Assessing Risk of Severe Complications after Endoscopic Transnasal Transsphenoidal Surgery: A Comparison of Frailty, American Society of Anesthesiologists, and Comorbidity Scores.

 This study aimed to improve age-independent risk stratification for patients undergoing endoscopic transnasal transsphenoidal (TNTS) approach to pituitary mass resection by investigating the associations between frailty, American Society of Anesthesiologists (ASA), and comorbidity scores with severe complications following TNTS.  This study is a retrospective review.  This review was conducted utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

Iatrogenic Nontraumatic CPAP-Induced Pneumocephalus in a Patient With Meningitis.

Pneumocephalus, or air within the cranium, can be caused by trauma, intracranial infections, or tumors, and can also occur as a complication of neurosurgery and lumbar puncture. Continuous positive airway pressure (CPAP) therapy can precipitate or worsen pneumocephalus in cases of known head trauma. However, nontraumatic pneumocephalus being caused by CPAP is a highly unexpected clinical event.

Direct Tumor Embolization of Sinonasal Unclassified Spindle Cell Sarcoma with Onyx.

Objectives: To evaluate the use of a new tumor embolization agent, Onyx (Covidien, Dublin, Ireland), for the use of intraoperative embolization of a sinonasal unclassified spindle cell sarcoma.

Methods: A 45-year-old female patient presented to the rhinology clinic with a nasal mass. A biopsy revealed a highly vascular mass consistent with a sinonasal unclassified spindle cell sarcoma.
