Tonsillectomy Research Articles

The Role of Transoral Robotic Palatine and Lingual Tonsillectomy in the Diagnosis of Carcinoma of Unknown Primary in the Head and Neck Region.

The use of transoral robotic surgery (TORS) lingual tonsillectomy in the diagnostic algorithm for head and neck carcinoma of unknown primary (CUP) has gained recent popularity. The primary aim of our study was to determine the identification rate of primary tumors in our cohort undergoing lingual ± palatine tonsillectomy for the workup of head and neck CUP. This was a retrospective study of all patients undergoing diagnostic TORS for head and neck CUP over an eight-year period, across four centers in two countries. Fifty-six patients undergoing TORS to aid diagnosis of a primary site were included. Overall, TORS lingual ± palatine tonsillectomy identified a primary tumor in 41 (73.2%) patients. Over half were T1 tumors, with 25% measuring under 10 mm. Among those with human papilloma virus (HPV)+ nodal disease, the identification rate was 82.6%. TORS lingual tonsillectomy is an effective addition to the diagnostic workup of CUP, particularly in those with HPV+ nodal disease.

Postoperative Complications in Lingual Versus Palatine Tonsillectomies.

The aim of this study was to investigate the risks of lingual tonsillectomy (LT) in a large cohort and compare these risks to those of palatine tonsillectomy (PT). A retrospective cohort study was conducted using data from the United States collaborative network within TriNetX. The LT group was defined using Current Procedural Terminology (CPT) code 42870 and PT group using CPT codes 42820, 42821, 42825, or 42826. Groups were further subdivided into pediatric and adult populations and matched based on propensity scores within the cohorts. Complications occurring within 14 days of procedure were compared within each cohort. There were 1,357 adult patients (mean age, 42.9 years) and 863 pediatric patients (mean age, 8.1 years). Adults who had LT were more likely to experience postoperative dysphagia (OR = 2.6, p < 0.001) and require admission to the hospital (OR = 4.3, p < 0.001) or intensive care unit (OR = 6.1, p < 0.001). There was no significant difference in bleeding between adult PT and LT groups, occurring at rates of 3.8% and 4.4%, respectively (p = 0.50). Pediatric patients who had LT were also more likely to experience postoperative dysphagia (OR = 2.4, p = 0.017) and require admission to the hospital (OR = 8.2, p < 0.001) or intensive care unit (OR = 2.7, p = 0.012). The postoperative bleed rate was 3.2% in the pediatric PT cohort, which was 2.4 times higher compared to those who underwent LT (1.5%, p = 0.016). Postoperative complications after lingual tonsillectomy are more common than after palatine tonsillectomy in both adults and children. III Laryngoscope, 2024.

Lingual Tonsillectomy as Part of a DISE-Directed Multilevel Upper Airway Surgery to Treat Complex Pediatric OSA: A Safe and Appropriate Procedure.

To study the efficiency of lingual tonsillectomy (LT) as part of multilevel surgery in children with complex obstructive sleep apnea (OSA). To evaluate the safety and the outcomes of LT. Retrospective case series. Pediatric tertiary care academic center. We included all children operated for LT to treat complex OSA, from January 2018 to June 2022. All patients underwent a protocolized drug-induced sleep endoscopy (DISE) followed by a coblation LT, associated with the treatment of all other obstructive sites. Patient demographics, medical history, surgery, and outcomes were reviewed. The efficiency of LT was analyzed exclusively in patients with a preoperative and postoperative sleep study. One hundred twenty-three patients were included. Median age was 8 years (interquartile range, IQR [3-12]). Sixty-five (53%) patients had Down syndrome, 22 (18%) had a craniofacial malformation, and 8 (7%) were obese. LT was associated with adenoidectomy (n = 78, 63%), partial tonsillectomy (n = 70, 57%), inferior turbinoplasty/turbinectomy (n = 59, 48%), epiglottoplasty (n = 92, 75%), and/or expansion pharyngoplasty (n = 2, 2%). Eighty-nine patients underwent a sleep study before and after surgery. The median apnea-hypopnea index (AHI) decreased from 18 events/h (IQR [9-36]) before surgery to 3 events/h (IQR [1-5]) after surgery (P < .001) (patients with a postoperative AHI <1.5 events/h, n = 31, 35%, and an AHI <5 events/h, n = 32, 36%). Seventeen out of 30 (57%) patients could be weaned from continuous positive airway pressure after surgery. Two patients had a postoperative hemorrhage and 2 patients required a transient postoperative reintubation. In children with complex OSA, LT as part of a DISE-directed multilevel upper airway surgery, was a very efficient and safe procedure.

