Impact of adenotonsillectomy and palatal expansion on the apnea-hypopnea index and minimum oxygen saturation in nonobese pediatric obstructive sleep apnea with balanced maxillomandibular relationship: A cross-over randomized controlled trial.

OBJECTIVE: To determine the impact and best management sequence between adenotonsillectomy (AT) and rapid palatal expansion (RPE) on the apnea-hypopnea index (AHI) and minimum oxygen saturation (MinSaO2) in nonobese pediatric obstructive sleep apnea (OSA) patients presenting balanced maxillomandibular relationship. STUDY DESIGN/METHODS: Thirty-two nonobese children with balanced maxillomandibular relationship and a mean age of 8.8 years, with a graded III/IV tonsillar hypertrophy and maxillary constriction, participated in a cross-over randomized controlled trial. As the first intervention, one group underwent AT while the other underwent RPE. After 6 months, interventions were switched in those groups, but only to participants with an AHI > 1 after the first intervention. OSA medical diagnosis with the support of Polysomnography (PSG) was conducted before (T0), 6 months after the first (T1) and the second (T2) intervention. The influence of sex, adenotonsillar hypertrophy degree, initial AHI and MinSaO2 severity, and intervention sequence were evaluated using linear regression analysis. Intra- and intergroup comparisons for AHI and MinSaO2 were performed using ANOVA and Tukey's test. RESULTS: The initial AHI severity and intervention sequence (AT first) explained 94.9% of AHI improvement. The initial MinSaO2 severity accounted for 83.1% of MinSaO2 improvement changes. Most AHI reductions and MinSaO2 improvements were due to AT. CONCLUSIONS: Initial AHI severity and AT as the first intervention accounted for most of the AHI improvement. The initial MinSaO2 severity alone accounted for the most changes in MinSaO2 increase. In most cases, RPE had a marginal effect on AHI and MinSaO2 when adjusted for confounders.

Lidocaine and Dexamethasone, Ketamine and Dexamethasone, and Dexamethasone Alone in Tonsillectomy Complications.

Background: Common complications including stridor, laryngospasm, and bronchospasm are important in patients undergoing general anesthesia. Dexamethasone, lidocaine, and ketamine could have significant roles in reducing these complications. Here we aimed to compare the use of these drugs during tonsillectomy. Materials and Methods: This study was performed on 100 children that were candidates of tonsillectomy. Patients were divided into 4 groups receiving dexamethasone 0.1 mg/kg and lidocaine 1 mg/kg, ketamine 0.5 mg/kg and dexamethasone 0.1 mg/kg, dexamethasone 0.1 mg/kg, and normal saline after surgical procedures. We evaluated and compared data regarding the duration of anesthesia, oxygenation saturation, blood pressure (systolic and diastolic (SBP and DBP)), re-intubation, laryngospasm, bronchospasm, requiring analgesics after surgeries, recovery stay duration, and nausea and vomiting. Results: Administration of ketamine and dexamethasone was associated with the lowest pain and lowest need for postoperative analgesic administrations in patients (P = 0.02). Patients that received lidocaine and dexamethasone had the lowest frequencies of airway stimulations (P < 0.001). Evaluations of complications in patients revealed that stridor was significantly lower in patients that received ketamine and dexamethasone (P = 0.01). Conclusion: Usage of ketamine and dexamethasone was associated with the lowest pain severities and lowest complications. On the other hand, patients that received lidocaine and dexamethasone had the least airway stimulations.

Effects of branched-chain amino acids on changes in body composition during the recovery period following tonsillectomy.

PURPOSE: In recent decades studies have examined body weight changes following tonsillectomy. In nutrition science, the focus has shifted from body mass index to body composition analysis. However, no studies have explored body composition changes post-tonsillectomy. In oncology and digestive surgeries, the potential benefits of branched-chain amino acids (BCAAs) have been investigated; however, their effects on pharyngeal surgery remain unknown. Therefore, the aim of the present study was to investigate the body composition changes after tonsillectomy and to explore the potential benefits of branched-chain amino acids. METHODS: This prospective interventional controlled study enrolled 48 patients who were randomly assigned to a control group (CG) and an experimental group (EG). These groups were further divided into active and inactive subgroups on the basis of their activity levels. The EG consumed 2 × 4 mg of BCAA daily. Body composition was measured using bioimpedance (InBody 270) on the day of surgery and again on days 7 and 21 postoperatively. RESULTS: Both groups experienced similar weight loss; however, significant differences in body composition emerged. The CG showed significant muscle mass loss (from 30,29 to 28,51 kg), whereas active EG members maintained muscle mass (from 35,33 to 35,40 kg); inactive EG members increased muscle mass (from 26,70 to 27,56 kg) and reduced body fat percentage (from 31.94% to 29.87%). The general health status (InBody score) remained stable or improved in the EG (from 75,13 to 75,96); however, it decreased in the CG (from 75,42 to 72,67). CONCLUSION: The negative effects of tonsillectomy on body composition are mitigated by BCAA supplementation.

