Otoendoscopy for improved pediatric cholesteatoma removal

Area of Science:

• Otolaryngology
• Surgical Technology
• Pediatric Surgery

Background:

• Cholesteatoma surgery aims for complete removal to prevent recurrence.
• Traditional otomicroscopy may miss residual disease.
• The role of intraoperative endoscopy in pediatric cholesteatoma surgery requires evaluation.

Purpose of the Study:

• To assess the efficacy of intraoperative rigid endoscopy in identifying incompletely removed cholesteatoma.
• To determine if "second-look" procedures remain necessary in children after endoscopic evaluation.

Main Methods:

• Rigid 2.7-mm, 30-degree endoscopes were used to examine the middle ear after initial microscope removal of cholesteatoma.
• Procedures involved continued endoscopic removal if residual disease was detected.
• Planned exploratory surgeries were performed if cholesteatoma was not removed intact.

Main Results:

• Intraoperative endoscopy detected incompletely removed cholesteatoma in 24% (7/29) of cases.
• Residual cholesteatoma was found in 18% (2/11) of cases initially deemed clear by both otomicroscopy and otoendoscopy.
• A substantial rate of residual disease was identified even after seemingly complete removal.

Conclusions:

• Intraoperative rigid endoscopy is a valuable tool for detecting residual cholesteatoma during surgery.
• Despite endoscopic findings, a significant incidence of residual disease persists.
• Planned exploratory "second-look" procedures remain essential in pediatric cholesteatoma management.
