The safety and efficacy of powered intracapsular tonsillectomy in children: A meta-analysis

Tonsillectomy Versus Tonsillotomy in Pediatric Sleep-Disordered Breathing: A Systematic Review and Multi-subgroup Meta-analysis

OBJECTIVES

To evaluate the potential of tonsillotomy (TT) as an alternative to tonsillectomy (TE) for treating children with obstructive sleep-disordered breathing (oSDB).

DATA SOURCES

Two independent reviewers searched PubMed, the Cochrane Library, Embase, and additional sources to identify controlled studies comparing TT versus TE in pediatric patients with oSDB.

REVIEW METHODS

We evaluated post-surgery symptom relief, and short- and long-term postoperative benefits for children. Fixed-effect meta-analysis, sensitivity analysis, and subgroup analysis were conducted.

RESULTS

In our analysis of 32 studies with 9,430 children, the analysis revealed TT group had a similar therapeutic effect on improvement of OSA-18 as TE group (MD = 5.20, 95% CI: -32.67 to 43.07, p = 0.96). In terms of short-term outcome, the days to return to normal diet for TT group were shorter than that for TE group (MD = -2.49, 95%CI: -3.57 to -1.28; p < 0.001), less analgesics use (MD = -3.19, 95% CI = -3.44 to -2.93, p < 0.001), and lower postoperative secondary bleeding (RR = 0.33; 95%CI: 0.23 to 0.47; p < 0.001). But the risk of reoperation (OR = 8.28; 95%CI: 2.66 to 12.64; p < 0.001), oSDB recurrence (OR = 2.16; 95%CI: 1.20-3.86; p = 0.01), and postoperative infection (OR = 1.82; 95%CI: 1.34 to 2.47; p < 0.001) in TT group was significantly higher than that in TE group.

CONCLUSIONS

Tonsillotomy reduces postoperative pain and bleeding, speeding up recovery for children with oSDB, and improving their quality of life. Yet, the risk of recurrent infections from residual tonsil tissue, which may require reoperation, calls for a careful evaluation of the procedure's short-term gains against its long-term risks.

Intracapsular Versus Total Tonsillectomy in Patients with Trisomy 21

OBJECTIVES

Intracapsular tonsillectomy and adenoidectomy (iTA) has become a popular alternative to extracapsular tonsillectomy and adenoidectomy (TT) for the treatment of pediatric obstructive sleep apnea (OSA) due to improved recovery and fewer complications. The objective of this study was to compare surgical recovery and impact on OSA of iTA versus TT in patients with Trisomy 21 (T21).

METHODS

This is a case series with chart review of all T21 patients who underwent iTA or TT at our institution between July 1, 2015 and August 15, 2022. Data collected included demographics, comorbidities, preoperative sleep studies, intraoperative data, complications and recovery, postoperative sleep studies, and follow-up data.

RESULTS

There were 62 (21.7%) patients who underwent iTA and 224 (78.3%) patients who underwent TT. The iTA group had significantly lower pain scores (p < 0.001), decreased use of narcotics (p < 0.001), shorter length of stay (p = 0.003), and faster return to oral intake (p = 0.01) during their postoperative hospital admission, and fewer 30-day complications (p = 0.009) compared to the TA group. Both groups showed significant improvements in their sleep studies. For 41 (66.1%) of iTA patients who had follow-up, median follow-up was 1.8 years and for 169 (75.4%) TT patients, median follow-up was 2.6 years. At follow-up, 21 of 41 (51.2%) iTA patients and 83 of 169 (49.1%) TT patients exhibited OSA symptoms (p = 0.084) and tonsillar regrowth was not significantly different between the two groups (p = 0.12).

CONCLUSION

Patients with T21 experience less pain and fewer postoperative respiratory complications from iTA than from TT. The short-term impact of iTA versus TT on OSA, as measured by poysomnography, does not differ between the two techniques.

Postoperative Morbidity of Different Tonsillectomy Techniques: A Systematic Review and Network Meta-Analysis

OBJECTIVE

To compare different tonsillectomy techniques in terms of postoperative bleeding incidence and postoperative pain.

METHODS

An arm-based network analysis was conducted using a Bayesian hierarchical model. The primary and secondary outcomes were postoperative bleeding incidence and mean postoperative pain score.

RESULTS

A total of 6464 patients were included for five different interventions (cold dissection tonsillectomy; extracapsular coblation tonsillectomy; intracapsular coblation tonsillectomy [ICT]; bipolar diathermy tonsillectomy [BDT]; monopolar diathermy tonsillectomy). ICT showed the lowest absolute risk (4.44%) of postoperative bleeding incidence (73.31% chance of ranking first) and the lowest mean postoperative pain score (1.74 ± 0.68) with a 94.0% chance of ranking first, whereas BDT showed both the highest absolute risk of bleeding incidence (10.75%) and the highest mean postoperative pain score (5.67 ± 1.43).

CONCLUSIONS

ICT seems to offer better postoperative outcomes, in terms of reduced risk of bleeding and reduced pain. Further prospective studies are advised to confirm these findings.

