Objective: To analyze the timing of the early postoperative computed tomography (CT) in traumatic brain injury (TBI) patients, and compare CT and neurological examination (NE) findings.
Methods: Retrospective analysis included 353 TBI patients admitted to two level 1 trauma centers (2016-2020) who underwent head surgery and postoperative CT within 24 h. Analyzed variables: age, Injury Severity Score (ISS), Glasgow Coma Score (GCS), Abbreviated Injury Scale head (AISh), comorbidities, CT and NE findings and timing, head surgery type, and mortality.
Results: Patients mean age was 61.9 years, ISS 25.1, GCS 11.0, AISh 4.7. Postoperatively, mean time to first positive CT was 6.1 h and to first positive NE was 13.2 h. Positive CT alone was more accurate in identifying need for 2nd head surgery than positive NE alone (21.8 % vs 6.0 %, p = 0.04). There was no difference between patients with CT done earlier than 6 h compared to patients with CT done after 6 h in mortality (26.1 % vs 22.0 %, p = 0.4) or 2nd surgery rate (12.2 % vs 12.2 %, p = 1.0). Reversal of postoperative CT findings occurred in 1/6 of patients and was more common when CT was done earlier than 6 h compared to CT done later (25.7 % vs 0.8 %, p < 0.001). Early CT within 1 h rarely leads to the change of management but often is followed by another CT within 12 h.
Conclusion: In TBI patients postoperative CT was more effective than NE in predicting a need for 2nd head surgery. Postoperative head CT at 6 h is recommended to allow timely detection of intracranial deterioration, reduce the number of CTs and reversal findings as it does not increase 2nd surgery rates and mortality.

The use of extracorporeal membrane oxygenation (ECMO) in surgery is expanding as the medical community started adopting it, with good results, for procedures with high risk of respiratory and hemodynamic instability. This technique provided the possibility to reduce the number of patients previously considered inoperable because of these limitations. Thymic epithelial tumors (TETs) are rare neoplastic mediastinal lesions, with a reported incidence of 0.

Background: In 2024, the Korean Ministry of Health and Welfare enforced a policy to increase the number of medical school students by 2,000 over the next 5 years, despite opposition from doctors. This study aims to predict the trend of excess or shortage of medical personnel in Korea due to the policy of increasing the number of medical school students by 2035.
Methods: Data from multiple sources, including the Ministry of Health and Welfare, National Health Insurance Corporation, and the Korean Medical Association, were used to estimate supply and demand.

Objective: Intraoperative systems for monitoring facial nerve function, in which temporal electrical stimulation is applied to the facial nerve through electrodes, are used in many surgeries requiring facial nerve preservation; however, continuous stimulation or quantitative evaluation of facial nerve function is difficult with this approach. We examined the usefulness of a continuous and quantitative facial nerve-monitoring system for temporal bone lesions by using our experience to modify the existing methods used for cases involving vestibular schwannomas.

Purpose: The escalating number of endoscopic skull base procedures necessitates exploring additional materials to reduce postoperative cerebrospinal fluid (CSF) leaks in revision or staged surgeries. This study evaluates the effectiveness of reused nasoseptal flaps (NSFs) in such clinical scenarios.
Methods: A retrospective review was conducted on patients who previously underwent surgery involving NSFs and later had revision or secondary skull base surgeries via endoscopic endonasal approaches (EEAs) at a tertiary medical center.

Purpose: Sarcopenia, characterized by loss of skeletal muscle mass (SMM) and strength, often leads to dysphagia in the elderly. This condition can also worsen treatment outcomes in head and neck cancer (HNC) patients, who are susceptible to swallowing difficulties. This study aimed to establish the correlation between swallowing muscle mass (SwMM) and SMM in HNC patients.
