Laryngotracheal separation surgery in a patient with severe Angelman
syndrome involving a 19.3 Mb deletion on 15q11.2--q14
Abstract
Previous reports of clinical course of Angelman syndrome (AS) described
typical histories of choking, dysphagia, and severe pneumonia, but there
were few bedridden cases or none requiring laryngotracheal separation
surgery (LTS) were existed. We report a severe bedridden case of AS
requiring LTS involving a 19.3 Mb deletion on 15q11.2–q14.
