ABSTRACT
We reviewed the postoperative functional outcome following surgical resection of paragangliomas
in patients with and without preoperative cranial nerve dysfunction. Patients who
underwent surgical resections of head and neck paragangliomas were reviewed with functional
outcomes defined as feeding tube and/or tracheostomy dependence, need for vocal cord
medialization, and incidence of cerebral vascular accidents as primary end points.
Secondary end points included pre- and postoperative function of lower cranial nerves
and the impact of this dysfunction on long-term functional status. Sixty-one patients
were identified: 27 with carotid paraganglioma (CP), 21 with jugular paraganglioma
(JP), 8 with tympanic paragangliomas, 4 with vagal paragangliomas (VPs), and 1 with
aortopulmonary paraganglioma. Following resection, 8 patients were feeding tube dependent,
14 patients required vocal cord medialization, 2 patients suffered strokes, but no
patients required tracheostomy tubes. Twenty percent of patients (4/20) with JP and
postoperative cranial neuropathies were feeding tube dependent, and 80% of patients
(4/5) with CP and postoperative cranial nerve dysfunction were feeding tube dependent.
Cranial nerve deficits were more common in patients with JP relative to those with
CP. However, when cranial nerve dysfunction was present, our patients with CP had
a higher incidence of temporary feeding tube dependence. Overall, 98% of patients
were able to resume oral nutrition.
