The Suh Muscle Hook: A New Muscle Hook for Tight Extraocular Muscles during Strabismus Surgery

Abstract

Purpose: To introduce an advanced muscle hook to decrease risks and create more feasible extraocular muscle surgeries for physicians. Case Report: Tight extraocular muscles during strabismus surgery could be extremely challenging even in experienced hands due to restricted globe rotation, limited view, and lack of muscle elasticity. Although a variety of surgical instruments have been introduced through the years, traditional muscle hooks such as the Jameson hook are largely unchanged and are bulky and cumbersome. Using the traditional muscle hook under situations such as pediatric strabismus surgery with smaller eyes and extraocular muscles may increase the risk of perforating the globe or even rupturing the muscles. We developed the "Suh muscle hook", which has a 0.55 mm wide grooved track in a 1.1 mm wide horizontal bar, a semi-sharp dissecting tip, and a 30-degree bending near the handle accommodating for nasal bridge to better facilitate surgeons dealing with tight extraocular muscles and minimize risks during strabismus surgery.

Novo gancho muscular milimetrado para cirurgia de estrabismo

“…Embora uma variedade de instrumentos cirúrgicos tenha sido introduzida ao longo dos anos, os ganchos musculares tradicionais, como o gancho de Jameson, permanecem imprescindíveis. (7) Para cada caso, podem ser necessárias variações de manuseio e o posicionamento desses ganchos, podendo ter interferência na segurança do procedimento e até mesmo no resultado, uma vez que as marcações musculares são da ordem de milímetros. (1,3,8) Em muitos serviços, há grande rotatividade na equipe auxiliar, e isso pode ocasionar um aumento na dificuldade e no tempo da cirurgia.…”