Outcome Prediction Model for Radiofrequency Uvulopalatopharyngoplasty with Tonsillectomy in Adult Obstructive Sleep Apnea: Retrospective Cohort Study.

Introduction: Knowing an individualized outcome prediction is essential when counseling patients before surgery. We aim to identify predictors and build a model for the outcome of radiofrequency uvulopalatopharyngoplasty with tonsillectomy (rfUPPP + TE). Methods: All adult patients undergoing rfUPPP + TE for sleep-disordered breathing from 2015 to 2022 in our institution were included. Preoperative evaluations included detailed upper airway examinations and standardized questionnaires. Postoperative outcomes were measured through home sleep apnea testing and repeated questionnaires 3 months post-surgery. The primary endpoint was the postoperative apnea-hypopnea index (AHI) and the AHI responders using the Sher criteria. Results: We analyzed 247 patients with a mean age of 46 ± 11 years, predominantly male (88.7%), and a mean BMI of 29.0 kg/m2. The mean AHI was reduced from 26.4 ± 18.6/h preoperatively to 16.2 ± 14.6/h postoperatively. Daytime sleepiness improved from 8.9 ± 48 to 4.0 ± 3.1 and snoring from 7.9 ± 2.1 to 3.3 ± 2.2. Multivariate analysis indicated that higher tonsil grades, preoperative AHI, and snoring levels were associated with a greater reduction in AHI. Age and body weight were negative predictors for AHI reduction. For AHI responders, according to Sher, tonsil grade was the only predictor in a multivariate analysis. The ROC curve of this simple model, with a corrected AUC of 0.625, compared favorably against two established models. Conclusion: Our study highlights that tonsil grade, preoperative AHI, snoring, and, to a smaller extent, age and weight are key determinants of AHI reduction, emphasizing the importance of preoperative evaluation. Despite the multifactorial nature of obstructive sleep apnea, preoperative evaluation can predict the outcome of rfUPPP + TE and guide surgical planning.

Soft palate surgery is the most frequently performed procedure for sleep-disordered breathing. Predicting individualized outcomes is essential in counseling patients on their expected results after surgery. In this retrospective analysis, we examined preoperatively available predictors, such as head and neck examination, sleep study, and questionnaires, in a cohort of 247 patients. The apnea-hypopnea index, a measure of sleep-disordered breathing severity, showed a greater reduction in patients with large tonsils, heavy self-reported snoring, and a higher preoperative apnea-hypopnea index. Higher age and body weight negatively impacted results after soft palate surgery. The study highlights the importance of preoperative evaluation, especially regarding tonsil grade and upper airway anatomy. Despite the multifactorial nature of obstructive sleep apnea, surgical outcomes can be predicted with careful assessment.

Postoperative Analgesic Regimens and Their Satisfaction Rates-Data from the Swedish Quality Register for Tonsil Surgery.

OBJECTIVE: To describe postoperative analgesic regimens and patient-reported pain-related outcomes after tonsil surgery. METHODS: Cohort study including perioperative data (n = 9274) and patient-reported outcome measures (n = 5080) registered in the Swedish Quality Register for Tonsil Surgery during 2023. RESULTS: After tonsil surgery, 92.7% received at least paracetamol and a NSAID/COX inhibitor, while 6.8% received no NSAID/COX inhibitor. Opioids were prescribed after tonsillectomy to 62.9% of adults and less often to adolescents and children (13-17-year-olds: 48.2%, 6-12-year-olds: 8.8%, 0-5-year-olds: 4.0%). Clonidine was frequently prescribed to 0-5-year-olds after tonsillectomy (54.4%). Overall, 11.7% reported dissatisfaction with the pain treatment, with the highest dissatisfaction rate after tonsillectomy in adolescents (20.6%) and adults (20.0%), and the lowest after tonsillotomy in children (4.9-6.8%). The most common complaint among dissatisfied patients was analgesics not being sufficiently helpful. Adult patients who received addition of opioids were less dissatisfied with the pain treatment (15.9% vs. 25.9%, p < 0.001), but also reported more side effects (5.7% vs. 2.7%, p = 0.039), compared with patients who received only paracetamol and NSAID/COX inhibitors. CONCLUSION: Tonsil surgery patients in Sweden receive various analgesic regimens. Although most are satisfied with pain treatment, there is room for improvement, particularly among adolescents and adults undergoing tonsillectomy. Paracetamol and a NSAID/COX inhibitor seem advisable as basic treatment. However, many patients need more effective treatment. The addition of opioids in adults results in greater satisfaction with pain treatment, but safety issues with opioid prescriptions must be taken into consideration.

