AbstractObjectivesThe study aimed to extract online comments of otolaryngologists in the 20 most populated cities in the United States from healthgrades.com, develop and validate a natural language processing (NLP) logistic regression algorithm for automated text classification of reviews into 10 categories, and compare 1‐ and 5‐star reviews in directly‐physician‐related and non‐physician‐related categories.Methods1977 1‐star and 12,682 5‐star reviews were collected. The primary investigator manually categorized a training dataset of 324 1‐star and 909 5‐star reviews, while a validation subset of 100 5‐star and 50 1‐star reviews underwent dual manual categorization. Using scikit‐learn, an NLP algorithm was trained and validated on the subsets, with F1 scores evaluating text classification accuracy against manual categorization. The algorithm was then applied to the entire dataset with comparison of review categorization according to 1‐ and 5‐star reviews.ResultsF1 scores for NLP validation ranged between 0.71 and 0.97. Significant associations emerged between 1‐star reviews and treatment plan, accessibility, wait time, office scheduling, billing, and facilities. 5‐star reviews were associated with surgery/procedure, bedside manner, and staff/mid‐levels.ConclusionThe study successfully validated an NLP text classification system for categorizing online physician reviews. Positive reviews were found to have an association with directly‐physician related context. 1‐star reviews were related to treatment plan, accessibility, wait time, office scheduling, billing, and facilities. This method of text classification effectively discerned the nuances of human‐written text, providing valuable insights into online healthcare feedback that is scalable.Level of evidence: Level 3

AbstractThe study objective was to compare the length of stay (LOS) and the proportion of one-night admissions before and after the implementation of an endocrine monitoring protocol following endoscopic transsphenoidal surgery (ETSS) for pituitary adenoma.Patients who underwent transsphenoidal pituitary adenoma resection between July 1, 2018, and September 9, 2022, were identified, and divided into two cohorts before and after the implementation of the monitoring protocol. The overall LOS and number of nights of admission were recorded. Readmission within 30 days after surgery was also recorded. The number of outpatient laboratory tests performed and the time to the first test were also noted.Thirty patients were identified in the preprotocol group and 60 in the postprotocol group. The average admission length in the preprotocol group was significantly longer than the average admission length in the postprotocol group (2.4 vs. 1.7 days, p = 0.004). The percentage of one-night admissions increased from 13 to 57% (p < 0.001). There were no significant differences in readmission rates between the two groups (p = 0.681). The number of laboratory encounters increased from a mean of 1.38 to 2.40 (p = 0.030), while the time to the first test decreased from a mean of 3.43 to 2.36 days (p = 0.049).Patients admitted after ETSS for pituitary adenoma had shorter hospital stay and greater proportion of one-night admission with the implementation of an endocrine monitoring protocol. The all-cause readmission rate was not statistically different between the two groups. Through aggressive outpatient laboratory monitoring, one-night admission for ETSS may be feasible.

Although technical causes of endoscopic sinus surgery (ESS) failure have long been reported, we were curious about the quality of contemporary sinus surgery. The electronic health database of Mayo Clinic, Arizona was scrutinized to identify adult patients with diffuse chronic rhinosinusitis (CRS) who underwent revision ESS between January 2019 and September 2023 with a history of bilateral full-house ESS. Anatomical features on preoperative radiology and intraoperative endoscopy were cataloged: residual uncinate tissue, maxillary antrostomy with a non-incorporated natural os, residual ethmoidal septations (three septations > 3 mm), and inadequate sphenoid osteotomy (os size < 6 mm). Sixty-nine subjects were identified. A deviated nasal septum was present in 53.6%. Residual uncinate tissue was noted in 50.7% of patients associated with missed natural maxillary os in 39.13% of antrostomies. An inadequate os diameter was noted in 63.8% of sphenoidotomies. Significant residual septations were seen in posterior ethmoidal cells in 66.7% and anterior ethmoidal cells in 62.3% of patients. Residual frontoethmoidal cells were noted in 72.4% of patients. Although the extent of ESS must be individualized, a high prevalence of features reflecting suboptimal surgery that could limit the success of ESS was identified. These findings merit further consideration for focused training during residency and continuous professional development activities.

