Dermotomia

Dermotomia is a medical term that denotes an incision into the skin (derma) with a cutting action (tome or tomia). In practice, it is used to describe a surgical procedure in which the integument is incised to expose underlying tissues or to create access for treatment, biopsy, graft harvesting, or release of constrictions. The term is not common in contemporary clinical use; most clinicians describe the procedure as a skin incision or specify the operation (for example, biopsy, excision, fasciotomy, or graft harvest). Its usage is more likely to be found in historical texts, veterinary medicine, or in some European medical languages.

Procedure and technique: As with any incision, dermotomia is performed under sterile conditions with local or general anesthesia as appropriate. The surgeon marks the incision along planned lines, preserves skin edges for closure, and dissects through the epidermis and dermis to reach the target tissue. After completing the underlying work, the wound is closed in layers and dressings applied; closure may involve sutures, staples, or adhesive techniques. The exact depth and orientation depend on the intended access and anatomic considerations.

Risks and alternatives: Risks include infection, bleeding, scarring, nerve or vessel injury, and delayed healing. Alternatives focus on less invasive access routes when feasible or on non-incisional techniques such as needle biopsy or punch biopsy, depending on diagnostic needs.
