Chronic Rhinosinusitis Phenotype with Nasal Polyps Overview

Chronic rhinosinusitis phenotype with nasal polyps is a well-defined clinical condition marked by ongoing inflammation of the nasal and sinus mucosa, identified through a combination of patient symptoms and objective diagnostic evidence. This condition is distinguished by the presence of benign, inflammatory polyps that develop within the sinonasal passages, most often on both sides. Although nasal polyps can also occur in diseases like cystic fibrosis or certain cancers, their occurrence in this context signifies a specific inflammatory form of chronic rhinosinusitis. These polyps are soft tissue growths that extend into the nasal cavity, usually arise bilaterally, and commonly originate from the ethmoid sinuses.

Individuals with chronic rhinosinusitis with nasal polyps often experience a range of persistent symptoms that impact daily functioning and quality of life. These include facial pain or pressure, nasal congestion, and a reduced or lost sense of smell. Many also report a runny nose, postnasal drip leading to throat irritation or soreness, and headaches. Discomfort may extend to the upper teeth, and symptoms like snoring are common due to nasal blockage.

Chronic Rhinosinusitis Phenotype with Nasal Polyps Diagnosis and Treatment Algorithm

Diagnosis of chronic rhinosinusitis phenotype with nasal polyps requires objective confirmation using either a sinus CT scan or nasal endoscopy, which also helps differentiate between the polyp and non-polyp phenotypes. In adults, nasal polyps should be present in both nasal cavities to support a diagnosis of chronic rhinosinusitis phenotype with nasal polyps; the presence of a unilateral polyp warrants further evaluation to rule out other potential causes, including malignancy.

Management of chronic rhinosinusitis phenotype with nasal polyps involves a combination of medical and surgical interventions. First-line treatments include intranasal corticosteroids and saline irrigations to reduce inflammation and improve sinus drainage. Oral corticosteroids may be used short term for more severe symptoms but carry a risk of systemic side effects. Antibiotics are generally reserved for acute bacterial infections and offer limited benefit in reducing polyp size.

For patients who do not respond adequately to medical therapy, functional endoscopic sinus surgery (FESS) is considered to remove obstructive polyps and improve access for topical therapies. However, recurrence is common, especially in patients with comorbid asthma.

Recently approved biologics have transformed the treatment landscape. The US FDA has approved DUPIXENT, NUCALA, and XOLAIR as add-on maintenance therapies for chronic rhinosinusitis with nasal polyps in adults with inadequate response to corticosteroids. These targeted agents reduce polyp size, improve symptom control, and lower surgical needs by modulating underlying inflammatory pathways. Their approval marks a shift toward more personalized and durable disease management in chronic rhinosinusitis phenotype with nasal polyps.