Abstract Objective To describe and illustrate septal perforation shape through the documentation and analysis of length and height measurements. A secondary objective is to correlate perforation size to surgical and nonsurgical etiologies. Stuy Design Retrospective case series. Setting Tertiary academic medical center. Methods Length and height of consecutively treated perforations over a 3‐year period were measured directly or through computed tomography. Mean differences in length and height measurements were compared and regression analysis used to determine perforation shape and the effect of etiology on perforation size. Perforations were classified by length into small (1‐5 mm), medium (6‐15 mm), and large (>15 mm) and correlated to shape and etiology. Results One hundred twenty‐four patients (mean age 50.4 years, 60.5% female) met study inclusion criteria. Height was less than length in 93% of perforations 5 mm or greater in length. Mean perforation height was significantly less than length for medium and large perforations ( P < .001). Mean length and height measurements of nonsurgical perforations were greater than those for surgical perforations ( P < .001). Conclusion Height is less than length in over 90% of septal perforations. Most perforations assume an elliptical shape as they enlarge. Accurate measurement and presentation of length and height is relevant information to perforation management decisions and for the evaluation of treatment outcomes.

AbstractObjectiveCritical components of the nasal endoscopic examination have not been definitively established for either the normal examination or for clinical disorders. This study aimed to identify concordance among rhinologists regarding the importance of examination findings for various nasal pathologies.Study DesignA consortium of 19 expert rhinologists across the United States was asked to rank the importance of findings on nasal endoscopy for 5 different sinonasal symptom presentations.SettingAn online questionnaire was distributed in July 2023.MethodsThe questionnaire utilized JotForm® software and featured 5 cases with a set of 4 identical questions per case, each covering a common indication for nasal endoscopy. Rankings were synthesized into Normalized Attention Scores (NASs) and Weighted Normalized Attention Scores (W‐NASs) to represent the perceived importance of each feature, scaled from 0 to 1.ResultsGeneral concordance was found for examination findings on nasal endoscopy within each case. The perceived features of importance differed between cases based on clinical presentation. For instance, in evaluating postnasal drip, the middle meatus was selected as the most important structure to examine (NAS, 0.73), with mucus selected as the most important abnormal finding (W‐NAS, 0.66). The primary feature of interest for mucus was whether it was purulent or not (W‐NAS, 0.67). Similar analyses were performed for features in each case.ConclusionThe implicit framework existing among rhinologists may help standardize examinations and improve diagnostic accuracy, augment the instruction of trainees, and inform the development of artificially intelligent algorithms to enhance clinical decision‐making during nasal endoscopy.

ObjectiveThe Nasal Obstruction Symptom Evaluation (NOSE)‐Perf scale was developed and validated to measure symptoms associated with nasal septal perforations. This study reports the application of the NOSE‐Perf scale to evaluate symptom change following septal perforation repair.MethodsPatients with NOSE‐Perf evaluations ≥6 months following attempted perforation closure from July 2018 to December 2021 utilizing bilateral nasal mucosal flaps with an interposition graft were eligible for study inclusion. Change in NOSE‐Perf scores were noted. Patient demographics, perforation size, and concurrent functional procedures were analyzed for impact on symptom outcomes.ResultsOne‐hundred and seventeen patients met the study criteria. Seventy‐nine (67.5%) of the patients were female and the mean (range) age at surgery was 47.3 (14–78) years. Repair failure was noted in 7 (6.0%) patients. Mean (SD) preoperative NOSE‐Perf score was 25.3 (95% CI, 23.5–27.1) and postoperative score was 7.9 (95% CI, 6.5–9.3). Minimal clinically important difference (MCID) was estimated and greater than 91% of patients had improvement above this threshold. Patient age, perforation size, or concurrent functional procedures did not impact outcomes. Postoperative scores at short (2–4 months), intermediate (5–8 months), and long‐term (≥9 months) time periods showed significant improvement (all p < 0.001) compared to preoperative NOSE‐Perf scores.ConclusionSignificant reduction in nasal symptoms as measured by the NOSE‐Perf scale is noted following bilateral mucosal flap repair. Although the nose does not completely normalize following repair, clinically important improvement was noted in at least 91% of patients. The NOSE‐Perf scale is positioned to play a role in the standardization of septal perforation evaluation and outcomes assessment.Level of Evidence4 Laryngoscope, 134:3067–3072, 2024

