Comparative analysis between three lines reduce tension septorhinoplasty and nasal septum submucous resection / 中国基层医药

Objective To evaluate the advantages of nasal septum deviation with three lines reduce tension septorhinoplasty under endoscopy.Methods Three lines reduce tension septorhinoplasty of 48 cases were compared with nasal septum submucous resection(Killian) of 43 cases.Results Followed-up for 3 months to 1 year postoperation,study group were remedied and no clinical symptoms,no complications,control group had septal perforation of 1 case,nasal synechia of 2 cases,saddle nose of 1 case.The incidence of two groups postoperative complications had statistically significant difference.Conclusion Compared with Killian,three lines reduce tension septorhinoplasty was easy to stuty and have the advantages of micro-invasion,safety and efficiency,and was favorable recovery nasal cavitysinuses physiological functions.

AN INIMAL EXPERIMENT OF A NEW TECHNIGUE OF MACROSCOPIC VASOVASOSTOMY WITH CATGUT TO SPLINT AND REDUCE TENSION AND SUTURING TUNIC OF THE BOTH ENDS OF THE VAS / 重庆医科大学学报

A new technigue of the macroscopic vasovasostomy has been reported. The procedure was carried out by suturing only tunic of the both ends of the vas with catgut to splint and reduce tension(Group 1 ).In animal experiment, this technigue was compared with following methods of vasovasostomy. ( 1 ) .tunic-muscular layer anastomosis without splint(Group 2),(2).whole layer anastomosis with stainless steel splint (Group 3) and (3).whole layer anastomosis without splint. Among all dogs,the operative procedure was performed without the aid of optical magnification nor any special instruments. The four technigues were tested in 60 dogs (120 vasa) in which each of them used 15 dogs (30 vasa). The results of the dog experiments showed that the anatomical patency rates of the Group 1,2,3 and 4 after operation were 63.3%, 66.7%, 23.3%and 10%.Our studies indicate that the use of absorble catgut as an intravasal splinting and reducing tension in vasovasostomy is feasible in dogs.Gross as well as microscopic evaluation of the anastomotic area demonstrated that the intraluminal material was substantially absorbed with nosignificant reaction after operation.As compared with other macroscopic vasovasostomies, this technic is claimed to be simpler, easier, less traumatic, effective and feasible
