Adenoid hypertrophy existence in adulthood- a truth revealed

Abstract

Background and aims: The adenoids (nasopharyngeal tonsils) are part of Waldeyer’s ring of lymphoid tissue. Endoscopic examination of the nasopharynx increasingly recognized that adenoidal tissue in adults is not an uncommon finding. The aims of this study were to determine prevalence of adult adenoid tissue and the possible reasons behind it. Methods: A retrospective study of 1,100 adult patients, who had routine nasal endoscopic examination for nasal obstruction and related pathologies, was undertaken. 84 cases with incidental hypertrophied adenoid were reviewed to determine the probable cause, presenting symptoms, clinical suspicion and final histological diagnosis. Results: The age of patients ranged from 18 years to 77 years. Median age was 32 years. 59 (70.24%) of adenoid hypertrophy patients were smokers and only 25 (29.76%) were nonsmokers suggesting strong association between smoking and adult adenoid hypertrophy with odds ratio=5.3251, %2value of 54.23 and an extremely significant p value. All the 84 cases were confirmed histopathologically as Reactive adenoid hyperplasia and no signs of malignancy in any of them. Conclusions: The true incidence of adenoidal hypertrophy in adults is unknown. Adenoidal tissue in adults, if present, must always be biopsied or removed irrespective of their macroscopic appearance. The result underlines the importance of considering adenoid hypertrophy as a cause or contributing factor in nasal obstruction and related pathologies in adults. It also supports the theory that it represents a long-standing inflammatory process rather than being a novel clinical entity.
