An Eight-Year Case ControlStudy Identifying Predictors of Adenoid Recurrence

Objectives: To determine the rate of revision adenoidectomy and to identify the risk factors associated with adenoid recurrence. In addition, we reviewed preoperative lateral neck x-Ray to see if adenoid size measurements could predict recurrence. Design: A 1:1 matched retrospective case-control study. Results: The rate of revision adenoidectomy was 2.74%.The mean age at first adenoidectomy was significantly lower in the revision adenoidectomy group. There was a strong association between adenoidectomy without tonsillectomy and repeated adenoidectomy. In addition, a diagnosis of OSA and other medical disorders including bronchial asthma and allergic rhinitis was a strong predictor of revision surgery. Hypertrophy of adenoid based on endoscopic examination indicates that patients with large adenoid size were more likely to require repeated procedure. Conclusion: We identified five risk factors for adenoid recurrence. Children younger than 5 years, patients with concurrent OSA, children who had undergone an adenoidectomy alone without tonsillectomy, concomitant diagnosis of medical disorders, and patients with large adenoid size on nasal endoscopy.