Perioperative opioids in high-risk children undergoing tonsillectomy - A single institution experience.

BACKGROUND: Patients undergoing tonsillectomy/ adenotonsillectomy (T/AT) can experience substantial postoperative pain. The aims of this study are to assess perioperative pain management in high-risk children (children with severe obstructive sleep apnea and other complex medical comorbidities or age younger than 2 years) undergoing T/AT, and the impact on oxygen levels and pain during extended Post-Anesthesia Care Unit (PACU) admission. METHODS: A retrospective case series study at a tertiary care children's hospital. RESULTS: There were 278 children enrolled in the study. The Apnea-Hypopnea index and mean oxygen nadir on preoperative polysomnography were 31.3 ± 25.76/h and 79.5 ± 9.5 % respectively. Overall, 246 (89 %) patients received intraoperative opioids alone (n = 35, 13 %) or in combination with non-opioid analgesia (n = 209, 75 %). While the median dose of opioid-free medications (acetaminophen, ibuprofen) ranged from 93 to 100 % of standard maximal dosing by weight and age, the median dose of opioids was significantly lower and ranged from 54 to 63 % of standard maximal dosing by weight and age, with 43 % of the patients receiving less than half the recommended maximum dose. Oxygen desaturation was charted in 21 patients (8 %) during their PACU admission. Patients who received opioid-free analgesia were as likely to develop oxygen desaturations (n = 17 (81 %) vs. n = 228 (89.4 %), p = 0.27) and to receive rescue pain medication during their PACU stay as patients who received opioids intraoperatively (n = 18 (56 %) vs. n = 167 (68 %), p = 0.23). CONCLUSIONS: Intraoperative pain management varies across high-risk pediatric tonsillectomies. Opioid-free analgesia was not associated with an increased need for pain medications during PACU admission, or with a decreased likelihood of oxygen desaturations compared to intra-operative opioid analgesia use.

[Immunosuppression, tonsillectomy and remissions in high-risk IgA-nephropathy].

AIM: To evaluate the efficacy of immunosuppressive therapy (IST) and tonsillectomy (TE) in patients with high-risk IgA nephropathy (IgAN). Materials and мethods. The retrospective study cohort included cases with primary IgAN (n=213, age 34±11 years, male 52%) at high risk of progression with clinical and morphological data collected. The follow-up was 26 (10; 61) months. The association of IST without TE (IST; n=141) or with TE (IST+TE; n=72) with the development of complete (PR), partial (PR) and overall (PR or PR, OR) remissions was investigated. RESULTS: The incidence of achieving early PR or OR in the IST and IST+TE groups was 65.2% and 86.1%, respectively (p=0.002). The probability of early PR or OR was significantly increased in the IST+TE group compared to IST [HR 1.714 (1.214-2.420) and HR 3.410 (1.309-8.880), respectively]. IST+TE was associated with a 3- to 4-fold increase in the likelihood of PR or OR at the end of follow-up [HR 2.575 (1.679-3.950) and HR 4.768 (2.434-9.337), respectively]. Analyses using pseudorandomisation methods yielded similar results. CONCLUSION: TE may be effective for remission induction in high-risk IgAN.

Effect and safety of perioperative ibuprofen administration in pediatric tonsillectomy: A systematic review and meta-analysis.

OBJECTIVES: This study aimed to evaluate the safety and efficacy of perioperative ibuprofen administration by conducting a meta-analysis of pertinent literature. METHODS: We conducted a comprehensive review of studies sourced from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases. The studies covered the period from database inception to June 2024. A perioperative ibuprofen administration group was compared to a control group administered either saline, acetaminophen, paracetamol, or opioids. The primary outcome was post-tonsillectomy bleeding that was categorized into overall bleeding and further classified as type 1 (observed at home or evaluated in the emergency department without additional intervention), type 2 (necessitating readmission for observation), and type 3 (requiring a return to the operating room for hemorrhage control). Morbidity incidence rates for postoperative nausea and vomiting were also assessed. The secondary outcomes assessed were postoperative pain management and the frequency of analgesic drug usage. Postoperative pain management was assessed from the incidence of emergency department visits or nurses' calls for pain independent of the presence or absence of dehydration. RESULTS: Twenty-two studies with 27,149 patients were included and reviewed for this meta-analysis. Post-tonsillectomy bleeding (OR = 0.9954, 95 % CI [0.8800; 1.1260], I2 = 0.0 %) was not significantly higher in the ibuprofen administration group compared to the control group. In subgroup analysis of post-tonsillectomy bleeding severity, ibuprofen caused clinically insignificant type 1 post-tonsillectomy bleeding that did not require intervention (OR = 1.1310 [0.7398; 1.7289]). Clinically significant bleeding requiring hospital admission (type 2) or surgical control (type 3) was not observed. Administration of ibuprofen has demonstrated efficacy in reducing the need for analgesic drugs (OR = 0.4734, 95 % CI [0.2840; 0.7893]; I2 = 19.8 %) and is associated with a significant decrease in the incidence of postoperative nausea and vomiting (OR = 0.4886, 95 % CI [0.3156; 0.7562], I2 = 34.3 %). CONCLUSION: This study demonstrated that administration of ibuprofen for pediatric tonsillectomy did not increase the incidence of clinically significant postoperative bleeding. Ibuprofen administration decreased the incidence and severity of postoperative pain, nausea, and vomiting.

