ABSTRACT

Objetive: To assess the effectiveness of the island cartilage tympanoplasty for the treatment of high risk tympanic membrane perforations compared to the use of temporalis fascia.
Material and Method: A randomized controlled clinical trial, done from January to December 2015. An initial assessment with microscope was conducted, the MERI index was determined and an initial audiometry was obtained. Patients were randomized into two groups: Group I of island cartilage tympanoplasty and Group II of temporalis fascia tympanoplasty. Patients were explored under microscope at 7, 30 and 60 days postoperatively assessing the tympanic graft integrity and a control audiometry was obtained.
Results: 69 patients were included, 33 in group I of island cartilage and 36 in group II of temporalis fascia. We found a success rate for group I of 94% at the 30 and 60 days assessment, and a rate of success of 83% at the 30 and 60 days assessment, without statistical significance (p=0.17). No statistical significant difference was found in hearing improvement results between both groups (33.1 vs 33.6 dB, p=0.88, for patients in island cartilage group and temporalis fascia group, respectively).
Conclusions: Island cartilage tympanoplasty shows excellent morphological and audiological outcomes in treatment of high risk perforations, but when compared to temporalis fascia has not shown statistical significant difference.
