A patient presents with recurrent episodes of postnasal drip, chronic cough, and halitosis. Nasal endoscopy reveals a foul-smelling, yellowish discharge draining from the middle meatus. Which of the following conditions is most likely responsible for this presentation?
Correct Answer: A
Rationale: The patient's presentation of recurrent episodes of postnasal drip, chronic cough, halitosis, and foul-smelling, yellowish discharge from the middle meatus is highly suggestive of chronic rhinosinusitis. The presence of nasal polyps further supports this diagnosis. Chronic rhinosinusitis with nasal polyps is characterized by inflammation of the paranasal sinuses, leading to symptoms such as nasal congestion, postnasal drip, cough, and a reduced sense of smell. The yellowish discharge and foul odor are typical findings in cases of chronic rhinosinusitis with secondary bacterial infection. Nasal endoscopy may reveal edematous nasal mucosa and polyps obstructing the middle meatus, contributing to the symptoms described by the patient. Management typically involves a combination of medical therapies such as intranasal corticosteroids, saline irrigation, and antibiotics, and in some cases, surgical intervention
