Summary

This study is designed to evaluate whether the addition of nasopharyngeal lymphoid tissue ablation to full-house endoscopic sinus surgery (ESS) provides superior control of nasal mucosa inflammation compared to full-house ESS alone in patients with nasal polyps. Thirty-two adult participants will be randomly assigned to undergo either full-house ESS only or full-house ESS combined with nasopharyngeal lymphoid tissue ablation. The primary outcome will be assessed through changes in inflammatory cell profiles at 1, 3, and 6 months postoperatively. Secondary outcomes include inflammatory cytokine levels, symptom scores, endoscopic findings, polyp recurrence rates, and safety measures.

Conditions

  • Nasal Polyps

Interventions

PROCEDURE

Nasopharyngeal Lymphoid Tissue Ablation

The nasal mucosa is initially decongested using a topical vasoconstrictor. A small-caliber urethral catheter is then introduced through each nasal cavity to elevate the soft palate. A 45° rigid nasoendoscope is inserted transorally to visualize the nasopharynx. Under endoscopic guidance, the nasopharyngeal lymphoid tissue is identified on the nasopharyngeal roof. Following aspiration of any secretions, the tissue is completely resected with a plasma scalpel.

PROCEDURE

Full-House Endoscopic Sinus Surgery

After complete removal of the nasal polyps, a full ethmoidectomy is performed, removing all bony septa within the sinuses. Conventional sphenoidotomy and frontal sinusotomy are carried out, with or without preservation of the middle turbinate. Only irreversibly polypoid mucosa is resected, while normal mucosa is preserved.
