masseterhypertrofi

Masseter hypertrophy refers to the enlargement of the masseter muscles, which are located in the jaw and are responsible for chewing. This condition can be caused by several factors, including habitual teeth grinding (bruxism), clenching the jaw, chewing excessively hard foods, or genetic predisposition. It can also be exacerbated by stress and anxiety.

The visible symptom of masseter hypertrophy is often a widening or squaring of the lower face, particularly when the jaw is clenched. Other potential symptoms may include jaw pain, headaches, difficulty opening the mouth wide, and tooth wear. In some cases, the enlarged muscles can lead to temporomandibular joint (TMJ) disorders.

Diagnosis is typically made through a physical examination by a healthcare professional, such as a dentist or physician, who will assess the size and tone of the masseter muscles and inquire about symptoms and habits. Imaging studies like ultrasound or CT scans may be used to confirm the diagnosis and rule out other conditions.

Treatment approaches vary depending on the severity and underlying cause. Behavioral modifications, such as stress management techniques and avoiding jaw-clenching habits, are often recommended. For bruxism, a dentist may prescribe a night guard to protect the teeth and reduce muscle strain. In more severe cases, medical interventions may be considered, including Botox injections, which temporarily relax the masseter muscles and reduce their size. Surgical options, such as masseter muscle reduction, are also available but are less common.
