Background:
The effects of graft thickness on tympanoplasty is uncertain.
Objective:
To compare the results of endoscopic tympanoplasty using different thicknesses of autologous tissues.
Methods:
This retrospective analysis included 186 patients who received type I tympanoplasty, divided into three main groups based of grafting material: perichondrium (A), cartilage-perichondrium (B), or cartilage-perichondrium plus additional perichondrium (C). Group A was subdivided based on whether the placement was inside (A1) or outside (A2) of the malleus. The hearing improvement, graft success rate, and surgery duration were analysed.
Results:
Statistical analysis showed significant hearing improvement in the three main groups (p < .001); recovery in group A occurred the earliest. Six months postoperatively, group A1 showed significantly greater hearing recovery compared with groups B and C (p < .05). There were no statistical differences the other groups (p > .05) or in the graft success rate among the three main groups (p = .235). The surgery duration of group A was significantly longer than that of groups B and C (p < .001).
Conclusion And Significance:
Our results suggest that graft thickness affects hearing recovery; however, graft thickness does not affect the rate of grafting success. Endoscopic transplantation of the perichondrium is more difficult and requires more time.
