Chronic rhinosinusitis (CRS) affects more than one in ten adults worldwide and drives over four million ambulatory visits annually in the United States alone. Patients with CRS endure persistent nasal congestion, facial pain, discolored drainage, and a diminished sense of smell for 12 weeks or longer. Beyond nasal symptoms, CRS can profoundly impair sleep quality, cognitive function, and emotional well-being. Many sufferers experience “brain fog,” depression, anxiety, and fatigue that cascade into missed workdays, strained relationships, and reduced quality of life. Recognizing the broad systemic effects of this once-underappreciated disease, the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) convened an expert panel to develop evidence-based recommendations for surgical intervention.
Scope and Purpose of the Guideline
The newly published Clinical Practice Guideline (CPG): Surgical Management of Chronic Rhinosinusitis outlines 11 key action statements to guide clinicians and patients through the decision-making process for sinus surgery. Chaired by Dr. Jennifer J. Shin of the University of California, San Diego, the Guideline Development Group comprised 18 multidisciplinary experts in rhinology, comprehensive otolaryngology, allergy, advanced practice, and patient advocacy. Their mission was to translate the latest systematic reviews, meta-analyses, randomized controlled trials, and observational research into practical recommendations for preoperative assessment, intraoperative techniques, and postoperative care.
Key Action Statements for Surgical Management
Preoperative Evaluation and Patient Selection
Action Statement 1: Confirm Diagnosis and Medical Therapy Failure. CRS should be diagnosed based on the presence of at least two cardinal symptoms—nasal obstruction, facial pain/pressure, thick or discolored drainage, and smell loss—persisting for a minimum of 12 weeks, together with objective evidence of sinus inflammation on endoscopy or imaging. Before considering surgery, clinicians must ensure that patients have undergone an adequate trial of maximal medical therapy, including intranasal corticosteroids, saline irrigation, and, where indicated, antibiotics or systemic steroids.
Action Statement 2: Assess Comorbidities and Optimize Health. Surgical candidates should be screened for comorbid conditions that may influence outcomes, such as asthma, allergic rhinitis, cystic fibrosis, immune deficiencies, and aspirin-exacerbated respiratory disease. Preoperative optimization—control of allergy triggers, asthma inhaler adherence, and nutritional status—can reduce postoperative complications and improve symptom relief.
Action Statement 3: Engage in Shared Decision-Making. Physicians should discuss the risks, benefits, and alternatives to surgery in clear, patient-centered language. Decision aids and consent forms must outline expected outcomes, potential complications (e.g., bleeding, infection, cerebrospinal fluid leak), and the likelihood of symptom improvement. Involving patients in goal-setting fosters realistic expectations and greater satisfaction with care.
Intraoperative Techniques and Surgical Extent
Action Statement 4: Tailor Surgical Approach to Disease Extent. Endoscopic sinus surgery (ESS) remains the cornerstone of surgical management. The extent of ESS—ranging from targeted removal of obstructing polyps or mucosal disease to more extensive opening of all diseased sinuses—should reflect preoperative imaging findings and intraoperative endoscopic assessment. Localized disease may benefit from limited sphenoid or frontal sinusotomies, whereas diffuse polyposis often requires full-house ESS.
Action Statement 5: Utilize Image Guidance Selectively. In cases of complex anatomy, revision surgery, or high-risk regions such as the frontal recess or sphenoid roof, intraoperative image guidance systems enhance surgical precision and safety. However, routine use in uncomplicated primary surgeries is not mandated unless anatomical landmarks are obscured by disease.
Action Statement 6: Consider Adjunctive Procedures. For patients with CRS and concomitant obstruction of the nasal valve, septal deviation, or turbinate hypertrophy, concurrent techniques—septoplasty, turbinate reduction, or nasal valve repair—can optimize nasal airflow and ameliorate postoperative discomfort. The Guideline recommends individualized consideration of these adjuncts to maximize surgical benefit.