Postoperative Outcomes of Intracapsular Tonsillectomy With Coblation: A Systematic Review and Meta-Analysis

OBJECTIVE

Following tonsillectomy, postoperative pain and hemorrhage from the tonsillar bed are causes of significant morbidity. Intracapsular tonsillectomy with Coblation is suggested to minimize such morbidity while remaining efficacious in long-term outcomes. This systematic review and meta-analysis assessed short-term morbidity and long-term outcomes from intracapsular tonsillectomy with Coblation, focusing primarily on posttonsillectomy hemorrhage.

DATA SOURCES

Medline, Embase, and the Cochrane Library.

REVIEW METHODS

Guided by PRISMA guidelines, studies on intracapsular tonsillectomy with Coblation published between December 2002 and July 2022 evaluating frequency of posttonsillectomy hemorrhage were screened. Studies without primary data were excluded. Meta-analysis was conducted using the random-effect model. The primary outcome was the proportion of patients who experienced posttonsillectomy hemorrhage. The secondary outcomes were posttonsillectomy pain, the proportion requiring revision tonsillectomy, and severity of sleep-disordered breathing measured by polysomnography outcomes.

RESULTS

From 14 studies there were 9821 patients. The proportion of total posttonsillectomy hemorrhage was 1.0% (95% confidence interval [CI] 0.5%-1.6%, n = 9821). The proportion experiencing primary hemorrhage, secondary hemorrhage, and those requiring further tonsil surgery were 0.1% (95% CI 0.0%-0.1%; study n = 7), 0.8% (95% CI 0.2%-1.4%; study n = 7), and 1.4% (95% CI 0.6%-2.2%; study n = 6), respectively. Mean reduction in apnea-hypopnea index was -16.0 events per hour (95% CI -8.8 to -23.3, study n = 3) and mean increase in oxygen nadir was 5.9% (95% CI 2.6%-9.1%, study n = 3).

CONCLUSION

Intracapsular tonsillectomy with Coblation has been demonstrated to have a low rate of posttonsillectomy hemorrhage. Data regarding long-term tonsil regrowth and need for reoperation were encouraging of the efficacy of this technique.

Reconsidering routine admission for children under age 3 undergoing partial tonsillectomy: a prospective study

BACKGROUND

Partial Tonsillectomy (PT) is an alternative method to treat sleep disordered breathing (SDB) and/or obstructive sleep apnea (OSA). The current guidelines do not differentiate it from traditional tonsillectomy. Thus, children younger than 3 years old undergoing PT are admitted for surveillance similar to traditional tonsillectomy due to possible postoperative complications. The aim of this study is to assess the risks of PT in children 3 years old and younger, compared to older children.

METHODS

Children underwent inpatient partial tonsillectomy and/or adenoidectomy, due to SDB/OSA, from 2018 to 2020. A special protocol was designed, including follow-up at 2-, 4-, 6-, 8- and 24-h after surgery. Variables analyzed included visual analogue pain score, oral intake, oxygen saturation, pulse rate, postoperative hemorrhage, urine output, temperature, analgesics and fluid administration. Furthermore, major interventions were recorded. Comparison of all variables between children younger than 3 years old with older children was performed.

RESULTS

Ninety-two children were included; mean age of the whole cohort was 44.5 ± 21.9 months. Thirty-five (38%) children were 3-years old or younger and n = 57 (62%) were older than 3 years old, with no significant statistical difference in sex (p = 0.22). Mean age in the younger group was 25.7 ± 6.9 months, and 56.1 ± 20.1 months in the older group. In total we had 7 children with post-operative complications; 4 with fever, 3 with low intake. There were no major interventions recorded in either group. The complications were more common in the older group (n = 5) than the younger group (n = 2) without a statistical significance (p = 0.59). There were no differences in VAS, use of painkillers, oral intake, urine output, oxygen saturation and tachycardia among the two groups.

CONCLUSION

This study supports that children undergoing ambulatory PT may be at low risk of complications, regardless of age.

Powered Intracapsular Tonsillotomy and Adenoidectomy in Infants ≤36 Months Compared to Older Children: A Retrospective Analysis

OBJECTIVES

To evaluate the safety and outcomes of powered intracapsular tonsillotomy and adenoidectomy (PITA) for the treatment of sleep disordered breathing in infants up to 36 months of age compared to older children.

METHODS

This retrospective analysis included children who underwent PITA from 2013 to 2019 at a single tertiary care medical center. The patients were divided into 2 groups: up to 36 months, and 36 to 72 months. The data were collected from electronic medical records and from a telephone survey based on a modified version of the OSA-18 questionnaire. Post-operative complications, and short- and long-term outcomes were compared.

RESULTS

A total of 48 patients met the inclusion criteria for the main study group (up to 36 months of age). They were compared to 59 children 36 to 72 months of age. There were no differences in subjective outcomes between age groups (P = .65). There were no differences in the frequency of post-operative complications between age groups (P = .8) or in the number of hospitalization days (P = .91).

CONCLUSION

The short- and long-term outcomes and safety of PITA for the treatment of sleep disordered breathing in infants up to 36 months of age are similar to those of older children.

