it seems both options are correct
NERVE REPAIR. The process of connecting two cut ends of a nerve is called neurorrhaphy, or nerve anastomosis. Peripheral nerves are composed of bunches of nerve fibers called fascicles that are enclosed by a layer called the perineurium; the epineurium is the outer layer of the nerve that encases the fascicles. Nerve repair may involve suturing of the ***epineurium only, ***the perineurium only, or through ***both layers.
Many of the techniques used for blood vessel anastomoses are also used for nerves. The cut ends of the nerve are exposed, then isolated from surrounding tissues. The ends are trimmed so that healthy nerve tissue is exposed, and a piece of contrast material placed behind the nerve for better visualization. Each nerve end is examined to determine the pattern of fascicles; the nerve ends are then rotated so that the fascicle patterns align. Sutures may be placed around the circumference of the epineurium; this is called epineurial neurorrhaphy.
***The perineurium of each cut fascicle end may be stitched with excess epineurium removed (perineurial neurorrhaphy), or both layers may be sutured (epiperineurial neurorrhaphy).
