Case Report: transcavernous sinus resection of parotid carcinoma with perineural invasion to Meckel’s cave and cavernous sinus

This case demonstrates that even extensive cavernous sinus invasion by parotid ACC can be safely addressed with curative intent through precision-based microsurgery. A modified Dolenc approach with limited bone work and infratemporal extension enables maximal resection while preserving function. Strategic reconstruction optimizes safety for adjuvant radiation. This report adds to the growing evidence supporting aggressive yet function-preserving surgical management of malignant skull base tumors in multidisciplinary oncology programs.
