Abstract

Objective: 1) To evaluate 3 methods: conchal cartilage, tragal cartilage, and bone pate, for primary attic reconstruction (scutumplasty) in pediatric canal wall-up mastoidectomies in terms of recurrence rates and formation of retraction pockets. Method: All patients undergoing attic reconstruction following a canal wall up mastoidectomy were evaluated from a single surgeon prospective pediatric otological database maintained over a 10-year period. The reconstruction of the scutum defects was done using bone pate, conchal and tragal cartilage. The outcome measures were postoperative retraction pocket formation and recurrence of cholesteatoma. Results: A total of 120 patients underwent primary attic reconstruction following canal wall-up mastoidectomy over a 10-year period. The overall recurrence rate was 9.83% (n = 12). Fifty-one patients underwent attic reconstruction with tragal cartilage, while 33 were reconstructed using conchal cartilage and 36 with bone pate. The recurrence rate with various reconstruction methods was 5.8% (n = 2), 15.1% (n = 5), and 13.8% (n = 5) for tragal, conchal, and bone pate, respectively. Cholesteatoma recurrence rates with the use of tragal cartilage for reconstruction of the scutum were significantly lower as compared to that of conchal cartilage ( P = .034, chi square = 3.308) and bone pate ( P = .046, chi square = 2.834). Conclusion: The use of the tragal cartilage for scutum reconstruction is associated with the least recurrence rate for pediatric cholesteatoma. The easy accessibility, stability, and good long-term results with the use of the tragal cartilage makes it an ideal material for outer attic wall reconstruction in pediatric canal wall up mastoidectomies.
