Wideband Tympanometry

Wideband Tympanometry Normative Data for Turkish Young Adult Population.

OBJECTIVE The aim of this study was to obtain norm values for a young adult Turkish group and to investigate the differences between female and male subjects in terms of wideband tympanometry. MATERIALS AND METHODS One hundred ten young adult volunteers (mean±SD: 21.1±1.9 years) participated in this study. The measurements of wideband tympanometry were performed at octave frequencies between ...

Multifrequency tympanometry in infants

INTRODUCTION  The use of conventional tympanometry is not sufficiently sensitive to detect all cases of middle ear changes, and this hinders accurate diagnosis. OBJECTIVE  To characterize acoustic immittance measures of infants from 0 to 3 months of age using multifrequency tympanometry in a prospective study. METHOD  54 infants from 0 to 3 months of age were evaluated. The inclusion criter...

Tympanometry in Clinical Practice

Two “must read” articles on the development of clinical tympanometry are Terkildsen and Thomsen (1959) and Terkildsen and Scott-Nielsen (1960). Their interest in estimating middle-ear pressure and in measuring recruitment with the acoustic reflex had a profound effect on the development of clinical instruments. Each time I read these articles, I am struck first by the incredible amount of infor...

Tympanometry in Neonates- A Comparative Study

Objective: Impairment to hearing during childhood may lead to delay in the speech and language skills, making the communication process more difficult. Early identification and rehabilitation can benefit the children. It is necessary to test the hearing using accurate test procedures. Thus, aim of the study was to compare the use of probe tones (226Hz and 1000Hz probe tone) in tympanometry whil...
