    • 2 Pages

    Total laryngectomy, as surgical treatment for locally advanced laryngeal tumors, interferes with all functions of the larynx, i.e., phonation, respiration, and occasionally deglutition Most problems of laryngectomized patients are related to the loss of voice:Patient won’t be able to be Express themselves clearly especially inside noisy environment and that may lead them to depression and other psychological problems affecting their quality of life ,two important measures must be done To avoid such complications : rapid intervention with prosthetic valve and appropriate application of that valve according to the patient needs . 1 several silicone tracheoesophageal valve pros-theses have been developed, and promising voice rehabilitation results after total laryngectomy have been reported. These one-way valve prostheses allow sufficient shunting of expiratory air into the esopha-gus without leakage of esophageal contents into the trachea. One of the drawbacks of voice prostheses is their limited lifetime as a result of deterioration of the silicone valve, leading to leakage of esophageal contents into the trachea and a need for increased effort in order to produce fluent shunt esophageal speech. Colonization and invasion of silicone mate-rial…

    A French mathematician name Daniel Bernoulli (1700-1782) was able to identify an energy principle to determine how internal pressure and liquid or gas content react. Bernoulli’s principle educates us about how the vocal folds are used for phonation. With the myoelasticity helping the vocal folds to return to a natural resting state, the intrinsic muscles located in the larynx help the folds come together, closing off the glottis. The stream of air and gas being pushed out of the lungs puts…

    The patient struggled with this task and instead produced normal phonation rather than glottal fry. Inhalation Phonation (10:37) This speech task required the patient to produce phonation on the inhalation. This task assesses the ability of the true vocal folds without the involvement of any supraglottal activity. The patient had difficulty with this task and phonated on the exhalation rather than the inhalation. Laryngeal Massage (10:56) This speech task involved the clinician performing a…

    I will now describe the myoelastic-aerodynamic theory using the following diagram. Diagram A starts on the exhalation phase and the vocal folds are in phonatory position. The vocal folds are contracted by the Interarytenoids and the Lateral cricoid arytenoids. These muscles (IA and LCA) put the vocal folds in the phonotory position to initiate the vibratory cycle. Medial compression is the force exerted by the IA and LCA. The LCA and IA remain contracted throughout phonation when in the…

    The voice pitch is a trait that has evolved through sexual selection of humans and has become sexually dimorphic.

    The approaches I would use would be teaching the client many relaxation techniques. If anxiety and stress are major factors that affect the way Ms. Chang is using her vocal mechanism, teaching relaxation would limit tension in the vocal folds and allow for a more healthy vibration of the vocal folds. Techniques may include the yawn/sigh because “…the physiology of the yawn is incompatible with the excessive laryngeal tension that many patients exhibit. Easy, natural airflow and phonation are…

    The first three recordings were collected two weeks before the start of the treatment period.

    Also known as breathy phonation, a light voice, easy, breathy and low airflow and not a breathy whisper. This therapy is useful for post-surgery to slowly and safely lead to loudness and help mucosal repair. For this style of phonation to succeed, low-effort is of the utmost importance. It is important to clarify that the low-effort mentioned here does not mean low pitch or low tone (pharyngeal). First and foremost, the normal tone of the voice is maintained, and even a tad increase of…

    When you hear an amazing singer with a great voice, you might ask yourself what the normal life span of such a voice might be, and whether proper training or certain techniques prevent vocal cords deteriorating with age, and if surgery or some sort of special gel could correct such problems Voice experts believe that one should think of singers as athletes, using muscles in what is, after all a very physical activity. Professional singer, as well as acting as voice instructor at the Minneapolis…
