Resumo: The difficulty in visualizing the maxillary sinus ostium (MSO), even with angled optics, may result in the lack of inclusion of the ostium, an important cause of failure in endoscopic sinus surgery. As such, an anatomical landmark to locate the ostium could reduce residual or recurrent disease. The M line is an imaginary horizontal marker, parallel to the nasal cavity floor, extending from the lower portion of the ethmoidal bulla to the uncinate process. This study aimed to determine if the M line can identify the MSO during endoscopic sinus surgery. Dissections were performed in 57 cadavers (n=114) and 73 computed tomography scans (n=146) of patients with chronic rhinitis or rhinosinusitis were examined. Next, the M line was applied in the endoscopic sinus surgery of five patients. It crossed the MSO in 112 dissected sides (98%) and 140 sides on computed tomography scans (96%) and was used to identify the MSO in all operated patients, without complications during or after surgery. The M line is an anatomical landmark that indicates the location of the MSO and could therefore help endoscopic sinus surgery be more effective, safe and minimally invasive.

Portanto, um marcador anatômico para localizar o óstio pode reduzir a taxa de doença residual e recorrente. A linha M é uma linha imaginária horizontal, paralela ao assoalho da cavidade nasal, que se estende da porção mais inferior da bula etmoidal até o processo uncinado. O estudo tem como objetivo avaliar se a linha M é um marcador anatômico capaz de localizar o OSM na cirurgia endoscópica nasal. Realizou-se um estudo anatômico com 57 cadáveres (n=114) e radiográfico com 73 tomografias computadorizadas dos seios paranasais de pacientes com rinite ou rinossinusite crônica (n=146). Em seguida, aplicou-se na linha M durante a cirurgia endoscópica de cinco pacientes com rinossinusite maxilar. A linha M cruzou o OSM em 112 cavidades nasais dissecadas (98%) e 140 lados na tomografia computadorizada (96%). Foi possível identificar o OSM através da linha M de todos os pacientes operados, sem complicações intra e pós-operatórias. A linha M é um marcador anatômico que aponta a localização do OSM. Assim poderá permitir uma cirurgia endoscópica nasal mais efetiva, segura e minimamente invasiva.Seios ParanasaisSeio MaxilarSinusite MaxilarCirurgia Endoscópica por Orifício NaturalLinha M: marcador anatômico para o óstio do seio maxilarLine M: anatomical marker for the maxillary sinus ostiuminfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisporreponame:Repositório Institucional da Universidade Federal do Ceará (UFC)instname:Universidade Federal do Ceará (UFC)instacron:UFCinfo:eu-repo/semantics/openAccessORIGINAL2020_tese_jgsleite.pdf2020_tese_jgsleite.pdfapplication/pdf36971583http://repositorio.ufc.br/bitstream/riufc/54850/1/2020_tese_jgsleite.pdf79e6a6725b800800163d5b7e31c8214aMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748http://repositorio.ufc.br/bitstream/riufc/54850/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52riufc/548502020-10-28 09:11:51.605oai:repositorio.ufc.br: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Repositório InstitucionalPUBhttp://www.repositorio.ufc.br/ri-oai/requestbu@ufc.br || repositorio@ufc.bropendoar:2020-10-28T12:11:51Repositório Institucional da Universidade Federal do Ceará (UFC) - Universidade Federal do Ceará (UFC)false
