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...

BACKGROUND Conventional low probe tone frequency tympanometry has not been successful in identifying middle ear effusion in newborn infants due to differences in the physiological properties of the middle ear in newborn infants and adults. With a rapid increase in newborn hearing screening programs, there is a need for a reliable test of middle ear function for the infant population. In recent ...

Abstract Background and Aims Many similarities exist between the nephron & ear infrastructures, making them vulnerable to same risk factors. Idiopathic sensory neural hearing loss is frequent in pediatric patients with chronic kidney disease (CKD). Our aims were determine prevalence, type, degree of impairment CKD patients. Method This cross-sectional study was carried out at dialysis nephr...

Tympanometry is a clinical measurement routinely included in the assessment of middle ear function. Despite its widespread use, however, fundamental questions remain regarding the need for age-dependent normative data. This study examines normal developmental changes associated with four tympanometric measurements: (1) ear canal volume, (2) peak compensated acoustic admittance, (3) tympanometri...
