hearing status in neonatal hyperbilirubinemia by auditory brain stem evoked response and transient evoked otoacoustic emission
hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...
متن کاملAge and Gender Effects On Auditory Brain Stem Response (ABR)
Objectives: Auditory Brain Stem Response (ABR) is a result of eight nerve and brain stem nuclei stimulation. Several factors may affect the latencies, interpeak latencies and amplitudes in ABR especially sex and age. In this study, age and sex influence on ABR were studied. Methods: This study was performed on 120 cases (60 males and 60 females) at Akhavan rehabilitation center of university...
متن کاملCLINICAL CORRELATIONS BETWEEN AUDITORY BRAIN STEM RESPONSE AND MAGNETIC RESONANCE IMAGING IN PATIENTS WITH DEFINITE MULTIPLE SCLEROSIS
In an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (MS), an audiometric evaluation was performed and auditory brainstem responses (ABRs) were obtained. Stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of MS. 24 (RO%) patients had an abnormal ABR along with c...
متن کاملNeuromuscular choristoma of the internal auditory meatus.
Choristomas of the internal auditory meatus are exceedingly rare tumors. In most cases, neuromuscular choristomas have initially been misdiagnosed as vestibular schwannomas (VS). No known characteristics in the clinical presentation or in imaging exist distinguishing these tumors from VS, which are the most common tumors at this location [Smith et al.: AJNR Am J Neuroradiol 1997;18:327-329]. We...
متن کاملAngioleiomyoma of the internal auditory meatus: a rare occurrence in the internal auditory canal.
We describe a case of angioleiomyoma of the internal auditory meatus. A finding of this tumor at this site is very unusual. In fact, our review of the literature revealed that only 1 case has been previously reported. In our patient, the tumor was clinically and radiologically difficult to distinguish from an acoustic neuroma. It would be important to recognize this rare small tumor preoperativ...
