Mild cases are managed by limiting activity, keeping a healthy body weight, and avoiding exposure to high ambient temperatures. Mild sedatives can be used to decrease anxiety and panting and therefore improve respiration. Corticosteroids may also be administered in acute cases to decrease inflammation and edema of the larynx.
Severe acute symptoms, such as difficulty breathing, hyperthermia, or aspiration pneumonia, must be stabilized with sedatives and oxygen therapy and may require steroid or antibiotic medications. Sometimes a tracheotomy is required to allow delivery of oxygen. Once the patient is stabilized, surgical treatment may be beneficial especially when paralysis occurs in both aretynoid cartilages (bilateral paralysis). The surgery (aretynoid lateralization, or a "laryngeal tieback") consists of suturing one of the aretynoid cartilages in a maximally abducted (open) position. This reduces the signs associated with inadequate ventilation (such as exercise intolerance or overheating) but may exacerbate the risk of aspiration and consequent pneumonia. Tying back only one of the aretynoid cartilages instead of both helps reduce the risk of aspiration. Afterwards the dog will still sound hoarse, and will need to be managed in the same way as those with mild cases of LP.
Recent studies have found that many dogs with laryngeal paralysis have decreased motility of their esophagus. Animals with a history of regurgitation or vomiting should be fully evaluated for esophageal or other gastrointestinal disorders. Dogs with megaesophagus or other conditions causing frequent vomiting or regurgitation are at high risk for aspiration pneumonia after laryngeal tie-back. Permanent tracheostomy is an alternative surgical option for these dogs to palliate their clincical signs.
Besides complications of surgery and anesthesia in general, there may be drainage, swelling, or redness of the incision, gagging or coughing during eating or drinking, or pneumonia due to aspiration of food or liquids. Undesirable complications are estimated to occur in 10-30% of cases. If medical therapy is unsuccessful and surgery cannot be performed due to concurrent disease (such as heart or lung problems) or cost, euthanasia may be necessary if the animal's quality of life is considered unacceptable due to the disease.
Ressurance to the patient when no cause can be found.
In case of a cause treat the cause.
The risk may be reduced by administering a non-particulate antacid (e.g. Sodium Citrate) or an H-antagonist like Ranitidine.
The natural prognosis of VCD in both children and adults is not well described in the literature. Additionally, there is currently no research that has studied whether the underlying cause of VCD makes a difference in the resolution of symptoms or in the long-term prognosis of the impairment.
Information on the prognosis of VCD after acute therapies is also limited. Minimal response has been documented with the continued treatment of asthma in people with VCD using inhaled bronchodilators, corticosteroids and other asthma medications. While using Botox in VCD has limited reports, those that are available report successful resolution of exercise-induced VCD symptoms for up to 2 months.
Outcomes of chronic VCD treatment are similarly limited. When pediatric patients undergoing hypnosis therapy were studied, more than half saw either a reduction or resolution of VCD. Even though it is widely used, no long-term studies have been done to study the prognosis of VCD after psychotherapy.
Speech therapy is the main course of treatment for long-term management of VCD and includes a variety of techniques such as relaxed-throat breathing, respiratory retraining therapy, and vocal hygiene counselling. Most studies agree that symptoms of VCD improve in patients and few continue to require asthma medications six months post speech therapy intervention. Significant improvements were reported for respiratory retraining therapy, including fewer episodes of dyspnea per month and decreased respiratory stress severity.
For those adolescent patients who recovered from VCD, the average time before the symptoms were resolved was 4–5 months. However, some adolescents had VCD symptoms even 5 years post VCD onset, regardless of intervention. It has been noted that some patients do not respond to standard VCD therapies and continue to express recurrent symptoms.
Once a diagnosis of VCD has been confirmed by a medical professional, a specific treatment plan can be implemented. If vocal cord dysfunction is secondary to an underlying condition, such as asthma, gastroesophageal reflux disease (GERD), or postnasal drip, it is important to treat the primary condition as this will help control VCD symptoms.
Conventional treatments for VCD are often multidisciplinary and include speech-language pathology, psychotherapy, behavioral therapy, use of anti-anxiety and anti-depressant medications, medical interventions, and hypnotherapy. There is no uniform approach.
The information from randomized, blinded studies is limited.
There is no known treatment for FTS, as the cause is not yet known. There are conflicting reports on whether the paralysis is reversible; some sources claim that moving an elephant away from the area in which it contracted the condition will allow it to recover, while others claim that damage to the trunk is irreversible.
In some extreme cases, wildlife managers have killed affected elephants for humane reasons.
