The cricoarytenoid relationship presented with spiral computed tomography was demonstrated and the reconstruction of arytenoid dislocation was presented by using multiplanar reconstruction algorithms. Fifteen patients with arytenoid dislocation documented by fiberoptic laryngoscopy and strobovideolaryngoscopy and 10 normal persons were displayed by spiral computed tomography (CT). A making design of our own had been used to diagnose arytenoid dislocation on axial CT image. Results showed that dislocation of cricoarytenoid joint was consistently demonstrated on several of the overlapping thin axial reconstructions in each of the 15 patients, in whom asymmetry of the bilateral cricoarytenoid joints was noted on axial images. It was found that on the glottic-fissure level the basal angle on abnormal side was larger in 8 patients than that on the normal side and smaller in 7 patients in patient group, whereas right basal angle was equal to the left in 8 subjects, except 2 in control group. There was statistically significant difference in the number of the equal to two basal angles of glottic fissure between control group and patient group (P<0.025). High-quality sagittal and coronal reconstructive images often were helpful in confirming or clarifying the complex arytenoid orientations. The findings that two-side basal angle was not equal in triangle of glottic fissure can be used as an objective parameter to diagnose arytenoid dislocation. Spiral CT is a useful adjunct in the diagnosis and treatment of dislocation of cricoarytenoid joint.

Clinical Observations on 109 Cases of Vocal Nodules Treated with Acupuncture and Chinese Drugs

引用

Journal of Traditional Chinese Medicine 2000年第3期20卷 202-205页

　　The treatment of vocal nodules with the combined use of needling on Kaiyin Yihao Xue (开音一号穴Kai Yin Point No. 1 for Voice-Regaining) and medicinal spray and tea made according to Xie Qiang’s empirical prescription, obtained a total effective rate of 93.6%, obviously superior to that of the group treated with western medicine and the group simply treated by Chinese drugs (P<0.01). This suggests that the combined use of acupuncture and Chinese drugs in the treatment of vocal nodules has better therapeutic effect and requires shorter course of treatment.

An Analysis of the Hoarse Speech Signals by the Three Mass Model of Vocal Cords *

引用

Journal of Southeast University(English Edition) 1998年第1期14卷 81-85页

作者：程启明陈雪丽万德钧东南大学仪器科学与工程系

A three mass model of vocal cords as well as mathematical expression of the model are discussed. Different kinds of typical hoarse speech due to laryngeal diseases are simulated on microcomputer and the effects of different pathological factors of vocal cords on model parameters are studied. Some typical spectrum distribution of the simulated speech signals are given. Moreover, hoarse speech signals of some typical cases are analyzed by the methods of digital signal processing, including FFT, LPC, Cepstrum technique, Pseudocolor encoding, etc. The experiment results show that the three mass model analysis of vocal cords is an efficient method for analysis of hoarse speech signals.
