Tympanometric changes following adenoidectomy in children with adenoid hypertrophy

Rashmi P. Rajashekhar, Vinod V. Shinde

Abstract


Background: Adenoid Hypertrophy is the commonest disorder in children. The size of adenoids varies from child to child and also in the same individual as he grows and attains maximum size between age of 3 to 7 years. Adenoid hypertrophy plays a significant role in the pathogenesis of otitis media with effusion. Our objective was to study the tympanogram changes following adenoidectomy. i.e to find out the effect  of  adenoidectomy on Otitis Media with Effusion.

Methods: Patients showing >50% of airway obstruction by the adenoids were included in the study. 20 patients with adenoid hypertrophy underwent adenoidectomy. Pre-operative and postoperative tympanograms of 40 ears were studied.  

Results: Type A curve (normal) was found in 12 ears. Type B Flat tympanogram – 12 ears s/o Gross Serous Otitis Media. Type C tympanogram – 8 ears s/o uncomplicated eustachian tube obstruction. 5 ears showed tympanogram s/o Eustachian tube block without significant collection of middle ear fluid. 3 ears showed tympanogram s/o uncomplicated eustachian tube obstruction. Post adenoidectomy, 32 ears showed normal tympanogram. 8 ears showed tympanogram s/o negative middle ear pressure with normal compliance.

Conclusions: Our study shows high prevalence of Otitis Media with Effusion in patients with adenoid hypertrophy. Otitis Media with Effusion is treated by adenoidectomy in most of the patients which is confirmed by post adenoidectomy tympanogram. Also, problem of decreased attention in school due to reduced hearing secondary to OME can be corrected by adenoidectomy. Hence, all patients should undergo pre and post-adenoidectomy tympanometry to know the compliance and pressure changes in the middle ear.
