Abstract

Background and aim: Tympanoplasty is a common surgery in otorhinolaryngology field. In majority of procedures, in addition to the graft used for closure of tympanic membrane, a packing material is essential to be placed in the middle ear cavity. The main goals of packing can be summarized as providing support to the tympanic membrane and ossicular grafts, aeration of middle ear cavity and hemostasis. Several packing materials are currently available for using in middle ear surgeries. Each agent is associated with particular advantages and disadvantages, so choosing the proper packing agent is essential in tympanoplasty surgeries. In this study we aimed to compare two common packing materials (Gelfoam and silastic sheets) in cartilage tympanoplasty surgeries. Methods and materials: In this block-randomized clinical trial, 78 patients undergoing tympanoplasty in Vali-e-asr hospital in 2017 and 2018 were enrolled. They were randomly assigned to silastic sheet or gelfoam groups. The functional outcomes were compared between the groups. Statistical analysis was performed by SPSS. Results: Success was achieved in 32 (82.1%) patients and 34 (87.2%) patients in gelfoam and silastic sheets' groups, respectively (p = 0.530). The perforation area percentage was significantly lower (P = 0.007) in Gelfoam group. The other parameters were statistically the same in both groups (P > 0.05). Conclusion: Overall, Gelfoam and silastic sheet methods had similar efficacy in cartilage tympanoplasty. Using each method depends on the preferrence of surgeon and patients' characteristics. Multi-center studies with larger sample sizes are needed for more conclusive results. © 2020
