Voice Therapy Indian Medical PG Practice Questions and MCQs
Question 1: Treatment of choice in early vocal nodule is:
- A. Voice rest and speech therapy (Correct Answer)
- B. Cryotherapy
- C. Microlaryngoscopic removal
- D. Radical excision
Explanation: ***Voice rest and speech therapy*** - In cases of **early vocal nodules**, conservative management with **voice rest** and **speech therapy** is the primary treatment. - This approach aims to reduce vocal trauma and modify vocal habits, allowing the nodules to resolve naturally without surgical intervention. *Cryotherapy* - **Cryotherapy** involves freezing and destroying abnormal tissue and is not a standard treatment for vocal nodules. - Its application is more common for superficial lesions, such as certain skin cancers or warts, not benign vocal cord growths. *Microlaryngoscopic removal* - Although **microlaryngoscopic removal** is an option for vocal nodules, it is usually reserved for larger, more established nodules that have not responded to conservative measures. - This is an invasive procedure and is not the **first-line treatment** for early-stage nodules where non-surgical methods are often effective. *Radical excision* - **Radical excision** is a surgical technique for removing lesions, but it is not typically applied to vocal nodules. - The term "radical excision" is often used in the context of oncological procedures involving extensive tissue removal, not benign vocal cord lesions.
Question 2: Joseph Wolpe developed the following behaviour management technique -
- A. Flooding
- B. Aversion therapy
- C. Desensitization (Correct Answer)
- D. Modeling
Explanation: ***Desensitization*** - **Joseph Wolpe** is credited with developing **systematic desensitization** in the 1950s, a behavior therapy technique used to treat phobias and anxiety disorders. - This technique involves **gradually exposing** an individual to a feared object or situation in a **hierarchical manner** while teaching them **relaxation techniques** (such as progressive muscle relaxation) to overcome anxiety responses. - Based on the principle of **reciprocal inhibition** - the idea that relaxation and anxiety are incompatible responses. *Flooding* - **Flooding** is an exposure-based behavioral technique where the patient is exposed to the **most feared stimulus immediately** at full intensity, rather than gradually. - While also an exposure therapy, it differs from Wolpe's systematic desensitization as it involves **intense, prolonged exposure** without gradual progression. - Associated with **Thomas Stampfl** and is also called **implosion therapy** when done imaginally. *Aversion therapy* - **Aversion therapy** is a behavioral technique that pairs an **undesirable behavior with an unpleasant stimulus** to reduce that behavior. - Used historically for conditions like alcoholism and smoking cessation, but not developed by Wolpe. - Based on **classical conditioning** principles but uses punishment rather than gradual exposure and relaxation. *Modeling* - **Modeling** (observational learning or vicarious learning) is a behavior management technique where an individual learns by observing others. - Extensively studied by **Albert Bandura** through his social learning theory and famous Bobo doll experiments. - Often used to teach new behaviors or reduce fears by observing a fearless peer or model, but this is not Wolpe's primary contribution.
Question 3: Which imaging and Doppler techniques are combined in duplex ultrasonography?
- A. B-mode imaging and pulse-wave Doppler examination (Correct Answer)
- B. M-mode imaging and power Doppler examination
- C. M-mode imaging and waveform analysis
- D. A-mode imaging and pulse-wave Doppler examination
Explanation: ***B-mode imaging and pulse-wave Doppler examination*** - **B-mode imaging** provides a real-time, two-dimensional grayscale image of the vessel structure. - **Pulse-wave Doppler** assesses blood flow direction, velocity, and characteristics within the visualized vessel. *M-mode imaging and power Doppler examination* - **M-mode imaging** is primarily used for visualizing moving structures over time (e.g., cardiac valves), not for detailed vessel anatomy. - **Power Doppler** is sensitive to the presence of blood flow but does not provide information on flow direction or velocity, which is crucial for full duplex ultrasound. *M-mode imaging and waveform analysis* - **M-mode imaging** is not the primary imaging modality for evaluating vascular structures in duplex ultrasonography. - While waveform analysis is part of Doppler interpretation, combining it with M-mode imaging does not constitute duplex ultrasonography. *A-mode imaging and pulse-wave Doppler examination* - **A-mode imaging** represents echoes as spikes on a single line, providing limited anatomical information and is not used for vascular assessment. - Although pulse-wave Doppler is a component, the primary imaging mode is incorrect for duplex ultrasonography.
