Drainage from Face or Head
Summary
The head is unusual because of the very thin skin covering over bone. Wounds to the head can fracture the skull, or can simply scrape off the protective covering (periosteum) of a section of bone. Either situation can result in bone that has lost its blood supply. This piece becomes isolated, dies, and acts as a foreign body. Technically, this is called a sequestrum, and this unhealthy bone must be removed in order for a wound to heal and drainage to stop.
Bacterial infection can abscess and break open and drain pus as well. The classic example of this is Strangles (Streptococcus equi equi) infection, but other types of infections in the face can do this as well. There is usually very little smell associated with Strangles drainage. Oral foreign bodies can abscess and drain.
Under the base of the ear, Dentigerous Cyst can appear as a small draining tract, little swelling and crusting of honey-like secretion.

What To Do
First, recognize the signs of Strangles. If there is risk of Strangles, your first job is to quarantine the horse and prevent spread of disease to others. Wear latex gloves when assessing wounds and drainage of the face.Perform the Whole Horse Exam, paying particular attention to the location, odor and appearance of the drainage. Rectal temperature, heart rate, attitude and appetite (ability to chew and eat) are important. Notice whether there is swelling surrounding the drainage.
Notice whether there is respiratory noise. If you can safely do it, look in the mouth for wounds or foreign bodies.
You can clean the wound off gently, apply an antibiotic ointment, until your vet can assess the horse.

your vet's role
In many cases your vet will conduct a quick clinical exam. Sometimes, diagnostic tests may be needed. Radiography is used to diagnose fractures, dead bone, sinusitis and infected teeth. Ultrasound occasionally can be helpful to locate foreign bodies, abscesses and fractures. Bacterial culture can sometimes be needed to rule out Strangles.