Association of Helicobacter Pylori in Chronic Tonsillitis.

The objective of the study was to detect the presence of Helicobacter pylori in adenotonsillar tissue and to assess the association between the presence of H pylori with Chronic Tonsillitis or Adenotonsillitis. This was a cross sectional study conducted among 60 patients diagnosed with chronic tonsillitis and adeno tonsillitis undergoing tonsillectomy or adeno tonsillectomy meeting the paradise criteria in a tertiary care hospital, Pondicherry. Rapid urease test was done in the intraoperative period immediately after the specimens were taken.The rapid urease test kit was observed for color change from yellow to pink within 4 h. The tissue was sent for histopathological examination for staining with H&E and Giemsa stain to detect the presence of helicobacter pylori. The mean age of the study participants was 15.75 ± 8.46 and majority of the study participants were females. (61.7%). 66.7% and 33.3% of the study participants had chronic tonsillitis and adeno tonsillitis respectively. Oral swab showed normal flora, yeast and methicillin resistant Staphylococcus aureus in 96.6%, 1.7% and 1.7% respectively. 1.7% (1),13.3% (8) and 20% (12) of the study participants showed positive in card test immediate, at 15 min and 1 h respectively. Giemsa stain showed that 11.7% was positive for H.pylori. Out of the 7 patients with positive Giemsa stain, 4 had chronic tonsillitis and 3 had adenotonsillitis. Colonisation of adenoids and tonsils by H. pylori is a novel forefront with contradictory results dependent on the precision of the detective techniques used and population studied. Further research may be warranted to establish the varied colonisation depending on the geographical locations.

Combination Tonsillectomy and Hypoglossal Nerve Stimulation for Sleep Apnea Patients With Oropharyngeal Lateral Wall Collapse.

OBJECTIVE: The efficacy of hypoglossal nerve stimulation (HGNS) therapy is limited by obstruction of the oropharyngeal lateral walls (OLWs). Our objective was to investigate the effect of palatine tonsillectomy on HGNS efficacy in obstructive sleep apnea (OSA) patients with OLW collapse. STUDY DESIGN: Case-control study of patients with moderate-to-severe OSA, complete-or-partial OLW collapse, and small tonsils (1 - 2+). Concomitant palatine tonsillectomy and HGNS (HGNS+T) were compared against a control group of patients who underwent HGNS alone. SETTING: Single academic institution. METHODS: Study outcomes were measures of HGNS efficacy defined as a %reduction in apnea-hypopnea index (AHI) (primary) and successful treatment response (50% AHI reduction to <15/h, logistic regression), respectively. Regression analyses quantified the additional effect of tonsillectomy (HGNS+T vs HGNS alone, independent variable) on HGNS efficacy. Analyses were adjusted for OLW collapse severity (complete vs partial), tonsil size, age, sex, body mass index, and baseline AHI. RESULTS: Nineteen patients underwent HGNS+T and had follow-up sleep testing for the current analysis. The control group (HGNS alone) consisted of 78 patients. Baseline demographics and OSA severity were similar between the groups, except HGNS+T group had increased prevalence of complete OLW collapse. Linear regression demonstrated that adding tonsillectomy resulted in an additional 22.9% [7.5, 35.2] reduction in AHI [95% confidence interval, CI] (P = .006), and 8.6 [1.7,43.4] (P = .010) greater odds [95% CI] of a successful treatment response with HGNS. CONCLUSION: Compared to historically poorer outcomes of HGNS in patients with OLW collapse, these early results suggest combining tonsillectomy with HGNS may represent a promising strategy to improve success rates.

[Long-term effect observation after 10 years of tonsillotomy （Histological analysis of one case of secondary operation）].

