The mechanism of the vocal quality variation is impacted by the quality of the: The mechanism of the vocal quality variation is impacted by the quality of the phonatory system (tissues)
What does smoking fo to your vocal folds?: Smoking irritates the vocal cords and dries the vocal cord mucosa. It also results in inflammation on the vocal cords. This in turn can cause coughing, sputum, and vocal cord feelings of irritation.
Sputum: A mixture of saliva and mucus coughed up from the respiratory tract, typically s a result of infection or other disease and often examined microscopically to aid medical diagnosis.
The coordination of ___ influences the mechanism of vocal quality variation: muscles (tremor)
What is a disease in which the voice sounds tremorous or shaky?: Spasmodic dysphonia is a disease in which the voice sounds tremorous or shaky because it affects the vocal cords. Parkinson’s disease is also characterized by tremor and muscle weakness/slowness. Patients with Parkinsons notice that their voice becomes weak and tremulous
The shape and configuration of the ___ can affect the mechanism of vocal quality variation: The shape and configuration of the vocal tract (cleft palate) can affect the mechanism of vocal quality variation
The size of ___ can affect the mechanism of vocal quality variation: The size of resonators (oral, nasal, pharyngeal) can affect the mechanism of vocal quality variation
The three types of resonators are: oral, nasal, and pharyngeal
What is the edge of the vibrating tissue called?: The edge of the vibrating tissue is the periodicity

Voice pathologists should be aware of the differences between: The differences between the adult and pediatric laryngeal anatomy and physiology is something voice pathologists should be aware of.
The differences between adult laryngeal anatomy and pediatric laryngeal anatomy are more significant than: The differences between adult laryngeal anatomy and pediatric laryngeal anatomy are more significant than mere size of the structures
\
In the pediatric larynx, the thyroid notch is: The thyroid notch is not as prominent in the pediatric larynx as it is in the adult larynx. It is obscured by the overlapping hyoid bone.
The thyroid cartilage of the pediatric larynx is: In the pediatric larynx, the thyroid cartilage is not as prominent as it is in the adult. However, it is more rounded with no midline vertical ridge.
In addition to the thyroid cartilage of the pediatric larynx, what else is also not prominent?: The cricoid cartilage of the pediatric larynx is also not prominent
This can be felt as a depression between the thyroid and the cricoid in the adult larynx; however, in the pediatric larynx it is just a little slit: In the adult larynx, the cricothyroid membrane can be felt as a depression between the thyroid and the cricoid; however, in the pediatric larynx it is just a little slit
\
What are the three main differences between an immature and mature larynx?: An immature larynx’s hyoid cartilage overlaps the thyroid, there is no vertical prominence in the thyroid and the cricothyroid membrane is a slit
\
What is the diameter of the pediatric trachea?: The pediatric trachea is 4-5mm in diameter
What are the aryepiglottic folds and cartilages large compared to?: The aryepiglottic folds and the arytenoid cartilages are large relative to other laryngeal structures.
How many infant epiglottis are omega shaped?: It is estimated that 50% of infant epiglottis are omega shaped.
What shape does the airway in an adult take and where does it start?: In an adult, starting from the base of the tongue, the airway takes a rather straight vertical shape.
What shape does the larynx take in a child?: In a child, the larynx takes a curved shape.
What distinguishes a child’s larynx from an adult’s larynx?: A child’s larynx contains a furled epiglottis and large arytenoids making it different from an adult’s larynx
The arytenoid cartilages are large relative to other laryngeal structures in the: pediatric larynx
In an adult, the angel of the epiglottis is: In an adult, the angel of the epiglottis is somewhat vertical and in alignment with the trachea, which is not the case in the pediatric larynx.
\
Why may normal respiratory pressure be enough to deform the laryngeal structure (e.g Laryngomalacia and Tracheomalacia)?: Because of the pliable tissue lining the pediatric larynx, normal respiratory pressure may be enough to deform laryngeal structure (e.g. Laryngomalacia and Tracheomalacia)
What aspect of the pediatric airway should be considered while conducting laryngoscopy, stroboscope and intubation?: the curved shape of the pediatric airway should be considered while conducting laryngoscopy, stroboscope and intubation
What should be taken into consideration while considering a cricothyroctomy or a cricothyroid puncture?: The narrowness of the cricothyroid membrane depression in the pediatric larynx should be taken into consideration while considering a cricothyroctomy or a cricothyroid puncture. It is also important if a botox injection is considered.
\
How is surgery (otolaryngologist) used to treat the larynx?: Surgery is used to remove mass lesions (i.e. polyps, cysts). There are also injections to increase vocal fold mass (gel foam, fat), thyroplasty and arytenoid surgeries.
How is pharmacology (otolaryngologist) used to treat the larynx?: Pharmocology can be used to treat the larynx and two examples of these are steroids (used to treat edema) and BOTOX (used to treat spasmodic dysphonia)
What are six ways that the pathology of the larynx can be treated with voice therapy?: The pathology of the larynx can be treated with voice therapy from a speech language pathologist. Some techniques that can be used involves vocal hygiene counseling, eliminating vocally abusive patterns, building strength of the laryngeal muscles, increasing the resonance of the voice, laryngeal massage, and exploring the emotional/social aspects of the problem.
Carcinoma: lump in the neck, tenderness in neck, hoarseness, dysphagia, dyspnea, biopsy required for DX
Carcinoma incidence: 2-5% of all malignancies
Carcinoma induces persistent: hoarseness
Causes of carcinoma: smoking, environmental irritation, chemicals, metabolic disturbances, unknown
50-70% of laryngeal cancers are associated with: smoking
Carcinoma has a synergistic effect with: alcohol

The upper portion of the teaches (windpipe) is brought out to the: front of the neck to create a permanent opening called a stoma
When a laryngectomy patient inhales, air passes directly through: the stoma into the trachea and then into the lungs
The connection between the mouth and the esophagus is: usually not affected, so food and liquid can be swallowed just as they were before the operation
