tongue removal with 2 muscle flape , stiffness of neck.

Has anyone experiencing what my hub is ?,he had 3 surgeries and 30 hyperbaric oxygen treatments ( HBO), he has had to have 2 muscle or tongue flaps as some call them , his neck will not bend side to side or front to back , he also when he bends over it looks like the little flap blocks his airway and he cannot breathe. He said he would stoop , no more surgery for him .! JO
