RESUMO
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 78months with a mean of 42.9months. 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<0.05), and paresthesia was observed exclusively in cases of mandibular canal fenestration (P<0.01). CONCLUSIONS: Complementary treatment with Carnoy's solution and peripheral ostectomy appear to provide efficient treatment for KOTs. Complications originating from the use of the solution are less frequent and less serious than complications associated with cryotherapy. Neuropathy seems to be related to direct contact between the solution and the epineurium.

The case of a 40-year-old male patient with obstructive sleep apnea syndrome (OSAS) is reported, with emphasis on treatment with a dental appliance. This therapeutic approach, which has been focused on recent research, has as its objective, the posturing of the mandibule and, consequently, the tongue more anteriorly, thus in turn leading to an increase in the posterior oropharyngeal airway space (PAS). Cephalometry contributed determining in this case whereby enlargement limits were observed in the PAS with mandibular displacement. Clinical and polysomnographic controls showed subjective reduction of the excessive daytime sleepiness and objective decrease in apneas intensity to normal limits. Eight months follow-up evidenced the steady improvement.
