Objective: To evaluate surgical outcomes of retrograde mastoidectomy when using soft-wall reconstruction in pediatric cholesteatoma.Study Design: Retrospective case review.
Setting: Tertiary referral center.Patients: A total of 25 children underwent cholesteatoma removal surgery employing soft-wall reconstruction. Average follow-up time was 48.7 months.Intervention: In order to fully expose and extirpate the disease, the bony canal wall was removed in association with a retrograde-type mastoidectomy in all cases. The posterior ear canal defect was then reconstructed using soft-tissue; i.e., temporal fascia and canal wall skin.
Main Outcome Measures:The incidence and localization of residual and recurrent cholesteatoma, preoperative and postoperative audiogram results, pure-tone average, and air-bone gap were assessed.
Results:Residual cholesteatoma was detected in 5 (20%) out of 25 ears. There were 4 small residual cholesteatomas that were located in the posterior tympanic sinus, on the stapedial tendon, on the stapes head, and in the epitympanum, respectively. As we found aggressive residual disease in 1 case, the total recurrent cholesteatoma was 1 (4%) out of 25 ears. The mean preoperative pure-tone average (PTA) of air conduction (AC) was 39.1 dB, while the preoperative PTA of the air-bone gaps (ABG) was 28.8 dB. At 6 months or more after the last surgical intervention, the mean postoperative PTA-AC and PTA-ABG were 20.9 dB and 11.7 dB, respectively. The mean hearing gain was 18.1 dB.The differences between the pre-and postoperative values were statistically significant (p < 0.05).
Conclusion:Retrograde mastoidectomy with soft-wall reconstruction is an effective technique that can be used to lower the recurrence rate of cholesteatoma in the pediatric population.
