RESUMEN
Objective:To analyze the factors influencing the outcome of uvulopalatopharyngoplasty in positional obstructive sleep apneaï¼POSAï¼ and non-positional OSAï¼NPOSAï¼ patients, and to explore the differences between the two groups. Methods:The data of 101 patients with obstructive sleep apnea who received treatment from November 2020 to November 2023 were retrospectively analyzed. Among them, 45 positional patientsï¼POSA groupï¼ and 56 non-positional patientsï¼NPOSA groupï¼, who underwent overnight polysomnography were included. The upper airwayï¼UAï¼ anatomy was evaluated by three-dimensional computer tomographyï¼3D-CTï¼. All patients received revised uvulopalatopharyngoplasty with uvula preservation and were followed using polysomnography for at least three months postoperatively. Results:The overall effective rate was 55.45%. The surgical success rate in POSA undergoing UPPP was higher than NPOSAï¼POSA 30/45, 66.7% versus NPOSA 26/56, 46.4%, P=0.042ï¼. The H-UPPP effect of POSA was negatively correlated with the minimum lateral airway of the Velopharyngeal airwayï¼r=-0.505, P<0.001ï¼, the minimum lateral airway of the glossopharyngeal airwayï¼r=-0.474, P=0.001ï¼ and the minimum cross-sectional areaï¼r=-0.394, P=0.007ï¼. Logistic analysis showed that minimal lateral airway of the glossopharynxgeumï¼mLATï¼ï¼OR 0.873; 95%CI 0.798-0.955, P=0.003ï¼ was a significant predictor for surgical outcomes among POSA patients. In NPOSA, ageï¼OR 0.936; 95%CI 0.879-0.998, P=0.042ï¼ was a significant predictor for surgical outcomes. Conclusion:The effect of H-UPPP was higher in POSA than in NPOSA. The width of glossopharyngeal mLAT was an important predictor of POSA efficacy. Age was a predictor of NPOSA efficacy.

BACKGROUND: Emergence delirium is a complication of pediatric anesthesia during the early recovery period. Children undergoing ear, nose, and throat surgery are at high risk. The Pediatric Assessment of Emergence Delirium (PAED) scale is used for diagnosis and founded to specify the degree of emergence delirium. However, there is no consensus regarding a threshold value for emergence delirium diagnosis. Homeostasis-guided pediatric general anesthesia aims to maintain physiological parameters within normal ranges. In this prospective, observational study we evaluated the incidence of emergence delirium in children undergoing elective ear, nose, and throat surgery under standardized homeostasis-guided general anesthesia. Secondarily, we identified risk factors associated with an increased PAED score. METHODS: In children aged 0-6 years, we collected data from standard monitoring, depth of anesthesia, and preoperative glucose and ketone body levels. These variables were studied as risk or protective factors for increased PAED >0 scores using multivariate logistic regression. RESULTS: Of the 105 children analyzed, only five children (4.7%) had emergence delirium according to a threshold PAED score ≥10, while 37 children (35%) had PAED scores >0. Statistical analysis of the PAED outcome identified two significant positive associations with pain (P<0.001) and preoperative blood glucose levels (P=0.006) and one negative association with preoperative ketone body levels (P<0.001). CONCLUSIONS: Our cohort observed a lower incidence of emergence delirium than in the literature. Higher pain intensity and lower blood glucose levels were risk factors for PAED > 0, whereas preoperative ketone body levels were protective.

