Evaluation of graft uptake in underlay myringoplasty using dry and wet temporalis fascia graft

Abstract

Chronic otitis media (COM) is a vital cause of deafness worldwide. Myringoplasty is one of the best treatment options for COM (inactive mucosal variety). Temporalis Fascia is the most favored grafting material among various autografts, which can be used as dry or wet depending upon the Surgeon's choice. The main focus of this study is to compare the graft uptake rate by using dry and wet temporalis fascia by underlay technique. This cross-sectional comparative study was directed from January 2018 to June 2019 at the Department of Otolaryngology-Head & Neck Surgery of BSMMU, Dhaka. All consecutive cases of COM (inactive mucosal) who underwent surgery were randomly assigned either into the dry (Group-A) or wet temporalis fascia group (Group-B). At 12 weeks follow-up, the density of graft failure (4.4% vs. 8.8%) and retraction pocket (0% vs. 2.2%) were higher in the wet procedure. However anterior blunting (2.2% vs. 2.2%) were the same in both procedures, and medialization (2.2% vs. 0%) were more in the dry procedure. Air Bone Gap (ABG) improved significantly in both groups following operation but reduced in Group-A more significantly than Group-B. On the other hand, there was no remarkable difference in successful graft uptake between the groups (Dry group-91.12% vs. wet group-84.44%, p>0.05). No graft material is superior to others in terms of graft uptake.
