Patient perspectives on recall period and response options in patient-reported outcome measures for chronic rhinosinusitis symptomatology: An international multi-centered study.

BACKGROUND: Existing patient-reported outcome measures (PROMs) for chronic rhinosinusitis (CRS) use a variety of recall periods and response scales to assess CRS symptom burden. Global perspectives of CRS patients regarding optimal recall periods and response scales for CRS PROMs are unknown. METHODS: This was a multi-center, cross-sectional study recruiting 461 CRS patients from sites across the United States, Saudi Arabia, New Zealand, and Austria. Participants chose which CRS symptom recall period (1 day, 2 weeks, 1 month, >1 month) was most reflective of their current disease state and upon which to best base treatment recommendations (including surgery). Participants also chose which of six response scales (one visual analogue scale and five Likert scales ranging from four to eight items) was easiest to use, understand, and preferred. RESULTS: A plurality of participants (40.0%) felt their CRS symptoms' current state was best reflected by a 1-month recall period. However, most patients (56.9%) preferred treatment recommendations to be determined by symptoms experienced over a >1 month period. The four- and five-item Likert scales were the easiest to understand (26.0% and 25.4%, respectively) and use (23.4% and 26.7%, respectively). The five-item (26.4% rating it most preferred and 70.9% rating it preferred) and four-item Likert (22.3% rating it most preferred and 56.4% rating it preferred) response scales were most preferred. CONCLUSION: Future PROMs for CRS should consider assessment of symptoms over a 1-month period and use a four- or five-item Likert response scale to reflect global patient preferences. These findings also inform interpretation of current CRS PROMs.

Minimal Radiographic Mucosal Thickness or Opacification Criterion for Sinus-Specific Endoscopic Sinus Surgery for Chronic Rhinosinusitis.

OBJECTIVE: Primary chronic rhinosinusitis (CRS) is typically a diffuse process and the extent of endoscopic sinus surgery (ESS) performed for medically recalcitrant CRS is impacted by many factors. However, some third-party payors have implemented policies to authorize coverage for ESS in a sinus-by-sinus manner based on a minimal measurement of millimeters of mucosal thickening or sinus opacification in the corresponding sinus that is being surgically addressed. Our objective was to determine whether such policies are based on scientific evidence that in patients with medically recalcitrant CRS, a minimum measurement of mucosal thickening or sinus opacification is a predictor of CRS in that sinus or improved outcomes after ESS on a sinus-by-sinus basis. DATA SOURCES: Medline, Embase, Scopus, and Web of Science databases, from inception through May 2022. REVIEW METHODS: A systematic review was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. RESULTS: We identified 6070 abstracts which were screened and from which 112 studies ultimately underwent a full-text review. From these studies, we found that none investigated (or provided evidence of) whether any minimal degree of radiographic mucosal thickening or sinus opacification predicted CRS or better outcomes after ESS in a sinus-specific manner. CONCLUSION: We were unable to find evidence supporting a minimum millimeter measurement of mucosal thickening or sinus opacification as predictors of CRS or better post-ESS outcomes in a sinus-specific manner in patients with medically recalcitrant CRS. The extent of ESS for CRS should be determined through personalized medical decision-making that considers all patient-specific factors.

Ergonomics in Otolaryngologic Surgery: A State of the Art Review.

