ICD-10: S02.40

The ICD-10 code S02.40 refers to a fracture of the malar, maxillary, and zygoma bones that is unspecified. This classification falls under the broader category of injuries to the skull and facial bones, specifically addressing fractures in the facial region.

Clinical Description

Definition

The malar bone, also known as the zygomatic bone, is a key component of the facial skeleton, contributing to the structure of the cheek and the orbit of the eye. The maxillary bone forms the upper jaw and holds the upper teeth, while the zygoma is the bone that forms the prominence of the cheek. A fracture in these areas can result from various causes, including trauma from accidents, falls, or sports injuries.

Symptoms

Patients with fractures of the malar, maxillary, and zygoma bones may present with a range of symptoms, including:
- Facial Swelling: Swelling around the affected area is common due to inflammation and tissue injury.
- Bruising: Ecchymosis may appear on the face, particularly around the eyes (raccoon eyes) or cheeks.
- Pain: Localized pain at the fracture site, which may worsen with movement or palpation.
- Deformity: Visible changes in facial contour or asymmetry may occur, depending on the severity of the fracture.
- Functional Impairment: Difficulty in chewing, speaking, or opening the mouth may be noted, especially if the maxilla is involved.

Diagnosis

Diagnosis typically involves a thorough clinical examination and imaging studies. Common diagnostic methods include:
- X-rays: Standard radiographs can help identify fractures in the facial bones.
- CT Scans: Computed tomography provides a more detailed view of complex fractures and is often used for surgical planning.

Treatment

Management of fractures in this region depends on the type and severity of the fracture:
- Conservative Treatment: Minor fractures may be treated with pain management and observation.
