    Hemifacial spasm (HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions on one side (hemi-) of the face (-facial). [1] The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches.

    Paresthesia, also known as pins and needles, is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause. [1] Paresthesia may be transient or chronic, and may have many possible underlying causes. [ 1 ]

  4. Facial nerve paralysis - Wikipedia

    en.wikipedia.org/wiki/Facial_nerve_paralysis

    Facial palsy is considered severe if the person is unable to close the affected eye completely or the face is asymmetric even at rest. Corticosteroids initiated within three days of Bell's palsy onset have been found to increase chances of recovery, reduce time to recovery, and reduce residual symptoms in case of incomplete recovery.

    Inferior alveolar nerve block (abbreviated to IANB, and also termed inferior alveolar nerve anesthesia or inferior dental block) is a nerve block technique which induces anesthesia (numbness) in the areas of the mouth and face innervated by one of the inferior alveolar nerves which are paired on the left and right side.

  6. Nerve compression syndrome - Wikipedia

    en.wikipedia.org/wiki/Nerve_compression_syndrome

    These paresthesias may be painful, such as shooting pain, burning, or a dull ache. They may also be pain-free, such as numbness or tingling. Motor nerve entrapment may present with muscle weakness or paralysis for voluntary movements of the innervated muscles. Entrapment of certain pelvic nerves can cause incontinence and/or sexual dysfunction. [2]

  7. Facial trauma - Wikipedia

    en.wikipedia.org/wiki/Facial_trauma

    Deformity in the face, for example a sunken cheekbone or teeth which do not align properly, suggests the presence of fractures. Asymmetry can suggest facial fractures or damage to nerves. [3] People with mandibular fractures often have pain and difficulty opening their mouths and may have numbness in the lip and chin. [4]

  8. Dysesthesia - Wikipedia
