How Is a Muscle Biopsy Performed?

A muscle biopsy can be performed using two main techniques: open biopsy and needle biopsy.

  • Open Biopsy: This is a surgical procedure where a small incision is made in the skin to expose the muscle. A piece of muscle tissue is then removed. This method provides a larger sample for analysis.
  • Needle Biopsy: A less invasive procedure where a needle is inserted through the skin into the muscle to remove a small tissue sample. This method is quicker and involves less recovery time but may not provide as large a sample as an open biopsy. The choice of technique depends on the specific condition being investigated and the location of the muscle.
