[Infectious mononucleosis: when is tonsillectomy indicated?].

INTRODUCTION

Infectious mononucleosis is usually a benign, self-limited disorder of the lymphopoietic system. Tonsillopharyngitis is a common presentation of the disease. Occasionally upper airway obstruction or a prolonged swallowing disorder require surgical intervention.

METHODS

We conducted a retrospective analysis of all infectious mononucleosis cases seen at the ENT clinic in St. Gallen, Switzerland, between 1994 and 1998.

RESULTS

21 records were analysed, among which 19 patients needed hospital care. 11 cases required tonsillectomy. The average duration of fever of the patients undergoing surgery was markedly lower (9 days) than the conservatively managed cases (14.2).

DISCUSSION: Tonsillectomy is well tolerated, eliminates airway obstruction and rapidly improves swallowing.
