Abstract
AbstractPathological diagnosis plays a pivotal role in risk classification and personalized treatment planning for patients with oropharyngeal cancers. However, challenges arise in cases involving trismus and tumors with submucosal spread, hindering traditional endoscopic biopsies and open incisional biopsies. In this study, we examined the clinical and pathological data of patients with trismus who underwent transoral ultrasound‐guided core biopsy (USCB) for their oropharyngeal tumors, comparing this method with existing diagnostic approaches. Seventeen patients presenting with oropharyngeal tumors and trismus underwent transoral USCB for diagnosis. Of these, 14 patients were diagnosed with squamous cell carcinoma, while the remaining 3 were diagnosed with lymphoma. The procedure resulted in minimal wound size and effective bleeding control through compression, without encountering any complications. In conclusion, transoral USCB emerges as a precise diagnostic tool for patients with oropharyngeal tumors and trismus, offering a valuable adjunct to conventional open and endoscopic biopsies.