Question 4: Most definitive treatment for large symptomatic acoustic neuroma is
- A. Steroids
- B. Radiotherapy
- C. Anti-neoplastic drugs
- D. Surgery (Correct Answer)
Explanation: ***Surgery*** - **Surgical resection** is the most definitive treatment for **large, symptomatic acoustic neuromas** (typically >3 cm), especially those causing **mass effect** on the brainstem and cerebellum. - It aims for **complete tumor removal** to alleviate symptoms (hearing loss, facial nerve dysfunction, brainstem compression) and prevent further neurological compromise. - Surgical approaches include **translabyrinthine**, **retrosigmoid**, or **middle cranial fossa** approaches depending on tumor size and hearing status. *Steroids* - **Steroids** may be used to manage acute symptoms like **edema** or inflammation associated with the tumor, but they are not a definitive treatment. - They do not address the underlying tumor growth or remove the mass. - Used only as **temporary symptomatic relief** or perioperative adjunct. *Radiotherapy* - **Stereotactic radiosurgery** (Gamma Knife, CyberKnife) is effective for **small to medium-sized tumors** (<3 cm) with good tumor control rates. - For **large tumors**, radiotherapy is **insufficient** as it only aims to **control tumor growth** rather than remove the mass, and cannot provide immediate decompression. - Large tumors with mass effect require **surgical decompression** for definitive management. *Anti-neoplastic drugs* - **Anti-neoplastic drugs** (chemotherapy) are generally **ineffective** against acoustic neuromas, which are **benign vestibular schwannomas**. - They are typically reserved for malignant tumors or specific genetic syndromes (e.g., bevacizumab in NF2-related schwannomas), but not for standard sporadic acoustic neuromas. - Chemotherapy is **not a definitive treatment** for these benign tumors.
Question 5: Hyponasal voice is seen in all except?
- A. Adenoids
- B. Nasal polyp
- C. Deviated nasal septum
- D. Cleft lip (Correct Answer)
Explanation: ***Cleft lip*** - A **cleft lip** primarily affects the appearance of the lip and a portion of the nose but doesn't typically obstruct the nasal passages to cause a hyponasal voice. - The voice quality in individuals with a cleft lip, without an associated cleft palate, is usually normal. *Adenoids* - **Enlarged adenoids** can obstruct the nasopharyngeal airway, leading to reduced nasal resonance and a **hyponasal (rhinolalia clausa)** voice. - This obstruction prevents air from exiting through the nose during speech, making sounds like 'm' and 'n' sound like 'b' and 'd'. *Nasal polyp* - **Nasal polyps** can physically block the nasal passages, impairing airflow through the nose during speech. - This blockage leads to a reduction in nasal resonance, resulting in a **hyponasal voice**. *Deviated nasal septum* - A **deviated nasal septum** can significantly narrow one or both nasal passages, restricting airflow. - This structural obstruction can cause a **hyponasal voice** due to reduced nasal resonance.
Question 6: The voice is not affected in which of the following conditions?
- A. Unilateral abductor palsy (Correct Answer)
- B. Unilateral adductor palsy
- C. Partial abductor palsy
- D. Total adductor palsy
Explanation: In phoniatrics, the quality of voice depends on the ability of the vocal cords to meet in the midline (**adduction**) for vibration. ### **Explanation of the Correct Answer** **A. Unilateral abductor palsy:** In this condition, the affected vocal cord is paralyzed in the **median (midline) position** because it cannot move outward (abduct). Since the paralyzed cord is already at the midline, the healthy cord can easily meet it during phonation. As a result, the glottic gap is closed perfectly, and the **voice remains normal**. This condition is often asymptomatic and may only present with mild exertional dyspnea (stridor). ### **Why the Other Options are Incorrect** * **B. Unilateral adductor palsy:** The affected cord remains in the **paramedian or lateral position** and cannot move to the midline. This creates a large glottic gap during speech, leading to a **breathy, weak voice (hoarseness)**. * **C. Partial abductor palsy:** According to **Semon’s Law**, in progressive lesions of the recurrent laryngeal nerve, abductor fibers are injured first. This results in the cord being stuck in a position that interferes with the symmetry of vibration, leading to varying degrees of **hoarseness**. * **D. Total adductor palsy:** This involves a complete failure of the cords to approximate, leading to significant **aphonia** (loss of voice) or severe breathiness. ### **Clinical Pearls for NEET-PG** * **Semon’s Law:** In progressive recurrent laryngeal nerve (RLN) injury, abductors (Posterior Cricoarytenoid) are paralyzed before adductors. * **Wagner and Grossman Hypothesis:** If the Superior Laryngeal Nerve (SLN) is intact, the cricothyroid muscle keeps the paralyzed cord in the **paramedian** position. * **Position of Cords:** * Unilateral RLN palsy: Paramedian position. * Bilateral RLN palsy: Median/Paramedian (Airway emergency, but voice is often good). * Combined RLN + SLN palsy: **Cadaveric position** (Intermediate position).
