Antrochoanal polyp - Validating its origin and management by endonasal endoscopic sinus surgery (eess)

Area of Science:

• Otolaryngology
• Surgical Innovation
• Rhinology

Background:

• Antrochoanal polyps are benign growths originating in the maxillary sinus.
• Accurate identification of the polyp's origin is crucial for complete surgical removal.
• Endoscopic endonasal sinus surgery (EESS) offers a minimally invasive approach for sinonasal pathologies.

Purpose of the Study:

• To evaluate the efficacy of endoscopic endonasal sinus surgery (EESS) in treating antrochoanal polyps.
• To determine the primary site of origin for antrochoanal polyps within the maxillary sinus.

Main Methods:

• A prospective study involving 20 patients diagnosed with antrochoanal polyps.
• All patients underwent endoscopic endonasal sinus surgery (EESS).
• Pre- and post-operative transnasal sinuscopy was performed for evaluation.

Main Results:

• The majority of polyps (1.5 times more common) occurred on the left side.
• Unilateral nasal obstruction was the primary symptom in 100% of cases.
• The infrolateral wall of the maxillary sinus was the most frequent origin site (7 out of 12 cases).

Conclusions:

• Endoscopic endonasal sinus surgery (EESS) is the preferred treatment for antrochoanal polyps.
• The study demonstrated a high success rate of 95% for EESS in this patient cohort.
• Understanding the origin site aids in surgical planning and achieving complete resection.
