The surgical treatment of cholesteatoma in children
Insights
The intact canal wall technique (ICWT) for pediatric cholesteatoma surgery requires a second stage in most cases to manage residual disease. Obliteration techniques may be necessary if retraction pockets form, impacting long-term outcomes.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Surgical Techniques
Background:
- Cholesteatoma in children presents unique surgical challenges.
- The intact canal wall technique (ICWT) is a common surgical approach.
- Managing residual cholesteatoma and preventing recurrence are critical.
Purpose of the Study:
- To evaluate the outcomes of different surgical techniques for pediatric cholesteatoma.
- To assess the efficacy of staged procedures and obliteration techniques.
- To analyze factors influencing residual cholesteatoma rates and hearing results.
Main Methods:
- Retrospective analysis of 141 pediatric cholesteatoma cases (ages 3-15) operated between 1966-1981.
- Comparison of radical mastoidectomy, open cavity tympanoplasty, and intact canal wall technique (ICWT).
- Evaluation of staged ICWT, obliteration techniques, and management of retraction pockets.
Main Results:
- ICWT was performed in 99 cases, with 83 planned for a second stage to control residual cholesteatoma (50% in children vs. 22% in adults).
- Obliteration techniques were used in 34 cases due to extensive residual disease or retraction pockets.
- Late retraction pockets occurred in 20-25% of cases, with transformation to obliteration recommended at the second stage.
Conclusions:
- Staged ICWT is crucial for managing pediatric cholesteatoma, with a high rate of residual disease necessitating further intervention.
- Transformation to obliteration techniques is vital for addressing persistent or recurrent cholesteatoma and retraction pockets.
- Preservation of an intact stapes is associated with better hearing outcomes.
Abstract:
Between 1966 and 1981, 141 cholesteatomas were operated upon in children who were 3-15 years old. Radical mastoidectomy was performed in 5 cases. Open cavity tympanoplasty was done in 3 cases. Intact canal wall technique was performed in 99 cases, with a planned second stage in 83 cases (all cholesteatoma cases since 1973). ICWT avoids a large cavity in a well pneumatized mastoid and the second stage controls residual cholesteatomas which were more frequent in children (50%) than in adults (22%). Because of multiple or large residual cholesteatomas, a third stage was performed in 3 cases. Because of a large mesotympanum and/or attic residual cholesteatoma, a transformation of ICWT to an obliteration technique was performed in 4 cases. Retraction pockets were found after the first stage in 12 cases and a transformation of ICWT to an obliteration technique was done in 8 cases at the second stage. Late retraction pockets were found after 5 years in 20% after 2 stages and in 25% after one stage. If a retraction pocket is observed at the second stage, transformation of ICWT to an obliteration technique must be performed. Obliteration technique was performed in 34 cases. A second stage was planned in 26 cases only if the mesotympanum was to be dissected raw. Hearing results were better with an intact stapes (56% of air-bone gap less than or equal to 20 dB).
