Irregular soft tissue bony erosion and lucencies remain in both sides of the mandible. Alveolar bone margin erosions. Bone expansion at the posterior alveolar margin is now associated with a small gaseous cavity, in keeping with active infection. There is cortical breach of anterior left parasymphyseal mandible surface, measuring about 5 mm. Small 2 mm inferior left bone sinus communicates with the submental region. More lateral anterior left mandibular erosion enlarging from 10 mm to 12.5mm. A 7 mm inferior right parasymphyseal mandible sinus communicates with right submental region. Both mandibular canals are involved in the low density sequestrum. Previous left glossectomy. No nodal disease.
CONCLUSION:Ongoing destruction of the mandible. New bone sinuses are seen extending inferiorly and anteriorly on the left. Enlarging right inferior mandibular sinus. Ongoing bone expansion at posterior right alveolar margin now associated with a small air cavity.
