Abstract:
[Objective]To complete comparison between anterior cervical surgery by microendoscopic and open operation,explore feasibility and efficacy of anterior cervical decompression,interbody fusion and fixation by microendoscopic surgery,and give preliminary clinical evaluation of mieroendoscopic surgery.[Method]In a retrospective study,46 patients underwent one level cervical surgery by anterior approach.23 patients(23~64 years,41.5 years in average)were treated with microendoscopic surgery as microendoscopic group.Under general anesthesia,a transverse incision(1.6 cm)was made at right side of neck.A tubular retractor was then inserted and fixed,and a specially designed endoscope was placed inside the tubular retractor.Discectomy and interbody fusion with insertion of Cage or/and plate fixation was performed by endoscope.At fracture and dislocation patient group,titanium Cage was used in 1 case,CBK in 1 case,plate in 5 cases.At cervical disc herniation patient group,titanium Cage was used in 2 cases,CBK in 12 cases,plate in 2 cases.During the same period,23 patients(25~68 years,46.5 years in average)were treated with open surgery as open group.A transverse incision(4～5 cm)was made by right route approach.Discectomy and interbody fusion with Cage or/and plate fixation was performed by general procedure.[Result]At microendoscopic group,23 cases were followed up from 10 to 22 months(16.5 months in average),and mean operative time were 95 minutes,mean blood loss 90 ml.For fracture and dislocation patients,by Frankels classification,2 cases with complete tetraplegia showed no improvement,2 cases with incomplete tetraplegia improved from grade C to grade D postoperatively,1 case upgraded from C to E.For cervical spondylotic myelopathy patients with disc herniation,according to Odoms scoring system,10 cases had excellent outcome,5 good,1 fair.At open group,23 cases were followed up from 8~21 months(15.2 months as average),and mean operative time was 95 minutes,mean blood loss 90 ml.By Frankels classification,2 cases with complete tetraplegia had no improvement,3 cases with incomplete tetraplegia improved from C to D,1 case from D to E.According to Odoms scoring system,8 patients suffering from cervical spondylotic myelopathy with disc herniation had excellent result,6 good,2 fair.[Conclusion]Compared with open surgery,microendoscopic surgery with endoscopic instrument and technique can be used for one level discectomy,interbody fusion and internal fixation,and offer a similar short-term good clinical outcome with minimal incision,less traumatic reaction and postoperative discomfort.
