Objectives (1) Describe national patterns of chronic rhinosinusitis (CRS) care across academic and community practices. (2) Determine the prevalence of comorbid disorders in CRS patients, including nasal polyposis, allergic rhinitis, asthma, and cystic fibrosis. (3) Identify demographic, clinical, and practice type factors associated with endoscopic sinus surgery (ESS). Study Design Multisite cross-sectional study. Setting Otolaryngology’s national research network CHEER (Creating Healthcare Excellence through Education and Research). Subjects and Methods A total of 17,828 adult patients with CRS were identified, of which 10,434 were seen at community practices (59%, n = 8 sites) and 7394 at academic practices (41%, n = 10 sites). Multivariate logistic regression was used to evaluate the association between demographic, practice type, and clinical factors and the odds of a patient undergoing ESS. Results The average age was 50.4 years; 59.5% of patients were female; and 88.3% were Caucasian. The prevalence of comorbid diseases was as follows: allergic rhinitis (35.1%), nasal polyposis (13.3%), asthma (4.4%), and cystic fibrosis (0.2%). In addition, 24.8% of patients at academic centers underwent ESS, as compared with 12.3% at community sites. In multivariate analyses, nasal polyposis (odds ratio [OR], 4.28), cystic fibrosis (OR, 2.42), and academic site type (OR, 1.86) were associated with ESS (P < .001), while adjusting for other factors. Conclusions We describe practice patterns of CRS care, as well as demographic and clinical factors associated with ESS. This is the first study of practice patterns in CRS utilizing the CHEER network and may be used to guide future research.

Objectives (1) Compare postoperative bleeding in the CHEER network (Creating Healthcare Excellence through Education and Research) among age groups, diagnoses, and practice types. (2) Report the incidence of bleeding by individual CHEER practice site based on practice guidelines. Study Design Retrospective data collection database review of the CHEER network based on ICD-9 and CPT codes related to tonsillectomy patients. Setting Multisite practice–based network. Subjects and Methods A total of 8347 subjects underwent tonsillectomy as determined by procedure code within the retrospective data collection database, and 107 had postoperative hemorrhage. These subjects had demographic information and related diagnoses based on the CPT and ICD-9 codes collected. Postoperative ICD-9 and CPT codes were used to identify patients who also had postoperative bleed. Variables included age (<12 vs ≥12 years), diagnoses (infectious vs noninfectious), and practice type (community vs academic). Statistical analysis included multivariate logistic regression variables predictive of postoperative bleeding, with P < .05 considered significant. Results Thirteen sites contributed data to the study (7 academic, 6 community). There was postoperative bleeding for an overall bleed rate of 1.3%. Patients ≥12 years old had a significantly increased bleed rate when compared with the younger group (odds ratio, 5.98; 95% confidence interval: 3.79-9.44; P < .0001). There was no significant difference in bleed rates when practices or diagnoses were compared. Conclusion A site descriptor database built to expedite clinical research can be used for practice assessment and quality improvement. These data were also useful to identify patient risk factors for posttonsillectomy bleed.

Objectives (1) Describe thyroid-related diagnoses and procedures in Creating Healthcare Excellence through Education and Research (CHEER) across academic and community sites. (2) Compare management of malignant thyroid disease across these sites. (3) Provide practice-based data related to flexible laryngoscopy vocal fold assessment before and after thyroid surgery based on the American Academy of Otolaryngology—Head and Neck Surgery Foundation’s clinical practice guidelines. Study Design Review of retrospective data collection (RDC) database of the CHEER network using ICD-9 and CPT codes related to thyroid conditions. Setting Multisite practice-based network. Subjects and Methods There were 3807 thyroid patients (1392 malignant, 2415 benign) with 10,160 unique visits identified from 1 year of patient data in the RDC. Analysis was performed for identified cohort of patients using demographics, site characteristics, and diagnostic and procedural distribution. Results Mean number of patients with thyroid disease per site was 238 (range, 23-715). In community practices, 19% of patients with thyroid disease had cancer versus 45% in the academic setting (P < .001). While academic sites manage more cancer patients, community sites are also surgically treating thyroid cancer and performed more procedures per cancer patient (4.2 vs 3.5, P < .001). Vocal fold function was assessed by flexible laryngoscopy in 34.0% of preoperative patients and in 3.7% postoperatively. Conclusion This is the first overview of malignant and benign thyroid disease through CHEER. It shows how the RDC can be used alone and with national guidelines to inform of clinical practice patterns in academic and community sites. This demonstrates the potential for future thyroid-related studies utilizing the otolaryngology–head and neck surgery practice-based research network.

