Jugular foramen paragangliomas are rare skull base tumours posing multiple complex diagnostic and management problems. We did a study to evaluate surgical technique, outcome and complications in 75 cases of tumours treated by multidisciplinary approach (i.e. combined neurosurgery, neuroradiology, ear, nose and throat surgery and intensive care unit team). Retrospective study on 75 consecutive patients with jugular foramen paragangliomas treated surgically from 1989 to 2005. Preoperative balloon occlusion test was performed in all patients as well as embolization (100%). A combined limited infratemporal and juxtacondylar approach was used in all patients. Gross total resection was achieved in 59 patients (78.7%). The most common complication was represented by lower cranial nerve deficits in five patients (6.6%), which was only temporary in three. Postoperative facial nerve weakness occurred in five cases (6.6%) and resolved in three of them. The remaining two patients underwent facial nerve reconstruction by hypoglossal/facial nerve anastomosis. Four patients (5.3%) had a postoperative cerebrospinal fluid leak, which was successfully treated by lumbar drainage. Two patients (2.7%) died because of complications related to surgical injury of lower cranial nerves: one patient developed aspiration pneumonia and septicemia and the second one developed a large cervico-bulbar hematoma that led to severe respiratory distress and ultimately global cerebral hypoxia. Paragangliomas are rare and complex skull base lesions that may be managed with low morbidity and mortality if a multidisciplinary approach is considered. Facial and lower cranial nerve postoperative deficits can be limited.

The aging of the population in westernized countries constitutes an important issue for the health systems struggling with limited resources and increasing costs. Morbidity and mortality rates reported for neurosurgical procedures in the elderly vary widely. The lack of data on risk benefit ratios may result in challenging clinical decisions in this expanding group of patients. The aim of this paper is to analyze the elderly patients cohort undergoing neurosurgical procedures and any trend variations over time. The medical records of elderly patients (defined as an individual of 70 years of age and over) admitted to the Neurosurgical and Neuro-ICU Departments of a major University Hospital in Paris over a 25-year period were retrospectively reviewed. The analysis included: (1) number of admissions, (2) percentage of surgically treated patients, (3) type of procedures performed, (4) length of hospital stay, and (5) mortality. The analysis showed a progressive and significant increase in the proportion of elderly presenting for neurosurgical elective and/or emergency procedures over the last 25 years. The number of procedures on patients over 70 years of age increased significantly whereas the mortality dropped. Though the length of hospital stay was reduced, it remained significantly higher than the average stay. The types of procedures also changed over time with more craniotomies and endovascular procedures being performed. Age should not be considered as a contraindication for complex procedures in neurosurgery. However, downstream structures for postoperative elderly patients must be further developed to reduce the mean hospital stay in neurosurgical departments because this trend is likely to continue to grow.
