Phoniatrics and Voice Disorders Practice Questions

Q: Blomsingher prosthesis is used for the production of?

Voice. **Explanation:** The **Blom-Singer prosthesis** is a specialized indwelling silicone valve used for **Tracheoesophageal (TE) Speech** following a total laryngectomy. **Why Voice is Correct:** When a patient undergoes a total laryngectomy, the natural "voice box" is removed. To restore communication, a surgical puncture is created between the trachea and the esophagus (Tracheoesophageal Puncture). The Blom-Singer prosthesis is a **one-way valve** inserted into this puncture. When the patient occludes their stoma and exhales, air is diverted from the lungs through the prosthesis into the esophagus. This air causes the pharyngoesophageal segment (neoglottis) to vibrate, producing a sound that is then articulated into speech. **Why Other Options are Incorrect:** * **Image:** Prosthetic devices for imaging (like contrast markers) are unrelated to the Blom-Singer valve, which is a functional speech rehabilitation tool. * **Radiowaves/Light:** These relate to diagnostic or therapeutic modalities (like Radiofrequency ablation or Laser surgery) and have no functional connection to tracheoesophageal voice prostheses. **High-Yield Clinical Pearls for NEET-PG:** * **Gold Standard:** Tracheoesophageal speech (using prostheses like Blom-Singer or Provox) is currently considered the gold standard for post-laryngectomy voice rehabilitation. * **Mechanism:** It is a one-way valve that allows air to enter the esophagus but prevents food/liquid from entering the trachea (aspiration). * **Other Methods of Speech:** Include **Esophageal Speech** (burping air) and the **Electrolarynx** (an external battery-operated vibrator). * **Complication:** The most common reason for prosthesis failure is **fungal (Candida) colonization**, which leads to valve leakage.

Q: A 35-year-old male singer presents with complaints of hoarseness, vocal fatigue, and pain in the neck on prolonged phonation. Direct laryngoscopy shows bilateral pinhead-sized swellings on the anterior one-third and posterior two-thirds junction of the vocal cords. What is the probable diagnosis?

Vocal nodule. ### Explanation **1. Why Vocal Nodule is Correct:** Vocal nodules (Singer’s nodules) are the most common cause of persistent hoarseness in individuals who use their voices professionally. The clinical hallmark is **bilateral, symmetrical, pinhead-sized swellings** located at the **junction of the anterior 1/3 and posterior 2/3** of the vocal cords. This specific site corresponds to the point of maximum vibratory amplitude and mechanical trauma. Chronic vocal abuse leads to edema and fibrosis of the Reinke’s space, manifesting as these nodules. Symptoms typically include hoarseness, vocal fatigue, and "odynophonia" (pain on phonation). **2. Why Other Options are Incorrect:** * **Vocal Polyp:** These are usually **unilateral** and larger than nodules. They often follow a single episode of vocal trauma (e.g., shouting) causing a submucosal hemorrhage. * **Acute Laryngitis:** This presents with sudden onset hoarseness, fever, and cough, usually following a viral upper respiratory infection. Laryngoscopy would show diffuse erythema and edema of the cords, not localized nodules. * **Acute Pharyngitis:** This involves inflammation of the pharynx, presenting with sore throat and dysphagia rather than primary hoarseness or localized vocal cord pathology. **3. Clinical Pearls for NEET-PG:** * **Management:** The first line of treatment is **conservative (Voice Therapy)**. Surgery (Microlaryngeal surgery) is reserved only for large or recalcitrant nodules. * **Histopathology:** Nodules represent epithelial thickening and hyalinization of the stroma. * **Demographics:** Commonly seen in teachers, singers, and energetic male children ("Screamer’s nodules"). * **Positioning:** Remember the "Rule of 1/3": Junction of anterior 1/3 and posterior 2/3 is the classic site for nodules.

Q: A patient who is a teacher by profession presents to the clinic with hoarseness of voice. What is the most likely diagnosis for this patient?