Transoral Robotic Surgery Versus Hypoglossal Nerve Stimulation for OSA: A Cost Analysis Study.

Transoral robotic surgery (TORS) lingual tonsillectomy and hypoglossal nerve stimulation (HGNS) are effective surgical interventions for well-selected patients with obstructive sleep apnea (OSA) intolerant to continuous positive airway pressure (CPAP) therapy. Previous publications have demonstrated that HGNS patients have a lower postoperative apnea-hypopnea index (AHI) and length of hospital stay than TORS patients. No prior study has investigated the differences in costs between HGNS and TORS. This study aims to compare surgery-related costs in patients undergoing HGNS versus TORS lingual tonsillectomy for OSA intolerant to CPAP. A retrospective study on OSA patients intolerant to CPAP that underwent HGNS or TORS from 2015 to 2022 at a tertiary care center. Cost was defined as the dollar amount associated with providing a specific service prior to the application of insurance. This study included 395 patients (375 UAS and 20 TORS). Average total cost was significantly higher in the UAS group than the TORS group (UAS: $25,582.60; TORS: $5832.60; p < 0.001). Operating room costs were also significantly higher in the UAS group (UAS: $1978.20; TORS: $1490.90; p = 0.001). The TORS cohort averaged higher costs for pharmacy (UAS: $201.30; TORS: $416.60; p < 0.001) and anesthesia (UAS: $139.00; TORS: $307.60; p < 0.001). The total cost was significantly higher in the UAS group compared to the TORS group. When making management decisions, it is important to consider the cost of care provided as well as patient-centered outcomes to optimize the value of care. N/A Laryngoscope, 2024.

WPŁYW ADENOTONSILLEKTOMII NA KONTROLĘ ASTMY U PACJENTÓW PEDIATRYCZNYCH – PRZEGLĄD SYSTEMATYCZNY

IntroductionThis systematic review investigates the influence of adenotonsillectomy (AT) on asthma control in pediatric patients.Material and methodsA literature review from 2000 to 2023 based on the databases PubMed, the Cochrane Library, and Web of Science. The analysis is distilled down to four studies that revealed positive outcomes in asthma control as gauged by the Asthma Control Test (ACT), the Childhood Asthma Control Test (C-ACT), clinical outcomes, and asthma-related chitinase levels.ResultsThe four studies consistently demonstrated improved asthma control postoperatively in terms of improved ACT scores, reductions in acute asthma exacerbations, emergency room visits, hospitalisations, and medication usage. Notably, the correlation between improved asthma control and decreased chitinase activity suggests that AT has an impact on molecular markers associated with asthma.ConclusionsThe findings underline the potential benefits of AT in pediatric asthma management. However, the limitations of this study include a small number of studies and potential biases related to asthma’s natural course and seasonal variations. While the review provides evidence for the positive impact of AT on asthma control, further research with longer follow-up periods, case-matched controls, and consideration of seasonal factors is recommended.

Immunosuppression, tonsillectomy and remissions in high-risk IgA-nephropathy

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. 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. TE may be effective for remission induction in high-risk IgAN.

The impact of adenotonsillectomy on healthcare utilization in children with obstructive sleep apnea: Experience of an integrated medical model

