Objectives. The goals of the study were to compare the middle ear (ME) volumes from both normal and lesioned ears, and
these ME volumes were measured by a digital image processing computed tomography (CT) program in patients with
unilateral chronic otitis media, and we wanted to compare the ME volumes of the lesioned ears by comparing the ME
volumes obtained by tympanometry with those ME volumes measured by the digital image processing CT program.
Methods. Forty-four patients who had unilateral chronic otitis media (COM) and contralateral normal tympanic membranes
(TM) and 100 subjects with normal TMs were included in the study. The normal volumes of the external auditory
canal (EAC) were measured in the normal group. The tympanometric ME volumes in the ears with a perforated TM
were calculated as the difference of the tympanometric volumes measured from the both ears in patients with unilateral
COM. The CT ME volumes were measured by a digital image processing program.
Results. The tympanometric volumes of the EACs in the ears with normal TMs were 1.4±0.3 mL. There were no significant
differences according to gender, age and the side of the face the ear was on. The tympanometric volumes of the EAC
in the normal-side ear of the patients with unilateral COM showed no significant differences when compared with those
from the normal group. The ME volumes of the intact ears, as measured by CT, showed significantly higher values than
those ME volumes of the lesioned ears. The ME volumes of the lesioned ears, as measured by tympanometry, showed
a strong, significant linear correlation with those ME volumes calculated by CT; however, the ME volumes of the lesioned
ears, as measured by tympanometry (1.5±1.4 mL), were significantly larger than those ME volumes measured by CT
(1.1±0.8 mL).
Conclusion. Our results show that chronic otitis media causes reduced ME volumes compared to those ME volumes of the
contralateral normal ears. Tympanometry can provide a valuable estimation of the ME volumes in chronic ears, although
it tends to overestimate the ME volumes, and especially for the ears with a larger ME volume.
