Clinically, it is an effective alternative for use in nonintubated dental cases under total intravenous anesthesia. This technique can help improve oxygenation and ventilation in clinical situations in which the conventional use of NPAs is ineffective, such as in patients who have findings of obesity; mandibular retrognathia or hypoplasia; maxillary hypoplasia; macroglossia; nasal obstruction secondary to hypertrophic tonsillar, adenoid, and\/or lymphoid tissues or nasal polyps; known unusual nasal anatomy (eg, septal deviation); high risk of prolonged epistaxis (eg, patients on anticoagulants); or those who demonstrate mouth-breathing behaviors during deep sedation\/nonintubated general anesthesia. After ensuring proper supraglottic placement, the transorally positioned NPA can be further secured with the use of tape for the duration of the dental procedure. Unlike an oropharyngeal airway, this simple and cost-efficient technique facilitates intraoral access for dental treatment.<\/jats:p>","DOI":"10.2344\/anpr-66-03-04","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:40:56Z","timestamp":1584643256000},"page":"39-44","source":"Crossref","is-referenced-by-count":4,"title":["Alternative Transoral Application of Nasopharyngeal Airways"],"prefix":"10.2344","volume":"67","author":[{"given":"Robert","family":"Matsui","sequence":"first","affiliation":[{"name":"Dental Anesthesiology, Faculty of Dentistry, University of Toronto, Toronto, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle","family":"Wong","sequence":"additional","affiliation":[{"name":"Dental Anesthesiology, Faculty of Dentistry, University of Toronto, Toronto, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Waters","sequence":"additional","affiliation":[{"name":"Dental Anesthesiology, Faculty of Dentistry, University of Toronto, Toronto, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1191","reference":[{"key":"i0003-3006-67-1-39-b01","series-title":"Emerg Med J","doi-asserted-by":"publisher","first-page":"394","DOI":"10.1136\/emj.2004.021402","article-title":"The nasopharyngeal airway: dispelling myths and establishing the facts","volume":"22","author":"Roberts \n              K,","year":"2005","unstructured":"Roberts \n              K, \n            \n            \n              Whalley \n              H, \n            \n            \n              Bleetman \n              A. \n            \n          \n          The nasopharyngeal airway: dispelling myths and establishing the facts.
