Taste disorders after tonsillectomy: Case report and literature review

The authors describe a case of dysgeusia that occurred during the recovery period after a tonsillectomy. The cause was thought to be a lesion to the lingual branch of the glossopharyngeal nerve because of the location of the symptoms at the posterior region of the buccal cavity and because of the raised electrogustometric thresholds in the posterior region of one half of the tongue. Clarification of this type of case was made by a review of the literature from 1966 to June 2004, carried out with the aid of Medline. From a medicolegal standpoint, it is important to inform the patient of the risk of dysgeusia after tonsillectomy, especially if that patient has a profession in which taste plays an essential role.
