Abstract: Otitis media with effusion (OME) is difficult to detect because the symptoms and signs are not typical or even asymptomatic. Adenoid hypertrophy is an important cause of OME in children. There are many researches about relationship of adenoid hypertrophy and OME in children. Tympanogram width (Tw) has been known to be a sensitive parameter for diagnosis of OME.
Purpose: To understand the relationship of Tw and adenoid hypertrophy.
Method: This is an observational analytic study involving subjects with adenoid hypertrophy without OME who had underwent adenoid skull lateral X-Ray, nasoendoscopy, and tympanometry. Relationship of tympanometry parameters (Gr, Tw, Ytm, TPP, and Jerger type) with degree of adenoid hypertrophy measured with adenoid skull lateral X-Ray and nasoendoscopy was analyzed with Pearson and Spearman correlation test.
Result: There was significant correlation (p > 0,01) between Tw and degree of adenoid hypertrophy according to 3 adenoid skull lateral X-Ray measuring methods. There was no significant correlation between Ytm and Gr with degree of adenoid hypertrophy according to 3 adenoid skull lateral X-Ray measuring methods. There was also significant correlation (p > 0,05) between Tw and degree of adenoid hypertrophy measured with nasoendoscopy according to Parikh. There was no significant correlation between Gr, Ytm, TPP, and Jerger type with degree of adenoid hypertrophy measured with nasoendoscopy according to Parikh.
Conclusion: Tympanogram width correlates significantly with adenoid hypertrophy and has the potensial to predict occurance of OME.
