Biopsy

Material

• Needle core biopsy typically uses a 2 mm diameter needle for tissue sampling, providing a good balance between diagnostic accuracy and patient comfort. This procedure is essential for diagnosing various oral pathologies. [Q4092]
• Needle/core biopsy provides a more definitive diagnosis than fine needle aspiration (FNA) due to its ability to obtain a larger tissue sample. This makes it a preferred method for diagnosing complex lesions. [Q4415]
• Needle/core biopsy uses a larger needle compared to fine needle aspiration (FNA), allowing for better tissue architecture preservation. This technique enhances diagnostic accuracy. [Q4416]
• For initial evaluation of parotid gland tumors, fine needle aspiration (FNA) or imaging techniques are typically preferred before considering an incisional biopsy. This approach minimizes invasive procedures. [Q4927]

Extraction Techniques

Complications
