Objective: To evaluate the application of a limited transverse incision technique to treat the carpal tunnel syndrome, with concern to its safety and efficacy in the opening of the flexor retinaculum (FR). Method: A prospective analysis of thirty FR release procedures performed on twenty-eight patients subjected to the proposed incision technique. Safety and total opening of the FR were evaluated through a questionnaire and an endoscopic inspection respectively. results: No major complications were observed. Two cases presented small local hematoma. One patient presented with transient neuropraxia of digital branch. In two of the first five cases, incomplete FR opening was identified during endoscopic revision with need of complementary opening. All patients reported relief of paresthesias and nocturnal pain symptoms. conclusion: The technique was safely performed on the prospection group, no major complications were detected and the opening of FR was observed in the majority of the patients. Key words: carpal tunnel syndrome, surgical procedures, minimally invasive, safety.Utilização de técnica de incisão transversal mínima no tratamento da síndrome do túnel do carpo resUMO Objetivo: Avaliação de técnica de incisão limitada no tratamento da síndrome do túnel do carpo, quanto à segurança clínica e efetividade na abertura do Retináculo Flexor (RF). Método: Estudo prospectivo de trinta procedimentos realizados em vinte e oito pacientes submetidos a técnica com incisão transversa mínima. A segurança da técnica e a abertura total do RF foram avaliadas através de questionário baseado em observações clinicas e inspeção endoscópica, respectivamente. resultados: Não foram observadas complicações maiores. Um único paciente apresentou neuropraxia de nervo interdigital. Dois pacientes apresentaram hematoma local pequeno. Em dois dos cinco primeiros casos observou-se uma abertura incompleta do RF, sendo necessária abertura complementar. Todos os pacientes apresentaram melhora do quadro clínico de dor noturna e parestesias. conclusão: A técnica foi executada com segurança no grupo analisado, sem a ocorrência de complicações graves, e com abertura do RF na quase totalidade dos casos. Palavras-chave: síndrome do túnel do carpo, cirurgia, minimamente invasiva, segurança.