Objective:To investigate the long-term effect of partial tonsillectomy in children with tonsil hypertrophy. Methods:A total of 146 children with obstructive sleep apnea（OSA） who received surgical treatment for tonsil hyperplasia from January 2010 to January 2013 were selected and divided into the observation group（n=69） and the control group（n=77）. The observation group was received tonsillotomy（TT）, and the control group was received total tonsillectomy（TE）. Parental satisfaction and OSA quality of life questionnaire for children（OSA-18） were surveyed. Residual tonsil size was measured, and polysomnography（PSG） was monitored after 10 years. HE and immunohistochemical analysis were performed on tonsil tissues of one patient who performed a second operation after TT in 2017 year. Results:The results of questionnaire survey showed that the symptoms of respiratory obstruction were significantly improved in both groups, and the satisfaction of TT group was higher than that in the TE group. No increase in the number of respiratory tract infections was observed in all patients. In the TT group, nine cases（13.04%） had tonsil hyperplasia toⅡ°, and the remaining patients had tonsil hyperplasia to Ⅰ°. In addition, one case hadtonsil suppurative infection at the 14th month after surgery, and no recurrence or reoperation was found after treatment. There were seven cases in the TT group and eight cases in the TE group with occasional snoring and mouth breathing after surgery, but the PSG examination of the patients did not meet the diagnosis of OSA. The main causes were obesity and allergic rhinitis. Compared with the first operation, the cicatricial obstruction and infection of tonsil tissue in the second operation were not significantly changed, and the immunohistochemical results also demonstrated that the expression of CD20 was not changed, and the expression of CD3 was decreased. Conclusion:Both TT and TE can effectively improve the symptoms of OSA obstruction in children. TT has less trauma, less postoperative pain, faster recovery and lower rate of hyperplasia, which can be used as one of the main methods for the treatment of tonsil hypertrophy in children.

Lidocaine and risk of postoperative vomiting in children undergoing tonsillectomy: a randomised clinical trial.

The dose-response of intravenous lidocaine in preventing postoperative vomiting (POV) in children remains unclear. This study investigated whether intravenous lidocaine dose-dependently decreased POV risk within 24 h postoperatively in children undergoing tonsillectomy (with or without adenoidectomy) without severe complications. Patients aged 3-12 years (American Society of Anesthesiologists grade I-II) scheduled for elective tonsillectomy (with or without adenoidectomy) were enroled from December 2021 to March 2022. They were randomly grouped according to the lidocaine dose (A [0 mg kg-1], B [1 mg kg-1], C [1.5 mg kg-1], and D [2 mg kg-1]) and were administered the same induction protocol (sufentanil, propofol, and suxamethonium chloride). Anaesthesia was maintained with sevoflurane. The incidence of POV within 24 h postoperatively was 46, 40, 36, and 20% in groups A, B, C, and D, respectively, with significant differences between groups D and A. Postoperative analgesic rescues in groups A, B, C, and D were 62, 36, 34, and 16%, respectively, with significant differences between groups D and B, C and A, and D and A. No severe adverse events were reported. Intravenous lidocaine has a dose-dependent effect on reducing the risk of POV in children undergoing tonsillectomy (with or without adenoidectomy) without serious adverse events.Trial registration: Chinese Clinical Trial Registry, ChiCTR2100053006.

Efficacy and safety of perioperative ibuprofen for pain control after pediatric tonsillectomy: A systemic review and meta-analysis.

OBJECTIVES: To assess the safety and effectiveness of perioperative ibuprofen in pediatric tonsillectomy through a meta-analysis of relevant randomized controlled trials. METHODS: We conducted a comprehensive review of studies available in PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases up to June 2024. This analysis compared perioperative ibuprofen administration to control groups (saline, acetaminophen, or opioids). Outcomes assessed were postoperative pain management, as indicated by the frequency of analgesic use, and morbidity rates, which included the incidence of postoperative nausea and vomiting and post-tonsillectomy hemorrhage (PTH). PTH was further categorized as primary (occurring on the day of operation) or secondary (occurring after the day of operation), and classified as type 1 (observed at home or evaluated in the emergency department without further intervention), type 2 (requiring readmission for observation), or type 3 (necessitating a return to the operating room for hemorrhage control). RESULTS: This analysis included nine studies involving a total of 1545 patients. Incidences of primary PTH (OR = 1.0949, 95 % CI [0.4169; 2.8755], I2 = 0.0 %), secondary PTH (OR = 1.6433 95 % CI [0.7783; 3.4695], I2 = 0.1 %), and overall PTH (OR = 1.4296 95 % CI [0.8383; 2.4378], I2 = 0.0 %) were not significantly higher in the ibuprofen group than the control groups. Administration of ibuprofen led to a significant decrease in postoperative nausea and vomiting (OR = 0.4228 95 % CI [0.2500; 0.7150], I2 = 40.0 %) and frequency of postoperative analgesic uptake (OR = 0.4734 95 % CI [0.2840; 0.7893]; I2 = 19.8 %). There was no difference in bleeding by type between the ibuprofen and control groups. CONCLUSIONS: Our meta-analysis demonstrated that administration of ibuprofen for pediatric tonsillectomy did not significantly increase the incidence of postoperative bleeding but did decrease postoperative emesis and improve pain control.