Intracapsular tonsillectomy in the treatment of recurrent and chronic tonsillitis in adults: a protocol of a prospective, single-blinded, randomised study with a 5-year follow-up (the FINITE trial)

INTRODUCTION

The standard surgical treatment for recurrent or chronic tonsillitis is extracapsular tonsillectomy. Recent studies show that intracapsular tonsillectomy has the potential to reduce the postoperative morbidity of patients undergoing tonsil surgery. The Finnish Intracapsular Tonsillectomy (FINITE) trial aims to provide level I evidence to support the hypothesis that the recovery time from tonsil surgery can be reduced with intracapsular tonsillectomy. Additionally, from this trial, major benefits in quality of life, reduction of postoperative complications, treatment costs and throat symptoms might be gained.

METHODS AND ANALYSIS

The FINITE trial is a prospective, randomised, controlled, patient-blinded, three-arm clinical trial. It is designed to compare three different surgical methods being extracapsular monopolar tonsillectomy versus intracapsular microdebrider tonsillectomy versus intracapsular coblation tonsillectomy in the treatment of adult patients (16-65 years) suffering from recurrent or chronic tonsillitis. The study started in September 2019, and patients will be enrolled until a maximum of 200 patients are randomised. Currently, we are in the middle of the study with 125 patients enrolled as of 28 February 2022 and data collection is scheduled to be completed totally by December 2027. The primary endpoint of the study will be the recovery time from surgery. Secondary endpoints will be the postoperative pain scores and the use of analgesics during the first 3 weeks of recovery, postoperative haemorrhage, quality of life, tonsillar remnants, need for revision surgery, throat symptoms, treatment costs and sick leave. A follow-up by a questionnaire at 1-21 days and at 1, 6, 24 and 60 months will be conducted with a follow-up visit at the 6-month time point.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Medical Ethics Committee of the Hospital District of Southwest Finland (reference number 29/1801/2019). Results will be made publicly available in peer-reviewed scientific journals.

Safety and long-term efficacy of tonsillectomy versus subtotal tonsillectomy in children with sleep disordered breathing

OBJECTIVES

to compare safety and long-term symptoms after TE compared to Subtotal Tonsillectomy (STT).

METHODS

A retrospective review data of 412 patients, one to twelve years old that underwent either TE or STT, as treatment for sleep disorder breathing, at two different medical centers. Symptoms were assessed by a questionnaire 3-5 years post-surgery. Additionally, data regarding immediate post-operative symptoms and complications were also collected.

RESULTS

Long-term symptoms score was significantly lower in the TE group: 1.585 (±1.719) compared to 1.967 (±1.815) in the STT group (p = 0.033); 51.3% of patients in the ST group presented long-term SDB symptoms, compared to 40.6% in the TE group (p = 0.035); The main difference between the groups was snoring as 49% of the STT group suffered from snoring, versus 28.9% in the TE group (p < 0.001).

CONCLUSIONS

TE showed an advantage over STT in resolving snoring in the long term.

A prospective, randomized, single-blind study comparing coblation and monopolar extracapsular tonsillectomy

Objective

The aim of this study was to compare intraoperative blood loss, postoperative pain, post-tonsillectomy hemorrhage (PTH), and medical costs associated with extracapsular tonsillectomy between coblation and monopolar electrocautery in children.

Materials and methods

This study included 293 patients aged 6-15 years planned to undergo extracapsular tonsillectomy. Data on estimated blood loss, postoperative pain score, operation time, PTH, and the cost of disposable equipment were collected.

Results

Coblation extracapsular tonsillectomy was associated with significantly lower mean pain scores than monopolar technique on postoperative days 1 (p <.001) and 2 (p = 0.02). However, the pain score was similar between the groups at all other time points. The monopolar group had a significantly shorter operation time compared to the coblation group (11.09 ± 7.53 vs. 17.12 ± 4.29 min, p <.001). Intraoperative estimated blood loss was not significantly different between the groups (p = .43).The cost of extracapsular tonsillectomy was significantly lower in the monopolar compared to the coblation group (US$ 28.18 vs. US$ 430.48, p <.001). PTH occurred in 17 patients (5.80%) and required a second surgery. Secondary PTH occurred in 6.16% (9/146) and 0.68% (1/147) of patients in the coblation and monopolar groups, respectively (p <.001). The PTH was significantly higher in the tonsillitis compared to in the tonsillar hypertrophy (12.37% vs. 2.55%, p = .002), However, the difference of PTH was not significant among mean pain scores subgroups. Of the 17 patients with PTH, the lower pole, middle portion, and upper pole were involved in 15 (88.24%), 2 (11.76%), and 0 cases, respectively.

Conclusions

Coblation and novel monopolar electrocautery extracapsular tonsillectomy are associated with similar postoperative pain scores except on postoperative days 1 and 2. However, monopolar technique offers significant advantages over coblation method with less operative time, decreased secondary PTH, and cost.Level of Evidence: NA.

Tonsillectomy and Adenoidectomy - Pediatric Clinics of North America

Tonsillectomy and adenoidectomy are among the most commonly performed major pediatric operations in the United States, with more than 500,000 procedures performed annually. This procedure can be performed with or without adenoidectomy. These procedures were traditionally performed for recurrent tonsillitis; however, the vast majority of tonsillectomies are currently performed for obstructive symptoms. When performed for appropriate indications, tonsillectomy and adenoidectomy can greatly improve a child's quality of life and general health. Given the prevalence of these conditions and subsequent surgical procedures, evidence-based recommendations are regularly evaluated and updated. As such, familiarity with these guidelines is necessary for pediatric practitioners. This review summarizes the indications, complications, and outcomes for tonsillectomy and adenoidectomy, as well as provides a brief overview of operative techniques.

