Abstract

Background 

Tympanometry is the objective dynamic measurement of acoustic admittance of the middle ear cleft as a function of changes in air pressure in the external ear canal. Tympanometric width (TW) is the width of the tympanogram in daPa measured at half of the height from the peak to tail specify that the tail value is to be estimated from the tympanogram at +200 daPa.

Objectives 

To evaluate the normal TW in the Sulaymaniyah governorate.

Materials and Methods

It is a prospective comparative clinical study undertaken in Kurdistan audiology center & pediatric teaching hospital in Sulaymaniyah governorate. Tympanometry test utilized for normal hearing participants after exclusion associated ear diseases. The clients were included after taken informed consent, divided into two groups according to their age, group A; age (2-7) years, group B; age (8-60) years. Then the clinical data retrieved from the tympanogram results and statistical analysis were done.

Results

268 patients of either sex (128 males & 140 females) included in the study, there were higher width values in (2-7 years) age group in comparison with (8-20 years) age group with a p < 0.001, which is statistically significant. 

Conclusion

The data generated in this study provide the beginnings of a normal database for the Sulaymaniyah governate population. TW 210 daPa and 175 daPa in normal population age groups of (2-7 years) and (8-60 years) respectively, considered as abnormal. Although there were no interaural or gender differences in TW, further future work in all age levels is advocated.