National survey on peritonsillar abscess treatment and attitudes toward quinsy tonsillectomy.

OBJECTIVES: Peritonsillar abscess (PTA) is a common deep neck infection traditionally managed with conservative measures. Quinsy Tonsillectomy (QT) is recognized as a definitive treatment but remains variably utilized. We aimed to investigate PTA management strategies and attitudes toward QT among otolaryngologists. METHODS: An anonymous questionnaire was distributed to members of the local national Society of Otolaryngology, evaluating treatment strategies based on patient characteristics and clinical scenario. RESULTS: A total of 108 otolaryngologists responded (response rate: 30.8%). Participants preferred to treat PTA patients as inpatients (89%) and predominantly offered incision and drainage (I&D) as the first (90.7%) and subsequent (98.1%) treatment plan. QT was favored as a primary treatment only in 1.9% of responders. QT adoption increased with multiple I&D failures, reaching 95.3% after four attempts. In patients with recurrent PTA or tonsillitis, 84.2% preferred I&D follows by interval elective tonsillectomy, while 15% considered QT. The most common reason (72.2%) to avoid QT was the perception of a high perioperative risk. CONCLUSION: I&D was favored for initial PTA treatment. QT is considered after multiple failed I&D attempts, and its use is limited as a primary treatment, mainly due to concerns regarding perioperative risk.

Effect of dexmedetomidine on postoperative adenotonsillectomy oral intake and dehydration.

OBJECTIVE: To determine if perioperative administration of dexmedetomidine affects postoperative fluid intake in tonsillectomy patients. METHODS: A retrospective chart review was performed at University Medical Center, Texas Tech Health Science Center, Lubbock, Texas. The study identified 534 patients within the last five years who met the criteria. Common indications for the surgeries included recurrent tonsillitis, obstructive sleep apnea, and sleep disordered breathing. Patients with concurrent peritonsillar abscess drainage, microlaryngoscopy, bronchoscopy, supraglottoplasty, and other procedures that may impact fluid intake were excluded. The relationship between dexmedetomidine and fluid intake was evaluated using bivariate analysis as well as multivariable regression to account for possible confounders such as age, concurrent medication, surgery type, and method of surgery using STATA statistical software, version 17.0 (StataCorp LLC, College Station, TX). RESULTS: Administration of dexmedetomidine did not significantly impact the amount of fluid intake, fluid intake per kilogram per hour, or average postoperative pain levels in patients who underwent tonsillectomy or adenotonsillectomy in the bivariate analysis (p = 0.217, 0.489, 0.512 respectively) and multiple regression model (p = 0.156, 0.802, 0.795) CONCLUSION: Dexmedetomidine does not negatively influence postoperative fluid intake levels in patients and should continue to be utilized in appropriately selected patients experiencing anxiety or agitation prior to surgery.

[About new possibilities for optimizing the postoperative period in tonsillectomy]. / O novykh vozmozhnostyakh optimizatsii postoperatsionnogo perioda pri tonzillektomii.

Tonsillectomy is one of the most frequent surgical interventions in otorhinolaryngology. This surgical is always accompanied by the development of reactive inflammatory phenomena and pain syndrome. The effectiveness and safety of tonsillectomy can be improved through the use of topical treatment in the postoperative period, including antiseptics in the form of a spray. An observational study was conducted at the Department of Otorhinolaryngology of the Russian University of Medicine of the Ministry of Health of the Russian Federation, the purpose of which was to evaluate the clinical efficacy, tolerability and safety of Viroxynol for oral and throat mucosa in patients after tonsillectomy. As a result of the analysis of the data obtained, it was found that the use of Viroxynol for the mucous membrane of the oral cavity and throat in the treatment of patients in the early postoperative period causes a pronounced clinical effect, reduces the need for additional medications, allows faster reduction of pain syndrome against the background of relief of reactive inflammatory phenomena, improves the quality of life of patients, accelerates the healing process, reduces the risk of bacterial inflammation. The drug may be recommended for use in patients after tonsillectomy.

Effects of dexamethasone on opioid consumption in pediatric tonsillectomy: a systematic review with meta-analysis.

