endoscopic medial maxillectomy proved safe and effective for maxillary sinus-invasive inverted papilloma.

Conclusions:

• Inverted papilloma management should be tailored to its anatomical extent.
• Intranasal endoscopic resection is suitable for non-maxillary sinus inverted papillomas.
• Transnasal endoscopic medial maxillectomy is the recommended approach for inverted papillomas invading the maxillary sinus.
