OBJECTIVE To investigate the significance of diagnosis of tempanosclerosis by HRCT combined with pure tone audiometry. METHODS 176 patients(181 ears) with chronic suppurative otitis media in stationary phase were recruited in Guizhou Medical University Affiliated Hospital between January 2014 to December 2015. Temporal bone HRCT combined with pure tone audiometry were applied to all patients before operation to diagnose tempanosclerosis. Intraoperative exploration results was the gold standard to observe sensitivity, specificity, positive likelihood ratio and the difference of accuracy of two diagnostic methods. RESULTS 1. The sensitivity, specificity, positive likelihood, negative likelihood ratio and accuracy of tympanosclerosis diagnosed only by temporal bone HRCT were 58.55%, 93.10%, 8.49, 0.46 and 64.09% respectively. 2. The sensitivity, specificity, positive likelihood, negative likelihood ratio and accuracy of tympanosclerosis diagnosed by HRCT combined with pure tone audiometry were caculated as 94.08%, 89.66%, 9.09, 0.01 and 93.37% respectively. Type I diagnostic accordance rate was 89.66%, type II was 87.50%, type III was 84.62%and type IV was 82.14%. The total diagnosis coincidence rate was 86.18%. The diagnostic efficacy increased significantly by the combined method than by the temporal bone HRCT alone. CONCLUSION Temporal bone HRCT combined with pure tone audiometry is valuable in diagnosis of tympanosclerosis. It can provide theoretical basis for making optimal operation scheme in suspect tympanosclerosis patients.

OBJECTIVE: To describe tne regional different factors which impact on early cochlear implantation in prelingual deaf children between eastern and western regions of China. METHOD: The charts of 113 children who received the cochlear implantation after 24 months old were reviewed and analyzed. Forty-five of them came from the eastern region (Jiangsu, Zhejiang or Shanghai) while 68 of them came from the western region (Ningxia or Guizhou). Parental interviews were conducted to collect information regarding the factors that impact on early cochlear implantation. Result:Based on the univariate logistic regression analysis, the odds ratio (OR) value of universal newborn hearing screening (UNHS) was 5. 481, which indicated the correlation of UNHS with early cochlear implantation is significant. There was statistical difference between the 2 groups (P<0. 01). For the financial burden, the OR value was 3. 521(strong correlation) and there was statistical difference between the 2 groups (P<0. 01). For the communication barriers and community location, the OR value was 0. 566 and 1. 128 respectively, and there was no statistical difference between the 2 groups (P>0. 05). The multivariate analysis indicated that the UNHS and financial burden are statistically different between the eastern and western regions (P=0. 00 and 0. 040 respectively). CONCLUSION The UNHS and financial burden are statistically different between the eastern reinforced in the western region. In addition, the government and society should provide powerful policy and more financial support in the western region of China. The innovation of management system is also helpful to the early cochlear implantation.