OBJECTIVES: To assess the extent of staff exposure to aerosol generation in common pediatric otorhinolaryngological procedures (tonsillotomies, adenoidectomies, and tympanostomies) and determine the surgical phases responsible for most aerosol generation in these procedures. METHODS: Aerosol generation was measured during 35 pediatric otolaryngological procedures using an Optical Particle Sizer that measures aerosol concentrations for particle sizes between 0.3 and 10.0 µm. The different phases of and instruments used in each procedure were logged. Operating room background aerosol levels and coughing were used as references. RESULTS: Total aerosol concentrations were significantly higher during tonsillotomies and adenoidectomies when compared to tympanostomies (p = 0.011 and p = 0.042) and to empty room background aerosol concentrations (p = 0.0057 and p < 0.001). Aerosol concentration during tonsillotomies did not differ from coughing, which is considered as standard for high-risk aerosol procedures. During tympanostomies, aerosol concentrations were even lower than during perioperative concentrations. No statistically significant difference in aerosol generation comparing suction, electrocautery, cold instruments, and paracentesis was found. CONCLUSION: According to the results of this study, tympanostomies are low-risk aerosol-generating procedures. On the other hand, pediatric tonsillotomies produced aerosols comparable to coughing, pointing to them being significantly aerosol-producing procedures and viral transmission is theoretically possible intraoperatively.

Obstructive sleep apnea (OSA) syndrome is not only a widespread pathology, but also has far-reaching social consequences due to patients' poor quality of nighttime sleep and high daytime sleepiness. To date, a large number of methods, both conservative and surgical, have been developed for the treatment of OSA. Surgeries performed for OSA are aimed at correcting the structures of the nose, pharynx, larynx, as well as the hyoid and jaw bones and the muscles attached to them. Despite the seventy-five-year history of the use of surgical treatment methods, there is still no complete clarity regarding the advisability of certain types of operations. The article presents data from meta-analyses published over the last ten years and devoted to various types of surgical procedures aimed at combating OSA in adult and pediatric populations. Rhinosurgical approaches, uvulopalatopharyngoplasty, surgical advancement of the lower jaw in adults and expansion of the upper jaw in children, interventions on the hyoid bone and mental tubercle, removal of the palatine and pharyngeal tonsils, operations for laryngomalacia and bariatric surgery are considered. Data on the effectiveness of the most common operations: tonsillectomy in adults (85%), multilevel pharyngoplasty (60%); and about a wide range of data on the effectiveness of uvulopalatoplasty (25 to 94%) are presented. Effective surgical options and criteria for a positive prognosis of such treatment, the possibility of complete cure of OSA, that is, reducing the apnea/hypopnea index (AHI) below 5 events per hour in adults, are discussed. In conclusion, the need to continue research using Sher's criteria for the effectiveness of surgical operations is emphasized: a reduction in AHI by 50% or more or below 20 events per hour. Research that includes long-term postoperative follow-up is especially important.

OBJECTIVE: Three-dimensional (3D) endoscopy has been developed to provide depth perception to allow for improved visualisation during otolaryngology surgery. We conducted a systematic review to determine the surgical safety and efficacy of 3D endoscopy in comparison to two-dimensional (2D) endoscopy in performing otolaryngology procedures, and the role of 3D endoscopy as a training tool for novice otolaryngology surgeons. METHODS: Primary studies were identified through MEDLINE, Embase and Web of Science databases, which were searched for articles published through June 2022 that compared the outcomes of 2D and 3D endoscopy in otolaryngology surgical procedures or otolaryngology-relevant simulations. Candidate articles were independently reviewed by two authors. RESULTS: A total of 18 full-text articles met inclusion criteria for this study. In clinical trials (n = 8 studies, 362 subjects), there were no significant differences in performance time, intraoperative or postoperative complications with 3D endoscopes when compared to 2D. In simulation studies (n = 10 studies, 336 participants), 3D endoscopes demonstrated a decreased error rate (n = 5 studies) and shorter performance time (n = 3 studies). Studies also reported improved depth perception (n = 14 studies) and visualisation preference (n = 5 studies) with 3D over 2D systems. The 3D systems were found to have a shorter learning curve and better manoeuvrability among novice surgeons. CONCLUSION: 3D endoscopy showed equivalent safety and efficacy compared to 2D endoscopy in otolaryngology surgery. The improved depth perception and performance for novices using 3D endoscopes suggests the technology may be superior to 2D endoscopes as a training tool for otolaryngology surgeons.

