Effect of the use of dry (rigid) or wet (soft) temporal fascia graft on tympanoplasty.

摘要

OBJECTIVE: The aim of this study was to research the advantages and disadvantages of using a wet or dry temporalis fascia graft in myringoplasty surgery. STUDY DESIGN: Randomized prospective study. SETTING: Teaching and research hospital. METHODS: Dry graft was used in 210 cases, and wet graft was used in 174 cases in 384 patients who underwent tympanoplasty. OUTCOMES MEASURES: (1) Rate of primary closure of perforation, (2) rate of recurrent and residual perforation, (3) difference in hearing improvement between the two groups, (4) total operation time and graft placement time, and (5) histologic properties of wet and dry fascia grafts. RESULTS: The success rate was 91.4% (159 of 174) in the wet graft group and 88.6% (186 of 210) in the dry graft group. There were no differences between groups regarding recurrent disease, residual disease, and postoperative hearing results (p > .05). The mean operation time and graft placement time were shorter in group 2 (wet graft), and this difference was found to be statistically significant (p < .01). Histologically, the number of fibroblast nuclei was higher in group 2 (wet graft), and this was statistically significant (p < .01). CONCLUSION: The temporal fascia graft has a high success rate regardless of its use, either wet or dry. Using wet grafts can shorten the operation time and result in a high number of fibroblast nuclei histologically.