Effect of intravascular dexamethasone injection after powered intracapsular tonsillectomy and adenoidectomy in children

PURPOSE

To compare postoperative pain, nausea and vomiting, and bleeding between intravascular dexamethasone injection group and control group among children undergoing powered intracapsular tonsillectomy and adenoidectomy (PITA).

MATERIALS AND METHODS

Retrospective review of medical records was performed for pediatric patients who underwent PITA from March 1, 2017, to February 28, 2021, at a tertiary referral medical center in South Korea. Postoperative pain and nausea were measured using the visual analogue scale (VAS) from the postoperative day (POD) 0 to POD 6. The number of analgesics administered and the number of vomiting episodes were recorded in the same period. The repeatedly measured parameters were statistically analyzed between the dexamethasone group and control group.

RESULTS

A total of 71 children with complete questionnaires including 44 boys and 27 girls were included, and the mean age was 7.49 ± 2.44 years. There were 33 patients in the dexamethasone group and 38 in the control group. Postoperative pain (p = 0.169) or nausea (p = 0.460) on the VAS showed no statistically significant difference between the two groups. Postoperative analgesics showed no difference between the groups (p = 0.398), and neither did postoperative vomiting (p = 0.270). In both groups, no child showed signs of postoperative bleeding.

CONCLUSIONS

This study indicates that the beneficial effects of intravascular dexamethasone administration in PITA may not be evident. This might be due to the superior outcome of the PITA technique compared to total extracapsular tonsillectomy. Therefore, otolaryngologists performing PITA may not necessarily need to administer dexamethasone in children before surgery.

Comparison of short-term recovery in children with obstructive sleep apnea undergoing tonsillotomy vs. tonsillectomy

OBJECTIVES

To compare the pain levels, degrees of pharyngeal swelling, and weight loss after tonsillectomy vs. tonsillotomy in children clinically diagnosed with obstructive sleep apnea (OSA) over the first seven postoperative days, and to determine which procedure was associated with better recovery in the early postoperative period.

METHODS

Between April 2021 and December 2021, 121 children with OSA (80 males and 41 females), ranging from 3 to 12 years of age with an average age of 6.7 years, were prospectively enrolled in this study conducted at Zhengzhou Central Hospital Affiliated to Zhengzhou University. The patients were randomly divided into two groups: a tonsillotomy group with 63 cases (40 males and 23 females) and a tonsillectomy group with 58 cases (40 males and 18 females). The patients' pain levels [as indicated by Parents' Postoperative Pain Measure (PPPM) scores] and degrees of pharyngeal swelling were recorded for seven days postoperatively, and the patients' body weights were recorded on postoperative day seven.

RESULTS

In the tonsillotomy group, the PPPM scores were the highest on the day of surgery and on the first postoperative day; the patients' pain levels gradually decreased.The PPPM scores in the tonsillectomy group were higher than those in the tonsillotomy group from the day of surgery to the seventh postoperative day (p < 0.05). The degree of pharyngeal swelling was lower in the tonsillotomy group than in the tonsillectomy group. Weight loss was lower in the tonsillotomy group than in tonsillectomy group on the 7th day after surgery (p < 0.05). On the fifth, sixth, and seventh postoperative days, compared with preschool children, school-age children who had undergone tonsillotomy experienced more pain relief than those who had undergone tonsillectomy (p < 0.05).

CONCLUSION

Children with OSA experienced less pain, less pharyngeal swelling, and less weight loss with tonsillotomy than with tonsillectomy. On the fifth, sixth, and seventh postoperative days, compared with preschool children, tonsillotomy in school-age children is more advantageous in school-age children.

Extracapsular versus intracapsular tonsillectomy: Outcomes in children with a focus on developmental delay

INTRODUCTION

Outcomes following intracapsular tonsillectomy (IT) have not been well established in children with developmental delays. The objective of this study was to compare outcomes and complications between intracapsular and extracapsular tonsillectomy (TT) in pediatric patients with developmental delay (DD) in comparison to non-developmentally delayed children.

METHODS

This is a retrospective study of pediatric patients with DD undergoing tonsillectomy between 2016 and 2019 at a tertiary care hospital. This group included patients with Down Syndrome, Autism Spectrum Disorder, other genetic syndromes, and patients with a diagnosis of global developmental delay. Outcomes and complications were analyzed for IT and TT.

