Aim: To evaluate the intraoperative fallopian canal dehiscence in chronic otitis media. Material and methods: This research was conducted over the course of one year in a hospital setting, namely in the department of otorhinolaryngology. The research included a cohort of 60 individuals with Chronic otitis media who met the specified criteria and received surgical intervention. This research included all patients with chronic otitis media who expressed their willingness to provide permission. individuals with chronic otitis media who refuse to provide permission for participation in the trial, as well as individuals with ear tumours, are excluded. Results: Prevalence of Dehiscent facial nerve was seen in 20 out of 60 patients accounting for 33.33%. Out of the 20 patients with dehiscence, maximum number of dehiscences were of 2-4mm dimension. Followed by those of length <2mm and >4mm in no specific order. Out of the 20 patients with dehiscence, maximum 15(75%) of dehiscences have Duration of ear discharge ≥ 10 years and 5(25%) of dehiscences have Duration of discharge < 10 years. Conclusion: The prevalence of fallopian canal dehiscence in otologic surgery exhibits significant variability. The site of fallopian canal dehiscence caused by cholesteatoma is similar to the typical places where the facial nerve is often injured, such as the tympanic part. The surgeon should be aware that doing surgery in the middle ear has the potential to cause stress or harm to the facial nerve near the location of the fallopian canal dehiscence.
