The risk of surgery for a long stem protrusion is generally small, but the possibility of blood vessel or nerve damage cannot be ruled out. Stenosis is a spiny or angular bone that grows below the front of the temporal bone and protrudes into the neck. It is usually caused by congenital developmental abnormalities, and may present with symptoms such as difficulty in swallowing and pain in the pharynx. If the condition is more severe, surgery is required. Surgery usually involves some risk, but the risk of penile protuberance surgery is relatively small because the operation is relatively simple, and there are usually no accidents if all the examinations are done before the operation. However, as there are more blood vessels and nerves around the bulge, damage to blood vessels or nerves may occur. It is recommended that patients with long penile protrusion should go to the hospital for treatment in time to avoid aggravation of the condition. After the operation, pay attention to local cleanliness to prevent infection.
