In the paper the authors present the evaluation of head and neck rhabdomyosarcoma (RMS) treatment in 14 children admitted to Pediatric Institute in the past 25 years. The treatment was related to the stage of the neoplasm at the time of diagnosis and consisted in the surgical intervention combined with chemo- and radiotherapy. Embryonal stage was diagnosed in 10 children (71.4%) and alveolar stage in 4 children (28.6%). In the analysed material primary neoplastic changes were found: in 6 cases in the orbit, in 2 cases in the maxillary sinus and nasal cavity, in 2 cases in the mandible. We noted also 1 case in each of the following structures: the nasopharynx, the palate, the pterygoideo-palatal fossa, the neck. In the years 1973-1991--7 children were treated according to the IRS I and II projects. Three of the children presented with the third stage of neoplastic disease and the rest with the second. Between the years 1991-1997--7 other children were hospitalized and underwent treatment based on CWS-91 project. Six of them showed the third stage of neoplasm, and only one--the first. The performed analysis revealed the insignificant improvement in the effectiveness of the treatment after the introduction of the CWS-91 project.

Research Institute for Healthcare Policy, Korean Medical Association, Yongsan-gu, Seoul, South Korea.
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.

Optimizing skull base defect repair: leveraging the reused nasoseptal flap as a reliable material.
Eur Arch Otorhinolaryngol
January 2025
Department of Otolaryngology-Head and Neck Surgery, Taipei Veterans General Hospital, Taipei, Taiwan.
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.
Unveiling the relation between swallowing muscle mass and skeletal muscle mass in head and neck cancer patients.

Department of Otorhinolaryngology, Head and Neck Surgery, University Medical Center Groningen, University of Groningen, Hanzeplein 1, PO box 30.001, Groningen, 9700RB, The Netherlands.
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.
