Long-term results of surgery for chronic granulating otitis

Area of Science:

• Otolaryngology
• Surgical Outcomes
• Chronic Otitis Media

Background:

• Chronic granulating otitis involves persistent ear discharge and severe mucosal pathology.
• Preoperative treatments often fail to resolve symptoms in these cases.
• Evaluating surgical approaches for chronic otitis is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze the long-term results of one-stage surgical procedures for chronic granulating otitis.
• To assess the efficacy and necessity of two-stage procedures in managing this condition.
• To determine the optimal surgical technique, specifically comparing canal-up mastoidectomy.

Main Methods:

• Analysis of late results from 229 ears undergoing planned one-stage procedures for chronic granulating otitis.
• Long-term follow-up averaging 11 years (range: 3-20 years).
• Assessment of key outcomes including ear dryness, re-perforation rates, and re-operation rates.

Main Results:

• 91% of ears were dry after the initial one-stage operation.
• The overall re-perforation rate was 12%, with 7% of ears having perforations at final follow-up.
• 98% of ears achieved dryness after potential re-operations, with a 16% re-operation rate.

Conclusions:

• Planned one-stage procedures yield high rates of ear dryness and are recommended for non-cholesteatomatous chronic granulating otitis.
• Two-stage procedures are generally not recommended for non-cholesteatomatous conditions given the success of one-stage approaches.
• Canal-up mastoidectomy is identified as the preferable surgical technique for non-cholesteatomatous granulating otitis.
