Oral submucous fibrosis (OSMF) is a chronic inflammatory fibrotic disorder with malignant potential. The angiogenetic pathways in OSMF remain obscure due to limited research, necessitating an in-depth review. This review aimed to illuminate the cryptic pathogenetic mechanisms of angiogenesis in the disease progression/fibrosis of OSMF and its malignant transformation, providing insights for improved treatment. Extensive literature searches were conducted across an array of databases until October 2023. Original research articles on angiogenesis in OSMF were included, and the risk of bias was assessed using the modified Newcastle-Ottawa scale. RevMan ver. 5.4 (Cochrane Collaboration) was used for data analysis. Thirty-four articles were included for qualitative synthesis and seven for quantitative analysis. Findings revealed that angiogenesis was significantly increased in early-stage OSMF but decreased as the disease advanced. It was also associated with the severity of epithelial dysplasia and malignant transformation. A random-effects model confirmed the upregulation of angiogenesis as a significant risk factor in early-stage fibrosis and malignant transformation. The mounting evidence reinforces that angiogenesis plays a crucial role in the progression of early-stage fibrosis of OSMF and its malignant transformation, opening avenues for diagnostic and therapeutic interventions.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11535123/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142559393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 34-year-old male patient underwent orthognathic surgery due to facial asymmetry. When emerging from general anesthesia, blood pressure elevated suddenly, and severe agitation occurred. After extubation, desaturation occurred immediately, resulting in cyanosis and loss of consciousness. An emergency cricothyroidotomy was performed, and oral intubation was required to maintain the airway. The patient was sent to the intensive care unit on a ventilator. On postoperative day 2, the red blood cell count and hemoglobin level decreased significantly. Electrocardiogram showed abnormalities, although vital signs were stable and no bleeding was observed. Laryngospasm often occurs under general anesthesia, resulting in sustained closure of the vocal cords and obstruction of the airway. This condition can be life-threatening, and awareness of the various precipitating factors is important. Orthognathic surgery is a risk factor for laryngospasm because its surgical site affects the airway, and it involves discharge of blood via intraoral wounds.
