Pneumocephalus with BiPAP use after transsphenoidal surgery

While the benefits of continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) for patients with obstructive sleep apnea are well described, reports in the literature of complications from its use are rare. A patient who received postoperative BiPAP after undergoing transsphenoidal craniopharyngioma resection developed severe pneumocephalus and unplanned intensive care unit admission. Although the pneumocephalus resolved with conservative management over two weeks, we propose caution in the use of CPAP postoperatively in patients undergoing procedures of the head and neck.

Outcomes of pediatric patients with malignancies of the major salivary glands

BACKGROUND

To report the outcomes and early to long term treatment complications among pediatric patients with major salivary gland malignancies treated at a single institution.

MATERIALS AND METHOD

This study was a retrospective case review set at a tertiary referral cancer center. Patients less than 19 years of age with a diagnosis of a major salivary gland malignancy were identified at the M. D. Anderson tumor database between 1953 and 2006.

RESULTS

A total of 61 patients were identified, with equal gender distribution. The majority of tumors arose in the parotid gland (83%), and the most common pathology was mucoepidermoid carcinoma (46%). Lymphatic metastasis was identified in 37% of patients, nearly all with mucoepidermoid carcinoma. Although 65% of patients had prior treatment elsewhere, more than 75% of patients underwent surgical resection at our institution. External beam radiation was used in 45% of patients, with an average dose of 58.6 Gray. Average patient follow-up was 153 months. The overall survival rate was 93% at 5 years, and 26% developed a recurrence. A second primary was identified in 2 patients. Permanent facial paresis was noted in 7 patients (12%) and xerostomia in 1 patient (4%).

CONCLUSIONS

Survival of pediatric patients with major salivary gland carcinomas is favorable. Adverse outcomes were best predicted by tumor grade, margin status, and neural involvement. Radiation therapy is beneficial for locoregional control of disease, with acceptable long-term treatment sequelae, and without a significant risk for developing second primary tumors. Survivorship issues need to be addressed in this patient population into adulthood.
