Sebaceous cyst after a certain recurrence rate. The reason is mostly due to the operation of the cyst wall is not completely removed. In particular, the recurrence of infection of the cyst, the cyst wall is thin, easy to peel the outer wall and epidermis adhesions, and facial parts of the cyst in order to retain the skin and peel is not complete, causing the residual wall and recurrence. I designed the epidermis and dermal or subcutaneous tissue injection of anesthetic, stripping the cyst can avoid the above ills. Are introduced as follows: 1. Surgical indications Where diagnosed sebaceous cyst, local inflammation can be implemented in this Act. 2. Surgical methods routine disinfection, shop sterile hole; take local anesthesia syringes and liquid medicine, in the cyst surface of the skin into the needle, the tip into the epidermis and dermis or subcutaneous tissue between the needle to the outer wall of the cyst and the skin or skin Tissue, injection of 0.5% procaine hydrochloride ml, to the epidermis and cyst outer wall was filled with liquid medicine