OBJECTIVES: The author discusses current otolaryngological procedures employing the palatopharyngeus muscle, based on the surgical anatomy of the muscle and its neural supply. These techniques should be deeply revised for more conservative, anatomically-based maneuvers. METHODS: Revision of anatomical and surgical research and comments with the provision of a primary concept. RESULTS: The palatopharyngeus muscle is innervated by the pharyngeal plexus (the vagus and the accessory nerves) with additional fibers from the lesser palatine nerves. The innervation enters the muscle mainly through its lateral border. CONCLUSIONS: The palatopharyngeus muscle has a fundamental role in swallowing and speech. The muscle helps other dilators to maintain upper airway patency. Sphincter pharyngoplasty should be revised as regards its role as a sphincter. Palatopharyngeal procedures for OSA employing the palatopharyngeus muscle should follow the conservative, anatomically-based, and non-neural ablation concept.

PURPOSE: To evaluate pre- and post-operative resonance, surgical technique, revision rate, and revision indication among syndromic and non-syndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: A systematic review was conducted through July 2022. Children surgically treated for VPI were included. A meta-analysis of single means, proportions, comparison of proportions, and mean differences with 95 % confidence interval [CI] was conducted. RESULTS: Twenty-three articles (n = 1437) were included in the analysis. The most common surgery was Sphincter Pharyngoplasty (SP), 62.6 % [31.3-88.9] for syndromic and 76.3 % [37.5-98.9] for non-syndromic children. Among all surgical techniques, for syndromic and non-syndromic children, 54.8 % [30.9-77.5] and 73.9 % [61.3-84.6] obtained normal resonance post-operatively, respectively. Syndromic patients obtained normal resonance post-operatively in 83.3 % [57.7-96.6] of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty (CPSP), 72.6 % [54.5-87.5] of Pharyngeal Flap (PF), and 45.1 % [13.2-79.8] of Sphincter Pharyngoplasty (SP) surgeries. Non-syndromic patients obtained normal resonance post-operatively in 79.2 % [66.4-88.8] of PF and 75.2 % [61.8-86.5] of SP surgeries. The revision rate for syndromic and non-syndromic patients was 19.9 % [15.0-25.6] and 11.3 % [5.8-18.3], respectively. The difference was statistically significant, 8.6 % [2.9-15.0, p = 0.003]. Syndromic patients who underwent PF were least likely to undergo revision surgery as compared to SP and CPSP, 7.7 % [2.3-17.9] vs. 23.7 % [15.5-33.1] and 15.3 % [2.8-40.7], respectively. CONCLUSIONS: Syndromic children had higher revision rates and were significantly less likely to obtain normal resonance following primary surgery than non-syndromic patients. Among syndromic children, PF and CPSP have been shown to improve resonance and reduce revision rates more so than SP alone.

BACKGROUND: Reducing the annotation burden is an active and meaningful area of artificial intelligence (AI) research. METHODS: Multiple datasets for the segmentation of two landmarks were constructed based on 41 257 labelled images and 6 different microsurgical scenarios. These datasets were trained using the multi-stage transfer learning (TL) methodology. RESULTS: The multi-stage TL enhanced segmentation performance over baseline (mIOU 0.6892 vs. 0.8869). Besides, Convolutional Neural Networks (CNNs) achieved a robust performance (mIOU 0.8917 vs. 0.8603) even when the training dataset size was reduced from 90% (30 078 images) to 10% (3342 images). When directly applying the weight from one certain surgical scenario to recognise the same target in images of other scenarios without training, CNNs still obtained an optimal mIOU of 0.6190 ± 0.0789. CONCLUSIONS: Model performance can be improved with TL in datasets with reduced size and increased complexity. It is feasible for data-based domain adaptation among different microsurgical fields.

