Adenoidectomy: Selection Criteria for Surgical Cases of Otitis Media

Objective: Nasopharyngeal adenoids may serve as a mechanical obstruction to the eustachian tube and contribute to the pathophysiology of otitis media (OM). The purpose of this study was to determine whether abutment of adenoids laterally against the torus tubaris affects the outcome of patients requiring pressure equalization tubes (PET) for OM. Study Design: Randomized, controlled, prospective clinical trial. Method: Patients requiring PET for recurrent acute OM or OM with persistent effusion were randomized into two groups: 1) PET placement and 2) PET placement and adenoidectomy, regardless of whether the adenoids were abutting or not abutting the torus tubaris. Patients were followed for a minimum of 1 year to determine rate of treatment failure, defined as recurrence of acute OM (>3 times/year), OM with effusion, or reinsertion of PET. Results: Of the 34 patients in the abutting group, 16 patients underwent only PET insertion, of whom 8 (50%) failed, whereas 18 patients had combined PET placement and adenoidectomy, of whom 3 (17%) failed. There was a statistical difference between these two groups (P
