title: Epidermal inclusion cysts following minimal incision surgery.
abstract: One of the most frequent causes of epidermal inclusion cysts is trauma involving the epidermis with subsequent implantation of epidermal cells into the dermis or subcutis. Minimal incision surgery is capable of achieving this because it is performed by using small incisions and rapidly rotating power instruments. The technique requires that the surgeon master a high degree of dexterity and knowledge of the anatomy without the aid of direct visualization. Van Enoo and Cane suggest the use of fresh, sharp skin blades to protect against invagination of skin edges which could lead to epidermal inclusion cysts. They also state that an improper position or an incision that is too small will cause tension, which can lead to heat buildup with subsequent sloughing and dehiscence. It may also drive some epidermal cells underneath the dermis and foster an epidermal cyst. Other surgeons using small incisions suggest thorough and copious irrigation to flush away debris and to avoid potential foreign body reactions. The periosteum should be reflected away from the point where the drill bit exits the bone to prevent bone chips from being forced subperiosteally and potentially causing a foreign body reaction. By virtue of the technique, minimal incision surgery lends itself to a greater risk of causing epidermal inclusion cysts. Surgeons who use these techniques must be aware of this potential complication.
