Aim:
To report the clinical outcomes of microdiscectomy (MD) and endoscope assisted discectomy (EAD) techniques via the posterior approach in patients with cervical disc herniations (CDHs).
Material And Methods:
The data were obtained from retrospective review of the patient?s charts and the latest follow-up examination.
Results:
A total of 83 cases with CDH who were treated by posterior cervical discectomy (PCD), between 2010 and 2019, were reviewed. MD was used in 42 patients (male: 20, female: 22) with a mean age of 51.1 years. In MD group, all patients had pain, and 26 of them had additional weakness. Visual analogue scale (VAS) neck score was 7.72, VAS arm score was 8.83; PROLO score was 7.41. EAD was used in 41 patients (male: 26, female: 15) with a mean age of 38.7 years. In EAD group, all patients had pain, and 20 of them had additional weakness. VAS neck and arm scores were 7.75, and 8.72, respectively; PROLO score was 7.44. Mean follow-up time was 24.7 months. The scores at the latest exam are as follows: in MD group, VAS score for neck was 2.32, for arm 1.11; PROLO score was 9.58; in EAD group, VAS score for neck was 2.18 and for arm 0.97; PROLO score was 9.66. Both surgical techniques were success with statically significance (p?0.05) according to the scores.The techniques were equally effective while postoperative VAS (p > 0.412) and PROLO (p > 0.980) scores were similar in both groups.
Conclusion:
Both approaches are effective for selected patients with soft cervical disc herniation in which settled lateral location. Both techniques allow working with two handle, therefore facilitating the gentle manipulation that can obtain for avoiding hazardous effect to spinal cord and nerve root.