Question 7: A patient complains of sharp shooting pain in the pharynx and tonsil. On examination, a trigger zone is found in the tonsillar area. What is the diagnosis?
- A. Sphenopalatine neuralgia
- B. Paratrigeminal neuralgia
- C. Glossopharyngeal neuralgia (Correct Answer)
- D. Trigeminal neuralgia
Explanation: **Explanation:** The clinical presentation of **sharp, shooting (paroxysmal) pain** localized to the **pharynx and tonsillar area**, initiated by a **trigger zone** in the tonsil, is the classic hallmark of **Glossopharyngeal Neuralgia**. **1. Why Glossopharyngeal Neuralgia is correct:** This condition involves the 9th cranial nerve. The pain is typically unilateral and occurs in the distribution of the glossopharyngeal nerve (posterior third of the tongue, tonsillar fossa, pharynx, and beneath the angle of the jaw). Common triggers include swallowing, talking, coughing, or touching the tonsillar area. **2. Why other options are incorrect:** * **Sphenopalatine neuralgia (Sluder’s Neuralgia):** Characterized by pain in the lower face, nose, and orbit, often associated with nasal congestion or rhinorrhea, rather than pharyngeal triggers. * **Paratrigeminal neuralgia (Raeder’s Syndrome):** Presents as trigeminal pain (usually V1/V2 distribution) accompanied by oculosympathetic palsy (Horner’s syndrome). * **Trigeminal neuralgia (Tic Douloureux):** The most common facial neuralgia, but the pain is located in the distribution of the 5th cranial nerve (usually maxillary or mandibular branches). Trigger zones are typically on the skin of the face or the gingiva, not the pharynx. **High-Yield Clinical Pearls for NEET-PG:** * **Eagle’s Syndrome:** A key differential diagnosis where an elongated styloid process irritates the glossopharyngeal nerve, causing similar pain. * **Treatment:** Medical management is the first line, primarily using **Carbamazepine**. * **Surgical Management:** If medical therapy fails, **Microvascular Decompression (MVD)** of the 9th nerve or rhizotomy is performed. * **Vagal Association:** In rare cases, glossopharyngeal neuralgia can trigger the carotid sinus reflex, leading to bradycardia or syncope.
Question 8: A young man whose voice has not been broken is called:
- A. Puberphonia (Correct Answer)
- B. Androphonia
- C. Plica ventricularis
- D. Functional aphonia
Explanation: **Explanation:** **Puberphonia** (also known as Mutational Falsetto) is a functional voice disorder where a male continues to use a high-pitched pre-pubertal voice despite having a normal, adult-sized larynx. During puberty, the male larynx grows significantly under the influence of testosterone, and the vocal cords lengthen and thicken. Puberphonia occurs when the individual resists this change, often due to psychological factors or difficulty adjusting to the new pitch, resulting in the persistent use of the "unbroken" voice. **Analysis of Incorrect Options:** * **Androphonia:** This refers to a female having an abnormally low-pitched, masculine voice. It is often caused by virilization (e.g., hormonal therapy or tumors) or Reinke’s edema. * **Plica Ventricularis (Ventricular Dysphonia):** This occurs when the false vocal cords (ventricular folds) are used for phonation instead of the true vocal cords. It results in a rough, low-pitched, and strained voice. * **Functional Aphonia:** This is a conversion disorder where the patient speaks only in a whisper despite having normal laryngeal anatomy and adduction during coughing. It is typically triggered by emotional stress. **High-Yield Clinical Pearls for NEET-PG:** * **Laryngeal Findings:** In puberphonia, the larynx is anatomically normal. On stroboscopy, the vocal cords are often tense and thin. * **Gutzmann’s Test:** This is the diagnostic/therapeutic maneuver where downward pressure is applied on the thyroid cartilage to relax the vocal cords, resulting in a lower pitch. * **Treatment:** The primary treatment is **Voice Therapy (Speech therapy)**, specifically the "Glottal Fry" technique. Type 3 Thyroplasty (Relaxation Thyroplasty) is reserved for resistant cases.