Background and objectivesStudies suggest that children with obstructive sleep apnea (OSA) have increased healthcare utilization patterns in comparison to matched controls. However, the effect of adenotonsillectomy (AT) on utilization patterns in these children is poorly understood. Additionally, no previous studies have compared the effect of AT on healthcare utilization patterns across different OSA severity groups. The aim of this retrospective cohort study is to assess the effects of surgical treatment on the level of healthcare utilization among children with OSA at a large integrated multicenter healthcare system. MethodsRetrospective analysis was performed of children aged 3–12 diagnosed with OSA via an attended polysomnogram (PSG) between December 2016 and February 2019. Demographic variables including age (at time of PSG), body mass index (BMI), race, and ethnicity were obtained. Variables for healthcare utilization were assessed for 12 months prior to PSG, and for 12 months after PSG (or after AT, delayed for the first 30 days after surgery to account for surgery-related visits). Healthcare utilization variables assessed included the total number of outpatient visits, inpatient, and emergency department (ED) visits, visits involving diagnostic codes associated with upper respiratory infection (URI), otitis media (OM), and allergic rhinitis (AR), prescription data involving intranasal steroids or leukotriene receptor antagonists (LTRA), and communication data such as secure message load and specialty referrals. Repeated measure linear difference-in-difference (D-I-D) models were used to assess the causal impact of AT on healthcare utilization outcomes. Sensitivity analyses were performed using modeling with a Poisson distribution and as an unadjusted model, with statistical significance set to p < 0.05. ResultsAnalysis elicited 577 children identified with OSA. Of these, 336 (58.2 %) underwent observation while 241 (41.8 %) underwent AT. The mean age was 6.4 years, with a slight male predominance (60.5 %). Analysis of baseline healthcare utilization patterns revealed that the treatment group had a significantly higher number of baseline inpatient/ED visits and OM visits in comparison to the observation group, but no differences in regards to baseline outpatient visits, or in visits involving URI or AR.Analysis of the entire OSA cohort via D-I-D modelling showed a significantly larger reduction in outpatient visits, secure messages, specialty referrals, and the use of intranasal steroid and LTRA in the treatment group compared to the observation group. Stratification of children based on OSA severity showed that the significant differences in healthcare utilization attributed to surgical treatment were primarily driven by the severe OSA group. Children with severe OSA who underwent AT showed significant reductions in most variables including outpatient visits, inpatient/ED visits, and OM visits. Alternatively, the only significant reductions in healthcare utilization among children with mild OSA treated with AT were in AR visits, intranasal steroid use, and LTRA use. Pattern changes among children with moderate OSA compared similarly to those with mild OSA. ConclusionTo the authors’ knowledge this study represents the largest available study assessing the impact of AT on healthcare utilization in children with OSA that also considers the effect of OSA severity on utilization patterns. AT appears to decrease healthcare utilization patterns, particularly in children with severe OSA. Alternatively, children with mild or moderate OSA treated with AT had only modest reductions in healthcare utilization patterns.

Adenotonsillectomy Versus Watchful Waiting for Children with Obstructive Sleep Apnea Syndrome: A Systematic Review with Meta-Analysis

The treatment of children with Obstructive Sleep Apnea Syndrome (OSAS) remains a point of debate among otorhinolaryngologists worldwide. This study aims to comparatively assess the clinical outcomes of adenotonsillectomy (ATE) and watchful waiting in children with OSAS. We searched the databases of PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), until the 1st of October 2023. Comparative trials assessing the efficacy of adenotonsillectomy and watchful waiting in children with OSAS were considered. The primary outcome measure was the apnea-hypopnea index (AHI), and secondary outcomes included quality of life as measured by OSA-18 score, and mean SpO2 levels. A subgroup analysis evaluating the changes in AHI depending on the severity of the initial disease was also executed. We conducted a random-effects pairwise meta-analysis of change scores to include randomized and non-randomized controlled trials. The quality assessment was carried out by using the Cochrane risk of bias tool for randomized and the ROBINS-I tool for non-randomized trials, respectively. Two randomized and five non-randomized trials were included. There was a statistically significant difference regarding AHI in favor of the ATE group compared to the watchful waiting group (Standardized mean difference [SMD] was − 0.60, 95%CI −0.79 to −0.41, p < 0.001). Likewise, a statistically significant decrease in change scores for OSA-18 between ATE and watchful waiting was noted (SMD was − 0.79, 95%CI −0.97 to −0.61, p < 0.001). On the other hand, there was no significant difference when ATE and watchful waiting groups were compared for SpO2 levels between each other (SMD was 0.52, 95%CI −1.53 to 2.56, p < 0.62). In the subgroup analysis assessing mild OSAS, there was a significant difference in favor of ATE compared to watchful waiting (SMD was −0.91, 95%CI −1.35 to −0.47, p < 0.0001). For mild to moderate OSAS, similar results were noted favoring ATE as well (SMD was − 0.53, 95%CI −0.87 to −0.19, p < 0.003). This study provides evidence of moderate strength supporting the superiority of ATE over the watchful waiting approach in terms of AHI and OSA-18. This also appears to be the case for AHI in children with mild and mild to moderate OSAS.

