Materials and Methods: Nineteen consecutive patients with CS who needed surgical intervention were recruited. All enrolled patients underwent unilateral biportal endoscopic laminectomy (UBEL). All patients were followed postoperatively for &gt;1 year. The preoperative and final follow-up evaluations included the Japanese Orthopedic Association (JOA) score for neurological assessment, visual analogue scale (VAS) for axial pain and C2\u2013C7 Cobb angle for cervical sagittal alignment. The postoperative complications were analyzed. Results: Thirteen males and six females were included in the analysis. The mean follow-up period was 16.3 \u00b1 2.6 months. The mean operative time was 82.6 \u00b1 18.4 min. Postoperative MRI and CT revealed ideal neural decompression of the treated segments in all patients. Preoperative VAS and JOA scores improved significantly after the surgery, and cervical lordosis was preserved on the postoperative images. Conclusions: UBEL was an effective surgical method for CS, which may also minimize iatrogenic damage to the posterior tension band (PTB) and help to maximize the preservation of the cervical lordosis.<\/jats:p>","DOI":"10.3390\/medicina59020305","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T03:01:45Z","timestamp":1675825305000},"page":"305","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Unilateral Biportal Endoscopic Laminectomy for Treating Cervical Stenosis: A Technical Note and Preliminary Results"],"prefix":"10.3390","volume":"59","author":[{"given":"Chengyue","family":"Zhu","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xizhuo","family":"Zhou","sequence":"additional","affiliation":[{"name":"Hangzhou School of Clinical Medicine, Zhejiang Chinese Medical University, Binwen Road NO 548, Hangzhou 310053, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guofen","family":"Ge","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cuijuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoshan","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Dingqiao Hospital, Huanding Road NO 1630, Hangzhou 310021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6267-8819","authenticated-orcid":false,"given":"Dong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Dingqiao Hospital, Huanding Road NO 1630, Hangzhou 310021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hang","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University, Tiyuchang Road NO 453, Hangzhou 310007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"761","DOI":"10.1007\/s00264-018-4221-3","article-title":"Cervical disc herniation: Which surgery?","volume":"43","author":"Mazas","year":"2019","journal-title":"Int.