Medical and surgical treatments have been recommended to treat organic dysphonias. An effective treatment for spasmodic dysphonia (hoarseness resulting from periodic breaks in phonation due to hyperadduction of the vocal folds) is botulinum toxin injection. The toxin acts by blocking acetylcholine release at the thyro-arytenoid muscle. Although the use of botlinum toxin injections is considered relatively safe, patients' responses to treatment differ in the initial stages; some have reported experiencing swallowing problems and breathy voice quality as a side-effect to the injections. Breathiness may last for a longer period of time for males than females.
Surgeries involve myoectomies of the laryngeal muscles to reduce voice breaks, and laryngoplasties, in which laryngeal cartilage is altered to reduce tension.
Given that certain occupations are more at risk for developing dysphonia (e.g. teachers) research into prevention studies have been conducted. Research into the effectiveness of prevention strategies for dysphonia have yet to produce definitive results, however, research is still ongoing. Primarily, there are two types of vocal training recognized by professionals to help with prevention: direct and indirect. Direct prevention describes efforts to reduce conditions that may serve to increase vocal strain (such as patient education, relaxation strategies, etc.), while indirect prevention strategies refer to changes in the underlying physiological mechanism for voice production (e.g. adjustments to the manner in which vocal fold adduction occurs, respiratory training, shifting postural habits, etc.).
First-generation antihistamine has been suggested as first-line therapy to treat post-nasal drip.
Globus pharyngis (also known as globus sensation, globus or, somewhat outdatedly, globus hystericus, commonly referred to as having a "lump in one's throat"), is the persistent sensation of having phlegm, a pill or some other sort of obstruction in the throat when there is none. Swallowing can be performed normally, so it is not a true case of dysphagia, but it can become quite irritating. One may also feel mild chest pain or even severe pain with a clicking sensation when swallowing.
Historically it is said that a patient is at risk if they have:
- Residual gastric volume of greater than 25ml, with
- pH of less than 2.5
However these are indirect measurements and are not factors that directly influence aspiration risk.
Patients with a high risk should have a rapid sequence induction. High risk is defined as these factors:
1. Non-elective surgical procedure
2. Light anaesthesia/unexpected response to stimulation
3. Acute or chronic, upper or lower GI pathology
4. Obesity
5. Opioid medication
6. Neurological disease, impaired conscious level, or sedation
7. Lithotomy position
8. Difficult intubation/airway
9. Gastrointestinal reflux
10. Hiatal hernia
Some elements of cholinergic crisis can be treated with antimuscarinic drugs like atropine, but the most important element, respiratory arrest, cannot. The neuromuscular junction, where the brain communicates with muscles (like the diaphragm, the main breathing muscle), works by acetylcholine activating nicotinic acetylcholine receptors and leading to muscle contraction. Atropine blocks muscarinic acetylcholine receptors (a different subtype than the nicotinic receptors at the neuromuscular junction), so atropine will not improve the muscle strength and ability to breathe in someone with cholinergic crisis. Such a patient will require mechanical ventilation support via endotracheal intubation until the crisis resolves on its own. The respiratory compromise from cholinergic crisis unfortunately has no pharmacologic solution or therapy.
There are a number of potential treatments for spasmodic dysphonia, including botox, surgery and voice therapy. A number of medications have also been tried including anticholinergics (such as benztropine) which have been found to be effective in 40-50% of people, but which are associated with a number of side effects.
Physiotherapy
To increase strength of muscle
To improve muscle functions
Electrical modalities =Electric stimulation.etc.

The disease has only been identified as distinct from SMA recently, so research is still experimental, taking place mostly in animal models. Several therapy pathways have been devised which include gene therapy, whereby an "IGHMBP2" transgene is delivered to the cell using a viral vector; small-molecule drugs like growth factors (e.g., IGF-1 and VEGF) or olesoxime; and transplantation of healthy motor neurons grown "in vitro" from the patient's stem cells. Studies in amyotrophic lateral sclerosis are also considered helpful because the condition is relatively similar to SMARD1.
Voice therapy appears to be ineffective in cases of true spasmodic dysphonia, however as it is difficult to distinguish between spasmodic dysphonia and functional dysphonias and misdiagnosis is relatively common, a trial of voice therapy is often recommended before more invasive procedures are tried. Some also state that it is useful for mild symptoms and as an add-on to botox therapy and others report success in more severe cases. Laryngeal manual therapy, which is massaging of the neck and cervical structures, also shows positive results for intervention of functional dysphonia.
There is no known cure to DSMA1, and care is primarily supportive. Patients require respiratory support which may include non-invasive ventilation or tracheal intubation. The child may also undergo additional immunisations and offered antibiotics to prevent respiratory infections. Maintaining a healthy weight is also important. Patients are at risk of undernutrition and weight loss because of the increased energy spent for breathing. Physical and occupational therapy for the child can be very effective in maintaining muscle strength.
