Bogart–Bacall syndrome (BBS) is a voice disorder that is caused by abuse or overuse of the vocal cords.
People who speak or sing outside their normal vocal range can develop BBS; symptoms are chiefly an unusually deep or rough voice, or dysphonia, and vocal fatigue. The people most commonly affected are those who speak in a low-pitched voice, particularly if they have poor breath and vocal control. The syndrome can affect both men and women. In 1988, an article was published describing a discrete type of vocal dysfunction which results in men sounding like actor Humphrey Bogart and women sounding like actress Lauren Bacall; Bogart and Bacall were married to each other and made several films together. BBS is now the medical term for an ongoing hoarseness that often affects actors, singers or TV/radio voice workers who routinely speak in a very low pitch. Treatment usually involves voice therapy by a speech language pathologist.
== Signs and symptoms == Signs and symptoms of Bogart–Bacall Syndrome can appear differently depending on the vocal use of the individual. In singers, symptoms may appear more subtly due to their extreme sensitivity to small changes in the laryngeal mechanism and being able to control their laryngeal muscles more than the average person. This vocal control can compensate for irritation, weakness, or change in vibration patterns for the vocal folds. Signs and symptoms will vary on a case-by-case basis and will depend on vocal strain and the degree of daily use. Women are also more susceptible than men to experience heightened symptoms due to their increased likelihood of speaking at a lower pitch in professional settings. Signs and symptoms of Bogart–Bacall include the following:
Vocal fatigue Unnaturally deep or rough voice Hoarseness Sore larynx (tightness or muscle aches in the throat) Sudden breaks or fading of the voice Loss of vocal range when singing Feeling the need to clear the throat often Experiencing loss of speech
== Cause == The cause of Bogart–Bacall syndrome is most commonly identified as abuse or overuse of the vocal cords. Individuals who speak or sing outside of their normal range can develop BBS over a long period of misuse. Individuals who develop this syndrome tend to speak or perform with poor breath support and laryngeal muscle tension. Causes include speech and communication disorders, throat conditions, and work-related conditions. Speech and communication disorders refers to issues involving language and related areas such as oral motor function. Some examples include expressive language disorder, receptive-expressive language disorder, phonologic disorder, and stuttering. Throat conditions can be any one of the following:
Vocal cord paralysis Vocal cord polyps Laryngitis Achalasia Throat cancer Hypopharyngeal cancer Larynx cancer. Work-related conditions typically affect individuals whose professions require extensive use or overuse of their vocal cords. Some examples include news and television broadcasters, radio hosts, as well as singers or actors. Teachers may also be susceptible to BBS depending on their volume and how much they talk on a regular basis.
== Mechanism == There are many plausible reasons for how Bogart–Bacall and other vocal disorders occur, but it can not be determined for certain due to the many factors that play a role in speech production. Voice production requires the coordination of many muscles and other structures in the larynx. Many factors can cause the larynx to become tensed which changes the position of larynx. This affects the cartilaginous structures within the larynx leading to abnormal phonation. Bogart–Bacall refers to an unnaturally deep voice, so when lowering their voice, individuals may continue to speak even when the air in their lungs has been almost entirely expelled. Due to the effort exerted in lowering the pitch range, the muscles involved in respiration become tensed and strained along with speech. Bogart–Bacall syndrome is considered a secondary muscle tension dysphonia disorder, meaning that there is an abnormality in the voice box that causes the overuse of muscles to help produce your voice. This abnormality can be caused by an underlying medical reason or a physical exertion. By lowering vocal pitch, the larynx compresses the vocal folds which regulate air flow and production of the sounds used in speech which can cause damage to these muscles over time. Vocal fold lesions or nodules can cause changes in the vocal fold mucosa which leads to increased tension in the larynx, ultimately causing dysphonia.
== Diagnosis == A speech-language pathology evaluation with a focus on understanding the patient's vocal use history, as well as an examination of the throat and larynx should be conducted. This evaluation potentially involves imaging to visualize the vocal cords in order to identify areas that have been heavily stressed. Imaging options can include a laryngoscope, videostroboscopy, or laryngeal electromyography. Diagnosis of Bogart–Bacall can be difficult due to the variance in symptom presentation and vocal use. Videostroboscopy provides a magnified, slow-motion view of the vocal cords and larynx in action which allows professionals to see any abnormal movement. Videostroboscopy can be used to visualize any swelling of the vocal folds, irritation, or polyps and growth. Occasionally, redness or bumps can be seen on vocal cords which is useful in making a correct diagnosis. Laryngeal electromyography is a test that measures the electrical signals from the voice box muscles (laryngeal muscles) during speaking, breathing, and swallowing. This evaluation is to check if vocal issues are related to any one of the following: partial paralysis resulting in muscle weakness, paralysis resulting in loss of muscle function, and the functionality of the motor unit of the laryngeal muscles. Laryngeal electromyography plays an important role in determining whether or not a nerve problem is the cause of a vocal disorder.
