Paramaxillary (Transfacial) Approach for CT-Guided Head and Neck Biopsies

Area of Science:

• Interventional Radiology
• Head and Neck Imaging
• Neurosurgery

Background:

• Deep-seated head and neck lesions pose biopsy challenges due to critical neurovascular proximity.
• Ultrasound visualization is often limited for these deep lesions.

Purpose of the Study:

• To demonstrate the paramaxillary approach as a safe and effective CT-guided biopsy technique.
• To provide a detailed roadmap for accessing challenging head and neck masses.

Main Methods:

• Detailed anatomical review relevant to the paramaxillary approach.
• CT-guided procedural demonstration with case examples.
• Discussion of indications, contraindications, and biopsy types (FNA vs. core biopsy).

Main Results:

• The paramaxillary approach provides a reproducible pathway to deep head and neck spaces.
• The technique facilitates precise tissue acquisition with potentially lower morbidity.
• Case examples illustrate anatomical landmarks, potential pitfalls, and success tips.

Conclusions:

• The paramaxillary approach is a valuable technique for interventional and neuroradiologists.
• It enables precise, low-morbidity biopsies of challenging deep head and neck lesions.
• This CT-guided method improves access to difficult-to-reach anatomical areas.