Minimally invasive surgery (MIS) and robotics have revolutionized the field of Otolaryngology. MIS and robotics have reshaped traditional otolaryngological practices, offering patients a multitude of benefits. Reduced incision sizes and tissue manipulation minimize postoperative pain and discomfort, while also improving cosmetic outcomes. MIS has facilitated enhanced visualization and access to intricate anatomical structures, enabling the treatment of previously inaccessible lesions. MIS procedures also offer shorter hospital stays, reduced blood loss, and faster healing times whilst enhancing patient satisfaction and overall quality of life The ongoing progress in minimally invasive approaches solidifies their role as a cornerstone in modern Otolaryngology, and surgeons navigating this transformative landscape must embrace the learning curve associated with these advanced techniques, recognizing the potential for improved patient outcomes. This article explores the transformative impact of MIS and robotics on the diverse branches of Otolaryngology, highlighting the technological advancements that have enabled these techniques to flourish.

OBJECTIVE: To describe types and outcomes of elective otolaryngological surgeries undergone by patients ≥90 years of age and to assess whether very old age is an independent risk factor for postsurgical complications and death. METHODS: The National Surgical Quality Improvement Program, a validated national prospective surgical outcomes database, was used to identify all patients aged 65 years and older who underwent elective otolaryngological procedures from 2011 to 2020. Study outcomes included minor complications, major life-threatening complications, and 30-day mortality. Predictors of outcomes, including frailty, were identified using univariable analyses and age was added into the final logistic regression models with stepwise selection. RESULTS: A total of 40,723 patients met inclusion criteria; 629 (1.5%) patients were ≥90 years of age. Of the 63,389 procedures, head and neck (67.6%) and facial plastics and reconstructive (15.0%) procedures were most common. The overall incidence of major life-threatening complications, minor complications, and death was 2.0%, 3.5%, and 0.4%, respectively. Age ≥90 was significantly associated with an increased risk for 30-day mortality, but not with major or minor postoperative complications. A high modified frailty index was significantly associated with an increased risk for major postoperative complications and death amongst patients ≥90 years. CONCLUSIONS: Elective otolaryngological surgery can be safe in relatively healthy nonagenarians and centenarians, though there is a small increased risk of 30-day mortality. Although older age can predispose patients to other comorbidities, age alone should not deter surgeons and patients from considering elective otolaryngological procedures. Frailty may be a better predictor for surgical outcomes. LEVEL OF EVIDENCE: IV Laryngoscope, 134:3989-3996, 2024.

IMPORTANCE: Mobile apps in the field of ORL-HNS, are widely used by patients and physicians, but neither necessarily developed in collaboration with healthcare professionals nor subjected to regulations by the United States Food and Drug Administration guidelines, with a resultant potential of risk for its users. OBJECTIVE: To provide the ORL-HNS physician with an updated list of scientific peer review literature- validated mobile apps for safe use for both the clinician and the patients, for screening, diagnosis, therapy and follow up for various ORL-HNS pathologies. EVIDENCE REVIEW: A comprehensive systematic review of the scientific literature was conducted in "PubMed," "EMBASE," and "Web of Science" without limitation of publication date up to January 1st, 2023. The included papers validated mobile apps in the ORL-HNS discipline. Each study was evaluated using the "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE) tool. FINDINGS: From the thousands of unregulated ORL-HNS mobile apps available for download and use in the various app stores, only 17 apps were validated for safe use by the clinician and/or patient. Their information is listed. CONCLUSIONS AND RELEVANCE: The limited number of validated mobile apps highlights the importance to use validated apps in clinical practice, to improve evidence-based medicine and patient safety. Physician are encouraged to use and recommend their patients to use validated mobile apps only, like any other tool in clinical practice in the evidence-based era.

