This entity mostly affects the head and neck region, including the lips, tongue, buccal mucosa, gingiva, or palate. VM may cause functional and aesthetic impairments. The anatomical structure and shape of the lips provide an important aesthetic accent for an individual. Therefore, management of VM in the lip area without postoperative defects or scarring is challenging. In this brief communication article, we present a conservative approach to lip VM in a nine-year-old boy using a bleomycin injection that had good aesthetic and functional outcomes. Injection of 2 mL of 1/10 of 15 mg bleomycin in a saline dilution into the lip mucosa may present a drug reaction as a white plaque and reddish owl eye lesion that takes up to three weeks to resolve without a scar. It is important to recognize the characteristics and self-limiting nature of postoperative bleomycin complications to avoid unnecessary treatment.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10618664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71428991","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}

They can result in various complications, including injury to the surrounding nerves. Owing to its anatomy, trauma to the maxillary antrum can result in injury to the middle superior alveolar nerve (MSAN) and the anterior superior alveolar nerve (ASAN). The purpose of this study is to evaluate neurosensory deficits (NSD) present in maxillary gingiva, incisors, and premolars after injury to the anterior wall of the maxillary antrum.</p><p><strong>Materials and methods: </strong>This prospective study was conducted among 39 patients sustaining unilateral fractures of the anterior maxillary sinus wall. Clinical neurosensory tests including two-point discrimination and fine touch discrimination were performed to classify the extent of nerve injuries as mild, moderate, severe, or anesthetic. Additional temperature discrimination and pulpal sensibility tests (electric pulp testing and cold testing) were carried out. A comparison of radiographic fracture patterns and severity of nerve injury was done. Testing was carried out immediately after trauma and at 2-month follow-up.</p><p><strong>Results: </strong>More than half of the patients assessed in the study group presented with NSD of the teeth and gingiva after trauma. The incidence of deficits varied with the type of test used to measure them. Most frequently, patients presented with both loss of two point as well as fine touch discrimination thresholds. Severe nerve injuries were associated with loss of temperature discrimination clinically and displaced fractures radiographically. There was no significant relationship between the recovery of pulpal and gingival sensation. The patterns of injury and recovery in ASAN and MSAN were similar.</p><p><strong>Conclusion: </strong>NSD after trauma to the maxillary antrum is relatively common. Clinical loss of temperature discrimination and radiographic signs of fracture lines passing through the canalis sinuosus are predictors of persistent and severe oral NSD.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10618660/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71428992","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}
