Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
However, the stapedial muscle is innervated by the facial nerve while the tensor tympani is innervated by the trigeminal nerve. The tensor tympani pulls the manubrium of the malleus inwards and tightens it while the stapedial muscle pulls the stapes inward. This tightening damps the sound vibration that is allowed to penetrate the cochlea.
Bell's palsy is a type of facial paralysis that results in a temporary inability to control the facial muscles on the affected side of the face. [1] In most cases, the weakness is temporary and significantly improves over weeks. [4] Symptoms can vary from mild to severe. [1]
Tonic tensor tympani syndrome is a disease of the tensor tympani muscle, described by Klochoff et al. in 1971. [1] [2] The tensor tympani muscle is one of the two middle ear muscles that support the three middle ear bones, called the ossicles. TTTS involves tensor tympani muscle activity being reduced, leading to a decrease in the contraction ...
Although a temporary solution, surgical ventilation tube placement in the ear drum has also proven to be an effective treatment option. This treatment is known as either a unilateral or bilateral myringotomy . 50% of patients reported relief of patulous Eustachian tube symptoms when given this treatment.
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
Alternative treatment methods include muscle transfer techniques, such as the gracilis free muscle transfer [16] or static procedures. Patients with facial nerve paralysis resulting from tumours usually present with a progressive, twitching paralysis, other neurological signs, or a recurrent Bell's palsy-type presentation.
