[Radiographic evaluation of adenoidal-nasopharyngeal ratio in the children with otitis media with effusion]

ABSTRACT

Adenoid hypertrophy is one of the main common causes of eustachian tube dysfunction and otitis media with effusion. A group of otolaryngologists and pediatrics believe that it is not possible to estimate adenoid size in order to do Adenoidectomy only with clinical evaluation and there is no any acceptable result to show how many patients with OME were satisfied after adenoidectomy. The aim of this study is to determine ratio between adenoid and nasopharynx in children with adenoid hypertrophy and OME then determine the number of children who will be satisfy after adenoidectomy. This descriptive study was performed on 50 patients who had OME and adenoid hypertrophy and caome to ENT department of Imam Reza Hospital. The standard lateral neck view for the patients was done and sizes were calculated on lateral neck graphy. The A/N degree ratio which estimated was compared with the A/N degree ratio in normal children in the same ages from the other studies and the efficacy of adenoid size on obstructive manifestations was considered. 6 of 50 patients were between 4-6, 37 of them between 6-8 and, 7 of them between 8-10 years old. A/N ratio on different age groups in OME patients in comparison with normal people has no significant differences [P=0.43]. 16[%32] patients did not have any obstructive signs and 54[%44] had obstructive signs and mean ratio A/N was 0.44 and 0.49 respectively. This study shows in patients with OME, mean ratio A/N in a group with adenoid hypertrophy is higher than those in asymptomatic group [P<0.001]. This study shows in patients with OME and obstructive signs, adenoidectomy can be effective for the treatment of obstructive signs, but in patients with adenoid hypertrophy without obstructive signs, adenoidectomy would not be beneficial