RESULTS

2267 charts were reviewed, and 320 patients were identified with DD. Of those, 72 patients underwent IT and 248 underwent TT. In the DD cohort, the IT group had a shorter length of stay (0.97 vs 1.7 days, p < .0001) and was less likely to receive post-operative narcotic medication (2.8% vs 35%, p < .0001) and corticosteroids (9.7% vs 64%, p < .0001) during their hospital stay. Reductions in emergency room (ER) visits (5.6% vs 10%, p = .21) and post-op bleeding (PTH) (1.4% vs 4.8%, p = .31) for IT vs TT were not statistically significant in the DD group. In the NDD group, fewer patients undergoing IT returned to the ER (11% vs 2.3%, p < .0001) or had PTH (4.8% vs 0.25%, p, 0.0001) as compared to those children undergoing TT. There was no difference between parental report of symptom improvement between the groups (39% vs 33%, p = .39). Analysis of 180 patients with preoperative and postoperative sleep study data revealed post-op Apnea Hypopnea Index (AHI) improved with both techniques (74% TT vs 79% IT, p = .7). There were no differences noted for persistent obstructive sleep apnea (OSA) among the two techniques for both study groups (p = .63).

CONCLUSION

Children with DD undergoing IT have reduced length of stay and reduced inpatient administration of post-operative opioids and steroids. IT has comparable efficacy to TT in treating symptoms of pediatric sleep apnea with a better safety profile. Overall, children undergoing IT return to the operating room less frequently than those undergoing TT. Longer follow-up studies will be needed to evaluate rate of tonsil regrowth, risk of revision surgery and persistence of OSA in these patients.

Impacts of Recurrent Tonsillitis on the Outcome of Powered Intracapsular Tonsillectomy in Children

Background and Objectives: To investigate the effects of recurrent tonsillitis on postoperative outcomes after powered intracapsular tonsillectomy and adenoidectomy (PITA) in children with obstructive sleep-disordered breathing (oSDB).Materials and Methods: Children who underwent PITA in Kyung Hee University Hospital at Gangdong from 2016 to 2018 were classified into two oSDB groups according to comorbid chronic/recurrent acute tonsillitis (CHT). To evaluate the efficacy of the PITA technique, quality of life (QoL) was measured using the obstructive sleep apnea questionnaire (OSA-18) for 3 months after surgery. To evaluate the disadvantages of the PITA technique, we followed complications such as throat pain, otalgia, nausea, vomiting, and postoperative bleeding for 1 week after surgery. Finally, we compared the pre- and postoperative QoL and analyzed the incidence of postoperative complications in the oSDB with CHT (SDBwCHT) and oSDB without CHT (SDBsCHT) groups.Results: Of the 802 enrolled patients, 135 were classified as SDBwCHT and 667 as SDBsCHT. Both groups exhibited marked improvements in QoL after PITA. The SDBwCHT group showed a change of OSA-18 score from 70.7±17.0 to 31.2±11.4. The SDBsCHT group showed a change of OSA-18 score from 70.0±17.1 to 31.0±9.9. The groups did not demonstrate statistical differences in complication rates and severity of symptoms during the first postoperative week.Conclusion: Although comorbid CHT delayed improvement in postoperative symptoms, PITA is a useful technique to treat children with oSDB, regardless of CHT.

Considerations in Surgical Management of Pediatric Obstructive Sleep Apnea: Tonsillectomy and Beyond

Obstructive sleep apnea (OSA) is an increasingly recognized disorder with a reported incidence of 5.7% in children. Tonsillectomy (with or without adenoidectomy) in pediatric OSA in otherwise healthy non-obese children has a success rate of approximately 75%. However, the cure rate reported for all children undergoing tonsillectomy varies from 51% to 83%. This article reviews the history of tonsillectomy, its indications, techniques, various methods, risks, and successes. The article also explores other surgical options in children with residual OSA post-tonsillectomy.

Predictive Pediatric Characteristics for Revision Tonsillectomy After Intracapsular Tonsillectomy

OBJECTIVES

There is little research on the rate and risk factors for revision tonsillectomy after primary intracapsular tonsillectomy. Our study aimed to determine the revision rate following intracapsular tonsillectomy, identify patient characteristics that may increase the probability of revision surgery, and report the tonsillar hemorrhage rate after revision.

STUDY DESIGN

Level III, retrospective case-control study.

SETTING

A tertiary care pediatric center (Alfred I. duPont Hospital for Children, Wilmington, Delaware).

METHODS

A case-control study of pediatric patients who underwent intracapsular tonsillectomy between January 1, 2004, and December 31, 2018, was performed. Patients aged 2 to 20 years were analyzed and compared with matched controls who underwent intracapsular tonsillectomy within 7 days of the same surgeon's case. In total, 169 revision procedures were included with 169 matched controls.

RESULTS

A 1.39% revision rate was observed among a total of 12,145 intracapsular tonsillectomies. Among the 169 patients who underwent a revision procedure, the mean time between cases was 3.5 years. Tonsillitis was the most common diagnosis prompting revision tonsillectomy. Four (2.4%) patients underwent operative control of a postoperative tonsillar hemorrhage after revision surgery. Younger patients (P < .001) and patients with a history of gastroesophageal reflux disease (P = .006) were more likely to undergo revision tonsillectomy.

CONCLUSION

Patients below age 4 years and patients with gastroesophageal reflux disease may be at increased risk of undergoing revision tonsillectomy after primary intracapsular tonsillectomy. These factors should be considered when selecting an intracapsular technique for primary tonsillectomy in pediatric patients.

Does perioperative ketorolac increase bleeding risk after intracapsular tonsillectomy?