Question 9: Type I thyroplasty is indicated for which of the following vocal cord conditions?
- A. Vocal cord medialization (Correct Answer)
- B. Vocal cord lateralization
- C. Vocal cord shortening
- D. Vocal cord lengthening
Explanation: **Explanation:** **Type I Thyroplasty**, also known as **Isshiki Type I**, is a surgical procedure designed for **vocal cord medialization**. It is primarily indicated for patients with **unilateral vocal cord paralysis** (where the cord is fixed in an abducted or paramedian position) or vocal cord atrophy. 1. **Why Option A is Correct:** The procedure involves creating a small window in the thyroid cartilage and inserting a spacer (Silastic block or Gore-Tex) to push the paralyzed vocal cord toward the midline. This allows the healthy vocal cord to make contact with the paralyzed one during phonation, thereby improving voice quality, reducing breathiness, and preventing aspiration. 2. **Why Other Options are Incorrect:** * **Type II (Lateralization):** Indicated for adductor spasmodic dysphonia to move the cords apart. * **Type III (Shortening/Relaxation):** Used to lower the vocal pitch (e.g., in Mutational Falsetto/Puberphonia) by shortening or relaxing the cords. * **Type IV (Lengthening/Tension):** Used to raise the vocal pitch (e.g., in Androphonia or for gender reassignment) by tensing the cricothyroid distance. **High-Yield Clinical Pearls for NEET-PG:** * **Isshiki Classification:** Remember the sequence: **1-Medial, 2-Lateral, 3-Lower pitch, 4-Higher pitch.** * **Prerequisite:** Type I Thyroplasty is usually performed under **local anesthesia** so the surgeon can monitor the patient's voice quality in real-time to achieve optimal positioning. * **Alternative:** Injection Laryngoplasty (using Teflon or Gelfoam) is another method for medialization but is often temporary compared to Thyroplasty.
Question 10: In a patient with hypertrophied adenoids, what voice abnormality is typically observed?
- A. Rhinolalia clausa (Correct Answer)
- B. Rhinolalia apea
- C. Hot potato voice
- D. Staccato voice
Explanation: ### Explanation **1. Why Rhinolalia Clausa is Correct:** Rhinolalia clausa (Hyponasality) occurs when there is an **obstruction** in the nasal passage or nasopharynx, preventing normal nasal resonance. In children with **hypertrophied adenoids**, the lymphoid tissue physically blocks the nasopharynx. Consequently, nasal consonants like /m/, /n/, and /ng/ are substituted by oral sounds (/b/, /d/, and /g/). For example, "mom" sounds like "bob." **2. Analysis of Incorrect Options:** * **Rhinolalia Aperta (Hypernasality):** This is the opposite of clausa. It occurs due to an **inability to seal off** the nasopharynx from the oropharynx, leading to excessive air escape through the nose. It is typically seen in **cleft palate**, short soft palate, or palatal paralysis (e.g., post-diphtheritic). * **Hot Potato Voice:** This describes a muffled, thick voice as if the patient is speaking with a hot potato in their mouth. It is the hallmark of **Peritonsillar abscess (Quinsy)**, but can also be seen in epiglottitis or base-of-tongue tumors. * **Staccato Voice:** Characterized by jerky, disconnected speech where words are broken into syllables. This is a neurological sign typically associated with **Multiple Sclerosis** or cerebellar lesions (Scanning speech). **3. Clinical Pearls for NEET-PG:** * **Adenoid Facies:** Chronic mouth breathing due to adenoid hypertrophy leads to a characteristic appearance: elongated face, dull expression, open mouth, crowded teeth, and high-arched palate. * **Eustachian Tube Dysfunction:** Adenoids can block the ET opening, leading to **Otitis Media with Effusion (Serous Otitis Media)** and conductive hearing loss. * **Gold Standard Diagnosis:** Flexible nasopharyngoscopy is the preferred diagnostic tool, though X-ray soft tissue nasopharynx (lateral view) is a common exam-based investigation.
