Abstract
Adenoid is the condensation of lymphoid tissue at the back of the nose or on the posterosuperior wall of nasopharynx.Adenoid is the part of Waldeyer’s Ring . It appears to have an important role in the development of an (immunological memory) in children Adenoid hypertrophy occurs physiologically in children between the age of 6-10 years ,then atrophy at the age of 16 years.
Adenoid enlargement is un common in adults and because examination of the nasopharynx by indirect posterior rhinoscopy is in adequate ,many cases of enlarged adenoid in adult is misdiagnosed and accordingly maltreated.Presence of lymphoid hyperplasia in the adult nasopharynx ,including the persistence of childhood adenoid is associated with chronic inflammation.Regressed adenoidal tissue may re-proliferate in response to infections and irritants .
There is a wide choice of methods available to perform adenoidectomy. Routes for visualization and access to the adenoid may be transoral, transnasal or a combination. Combined method of conventional and endoscopic adenoidectomy allows the main bulk of the mass to be removed by adenoid curette and the remaining part under transnasal endoscopic control, using power shaver, suction cautery or sinus surgery forceps. The choanal location of the adenoid tissue cannot be visualized on plain lateral x-ray photos of nasopharynx but can be visualized by 1) sinoscopic evaluation. 2) CT nose and Para nasal sinuses.
