RESUMEN

OBJECTIVE: Verify the effectiveness of surgical repositioning of the premaxilla and its stabilization methods in patients with bilateral cleft lip and palate during mixed dentition. DESIGN: Systematic review. MATERIAL AND METHODS: The search was conducted in 7 databases (eg, Medline via PubMed; Scopus; Central Cochrane; LILACS; Embase, Web of Science; and Sigle via OpenGrey until August 2021), using the descriptors "premaxilla", "cleft Palate", and "bone transplantation". INCLUSION CRITERIA: Clinical trials and observational studies that have patients with bilateral cleft who had a need for superior/posterior repositioning of the premaxilla on mixed dentition; Studies in any language was evaluted whitout time restriction of publication. RESULTS: From 5572 records, 6 studies were included in the review with a total sample of 212 patients. Regarding the type of stabilization used in the premaxilla, the hybrid method (rigid and complementary semi-rigid stabilization) predominated, being observed in 184 patients (86.8%). A total of 17 failures were identified related to the surgical repositioning of the premaxilla, corresponding to 8% of the total number of surgeries. A meta-analysis of prevalence was performed, only with the retrospective studies. It was observed that the effectiveness rate of premaxilla repositioning was 92%, with a CI between 0.04 and 0.13, with all included studies showing a similar failure rate (0.08-0.09). The included studies also showed great homogeneity in this analysis (I2 = 0%; P = .75). CONCLUSION: Although there are several alternatives and techniques for repositioning and stabilizing the premaxilla, the statistical result did not differ between the different techniques.

RESUMEN

Masseter hypertrophy is an uncommon condition, characterized by an increase in the volume of the masseter region, with the patient presenting functional and aesthetic complaints. Several therapeutic modalities have been suggested for this condition, however, a surgical approach usually presents consistent results in more complex cases. The objective of this article is to report a clinical case of masseter hypertrophy associated with class IV of Kin, treated through partial removal of the masseter muscle, bichectomy and genioplasty. Surgery was performed under general anesthesia in a hospital setting. The planning was previously carried out through prototyped models and radiographs to remove the excess bone shown in the mandibular angle region. Surgical treatment of masseter hypertrophy is effective and long-lasting in severe cases. Additional surgical procedures must be performed in order to provide the best possible result according to the facial deformity found.

RESUMEN

Hemangiomas are benign vascular lesions characterized by endothelial vascular proliferation and may demonstrate aggressive clinical features. Intraosseous hemangiomas are uncommon and the maxillary location rare, with few cases described in the literature. The treatment of these lesions varies, however they have a better prognosis when a surgical treatment through resection is performed. The aim of this study is to report a case of right maxillary cavernous intraosseous hemangioma treated by surgical resection with previous embolization. The diagnosis was made through incisional biopsy and immunohistochemical examination. An aggressive lesion profile was observed through the Ki67 marker. During surgery, a temporary ipsilateral external carotid artery ligation was performed to minimize possible bleeding. Weber-Fergson surgical access was performed and total surgical resection through hemi-maxillectomy. The patient is stable after 30 months of follow-up without relapses. In suspected cases of intraosseous hemangiomas, accurate diagnosis and total surgical resection of the lesion is essential. The use of therapeutic mammoths that minimize sagging during and after the procedure such as embolization and arteriography should always be performed.

RESUMEN

Objetivo: A proposição do presente trabalho foi analisar a frequência relativa dos vários tipos histológicos de cistos e tumores odontogênicos benignos. Metodologia: por meio do estudo retrospectivo de prontuários dos pacientes submetidos a tratamento no Hospital Santo Antônio - obras Sociais Irmã Dulce, Salvador-BA, Brasil, sob anestesia geral, durante o período de 2004-2010. Foram avaliados: idade, gênero, tipo histológico, sítio anatômico, tratamento realizado e recorrência. Resultados: observaram-se 34 pacientes do gênero feminino e 24 do gênero masculino. o ameloblastoma (43%) foi o tipo histológico mais frequente, seguido do tumor odontogênico ceratocístico (26%), mixoma odontogênico (10%) e odontoma (9%). entre os cistos, o maior percentual foi de cisto paradentário (60%). A média de idade foi de 28,1 anos. A principal localização anatômica foi a mandíbula em região posterior.


Purpose: The purpose of this study was to analyze the relative frequency of the various histologic types of odontogenic cysts and tumors. Methodology: A retrospective study was conducted based on the medical records of patients undergoing treatment at Hospital Santo Antônio - obras Sociais Irmã Dulce, Salvador-BA, Brazil, under general anesthesia during the period 2004-2010. Age, gender, histological type, anatomic site, treatment performed and recurrence were evaluated. Results: The study comprised 58 patients (34 females and 24 males). Ameloblastoma (43%) was the most common histological type, followed by the keratocystic odontogenic tumor (26%), odontogenic myxoma (10%) and odontoma (9%). Among the cysts, the paradental cyst showed the highest percentage (60%). The mean age was 28.1 years. The main anatomical location was the posterior region of the mandible.
