Spasmodic torticollis

Torticollis, or wry neck, is a condition in which the head is tilted toward one side, and the chin is elevated and turned toward the opposite side. Torticollis can be congenital or acquired. The etiology of congenital torticollis is unclear, but it is thought that birth trauma causes damage to the sternocleidomastoid muscle in the neck, which heals at a shorter length and causes the characteristic head position. Sometimes a mass in the muscle may be noted, but this mass may disappear within a few weeks of birth. more...

If the condition is detected early in life (before one year of age) it is treated with physical therapy and stretching to correct the tightness. The use of a TOT Collar can also be very effective. This treatment is usually all that is necessary to fix the problem. Particularly difficult cases may require surgical lengthening of the muscle if stretching fails. Also, if the condition does not respond well to stretching, other causes such as tumors, infections, ophthalmologic problems and other abnormalities should be ruled out with further testing. If torticollis is not corrected before one year of age, facial asymmetry can develop and is impossible to correct.

Acquired torticollis occurs because of another problem and usually presents in previously normal children. Trauma to the neck can cause atlantoaxial rotatory subluxation, in which the two vertebrae closest to the skull slide with respect to each other, tearing stabilizing ligaments; this condition is treated with traction to reduce the subluxation, followed by bracing or casting until the ligamentous injury heals. Tumors of the skull base (posterior fossa tumors) can compress the nerve supply to the neck and cause torticollis, and these problems must be treated surgically. Infections in the posterior pharynx can irritate the nerves supplying the neck muscles and cause torticollis, and these infections may be treated with antibiotics if they are not too severe, but could require surgical debridement in intractable cases. Ear infections and surgical removal of the adenoids can cause an entity known as Grisel's syndrome, in which a bony bridge develops in the neck and causes torticollis. This bridge must either be broken through manipulation of the neck, or surgically resected. There are many other rare causes of torticollis.

Evaluation of a child with torticollis begins with history taking to determine circumstances surrounding birth, and any possibility of trauma or associated symptoms. Physical examination reveals decreased rotation and bending to the side opposite from the affected muscle; 75% of congenital cases involve the right side. Evaluation should include a thorough neurologic examination, and the possibility of associated conditions such as developmental dysplasia of the hip and clubfoot should be examined. Radiographs of the cervical spine should be obtained to rule out obvious bony abnormality, and MRI should be considered if there is concern about structural problems or other conditions. Evaluation by an ophthalmologist should be considered in older children to ensure that the torticollis is not caused by vision problems. Most cases in infants respond well to physical therapy. Other causes should be treated as noted above.

Spasmodic Dysphonia - Pamphlet
From Pamphlet by: National Institute on Deafness and Other Communication Disorders, 1/1/00

What is spasmodic dysphonia?

Spasmodic dysphonia (or laryngeal dystonia) is a voice disorder caused by involuntary movements of one or more muscles of the larynx or voice box. Individuals who have spasmodic dysphonia may have occasional difficulty saying a word or two or they may experience sufficient difficulty to interfere with communication. Spasmodic dysphonia causes the voice to break or to have a tight, strained or strangled quality. There are three different types of spasmodic dysphonia.

What are the types of spasmodic dysphonia?

The three types of spasmodic dysphonia are adductor spasmodic dysphonia, abductor spasmodic dysphonia and mixed spasmodic dysphonia.

What are the features of spasmodic dysphonia? [up arrow]

In adductor spasmodic dysphonia, sudden involuntary muscle movements or spasms cause the vocal folds (or vocal cords) to slam together and stiffen. These spasms make it difficult for the vocal folds to vibrate and produce voice. Words are often cut off or difficult to start because of the muscle spasms. Therefore, speech may be choppy and sound similar to stuttering. The voice of an individual with adductor spasmodic dysphonia is commonly described as strained or strangled and full of effort. Surprisingly, the spasms are usually absent while whispering, laughing, singing, speaking at a high pitch or speaking while breathing in. Stress, however, often makes the muscle spasms more severe.

