ABSTRACT
Objective To introduce the development of facial recess of 210 cases who recieved cochlear implantation and experienced the opening of the facial recess under the direction of high resolation computed tomography(HRCT).Methods The facial recess was assessed and measured using the HRCT before cochlear implantation in 210 patients who suffered from severe and profound sensorineural hearing loss.A statistic analysis was performed according to the age group,and the findings during the operation were compared with that before the surgery.Results The facial recess of 13 cases (6%) did not developed.The mean volume of the rest facial recess was 4.26 mm3 in 197 cases,while in 12.0 years group(group C) it was 3.09 mm3.The differences among three groups were statistically significant. The findings during the operation was agreed with the assessment results prior to the surgery.Conclusion 94% facial recesses developed in all 210 cases.Employment of HRCT scan prior to the surgery allows auurate determination of the location of facial recess to ensure successful surgery.
