title: Isolated head drop triggered by neck surgery following concomitant chemoradiotherapy.
abstract: Dropped head syndrome (DHS) is characterized by severe weakness of neck extension that occurs in isolation or association with a generalized neuromuscular disorder. Multietiologies may be responsible for DHS, including radiotherapy, which may cause a delayed form of DHS. However, DHS acutely triggered by neck surgery after chemoradiotherapy is rare. The author reports a case of acute onset of isolated DHS following selective neck dissection surgery after concomitant chemoradiotherapy for laryngeal cancer.
