The primary objective of this study was to identify factors predisposing for airway complications after reconstructive lower ja surgery. We reviewed records of patients undergoing mandibulectomy and microvascular bone reconstruction (N = 123). Epidemiological factors, modus of tracheotomy regarding ET and UT, postoperative ventilation time and occurrence of hospital-acquired pneumonia HAP were recorded. Predictors for PPV and HAP, ET and UT were identified. A total of 82 (66.7%) patients underwent tracheotomy of which 12 (14.6%) were performed as UT. A total of 52 (42.3%) patients presented PPV, while 19 (15.4%) developed HAP. Increased operation time (OR 1.004, p = 0.005) and a difficult airway (OR 2.869, p = 0.02) were predictors, while ET reduced incidence of PPV (OR 0.054, p = 0.006). A difficult airway (OR 4.711, p = 0.03) and postoperative delirium (OR 6.761, p = 0.01) increased UT performance. HAP increased with anesthesia induction time (OR 1.268, p = 0.001) and length in ICU (OR 1.039, p = 0.009) while decreasing in ET group (HR 0.32, p = 0.02). OR for ET increased with mounting CCI (OR 1.462, p = 0.002) and preoperative radiotherapy (OR 2.8, p = 0.018). ET should be strongly considered in patients with increased CCI, preoperative radiotherapy and prolonged operation time. ET shortened postoperative ventilation time and reduced HAP.<\/jats:p>","DOI":"10.3390\/jcm12030883","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T04:50:41Z","timestamp":1674449441000},"page":"883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Elective Tracheotomy in Patients Receiving Mandibular Reconstructions: Reduced Postoperative Ventilation Time and Lower Incidence of Hospital-Acquired Pneumonia"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3973-2474","authenticated-orcid":false,"given":"Johannes G.","family":"Schuderer","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonie","family":"Reider","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Wunschel","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0226-7580","authenticated-orcid":false,"given":"Gerrit","family":"Spanier","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steffen","family":"Spoerl","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maximilian Josef","family":"Gottsauner","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Maurer","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes K.","family":"Meier","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Kummer","sequence":"additional","affiliation":[{"name":"Section Phoniatrics and Pediatric Audiology, Department of Otolaryngology, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torsten E.","family":"Reichert","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Ettl","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital Regensburg, 93053 Regensburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"38","DOI":"10.1055\/s-0039-1677789","article-title":"Free-Flap Reconstruction of the Tongue","volume":"33","author":"Vincent","year":"2019","journal-title":"Semin.
