AbstractThe American Academy of Otolaryngology–Head and Neck Surgery Foundation has published a supplement to this issue of Otolaryngology–Head and Neck Surgery featuring the updated “Clinical Practice Guideline: Adult Sinusitis”. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 14 developed recommendations address diagnostic accuracy for adult rhinosinusitis, the appropriate use of ancillary tests to confirm diagnosis and guide management (including radiography, nasal endoscopy, computed tomography, and testing for allergy and immune function), and the judicious use of systemic and topical therapy. Emphasis was also placed on identifying multiple chronic conditions that would modify management of rhinosinusitis, including asthma, cystic fibrosis, an immunocompromised state, and ciliary dyskinesia. An updated guideline is needed as a result of new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group.

The guideline update group represented the disciplines of otolaryngology–head and neck surgery, infectious disease, family medicine, allergy and immunology, advanced practice nursing, and a consumer advocate.Differences from Prior GuidelineThis clinical practice guideline is as an update, and replacement, for an earlier guideline published in 2015 by the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO‐HNSF).1 An update was planned for 5 years after the initial publication date and was further necessitated by new primary studies and systematic reviews that might suggest a need for modifying clinically important recommendations.2 Changes in content and methodology from the prior guideline include the following: New evidence from 14 guidelines, 194 systematic reviews, and 133 RCTs. Emphasis on patient education and counseling with new explanatory tables. Expanded action statement profiles to explicitly state quality improvement opportunities, confidence in the evidence, intentional vagueness, and differences of opinion. Enhanced external review process to include public comment and journal peer review. New algorithm to clarify decision making, watchful waiting, action statement relationships. Extension of watchful waiting (without antibiotic therapy) as an initial management strategy to all patients with uncomplicated acute bacterial rhinosinusitis (ABRS) regardless of severity, not just patients with “mild” illness (prior guideline). Clarified the recommended timeline for the diagnosis, conservative management and antibiotic treatment of ABRS. Change in recommendation to first‐line antibiotic therapy for ABRS amoxicillin, with or without clavulanate, from amoxicillin alone (prior guideline). Addition of aspirin exacerbated respiratory disease (AERD) as a chronic condition that modifies management of chronic rhinosinusitis (CRS). Three new key action statements on managing CRS that focus on the use of biologics (recommend against when patients do not have polyps and educate patients about them when they do) and a recommendation against the empiric use of antibiotics for CRS solely as a third‐party requirement for surgery or imaging.

The American Academy of Otolaryngology—Head and Neck Surgery Foundation (AAO‐HNSF) has published a supplement to this issue featuring the new Clinical Practice Guideline: Bell's Palsy. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 11 recommendations developed encourage accurate and efficient diagnosis and treatment and, when applicable, facilitate patient follow‐up to address the management of long‐term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. There are myriad treatment options for Bell's palsy; some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, there are numerous diagnostic tests available that are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have an unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy.

Objective Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mono‐neuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. Bell's palsy is a rapid unilateral facial nerve paresis (weakness) or paralysis (complete loss of movement) of unknown cause. The condition leads to the partial or complete inability to voluntarily move facial muscles on the affected side of the face. Although typically self‐limited, the facial paresis/paralysis that occurs in Bell's palsy may cause significant temporary oral incompetence and an inability to close the eyelid, leading to potential eye injury. Additional long‐term poor outcomes do occur and can be devastating to the patient. Treatments are generally designed to improve facial function and facilitate recovery. There are myriad treatment options for Bell's palsy, and some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, numerous diagnostic tests available are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. Purpose The primary purpose of this guideline is to improve the accuracy of diagnosis for Bell's palsy, to improve the quality of care and outcomes for patients with Bell's palsy, and to decrease harmful variations in the evaluation and management of Bell's palsy. This guideline addresses these needs by encouraging accurate and efficient diagnosis and treatment and, when applicable, facilitating patient follow‐up to address the management of long‐term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. The guideline is intended for all clinicians in any setting who are likely to diagnose and manage patients with Bell's palsy. The target population is inclusive of both adults and children presenting with Bell's palsy. Action Statements The development group made a strong recommendation that (a) clinicians should assess the patient using history and physical examination to exclude identifiable causes of facial paresis or paralysis in patients presenting with acute‐onset unilateral facial paresis or paralysis, (b) clinicians should prescribe oral steroids within 72 hours of symptom onset for Bell's palsy patients 16 years and older, (c) clinicians should not prescribe oral antiviral therapy alone for patients with new‐onset Bell's palsy, and (d) clinicians should implement eye protection for Bell's palsy patients with impaired eye closure. The panel made recommendations that (a) clinicians should not obtain routine laboratory testing in patients with new‐onset Bell's palsy, (b) clinicians should not routinely perform diagnostic imaging for patients with new‐onset Bell's palsy, (c) clinicians should not perform electrodiagnostic testing in Bell's palsy patients with incomplete facial paralysis, and (d) clinicians should reassess or refer to a facial nerve specialist those Bell's palsy patients with (1) new or worsening neurologic findings at any point, (2) ocular symptoms developing at any point, or (3) incomplete facial recovery 3 months after initial symptom onset. The development group provided the following options : (a) clinicians may offer oral antiviral therapy in addition to oral steroids within 72 hours of symptom onset for patients with Bell's palsy, and (b) clinicians may offer electrodiagnostic testing to Bell's palsy patients with complete facial paralysis. The development group offered the following no recommendations : (a) no recommendation can be made regarding surgical decompression for patients with Bell's palsy, (b) no recommendation can be made regarding the effect of acupuncture in patients with Bell's palsy, and (c) no recommendation can be made regarding the effect of physical therapy in patients with Bell's palsy.
