== Prevention and treatment == Prevention of Bogart–Bacall syndrome aims to target the two main symptoms of this disorder, dysphonia and vocal fatigue. Having effective posture allows a person to shift the tension between the muscles allowing free movement of the larynx without blockage leading to effective voice production. Improvement of breath control with a professional vocal coach is also important for individuals who may have work-related conditions that require continuous strain on the vocal cords and larynx. Speech therapy with a speech-language pathologist is a very common method of treatment to return speaking level to its normal pitch range. Consultation with a speech-language pathologist will determine what levels of rest, fluid, and performance corrections are needed for the vocal cords and larynx to sustain a healthy voice. If there is a particular underlying cause of the condition that can be treated with medication, this can be coupled with speech therapy as a form of treatment. Individuals with persistent symptoms after speech therapy may require more invasive treatment. Invasive treatment may require the removal of lesions, nodules, or masses on the vocal cords if visualized during diagnostic imaging. If the disorder is found to be nerve related through electromyography the nerve in question may need to be replaced or the vocal cords can be pushed together with a bulk injection or thyroplasty. A bulk injection involves adding a filler substance to the paralyzed vocal cord to have it vibrate closer to the functioning vocal cord. Thyroplasty involves the insertion of an implant against the paralyzed vocal cord moving it closer to the other vocal cord.
== Prognosis == Individuals with Bogart–Bacall syndrome that do not have an underlying condition are typically expected to make a vocal recovery through voice therapy. Having a form of muscle tension dysphonia go untreated, can cause further long-term disorders that require additional forms of treatment.
== Epidemiology == Bogart–Bacall syndrome can develop in individuals at any age. It is more likely to develop in individuals who work in voice performance which can range from singers, actors, teachers or radio and television broadcasters. Women are more likely than men to develop BBS due to the tendency of lowering their voices in a professional environment. This syndrome is also more prevalent in the 40–50-year-old-age group as their vocal cords thin. Vocal disorders are prevalent in roughly 10% of the population and can range from muscle tension dysphonia to speech and language disorders.
== Research directions == Further studies need to be conducted to further examine the long-term effects of Bogart–Bacall syndrome if left untreated. Studies that are currently ongoing aim to understand what the best course of treatment may be for individuals with muscle tension dysphonia, which includes individuals with Bogart–Bacall. It is currently understood that an interdisciplinary approach to target the causes such as poor breath support, overuse, and inappropriate intensity is most effective. Vocal disorders and misuse are currently being researched depending on work conditions and professions. A study based on over 1,200 teachers has indicated that voice disorders play a significant role in their profession. The study found that a substantial number of teachers have needed to take time off work or seek medical attention due to voice issues or to seek treatment. The study also found that women are more likely to develop these disorders over their male counterparts. There is more research available on vocal disorders and how they may be affected by additional lifestyle factors. A study was conducted to understand how reflux affected vocal disorders such as dysphonia in singers with bulimia. Singers tend to overuse their vocal cords which makes them very susceptible to a variety of vocal disorders. Dysphonia associated with bulimia has been linked to vocal fold edema and polypoid changes. The aim was to understand if bulimia was linked to laryngopharyngeal reflux as a plausible cause of dysphonia. In preliminary results, it was understood that reflux was the case in every singer with bulimia and dysphonia, indicating it may be a contributing factor to their vocal disorder.