Long Term Impact of Adeno-tonsillectomy on Immunity Against Respiratory Viral Infections; Evidence Deduced During COVID-19 Pandemic.

To evaluate the risk of acquiring COVID-19 infection in patients who have undergone adeno-tonsillectomy (AT) as compared to their siblings. In this bidirectional cohort control study, 36 cohorts, younger than 18 y, who underwent AT, and 27 controls (siblings of the enrolled cohorts, younger than 18 y) were recruited. Incidence of COVID-19 was analyzed by symptoms suggestive of COVID-19 infection, COVID-19 testing, and SARS-CoV-2 specific antibody measurement. In the cohort group, the overall COVID-19 positivity rate was 80.5% (n = 29/36) and symptomatic COVID-19 positivity rate was 68.9% (n = 20/29). Among the controls, the overall COVID-19 positivity rate was 44% (n = 12/27) and symptomatic COVID-19 positivity rate was 16% (n = 2/12). The cohorts had 1.8 times higher risk of contracting COVID-19 infection and the relative risk of symptomatic COVID-19 infections as compared to controls was 4.14. This pilot study indicates that adeno-tonsillectomy poses children at a significantly higher risk of COVID-19 infections and likely other viral upper respiratory tract infections.

Medicare volume and reimbursement trends in lingual and hyoid procedures for obstructive sleep apnea

ObjectivesThis study aims to analyze utilization and reimbursement trends in lingual and hyoid surgery for obstructive sleep apnea (OSA). MethodsAnnual retrospective data on lingual and hyoid OSA surgeries was obtained from the 2000–2021 Medicare Part B National Summary Datafiles. Current Procedural Terminology (CPT) codes utilized included 21,685 (hyoid myotomy and suspension [HMS]), 41,512 (tongue base suspension [TBS]), 41,530 (radiofrequency ablation of the tongue [RFT]) and 42,870 (lingual tonsillectomy [LT]). ResultsThe number of lingual and hyoid OSA surgeries rose 2777 % from 121 in 2000 to 3481 in 2015, before falling 82.9 % to 594 in 2021. Accordingly, Medicare payments rose 17,899 % from an inflation-adjusted $46,958 in 2000 to $8.45 million in 2015, before falling drastically to $341,011 in 2021. As the number of HMSs (2000: 91; 2015: 84; 2021: 165), TBS (2009: 48; 2015: 31; 2021: 16), and LTs (2000: 121; 2015: 261; 2021: 234) only experienced modest changes in utilization, this change was largely driven by RFT (2009: 340; 2015: 3105; 2021: 179). Average Medicare payments for RFT rose from $1110 in 2009 to $2994 in 2015, before falling drastically to $737 in 2021. ConclusionLingual and hyoid surgery for OSA has overall fallen in utilization among the Medicare population from 2000 to 2021. However, there was a brief spike in usage, peaking in 2015, driven by the adoption (and then quick dismissal) of RFT. The rise and fall in RFT use coincide with the rise and fall in reimbursement.

Obstructive Sleep Apnea and Mental Health Disorders in the Pediatric Population: A Retrospective, Population-based Cohort Study.

