ABSTRACT
Objective:To explore the value of ultrasound fusion navigation technology in the biopsy of parapharyngeal-infratemporal fossa-skull base (PIS) lesions.Methods:This study was conducted at the First Affiliated Hospital of Sun Yat-Sen University from March 2021 to March 2022 and included 8 patients [3 females and 5 males; age, (50±20) years; range, 16-76 years] with PIS lesions who needed to clarify the pathological diagnosis. The ultrasound fusion navigation with CT or MRI was used to guide lesion biopsy, and the technical feasibility, pathological diagnostic results and complications were evaluated.Results:The biopsy procedures were successful in all 8 patients, and the lesion size ranged from 2.2 to 6.5 cm. The exact pathological diagnosis was obtained in 7 patients, and the diagnostic rate was 87.5% (7/8). No major complication was observed after the biopsy. Mild complications occurred in 1 case, with a incidence of 12.5% (1/8).Conclusions:Ultrasound fusion navigation-guided biopsy is feasible, effective, and safe in the biopsy of deep head and neck lesions.
