Sociodemographic associations of geographic variation in paediatric tonsillectomy and adenoidectomy.

Geographic variation of paediatric tonsillectomy, with or without adenoidectomy, (A/T) has been described since the 1930s until today but no studies have investigated the factors associated with this variation. This study described the geographical distribution of paediatric A/T across the state of Victoria, Australia, and investigated area-level factors associated with this variation. We used linked administrative datasets capturing all paediatric A/T performed between 2010 and 2015 in Victoria. Surgery data were collapsed by patient residence to the level of Local Government Area. Regression models were used to investigate the association between likelihood of surgery and area-level factors. We found a 10.2-fold difference in A/T rates across the state, with areas of higher rates more in regional than metropolitan areas. Area-level factors associated with geographic variation of A/T were percentage of children aged 5-9 years (IRR 1.07, 95%CI 1.01-1.14, P = 0.03) and low English language proficiency (IRR 0.95, 95% CI 0.90-0.99, P = 0.03). In a sub-population analysis of surgeries in the public sector, these factors were low maternal educational attainment (IRR 1.09, 95% CI 1.02-1.16, P < 0.001) and surgical waiting time (IRR 0.99635 95% CI 0.99273-0.99997, P = 0.048). Identifying areas of focus for improvement and factors associated with geographic variation will assist in improving equitable provision of paediatric A/T and decrease variability within regions.

Tonsillitis, tonsillectomy, and deep neck space infections in England: the case for a new guideline for surgical and non-surgical management.

INTRODUCTION: Tonsillectomy is a common surgical procedure performed chiefly for recurrent tonsillitis. The Scottish Intercollegiate Guidance Network (SIGN) introduced guidelines in 1998 to improve patient selection for tonsillectomy and reduce the potential harm to patients from surgical complications such as haemorrhage. Since the introduction of the guidance, the number of admissions for tonsillitis and its complications has increased. National Hospital Episode Statistics over a 20-year period were analysed to assess the trends in tonsillectomy, post-tonsillectomy haemorrhage, tonsillitis and its complications with reference to the guidance, procedures of limited clinical value and the associated costs and benefits. MATERIALS AND METHODS: A literature search was conducted via PubMed and the Cochrane Library to identify relevant research. Hospital Episode Statistics data were interrogated and relevant data compared over time to assess trends related to the implementation of national guidance. RESULTS: Over the period analysed, the incidence of deep neck space infections has increased almost five-fold, mediastinitis ten-fold and peritonsillar abscess by 1.7-fold compared with prior to SIGN guidance. Following procedures of limited clinical value implementation, the incidence of deep neck space infections has increased 2.4-fold, mediastinitis 4.1-fold and peritonsillar abscess 1.4-fold compared with immediately prior to clinical commissioning group rationing. The rate of tonsillectomy and associated haemorrhage (1-2%) has remained relatively constant at 46,299 (1999) compared with 49,447 (2009) and 49,141 (2016), despite an increase in the population of England by seven million over the 20-year period. DISCUSSION: The rise in admissions for tonsillitis and its complications appears to correspond closely to the date of SIGN guidance and clinical commissioning group rationing of tonsillectomy and is on the background of a rise in the population of the UK. The move towards daycase tonsillectomy has reduced bed occupancy after surgery but this has been counteracted by an increase in admissions for tonsillitis and deep neck space infections, sometimes requiring lengthy intensive care stays and a protracted course of rehabilitation. The total cost of treating the complications of tonsillitis in England in 2017 is estimated to be around £73 million. The cost of tonsillectomy and treating post-tonsillectomy haemorrhage is £56 million by comparison. The total cost per annum for tonsillectomy prior to the introduction of SIGN guidance was estimated at £71 million with tonsillitis and its complications accounting for a further £8 million.

Factors Associated With Postadenotonsillectomy Unexpected Admissions in Children.

