Hematoma
What is a Hematoma?
A hematoma is a localized accumulation of blood that has pooled outside of blood vessels following trauma to the tissue. In combat sports, hematomas most commonly form around the orbital area, the region surrounding the eye, as a result of repeated impact to the face. The broken capillaries beneath the skin bleed into the surrounding tissue, causing the characteristic raised, firm swelling that can close a fighter's eye within a few rounds if left untreated.
Why Hematomas Matter in Combat Sports
A hematoma near the eye is one of the primary reasons fights get stopped by referees and ringside physicians. When swelling closes a fighter's eye, their field of vision narrows significantly, creating a safety risk and a competitive disadvantage serious enough to justify a stoppage.
The cutman's job is to prevent that outcome. Between rounds, the cutman applies cold direct pressure using an enswell, a flat, chilled metal tool pressed firmly against the swollen area, to constrict the vessels and limit further pooling of blood.
What Not to Do
One of the most persistent myths in corner work is that rubbing or massaging a hematoma will help disperse it away from the eye. It will not. Rubbing disrupts the microscopic blood vessels beneath the skin, increasing bleeding and making the swelling worse. Cold, firm, direct pressure is the correct intervention.
Types Relevant to Combat Sports
Orbital hematoma: The most common type in boxing and MMA. Forms around the eye socket, often referred to informally as a mouse or egg. Managed with the enswell and cold pressure.
Septal hematoma: Forms inside the nasal septum following a hard blow to the nose. Requires different management and, if left untreated outside of competition, can lead to serious structural complications.
Subdural hematoma: A more serious medical condition involving bleeding inside the skull, between the brain and its outer covering. This is a medical emergency and falls outside the scope of ringside cut work entirely.
In the Broader Martial Arts Context
Hematomas are not exclusive to boxing. They occur in Muay Thai, MMA, kickboxing, judo, and any full contact discipline where impact to the face and body is part of the sport. The principles of management, cold pressure, elevation, avoiding further trauma, are consistent across disciplines.
