Bony cochlear nerve canal stenosis and speech discrimination in pediatric unilateral hearing loss.
OBJECTIVES/HYPOTHESIS To examine the relationship between bony cochlear nerve canal (BCNC) width, degree of hearing loss, and speech discrimination in children with unilateral sensorineural hearing loss (USNHL). STUDY DESIGN Retrospective chart review (case-control study). METHODS Audiometric database was cross-referenced with radiologic database at pediatric tertiary care facility to ident...
متن کاملFacial nerve stimulation in the narrow bony cochlear nerve canal after cochlear implantation.
OBJECTIVES/HYPOTHESIS To evaluate the correlation between a narrow bony cochlear nerve canal (BCNC) and facial nerve stimulation (FNS) after cochlear implantation (CI) and their underlying mechanisms and to predict the risk of FNS preoperatively. STUDY DESIGN Retrospective cohort study. METHODS A total of 64 pediatric cases that underwent CI were included. Among them, 32 cases experienced F...
متن کاملA Case with the Bilateral Narrow Bony Cochlear Nerve Canals Associated with Near Normal Hearing Thresholds
The narrow bony cochlear nerve canal in high resolution temporal bone computed tomography is frequently found in patients of congenital sensorineural hearing loss. But this bony structural anomaly could not conclude the functional outcome of cochlear nerve. Here, we present a case of a 14-month-old girl having bilateral narrow bony cochlear nerve canals. In magnetic resonance imaging, both the ...
متن کاملClinical characteristics of patients with narrow bony cochlear nerve canal: is the bilateral case just a duplicate of the unilateral case?
OBJECTIVES/HYPOTHESIS To evaluate whether there is a genetic contribution to the development of narrow bony cochlear nerve canal and analyze the differences between unilateral and bilateral narrow bony cochlear nerve canal. STUDY DESIGN Retrospective review. METHODS Patients diagnosed with unilateral (n=44) or bilateral (n=13) sensorineural hearing loss with narrow bony cochlear nerve canal...
متن کاملAnomalous facial nerve canal with cochlear malformations.
BACKGROUND AND PURPOSE Anteromedial "migration" of the first segment of the facial nerve canal has been previously identified in a patient with a non-Mondini-type cochlear malformation. In this study, several patients with the same facial nerve canal anomaly were reviewed to assess for the association and type of cochlear malformation. METHODS CT scans of the temporal bone of 15 patients with...