BACKGROUND: Postadenotonsillectomy unexpected admission remains an important challenge. Unexpected admissions can be quite frightening, increase health care burden, and cause unnecessary suffering in children and families. Identifying factors associated with postadenotonsillectomy unexpected admissions using a pragmatic approach could lead to a shift in the assessment and management of children presenting for adenotonsillectomy. METHODS: Institutional review board (IRB) approval, consent, and assent were obtained for this single-center, prospective, observational study done in children aged 0-17 years undergoing tonsillectomy. Data were collected from direct observation, electronic medical record, and phone calls using Research Electronic Data Capture (REDCap) database. Incidence, causes, and factors associated with 3-week and 3-day postadenotonsillectomy unexpected admissions were analyzed. RESULTS: The study included 2375 children. Clinical intraoperative adverse events were reported in 6.2%. Three-week and 3-day unexpected admissions occurred in 7.9% and 5.9%, respectively, with bleeding being the commonest reason for both. On multivariable analysis, for 3-week unexpected admissions, the odds ratio was 2.3 (95% confidence interval, 1.44-3.76) with using preoperative medications, 1.4 (1.02-1.97) with home medications for comorbidities, 0.56 (0.34-0.90) with using intraoperative acetaminophen, and 0.60 (0.36-0.94) with otolaryngologic preoperative comorbidity versus otherwise. For 3-day unexpected admissions, the odds ratio was 1.10 (1.05-1.16) with 1 U increase in total comorbidities, 1.70 (1.03-2.81) with the presence of recent upper respiratory infection, and 1.83 (1.16-2.90) with intravenous versus inhalational anesthesia induction. CONCLUSIONS: Overall, our study shows the factors that contribute to unexpected admissions postadenotonsillectomy. Identification of both modifiable and nonmodifiable factors associated with unexpected admissions after adenotonsillectomy will enable appropriate risk mitigation.

What's New with Tubes, Tonsils, and Adenoids?

Evidence-based recommendations are constantly being updated for various pediatric surgical procedures, including the role for tympanostomy tubes, as well as indications for adenoidectomy and tonsillectomy. With a growing body of research available on some of the most prevalent pediatric conditions, an update on the current concepts surrounding management is warranted.

Hospital admissions for acute throat and deep neck infections versus tonsillectomy rates in Germany.

PURPOSE: To evaluate trends in hospital admissions in Germany for acute infections of the upper airway and deep neck in the context of the number of tonsil-related surgical procedures between 2005 and 2017. METHODS: A retrospective longitudinal population-based cohort study was performed including all unplanned admissions for acute pharyngitis/tonsillitis, abscess formation of the peritonsillar or retropharyngeal/parapharyngeal space. Elective procedures included tonsillectomy (with or without adenoidectomy), secondary tonsillectomy, and tonsillotomy. Emergency operations encompassed abscess-tonsillectomy and transoral drainage procedures of the peritonsillar/parapharyngeal/retropharyngeal space. RESULTS: 553.600 admissions were registered in total with a significant, stepwise increase between 2005 and 2017, including retropharyngeal/parapharyngeal abscess (47.0%), acute tonsillitis (30.8%), acute pharyngitis (26.5%) and peritonsillar abscess (7.9%). There were 1.323.984 elective operations with a significant decrease during the study period. A total of 188.316 emergency operations were done, a significant decrease in the number of abscess-tonsillectomies was compensated by the increased number of transoral peritonsillar abscess drainages. The number of transoral parapharyngeal and retropharygeal abscess drainage procedures did not change significantly (p = 0.846; p = 0.846). Negative correlation was significant between admissions for chronic tonsillitis and emergency admissions (Pearson correlation coefficient = - 0.879, p < 0.001) and also between elective and emergency operations (r = - 0.667; p = 0.013). CONCLUSIONS: Concerning infections of the upper airway and deep neck spaces, German Hospitals have to prepare strategies for the increasing challenge by unplanned admissions and emergency operations. Further research is required to clarify whether this phenomenon is caused by the significant decrease in the number of elective operations.

The effect of adenotonsillectomy on ventilatory control in children with obstructive sleep apnea.

STUDY OBJECTIVES: The contribution of ventilatory control to the pathogenesis of obstructive sleep apnea (OSA) in children and the effect of adenotonsillectomy are unknown. We aimed to examine the difference in ventilatory control between children with OSA and those without OSA. We also examined the effect of adenotonsillectomy on parameters of ventilatory control. METHODS: Healthy children with OSA and matched controls were recruited. Polysomnography was performed before adenotonsillectomy in the OSA group and 6 months postoperatively. Controls underwent the same assessment at the two time points. Loop gain (LG), controller gain (CG), and plant gain (PG), which reflect the stability of ventilatory control, chemoreceptor sensitivity and the pulmonary control of blood gas in response to a change in ventilation, respectively, were estimated from polysomnographic tracings which included spontaneous sighs and tracings with tidal breathing. A linear mixed model was used to examine the changes of the ventilatory control parameters from baseline to 6 months. RESULTS: Ninety-nine children aged 7-13 were recruited to the study. Fifty-three with OSA and 46 controls. At baseline, compared with controls, children with OSA had higher PG and lower CG. LG did not differ between groups. Six months following adenotonsillectomy, there was a significant decrease in PG in the OSA group, while no change observed in the control group. CONCLUSIONS: The study demonstrates that the pulmonary control of blood gas homeostasis is disturbed in children with OSA and it normalizes following adenotonsillectomy.

