Abstract

Background: Tympanoplasty has been well studied and shown to be effective. The purpose of our research was to assess the effectiveness of the superficial musculoaponeurotic system (SMAS) as a graft for tympanic membrane perforation, in contrast to the use of tragal perichondrium (TP).
Methods: This clinical prospective randomized trial was carried out on thirty individuals, their ages are between sixteen and fifty years old, with TMP, hearing loss gap not more than fifty, and dry ear (for at least one month) for trans-canal endoscopic type1 tympanoplasty. All patients were categorized randomly into two equally distinct SMAS graft groups: used SMAS as a graft, groups: TP graft group: used TP as a graft.
Results: Operation time was showing an important variance among both groups as a shorter time in TP group (P-value =0.009). The air conduction (AC) hearing thresholds at frequencies 500, 1000, and 2000 and air-bone gap (ABG) were recorded 3ms postoperatively. AC demonstrates important development at 500, 1000, and 2000 frequencies (P-value <0.001) at all frequencies, but no important variance between both groups. ABG and ABG gain demonstrate important variance and improvement of ABG in both groups among post and pre-operative (P-value=0.001) in both groups. No important variance in ABG and ABG gain between both groups.
Conclusions: SMAS graft in trans canal endoscopic type I tympanoplasty showed outcomes comparable to those achieved with TP. The use of the SMAS in endoscopic type 1 tympanoplasty was shown to be a safe, exhibiting no significant problems.