PURPOSE: Tonsillectomy is one of the most common ambulatory procedures performed in children worldwide, with around 40,000 procedures performed in Canada every year. Although a prior systematic review indicated a clear role for dexamethasone as an analgesic adjunct, the quantity effect on opioid consumption is unknown. In the current systematic review with meta-analysis, we hypothesized that the use of dexamethasone reduces perioperative opioid consumption in pediatric tonsillectomy but does not increase rates of postoperative hemorrhage. SOURCE: We systemically searched MEDLINE, Embase, Cochrane Databases, and Web of Science from inception to 23 April 2024. Randomized controlled trials that compared intravenous dexamethasone to placebo in pediatric tonsillectomy were included in the study. The primary outcome was perioperative opioid consumption, and the secondary outcomes included the incidence of postoperative hemorrhage. We used a random effects meta-analysis to compute the mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI) for each outcome. PRINCIPAL FINDINGS: Of the 1,329 studies identified in the search, we included 16 in the final analysis. Intravenous dexamethasone administration significantly reduced opioid consumption (MD, -0.11 mg·kg-1 oral morphine equivalent; 95% CI, -0.22 to -0.01) without increasing the incidence of readmission (RR, 0.69; 95% CI, 0.28 to 1.67) or reoperation due to postoperative hemorrhage (RR, 3.67; 95% CI, 0.79 to 17.1). CONCLUSIONS: Intravenous dexamethasone reduced perioperative opioid consumption in pediatric tonsillectomy without increasing the incidence of postoperative hemorrhage.

RéSUMé: OBJECTIF: L'amygdalectomie est l'une des interventions ambulatoires les plus courantes chez les enfants dans le monde, avec environ 40 000 interventions réalisées au Canada chaque année. Bien qu'une revue systématique antérieure ait clairement indiqué le rôle de la dexaméthasone en tant qu'adjuvant analgésique, son effet quantitatif sur la consommation d'opioïdes est inconnu. Dans la présente revue systématique avec méta-analyse, nous avons émis l'hypothèse que l'utilisation de la dexaméthasone réduirait la consommation périopératoire d'opioïdes lors des cas d'amygdalectomie pédiatrique sans augmenter les taux d'hémorragie postopératoire. SOURCES: Nous avons effectué des recherches systématiques dans les bases de données MEDLINE, Embase, Cochrane et Web of Science depuis leur création jusqu'au 23 avril 2024. Nous avons inclus les études randomisées contrôlées comparant la dexaméthasone intraveineuse à un placebo dans les cas d'amygdalectomie pédiatrique. Le critère d'évaluation principal était la consommation périopératoire d'opioïdes, et les critères d'évaluation secondaires comprenaient l'incidence d'hémorragie postopératoire. Nous avons utilisé une méta-analyse à effets aléatoires pour calculer la différence moyenne (DM) ou le risque relatif (RR) avec un intervalle de confiance (IC) à 95 % pour chaque critère d'évaluation. CONSTATATIONS PRINCIPALES: Sur les 1329 études identifiées dans la recherche, nous en avons inclus 16 dans l'analyse finale. L'administration intraveineuse de dexaméthasone a permis de réduire significativement la consommation d'opioïdes (DM, −0,11 mg·kg−1 en équivalent oral de morphine; IC 95 %, −0,22 à −0,01) sans augmenter l'incidence de réadmission (RR, 0,69; IC 95 %, 0,28 à 1,67) ou de réopération due à une hémorragie postopératoire (RR, 3,67; IC à 95 %, 0,79 à 17,1). CONCLUSION: La dexaméthasone par voie intraveineuse a réduit la consommation périopératoire d'opioïdes dans les cas d'amygdalectomie pédiatrique, sans augmenter l'incidence d'hémorragie postopératoire.

Persistent Obstructive Sleep Apnea Post-adenotonsillectomy in Children.

