Although PSTS peaks at day 2 or 3 after ACDF, with swelling noted to be prominent at the C2\u2013C4 levels, the way in which the features of PSTS vary according to surgical level has not been examined.<\/jats:p><jats:p>Thirty-seven patients who underwent one-level ACDF were reviewed and classified into retropharyngeal and retrotracheal groups based on surgical level. PSTS occurring at C2\u2013C6 and the width of the airway (WA) at C2\u2013C4 were assessed using plain radiographs before surgery and at 1, 3, 5, and 7 days postoperatively.<\/jats:p><jats:p>The retropharyngeal group comprised 10 patients, while the retrotracheal group comprised 27 patients. The retropharyngeal group had the most severe PSTS on day 3 after surgery. C4 showed PSTS peaked on day 3, with a value of 3.26 times the preoperative prevertebral tissue thickness. The WA at C4 was narrowest on day 1, with a value of 0.74 times and remained narrow until day 3. The retrotracheal group showed the most severe PSTS on day 1 at the C3 level: 2.81 times. The WA at C4 was narrowest on day 1 with a value of 0.78 times and increased thereafter.<\/jats:p><jats:p>PSTS following one-level ACDF for both retropharyngeal and retrotracheal lesions was greatest at the C3 and C4 levels, with peaks on the third day after operation for the former and the first day for the latter. The WA at C4 was narrowest from day 1 in both groups. In the retropharyngeal group, narrowing remained until day 3.<\/jats:p>","DOI":"10.1055\/a-2389-5283","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T19:41:41Z","timestamp":1723837301000},"page":"453-458","source":"Crossref","is-referenced-by-count":0,"title":["Prevertebral Soft-Tissue Swelling Following One-Level Anterior Cervical Diskectomy and Fusion: An Analysis Based on Surgical Level"],"prefix":"10.1055","volume":"86","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6390-2330","authenticated-orcid":false,"given":"Ryo","family":"Kanematsu","sequence":"additional","affiliation":[{"name":"Fujieda Heisei Memorial Hospital - Spinal Disorders Center, Shizuoka, Fujieda, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiyuki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Fujieda Heisei Memorial Hospital - Spinal Disorders Center, Shizuoka, Fujieda, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manabu","family":"Minami","sequence":"additional","affiliation":[{"name":"Fujieda Heisei Memorial Hospital - Spinal Disorders Center, Shizuoka, Fujieda, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junya","family":"Hanakita","sequence":"additional","affiliation":[{"name":"Fujieda Heisei Memorial Hospital - Spinal Disorders Center, Shizuoka, Fujieda, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,6,9]]},"reference":[{"issue":"09","key":"ref1","doi-asserted-by":"crossref","first-page":"949","DOI":"10.1097\/00007632-200205010-00013","article-title":"Airway complications associated with surgery on the anterior cervical spine","volume":"27","author":"H C Sagi","year":"2002","journal-title":"Spine"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"424","DOI":"10.1093\/neurosurgery\/23.CN_suppl_1.424","article-title":"Complications of surgery of the anterior cervical spine","volume":"23","author":"J M Tew Jr","year":"1976","journal-title":"Clin Neurosurg"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1007\/BF01407775","article-title":"Complications of anterior cervical discectomy without fusion in 450 consecutive patients","volume":"99","author":"H Bertalanffy","year":"1989","journal-title":"Acta Neurochir (Wien)"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"544","DOI":"10.2106\/00004623-199173040-00011","article-title":"Upper-airway obstruction after multilevel cervical corpectomy for myelopathy","volume":"73","author":"S E Emery","year":"1991","journal-title":"J Bone Joint Surg Am"},{"issue":"01","key":"ref5","first-page":"12","article-title":"Results and risk factors for anterior cervicothoracic junction surgery","volume":"94","author":"J A Boockvar","year":"2001","journal-title":"J Neurosurg"},{"issue":"18","key":"ref6","doi-asserted-by":"crossref","first-page":"2188","DOI":"10.1097\/00007632-199709150-00019","article-title":"Severe angioedema causing airway obstruction after anterior cervical surgery","volume":"22","author":"M J Krnacik","year":"1997","journal-title":"Spine"},{"issue":"03","key":"ref7","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1177\/0310057X9802600314","article-title":"Recurrent acute upper airway obstruction after anterior cervical fusion","volume":"26","author":"A Penberthy","year":"1998","journal-title":"Anaesth Intensive Care"},{"issue":"22","key":"ref8","doi-asserted-by":"crossref","first-page":"2404","DOI":"10.1097\/00007632-199911150-00019","article-title":"Complications of buttress plate stabilization of cervical corpectomy","volume":"24","author":"K D Riew","year":"1999","journal-title":"Spine"},{"issue":"04","key":"ref9","doi-asserted-by":"crossref","first-page":"290","DOI":"10.1007\/s00264-005-0072-9","article-title":"Prevertebral soft tissue swelling after anterior cervical discectomy and fusion with plate fixation","volume":"30","author":"K S Suk","year":"2006","journal-title":"Int Orthop"},{"issue":"01","key":"ref10","doi-asserted-by":"crossref","first-page":"77","DOI":"10.4055\/cios.2012.4.1.77","article-title":"Efficacy of postoperative radiograph for evaluating the prevertebral soft tissue swelling after anterior cervical discectomy and fusion","volume":"4","author":"K J Song","year":"2012","journal-title":"Clin Orthop Surg"},{"issue":"06","key":"ref11","doi-asserted-by":"crossref","first-page":"602","DOI":"10.3171\/jns.1958.15.6.0602","article-title":"The anterior approach for removal of ruptured cervical disks","volume":"15","author":"R B Cloward","year":"1958","journal-title":"J Neurosurg"},{"key":"ref12","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1007\/BF01406047","article-title":"Treatment of cervical disc disease using Cloward's technique.