Use of Oximetry to Determine Need for Adenotonsillectomy for Sleep-Disordered Breathing.

: media-1vid110.1542/5802711151001PEDS-VA_2017-3382Video Abstract OBJECTIVES: We evaluated the efficacy of adenotonsillectomy (T/A) in children with sleep-disordered breathing (SDB) in a controlled study using oximetry. We hypothesized that children with SDB and abnormal nocturnal oximetry in a community setting will have improved hypoxemia indices after T/A. METHODS: Children with snoring and tonsillar hypertrophy (4-10 years old) who were candidates for T/A were randomly assigned to 2 oximetry sequences (baseline and 3-month follow-up): (1) oximetry immediately before T/A and at the 3-month follow-up, which occurred postoperatively (T/A group); or (2) oximetry at the initial visit and at the end of the usual 3-month waiting period for surgery (control group). Outcomes were (1) proportion of subjects with McGill oximetry score (MOS) >1 at baseline acquiring MOS of 1 at follow-up and (2) proportion of subjects achieving oxygen desaturation (≥3%) of hemoglobin index (ODI3) <2 episodes per hour at follow-up if they had ODI3 ≥3.5 episodes per hour at baseline. RESULTS: One hundred and forty children had quality oximetry tracings. Twelve of 17 (70.6%) children with MOS >1 in the T/A group and 10 of 21 (47.6%) children with MOS >1 in the control group had MOS of 1 at follow-up (P = .14). More subjects in the T/A than in the control group achieved ODI3 <2 episodes per hour at follow-up (14 of 32 [43.8%] vs 2 of 38 [5.3%]; P < .001). Three children with elevated ODI3 were treated to prevent persistently abnormal ODI3 in 1 child at follow-up. CONCLUSIONS: An ODI3 ≥3.5 episodes per hour in nocturnal oximetry is related to increased resolution rate of nocturnal hypoxemia after T/A for SDB compared with no intervention.

Effect of adenotonsillectomy for childhood obstructive sleep apnea on nocturnal heart rate patterns.

Study Objectives: To assess the effect of adenotonsillectomy for relieving obstructive sleep apnea syndrome (OSAS) symptoms in children on cardiac autonomic modulation. Methods: In 354 children enrolled in the Childhood Adenotonsillectomy Trial, randomized to undergo either early adenotonsillectomy (eAT; N = 181) or a strategy of watchful waiting with supportive care (WWSC; N = 173), nocturnal heart rate control was analyzed during quiet, event-free sleep at baseline and at 7 months using overnight polysomnography (PSG). The relative frequency of patterns indicating monotonous changes in heart rate was quantified. Results: Children who underwent eAT demonstrated a significantly greater reduction in heart rate patterns postsurgery than the WWSC group. On assessing those heart rate patterns regarding normalization of clinical PSG, heart patterns were reduced to a similar level in both groups. In children whose AHI normalized spontaneously, heart rate patterns were already significantly less frequent at baseline, suggesting that upper airway obstruction was milder in this group at the outset. Conclusions: Adenotonsillectomy reduces monotonous heart rate patterns throughout quiet event-free sleep, reflecting a reduction in cardiac autonomic modulation. Heart rate pattern analysis may help quantifying the effect of OSAS on autonomic nervous system activity in children. Clinical Trial Registration: The study was registered at Clinicaltrials.gov (#NCT00560859).

Factors associated with changing indications for adenotonsillectomy: A population-based longitudinal study.

OBJECTIVE: Adenotonsillectomy (AT) is one of the most common surgical procedures performed in children and adults. We aim to assess the factors associated with changes in the incidence of and indications for AT using population-level data. STUDY DESIGN: This retrospective cohort study investigated patients who underwent AT between 1997 and 2010 by using data from the Taiwan National Health Insurance Research Database. We examined surgical rates and indications by the calendar year as well as age, sex, hospital level, and insured residence areas for the correlating factors. RESULTS: The average annual incidence rate of AT was 14.7 per 100,000 individuals during 1997-2010. Pediatric (<18 years) patients represented 48.2% of the total AT population. More than 99% of the patients underwent the AT procedures as an inpatient intervention. Longitudinal data demonstrated an increasing trend in the pediatric AT rates from 1997 (4.3/100,000) to 2010 (5.7/100,000) (p = 0.029). In the adult subgroup, a decreasing prevalence of infectious indications (p = 0.014) coincided with an increasing neoplastic indications (p = 0.001). In the pediatric subgroup, the prevalence of obstructive indications increased (p = 0.002). The logistic regression analyses indicated that the significant factors associated with the changing surgical indications for AT were the age in the adult subgroup and hospital level in the pediatric subgroup. CONCLUSIONS: This study revealed a low AT rate in Taiwan than that in other countries. Pediatric AT incidence increased during 1997-2010. Although a rising prevalence of obstructive and neoplastic indications was noted, infection remained the most common indications for AT. Age in the adult subgroup and hospital level in the pediatric subgroup were factors associated with the changing indications for AT.

