Long-term results of surgery for temporal bone paragangliomas.
OBJECTIVE
Assessment of the long-term results of surgery for temporal bone paragangliomas with special consideration of the patient's ability to cope with the functional deficits.


METHODS
Retrospective review of 36 patients who had undergone resection of a temporal bone paraganglioma 10 to 15 years previously. Assessment of the patients' subjective view of the functional outcome and quality of life by a questionnaire.


METHODS
Clinical records were reviewed regarding size of tumor, technique of surgery, supportive therapy, and tumor recurrence. Patients were sent a 50-item questionnaire evaluating their quality of life and the preoperative and postoperative function of cranial nerves VII through XII.


RESULTS
A complete tumor removal was achieved in 30 patients (83%). There was only one tumor recurrence. The major negative effects of surgery involved hearing and dysphagia, which deterioriated in 14 and 12 patients, respectively. Thirty-five of the 36 patients (97%) reported that, despite deterioration, the cranial nerve deficits were still acceptable. Seventy-five percent of the patients regained their preoperative quality of life and 97% returned to their previous occupation in 1 to 2 years.


CONCLUSIONS
The otologic extradural approach allowed complete tumor removal in 83%, with minimal perioperative morbidity. No surgically induced central nervous system lesions occured. Tracheostomy was avoided and all patients resumed oral feeding. Full rehabilitation after removal of class C and CD paragangliomas may take 1 to 2 years. However, the fact that 97% of the patients finally resumed normal social life showed the ability of most patients to cope with the sequelae of surgery even in class C and CD paragangliomas.
