Endoscopic-assisted low-temperature plasma resection of tongue root schwannoma via oral approach: a case report and literature review

This article reports a case of a 17-year-old male pediatric patient whose imaging and fiberoptic nasopharyngoscopy examinations initially suggested an oropharyngeal malignant tumor. The patient underwent endoscopic-assisted low-temperature plasma surgical excision of the tongue root schwannoma via oral approach, a minimally invasive method well-suited for pediatric patients, and achieved excellent therapeutic outcomes with no postoperative complications or tumor recurrence. This case provides critical clinical reference for the diagnosis and treatment of tongue root schwannomas in children and adolescents, addressing an unmet need in pediatric head and neck care.