BackgroundNasal septal perforations (NSP) can have a heterogeneous appearance on endoscopic examination with varying degrees of crusting, inflammatory change, and associated septal deviation. The clinical applicability of these findings as contributors to patient symptoms may be enhanced by use of a standardized assessment.MethodsVideo nasal endoscopy recordings were obtained from 40 patients with NSP. Five raters with varied levels of training ranging from a senior resident to an experienced septal perforation surgeon independently reviewed the videos for the following exam findings: crusting, scarring, granulation tissue, septal deviation, and edema. Scoring for each item was reported on a 3‐point (0–2) scale, and each reviewer repeated scoring at a 14‐day interval. Interrater and intrarater agreement were calculated using Fleiss kappa for each item and the total scores. Additionally, endoscopy scores were correlated with patient‐reported NOSE‐Perf symptom scores.ResultsInterrater agreement for the overall instrument was in the “fair‐to‐moderate” range with the following interrater agreement for each item: crusting (0.458–0.575), scarring (0.286–0.308), granulation (0.403–0.406), deviation (0.487–0.494), and edema (0.253–0.406). Intrarater agreement was generally “substantial” for individual items as well as the overall instrument (0.688). The NSP endoscopy scores were moderately correlated with NOSE‐Perf scores (r = 0.44, p = 0.008).ConclusionsAn endoscopic evaluation of NSP comprising five exam findings has acceptable interrater and intrarater reliability and correlates with patient‐reported outcomes. NSP endoscopy may be applied to future clinical studies for characterization of NSP and assessment of treatment outcomes.Level of Evidence3 Laryngoscope, 134:3049–3053, 2024

Key Points Combined endoscopic sinus surgery and nasal septal perforation repair is technically feasible. NOSE‐Perf is a recently developed patient‐reported outcome measure for nasal septal perforation. The decision to perform combined ESS and NSP repair should be made on a case‐by‐case basis.

Background Epigenetics studies mechanisms such as DNA methylation, histone modifications, non-coding RNAs, and alternative polyadenylation that can modify gene activity without changing the underlying DNA nucleotide base-pair structure. Because these changes are reversible, they have potential in developing novel therapeutics. Currently, seven pharmaceutical agents targeting epigenetic changes are FDA approved and commercially available for treatment of certain cancers. However, studies investigating epigenetics in chronic rhinosinusitis (CRS) have not been undertaken previously in the United States. Objectives The goal of this study was to investigate sinonasal DNA methylation patterns in CRS versus controls, to discern environmentally-induced epigenetic changes impacting CRS subjects. Methods and Results Ethmoidal samples from CRS and inferior turbinate mucosal tissue samples from controls without CRS were studied. DNA methylation was studied by Reduced Representation Bisulfite Sequencing. RADMeth® biostatistical package was used to identify differentially methylated regions (DMRs) between CRS and controls. Ingenuity Pathway analysis of DMRs was performed to identify top upstream regulators and canonical pathways. Ninety-three samples from 64 CRS subjects (36 CRSwNP; 28 CRSsNP) and 29 controls were studied. CRS and control samples differed in 13 662 CpGs sites and 1381 DMRs. Top upstream regulators identified included: 1. CRS versus controls: TGFB1, TNF, TP53, DGCR8, and beta-estradiol. 2. CRSwNP versus controls: TGFB1, CTNNB1, lipopolysaccharide, ID2, and TCF7L2. 3. CRSsNP versus controls: MYOD1, acetone, ID2, ST8SIA4, and LEPR. Conclusions Differential patterns of methylation were identified between controls and CRS, CRSwNP, and CRSsNP. Epigenetic, environmentally-induced changes related to novel, inflammatory, immunologic, and remodeling pathways appear to affect epithelial integrity, cell proliferation, homeostasis, vascular permeability, and other yet uncharacterized pathways and genes.
