Giant sialolith of submandibular gland: case report

The sialolith, also known as saliva stone or sialolithiasis is a calcified structure which develops inside the salivary ductal system or on the salivary gland parenchyma; it grows gradual, asymptomatic, and slowly. Most of the stones are sized less than 10 mm and only 7% of them are larger than 15 millimeters; those are considered giant salivary gland stones. Objective: This study aimed to report a case of two sialoliths that have merged, forming a giant sialolith, located in the Wharton duct in the left submandibular gland. Methods and Results: Clinical diagnosis was confirmed by occlusal and panoramic radiographs. A surgical removal was performed with intraoral incision under local anesthesia, through sialolith anchorage by suture thread and removal of two sialoliths, sized about 13 mm and 16 mm. Marsupialization suture was performed at the local where the incision was made, forming a new gland duct. Conclusion: The sialolithiasis treatment methods are very different and should be taken into account the affected gland, size and location of sialolith, always opting for the more conservative methods

LEVANTAMENTO DE SEIO MAXILAR COM UTILIZAÇÃO DE ENXERTO HOMÓGENO

A implantodontia moderna tem buscado cada vez mais novas tcnicas para resolver situaes adversas com relao s reas de ausncia de tecido sseo, causadas por perdas dentais precoces. Este artigo consiste na apresentao de um relato de caso clnico, no qual foi utilizado o enxerto homgeno obtido do Banco de Tecidos Msculo Esqueltico do HC-UFPR. Essa modalidade teraputica mostrou-se satisfatria por apresentar menor tempo clnico operatrio, menor desconforto ao paciente e quantidade ssea necessria independente da extenso da rea receptora

Tratamento cirúrgico das fraturas zigomáticas, utilizando-se de miniplacas e parafusos do sistema de 1,5mm: estudo clínico-radiográfico em humanos

As fraturas do complexo zigomaticomaxilar figuram dentre os traumatismos mais incidentes no arcabouço facial. Baseado na complexidade e grande variedade de diagnóstico e tratamentos relatados, foi proposta desse trabalho avaliar, clinica e radiograficamente, fraturas zigomáticas unilaterais, tratadas através de fixação interna rígida, com miniplacas e parafusos de 1,5mm. Foram analisados 15 pacientes com fraturas unilaterais do complexo zigomaticomaxilar, comparados a 15 pacientes sem fraturas, para que fosse realizada análise comparativa da área e perímetro das cavidades orbitárias, bem como da distância do dorso nasal à proeminência zigomática entre ambos os grupos. Quando comparados os dados dos pacientes portadores de fraturas e os sadios, observou-se que as diferenças não foram estatisticamente significantes.The fractures of the zygomaticmaxillary complex represents among the most incident traumatisms in the facial outline. Based on the complexity and great diagnosis variety and reported treatments, the purpose of this study was to evaluating clinical-radiographic zygomatic unilateral fractures, treated through internal rigid fixation with 1.5mm miniplates and screws. Fifteen patients with unilateral zygomaticmaxillary complex fractures were compared to fifteen patients without fractures, so that it was accomplished comparative analysis of the area and perimeter of the orbital cavities, as well as of the distance of the nasal back to the zygomatic prominence between both the groups. When compared the treated patients' data and the healthy ones, it was observed that the differences were not statistically significant

Clinical and radiographic evaluation of surgical treatment of zygomatic fractures using 1.5 mm miniplates system

Fractures of the zygomaticomaxillary complex are among the most common face traumas. Based upon the complexity and great variety of reported diagnoses and treatments, the proposal of this study was to evaluate, clinically and radiographically, unilateral zygomatic fractures treated through internal rigid fixation with miniplates and screws of 1.5 mm. Material and Method: 15 patients with unilateral fractures of the zygomaticomaxillary complex were analyzed, and compared with 15 patients without fractures so that a comparative analysis of the area and the perimeter of the orbital cavities could be made, as well as the distance from the nasal point to the zygomatic prominence between both groups. Results: In the radiographic analysis, the both groups presented similarity in the perimeter and in the area of the orbital cavities. Concerning the distance from the nasal point to the zygomatic prominence, only the operated group showed a significant difference between the sides, even though clinically the observation of the asymmetry had been absent or discreet. Conclusions: The treatment of unilateral fractures of the zygomaticomaxillary complex with the use of plates and screws of the 1.5 mm system proved to be effective, showing good esthetic results and low complication rates
