ABSTRACT
Resumen: Introducción: El síndrome de Lesch-Nyhan (SLN) es un trastorno hereditario recesivo relacionado con el cromosoma X, causado por la deficiencia de la enzima hipoxantina-guanina fosforribosil transferasa (HPRT). La automutilación compulsiva y distonía ocurre antes del año de edad y se expresa con mordeduras persistentes en la mucosa oral, labios, lengua, dedos y hombros. La intervención odontológica realizada en la mayoría de estos pacientes es la extracción dental múltiple para prevenir lesiones graves secundarias. Objetivo: presentar un caso clínico de SLN y describir el manejo odonto-pediátrico en pacientes con conducta automutilatoria. Caso clínico: Paciente varón, 7 años de edad, portador de SLN. Fue referido a la Unidad de Odontología desde el Departamento de Neurología Pediátrica para la evaluación y manejo de heridas autoinfligidas en dedos, labios y mejillas asociadas a una pérdida de peso y disminución de la ingesta de alimentos. El procedimiento quirúrgico consistió en extracciones dentales múltiples, y remodelación quirúrgica de las crestas alveolares residuales, bajo anestesia general. Al segundo mes posquirúrgico el paciente fue dado de alta definitivamente, con un adecuado estado nutricional y sin signos de automutilación en manos ni en cavidad oral. Conclusio nes: A pesar, que el SLN es infrecuente, es esencial saber cómo proceder para dar la mejor calidad de vida a los pacientes y sus familias. Las extracciones tempranas del diente, como fase inicial en casos severos, parecen ser la alternativa más útil para minimizar el daño y el dolor por la automutilación.
Abstract: Introduction: Lesch-Nyhan syndrome (LNS) is an inherited recessive X-related disorder caused by the deficiency of the enzyme hypoxanthin-guanine phosphorribosyl transferase (HPRT). Compul sive self-mutilation and dystonia occurs before the first year of age and is expressed by persistent bites on the oral mucosa, lips, tongue, fingers, and shoulders. The dental intervention performed on most of these patients is multiple tooth extraction to prevent serious secondary lesions. Objective: To present a clinical case of LNS and describe pediatric dentistry management in patients with self-mutilating behavior. Clinical case: Male patient, 7 years old, LNS carrier. He was referred to the Dental Unit from the Department of Pediatric Neurology for evaluation and management of self-inflicted wounds on fingers, lips and cheeks associated with weight loss and decreased food intake. The surgical procedure consisted of multiple extractions, surgical remodeling of the residual alveolar ridges under general anesthesia. In the second postoperative month, the patient was discharged definitively, with an adequate nutritional status and no signs of self-mutilation in hands or oral cavity. Conclusions: Although LNS is rare, it is essential to know how to proceed in order to provide the best quality of life for patients and their families. Early tooth extractions, as an initial phase in severe cases, seem to be the most useful alternative to minimize damage.

A reconstrução labial representa um desafio ao cirurgião plástico. Os lábios são o centro dinâmico do terço inferior da face, sendo fundamentais para mímica e expressão facial, fala, deglutição, sucção e contenção de secreções salivares, sem esquecer-se do componente estético. Portanto, a reconstrução labial deve ter como objetivo o restabelecimento funcional da estrutura lesada e um bom resultado estético. Este artigo relata um caso de lesão labial traumática grave e sua reconstrução, com a utilização do retalho de Karapandzic. Os autores demonstram sua funcionalidade e fácil execução, assim como seu resultado final.
Lip reconstruction is a challenge to the plastic surgeon. The lips are the dynamic center of the lower third of the face, being essential for facial movements and expression, speech, deglutition, suction, and containment of salivary secretions, as well as esthetic appearance. Therefore, the objective of lip reconstruction should be functional recovery of the damaged structure and a good esthetic result. This article reports a case of severe traumatic labial injury and reconstruction, using the Karapandzic flap. The authors demonstrate its functionality and easy implementation as well as the final result.

Introdução: A cirurgia reconstrutiva do lábio, seja superior ou inferior, possibilita sua reconstrução por meio de uma variedade de técnicas cirúrgicas. Nessas reconstruções, é importante avaliar as características do tecido (cor da pele, textura), o qual sempre que possível deve ser utilizado próximo ao local da lesão, para fornecer o melhor resultado estético e funcional possível. Relato do Caso: O presente trabalho tem como objetivo descrever a técnica de Bernard-Burow para reconstrução de lábio inferior, e revisar a anatomia do terço inferior da face, por meio do relato de caso de um paciente que foi mordido por um cavalo e teve avulsão de lábio inferior e porção mentoneana e submentoneana da face.
Background: The reconstructive surgery of the lip, upper or lower, presents a variety of techniques and procedures. In reconstructive surgery of lip is important to evaluate the characteristics of tissue (skin color, texture), which wherever possible should be used near the site of injury to provide the least morbidity and best tissues in colors and texture. Case Report: This article aims to describe the Bernard-Burow technique for reconstruction of lower lip, and review the anatomy of the lower third of the face, through the case report of a patient who was bitten by a horse and had avulsion of lower lip and mentoniane portion of the face.

Queimaduras elétricas em lábios são raras (5,6% 7% dos casos de queimadura elétrica),mesmo em crianças, sendo o sexo masculino duas vezes mais atingido. Por serem incomuns,são de difícil e contraditório manejo no atendimento inicial e no tratamento das sequelas.No presente trabalho é descrito um caso de queimadura elétrica em lábio em uma pacientede 2 anos. Foi submetida a tratamento cirúrgico 10 dias após a queimadura e apresentouresultado estético e funcional satisfatório após 8 meses de evolução.
Electric burn injuries in lips are rare (5.6% 7% are the range of occurrences), even inchildren, never the less statistics shows that male patients are two times more likely to sufferthis burns. Due to the fact, that this cases are uncommon they often have difficult andcontradictory first aid protocols, as well as in the following treatment. This text reports atwo-year-old-female patient who had a lip burn injury. The patient had suffered a surgicalproceeding 10 days after the burn took place and also had presented a satisfactory functionalevolution, 8 months later.
