Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chorda tympani nerve (CTN), is a branch of nerve VII, and has two componants: taste sensation from the anterior two thirds of the tongue and salivary secretion from submandibular and sublingual salivary glands.

CTN go throw middle ear between malleus and incus. Due to it anatomic localization, CTN is frequently damage during otologic surgery.

Taste disturbance after middle ear surgery has been describe in literature but results of the various studies are very heterogenous. Moreover, there is no consensus to preserved or sacrificed a traumatize CTN.

We will use questionnaire to evaluate frequency, duration and characteristics of taste disturbance after ear surgery and the impact on the quality of life for those with symptoms.

We will evaluate the Influence of type of CTN injury on taste disturbance.
