Mixed Deck — All ENT Topics Flashcards

How should challenges in safety and compliance be addressed?

Answer: Apply systematic problem-solving, seek expert guidance when needed, and document decisions

Systematic problem-solving combined with appropriate consultation and documentation ensures challenges are addressed effectively.

What is the definitive treatment for an acquired cholesteatoma?

Answer: Tympanomastoidectomy

Cholesteatoma keeps growing and eroding bone, so surgical removal by tympanomastoidectomy is the definitive treatment.

What quality assurance measure supports communication and documentation?

Answer: Regular self-assessment, peer review, and adherence to established standards

Ongoing quality assurance through self-assessment, peer review, and standards adherence ensures continuous improvement.

Where does the nasolacrimal duct open?

Answer: Inferior meatus

The nasolacrimal duct opens into the inferior meatus beneath the inferior turbinate, guarded by Hasner's valve.

How should industry best practices knowledge be maintained and updated?

Answer: Through continuous professional development, current literature review, and professional networking

Professional competence requires ongoing development through education, literature review, and engagement with the professional community.

A patient has trismus, uvular deviation, and a peritonsillar abscess. What is the initial management?

Answer: Needle aspiration or incision and drainage plus antibiotics

Drainage by aspiration or incision, combined with antibiotics, is the standard first-line treatment for peritonsillar abscess.

What ethical standard governs industry best practices practice?

Answer: Adherence to the profession's code of ethics and applicable laws and regulations

Professional ethics codes and applicable laws provide the framework for ethical practice in every professional field.

How should professionals apply safety and compliance in daily practice?

Answer: Consistently integrate best practices into every aspect of professional work

Consistent application of professional standards ensures quality outcomes and builds professional credibility.

What is the preferred test to rule out vestibular schwannoma in a patient with asymmetric sensorineural hearing loss?

Answer: Gadolinium-enhanced MRI of the internal auditory canals

Contrast-enhanced MRI is the gold standard for finding retrocochlear lesions, including small intracanalicular tumors.

The Keros classification on preoperative CT measures what?

Answer: Height of the lateral lamella of the cribriform plate (olfactory fossa depth)

The Keros classification grades olfactory fossa depth (type I 1-3 mm, type II 4-7 mm, type III 8-16 mm); deeper fossae carry a higher risk of skull base injury.

A flat (Type B) tympanogram with an abnormally large ear canal volume most likely indicates which finding?

Answer: Tympanic membrane perforation or patent PE tube

A large physical volume with a flat trace means the probe is measuring the canal plus middle ear space, as seen with a perforation or open tube.

The sphenoid sinus ostium drains into which area?

Answer: Sphenoethmoidal recess

The sphenoid sinus drains into the sphenoethmoidal recess, which lies medial to the superior turbinate and above it.

What is the most common malignant tumor of the parotid gland?

Answer: Mucoepidermoid carcinoma

Mucoepidermoid carcinoma is the most common malignant salivary gland tumor overall and the most frequent malignancy of the parotid gland, classified as low, intermediate, or high grade.

Which muscle is the only abductor of the vocal folds?

Answer: Posterior cricoarytenoid

The posterior cricoarytenoid rotates the arytenoids outward to open the glottis.

Which medication is commonly prescribed for allergic rhinitis?

Answer: Fluticasone

Fluticasone is a corticosteroid medication commonly prescribed as a nasal spray for allergic rhinitis. It works by reducing inflammation in the nasal passages, thereby alleviating symptoms such as sneezing, runny nose, nasal congestion, and itching associated with allergies. Unlike antihistamines, it directly targets the inflammatory response to provide relief.

What surgical procedure corrects a deviated nasal septum?

Answer: Septoplasty

Septoplasty is a surgical procedure specifically designed to correct a deviated nasal septum, which is the wall between the nostrils. By straightening the septum, septoplasty improves airflow through the nose. This alleviates symptoms like chronic nasal obstruction, difficulty breathing, and recurrent sinus infections caused by the deviation.

Which structure is primarily responsible for voice production?

Answer: Vocal cords

The vocal cords, also known as vocal folds, are two bands of smooth muscle tissue located within the larynx (voice box). Their primary function is voice production, or phonation. When air from the lungs passes through the vibrating vocal cords, it creates sound, which is then articulated by the mouth, tongue, and pharynx to form speech.

When communicating with a patient who has severe hearing loss and reads lips, which practice is best?

Answer: Face the patient in good lighting and speak clearly at a normal pace

Lip-readers need a clear, well-lit view of the speaker's face and natural articulation.

A patient has brief vertigo when rolling over in bed. On right Dix-Hallpike testing, upbeating torsional nystagmus starts after a short delay and fades within 30 seconds. What is the best next step?

Answer: Epley canalith repositioning maneuver

Upbeating torsional nystagmus that starts after a delay and fades on Dix-Hallpike points to posterior canal BPPV, which is treated with the Epley maneuver.

Nasal polyposis is most strongly associated with which underlying condition?

Answer: Type 2 eosinophilic inflammation

Nasal polyps arise predominantly from type 2 (Th2-mediated) eosinophilic inflammation, as evidenced by high tissue eosinophil and IL-5 levels.
