Intraoral examination showed gingival bleeding and an ecchymotic area extending from the canine to the retromolar area (Figure 1).

CT confirmed the multiloculated appearance, bone expansion, and preservation of the dental structures within the affected area (from the canine to the left mandibular angle, involving the entire horizontal branch of the mandible) (Figure 2).
Preoperative angiography: left common carotid angiogram, lateral projection, and arterial phase showing extensive mandibular AVM with arterial supply from multiple sources and drainage into the dilated inferior alveolar vein.

This time in combination with an intraoral approach, transcortical puncture was used to access the interior of the mandible with a trocar under radioscopic control and angiographic support (Figure 4).

There are no aesthetic sequelae, and her permanent mandibular left second molar has erupted correctly; although radiographically they show some root resorption they have no significant mobility (Figures 5 -7).