IMPORTANCE

Conflicting evidence exists regarding the post-tonsillectomy bleed risk associated with perioperative ketorolac use in the pediatric population. Surgical technique for tonsillectomy can further confound this risk.

OBJECTIVE

The primary objective was to retrospectively quantify the post-tonsillectomy bleed rate after single-dose administration of ketorolac in pediatric patients following intracapsular tonsillectomy. The secondary objective was to determine if age, sex, body mass index, medical comorbidities, and indication for surgery increased post-tonsillectomy bleed risk.

DESIGN

Retrospective cohort study of 1920 children who underwent intracapsular tonsillectomies between January 2017 and December 2018.

SETTING

This study was completed at a tertiary-care pediatric referral center.

PARTICIPANTS

1920 children who underwent intracapsular tonsillectomies between January 2017 and December 2018 at a single tertiary-care children's hospital.

EXPOSURES

Patients were divided into two cohorts: 1458 patients (75.9%) received ketorolac (K+), and 462 (24.1%) did not (NK). Age, sex, body mass index, comorbidities, and indication for surgery also were evaluated for association with post-tonsillectomy bleed risk.

MAIN OUTCOME(S) AND MEASURE(S)

Primary study outcome for both cohorts was post-tonsillectomy hemorrhage requiring operative intervention.

RESULTS

1920 study participants were included with an average age of 6.5 years; 51.5% of participants were males; and, 63.9% were white. Overall, the postoperative bleeding rate was 1.5%. However, there was no significant difference when comparing bleeding rates for the ketorolac group and the non-keterolac group (1.4%-1.7%; P = .82) Age, chronic tonsillitis, higher body mass index Z-scores, attention-deficit/hyperactivity disorder, and behavioral diagnoses were statistically significant risk factors for post-tonsillectomy hemorrhage.

CONCLUSIONS AND RELEVANCE

Single-dose postoperative ketorolac does not appear to be associated with increased risk of post-tonsillectomy bleed in pediatric patients undergoing intracapsular tonsillectomy. Providers should not avoid using ketorolac in patients undergoing intracapsular tonsillectomy due to concerns over bleeding risk.

Coblation intracapsular tonsillectomy in children: A prospective study of 1257 consecutive cases with long-term follow-up

OBJECTIVES

Intracapsular tonsillectomy (ICT) is increasingly adopted by paediatric centres worldwide due to its association with reduced pain, fast recovery and low risks of post-operative complications. Questions still surround its role in patients with recurrent tonsillitis, as well as tonsillar regrowth requiring revision surgery.

DESIGN

Prospective consecutive case series from March 2013 to April 2020.

SETTING

Tertiary paediatric ENT referral centre.

PARTICIPANTS

Paediatric patients undergoing Coblation ICT, with or without adenoidectomy, for obstructive and/or infective indications.

MAIN OUTCOME MEASURES

Health-Related Quality of Life (HRQL), analgesia requirement, post-operative haemorrhage rates, time to return to normal diet and activity or school/nursery, and parental satisfaction. We report revision surgery rates and identify predictive factors for revision surgery.

RESULTS

A total of 1257 patients (median age 4.2 years) underwent Coblation ICT, with a median direct and implied follow-up of 101.5 and 1419 days, respectively. We noted significantly improved HRQL scores across all domains. Median analgesia requirement was six days, and no patients required a return to theatre for post-operative haemorrhage. The majority of patients were eating a normal diet within 24 hours and returned to normal activity/school within a week post-operatively. Revision surgery was required in 2.6% of cases, mainly due to recurrent obstructive symptoms from tonsillar regrowth. Being under two years old at initial surgery (OR 5.10), having severe OSA (OR 4.43) or severe comorbidities (OR 2.98) increased the risk of needing revision surgery.

CONCLUSIONS

Long-term data demonstrate the efficacy and safety of Coblation ICT in paediatric patients across a range of indications.

Effects of Osteopathic T9-T10 Vertebral Manipulation in Tonsillitis: A Randomized Clinical Trial

This study aimed to determine whether osteopathic manipulation of the T9-T10 vertebrae improves the evolution of tonsillitis. A randomized, stratified, controlled clinical trial with blinded patients, evaluator and data analyst was performed. The patients in the control group (CG) underwent a "sham" manipulation. A high-speed, low-amplitude technique was applied to the T9-T10 vertebrae in the osteopathic manipulative group (OMG) patients. The number of days needed to resolve the tonsillitis was significantly lower (p = 0.025) in the OMG (2.03 ± 0.95 days) than the CG (2.39 ± 0.82 days). Additionally, the number of episodes of tonsillitis after the treatment decreased significantly more in the OMG (0.8 ± 1.88 episodes/year in total) than the CG (2 ± 2.12) (p = 0.005). In the OMG, 60.8% had no recurrences of tonsillitis, compared to 22.5% of the CG, in the following year (χ2 (1) = 15.57, p < 0.001). No patients reported adverse effects. It has been concluded that during an episode of tonsillitis, the number of days to resolution was significantly lower after the application of an osteopathic manipulation of the T9-T10 vertebrae, compared to a sham manipulation. The number of subsequent year tonsillitis episodes was greatly reduced in both groups, significantly more in the OMG than in the CG patients.

