Abstract
Minimizing collateral thermal damage during endoscopic laryngeal laser surgery remains a priority, and tissue cooling is one way to achieve this goal. Cooling systems utilizing compressed air have been shown to reduce the extent of thermal trauma on the vocal folds, but these units are not ideal for endoscopic applications because cooling is inefficient at the low airflows needed. We examined whether a novel vortex cooling device that generates cooled air at low flow rates would provide a cooling benefit beyond that which could be obtained by using room-temperature air for cooling tissue or by using no cooling during simulated laryngeal laser surgery.

Cooling was achieved with a prototype vortex cooler (9 degrees C air output; flow rate, 3 L/min), and tissue temperature measurements were compared to those with room-air cooling and no cooling. Thermal damage was analyzed histologically by measuring the depth of lactate dehydrogenase inactivation surrounding the mucosal incision. The cooling conditions were tested during time-constant cuts (8 seconds) and depth-constant cuts (into the thyroarytenoid muscle).</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">During time-constant cuts, comparison between vortex cooling and room-air cooling revealed that vortex cooling resulted in a thermal damage zone that was 14% smaller (519 versus 603 microm; p < 0.05). During depth-constant cuts, vortex cooling created a thermal damage zone that was 32% smaller than that created with no cooling (p <0.01) and 9% smaller than that created with room-air cooling (p < 0.01).</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Vortex cooling reduces thermal damage more effectively than room-air cooling or no cooling during both time-constant and depth-constant thulium laser cuts.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Koo</LastName><ForeName>Hae Jin</ForeName><Initials>HJ</Initials><AffiliationInfo><Affiliation>Department of Surgery, Harvard Medical School, and the Center for Laryngeal Surgery and Voice Rehabilitation, Massachusetts General Hospital, Boston, Massachusetts 02114, USA.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Burns</LastName><ForeName>James A</ForeName><Initials>JA</Initials></Author><Author ValidYN="Y"><LastName>Kobler</LastName><ForeName>James B</ForeName><Initials>JB</Initials></Author><Author ValidYN="Y"><LastName>Heaton</LastName><ForeName>James T</ForeName><Initials>JT</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></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Ann Otol Rhinol Laryngol</MedlineTA><NlmUniqueID>0407300</NlmUniqueID><ISSNLinking>0003-4894</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>8RKC5ATI4P</RegistryNumber><NameOfSubstance UI="D013932">Thulium</NameOfSubstance></Chemical></ChemicalList><CitationSubset>AIM</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000818">Animals</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002056">Burns</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000209">etiology</QualifierName><QualifierName MajorTopicYN="Y" UI="Q000473">pathology</QualifierName><QualifierName MajorTopicYN="Y" UI="Q000517">prevention & control</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002417">Cattle</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D003080">Cold Temperature</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005931">Glottis</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000473">pathology</QualifierName><QualifierName MajorTopicYN="N" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D007820">Laryngeal Mucosa</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000293">injuries</QualifierName><QualifierName MajorTopicYN="N" UI="Q000473">pathology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D007828">Laryngoscopy</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D007830">Larynx</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000473">pathology</QualifierName><QualifierName MajorTopicYN="N" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D053685">Laser Therapy</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000009">adverse effects</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D023421">Models, Animal</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D013932">Thulium</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014827">Vocal Cords</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000473">pathology</QualifierName><QualifierName MajorTopicYN="N" UI="Q000601">surgery</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2012</Year><Month>8</Month><Day>1</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2012</Year><Month>8</Month><Day>1</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2012</Year><Month>9</Month><Day>21</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">22844869</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
