Vagal Paragangliomas: From Reducing Morbidity to Improving Quality of Life

Abstract

Vagal paragangliomas are rare tumors. Advances in the imaging have aided the diagnosis and assessment of this disease. Surgery is the mainstay of the treatment however radiotherapy has been tried in the selected cases. Surgery is associated with some mortality but with a lot of morbidity in view of cranial nerve deficit. The necessity to prevent additional cranial nerve deficits needs thorough preoperative evaluation and influences the therapeutic approach. This study involves the retrograde evaluation of five patients of vagal paraganglioma histopathologically confirmed, all the patients were operated via trancervical approach. Preoperatively three of five had 9, 11 and 12th cranial nerve involvement, one had horner's syndrome. Postoperative vocal rehabilitation was done in all the patient by medialisation thyroplasty Issiki type 1. Though vagal paragangliomas are associated with mortality and morbidity. Surgical treatment should aim at reducing mortality. Vagal nerve morbidity can be taken care as a planned and staged procedure mainly involving restoring voice as rest of concerns are taken care by compensation from opposite nerves.