There is no published practice standard for the care in DSMA1, even though the Spinal Muscular Atrophy Standard of Care Committee has been trying to come to a consensus on the care standards for DSMA1 patients. The discrepancies in the practitioners’ knowledge, family resources, and differences in patient’s culture and/or residency have played a part in the outcome of the patient.
The causes of vocal process granulomas are quite varied, and as such prevention must target the individual causes. Education on lifestyle factors such as habitual vocal abuse and habits that may aggravate gastro-esophageal reflux should be implemented to lower risk, and those who use their voice professionally should use vocal hygiene techniques to ensure safe voice use. Vocal hygiene may include increasing water intake, eliminating external irritants such as smoking or airborne chemicals, controlling loudness, and balancing periods of increased vocal use with periods of rest. Since intubation can also cause vocal process granulomas, proper muscle relaxing medications should be used before insertion and removal of tubes, that smaller tubes are used and with proper lubrication, and that patient movement is controlled during intubation.
Brown-Séquard syndrome is rare as the trauma would have to be something that damaged the nerve fibres on just one half of the spinal cord.
Klumpke Palsy is listed as a 'rare disease' by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Klumpke palsy, or a subtype of Klumpke palsy, affects fewer than 200,000 people in the US population.
Management of symptoms for patients within this subgroup of the GERD spectrum is difficult. Once these patients are identified, behavioural and dietary changes are advised. Dietary modifications may include limiting the intake of chocolate, caffeine, acidic food and liquids, gaseous beverages and foods high in fat. Behavioral changes may include weight loss, cessation of smoking, limiting alcohol consumption and avoiding the ingestion of food shortly before bed. Lifestyle changes in children diagnosed with LPR include dietary modifications to avoid foods that will aggravate reflux (e.g., chocolate or acidic and spicy food), altering positioning (e.g., sleeping on your side), modifying the textures of foods (e.g., thickening feeds to heighten awareness of the passing bolus), and eliminating the intake of food before bed.
Proton pump inhibitors (PPIs) are the leading pharmaceutical intervention chosen for the relief and reduction of LPR and are typically recommended for ongoing use twice a day for a period of 3–6 months. PPIs have been shown to be ineffective in very young children and are of uncertain efficacy in older children, for whom their use has been discouraged. While PPIs may provide limited clinical benefits in some adults, there is insufficient evidence to support routine use. Many studies show that PPIs are not more effective than placebos in treating LPR.
When medical management fails, Nissen fundoplication can be offered. However, patients should be advised that surgery may not result in complete elimination of LPR symptoms and even with immediate success, recurrence of symptoms later on is still possible.
One way to assess treatment outcomes for LPR is through the use of voice quality measures. Both subjective and objective measures of voice quality can be used to assess treatment outcomes. Subjective measures include scales such as the Grade, Roughness, Breathiness, Asthenia, Strain Scale (GRBAS); the Reflux Symptom Index; the Voice Handicap Index (VHI); and a voice symptom scale. Objective measures often rely on acoustic parameters such as jitter, shimmer, signal-to-noise ratio, and fundamental frequency, among others. Aerodynamic measures such as vital capacity and maximum phonation time (MPT) have also been used as an objective measure. However, there is not yet a consensus on how best to use the measures or which measures are best to assess treatment outcomes for LPR.
Voice disorders are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include:
- Puberphonia
- Chorditis
- Vocal fold nodules
- Vocal fold cysts
- Vocal cord paresis
- Reinke's edema
- Spasmodic dysphonia
- Foreign accent syndrome
- Bogart–Bacall syndrome
- Laryngeal papillomatosis
- Laryngitis
A cholinergic crisis is an over-stimulation at a neuromuscular junction due to an excess of acetylcholine (ACh), as of a result of the inactivity (perhaps even inhibition) of the AChE enzyme, which normally breaks down acetylcholine. This is a consequence of some types of nerve gas, (e.g. sarin gas). In medicine, this is seen in patients with myasthenia gravis who take too high a dose of their cholinesterase inhibitor medications, or seen following general anaesthesia, when too high a dose of a cholinesterase inhibitor drug is given to reverse surgical muscle paralysis.
Treatment is directed at the pathology causing the paralysis. If it is because of trauma such as a gunshot or knife wound, there may be other life-threatening conditions such as bleeding or major organ damage which should be dealt with on an emergent basis. If the syndrome is caused by a spinal fracture, this should be identified and treated appropriately. Although steroids may be used to decrease cord swelling and inflammation, the usual therapy for spinal cord injury is expectant.