Vocal nodule. ***Vocal nodules***- This is the most likely diagnosis as **vocal nodules** (or singer's nodules) are typically caused by chronic **vocal strain** and **misuse**, common in professions like teaching.- Nodules present as bilateral, symmetrical lesions at the junction of the anterior one-third and posterior two-thirds of the vocal cords, leading to persistent **hoarseness**.*Vocal polyp*- Usually presents as a **unilateral** mass and is often caused by a single acute instance of **vocal trauma** (e.g., screaming) or long-term irritants like smoking.- While causing hoarseness, polyps are less commonly associated with the chronic, bilateral lesions seen from professional voice abuse compared to nodules.*Vocal cyst*- These are retention cysts or epidermoid cysts, which are usually **unilateral** and are not primarily linked to the pathogenesis of professional voice overuse, although they can cause persistent hoarseness.- Cysts are formed when a mucus gland duct is blocked or when keratin builds up, and they are typically located sub-epithelially, appearing deeper than nodules.*Reinke's oedema*- This condition is almost exclusively associated with **heavy smoking** and is characterized by a gelatinous, bilateral swelling of the superficial lamina propria (*Reinke's space*).- While it causes severe hoarseness, the primary predisposing factor (smoking) is absent in the prompt, making nodules (vocal abuse) a more probable primary diagnosis based on the profession.

Q: Which of the following studies is shown below?

Stroboscopy. ***Stroboscopy*** - The image displays multiple sequential frames of the vocal cords during phonation, along with a corresponding **waveform analysis** of vowel production, which is characteristic of **videostroboscopy**. - This technique uses a flashing light synchronized with the vocal fold vibration to create a slow-motion effect, allowing detailed visualization of mucosal wave and vocal fold closure patterns. *Laryngoscopy* - **Laryngoscopy**, in its basic form, provides a direct view of the **larynx and vocal cords** but does not typically capture the rapid vibratory motion in slow motion. - While laryngoscopy is part of the stroboscopy procedure, the specific display of slow-motion vocal fold movement alongside a waveform indicates a more specialized technique. *Video laryngoscopy* - **Video laryngoscopy** (including devices like GlideScope) is a method used for **tracheal intubation**, which involves a laryngoscope with video capability for better visualization of the glottis during tube placement. - It is not a diagnostic imaging technique for assessing vocal fold function or vibratory patterns. *Cineangiography* - **Cineangiography** is a diagnostic procedure used to visualize **blood vessels** and blood flow within the body, typically associated with cardiovascular imaging. - It involves injecting a contrast agent and taking rapid X-ray sequences to create a moving picture of blood flow, which is entirely unrelated to vocal cord examination.

Q: A 20-year-old lady singer of a rock band develops diplophonia after a performance. The laryngoscopy image is shown below. What is the most likely diagnosis?

Vocal nodule. ***Vocal nodule*** - The image shows **bilateral, symmetrical swellings** at the junction of the anterior and middle third of the vocal cords, characteristic of **vocal nodules** also known as **singer's nodes**. - The patient's profession as a **singer** and the symptom of **diplophonia** (double voice) after a performance are classic presentations of vocal cord injury due to **vocal abuse**. *Vocal polyp* - A **vocal polyp** is typically **unilateral**, larger than a nodule, and can be sessile or pedunculated; it does not present as symmetric bilateral lesions. - While vocal polyps can also be caused by vocal abuse and lead to dysphonia, their distinct morphology differs from the symmetrical lesions seen. *Reinke edema* - **Reinke edema** (polypoid corditis) involves diffuse **edematous swelling** along the entire length of the membranous vocal folds, often associated with smoking and a deep, husky voice. - The visible lesions are localized, distinct, and bilateral, not a diffuse swelling of the vocal fold subepithelial space. *Contact ulcer* - **Contact ulcers** are lesions on the medial surface of the arytenoid cartilages, at the posterior third of the vocal cords, usually due to **acid reflux** or prolonged vocal abuse with hard glottal attacks. - The lesions in the image are located on the vibrating part of the vocal cords, not in the posterior cartilaginous portion.

