Keratocystic odontogenic tumors and Carnoy's solution: results and complications assessment

Oral Diseases (2012) 18, 548–557 Objective: Keratocystic odontogenic tumors (KOTs) can be treated with Carnoy’s solution, although this treatment modality is not free from complications. It is important to verify the incidence of complications after the use of Carnoy’s solution and compare these with the literature. Materials and methods: This study verified the effects of a complementary treatment for KOTs and assessed the incidence of such complications as recurrence, infection, sequestrum formation, mandibular fracture, dehiscence, and neuropathy. Results: Twenty‐two KOTs treated with Carnoy’s solution combined with peripheral ostectomy were included, and the follow‐up period varied from 12 to 78 months with a mean of 42.9 months. Complications included recurrence (4.5%), dehiscence (22.7%), infection (4.5%), and paresthesia (18.2%). No difference was found among lesions associated (9.1%) or not (0%) with nevoid basal cell carcinoma syndrome (P > 0.05). Dehiscence was influenced by marsupialization (P
