Defining Treatment Failure in Chronic Rhinosinusitis

October 27, 2026

One of the most difficult inflammatory disorders to treat is chronic sinusitis, mainly due to the complex reasons behind persistent inflammation, anatomical variants, and patient-specific immune responses associated with the disease. When chronic sinus outcomes do not achieve the expectations of the doctor and patient, the definition of CRS treatment failure should be re-examined and expanded to include underlying causes that may have been overlooked, as well as the need for individualized adjustments in diagnosis and treatment.

Refractory Sinusitis Definition and Chronic Sinus Outcomes

Refractory sinusitis is chronic sinus inflammation that fails to improve with typical treatments. Symptoms, such as congestion, facial pressure, nasal discharge, and reduced sense of smell, often last 12 weeks or longer. Causes of refractory sinusitis generally involve a deviated septum, polyps, immune-driven inflammation, allergies, asthma, and less common underlying conditions.

CRS treatment failure may be said to occur after standard approaches fail to provide long-term relief for refractory sinusitis. However, clinicians should reassess the probability of underlying factors, including marginal structural abnormalities, immunodeficiencies, or undiagnosed comorbid conditions, and adjust treatment plans to the patient’s specific health condition to improve symptom control.

Comparing SNOT‑22 and Lund‑Kennedy in Measuring Refractory Sinusitis Severity

Objective measures provide more insight than symptom reports in chronic rhinosinusitis assessment. The Sino‑Nasal Outcome Test‑22 (SNOT‑22) is a widely used patient‑reported questionnaire that summarizes symptom burden and quality of life in CRS patients. However, studies have shown that SNOT‑22 scores may not align adequately with physical findings of disease severity.

In contrast, the Lund‑Kennedy endoscopic score directly evaluates mucosal inflammation, polyps, edema, and discharge seen on nasal endoscopy, offering a more structured objective assessment that can reveal ongoing disease despite modest symptom reports.

Avoiding CRS Treatment Failure to Optimize Chronic Sinus Outcomes

CRS symptoms often emerge from other inflammatory airway conditions, which emphasize the importance of viewing the airway as a unified airway. Asthma, allergic rhinitis, and aspirin-exacerbated respiratory disease are common among CRS patients and can influence disease severity and treatment response.

In cohorts receiving biologic therapy for severe nasal polyps, over 70% of patients have asthma. Assessing the possibility of a CRS treatment failure should involve collaboration among otolaryngologists, allergists, and immunologists. Surgeons focus on anatomical outcomes, while sinus specialists evaluate systemic inflammation. Such teamwork can clarify whether structural issues or advanced medical management guide development of future treatment protocols.

Toward a Standardized Definition of CRS Treatment Failure

Clearer, measurable thresholds for treatment failure would benefit both clinicians and patients. Objective markers, such as persistent endoscopic inflammation, validated symptom scores that have not improved, and ongoing mucosal edema despite maximal medical therapy, provide clinicians with a more reliable basis for deciding when a current treatment plan is ineffective.

Early recognition of treatment failure prevents unnecessary interventions and directs ENT specialists toward therapies that achieve sustained mucosal control and long-term symptom management of refractory sinusitis.

Learn how ENT doctors can approach complex cases when standard treatment algorithms fall short, using collaboration, research, and personalized airway care.

Rural and Underserved Access to Multidisciplinary Airway Expertise

September 22, 2026

Inflammatory airway diseases can impact a patient's quality of life. Untreated conditions leave patients struggling to breathe, coughing regularly, and feeling unwell for months at a time. Airway disease management has undergone significant changes in recent years. Treating airway diseases has become increasingly complex, despite improvements in methodologies and technologies. In rural and underserved regions, many patients lack access to specialty care. Key Takeaways: Providing high-quality care to patients with airway disease requires collaboration across specialties. It is important to expand rural ENT access and access to multidisciplinary clinics. Clinicians in rural communities can improve patient outcomes through collaborations and with creative solutions that expand airway care. The Need for Multidisciplinary Airway Care Airway diseases affect multiple systems of the body and thus are treated by different types of physicians. Allergists, primary care doctors, pulmonologists, and ENT physicians all play a role in caring for patients with airway conditions. Physicians who can facilitate multidisciplinary care can improve diagnostic accuracy while also helping to ensure better patient outcomes. Challenges in Rural and Underserved Communities Rural ENT access is spotty at best. Many rural areas lack specialty physicians and often, patients must travel long distances to tertiary medical centers where they receive care. As a result, patients with limited transportation options may experience delays in diagnosis and care. Sometimes, these specialty care disparities can leave primary care providers to manage complex airway conditions on their own. In areas where insurance coverage is limited, and referral networks are fragmented, patients may struggle with their conditions without treatment at all. The Consequences of These Limitations Delays in diagnosis and treatment mean poor management of chronic conditions and increased reliance on treatment from acute care settings. Under this system, patients become frustrated as they lean on ineffective treatment methods. Methods for Expanding Access There are many methods for expanding access to patients in rural and underserved areas. Telehealth Airway Care The use of telehealth treatment has significantly expanded in recent years. With telehealth tools, hybrid care models combine in-person and virtual visits. This same technology also connects doctors, bringing together specialists and community clinicians. Regional Centers of Excellence Multidisciplinary airway centers have proven effective for helping patients access specialty care. Airway centers make it easier to streamline referrals in complex cases. These airway centers can serve larger geographic areas by setting up outreach clinics in surrounding communities. Collaborative Networks Partnerships and collaborations between physicians are key to ensuring that primary care providers in underserved areas have access to resources and information. Supporting Rural Physicians There are many ways to support rural physicians. Snot Force has committed to build networks for physicians, helping to ensure the dissemination of information across specialties and practice settings. We facilitate collaboration between disciplines to promote innovation in care for underserved communities. We're bringing doctors together to break down specialty care disparities and improve rural ENT access and information. Our research collaborative depends on many medical professionals to participate, and we're always looking for more physicians to join the force. To learn more, contact Snot Force today .
