Cartilage graft or fascia in tympanoplasty in patients with low middle ear risk index (anatomical and audological results)

摘要: The aim of this study was to compare anatomic and audiological results cartilage graft with temporal fascia in type 1 tympanoplasty patients low middle ear risk index (MERI). In retrospective study, 63 that underwent chondroperichondrial island between July 2009 November 2010 were compared 45 whom muscle used. Patients both groups had MERI values varying 3. Five nine masteidectomy group, respectively. Mean duration follow-up 11.9 ± 3.7 (5–17) months. value calculated at pre-operative post-operative hearing threshold 0.5, 1, 2, 4 kHz, air bone gap (ABG) gain groups. when ABG compared, significant decrease seen levels (p < 0.001). However, no difference = 0.608), which 10.1 7.00 dB group 10.8 5.38 group. groups, age, sex, the addition mastoidectomy procedure effect on success. Cartilage is a material may be preferred without concern about effects results, especially, values. impact outcome operation results. further studies larger case series carried out clarify issue.
