Résumé
Otitis media with effusion [OME] in Pakistani children is a controversial subject. Tympanometry and acoustic reflex test performed in 189 children of Baluchistan in the age range of 2-10 years has revealed 13.49% of the ears having type B [5.29%] and type C [8.20%] patterns suggestive of otitis media with effusion and Eustachian tube dysfunction. Preliminary otoscopy performed in 297 children revealed tympanic membrane with signs of middle ear effusion in 22.48% of the ears. Acoustic reflex response was absent in 18 [9.52%] of the ears. Abnormal middle ear pressure [MEP] in 42 [11.1%] and physical volume [PV] in 13 [4.3%] of the ears was observed. Prevalence of OME in children Baluchistan with its possible contributory factors are discussed