OBJECTIVE: Otolaryngology is a surgical field with a high degree of ergonomic risk. The use of head-mounted lighting, loupe magnification, endoscopes, and microscopes is inherent to the field, coupled with repetitive fine motor movements in a constrained anatomic field as well as static, ergonomically unfavorable postures. We seek to review the otolaryngologic literature on ergonomics, including prevalence, severity, and interventions in decreasing work-related musculoskeletal pain. DATA SOURCES: Data were derived from clinical peer-reviewed primary literature as well as information provided by residency programs and presented at national and international meetings. REVIEW METHODS: A comprehensive review was performed by 3 independent reviewers utilizing an electronic database literature search through PubMed, Embase, and Cochrane Library. Search terms included combinations and variations of the following concepts: ergonomics, surgery, otolaryngology, work related musculoskeletal disorders, chronic cervical pain, musculoskeletal, posture, surveys, microsurgery, endoscopic surgery. Strict objective criteria for inclusion were not used due to the inherent heterogeneity in articles and lack of rigorous empirical evidence. CONCLUSIONS: Chronic musculoskeletal pain is prevalent among otolaryngologic surgeons, with many procedures producing high ergonomic risk. Most studies evaluating interventions to decrease ergonomic risks demonstrate promising results, but standardization in methods and outcome reporting is needed. IMPLICATIONS FOR PRACTICE: Literature shows that musculoskeletal pain begins in training, and there is a paucity of information related to ergonomic risk in otolaryngology residency curriculums. Work-related musculoskeletal disorders related to poor workplace ergonomics have the potential to limit career longevity and lead to physician burnout. Interventions to mitigate this risk are effective and tend to be well received by physicians.

Acute exacerbations of chronic rhinosinusitis: The current state of knowledge.

Objectives: Acute exacerbations of chronic rhinosinusitis (AECRS) are distinct from baseline symptomatology related to chronic rhinosinusitis (CRS). In this review, we seek to examine the literature on AECRS to synthesize the definition, epidemiology, pathophysiology, treatment, and impact of AECRS on CRS patients. Methods: A comprehensive narrative review of the scientific literature, identified by searching PubMed from inception through April 2022, was performed. Results: AECRS is defined in consensus guidelines as a worsening of chronic sinus disease symptomatology, with a return to baseline, typically after intervention with systemic antibiotics and/or corticosteroids. The working definition used across the literature, however, is broad and heterogeneous. The pathophysiology of AECRS is incompletely understood but is hypothesized to include an interplay of environmental and patient-specific factors. AECRS have been found to have a negative impact on quality-of-life measures, independent of baseline CRS symptomatology, and impact how patients and physicians view overall disease control. Treatment for AECRS includes oral antibiotics and systemic corticosteroids, although their efficacy for AECRS is unclear. Appropriate use of medical and surgical treatment for CRS can reduce the frequency of AECRS. Conclusions: AECRS are a distinct entity in CRS patients and should be independently assessed when evaluating patients for CRS control. The efficacy of systemic medication usage for AECRS is currently unclear, but appropriate medical management of baseline CRS can reduce the frequency of AECRS. More research is needed to further understand this phenomenon, including a more precise and prospective definition, defined epidemiology, and how to appropriately treat. Level of Evidence: 5.

Obesity Is Not Associated With Postoperative Complications After Vestibular Schwannoma Surgery in a Large Single Institution Series.

OBJECTIVE: Determine whether elevated body mass index (BMI) is associated with postoperative complications after vestibular schwannoma (VS) surgery. STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center. PATIENTS: Two hundred six patients undergoing surgery for VS between 2010 and 2017, grouped into obese and nonobese patients. INTERVENTION: Surgery for VS resection. MAIN OUTCOME MEASURES: Postoperative facial nerve outcomes, length of hospital stay, presence of postoperative cerebrospinal fluid leak, 30-day readmission, return to the operating room, wound complications, cardiovascular and thromboembolic complications. RESULTS: After excluding 1 patient for missing BMI, our cohort included 205 patients. Seventy-nine patients (38.5%) were obese (mean BMI 36.2 kg/m, range 30-55.1) and the remaining 126 (61.5%) were nonobese (mean BMI 25.0, range 18.8-29.8 kg/m). Compared with nonobese patients, obesity was not associated with postoperative cerebrospinal fluid leak (OR 1.1, 95% CI 0.93-1.1), length of hospital stay (OR 0.98, 95% CI 0.65-1.47), 30-day readmission rates (1.04, 95% CI 0.95-1.14), return to operating room (OR 1.05, 95% CI 0.98-1.11), or other wound-related complications (OR 0.99, 95% CI 0.94-1.04). CONCLUSION: In this cohort, elevated BMI was not associated with an increased risk for postoperative complications after VS surgery. Our findings may mitigate concerns associated with surgical management of VS in obese patients.

Cerebrospinal Fluid Leak Rate after Vestibular Schwannoma Surgery via Middle Cranial Fossa Approach.

