Long-term outcomes of cartilage-buttressed T-tube tympanoplasty for prolonged middle ear ventilation.

OBJECTIVES/HYPOTHESIS: To report on the safety and efficacy of cartilage-buttressed T-tube tympanoplasty for long-term middle ear ventilation, specifically by examining duration of tube survival, as well as adverse events associated with prolonged middle ear intubation, including persistent tympanic membrane perforation.

STUDY

DESIGN

Retrospective case series of patients undergoing cartilage-buttressed T-tube tympanoplasty between January 2005 and December 2016 in a tertiary-care neurotology private practice.

METHODS

Patients who underwent cartilage T-tube tympanoplasty with complete pre- and postoperative audiometric data and a minimum follow-up duration of 12 months were analyzed. T-tube survival and adverse events including persistent tympanic membrane perforation were recorded and compared to published data for other long-term middle ear ventilation techniques.

RESULTS

The study cohort included 72 cartilage-buttressed T-tube tympanoplasties in 68 patients. Median tube survival was 34 months (range, 2-131 months). Incidence of persistent tympanic membrane perforation (n = 1) was 1.4%

CONCLUSIONS

Cartilage-buttressed T-tube tympanoplasty is a safe and effective means of accomplishing long-term middle ear ventilation with a considerably lower rate of persistent tympanic membrane perforation as compared to alternative methods of prolonged middle ear ventilation.
