Attic cholesteatomas can be exenterated by transcanal endoscopic ear surgery (TEES). In the limited operative field of exclusive transcanal endoscopic atticotomy, surgeons use either a piezosurgery scalpel or a drilling system to remove the posterior lateral bony wall of the epitympanum. We aimed to investigate the feasibility of using piezosurgery or microdrill for endoscopic atticotomy during exenteration of attic cholesteatomas. ⋯ Endoscopic atticotomy performed using a piezosurgery scalpel is potentially safer but slower than using a microdrill for exenteration of attic cholesteatomas.

Hypothalamic invasion in pediatric patients with craniopharyngioma negatively influences clinical outcomes. It has been shown that radiologic classification of hypothalamic invasion can effectively predict surgical strategies to minimize postoperative comorbidities in pediatric patients. However, no comparative analysis has been performed in adult patients with craniopharyngioma. This study implements the previously established radiologic classification to characterize postoperative morbidity, surgical outcome, and distress in adult patients with craniopharyngioma. ⋯ Our results point toward a possible predictive role of preoperative hypothalamic invasion for postoperative diabetes insipidus as well as higher perceived levels of distress after surgery, which may be established in larger patient cohorts. Furthermore, a subfrontal surgical approach seems to be predicted by tumors with hypothalamic invasion. In this case, preoperative magnetic resonance imaging grading may help guide the planning of an optimal surgical strategy for adults with craniopharyngioma to reduce postoperative morbidity.

Hypernatremia is a treatable biochemical disorder associated with significant morbidity and mortality in patients undergoing surgery. However, its impact on patients who undergo elective craniotomy is not well understood. This study aimed to investigate the prognostic implications of postoperative hypernatremia on the 30-day mortality of patients undergoing elective craniotomy. ⋯ Hypernatremia is common after elective craniotomy, and its presence is associated with increased mortality and complications, particularly in cases of severe hypernatremia. These results emphasize the significance of risk evaluation in neurosurgical patients and propose the advantages of closely monitoring serum sodium levels in high-risk individuals. Future randomized controlled trials could provide more insight into the effect of treating postoperative hypernatremia in these patients.

Advances in surgical practices have decreased hospital length of stay (LOS) after surgery. This study aimed to determine the safety of short-stay (≤24-hour) left colectomy for colon cancer patients in the US. ⋯ Although currently performed at low rates in the US, short-stay left colectomy is safe for a select group of patients. Attention to patient selection, refinement of clinical pathways, and close follow-up may enable short-stay colectomies to become a more feasible reality.

Brain metastases (BM) develop in nearly half of the patients with advanced melanoma. The aim of this retrospective historical cohort study was to analyze radiological response of melanoma BM to single-fraction Gamma Knife radiosurgery (GKRS), in relation to biologically effective dose (BED) for various alpha/beta ratios. ⋯ BED Gy 10 and particularly Gy 15 were more statistically significant than physical dose for LC after GKRS for radioresistant melanoma BM. Irradiation time (per lesion) longer than 40 minutes was predictive for lower rates of LC. Such results need to be validated in larger cohorts.