Objective Evaluate the cerebrospinal fluid (CSF) leak rate after the middle cranial fossa (MCF) approach to vestibular schwannoma (VS) resection. Design Retrospective case series. Setting Quaternary referral academic center. Participants Of 161 patients undergoing the MCF approach for a variety of skull base pathologies, 66 patients underwent this approach for VS resection between 2007 and 2017. Main Outcome Measure Postoperative CSF leak rate. Results There were two instances of postoperative CSF leak (3.0%). Age, gender, and BMI were not significantly associated with CSF leak. In the two cases with CSF leakage, tumors were isolated to the internal auditory canal (IAC) and both underwent gross total resection. Both CSF leaks were successfully treated with lumbar drain diversion. For the 64 cases that did not have a CSF leak, 51 were isolated to the IAC, 1 was located only in the cerebellopontine angle (CPA), and 12 were located in both the IAC and CPA. 62 patients underwent gross total resection and 2 underwent near-total resection. Mean maximal tumor diameter in the CSF leak group was 4.5 mm (range: 3-6 mm) versus 10.2 mm (range: 3-19 mm) in patients with no CSF leak ( p = 0.03). Conclusions The MCF approach for VS resection is a valuable technique that allows for hearing preservation and total tumor resection and can be performed with a low CSF leakage rate. This rate of CSF leak is less than the reported rates in the literature in regard to both translabyrinthine and retrosigmoid approaches.

Canal reconstruction mastoidectomy: Outcomes comparison following primary versus secondary surgery.

OBJECTIVES/HYPOTHESIS: Compare surgical and audiometric outcomes following canal wall reconstruction (CWR) tympanomastoidectomy used as a primary versus secondary approach for treating cholesteatoma. STUDY DESIGN: Retrospective. METHODS: Patients treated for primary/secondary cholesteatoma from 2006 to 2017 via CWR were included if they had preoperative/postoperative audiograms, detailed operative note(s), and >12 months' follow-up. Patients were stratified by previous surgical history into two groups: primary CWR group (PG) and secondary CWR group (SG). Surgical outcomes measured were prevalence of recidivistic cholesteatoma, canal cholesteatoma, revision rate, and canal wall down (CWD) conversion rates. Secondary outcomes were prevalence of infection, external canal adhesions/stenoses, and retractions. Audiometric outcomes included change in pure-tone average and air-bone gap. RESULTS: We stratified 45 patients/ears into the PG and 26 into the SG. The groups did not significantly differ in age, sex, or smoking status. Overall, median follow-up was 35 months. SG patients had higher rates of cholesteatoma detected at staged surgery than did PG patients (P = .04). However, these patients exhibited lower rates of open revision surgery (4% vs.13%) and a significant improvement in air-bone gap (P = .004). Three PG patients (7%) required conversion to CWD versus zero SG patients. Secondary outcomes were similar. Patients who underwent delayed staging >12 months from CWR had increased rates of recidivism and canal adhesion/stenosis. CONCLUSIONS: CWR was effective for treating cholesteatoma as both a primary and secondary surgical approach. SG patients experienced higher rates of recidivism and secondary canal cholesteatoma. PG patients had higher rates of revision surgery. Staging of ears undergoing CWR is important regardless of prior surgical history. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:2580-2587, 2019.

Relative Preservation of Superior Semicircular Canal Architecture in CHARGE Syndrome.

