This critical review of the AR literature has identified several strengths; providers can be confident that treatment decisions are supported by rigorous studies. However, there are also substantial gaps in the AR literature. These knowledge gaps should be viewed as opportunities for improvement, as often the things that we teach and the medicine that we practice are not based on the best quality evidence. This document aims to highlight the strengths and weaknesses of the AR literature to identify areas for future AR research and improved understanding.

We show a high percentage of CRS patients (28.6%) whose sinonasal mucopurulence has biofilm-forming capacity. Postsurgical patients had a high prevalence of biofilm-forming bacteria, a possible reflection of the severe nature of their disease. Additional studies are warranted.

The study provides further evidence that bacterial rhinosinusitis can involve bone at a distance from the site of primary infection, thereby suggesting that infectious agents may spread through bony structures in the pathogenesis of chronic rhinosinusitis.

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.

Our data indicate that functional endoscopic sinus surgery, combined with appropriate postoperative care, is effective at maintaining a significant improvement in the overall general health status of patients for at least 3 years after surgical intervention and that the overall scores return to a range of normative values for the general population.

Objectives: Adults with cystic fibrosis (CF) represent a challenging subset of patients with chronic rhinosinusitis (CRS). While data suggest that endoscopic sinus surgery (ESS) may benefit pediatric CF patients, there remains a paucity of data regarding the impact of endoscopic sinus surgery on adult CF patients with CRS. Our purpose was to evaluate objective and quality of life measures in adult CF patients with CRS following ESS. Study Design: Nested case-control study. Setting: Tertiary care center Methods: Twenty patients with CF were evaluated and matched to 20 controls without concomitant CF. Pre-operative computed tomography (CT) and pre-/post-operative endoscopic findings were recorded as objective measures. Changes in two disease-specific quality of life (QoL) instruments were also evaluated both pre- and post-operatively. Results: Mean post-operative follow-up was similar for cases and controls (13.1 ± 7.9 months vs. 14.0 ± 6.0 months, respectively). Pre-operative CT scores (16.9±4.5 vs. 10.9±5.9, p = 0.001) and endoscopy scores (9.3±5.8 vs. 5.7±4.6, p = 0.049) were significantly worse in CF patients. Post-operative endoscopy scores were significantly worse for CRS patient with CF (p=0.001), although the degree of improvement on endoscopy within each group was no different (p =0.071). Additionally, both groups experienced similar improvement in QoL after ESS (all p ≥ 0.134). Conclusions: While baseline measures of disease-severity are worse in the CF population, our data support objective and QoL improvements for adult patients with co-morbid CF comparable to patients without CF.

Using the questions from the RSDI, there is an improvement in scores of sexual function and sleep after surgery for patients with chronic rhinosinusitis. Further, more in-depth evaluations of these potential benefits are needed.
