Giant Dysplastic Sinonasal Inverted Papilloma.

Area of Science:

• Otolaryngology
• Head and Neck Surgery
• Oncology

Background:

• Sinonasal inverted papilloma (IP) presents challenges due to potential malignancy, recurrence, and local invasiveness.
• Traditional treatment involves extensive local excision, but endoscopic techniques are emerging.
• Histopathological diagnosis can be complicated by dysplastic changes.

Purpose of the Study:

• To report a case of extensive sinonasal inverted papilloma managed endoscopically.
• To demonstrate the feasibility and effectiveness of the endoscopic approach for complete tumor clearance.
• To discuss diagnostic challenges and management strategies for IP with dysplasia.

Main Methods:

• Endoscopic sinus surgery for extensive sinonasal inverted papilloma.
• Histopathological examination of tumor tissue.
• Review of diagnostic and management options for sinonasal inverted papilloma.

Main Results:

• Complete clearance of an extensive sinonasal inverted papilloma was achieved using an endoscopic approach.
• The endoscopic method proved effective and less invasive than traditional open surgery.
• Diagnostic challenges related to histopathological dysplastic changes were addressed.

Conclusions:

• Endoscopic management is a viable and effective option for extensive sinonasal inverted papilloma, even with dysplastic changes.
• Complete tumor resection is achievable via endoscopic means, challenging the necessity of radical open procedures.
• Careful histopathological evaluation and tailored management are crucial for sinonasal inverted papilloma.
