[Virtual endoscopy evaluation of congenital aural atresia]

Area of Science:

• Otolaryngology
• Medical Imaging
• Surgical Planning

Background:

• Congenital aural atresia presents unique challenges for surgical intervention.
• Accurate preoperative assessment is crucial for successful surgical outcomes.

Purpose of the Study:

• To evaluate the utility of virtual endoscopic visualization (VE) for preoperative assessment of congenital aural atresia.
• To determine the correlation between VE findings and intraoperative exploration.

Main Methods:

• High-resolution computed tomography (CT) of the temporal bone was performed on 20 patients with congenital aural atresia.
• Virtual endoscopic visualization (VE) was utilized for 3D processing and analysis.
• Eight patients subsequently underwent congenital aural atresiaplasty.

Main Results:

• VE demonstrated high accuracy in evaluating the stapes (87.5%), malleus-incus complex (100%), tympanic facial nerve (100%), incus-stapes joint (75%), round window niche (100%), and middle ear space (100%).
• VE assessment demonstrated excellent concordance with intraoperative findings.

Conclusions:

• Virtual endoscopic visualization is a valuable tool for the preoperative assessment of congenital aural atresia.
• This imaging technique facilitates individualized surgical planning and simulation.
