Post-traumatic-Zygomaticocoronoid Ankylosis: A Rare Clinical Case Report.

Fusion of the zygomatic bone to the coronoid process of the mandible is a rare phenomenon reported in the literature and commonly called as zygomaticocoronoid ankylosis. It can be sequel of trauma or infection in the midfacial region, mimicking a wide range of problems including the common temporomandibular joint ankylosis and dysfunction. Maxillofacial trauma involving the displaced fracture of zygoma can obstruct the movement of coronoid and if not treated can cause ankylosis between both bones. It is very diffi cult to identify zygomaticocoronoid ankylosis on conventional radiographs and requires the through clinical and advanced radiological evaluation like cone-beam computed tomographic (CBCT) to diagnose it. CBCT can be a great help to identify the size and extension of ankylotic mass and decide the approach to remove it. Zygomaticocoronoid ankylosis can be approached intraorally by Keen’s incision, and extraorally through a hemicoronal approach we have approached intraorally. Here, we present surgical management of post-traumatic zygomaticocoronoid ankylosis in 42-year-old male patient who had trismus for 18 years.

Complications of exodontia: A retrospective study.

Purpose: The purpose of this study was to analyze the incidence of various complications following routine exodontia performed using fixed protocols. Materials and Methods: A total of 22,330 extractions carried out in 14,975 patients, aged between 14 and 82 years, who reported to the Department of Oral and Maxillofacial Surgery at Padmashree Dr. D. Y. Patil Dental College and Hospital, Nerul, Navi Mumbai, were evaluated for various complications. Results: The most common complications encountered were tooth fracture, trismus, fracture of cortical plates and dry socket. Wound dehiscence, postoperative pain and hemorrhage were encountered less frequently. Luxation of adjacent teeth, fracture of maxillary tuberosity, and displacement of tooth into adjacent tissue spaces were rare complications. Conclusion: The practice of exodontia inevitably results in complications from time to time. It is imperative for the clinician to recognize impending complications and manage them accordingly.

Avaliação da prevalência de trismo em pacientes submetidos à exodontia de terceiros molares / Evaluation of the prevalence of trismus in patients submitted to third molar surgery

Objetivos: Avaliar o grau de abertura bucal pós-operatória e fatores que possam influenciá-la, em pacientes submetidos à remoção de terceiros molares inferiores e superiores no ambulatório de Cirurgia e Traumatologia Bucomaxilofacial da Universidade Federal de Santa Maria, Rio Grande do Sul, Brasil. Método: Foram examinados pacientes submetidos à exodontia de terceiros molares inferiores e superiores no ambulatório de Cirurgia e Traumatologia Bucomaxilofacial da Universidade Federal de Santa Maria. A abertura bucal dos pacientes foi medida em milímetros minutos antes, dois e sete dias após a exodontia, com o uso de uma régua. Resultados: O trismo é uma ocorrência freqüente nas cirurgias de terceiros molares inclusos, ocorrendo em 56,5% dos pacientes no período de dois dias após a cirurgia, havendo uma redução na reavaliação após sete dias. Conclusão: Conclui-se que o trismo é uma ocorrência freqüente nas cirurgias de terceiros molares inclusos e que não foram encontradas relação significante entre o trauma da cirurgia e a presença de trismo.
