Innovative instrument for natural sphenoid ostium enlargement

Abstract

Background: Advances in the surgical treatment of chronic sphenoiditis are not possible without the development of specialized instruments for manipulation in the sphenoethmoidal recess. The creation and clinical implementation of innovative tools for sphenoidotomy remain a relevant objective in modern rhinologic surgery.

Aim: To present the outcomes of using an innovative instrument designed for the enlargement of the natural sphenoid sinus ostium.

Methods: The instrument was developed by the Departments of Otorhinolaryngology of the Russian Medical Academy of Continuous Professional Education (Kazan branch) and Kazan Federal University. The proposed device Forceps for opening and enlarging the sphenoid ostium with a pathological tissue removal function is engineered to account for the anatomy of the anterior sphenoid wall and enables minimally invasive medial partial resection of the natural ostium.

Results: In the first stage of this study, anatomical experiments were conducted on 12 sphenoid sinuses from 6 cadavers, using the forceps for opening and enlarging the sphenoid ostium. The second stage included surgical treatment of 11 patients with isolated sphenoiditis. The performed resection created favorable conditions for reparative regeneration of tissue from the intact regions of the natural ostium, thereby preventing stenosis or fibrotic obliteration.

Conclusion: Clinical use of the Forceps for opening and enlarging the sphenoid ostium with a pathological tissue removal function demonstrated an absence of complications such as stenosis or fibrotic obliteration of the sphenoid ostium.
