What Are The Common Causes of Facial Paralysis

Facial paralysis is a condition that results in the inability to move the muscles on one or both sides of the face. This can be a temporary or permanent condition, depending on the underlying cause. It is a distressing ailment that can significantly affect a person’s quality of life, impacting their emotional expression and physical functions like eating and speaking. Dr. Gregory Lekovic has extensive experience in diagnosing and treating various causes of facial paralysis. Here, we explore some of the common etiologies of this condition.

Facial Nerve Schwannoma

Facial nerve schwannomas are benign tumors that arise from the Schwann cells surrounding the facial nerve. The facial nerve, also known as the seventh cranial nerve, is responsible for controlling the muscles of facial expression. When a schwannoma develops, it can compress the facial nerve, leading to gradual weakness or paralysis of the facial muscles. Surgical intervention by a skilled neurosurgeon like Dr. Lekovic may be necessary to remove the tumor and alleviate the pressure on the facial nerve.


A stroke occurs when the blood supply to part of the brain is interrupted, causing brain cells to die. This can result from a blocked artery or leaking or bursting of a blood vessel. When a stroke affects the areas of the brain that control the facial muscles, it can lead to facial paralysis. The paralysis affects the lower half of one side of the face and may be accompanied by other symptoms like weakness in the limbs and difficulty speaking.

Bell’s Palsy

Bell’s palsy is a condition that causes sudden, temporary weakness or paralysis of the facial muscles. It is believed to be caused by inflammation or viral infection of the facial nerve. Patients with Bell’s palsy often experience a rapid onset of mild weakness to total paralysis on one side of their face. While the exact cause is unknown, it is often associated with viral infections like herpes simplex. Most patients recover fully with or without treatment, but some may experience lasting effects.

Skull Fracture

Facial paralysis can also result from a skull fracture, where a break in one of the skull bones causes damage to the facial nerve. This type of paralysis is often immediate and can be associated with other symptoms like bleeding from the ear or bruising around the eyes. The treatment of a skull fracture depends on the severity and may involve surgical intervention to repair the fracture and relieve pressure on the facial nerve.

Head, Neck, or Brain Tumor

Tumors in the head, neck, or brain can lead to facial paralysis by directly compressing the facial nerve or by invading the nerve itself. These tumors may be benign or malignant and require a thorough evaluation for proper diagnosis and treatment. Dr. Lekovic’s expertise in neurosurgery is particularly valuable in these cases, where precise surgical techniques are needed to remove the tumor while preserving facial nerve function.

Middle Ear Infection

Middle ear infections, or otitis media, can cause facial paralysis when the infection spreads to the facial nerve. This is more common in severe infections and can result in sudden facial weakness. Treatment typically involves antibiotics and sometimes drainage of the fluid from the middle ear. In some cases, further evaluation and treatment may be necessary.

Other Possible Causes:

  • Lyme disease
  • Sarcoidosis
  • Autoimmune disorders
  • Diabetes mellitus
  • Myasthenia gravis
  • Guillain-Barré syndrome
  • Syphilis
  • Ear surgery complications
  • Temporal bone fracture
  • Congenital facial palsy
  • Neurosarcoidosis
  • Multiple sclerosis

Facial paralysis is a condition with a wide range of potential causes. Each case requires a personalized approach to diagnosis and treatment. Dr. Lekovic’s experience in neurosurgery provides patients with the expertise necessary to address the various underlying causes of facial paralysis.
