The Mallampati classification was used to determine the relationship between tongue and palate. All patients performed the M\u00fcller maneuver in a sitting position. The Fujita classification was used to define the type of obstruction. All patients had polysomnography and were divided into 4 groups according to AHI. Statistical analysis was performed to evaluate the relationship between examination findings and AHI. &lt;i&gt;Results:&lt;\/i&gt; Of the patients, 133 (50.4%) were habitual snorers, 66 (25%) were mild OSA, 40 (15.2%) were moderate OSA and 25 (9.5%) were severe OSA patients. There was a positive correlation between neck circumference, BMI and AHI in males (p &lt; 0.001). There was a significant difference between patient groups according to Mallampati classification, collapse at the velopharyngeal level and hypopharyngeal level and Fujita classification (all p &lt; 0.001). There were significant relationships between tonsil size, Fujita classification, Mallampati classification, collapse ratios and AHI. &lt;i&gt;Conclusion:&lt;\/i&gt; We saw that hypopharyngeal area often contributes to obstruction and some examination methods correlate more with AHI. This can aid sleep physicians in the evaluation of OSA patients.<\/jats:p>","DOI":"10.1159\/000337134","type":"journal-article","created":{"date-parts":[[2012,4,18]],"date-time":"2012-04-18T07:46:27Z","timestamp":1334735187000},"page":"136-140","source":"Crossref","is-referenced-by-count":26,"title":["The Upper Airway Evaluation of Habitual Snorers and Obstructive Sleep Apnea Patients"],"prefix":"10.1159","volume":"74","author":[{"given":"Omer","family":"Karakoc","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timur","family":"Akcam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Gerek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hakan","family":"Genc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuat","family":"Ozgen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2012,4,5]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097%2F00005537-199912000-00002"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.93.4.678"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007%2Fs002689900506"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.123.4.1134"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.122.3.829"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097%2F00005537-200009000-00029"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1288%2F00005537-199511000-00021"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097%2F00005537-200306000-00011"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1007%2FBF03011357"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1097%2F00005537-200011000-00010"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1080%2F00016480050218753"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1288%2F00005537-198512000-00009"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1288%2F00005537-198907000-00002"}],"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/337134","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/337134","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T19:12:11Z","timestamp":1745435531000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000337134"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":13,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2012,6,1]]},"published-print":{"date-parts":[[2012,6,15]]}},"URL":"https:\/\/doi.org\/10.1159\/000337134","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
