Abstract
Endoscopic microlaryngeal laser surgery performed with general anesthesia through a laryngoscope speculum generates heat that accumulates at the distal lumen, creating an "oven" effect and potentially causing bystander thermal damage to nontarget tissue such as the contralateral vocal fold. We report the effects of cooling on air and tissue temperatures that occurred during simulated laryngeal laser surgery with KTP and thulium lasers in an ex vivo calf model.

Laser energy was applied to one vocal fold for 2 minutes, with or without cooling, while temperatures were monitored with sensors placed within the glottal lumen or inserted superficially into the contralateral vocal fold. A pulsed KTP laser (525 mJ) was used for 5 larynges, and a thulium laser (7 W, continuous) was used for the other 5 larynges.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Heating was slightly greater for the KTP laser than for the thulium laser with use of these parameters. The lumen temperatures for both lasers increased an average of 13.2 degrees C without cooling, but only 6.7 degrees C with cooling (p < 0.05). The contralateral vocal fold (subepithelial space) temperature increased an average of 6.8 degrees C without cooling, but only 4.2 degrees C with cooling (p > 0.05).</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Cooling with room-temperature air during laryngeal laser surgery reduces luminal air and contralateral vocal fold temperatures. This effect is believed to be due to elimination of the plume of steam and smoke that significantly heats surrounding structures.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Burns</LastName><ForeName>James A</ForeName><Initials>JA</Initials><AffiliationInfo><Affiliation>Department of Surgery, Harvard Medical School, Boston, MA, USA.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Lopez-Guerra</LastName><ForeName>Gerardo</ForeName><Initials>G</Initials></Author><Author ValidYN="Y"><LastName>Heaton</LastName><ForeName>James T</ForeName><Initials>JT</Initials></Author><Author ValidYN="Y"><LastName>Kobler</LastName><ForeName>James B</ForeName><Initials>JB</Initials></Author><Author ValidYN="Y"><LastName>Kraas</LastName><ForeName>Julie</ForeName><Initials>J</Initials></Author><Author ValidYN="Y"><LastName>Zeitels</LastName><ForeName>Steven M</ForeName><Initials>SM</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Ann Otol Rhinol Laryngol</MedlineTA><NlmUniqueID>0407300</NlmUniqueID><ISSNLinking>0003-4894</ISSNLinking></MedlineJournalInfo><CitationSubset>AIM</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000818">Animals</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002417">Cattle</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005931">Glottis</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D007830">Larynx</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D053685">Laser Therapy</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000379">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D013696">Temperature</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014827">Vocal Cords</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000601">surgery</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2010</Year><Month>11</Month><Day>6</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2010</Year><Month>11</Month><Day>6</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2010</Year><Month>12</Month><Day>14</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">21049854</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
