Methods: HMDRclin and HMDRecho were recorded the day before surgery in 160 consecutive consenting patients. Laryngoscopy was performed by a skilled anesthesiologist, with grades III and IV Cormack\u2013Lehane being considered difficult views of the glottis. Linear regression was used to assess the correlation between HMDRclin and HDMRecho and receiver operating curve analysis was used to compare the performance of the two for predicting difficult airway. Results: The linear correlation between HMDRclin and HDMRecho in patients without morbid obesity had a Pearson coefficient of 0.494, while for patients with morbid obesity this was 0.14. A slightly higher area under the curve for HMDRecho was oberved: 0.64 (5%CI 0.56\u20130.71) versus 0.52 (95%CI, 0.44\u20130.60) (p = 0.34). Conclusion: The association between HMDRclin and HDMRecho is moderate in patients without morbid obesity, but negligible in morbidly obese patients. These might be explained by difficulties in palpating anatomical structures of the airway.<\/jats:p>","DOI":"10.3390\/diagnostics10030140","type":"journal-article","created":{"date-parts":[[2020,3,3]],"date-time":"2020-03-03T13:06:23Z","timestamp":1583240783000},"page":"140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Clinical versus Ultrasound Measurements of Hyomental Distance Ratio for the Prediction of Difficult Airway in Patients with and without Morbid Obesity"],"prefix":"10.3390","volume":"10","author":[{"given":"Cristina","family":"Petri\u0219or","sequence":"first","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"},{"name":"Anaesthesia and Intensive Care 1, Clinical Emergency County Hospital Cluj-Napoca, 400006 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2455-9231","authenticated-orcid":false,"given":"Sebastian","family":"Tranc\u0103","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"},{"name":"Anaesthesia and Intensive Care 1, Clinical Emergency County Hospital Cluj-Napoca, 400006 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Szabo","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Simon","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Prie","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Constantin","family":"Bodolea","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care II, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, Clinical Emergency County Hospital of Cluj, 400006 Clinicilor 3-5, Cluj-Napoca, Romania"},{"name":"Anaesthesia and Intensive Care Department, Municipal Hospital Cluj-Napoca, 400139 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"493","DOI":"10.1001\/jama.2018.21413","article-title":"Will this patient be difficult to intubate? the rational clinical examination systematic review","volume":"321","author":"Det","year":"2019","journal-title":"JAMA"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"83","DOI":"10.11152\/mu-1764","article-title":"Preoperative difficult airway prediction using suprahyoid and infrahyoid ultrasonography derived measurements in anesthesiology","volume":"21","author":"Petrisor","year":"2019","journal-title":"Med.