Current Status and Future Trends: Pediatric Intracapsular Tonsillectomy in the United States

OBJECTIVES

1) To assess the current status of pediatric intracapsular tonsillectomy in the United States, and 2) To apply lessons from the scientific literature and adoption of surgical innovation to predict future trends in pediatric intracapsular tonsillectomy.

METHODS

This was a cross-sectional survey study and literature review. An anonymous survey was sent to all members of the American Society of Pediatric Otolaryngology (ASPO) to determine current practices in pediatric tonsillectomy. Statistical analysis was performed to compare differences in individuals who perform intracapsular tonsillectomy as opposed to extracapsular tonsillectomy. A literature analysis of the adoption of new technological advancements and innovative surgical techniques was then performed.

RESULTS

The survey was sent to 540 pediatric otolaryngologists with a response rate of 42%. Of all respondents, 20% currently perform intracapsular tonsillectomy. The primary reason cited for not performing the procedure was concern for tonsillar regrowth. Time in practice, practice setting, and fellowship status was not associated with an increased incidence of intracapsular tonsillectomy.

CONCLUSIONS

Only 20% of pediatric otolaryngologist respondents in the United States perform intracapsular tonsillectomy. Based on the documented advantages of intracapsular tonsillectomy over extracapsular tonsillectomy and an analysis of adoption of novel surgical techniques, we predict a paradigm shift in the specialty toward intracapsular tonsillectomy.

Intraoperative intravenous ibuprofen use is not associated with increased post-tonsillectomy bleeding

OBJECTIVES

Intravenous (IV) ibuprofen was approved by the FDA for use in pediatric patients in November 2015. The objective of this study was to compare bleeding rates in pediatric tonsillectomy patients who received intraoperative intravenous ibuprofen versus those who did not. Secondary objectives included analyzing factors that correlated with return to the Emergency Department (ED) for pain or dehydration.

METHODS

Charts were reviewed for all patients 0-18 years of age who underwent a tonsillectomy with or without adenoidectomy at a tertiary care children's hospital from 1/1/2017 through 5/21/2018. Demographic information and perioperative medications including the use of intraoperative intravenous ibuprofen were recorded. ED visits and operating room (OR) returns for bleeding were tracked for up to 30 days after surgery.

RESULTS

1085 charts were analyzed. Intraoperative IV ibuprofen was used in 132 cases (12.2%). Primary bleeds, defined as bleeding within 24 h of surgery, occurred in 1 (0.76%) of 132 patients who received IV ibuprofen, and 1 (0.10%) of 953 patients who did not receive IV ibuprofen. Secondary bleeds, defined as bleeds after 24 h from surgery occurred in 2 (1.52%) of 132 patients who received IV ibuprofen and 38 (3.99%) of 953 patients who did not receive IV ibuprofen. No statistical difference was found between the two groups in rates of overall (primary plus secondary) bleeding requiring return to ED (p = 0.759) or return to OR (p = 0.710).

CONCLUSION

The observed bleeding rate after pediatric tonsillectomy was not statistically different in patients who received intraoperative IV ibuprofen versus those who did not receive this medication.

Methodological Quality of Systematic Reviews and Meta-analyses Published in High-Impact Otolaryngology Journals

OBJECTIVE

To assess the methodological quality of intervention-focused systematic reviews (SRs) and meta-analyses (MAs) published in high-impact otolaryngology journals.

DATA SOURCES

Ovid Medline, Embase, and Cochrane Library.

REVIEW METHODS

A comprehensive search was performed for SR and MA citations from 2012 to 2017 in the 10 highest impact factor otolaryngology journals. Abstracts were screened to identify published manuscripts in which the authors indicated clearly that they were performing an SR or MA. Applying a modified typology of reviews, 4 reviewers characterized the review type as SR, MA, or another review type. A simplified version of the AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews 2) tool was used to assess the reporting and methodological quality of the SRs and MAs that were focused on interventions.

RESULTS

Search and abstract screening generated 499 manuscripts that identified themselves as performing an SR or MA. A substantial number (85/499, 17%) were review types other than SRs or MAs, including 34 (7%) that were literature reviews. In total, 236 SRs and MAs focused on interventions. Over 50% of these SRs and MAs had weaknesses in at least 3 of the 16 items in the AMSTAR 2, and over 40% had weaknesses in at least 2 of the 7 critical domains. Ninety-nine percent of SRs and MAs provided critically low confidence in the results of the reviews.

CONCLUSION

Intervention-focused SRs and MAs published in high-impact otolaryngology journals have important methodological limitations that diminish confidence in the results of these reviews.

Tonsillotomy versus Tonsillectomy for Chronic Recurrent Tonsillitis in Children

Objective

This study was conducted to compare two different surgical methods; partial tonsil resection using the bipolar technique, tonsillotomy (TT), and total tonsillectomy (TE) (blunt dissection) for recurrent tonsillitis in children. The frequency of recurrent throat infections was determined during postoperative follow-up.

Methods

A total of 393 patients were included in this study. TT was performed on 174 patients (100 males, 74 females) and TE on 219 patients (112 males, 107 females). Following surgery, an analysis was made of treatment outcomes of patients with upper respiratory tract infections. The patients were followed up for 12-48 months. Their parents were also contacted by telephone to determine the frequency of reinfection and their satisfaction with the surgery. Also, parents of the patients completed a questionnaire pertaining to postoperative satisfaction (scale of 1-10).