Rationale: Information is limited about the association between obstructive sleep apnea (OSA) and mental health disorders in children. Objectives: In children, 1) to evaluate the association between OSA and new mental healthcare encounters; and 2) to compare mental healthcare encounters 2 years after to 2 years before OSA treatment initiation. Methods: We conducted a retrospective longitudinal cohort study using Ontario health administrative data (Canada). Children (0-18 yr) who underwent diagnostic polysomnography (PSG) 2009-2016 and met criteria for definition of moderate-severe OSA (PSG-OSA) were propensity score weighted by baseline characteristics and compared with children who underwent PSG in the same period but did not meet the OSA definition (PSG-No-OSA). Children were followed until March 2021. Weighted cause-specific Cox proportional hazards and modified Poisson regression models were used to compare time from PSG to first mental healthcare encounter and frequency of new mental healthcare encounters per person time, respectively. Among those who underwent adenotonsillectomy (AT) or were prescribed and claimed positive airway pressure therapy (PAP), we used age-adjusted conditional logistic regression models to compare 2 years post-treatment to pretreatment odds of mental healthcare encounters. Results: Of 32,791 children analyzed, 7,724 (23.6%) children met criteria for moderate-severe OSA. In the PSG-OSA group, 7,080 (91.7%) were treated (AT or PAP). Compared with PSG-No-OSA, the PSG-OSA group had a shorter time from PSG to first mental healthcare encounter (hazard ratio, 1.08; 95% confidence interval [CI], 1.05-1.12) but less frequent mental healthcare encounters in follow-up (rate ratio, 0.92; 95% CI, 0.87-0.97). OSA treatment (AT or PAP) was associated with lower odds of mental healthcare encounters 2 years after treatment initiation compared with 2 years before (odds ratio, 0.69; 95% CI, 0.65-0.74). Conclusions: In this large, population-based study of children who underwent PSG for sleep disorder assessment, OSA diagnosis/treatment was associated with an improvement in some mental health indicators, such as fewer new mental healthcare encounters compared with no OSA and lower odds of mental healthcare encounters compared with before OSA treatment.

A prospective cohort study: The effects of preoperative E-health on the postoperative course of tonsillectomy patients

PurposeAt our clinic, a significant portion of tonsillectomy (TE) preoperative assessments are conducted remotely. The aim of our study was to examine the variation in TE complications, contact rates, and reasons for patient contact between those evaluated preoperatively at the outpatient clinic (OPC), or remotely through virtual visits (VV), or via a digital care pathway (DCP). This investigation is critical for optimizing patient flow through the volume-intensive process of TE. MethodsWe conducted a prospective cohort study involving 422 patients who underwent TE at Helsinki University Hospital ENT clinic to investigate their 30-day postoperative course. We extracted information on postoperative contacts, complications, and demographic data. Postoperative contact rate was the primary outcome measure to evaluate whether telehealth patients suffered fewer postoperative issues. ResultsPatients from the OPC were least likely to seek medical assistance in the 30-day postoperative period. However, no significant difference was discovered compared to the remotely assessed DCP patients, and over entire TE episodes, the DCP patients had the fewest unplanned contacts compared to the VV and OPC cohorts. Furthermore, the care paths shared similar complication and contact method profiles with comparable post-tonsillectomy hemorrhage incidence. ConclusionA preoperative DCP for TE appeared to carry similar postoperative contact and complication rates, as well as comparable contact method profiles compared to the OPC model. Given the high patient satisfaction and cost-consciousness associated with the DCP, our findings encourage a broader implementation of highly developed DCPs in preoperative assessment for TE.

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 4h. 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 15min and 1h 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 byH.pyloriis 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.

Surgical Management of Pediatric Obstructive Sleep Apnea Beyond T&A – Tongue Base and Larynx

Pediatric patients with persistent obstructive sleep apnea (OSA) after adenotonsillectomy often have additional sites of upper airway obstruction such as the tongue base or larynx. Sleep endoscopy and cross-sectional, dynamic imaging can be used to direct the surgical management of persistent OSA. The tongue base is one of the most common sites of obstruction in children with persistent OSA, especially for patients with Trisomy 21. Lingual tonsillectomy, tongue suspension, and/or posterior midline glossectomy may be used to address lingual tonsil hypertrophy and tongue base obstruction. Epiglottopexy and/or supraglottoplasty may be used to address laryngomalacia and epiglottic prolapse resulting in OSA. Evidence shows that surgery can lead to significant improvement in postoperative polysomnographic outcomes. Important considerations following surgery of the tongue base and larynx include bleeding, edema, oropharyngeal stenosis, and dysphagia.

Narrative review in learning curve and pediatric robotic training program.

