Background And Objectives:
Myringoplasty is a surgical procedure performed to repair tympanic membrane perforation which can be performed either using a microscope or an endoscope. The aim of this study is to compare the graft uptake, hearing outcome and operative time of endoscopic myringoplasty (EM) versus microscopic myringoplasty (MM) by underlay cartilage island graft technique.
Subjects And Methods:
In this prospective comparative study of sixty patients divided into two equal groups with small to medium sized tympanic membrane perforation were included. Tragal cartilage was used as graft material. Both the groups underwent myringoplasty by underlay cartilage island graft using endoscope (n = 30) and microscope (n = 30). The study was conducted between February 2022 to May 2023 after taking ethical approval from IRC of Nepalese Army Institute of Health Sciences. All patients were followed up on 7th postoperative day (POD), 1 and 3 months after surgery.
Results:
Graft uptake in was 90 % (27/30) in MM group and 93.33 % (28/30) in EM group. Mean operating time was more in MM group (66.46 ± 6.78min) than EM group (64.53 ± 6.6 min). The improvement in Air Bone Gap (ABG) was better in EM group (12.46 ± 6.58 dB) compared to MM group (10.9 ± 9.01 dB). The differences in graft uptake, operating time and improvement in ABG were not statistically significant.
Conclusion:
The study concludes that it does not matter which approach is used, good results are predictable and choice of the tool used is up to the individual surgeon.
