Over-under cartilage tympanoplasty: technique, results and a call for improved reporting
Published online by Cambridge University Press: 06 October 2020
Abstract
This study aimed to describe the microscopic over-under cartilage tympanoplasty technique, provide hearing results and detail clinically significant complications.
This was a retrospective case series chart review study of over-under cartilage tympanoplasty procedures performed by the senior author between January 2015 and January 2019 at three tertiary care centres. Cases were excluded for previous or intra-operative cholesteatoma, if a mastoidectomy was performed during the procedure or if ossiculoplasty was performed. Hearing results and complications were obtained.
Sixty-eight tympanoplasty procedures met the inclusion criteria. The median age was 13 years (range, 3–71 years). The mean improvement in pure tone average was 6 dB (95 per cent confidence interval 4–9 dB; p < 0.0001). The overall perforation closure rate was 97 per cent (n = 66). Revision surgery was recommended for a total of 6 cases (9 per cent) including 2 post-operative perforations, 1 case of middle-ear cholesteatoma and 3 cases of external auditory canal scarring.
Over-under cartilage tympanoplasty is effective at improving clinically meaningful hearing with a low rate of post-operative complications.