Studying learning curve (LC) for robotic procedures and developing an adequate training program are two fundamental steps to standardize robotic procedures. With this aim, we analyzed the literature to study the LCs of different robotic procedures and the availability of standardized training problems. The PubMed database was searched in the period from January 1995 to September 2022. Articles presenting LC and potential training programs in the pediatric population were chosen. Twenty papers were screened describing LC of robotic-assisted laparoscopic pyeloplasty (n=12), fundoplication (n=4), cholecystectomy (n=2), choledochal cyst resection (n=1), nephrectomy/partial nephrectomy (n=1) and lingual tonsillectomy (n=1), with a total of 1,251 procedures. In 10 studies there was only one single surgeon; nine had more than one; one did not specify how many surgeons participated. Twelve papers were retrospective single-center, three multicentric retrospective, four prospective and one was compared a retrospective case series to a prospective cohort. Most of these studies focused on operative time as the primary outcome. It was analyzed as the only outcome in three articles, along with complications in 14, time to discharge in eight, blood loss in three and pain killer use in three. The selected studies analyzed LC impacting operative planning (n=20), training (n=10) and costs (n=2). There is still a long way to go to complete a standardized functional training for robotic surgery procedures in pediatric surgery. Moreover, the progressive reduction in costs expected in the years to come will play a key role in progressing the diffusion of this technology enabling the collection of data necessary to create a standardized pediatric surgery robotic training program.

Long-term effects of adenotonsillectomy in children with attention deficit hyperactivity disorder.

Adenotonsillectomy (AT) improves short-term symptoms of attention deficit hyperactivity disorder (ADHD) in children; however, its long-term effects remain unclear. We aimed to verify the therapeutic long-term effects of AT in children with ADHD. This retrospective control study included children ages < 18 years who were diagnosed with ADHD and receiving ADHD medications. Participants were divided into groups depending on whether AT was performed (AT [+] or AT [-] groups) and matched 1:1 for age, sex, and year and month of diagnosis using randomized nonreplacement selection. Among patients with ADHD (n = 171,112), 3,615 underwent AT. In both groups, the number of drugs taken gradually increased before and decreased after the AT date (ATD). There was no difference in the number of drugs used before (P = .88) and after ATD (P = .06). Before ATD, the average number of outpatient visits (nOV) did not change in both groups (AT [+]: P = .12; AT [-]: P = .71). After ATD, the average number of outpatient visits decreased only in the AT (+) group (P = .001). However, there was no difference in the average number of outpatient visits between the two groups before (P = .47) and after ATD (P = .17). Before ATD, methylphenidate doses between the groups were not different (P = .06); however, a significant increase was noted after ATD in the AT (+) group (P < .001). AT does not result in significant long-term therapeutic effects in terms of medication use and health care utilization in children with ADHD. Lee J, Choi A, Kim S, Kim K.

Alterations of Gut Microbiome Composition and Function Pre- and Post-Adenotonsillectomy in Children with Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) in children is linked with alterations in the gut microbiome. The influence of adenotonsillectomy (AT), a primary intervention for OSA, on gut microbiota dynamics relative to disease severity remains to be elucidated. This study aimed to investigate the impact of OSA severity and AT on the gut microbiome in pediatric patients. A prospective observational study. Tertiary referral center. A cohort of 55 pediatric patients treated with AT for OSA. Total tonsillectomy and adenoidectomy procedures. Comprehensive evaluations included in-laboratory polysomnography and 16S rRNA gut microbiome profiling at baseline, and again at 3rd and 12thmonth following surgery. Initial findings showed uniform α-diversity across different severities of OSA, while β-diversity was significantly elevated in the severe OSA subgroup. Certain gut microbiota taxa (Lachnospiraceae NK4A136 group, Ruminococcaceae UCG-002, Ruminococcaceae UCG-014, Alloprevotella, Christensenellaceae R-7 group, Ruminococcaceae UCG-005, Lactobacillus murinus, and Prevotella nigrescens) were found to inversely correlate with the apnea-hypopnea index (AHI). Significant post-AT improvements in AHI and other polysomnographic metrics were observed. Notably, AHI changes post-AT were positively associated with microbial α-diversity (species richness), β-diversity, and specific bacterial taxa (Enterobacter, Parasutterella, Akkermansia, Roseburia, and Bacteroides plebeius DSM 17135), but negatively with other taxa (Fusicatenibacter, Bifidobacterium, UBA1819, Ruminococcus gnavus group, Bifidobacterium longum subsp. Longum, and Parabacteroides distasonis) and specific metabolic pathways (purine metabolism, transcription factors, and type II diabetes mellitus). The postoperative patterns of α- and β-diversity mirrored baseline values. This study documents significant changes in the gut microbiome of pediatric patients after AT, including variations in α- and β-diversities, bacterial communities, and inferred metabolic functions. These changes suggest a potential association between the surgical intervention and microbiome alterations, although further studies are necessary to discern the specific contributions of AT amidst possible confounding factors such as antibiotic use.

