Diagnosis of Maxillary Sinus Cancer
Basis for the Diagnosis of Maxillary Sinus Cancer
1.Assessment of clinical symptoms and medical history
Focus on unilateral nasal obstruction, blood-tinged nasal discharge, facial numbness, and a history of occupational exposures.
2.Nasal endoscopy
Direct visualization of the tumor with acquisition of biopsy specimens is a key diagnostic step.
3.Computed tomography
The preferred method for evaluating destruction of the sinus walls and clearly delineating the extent of bony invasion.
4.Magnetic resonance imaging
Provides precise assessment of soft tissue extension, including involvement of the orbit, skull base, and nerves.
5.Histopathological biopsy
The gold standard for definitive diagnosis, determining tumor type and degree of differentiation; multidisciplinary or expert consultation is recommended.
6.Molecular pathology and special examinations
Immunohistochemistry and/or genetic testing can assist in diagnosing tumors that are difficult to classify.
7.Systemic staging evaluation
Assesses cervical and distant metastasis; commonly uses ultrasonography, CT, and PET-CT.
8.Ultrasound-guided needle biopsy
Navigation techniques enable accurate targeting and improve the safety of biopsy for deep-seated lesions.
9.Daily self-check for maxillary sinus cancer
Monitor for changes such as facial asymmetry, unilateral nasal obstruction, and blood-streaked mucus on postnasal expectoration.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that delayed diagnosis of maxillary sinus cancer can have severe consequences. Individuals should be vigilant for unilateral facial symptoms and undergo timely nasal endoscopy, imaging, and pathological biopsy. Accurate staging and molecular subtyping are prerequisites for individualized treatment, functional preservation, and improved survival rate.
