Subdermal

Subdermal refers to something situated or occurring beneath the dermis, which is the thick layer of skin that forms the true skin, located between the epidermis (outermost layer) and the subcutaneous tissue (innermost layer). This position places subdermal elements within the skin but deeper than its surface. Medical applications often focus on this area for injections, implants, and cosmetic procedures due to its rich blood supply and accessibility compared to deeper tissues. The term is commonly used in anatomy, dermatology, and cosmetic surgery to describe the location of structures or processes relative to the skin's layers.

Subdermal meaning with examples

• A doctor injected a medication *subdermally* to ensure slow release and absorption into the bloodstream, allowing for prolonged therapeutic effects in treating a chronic illness. The slow, steady diffusion meant fewer peaks and valleys in the medication's impact, improving the patient's comfort and effectiveness.
• The subdermal implant contained sensors that monitored the athlete's vital signs during training sessions. The real-time data was crucial for assessing performance and minimizing the risk of injury. This continuous monitoring also provided feedback on training effectiveness.
• Following the accident, subdermal bruising was visible beneath the skin, indicating blood vessel damage. Imaging such as an MRI was required to visualize the extent of damage. Accurate assessment of the injured tissue was vital for making decisions on the best treatment option.
• Cosmetic surgeons used subdermal fillers to smooth wrinkles and add volume to the patient's face. These substances were strategically injected to target the areas in which they would improve the skin’s appearance and provide a lasting effect, improving the patient's quality of life.
• A subdermal hematoma, caused by a blunt force injury, caused discolouration and swelling underneath the surface of the skin. The haematoma needed treatment because it was applying pressure on the surrounding tissue and the injury caused considerable pain to the patient.
