Post-adenoidectomy reoperations due to obstructive adenoid hyperplasia

Abstract

Introduction: The incidence of post-adenoidectomy reoperation, be it a second ade- noidectomy or a tonsillectomy, is unknown within our environment. Foreign publications show a 2% of re-adenoidectomies and an 8% of ulterior tonsillectomies. Aim: To describe the adenoidectomies performed at our center, to assess the preva- lence of reoperations, and to seek possible associated factors to the latter. Material y method: Descriptive and analytical retrospective assessment. A review was per- formed of records for patients that between January of 1999 and December of 2010 underwent adenoidectomy on account of snoring pathology. Demographics, controls, nasopharyngolaryn- goscopies and reoperations (re-adenoidectomies and tonsillectomies) were recorded. Results: The review entailed checking 106 records. 55,7% of patients were men. 42% of patients had Parikh?s Grade III adenoids and 58% showed Grade IV ones. 5,6% of patients underwent reoperation. A significant difference could be observed in age (p=0,04) and tonsillar size (p=0,004) between those that had and had not undergone reoperation. There was no gender association (p=0,45), neither for asthma (p=0,31) or rhinitis (p=0,18). Yet, by multivariate logistic regression, no variable was significantly associated by itself to the need for reoperation. Conclusion: Reoperation prevalence was similar to that published, and no association to other factors was discovered.
