Among the bleeding group, there were no associations between postoperative bleeding and systemic diseases, antithrombotic medications, or dental treatments. In 36.2% of cases, compression hemostasis alone was sufficient to resolve the bleeding. In the inflammation group, 29% of the cases required extraoral incision and drainage as emergency treatment, while 53% of the cases required subsequent hospitalization. Factors associated with hospitalization included underlying diseases (especially diabetes mellitus), procedures on mandibular teeth (especially third molars), and age older than 30 years.</p><p><strong>Conclusion: </strong>Ensuring adequate hemostasis after dental procedures is essential regardless of the patient's underlying medical conditions. Dentists must also educate patients on pressure hemostasis techniques. Patients with underlying medical conditions, such as diabetes, have a higher possibility of requiring hospitalization if inflammation occurs. Therefore, preventive measures against inflammation should be implemented in these patients.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"50 6","pages":"326-332"},"PeriodicalIF":0.9,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FFF supports dental implantation and prosthetic rehabilitation, with its vascularized periosteum enhancing osteogenic potential. Despite these advantages, unexpected ossification of the flap's vascular pedicle may occur, potentially mimicking tumor recurrence and causing diagnostic uncertainty. This case report describes a 38-year-old male with left buccal squamous cell carcinoma treated by wide excision, modified radical neck dissection, and reconstruction using a radial forearm free flap. Postoperative radiotherapy led to complications including trismus and alveolar bone exposure, culminating in a pathological mandibular fracture. Mandibular reconstruction was performed using an FFF. Over 4 years of follow-up, computed tomography revealed ossification within the vascular pedicle. Notably, the patient remained asymptomatic, maintaining normal speech and swallowing without functional impairment. Pedicle ossification may present radiographically as a suspicious bony change misinterpreted as tumor recurrence. Routine follow-up imaging such as computed tomography is essential for differentiation. Although trismus, bony swelling, or pain may occur, surgical intervention is typically deferred unless symptoms develop.
