The following are some simple ways to distinguish between right-sided and left-sided slanting neck: 1. Touch the muscles on both sides of your neck to see on which side you can touch the spastic muscles and stiff tissues, then most likely there is slanting neck on this side. 2. Look in the mirror to see which side your head is slanting to. If the distance between the occiput and the shoulder on one side is significantly reduced, then the head is tilted to this side and there is a sloping neck on this side. 3. observe to which side one’s face is tilted, if one’s face is habitually tilted to one side, then there is often a sloping neck on the opposite side. 4. have someone else observe from behind to which side one’s cervical spine is tilted, to which side the cervical spine is tilted, there is most likely a sloping neck on which side. Of course, if the patient can’t tell which side of the slanting neck exists through the above ways, he or she can also go directly to the orthopedic department of a secondary or higher hospital and ask the doctor to help determine it.
