ABSTRACT Background: Adenoid is a nasopharyngeal tonsil becomes active between 3 to 7 years of age. Starts involution by adolescence. Few of the occasions, the adenoid persists causing various symptoms including ear, nose, throat and facial deformities. It is also important while addressing the cause for nasal obstruction due to the co-existent adenoid tissue which may fail to diagnose pre-operatively becomes an on-table surprise. Methods: Adult patients above 16 years are subjected to study. Routine clinical examination done followed by diagnostic nasal endoscopy and the size of the adenoid tissue and other associated findings are recorded. Results: 100 patients were included in the study and gradings were done. Conclusions: We conclude the presence of adenoid tissue is due to persistence of a childhood problem, which is supported by presence of associated findings like high arched palate, supernumerary teeth.