In abductor spasmodic dysphonia, sudden involuntary muscle movements or spasms cause the vocal folds to open. The vocal folds can not vibrate when they are open. The open position of the vocal folds also allows air to escape from the lungs during speech. As a result, the voices of these individuals often sound weak, quiet and breathy or whispery. As with adductor spasmodic dysphonia, the spasms are often absent during activities such as laughing or singing.

Mixed spasmodic dysphonia involves muscles that open the vocal folds as well as muscles that close the vocal folds and therefore has features of both adductor and abductor spasmodic dysphonia.

Who is affected by spasmodic dysphonia?

Spasmodic dysphonia can affect anyone. The first signs of this disorder are found most often in individuals between 30 and 50 years of age. More women appear to be affected by spasmodic dysphonia than are men.

What causes spasmodic dysphonia? [arrow up]

The cause of spasmodic dysphonia is unknown. Because the voice can sound normal or near normal at times, spasmodic dysphonia was once thought to be psychogenic, that is, originating in the affected person(1)s mind rather than from a physical cause. While psychogenic forms of spasmodic dysphonia exist, research has revealed increasing evidence that most cases of spasmodic dysphonia are in fact neurogenic or having to do with the nervous system (brain and nerves). Spasmodic dysphonia may co-occur with other movement disorders such as blepharospasm (excessive eye blinking and involuntary forced eye closure), tardive dyskinesia (involuntary and repetitious movement of muscles of the face, body, arms and legs), oromandibular dystonia (involuntary movements of the jaw muscles, lips and tongue), torticollis (involuntary movements of the neck muscles), or tremor (rhythmic, quivering muscle movements).

In some cases, spasmodic dysphonia may run in families and is thought to be inherited. Research has identified a possible gene on chromosome 9 that may contribute to the spasmodic dysphonia that is common to certain families. In some individuals the voice symptoms begin following an upper respiratory infection, injury to the larynx, a long period of voice use, or stress.

How is spasmodic dysphonia diagnosed?

The diagnosis of spasmodic dysphonia is usually made based on identifying the way the symptoms developed as well as by careful examination of the individual. Most people are evaluated by a team that usually includes an otolaryngologist (a physician who specializes in ear, nose and throat disorders), a speech-language pathologist (a professional trained to diagnose and treat speech, language and voice disorders) and a neurologist (a physician who specializes in nervous system disorders). The otolaryngologist examines the vocal folds to look for other possible causes for the voice disorder. Fiberoptic nasolaryngoscopy, a method whereby a small lighted tube is passed through the nose and into the throat, is a helpful tool that allows the otolaryngologist to evaluate vocal cord movement during speech. The speech-language pathologist evaluates the patient's voice and voice quality. The neurologist evaluates the patient for signs of other muscle movement disorders.

What treatment is available for spasmodic dysphonia? [arrow up]

There is presently no cure for spasmodic dysphonia. Current treatments only help reduce the symptoms of this voice disorder. Voice therapy may reduce some symptoms, especially in mild cases. An operation that cuts one of the nerves of the vocal folds (the recurrent laryngeal nerve) has improved the voice of many for several months to several years but the improvement is often temporary. Others may benefit from psychological counseling to help them to accept and live with their voice problem. Still others may benefit from job counseling that will help them select a line of work more compatible with their speaking limitations.

Currently the most promising treatment for reducing the symptoms of spasmodic dysphonia is injections of very small amounts of botulinum toxin (botox) directly into the affected muscles of the larynx. Botulinum toxin is produced by the Clostridium botulinum bacteria. This is the bacterium that occurs in improperly canned foods and honey. The toxin weakens muscles by blocking the nerve impulse to the muscle. The botox injections generally improve the voice for a period of three to four months after which the voice symptoms gradually return. Reinjections are necessary to maintain a good speaking voice. Initial side effects that usually subside after a few days to a few weeks may include a temporary weak, breathy voice or occasional swallowing difficulties. Botox may relieve the symptoms of both adductor and abductor spasmodic dysphonia.