Postoperative Care and Long-Term Management
Action Statement 7: Implement Structured Postoperative Protocols. Effective postoperative care begins immediately after ESS. Saline irrigations should commence within 24–48 hours to clear crusts and promote mucosal healing. Regular endoscopic debridements—typically at one and two weeks—help prevent synechiae formation and identify early complications. A standardized regimen of topical corticosteroid irrigations or sprays for at least six weeks can further reduce polyp recurrence.
Action Statement 8: Monitor and Treat Complications Early. Clinicians should educate patients on warning signs of postoperative complications, including persistent bleeding, severe pain, or vision changes. Prompt evaluation and intervention—packing removal, antibiotic therapy, or surgical revision—can mitigate adverse outcomes.
Action Statement 9: Define Criteria for Revision Surgery. Despite optimal initial intervention, up to 10–20% of patients may experience symptom recurrence necessitating revision ESS. Revision should be considered when patients demonstrate refractory symptoms, evidence of persistent disease on endoscopy or imaging, and failure of additional medical therapy. Revision surgeries warrant careful planning and, often, image guidance due to distorted anatomy.
Enhancing Patient-Centered Outcomes
Action Statement 10: Measure Quality of Life and Patient-Reported Outcomes. Beyond objective measures, the Guideline underscores the importance of validated instruments—such as the Sino-Nasal Outcome Test (SNOT-22) and generic health surveys—to track symptom burden, functional status, and psychosocial well-being. Routine collection of patient-reported outcomes can inform individualized care plans and facilitate research into surgical efficacy.
Action Statement 11: Address Health Disparities and Access to Care. CRS disproportionately impacts socioeconomically disadvantaged populations, who face barriers to specialty consultations and surgery. The Guideline calls on health systems to develop pathways—telemedicine triage, centralized referral hubs, and sliding-scale fee structures—to ensure equitable access to both medical and surgical management.
Implications for Clinical Practice and Health Systems
Strengthening Care Pathways
The Guidelines provide a structured framework for otolaryngologists, primary care providers, allergists, and allied health professionals to collaborate on the continuum of CRS care. By delineating criteria for surgical referral, standardizing perioperative protocols, and emphasizing patient education, health systems can reduce unwarranted variation in practice and improve efficiency. Integrated care models—combining outpatient medical management with streamlined surgical scheduling—may reduce wait times and optimize resource utilization.
Driving Future Research
Although the Guidelines distill current evidence, several areas warrant further study. Head-to-head trials comparing limited versus extended ESS across various CRS phenotypes, long-term comparative effectiveness of topical corticosteroid formulations, and the role of biologic agents in surgical candidates remain evolving fields. Establishing national CRS registries and embedding standardized outcome measures will accelerate high-quality research and iterative guideline updates.
Enhancing Patient Engagement and Education
Patients often underestimate the systemic impact of CRS and view it as a minor nuisance. The Guidelines advocate for clear educational materials—multilingual brochures, digital decision aids, and support group networks—to raise awareness of CRS as a chronic disease warranting comprehensive management. Empowering patients to track their symptoms through mobile health apps and engage in shared decision-making can improve adherence to both medical and surgical care plans.
Conclusion
The AAO-HNSF Clinical Practice Guideline on the Surgical Management of Chronic Rhinosinusitis represents a milestone in otolaryngology, providing evidence-based, patient-centered recommendations for the millions affected by CRS. By harmonizing diagnostic criteria, optimizing patient selection, refining surgical techniques, and standardizing postoperative care, the Guideline aims to elevate the quality and consistency of CRS surgical care. Implementation of these key action statements—across academic centers, community practices, and health systems—promises to reduce symptom burden, enhance quality of life, and deliver long-term relief for a condition that extends far beyond nasal congestion. As CRS research advances and new therapies emerge, ongoing multidisciplinary collaboration and registry-based outcomes tracking will be essential to refine these recommendations and ensure that patients receive the safest, most effective surgical care available.
