Tympanometric gradient is a quantitative expression of the shape of a tympanogram in the vicinity of the peak. Previous work suggests that gradient measures may be diagnostically and prognostically useful in the assessment and management of middle ear disease. However, since almost all previous work on the subject was performed on tympanograms recorded in 'arbitrary compliance units' which are

Evaluation of tympanometric width, often termed tympanometric gradient, may supplement the use of static immittance ( Brooks, 1969; deJonge, 1983, 1986: Feldman et al., 1984: Koebsell & Margolis, 1986: Margolis & Heller, 1987: Paradise et al., 1976; Shanks & Wilson, 1986; Williams, 1976), Although not widely used clinically owing to a lack of normative data, tympanometric width has been shown to be …

Tympanometric width (also referred to as tympanometric gradient), refers to the width of tympanogram (in daPa) measured at one half the compensated static admittance (DeJonge, 1986; Koebsell & Margolis, 1986).

Tympanometric gradient




ABSTRACT . PURPOSE: To analyze and compare the tympanometric gradient and the compliance obtained in probe tones of 226 and 1 kHz between groups of infants with and without gastroesophageal reflux (GER). METHODS: Participants were 118 full-term and preterm infants, from newborns to 6-month-olds – 63 with clinical diagnosis of physiological GER performed by pediatricians or

Tympanometric gradients less than 0.2 are considered to be abnormally low (Nozza, Bluestone, Kardatzke, & Bachman 1992) and are associated with the presence of middle ear fluid (Brooks 1969; Paradise, Smith, & Bluestone 1976; Fiellau-Nikolajsen 1983; Nozza et al 1992).

Tympanometry is an acoustic evaluation used to evaluate the condition of the middle ear eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function.

Tympanometry is a test that measures the movement of your eardrum, or tympanic membrane. Along with other tests, it may help diagnose a middle ear problem.
