Weak larynx muscles can indeed cause difficulty singing. The larynx, or voice box, houses the vocal cords, which vibrate to produce sound. When the vocal cords touch, they trap air from the windpipe, creating pressure and causing them to vibrate as puffs of air escape. The larynx muscles, therefore, play a crucial role in singing, and their weakness can lead to vocal issues. Muscle tension dysphonia, vocal cord paralysis, laryngitis, and other conditions can all impact the larynx muscles, causing difficulty in singing and speaking. Proper voice care, therapy, and medical treatments are essential to address these issues and restore vocal health.

What You'll Learn
Muscle tension dysphonia
MTD can manifest as primary or secondary MTD. Primary MTD occurs when the neck muscles are tense during speech or singing, but no abnormality is present in the larynx. On the other hand, secondary MTD arises from an underlying abnormality in the voice box, prompting the over-recruitment of other muscles to produce the voice. This abnormality could be nodules, polyps, or vocal fold paresis, for instance.
The symptoms of MTD include a voice that sounds rough, hoarse, gravelly, weak, breathy, strained, pressed, squeezed, tight, or tense. The voice may suddenly cut out, break off, change pitch, or fade away. Singing notes that were once easy may become challenging. Additionally, the voice may "give out" or become weaker with prolonged use.
Diagnosing MTD is intricate as it often mimics other illnesses, and there is no definitive test. A thorough evaluation by an experienced team of voice specialists and speech-language pathologists is crucial. This evaluation includes a camera examination of the vocal folds and a full history and examination to exclude other causes.
Treatment for MTD typically involves voice therapy with a speech-language pathologist, aimed at reducing throat tension and optimizing vocal efficiency. This therapy may be accompanied by other treatments like massage, acupuncture, psychotherapy, or physical therapy to facilitate tension release. In some cases, Botox injections may be used alongside voice therapy to stop voice box spasms.

Laryngitis and vocal cord nodules, polyps and cysts
Laryngitis is the swelling or inflammation of the vocal cords, which may cause a person to lose their voice or sound weak, hoarse, or raspy. Overusing the vocal cords, infections, smoking, and chronic acid reflux (GERD) are all possible causes of laryngitis.
Vocal cord nodules, polyps, and cysts are benign (noncancerous) growths that may form on one or both vocal cords. They include solid lumps or bumps (nodules and polyps) and fluid-filled growths (cysts). These growths can cause a person's voice to sound weak or hoarse, or they may lose their voice completely. Straining or misusing the vocal cords, such as through frequent yelling or speaking for extended periods, are common causes of these growths. Other factors include hypothyroidism, chronic acid reflux, excessive alcohol or caffeine consumption, and smoking.
To diagnose vocal cord disorders, a healthcare provider will take a complete medical history and perform a physical examination. They may also use a laryngoscope to examine the vocal cords internally. Treatment options depend on various factors, including the patient's age, overall health, and medical history. Resting the voice and behaviour changes are often recommended, along with voice therapy to improve vocal efficiency and prevent future injury. In some cases, surgery may be necessary to remove growths.
It is important to seek medical attention if hoarseness or other symptoms of a vocal cord disorder persist for more than two to three weeks. By consulting with healthcare professionals, individuals can receive prompt and effective treatment for conditions like laryngitis, vocal cord nodules, polyps, and cysts, preserving their vocal cord function, and improving their overall vocal health.

Vocal fatigue
Singing for long periods can strain the muscles in the throat and larynx, causing vocal fatigue. This can lead to a feeling of tightness in the throat and a perception that more effort is needed to produce sound. In some cases, vocal fatigue can be caused by underlying conditions such as laryngitis, vocal cord nodules, polyps, or cysts. It can also be caused by overuse or misuse of the vocal cords, such as talking or singing too much, whispering, or spending too much time yelling.
To prevent vocal fatigue, it is important to rest the voice and avoid speaking or singing when the voice is hoarse or weak. Staying hydrated is also crucial for vocal health. Additionally, it is important to warm up before singing and to cool down the voice afterward. Therapeutic exercises, such as blowing bubbles into a cup of water and singing on a "zz" sound, can help to stretch out any muscular tension and improve vocal fold posturing.
If vocal fatigue persists or is accompanied by pain, it is recommended to seek advice from a laryngologist or a voice therapist. Voice therapy can help individuals learn to use their vocal cords properly and reduce muscle tension in the throat and larynx. In some cases, medical or surgical treatments may be necessary to address underlying conditions.
Overall, vocal fatigue is a common condition that can be managed through proper vocal care and, if necessary, professional treatment. Singers should be mindful of their vocal health and take appropriate measures to prevent and address vocal fatigue.

Laryngeal cancer
The symptoms of laryngeal cancer include persistent hoarseness (lasting more than three weeks), a sore throat, and a persistent cough. Other possible symptoms are bad breath, unintentional weight loss, and extreme fatigue or tiredness. These symptoms can often be mistaken for less serious conditions, such as a cold or laryngitis, so it is important to seek medical advice if they persist.
The biggest risk factor for developing laryngeal cancer is smoking tobacco, with 70% to 95% of cases attributed to this habit. Other risk factors include alcohol consumption, older age (over 55 or 60), and male gender. Certain genetic syndromes, such as Fanconi anaemia and dyskeratosis congenita, are also associated with higher rates of laryngeal cancer.
The treatment options for laryngeal cancer include surgery, radiotherapy, chemotherapy, and targeted cancer medicines. Early detection significantly improves the chances of successful treatment and cure. Surgery may involve removing part or all of the larynx (laryngectomy), which can impact the patient's ability to speak and breathe in the usual way. However, there are surgical procedures that aim to preserve the patient's voice.

Laryngeal electromyography (LEMG)
LEMG is particularly useful for differentiating between disorders involving upper motor neurons, lower motor neurons, peripheral nerves, the neuromuscular junction, muscle fibres, and the laryngeal cartilages and joints. It can help diagnose vocal cord paralysis, which prevents the normal opening and closing of vocal cords, causing difficulties in speaking, breathing, and swallowing. LEMG can also predict the severity of paresis and indicate whether therapy alone or a combination of therapy and surgery is required for treatment.
Additionally, LEMG is valuable in differentiating vocal fold paresis/paralysis from cricoarytenoid joint fixation. It has been found that visual assessment alone is inadequate for diagnosing neuromuscular dysfunction in the larynx, and LEMG results show that diagnoses based solely on vocal dynamics assessment and strobovideolaryngoscopy can be incorrect in about one-third of cases.
In summary, Laryngeal electromyography (LEMG) is a valuable clinical tool for assessing neuromuscular function in the larynx and guiding treatment decisions for voice disorders, including vocal cord paralysis and vocal fold paresis/paralysis.

Frequently asked questions
Muscle tension dysphonia is a change in the sound or feel of your voice due to excessive muscle tension in and around the voice box. This tension can cause a voice to sound rough, hoarse, gravelly, weak, breathy, airy, strained, or pressed.
Muscle tension dysphonia can be caused by irritants, laryngitis, stress, vocal cord injury, excessive talking, loud talking, yelling, or speaking at a pitch that is too high or too low.
Muscle tension dysphonia can be treated with voice therapy, which helps patients learn to relax their throat muscles, use their breath more efficiently, and improve oral resonance. Other treatments include massage, acupuncture, psychotherapy, and physical therapy.
Difficulty singing can be caused by vocal cord paralysis, laryngeal cancer, laryngitis, vocal cord nodules, polyps, cysts, or vocal fatigue.
