Clinical Analysis of 112 Cases of Vertigo Associated with Changes of Head Position / 听力学及言语疾病杂志

Objective To investigate the diagnosis and treatment of vertigo associated with changes of head position.Methods 112 patients of vertigo associated with changes of head position were analyzed from June 2006 to December 2007 through the positional tests and imaging examination.Results 45 men and 67 women from ages 12 to 75 (median 50) were included with a total of 112 patients.88 patients were diagnosed as benign paroxysmal positional vertigo(BPPV),76 patients as posterior semicircular canals BPPV,9 patients as horizontal semicircular canal BPPV,3 patients as anterior semicircular canals BPPV,9 patients as suspicious BPPV.They were treated by canalith repositioning procedure,the total improvement rate was 96.9% after 1 week.15 cases of cervical vertigo were treated by physical therapy and medication,the vertigo of 4 patients disappeared and of 11 patients was improved significantly after 2 weeks.Conclusion The positional tests and cervical plain x-ray are the simplest ways to diagnose vertigo associated with changes of head position.Physical therapy and medication are effective.It is suitable to promote in the grass-roots hospitals.

The diagnostic value of high resolution CT in assessment of temporal bone traumatic facial nerve paralysis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the diagnostic value of high resolution CT for temporal bone traumatic facial nerve paralysis and the guidance significance for surgery.@*METHOD@#Twenty-nine patients of traumatic facial nerve paralysis were investigated. The predictive diagnosis was made according to the clinical data and the image features of HRCT, then a comparative analysis of the preoperative image features and the surgical findings were carried out.@*RESULT@#The trend of temporal bone fracture displayed on the CT scan was basically consisted with the surgical findings. The direct CT signs of facial nerve injury include the bone fracture line went through the tube, bone tube rupture or continuity interruption, while the indirect CT signs include local incrassation of the facial nerve, lower bone density of the tube, geniculate fossa expansion, oppressed facial nerve, et al. The predictive diagnostic accordance rates of all the image features were above 90% as to the surgical findings.@*CONCLUSION@#High resolution CT could localize the trend of temporal bone fracture,and is helpful to estimate the extent of facial nerve injury and other complications. High resolution CT could provide reliable basis for clinical diagnosis and treatment.