Results

In the TT group, 14 (8.1%) patients had recurrent tonsillitis postoperatively. In the TE group, 12 (5.4%) patients required antibiotherapy due to recurrent pharyngitis after the surgery. There was no significant difference between the two groups in terms of the one-year infection recurrence rate after surgery (p=0.281). Three patients (1.6%) in the TT group and 12 (5.4%) in the TE group complained of bleeding within the first 24 hours. The rate of bleeding was significantly lower in the TT group than the TE group (p=0.001). There were no fatalities in either group.

Conclusion

In both groups, the rate of reinfection accorded with the requirement for postoperative antibiotics. For recurrent tonsillitis, TT was as effective as TE. However, TT was superior in terms of the risk of bleeding.

Impact of allergic rhinitis on quality of life after powered intracapsular tonsillectomy and adenoidectomy

BACKGROUND

Allergic rhinitis (AR) has been reported to worsen quality of life (QoL) after adenotonsillectomy. Although powered intracapsular tonsillectomy and adenoidectomy (PITA) has been widely performed, it is not clear whether comorbid AR may worsen QoL in patients who undergo PITA.

PURPOSE

To evaluate QoL after PITA in relation to AR.

METHODS

Children undergoing PITA for sleep-disordered breathing were enrolled and divided into AR and non-AR groups. QoL was evaluated using serial applications of the Obstructive Sleep Apnea-18 (OSA-18) questionnaire and compared between the two groups.

RESULTS

Of 151 enrolled patients, 73 were categorized into the AR and 78 into non-AR groups. After surgery, patients exhibited marked improvement in OSA-18 scores in both groups, with similar results at each follow-up. The degree of improvement in OSA-18 scores was less in the AR group 3 months after surgery; however, this difference was not significant 6 months after surgery.

CONCLUSIONS

Although comorbid AR may initially appear to impede improvement in QoL after PITA, QoL was improved similarly 6 months after PITA, irrespective of AR status. In children with comorbid AR, PITA could be safely performed to treat sleep-disordered breathing without concerns regarding worsening of QoL.

Update review of pain control methods of tonsil surgery

Pain after tonsil surgery is troublesome because it causes discomfort. In addition, handling patients with postoperative pain is challenging to otolaryngologists. Many laboratory studies have assessed the use of analgesics and surgical techniques to discover methods for effective control of postoperative pain associated with tonsil surgery. In this review article, we summarize and provide a comprehensive overview of current methods for the control of pain after tonsil surgery based on findings of recent studies. Although powered intracapsular tonsillotomy is not popular yet, it seems to be an effective option among various surgical techniques. More discussion about powered intracapsular tonsillotomy should be done in the future. On the other hand, surgery with a harmonic scalpel, fibrin glue, or cryoanalgesia seems ineffective. When reviewing medical treatment methods, the use of nonsteroidal anti-inflammatory drugs, steroids, and/or gabapentin/pregabalin seems to be effective. However, the use of opioid (especially codeine) for children should be avoided because of possible respiratory insufficiency. Ketorolac is dangerous because of the risk of hemorrhage. We should continue to focus on the development of novel postoperative pain control techniques with no or low complications.

The development of an opioid sparing anesthesia protocol for pediatric ambulatory tonsillectomy and adenotonsillectomy surgery-A quality improvement project

Pain management following pediatric tonsillectomy and adenotonsillectomy surgery is challenging and traditionally involves perioperative opioids. However, the recent national opioid shortage compelled anesthesiologists at Bellevue Surgery Center to identify an alternative perioperative analgesic regimen that minimizes opioids yet provides effective pain relief. We assembled an interdisciplinary quality improvement team to trial a series of analgesic protocols using the Plan-Do-Study-Act cycle. Initially, we replaced intraoperative morphine and acetaminophen (M/A protocol) with intraoperative dexmedetomidine and preoperative ibuprofen (D/I protocol). However, when results were not favorable, we rapidly transitioned to intraoperative ketorolac and dexmedetomidine (D/K protocol). The following measures were evaluated using statistical process control chart methodology and interpreted using Shewhart's theory of variation: maximum pain score in the postanesthesia care unit, postoperative morphine rescue rate, postanesthesia care unit length of stay, total anesthesia time, postoperative nausea and vomiting rescue rate, and reoperation rate within 30 days of surgery. There were 333 patients in the M/A protocol, 211 patients in the D/I protocol, and 196 patients in the D/K protocol. With the D/I protocol, there were small increases in maximum pain score and postanesthesia care unit length of stay, but no difference in morphine rescue rate or total anesthesia time compared to the M/A protocol. With the D/K protocol, postoperative pain control and postanesthesia care unit length of stay were similar compared to the M/A protocol. Both the D/I and D/K protocols had reduced nausea and vomiting rescue rates. Reoperation rates were similar between groups. In summary, we identified an intraoperative anesthesia protocol for pediatric tonsillectomy and adenotonsillectomy surgery utilizing dexmedetomidine and ketorolac that provides effective analgesia without increasing recovery times or reoperation rates.
