CONCLUSIONS
CBS is an uncommon yet detrimental complication encountered in head and
neck cancer patients, especially with a history of radiotherapy and
radical neck dissection. It is an emergency which necessitates the use
of angiography for diagnosis, and in most cases for treatment. However,
surgical ligation could still be a treatment option. Since, it has a
high mortality and neurologic morbidity, preventing CBS would be the
most effective treatment method, especially in patients with soft tissue
exposure, necrosis and fistula because the countdown is approximately
set to 4 months.
