The Art of Muscle Biopsy in the New Genetic Era: A Narrative Review.
Muscle biopsy has been practiced as a well-established part of paraclinical workup in patients with neuromuscular diseases since late 1960s. In this narrative review paper, the role of some pre and post muscle biopsy factors and their importance in achieving the best diagnostic results will be explained. Considering the new advances in diagnostic molecular techniques and the availability of local standard myopathology laboratory as well as the presence of a dedicated myopathologist, the indications of muscle biopsy in four major types of neuromuscular diseases will be shortly reviewed. Moreover, indications of muscle biopsy in four major types of neuromuscular diseases will be shortly discussed based on literature review of recent published diagnostic algorithms and our 11 years' experience of performing about 4000 muscle biopsies cases in the only standard referral diagnostic center for muscle biopsy in Iran. Although diagnostic algorithms of some muscle diseases have been changed based on recent advances in biochemical and molecular diagnostic techniques, still muscle biopsy continues to play a major role in the diagnosis and management of variety of neuromuscular disorders and has proved to be a preferable diagnostic procedure by some neuromuscular specialists for the cases who can benefit from rapid therapeutic management. The application of diagnostic algorithms should be practiced in accordance with geographic distribution of the diseases, the availability of diagnostic techniques and the presence of specialists in each center considering the local insurance coverage and the cost to be paid by the patient in every center.
