The carotid artery was blocked in three patients. In one of these the artery was reconstructed with a vascular prosthesis, while two underwent carotid ligation. Eight patients suffered from a cranial nerve dysfunction (defect) and two suffered postoperatively from a hoarse voice, four had a glossal deviation, five had Horner's syndrome and one had a deviation of the lip angle. One patient had a congestive cough. The histopathological diagnosis in all nine cases was MCBT. One patient had metastases to a cervical lymph node and lung and another had liver metastasis. The median follow-up period was 3 years (range 6 months to 14 years). Six patients survived surgery, of whom two underwent radiotherapy. Two patients died and one could not be traced.
All five PMMFs and seven ADM tissue patches survived. No pharyngeal fistula occurred. Satisfactory healing was observed between the wound margin and ADM 10 days after operation. The trauma area was completely covered by growing epithelium 18–37 days after operation. To some degree, stenosis of the pharyngeal cavity did occur, but patients could have a regular diet following dilatation of the stenosis. Five patients are free of disease after 18–42 months of follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