OBJECTIVES: (1) Describe common patterns of semicircular canal (SCC) anomalies in CHARGE syndrome (CS) and (2) recognize that in CS, the architecture of the superior SCC may be relatively preserved. STUDY DESIGN: This is a retrospective review of temporal bone imaging studies. SETTING: Quaternary care center. SUBJECTS AND METHODS: A sample of 37 patients with CS. All subjects met clinical diagnostic criteria for CS. The presence/absence of anomalies of the middle ear, mastoid, temporal bone venous anatomy, inner ear, and internal auditory canal was recorded. Anomalies of each SCC were considered separately and by severity (normal, dysplasia, aplasia). RESULTS: Thirty-seven subjects (74 temporal bones) were reviewed. Thirty-four (92.0%) patients demonstrated bilateral SCC anomalies. Three (8.0%) had normal SCCs. In patients with SCC anomalies, all canals demonstrated bilateral abnormalities. Thirty-two (86.5%) patients had bilateral horizontal SCC aplasia. These 32 patients also demonstrated posterior SCC aplasia in at least 1 ear. Of 74 temporal bones, 37 (50.0%) had superior SCC dysplasia. All dysplastic superior SCCs showed preservation of the anterior limb. Complete superior SCC aplasia was found in 28 (37.8%) temporal bones. CONCLUSION: SCC anomalies occur with high frequency in CS. Complete absence of the horizontal and posterior canals is typical and usually bilateral. By contrast, the superior SCC often demonstrates relative preservation of the anterior limb.

Impact of Motor-Evoked Potential Monitoring on Facial Nerve Outcomes after Vestibular Schwannoma Resection.

OBJECTIVES:: Assess the utility of intraoperative transcranial facial motor-evoked potential (FMEP) monitoring in predicting and improving facial function after vestibular schwannoma (VS) resection. STUDY DESIGN:: Retrospective chart review. METHODS:: Data were obtained from 82 consecutive VS resections meeting inclusion criteria. Sixty-two cases were performed without FMEP and 20 with FMEP. Degradation of FMEP response was defined as a final-to-baseline amplitude ratio of 0.5 or less. House-Brackmann (HB) grade was assessed preoperatively, postoperatively, at follow-up assessments, and it was compared between pre- and post-FMEP cohorts. Positive predictive value (PPV) and negative predictive value (NPV), sensitivity, and specificity of FMEP degradation in predicting facial weakness were calculated. RESULTS:: In the pre-FMEP group, at length of follow-up (LOF) ⩾9 months, 83.9% (52/62) of patients exhibited HB 1-2 outcome. In the post-FMEP cohort, 75.0% (15/20) exhibited HB 1-2 function at LOF ⩾9 months. There was no difference in rates of HB 1-2 outcomes between groups in the immediate postoperative period ( P = .35) or at long-term follow-up ( P = 1.0). With respect to predicting immediate postoperative facial function, FMEP demonstrated high specificity (88.9%) and moderate sensitivity (54.5%). The PPV and NPV for immediate postoperative facial function were 85.7% and 61.5%, respectively. With respect to long-term (⩾9 months LOF) facial function, intraoperative FMEP was moderately sensitive (71.4%) and highly specific (84.6%); PPV was moderate (71.4%), and NPV was high (84.6%). CONCLUSIONS:: Intraoperative FMEP is highly specific and moderately sensitive in predicting postoperative facial function for patients undergoing VS resection, but its use may not be associated with improved facial nerve outcomes. LEVEL OF EVIDENCE:: 4.

Two Consecutive Cases of Persistent Stapedial Artery Managed With a Carbon Dioxide Laser.

OBJECTIVE: (1) Discuss the presentation and management of persistent stapedial artery (PSA) discovered incidentally during cholesteatoma surgery. (2) Review use of carbon dioxide (CO2) laser for treatment of PSA in the setting of chronic ear disease. PATIENTS: Two consecutive patients with PSA and primary acquired cholesteatoma. INTERVENTION(S): Tympanomastoidectomy using a canal wall reconstruction technique. MAIN OUTCOME MEASURE(S): Surgical healing, collateral damage to surrounding anatomy, and postoperative hearing. RESULTS: Persistent stapedial artery was detected incidentally in 2 patients, manifesting with heavy pulsatile bleeding arising during dissection of mesotympanic cholesteatoma. Preoperative computed tomography scans demonstrated absent foramen spinosum but no other aberrant vascular anatomy. Using CO2 laser, the PSAs were ablated and controlled, allowing complete resection of cholesteatoma and successful completion of the procedure. In both patients, surrounding anatomical structures suffered no iatrogenic injury. Postoperatively, no significant complications occurred. To date, neither patient has demonstrated evidence of recidivistic cholesteatoma. CONCLUSIONS: A CO2 laser can be useful for managing a PSA in the setting of chronic ear disease.
