Long-term results of pediatric primary one-stage cholesteatoma surgery
Insights
Pediatric cholesteatoma surgery recurrence was 29%. Factors like ear discharge and poor ventilation increased risks, while hearing was preserved. Surgical technique improvements are crucial for better outcomes.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Surgical Outcomes
Background:
- Surgical treatment for pediatric cholesteatoma lacks consensus on methods and outcomes.
- Long-term results and recurrence factors require further investigation.
Purpose of the Study:
- To analyze long-term surgical outcomes for pediatric cholesteatoma.
- To identify factors contributing to cholesteatoma recurrence after surgery.
Main Methods:
- Retrospective analysis of 84 pediatric cholesteatoma surgeries at Helsinki University Central Hospital.
- All surgeries involved mastoid obliteration and bony ear canal reconstruction without open cavities.
- Independent evaluation with an average follow-up of 4.8 years.
Main Results:
- Overall recurrence rate was 29% (24/84), not linked to cholesteatoma size or specific erosion.
- Retraction developed in 25% of ears, with 42% progressing to cholesteatoma.
- Retractions combined with postoperative discharge significantly increased recurrence risk.
Conclusions:
- Reduced middle ear and attic ventilation contribute to retractions and atelectasis, accelerating recurrence.
- Surgical pitfalls in mastoid obliteration and attic reconstruction, along with inadequate ventilation routes, are key recurrence drivers.
- Hearing levels were maintained, but recurrence remains a significant challenge in pediatric cholesteatoma management.
Abstract:
The long-term results of surgical treatment for pediatric cholesteatoma are variable and there is no consensus on operation methods and on factors affecting outcome of surgery. We analyzed the independently evaluated long-term results and possible reasons for recurrence of cholesteatoma. A total of 84 consecutive pediatric (age < 16 years) cholesteatoma operations in the Helsinki University Central Hospital ENT Department. The operations were not staged, and all mastoids were obliterated and bony ear canals reconstructed without open cavities. The pre- and postoperative and annual control data were recorded in a database. The last control was independently performed (JS) with an average follow-up of 4.8 years and 87% attendance. The total recurrence rate was 29% (24/84), and it was not dependent on the size of cholesteatoma, mastoid status, cholesteatoma in the window niches or stapedial erosion. A retraction process developed in 25% (21/84) of the ears and 42% (9/21) of these turned into retraction pocket cholesteatomas as late as 13 years postoperatively. Retractions and postoperative discharge, especially in combination, predisposed to recurrence. Of the healed ears, 37% became atelectatic. Hearing was maintained on the preoperative level. Reduced middle ear and attic ventilation led to retractions, and atelectasis and a tendency to discharge accelerated the process. Pitfalls in mastoid obliteration and attic reconstruction and the failure to create new ventilation routes were important reasons for recurrence of cholesteatoma.