Background Childhood obstructive sleep apnea (OSA) is a common disorder in children mostly due to adenotonsillar hypertrophy. Therefore, adenotonsillectomy is the mainstay of treatment. However, the outcome of adenotonsillectomy is limited in some patients who develop persistent OSA (POSA). We aim to evaluate the prevalence, risk factors, and treatments of POSA in the pediatric population in Qatar. Methodology This is a retrospective review of medical electronic records of patients aged 1-18 years, who underwent adenoidectomy and/or tonsillectomy at Sidra Medicine (Doha, Qatar) between June 2017 and September 2022. Demographic, clinical, and polysomnography (PSG) data were collected. POSA was defined as the persistence of at least one of the following OSA symptoms: snoring, gasping, mouth breathing or witnessed sleep apnea during post-surgery clinic visits, and/or post-surgical diagnosis of OSA by PSG. The prevalence of POSA was defined as the number of patients who had persistent symptoms divided by patients who were followed at outpatient clinics (ENT/pulmonology) post-surgery. Risk factors for POSA were evaluated using multivariate regression analysis. Results A total of 410 patients (259 males and 151 females) underwent adenotonsillectomy during the study period. The average age at surgery was 3.6 ± 2.5 years. The majority of patients (85.9%) had no history of underlying medical conditions. The rest of the patients (14.1%) were diagnosed with chromosomal abnormalities or neuromuscular disorders. All patients (100%) had a history of snoring before surgery, and 32.4% of patients had a history of witnessed sleep apnea. A total of 52 patients had persistent symptoms four months post-surgery. POSA prevalence was estimated at 15.4%. Univariate analysis showed young age at the time of surgery (p = 0.015), history of asthma (23%, 12/52) (p = 0.002), allergic rhinitis (13%, 7/52) (p = 0.001), gastroesophageal reflux disease ((11%, 6/52) (p < 0.001), and genetic syndromes (17%, 9/52) (p < 0.005) as significant risk factors for POSA. Multiple regression analysis showed that syndromic disorders and allergic rhinitis were significantly correlated with persistent OSA (p = 0.021 and p = 0.000, respectively). Conclusions POSA is prevalent in children post-tonsillectomy and adenoidectomy, especially in patients with genetic syndromes and those with symptoms of allergic rhinitis. Future studies are needed to better define the condition and provide evidence-based diagnostic and therapeutic approaches.

Risk of immediate postoperative fever in PFAPA patients undergoing tonsillectomy.

OBJECTIVE: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is the most common periodic fever syndrome in children. Tonsillectomy is considered a potential treatment option. A common concept is that patients with PFAPA are more likely to have postoperative fever, which might be hard to distinguish from other etiologies such as malignant hyperthermia or drug adverse effects. For this reason, many institutions require these patients to be cared for at their main center and not at satellite centers. Our objective was to evaluate the rate of immediate postoperative fever in PFAPA patients undergoing tonsillectomy. MATERIAL AND METHODS: Following IRB approval (STUDY20060029), a retrospective chart review of all PFAPA patients who underwent tonsillectomy at a tertiary children's hospital between January 1st, 2013, and September 30th, 2022. The PHIS database was queried from January 1st, 2013, to June 30th, 2022, for pediatric tonsillectomy and PFAPA. RESULTS: Sixty-one patients underwent tonsillectomy for PFAPA during the study period at our institution. Only one (1.6 %) had immediate postoperative fever. Fever episode resolution was seen in 90.25 % of patients, 41/41 (100 %) of the patients reported fever episodes pre-op, compared with 4/41 (9.75 %) post-op (McNemar's Chi-squared test, Chi2 = 37.0, p < 0.001). 481,118 pediatric tonsillectomies were recorded in the PHIS database during this period, 1197 (0.25 %) were also diagnosed with PFAPA. None of the PFAPA patients had an immediate post-operative fever. CONCLUSIONS: Our results suggest there is no increased risk of immediate postoperative fever in PFAPA patients undergoing tonsillectomy.

Malignant Abrikossoff's Tumour of the Tonsil - A Case Report of a Rare Entity.

Rationale: This study aimed to report an uncommon site of origin of a rare head-and-neck cancer, namely malignant granular cell tumour. Patient Concerns: An 89-year-old female patient complained of persistent pharyngodynia and odynophagia for two months. Diagnosis: Upon clinical examination, the right palatine tonsil was larger and palpably firmer than the contralateral. An incisional biopsy of the lesion was performed under local anaesthesia revealing malignant granular cell tumour. A contrast-enhanced computed tomography (CECT) scan of the head and neck and an 18F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) scan confirmed the presence of a pathologic appearance of the right palatine tonsil without nodal or distant metastasis. Treatment: Following a multidisciplinary consultation and the patient's informed permission, a right tonsillectomy extended to the constrictor muscle fibres of the upper pharynx was performed. Outcomes: The tumour was staged as pT2 R0 cN0 M0, according to the AJCC 8th edition for soft-tissue tumours of the head and neck. Due to the early stage and the radicality of surgery, no further adjuvant treatments were provided. The patient is currently followed up with no evidence of disease one year post-operatively. Take-away Lessons: Granular cell tumours are rare mesenchymal tumours, firstly described by the pathologist Abrikossoff in 1926. This type of tumour constitutes approximately 0.5% of all soft-tissue tumours, and can affect any part of the body, with the head and neck being the most frequently involved site. The tonsil is an extremely rare localisation of this cancer. The differential diagnosis of unilateral tonsillar enlargement should also include this histological entity.
