Orbital Fracture

An orbital fracture is a broken bone in the area of the eye socket, the bony cavity that surrounds and protects the eye. The eye socket consists of several thin bones, of which the floor and the inner (medial) wall are the most susceptible to fracture. Orbital fractures result from direct force and can occur at any age. In children, certain types of fracture require particular attention.

Causes

  • Falls (particularly common in children)
  • Sports injuries (e.g. from a ball, an elbow or a racket)
  • Road traffic accidents
  • Blows and other forms of violence

A particular point in children: the trapdoor fracture

In children the orbital bones are more elastic than in adults. What is known as a "trapdoor fracture" can occur: the bone breaks, flaps open and traps eye muscle tissue before closing again. This trapped tissue has to be freed surgically within hours, in order to avoid permanent eye movement disorders and double vision. A trapdoor fracture is an ophthalmological emergency.

Symptoms

  • Swelling and bruising around the eye
  • Pain, particularly on eye movement
  • Double vision
  • Numbness of the cheek, upper lip or teeth
  • Restricted eye movement (the eye cannot look in all directions)
  • Sunken eye (enophthalmos), sometimes only visible once the swelling has subsided

Swelling and Double Vision After a Fall

After a fall or sports accident with swelling around the eye, double vision or limited eye movement, acting quickly is important, especially in children. Call us and we will assess how urgent the examination is. For follow-up checks of eye motility, Dr. Stefan Langenegger and orthoptist Edona Desku are there for you in the center of Zurich on Bahnhofplatz.

Diagnostic work-up

  • Clinical examination: assessment of eye movement, pupil reaction and vision
  • Computed tomography (CT): the most important imaging method for showing the fracture and any tissue entrapment precisely

Treatment

Conservative treatment

Most simple orbital fractures heal without surgery. The following are recommended:

  • Cooling the affected area
  • Decongestant nasal drops
  • Not blowing the nose (air can otherwise enter the orbit and make the swelling worse)
  • Pain medication and antibiotics where needed
  • Regular follow-up examinations

Surgical treatment

Surgery is necessary in the case of:

  • Trapdoor fractures with trapped tissue (urgent)
  • Persistent double vision due to tissue entrapment
  • A clearly sunken eye (enophthalmos)

Trapped soft tissue is released and, where needed, the bone is stabilised with an implant.

Follow-up

After an orbital fracture, regular check-ups with the ophthalmologist are important. Eye movement is monitored and it is checked whether the double vision resolves. In some cases a squint can remain after healing, which may need further treatment.

When should you see a doctor immediately?

With an injury to the facial area accompanied by swelling around the eye, double vision or restricted eye movement, you should attend an emergency department or ophthalmology practice without delay. In children in particular, acting quickly is crucial in order to rule out a trapdoor fracture.