Radiographic characterization of the retroantral ethmoid cell

Nikita Chapurin; Adam Honeybrook; Sean J. Johnson; Cynthia Wang; David W. Jang

The retroantral ethmoid cell (RAEC) is defined as a posterior ethmoid cell that pneumatizes inferolaterally behind the posterior wall of the maxillary sinus. The RAEC can present a challenge to otolaryngologists during endoscopic ethmoidectomy due to its concealed location. It is also encountered during the endoscopic transpterygoid approach to the skull base, which requires dissection behind the posterior wall of the maxillary sinus. Because the RAEC is not described in the literature, this study aims to better characterize this anatomic variant.

Epiglottic cyst causing dysphagia and impending airway obstruction.

Alissa M. Collins; Nikita Chapurin; Walter T. Lee

Laryngeal cysts are relatively rare benign lesions of the larynx. Congenital cysts can cause neonatal respiratory distress and death, but airway obstruction due to acquired cysts in adults is rare. We present a case report of 51-year-old male with dysphagia who was found to have a mobile pedunculated epiglottic cyst that intermittently caused partial obstruction of the laryngeal inlet. Patient was taken to operating room and following transoral fiberoptic intubation, endoscopic excision of this cyst was accomplished. Patients postoperative course was uneventful.

Obtaining postoperative images of maxillofacial fractures does not affect the clinical management of asymptomatic patients; however, few studies have evaluated the role of postoperative imaging in the context of orbital floor fractures. In this study, we evaluate current practice techniques and the role of postoperative imaging in the management of orbital floor fractures in isolation and with concomitant facial fractures. Retrospective review of patients who underwent open reduction and internal fixation of orbital floor fractures between 2005 and 2015 at a single medical institution. Operative and perioperative records were reviewed to characterize postoperative imaging as routine or as indicated by concerning clinical symptoms, and to correlate clinical outcomes to postoperative imaging patterns across all identified orbital floor fractures. A total of 139 patients underwent open reduction and internal fixation of orbital floor fractures. Of these, 75 (54%) had zygomaticomaxillary (ZMC) involvement. The remaining 64 (46%) were isolated orbital floor fractures. Overall, 54 (39%) patients underwent postoperative imaging. Of these, 38 (70%) had postoperative imaging in the absence of concerning clinical symptoms. There was no observed difference in complication rates in those who underwent postoperative imaging, and those who did not. Patients with orbital + ZMC fractures underwent a significantly higher number of postoperative imaging studies (p < 0.001); however, there was no observed difference in complications between isolated orbital and orbital + ZMC fractures. Routine postoperative imaging is not warranted in the absence of persistent clinical symptoms following open reduction and internal fixation of orbital floor fractures.

Adam Honeybrook; Aniruddha Patki; Nikita Chapurin; Charles R. Woodard

The aim of this article is to determine hearing and mortality outcomes following temporal bone fractures. Retrospective chart review was performed of 152 patients diagnosed with a temporal bone fracture presenting to the emergency room at a tertiary care referral center over a 10-year period. Utilizing Patients’ previously obtained temporal bone computed tomographic scans and audiograms, fractures were classified based on several classification schemes. Correlations between fracture patterns, mortality, and hearing outcomes were analyzed using χ2 tests. Ossicular chain disruption was seen in 11.8% of patients, and otic capsule violation was seen in 5.9%; 22.7% of patients presented for audiologic follow-up. Seventeen patients with conductive hearing loss had air–bone gaps of 26 ± 7.5 dB (500 Hz), 27 ± 6.8 dB (1,000 Hz), 18 ± 6.2 dB (2,000 Hz), and 32 ± 7.7 dB (4,000 Hz). Two cases of profound sensorineural hearing loss were associated with otic capsule violation. No fracture classification scheme was predictive of hearing loss, although longitudinal fractures were statistically associated with ossicular chain disruption (p < 0.01). Temporal bone fractures in patients older than 60 years carried a relative risk of death of 3.15 compared with those younger than 60 years. The average magnitude of conductive hearing loss resulting from temporal bone fracture ranged from 18 to 32 dB in this cohort. Classification of fracture type was not predictive of hearing loss, despite the statistical association between ossicular chain disruption and longitudinal fractures. This finding may be due to the low follow-up rates of this patient population. Physicians should make a concerted effort to ensure that audiological monitoring is executed to prevent and manage long-term hearing impairment.
