Participants were asked to identify whether they (A) could independently perform each procedure, (B) could perform each procedure with the assistance of a senior doctor, or (C) were unable to perform each procedure. Those whose response was (A) were asked how many surgeries were required to acquire the necessary skills. Those who responded to (B) or (C) were asked how many surgeries they believed were required to acquire the skills necessary to operate independently. Participants also responded to 10 questions on surgical training techniques and rated the usefulness of each method.Results: A total of 55 spine surgeons responded to the questionnaire. Group A required significantly fewer surgeries in the following categories to become independent than required Group C: upper cervical spine surgery (7.3/19.3), anterior cervical decompression/fusion (6.7/28.8), posterior cervical decompression/fusion (9.5/27.3), lumbar discectomy (12.6/26.7), endoscopic lumbar discectomy (10.2/24.2), spinal tumor resection (6.5/37.2), and spinal kyphosis surgery (10.3/32.3). Over 80% of participants responded that the following were effective methods: “surgeries where a senior doctor is the main surgeon, and the respondent is the assistant and observer”; “surgeries where the respondent is the main surgeon, and a senior doctor is an assistant”; “self-study using surgery manuals, articles, and textbooks”; and “training through video surgery sessions”.Conclusion: Surgeons who do not perform specific procedures independently require more surgical experience than those who operate independently. Our results may help develop more efficient training methods for spine surgeons.Keywords: surgical experience, surgical training, training system, inexperienced spine surgeons

A 50-year-old man presented to the clinic with severe neck pain, fever, and difficulty breathing and was subsequently admitted to the local orthopedics department with possible retropharyngeal abscess and pyogenic spondylitis. Antibiotic therapy was initiated; however, due to poor oxygenation, he was referred and transferred to our department and admitted. Magnetic resonance imaging showed signal changes at the left C1/2 lateral atlantoaxial joint, posterior pharynx, longus colli muscle, carotid space, and medial deep cervical region, predominantly on the left side. In addition, despite lymph node enlargement from the posterior pharynx to the deep cervical region, there was no abscess formation. There were no signs of a space-occupying lesion or signal changes in the jugular foramen. One day postadmission, the patient’s temperature had risen to 39.1°C and his SpO2 had fallen. His neck pain had also worsened, and emergency surgery was decided. Preoperatively, we suspected retropharyngeal abscess and pyogenic spondylitis. On day 13 postadmission, the patient exhibited dysphagia, deviated tongue protrusion, and the curtain sign. Glossopharyngeal and hypoglossal nerve paralysis were diagnosed. The patient’s swallowing functions recovered and he was discharged on day 36. We experienced a case of glossopharyngeal and hypoglossal nerve paralysis secondary to pyogenic cervical facet joint arthritis.
