Abstrakt:	Head and neck rhabdomyosarcoma (HNRMS) is a rare type of soft tissue tumor that affects both adults and children with an overall incidence of 0.041 per 100,000 people. Adults make up approximately 31.2% of all HNRMS diagnoses and have an overall survival rate between 20% and 40%. We present a case of a 46-year-old male who initially presented with nasal congestion and vision changes. Maxillofacial computed tomography and magnetic resonance imaging of the brain showed involvement of the orbital apex, abutment of the planum sphenoidale, and extension to the foramen rotundum (FR). Nasal endoscopy with biopsy confirmed the diagnosis of T2aN0M0 parameningeal HNRMS. The patient underwent induction chemotherapy, followed by endoscopic resection, which resulted in negative intraoperative margins. Subsequently, he underwent adjuvant concurrent chemotherapy and proton beam radiation after positive microscopic positive margins were found on the optic nerve. The patient did not experience any significant complications, and he is currently without radiographic or clinical recurrence 18 months after the treatment. He was able to maintain his vision throughout the treatment. In adults, HNRMS is usually treated with chemoradiotherapy based on pediatric protocols, since there are limited data available for adult treatment protocols and outcomes. Although surgery has been associated with positive outcomes in adult patients, there are no previous reports of its use with either neoadjuvant or adjuvant treatment. This type of treatment protocol has never been described for adult HNRMS. We hope that our report can add more data to the growing body of literature on HNRMS treatment protocols.