Q: A singer presents with difficulty singing at a high pitch. On examination, bowing of the vocal cord is observed on the right side. Which of the following muscles has likely been compromised?

Cricothyroid. ***Cricothyroid*** - The **cricothyroid muscle** is primarily responsible for **tensioning and elongating the vocal cords**, which is crucial for increasing vocal pitch. - Damage to this muscle or its innervation (superior laryngeal nerve) results in an inability to reach higher pitches and can cause **vocal cord bowing** due to reduced tension. *Posterior cricoarytenoid* - This muscle is the **primary abductor** of the vocal cords, meaning it opens the vocal cords for breathing. - Compromise would lead to difficulty breathing or a paralyzed vocal cord in the adducted position, not bowing with difficulty singing high notes. *Lateral cricoarytenoid* - The **lateral cricoarytenoid muscle** is a **vocal cord adductor** and rotator, bringing the vocal cords together to regulate voice intensity. - Dysfunction typically results in a weak and breathy voice, or difficulty bringing the cords together, not specifically difficulty with high pitch. *Thyroarytenoid* - The **thyroarytenoid muscle** (which includes the vocalis muscle) acts to **relax and shorten the vocal cords**, lowering pitch and modulating vocal cord tension. - Dysfunction would primarily lead to difficulty with lower pitches or a hoarse voice, as it prevents proper relaxation of the vocal cords.

Q: Dysphonia plica ventricularis is produced from:

Ventricular fold. ***Ventricular fold*** - **Dysphonia plica ventricularis**, also known as **ventricular dysphonia** or **false vocal cord dysphonia**, occurs when the **ventricular folds** (false vocal cords) vibrate inappropriately during phonation. - This condition often results in a **hoarse**, rough, or strained voice quality, as the false vocal cords are not designed for regular vibratory function in voice production. *Vocal cord* - The **true vocal cords** are the primary structures responsible for producing sound through precise vibration and approximation during phonation. - Dysphonia originating from the **true vocal cords** would typically be described by terms like vocal fold paralysis, nodules, or polyps, not "plica ventricularis." *Arytenoid* - The **arytenoid cartilages** are crucial in vocal cord movement and tension through their articulation with the cricoid cartilage. - While they influence voice production, they do not directly vibrate to produce sound themselves; rather, they position the vocal cords. *Epiglottis* - The **epiglottis** is a leaf-shaped cartilage that primarily functions to prevent food and liquid from entering the trachea during swallowing. - It plays no direct role in voice generation through vibration; its involvement in phonation is generally limited to resonance or protection.

Q: The primary goal of Type 1 thyroplasty is:

Medialisation of vocal cord. ***Medialisation of vocal cord*** - **Type 1 thyroplasty** (also known as medialization laryngoplasty) aims to push the vocal cord medially, improving vocal cord closure - This procedure is primarily used to treat **unilateral vocal cord paralysis** or paresis, where one vocal cord cannot move sufficiently to meet the other for voice production - By medializing the paralyzed vocal cord, the procedure restores glottic competence and improves voice quality *Lateralisation of vocal cord* - Lateralisation of the vocal cord would worsen a glottal gap and lead to a more breathy voice or aphonia - This is generally not a desired outcome for voice improvement but might be considered in cases of severe airway obstruction (e.g., Type 2 thyroplasty for bilateral vocal cord paralysis) *Vocal cord shortening* - Vocal cord shortening primarily affects pitch, typically lowering it, and is achieved through procedures like cricothyroid approximation or by altering tension - This is not the main goal of Type 1 thyroplasty, which focuses on closure rather than length *Vocal cord lengthening* - Vocal cord lengthening is done to increase vocal pitch, often through procedures that increase vocal cord tension, such as cricothyroid approximation - This is a separate surgical goal from improving vocal cord apposition, which is the aim of Type 1 thyroplasty
