Aim: The present study is a prospective study that looks into the prevalence of chorda tympani nerve injury and related symptoms following varying degrees of trauma to the nerve during four common types of middle-ear operations; namely, Tympanomastoid operations, myringoplasty, Tympanoplasty and Exploratory tympanotomy. Materials and Methods: 178 patients who underwent middle ear cleft surgery were included in this prospective study. Childrens below 20 years and patients with other potential cause of taste disturbance were excluded. Patients were given a single questionnaire, so as to assess their post-operative taste disturbance. Patient name, Age, Sex, Type of middle ear surgery, side of surgery were recorded. Any change in sense of taste immediately (after 2-4 weeks) or delayed (2-3 years)were recorded. Results: The number of patients with Chorda tympani nerve-related symptoms varied widely between these four groups. Increased occurrence of the nerve related symptoms were observed in Tympanomastoid and Myringoplasty, and a prolonged recovery time were observed in the tympanomastoid group. Stretching of the nerve produced more symptomatic cases than thermal injury or drying. Conclusion: It is important to inform patients about the possibility of Chorda Tympani Nerve injury during middle-ear operations, and it should also be emphasized that symptoms related to Chorda Tympani Nerve injury can occur irrespective of the type of damage to the nerve.
