ENDOSCOPIC ENDONASAL TREATMENT OF PRIMARY INVERTED PAPILLOMA OF THE SPHENOID SINUS: A CLINICAL CASE

Area of Science:

• Otorhinolaryngology
• Neurosurgery
• Oncology

Background:

• Inverted papilloma is a rare sinonasal tumor.
• Primary sphenoid sinus involvement is uncommon.
• Surgical management requires specialized techniques.

Purpose of the Study:

• To present a case of primary sphenoid sinus inverted papilloma.
• To describe the endoscopic endonasal approach with posterior septectomy.
• To correlate clinical and radiological findings with surgical outcomes.

Main Methods:

• Case report of a 30-year-old male with chronic sinonasal symptoms.
• Diagnostic workup included nasal endoscopy, CT, and MR imaging.
• Surgical resection via endoscopic endonasal approach with posterior septectomy, confirmed by histopathology.

Main Results:

• Successful endoscopic resection achieved in 95 minutes with minimal blood loss (80 mL).
• No intraoperative or postoperative complications, including bleeding or infection.
• Significant symptom improvement (headache, nasal obstruction) and olfactory recovery within six weeks.
• Six-month follow-up CT showed no evidence of recurrence.

Conclusions:

• Endoscopic surgery with posterior septectomy is feasible for primary sphenoid sinus inverted papilloma.
• Complete resection was achieved without major complications.
• This approach offers short-term disease control with favorable functional outcomes.