Comparison of intravenous ibuprofen and paracetamol for peri-operative analgesia in paediatric day care tonsillectomy.

To determine the effectiveness of intravenous ibuprofen and acetaminophen as perioperative analgesics in paediatric patients undergoing day- care tonsillectomy with general anaesthesia. The quasi-experimental stud y was conduc ted at the Ana esthe sia D epartment of Pa k Emirates M ilitary Hospital, Rawalpindi , Pak ist an, from July 20 21 to June 2022, and comp rised paediatric pa t ients aged 5-12 yea r s undergoing day- care tonsil lec tomy with gen era l anaesthesia. The sub jec ts were divid ed into two equa l groups. Patients in Group I received intravenous ibuprofen 7mg/kg and patients in Group P received intravenous paracetamol 10mg/kg im media t ely after induction of anaesthesi a. All patients recei ved standard general anaesthesia with endotracheal intubation. The primary outcome measured was revised faces pain score immediately after recovery and at the time of discharge 6 hours later. Adverse events were also noted. Data was analysed using SPSS 26. Of the 100 patients, there were 50(50%) in Group I; 21(42%) boys and 29(58%) girls with mean age 7.82±1.903 years. The remaining 50(50%) subjects were in Group P; 25(50%) boys and 25(50%) girls with mean age 7.68±1.812 years. At baseline, 44(88%) patients in Group I and 42(84%) in Group P reported no pain, while 6(12%) and 8(16%) patients in the two groups, respectively, reported pain (p=0.56). At discharge, 35(70%) patients in Group I and 18(36%) in Group P reported no pain (p<0.001). Adverse events were not significantly different between the groups (p>0.05). I ntravenous ibuprofen was found to b e a superior pain-killer than intravenous paracetamol for perioperative care of paediatric patients in day- care tonsillectomy.

Clinical case of laser ablation of lingual amygdala

Hypertrophy of the lingual tonsil is a condition in which the lingual tonsil, located at the base of the tongue, enlarges. This tonsil consists of clusters of follicles separated by a central groove. In children under 5 years old, the number of follicles usually ranges from 10 to 12, while in adults up to 40 years old, it can reach 35 to 40. This structure plays an important role in the immune system, helping the body fight infections and microbes. Like other tonsils in the throat, the lingual tonsil can sometimes cause problems, such as hypertrophy (enlargement) or chronic infections. The causes of lingual tonsil hypertrophy can be diverse. In some cases, it develops as a compensatory process after the removal of the palatine tonsils. The primary cause in adults may be chronic inflammation of the pharynx. Severe degrees of lingual tonsil hypertrophy are very rare but can lead to various symptoms, such as coughing, difficulty swallowing and breathing, a feeling of pressure in the area beneath the tongue, and other nonspecific complaints. These symptoms are not pathognomonic for lingual tonsil hypertrophy. The challenges in diagnosis and the lack of a standardized approach to surgical treatment require detailed consideration and description in each individual case. Sometimes, patients with lingual tonsil hypertrophy complain of coughing paroxysms. In such cases, mechanical irritation of the lingual tonsil with a probe can provide some assistance in diagnosis. In the context of this study, lingual tonsillectomy surgery was performed on a patient using a diode laser. The results obtained confirmed the high level of technological feasibility and appropriateness of using laser ablation for the treatment of lingual tonsil hypertrophy. Laser ablation is one of the possible surgical procedures for treating lingual tonsil hypertrophy. It can be an effective and technologically advanced method, although it requires experience and qualification of specialists.
