Oral Dokuları Etkileyen Arteriovenöz Vasküler Malformasyon Vakalarında Dental Tedavi Yaklaşımı

Abstract

Large arteriovenous vascular malformations (AVM) of the jaws are relatively rare and potentially life-threatening lesions. When these lesions are not suspected, extraction of teeth or other surgery procedures can be fatal in dentistry. Gingival bleeding seems to be a symptom common to most documented cases. Despite their benign histology, deep lesions can produce serious systemic signs and symptoms due to extensive arteriovenous shunting and soft tissue hypertrophy. Mandibular AVM shows a wide variety of signs and symptoms, such as dental mobility, otalgia, secondary pain due to thrombosis, facial asymmetry, and cosmetic distress. A clinical case report was presented in this study. A 24-year-old girl, seen for gingival bleeding during oral hygiene and facial asymmetry, was found to have a high-flow AVM located around the right mandible. In dental and clinical examination, although she had good oral hygiene, common gingival bleeding was observed. At the mandibular rigth molar region, non-hemorrhagic, gingival granulomatous swelling was noted. Scaling and root planning and polishing was performed to the teeth carefully. The patient was called maintenance phases. During 2 year, no recurrence of the lesion has been seen. Dentists must always consider the possibility and be able to recognize the clinical signs of AVMs in order to propose proper treatment. Because, AVMs of the maxillofacial region give rise to dental emergencies and may cause disfigurement, morbidity, even death.
