Treatment of oral myiasis in a patient with implant-supported fixed prosthesis.

Oral myiasis is a rare parasitic disease that requires immediate treatment once diagnosed. However, no standard treatment protocol can be found in the literature. Through a clinical-surgical report, we present the case of an 82-year-old man with lesions extending through the vestibule and alveolar ridge of the maxilla on both sides, in addition to occupying a large part of the palate, with a considerable number of larvae. The patient was initially treated with a single dose of systemic ivermectin (6 mg orally) and topical application of a tampon soaked in ether. The larvae were then surgically removed and debridement of the wound was performed. A crushed tablet of ivermectin 6 mg was applied topically for 2 days, the remaining larvae were again mechanically removed, and the patient received intravenous antimicrobial therapy. Treatment with systemic and topical ivermectin combined with antibiotic therapy and debridement proved to be effective in treating oral myiasis.

Guided neural regeneration with autologous fat grafting and oxygen hyperbaric therapy.

The loss of continuity of the nerve structure interrupts the transmission of nerve impulses and leads to the disorganization of functional activities. Many methods, as the use of neurogenic factors, aid in the process of neural regeneration by accelerating or improving peripheral nerves neoformation. The adipose tissue is abundant in the human body, and it has presented promising results in the regeneration of peripheral nerves. We carried out a randomized controlled study in 9 months, using 45 male Wistar rats, 80 days old, and the sciatic nerve was chosen for analysis. The control animals were divided into three groups - Initial group (IG), Final group (FG), and denervated group (DG) - with seven animals each. The experimental groups, with twelve animals each, were polyethylene tube filled with fat (EGF) and polyethylene tube without filling (EGwf). All groups, except IG, were submitted to 10 sessions of hyperbaric oxygen treatment of 1h 45 min in alternating days. Functional evaluation by walking-track was assessed using the Catwalk XT® software and tissues were harvested and stained with 1% toluidine blue for histological analysis. Quantitative data were first analyzed with the Kolmogorov Smirnov normality test. Comparison between the four groups was analyzed by ANOVA followed by Tukey Test. We concluded that hyperbaric oxygen therapy had positive results on morphometric and functional parameters. However, no significant differences were found regarding the use of autologous fat graft.

Treatment of Fracture Sequel in the Mandibular Angle Region.

Because of the anterior disposition on the face and the fragility of the anatomy, the mandible is commonly affected in facial fractures, and the angle region represents 32% of the mandibular fractures; therefore, the objective of the paper was to present a proposal for late correction of the mandibular fracture already consolidated and with occlusal alteration. Patient J.C.P.R., 32, during anamnesis reported loss of sensibility in the mentalis region as well as unilateral posterior open bite for having been a victim of an automobile accident about 1 year and 3 months ago. Physical examination showed elevation in the right mandibular angle region due to the poor positioning of fractured stumps. It has been found that the patient suffered a simple fracture at the mandibular angle, but that had not been treated previously, and it was necessary to treat the fracture sequel. Refraction was performed with a new reduction and fixation through titanium plates and screws, showing that, even being late, the procedure to reduce the fracture sequela was effective, even with the correct functional occlusal adjustment.
