Effect of perinatal biotin deficiency on auditory pathway of the Wistar-Albino rats.

Severe biotin deficiency associated with biotinidase enzyme deficiency in newborns is seen as severe neurological problems and hearing loss. However, the effect on the infant of deficiencies in the maternal diet during pregnancy are not clear. The study included 16 female Wistar albino rats and 4 male Wistar albino rats, that were mated and then the females were separated into 4 groups.

Sensorineural hearing loss in β-thalassemia patients treated with iron chelation.

The predictive value of pure-tone audiometry (PTA) in the early detection of ototoxicity has been questioned, particularly in the higher frequencies. Otoacoustic emissions testing appears to be more sensitive to cochlear insult than conventional PTA. We conducted a cross-sectional descriptive study to compare the efficacy of distortion-product otoacoustic emissions (DPOAE) testing with that of PTA as a method of audiologic monitoring.

[The effect of operation success on middle ear ventilation in patients with nasal septal deviation].

Objectives: This study aims to evaluate the effect of septal deviation causing nasal obstruction and septal surgery on middle ear ventilation.

Patients And Methods: Twenty-five patients over 18 years of age (6 females, 19 males; mean age 24.7±6.

Comparison of pure tone audiometry and auditory steady-state responses in subjects with normal hearing and hearing loss.

The objective of this study is to compare pure tone audiometry and auditory steady-state response (ASSR) thresholds in normal hearing (NH) subjects and subjects with hearing loss. This study involved 23 NH adults and 38 adults with hearing loss (HI). After detection of behavioral thresholds (BHT) with pure tone audiometry, each subject was tested for ASSR responses in the same day.
