ABSTRACT

Objective: To identify secondary taste repercussions to manipulation of the chorda tympani in three different modalities in patients underwent to middle ear surgery via endomeatal.
Material and Method: A prospective, observational, longitudinal, and comparative study was done from January 2015 to January 2017 in patients underwent to otologic surgery via endomeatal, with otosclerosis and otitis media diagnosis and qualitative, quantitative, topographic, and concentration tests were practiced on them using four basic flavors (sodium chloride, sucrose, tantic acid, and tartaric acid) and the hilger facial nerve stimulator electric stimulator in the preoperative and postoperative period.
Results: There were included 101 patients grouped according the chorda tympani transoperative manage as follows: a) first instance section (n = 25), b) elongation (n = 26), and c) accidental section (n = 25). Qualitative alterations in salad, sweet and bitter flavors perception were observed; acid flavor remained with out changes. Major taste repercussions were observed in the chorda tympani accidental section treated group.
Conclusions: There are secondary taste alterations to the chorda tympani manipulation, principally on salad flavor, followed by sweet and bitter flavors. Acid flavor remained unaltered. Patients with chronic otitis media presented alterations in the perception of salad and sweet flavors since the preparatory evaluation. In our population, the best outcome related to taste modifications was with the transoperative management of chorda tympani with first instance section.
