Tonsillectomy may cause altered tongue sensation in adult patients

Abstract

Objectives:

To determine the frequency of altered tongue sensation following tonsillectomy, and its relationship to different surgical techniques.

Design:

Case–control study.

Setting:

District general hospital.

Participants:

One hundred and four consecutive adults undergoing tonsillectomy, and 43 control patients.

Main outcome measures:

Altered tongue sensation.

Results:

Twenty-eight of 100 patients described altered tongue sensation post-tonsillectomy. No patients in the control group experienced altered tongue sensation. There was a difference in rates of altered sensation between tonsillectomy patient groups undergoing bipolar diathermy and ‘cold steel’ techniques (p < 0.019). Three months after surgery, 22/23 contactable patients reported complete recovery of tongue sensation. One patient experienced tongue paraesthesia persisting until one year post-tonsillectomy.

Conclusion:

Tonsillectomy resulted in altered tongue sensation in 28 per cent of our study group. Bipolar diathermy dissection was significantly more likely to cause altered sensation than cold steel dissection. Ninety-six per cent of these disturbances resolved by three months, all by one year. Possible alteration of tongue sensation should be discussed whilst obtaining consent for tonsillectomy.
