Inverted papilloma - an analysis of 30 cases

Area of Science:

• Otolaryngology
• Head and Neck Surgery
• Oncology

Background:

• Inverted papilloma (IP) is a benign neoplasm of the sinonasal tract.
• IPs are characterized by local aggressiveness and a propensity for recurrence.
• A significant proportion of patients present with a history of prior surgical interventions.

Purpose of the Study:

• To analyze clinical, radiological, and surgical outcomes for inverted papilloma patients.
• To evaluate the effectiveness of radical surgery in managing sinonasal inverted papillomas.
• To assess recurrence rates and the incidence of malignant transformation in treated IPs.

Main Methods:

• Retrospective analysis of 30 patients diagnosed with inverted papilloma treated between 1990-1995.
• Clinical data, radiological findings (CT scans), and surgical procedures were reviewed.
• Follow-up data regarding recurrence and malignant changes were collected.

Main Results:

• Unilateral nasal obstruction, with or without epistaxis, was the most frequent presenting symptom.
• CT scans proved valuable for delineating tumor extent and surgical planning.
• Radical surgery was performed in all cases, resulting in a 3.3% recurrence rate and 6.6% incidence of carcinomatous change.

Conclusions:

• Radical surgical excision is an effective treatment for inverted papilloma.
• Early and accurate diagnosis using CT imaging is crucial for optimal surgical planning.
• Close monitoring is essential due to the potential for recurrence and malignant transformation in inverted papillomas.
