چکیده
Introduction: The aim of this study was to evaluate the width bony cochlear nerve canal (BCNC) in children with congenital sensorineural hearing loss (SNHL) and "normal" findings on thin section temporal bone CT. Material methods: BCNC retrospectively evaluated two groups patients. group included 11 (22 canals) aged 2-12 years, congenital, bilateral SNHL who underwent implantation (CI) from July December 2019 no abnormalities inner ear were detected their preoperative CT scans. Eleven patients canals), 3-10 whom had been diagnosed taken as controls scan performed for another reason - suspected acute mastoiditis, chronic otitis media, or perforation tympanic membrane. Axial sections scans used measure BCNC. Results: values bilateral, profound ranged 1.0 2.3 mm mean value 1.5±0.3 mm. In normal hearing, higher, 2.1±0.3 Conclusion: results obtained showed that impairment significantly smaller than control p <0.05 (t-test=6.62912, p=0.000000).

متن کاملSegregation of DFNB49 with congenital sensorineural bilateral profound hearing loss
Deafness is a complete or partial loss of hearing. In Pakistan, the prevalence of this order is high as compared to the other countries because of frequent consanguineous marriages in Pakistan. During present study, DFNB49 was mapped in two unrelated consanguineous families having multiple affected individuals. The maximum LOD score was found 4.71 and 2.74 for PKDF1069 & PKDF751 respectively. T...
