There still is substantial disagreement on the actual prevalence of RLNP after ACDF as well as on risk factors for postoperative RLNP. The aim of this study was to describe the prevalence of postoperative RLNP in a cohort of consecutive cases of ACDF and to examine potential risk factors.<\/jats:p><jats:p>\n          Materials and Methods\u2003This retrospective study included patients who underwent ACDF between 2005 and 2019 at a single neurosurgical center. As part of clinical routine, RLNP was examined prior to and after surgery by independent otorhinolaryngologists using endoscopic laryngoscopy. As potential risk factors for postoperative RLNP, we examined patient's age, sex, body mass index, multilevel surgery, and the duration of surgery.<\/jats:p><jats:p>\n          Results\u2003214 consecutive cases were included. The prevalence of preoperative RLNP was 1.4% (3\/214) and the prevalence of postoperative RLNP was 9% (19\/211). The number of operated levels was 1 in 73.5% (155\/211), 2 in 24.2% (51\/211), and 3 or more in 2.4% (5\/211) of cases. Of all cases, 4.7% (10\/211) were repeat surgeries. There was no difference in the prevalence of RLNP between the primary surgery group (9.0%, 18\/183) versus the repeat surgery group (10.0%, 1\/10; p\u2009=\u20090.91). Also, there was no difference in any characteristics between subjects with postoperative RLNP compared with those without postoperative RLNP. We found no association between postoperative RLNP and patient\u2019s age, sex, body mass index, duration of surgery, or number of levels (odds ratios between 0.24 and 1.05; p values between 0.20 and 0.97).<\/jats:p><jats:p>\n          Conclusions\u2003In our cohort, the prevalence of postoperative RLNP after ACDF was 9.0%. The fact that none of the examined variables was associated with the occurrence of RLNP supports the view that postoperative RLNP may depend more on direct mechanical manipulation during surgery than on specific patient or surgical characteristics.<\/jats:p>","DOI":"10.1055\/s-0040-1710351","type":"journal-article","created":{"date-parts":[[2020,8,10]],"date-time":"2020-08-10T22:51:20Z","timestamp":1597099880000},"page":"508-512","source":"Crossref","is-referenced-by-count":9,"title":["Recurrent Laryngeal Nerve Palsy after Anterior Cervical Discectomy and Fusion \u2013 Prevalence and Risk Factors"],"prefix":"10.1055","volume":"81","author":[{"given":"Alina","family":"Huschbeck","sequence":"additional","affiliation":[{"name":"Brandenburg Medical School Fontane, Campus Bad Saarow, Bad Saarow, Germany"},{"name":"Department of Neurosurgery, Helios Clinic Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Knoop","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Helios Clinic Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian","family":"Gahleitner","sequence":"additional","affiliation":[{"name":"Brandenburg Medical School Fontane, Campus Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Koch","sequence":"additional","affiliation":[{"name":"Brandenburg Medical School Fontane, Campus Bad Saarow, Bad Saarow, Germany"},{"name":"Institute of Pathology, Helios Clinic Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Schrom","sequence":"additional","affiliation":[{"name":"Brandenburg Medical School Fontane, Campus Bad Saarow, Bad Saarow, Germany"},{"name":"Department of Otorhinolaryngology, Helios Clinic Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Stoffel","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Helios Clinic Krefeld, Krefeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex","family":"Alfieri","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Winterthur Cantonal Hospital, Wintherthur, Switzerland"},{"name":"Faculty of Health Sciences, Joint Faculty of the Brandenburg University of Technology Cottbus, Senftenberg, The Brandenburg Medical School Theodor Fontane, and the University of Potsdam, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julius","family":"Dengler","sequence":"additional","affiliation":[{"name":"Brandenburg Medical School Fontane, Campus Bad Saarow, Bad Saarow, Germany"},{"name":"Department of Neurosurgery, Helios Clinic Bad Saarow, Bad Saarow, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,8,10]]},"reference":[{"issue":"07","key":"ref1","first-page":"6","article-title":"Neurologic complications of anterior cervical discectomy in Louisiana","volume":"136","author":"T B Flynn","year":"1984","journal-title":"J La State Med Soc"},{"issue":"09","key":"ref2","doi-asserted-by":"crossref","first-page":"1467","DOI":"10.1097\/00005537-200009000-00011","article-title":"Vocal fold paralysis after anterior cervical spine surgery: incidence, mechanism, and prevention of injury","volume":"110","author":"M D Kriskovich","year":"2000","journal-title":"Laryngoscope"},{"issue":"22","key":"ref3","doi-asserted-by":"crossref","first-page":"2906","DOI":"10.1097\/00007632-200011150-00012","article-title":"On the incidence, cause, and prevention of recurrent laryngeal nerve palsies during anterior cervical spine surgery","volume":"25","author":"R I Apfelbaum","year":"2000","journal-title":"Spine"},{"issue":"01","key":"ref4","doi-asserted-by":"crossref","first-page":"53S","DOI":"10.1177\/2192568216687547","article-title":"Recurrent Laryngeal Nerve Palsy After Cervical Spine Surgery: A Multicenter AOSpine Clinical Research Network Study","volume":"7","author":"Z L Gokaslan","year":"2017","journal-title":"Global Spine J"},{"issue":"12","key":"ref5","doi-asserted-by":"crossref","first-page":"1833","DOI":"10.1007\/s00586-006-0069-0","article-title":"Intraoperative measurement of pharynx\/esophagus retraction during anterior cervical surgery.
