Canthotomy is a surgical procedure primarily performed at the lateral canthus, which is the outer corner of the eye. This procedure is indicated to alleviate pressure and swelling that may occur in the eye, often as a result of trauma. The technique involves a series of steps that begin with the application of a hemostat to the skin at the lateral aspect of the eye. This action serves two purposes: it helps to achieve hemostasis, which is the cessation of bleeding, and it also marks the intended line of incision. Following this, the hemostat is released, and forceps are utilized to elevate the skin surrounding the lateral aspect of the eye, allowing for better access to the underlying structures. The incision is then made with scissors, starting at the lateral canthus and extending outward from the eye. In cases where the initial incision does not adequately relieve the pressure and swelling, the procedure may involve exposing and dividing the lateral canthus tendon. The incision is intentionally left open to facilitate the reduction of pressure and swelling in the affected area, promoting healing and recovery.
