Basis for Parotid Gland Cancer Diagnosis
1.Clinical presentation assessment
A detailed medical history and head and neck examination are performed to evaluate mass characteristics and facial nerve function.
2.Ultrasonography
Used for initial assessment of cystic versus solid lesions, and to guide needle biopsy to clarify lesion nature.
3.CT examination
Delineates tumor extent, vascularity, and cervical lymph nodes, assisting surgical planning.
4.MRI examination
Provides high soft-tissue contrast and clearly demonstrates the relationship between the tumor and the facial nerve and vessels.
5.Pathological biopsy
Fine-needle aspiration or incisional biopsy is the gold standard for confirming tumor type and grade.
6.Molecular diagnostic techniques
Genetic alteration testing assists subtyping and prognostic assessment and guides individualized treatment.
7.Intraoperative nerve monitoring
Enables real-time identification and protection of facial nerve branches, reducing postoperative complications.
8.Systemic evaluation
Chest CT and other studies are used to screen for distant metastasis and complete accurate disease staging.
9.Daily self-check for parotid gland cancer
Monthly, observe facial symmetry in the mirror and palpate the periauricular and submandibular regions for masses; seek medical attention promptly if numbness or facial deviation is noted.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that parotid gland cancer tends to invade the facial nerve, making early recognition and standardized diagnosis and treatment pivotal. Regular self-checks and vigilance for facial masses, together with MDT-based multidisciplinary collaboration, enable individualized therapy and improve prognosis and quality of life.