OBJECTIVE: To review current literature and guidelines on antiseptic surgical site preparations for preventing surgical site infections with consideration of contraindications specific to head and neck surgery. DATA SOURCES: PubMed/MEDLINE, clinicaltrials.gov, accessdata.fda.gov, Manufacturer websites. REVIEW METHODS: A scoping review on the literature and clinical studies comparing the efficacy of different surgical site preparations. Studies were included if they were a randomized controlled trial (RCT) comparing at least two commonly used and available antiseptic preparations. Additionally, a compilation of warnings and contraindications from manufacturer labels and articles are included. Due to the lack of randomized controlled trials concerning antiseptic preparation use in head and neck surgery specifically, an additional search was executed for articles not limited to randomized controlled trials that compared different antiseptic preparation used in surgeries concerning the head and neck. RESULTS: Of 56,983 resulting abstracts and 3798 of them being screened, 25 RCTs were included. These RCTs included a variety of surgeries including gastrointestinal, obstetric, gynecologic, orthopedic, and vascular procedures. When searching for abstracts concerning head and neck surgeries, 9 studies were found and included. CONCLUSIONS: To reduce surgical site infections and avoid application in situations with contraindications, practicing surgeons need to be familiar with the existing literature regarding different surgical preparations and what warnings manufacturers have listed on the products. Optimal surgical site preparation for head and neck surgery is challenging as proximity to oxygen contraindicates newer alcohol-based options that are potentially flammable. We summarize evidence-based surgical site preparation for head and neck surgery.

PURPOSE: There is sparse literature discussing the impact of smoking on postoperative outcomes following surgical treatment of Zenker's diverticulum. In this study, we seek to characterize differences in the management and outcomes of open Zenker's diverticulectomy based on patient smoking status. METHODS AND MATERIALS: This paper is a retrospective cohort review. The 2005-2018 American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for patients undergoing open Zenker's diverticulectomy. Chi-square and multivariable logistic regression were performed to determine statistical associations between postoperative outcomes and smoking status. RESULTS: Of the 715 identified patients, 70 (9.8 %) were smokers and 645 (91.2 %) were non-smokers. Smokers were younger than non-smokers (mean 63.9 vs. 71.7 years, p < 0.001) and more likely to have a prolonged operative time (20.0 % vs. 11.6 %, p = 0.044). On multivariable regression analysis controlling for demographics and comorbidities, smokers had greater odds than non-smokers for developing overall postoperative complications (OR: 2.776, p = 0.013), surgical infections (OR: 3.194, p = 0.039), medical complications (OR: 3.563, p = 0.011), and medical infections (OR: 1.247, p = 0.016). Smokers also had greater odds for requiring ventilation/intubation (OR: 8.508, p = 0.025) and having a prolonged postoperative stay (OR: 2.425, p = 0.030). CONCLUSION: In a cohort of patients undergoing transcervical Zenker's diverticulectomy, smokers are at increased risk for overall complications, medical complications, medical infections, surgical infections, prolonged postoperative stay, and ventilation/intubation.

BACKGROUND: Surgical procedures scheduled staggered between two operating rooms increase efficiency by eliminating turnover time. However, the practice might increase the surgeon's fatigue. Overlapping surgery has been assumed to be safe because no critical portions of procedures are performed simultaneously in two rooms, but there is little evidence in the literature to support that assumption for otolaryngologic surgery, and there is no evidence comparing non-overlapping and overlapping surgical outcomes for a single surgeon with all confounding factors controlled. METHODS: Retrospective cohort study that included a consecutive sample of adult subjects who underwent otolaryngologic laryngeal or otologic surgery between June 2013 and March 2016. All procedures were performed by the same surgical team and surgeon who had block time with 2-rooms every other week and 1-room on alternate weeks. The incidence of surgical complications was assessed in the perioperative period. Duration of surgery and time-in-room also were evaluated, as were surgical outcomes. RESULTS: A total of 496 surgeries were assigned to either overlapping-surgery (n = 346) or non-overlapping-surgery (n = 150) cohorts. Overlapping-surgery was a significant predictor for increased time-in-room on multivariate analysis but was not a significant predictor for surgery duration. Rate of complications, hospital readmission, emergency department visit, reoperation, mortality, and patient satisfaction did not differ significantly between cohorts. CONCLUSIONS: Overlapping surgery does not hinder patient safety or functional outcomes in patients undergoing otolaryngologic operations such as voice or ear surgery.
