ENT Rhinology and Sinonasal Disorders

Question 1

According to the EPOS guidelines, chronic rhinosinusitis (CRS) is defined as inflammation of the nose and paranasal sinuses lasting at least how long?

Accepted Answer

12 weeks

Answer

EPOS defines CRS as sinonasal inflammation persisting for 12 weeks or longer despite treatment attempts.

Question 2

Which of the following is the most common causative organism in acute bacterial rhinosinusitis?

Accepted Answer

Streptococcus pneumoniae

Answer

Streptococcus pneumoniae is the most common bacterial pathogen in acute bacterial rhinosinusitis, followed by Haemophilus influenzae.

Question 3

Samter's triad (Aspirin-Exacerbated Respiratory Disease) consists of which combination?

Accepted Answer

Asthma, nasal polyposis, and NSAID sensitivity

Answer

Samter's triad comprises asthma, nasal polyposis, and sensitivity to aspirin/NSAIDs, driven by arachidonic acid pathway dysregulation.

Question 4

The ostiomeatal complex (OMC) is clinically important in rhinosinusitis because it serves as the drainage pathway for which group of sinuses?

Accepted Answer

Frontal, maxillary, and anterior ethmoid sinuses

Answer

The OMC is the final common drainage pathway for the frontal, maxillary, and anterior ethmoid sinuses; obstruction at this point predisposes to sinusitis in these regions.

Question 5

Which imaging modality is considered the gold standard for evaluating sinonasal anatomy before functional endoscopic sinus surgery (FESS)?

Accepted Answer

Non-contrast CT of the paranasal sinuses

Answer

Non-contrast CT of the paranasal sinuses provides the bony detail and anatomic roadmap essential for safe FESS planning.
