Head stitches have no effect on CT, but when the head is traumatized, a head CT should be performed to determine if there is any damage to the brain. Head stitches are usually caused by scalp trauma, and the threads of the head stitches will not affect the CT, nor will they produce artifacts on the head CT examination. Head CT does not affect the future healing of the head stitches. When a head injury occurs, a CT scan of the head should be ordered by the doctor to determine if there is any damage to the brain or skull. If there is damage, the location and extent of the damage should also be clarified. This will guide the clinical treatment. When head trauma should immediately go to the hospital, under the guidance of the doctor to improve the auxiliary examination.
