Application of the tragus cartilage ring with perichondrium for tympanoplasty in chronic otitis suppurative media in the period of infection / 中国组织工程研究

Recently, the annulus cartilaginous-perichondrium made from tragus cartilage-perichondrium were successfully used as grafts in open tympanoplasty and myringoplasty, which showed distinctly better effect than that of fascia temporalis with no drum retract or ossicular chain conglutination and stable hearing. The article retrospectively analyzed long term effect of 150 patients which received tragus cartilage ring with perichondrium as grafts in myringoplasties and mastoidectomy with ? period tympanoplasty, and summarized the superiority and application value of the tragus cartilage ring with perichondrium for tympanoplasty in chronic otitis suppurative media in the period of infection.

Diagnosis value of nasopharyngo-fiberscope and CT for microfocal nasopharyngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the value of nasopharyngo-fiberscope and CT in diagnosing microfocal Nasopharyngeal Carcinoma (NPC) and the prevalent area, the nasopharynx, where the NPC usually initially developed from.@*METHOD@#From October, 2003 to October,2005, the data of original microfocus of 36 pathologically confirmed NPC were reviewed retrospectively. These cases were examined by nasopharyngo-fiberscope and CT strengthening scanning.@*RESULT@#On clinical examination, only 2 cases (5.6%) were found to have original micro-tumor in the recess, the other 34 cases (94.4%) had developed from the other regions including 25 (69.4%) from the roof and 9 cases (25.0%) from the posterior wall, all with smooth and symmetrical mucosa in the recess. Positive rate of nasopharyngeal mass were 100% by nasopharyngo-fiberscope and by CT.@*CONCLUSION@#The data suggested that the roof of nasopharyngeal cavity be the most possible area that the original NPC micro-focus developed from, followed by the posterior wall and the recess. Nasopharyngo-fiberscope and CT is very helpful for the correct clinical diagnosis of NPC.

Study on the relationship between the assessment of facial muscle function and prognosis of Bell's palsy / 中国组织工程研究

BACKGROUND: There has been no definite cause for Bell's palsy. Different kinds of causes and courses always lead to different outcomes. Up to now there has not been to accord on the relationship between assessment of facial muscle function and prognosis of Bell's palsy.OBJECTIVE: To explore the relationship between level diagnosis, blink reflex(BR) , electroneurography(ENoG) and prognosis in order to find the timing for treatment of Bell's palsy.DESIGN: A self-control study.SETTING: Department of otolaryngology, Beihai People's Hospital,Guangxi Zhuang Autonomous Region.PARTICIPANTS: There were 42 cases of Bell's palsy that were in accordance with the diagnosis criteria and hospitalized in the Beihai People's Hospital from January 1989 to December 1999. Thirty-six cases out of the 42 were well documented and thus were studied here.METHODS: Level diagnosis, BR and EnoG test as well as facial muscle assessment were conducted on thirty-six patients with Bell's palsy.RESULTS: Patients with facial function score under 11 and with the lesion at D segment had poor results in BR and ENoG test. The outcome of conservative treatment for these patients was also bad. That would be improved by facial nerve decompression. The results of examination within one month after palsy onset were correlated with prognosis ( P ＞ 0. 05) . Two cases received decompression on the 40th day onset and recovered completely. Two cases Received decompression in the 2nd month, one recovered completely and decompression and recovered partially.CONCLUSION: Patients with the following manifestations may make conplete recovery after conservative treatment: lesion distal to segment D, facial function over 11 marks, presence of R1 wave by BR test in the 1st month and fiber deprivation ＜ 90% by ENoG. Facial nerve decompression should be taken for patients in a condition other than that.

CLINCAL RESEARCH ON TREATMENT OF VOCAL CORD LESION WITH LARYNGENDOSCOTIC SURGERY / 中国内镜杂志

Objective:To investigate the treatment efficient of vocal cord lesion with laryngendoscpic surgery.Methods:120 cases of vocal cord lesion were treated with laryngendoscpic surgery.The clinical data was analysised.Results:120 patients were operated after a month,82 cases (68.3%) were cured,32 cases (26.7%) improved,6 cases (5%) unimproved.These cases were followed up over a year.Results showed the 95 cases (72.9%) were cured,16 cases (13.3%) improved,9 cases (7.5%) unimproved.Conclusions:The approch to treatment of vocal cord lesion with laryngendoscopic under general anesthesia encheinesisless had a significant effect on treating vocal cord polypus and vocal nodules,and had fixed efficient on laryngeal Reinke's Oedem and vocal cysts as well.The authors believed that the limits of disease observation and same as have clinical value with laryngendscopic for cancer of the larynx and papilloma of the larynx.Microwaves tissue coagulation has tried out on treating cancer of the larynx and papilloma of the larynx.It's efficient need be observated at the same.
