What muscles do the facial nerve innervate?
The facial nerve passes through the stylomastoid foramen in the skull and terminates into the zygomatic, buccal, mandibular, and cervical branches. These nerves serve the muscles of facial expression, which include the frontalis, orbicularis oculi, orbicularis oris, buccinator, and platysma muscles.
Is tensor tympani control rare?
Voluntary control over the tensor tympani muscle is an extremely rare event. However, an understanding of the potential audiometric effects of its contraction could aid the diagnosis of hearing disorders.
What are the 3 ear muscles?
The auricular muscles (or extrinsic muscles) are the three muscles surrounding the auricula or outer ear:

What muscles may be affected by Bell’s palsy?
The nerve that controls your facial muscles passes through a narrow corridor of bone on its way to your face. In Bell’s palsy, that nerve becomes inflamed and swollen — usually related to a viral infection. Besides facial muscles, the nerve affects tears, saliva, taste and a small bone in the middle of your ear.
Can everyone control their tensor tympani?

What is the ear tragus?
Tragus: A posterior, slightly inferior, protrusion of skin-covered cartilage, anterior to the auditory meatus. The inferoposterior margin of the tragus forms the anterior wall of the incisura.

Outer ear pain can most commonly be caused by environmental conditions such as water exposure or extreme cold weather that can lead to frostbite of the outer ear. Other causes for ear tragus pain include irritation from obtrusive objects like cotton swabs or fingers.
How do you get rid of tonic tensor tympani syndrome?
Treatment for TTTS often involves the use of sound therapy to treat the underlining tinnitus or hyperacusis. Sound therapy uses various sounds and noises to help a person cope with the constant ringing or loud noises associated with tinnitus and hyperacusis.
What are the symptoms of hyperacusis?
Symptoms of hyperacusis
- very quiet sounds are comfortable, but ordinary sounds (like voices at conversational volume) are too loud or distorted.
- your own voice seems too loud or distorted.
- low intensity sounds, such as the noise of a refrigerator, seem too loud.