Trend in otolaryngological surgeries in an era of super-aging: Descriptive statistics using a Japanese inpatient database.

OBJECTIVE: To reveal the age distribution and capture the longitudinal trend in otolaryngological surgeries performed in Japan, where society is rapidly aging. METHODS: Using the Diagnosis Procedure Combination database, we extracted data on patients who were hospitalized and underwent any type of otolaryngological surgery in departments of otolaryngology or head and neck surgery from fiscal year 2007 to fiscal year 2013. Type of surgery, patient's age, and fiscal year were compared. We categorized >200 types of surgeries into eight specialties: ear surgery, functional endoscopic sinus surgery (FESS), other types of paranasal surgery (except for malignancy), head and neck cancer surgery, benign tumor surgery, upper airway surgery (including pharynx and larynx), removal of foreign body, and other. RESULTS: In total, 558,732 patients were included. The proportions of patients in each age category formed two peaks in middle age and in children aged ≤9years. The proportion of all surgeries made up by FESS, other paranasal surgery, benign tumor surgery, and head and neck cancer surgery gradually increased with age, forming a peak in patients in their 60s. The proportion of ear surgery was highest in patients aged ≤9years (34.0% of all surgeries, mostly myringotomy and transtympanic ventilation tube insertion) and formed a gradual peak in patients in their 60s (mostly tympanoplasty). The proportion of upper airway surgery (tonsillectomy and adenoidectomy) was highest in patients aged ≤9years (25.3% of all surgeries). The proportion of foreign body removal was highest in patients aged ≤9years (52.2% of all surgeries) and increased slightly with age. In 2013, compared with 2007, those aged 65-74 years and ≥75years made up a larger percentage of patients undergoing each specific surgery, including tympanoplasty, stapedectomy/stapedotomy, FESS, head and neck cancer surgery, pharyngolaryngectomy, total/subtotal glossectomy, thyroid lobectomy, parotidectomy (for a benign tumor), submandibular gland resection, tonsillectomy, and vocal fold polypectomy. CONCLUSION: The age distribution of otolaryngological surgeries varied by specialty. We found an increased proportion of patients aged 65-74 and ≥75years in most specific surgeries.

Are postoperative behavioural changes after adenotonsillectomy in children influenced by the type of anaesthesia?: A randomised clinical study.

BACKGROUND: Negative postoperative behavioural changes (NPOBCs) are very frequent in children after surgery and general anaesthesia. If they persist, emotional and cognitive development may be affected significantly. OBJECTIVE: To assess whether the choice of different anaesthetic techniques for adenotonsillectomy may impact upon the incidence of NPOBC in repeated measurements. DESIGN: A randomised, controlled, parallel-group trial. SETTING: University Hospital Split, Croatia. PATIENTS: Sixty-four children (aged 6 to 12 years, ASA 1 to 2) undergoing adenotonsillectomy assigned into one of two groups: sevoflurane (S) (n = 32) or total intravenous anaesthesia (TIVA) (n = 32). INTERVENTIONS: Permuted-block randomisation with random block sizes of 4, 6 and 8, administering anaesthesia, and evaluation of NPOBC with the Post Hospitalization Behavior Questionnaire (PHBQ: 27 items describing six subscales). The PHBQ was filled out by parents at postoperative days (POD) 1, 3, 7 and 14, and 6 months after surgery. MAIN OUTCOME MEASURES: Differences in numbers of NPOBCs between two anaesthesia techniques, and NPOBC analysis by subscales. RESULTS: The prevalence of at least one NPOBC after surgery ranged from a maximum of 80% [95% confidence interval (CI) 71 to 90%] on POD 1 to a minimum of 43% (95% CI 31 to 56%) 6 months after surgery. Absolute risk reduction for at least one NPOBC in the TIVA group compared with the S group increased from 0.24 on POD 1 to 0.55 6 months after surgery. The number of NPOBCs was also lower in the TIVA group [median 5, interquartile range (IQR) 2 to 10] than in the S group (median 22, IQR 10 to 32) (P < 0.001). The overall number of NPOBCs within PHBQ subscales was significantly lower in the TIVA group than in the S group. The largest difference in the number of NPOBCs between groups was observed for the separation anxiety subscale (mean 5, 95% CI 1 to 9; P < 0.001) followed by the general anxiety subscale (mean 4, 95% CI 3 to 5; P < 0.001) and apathy/withdrawal subscale (mean 3, 95% CI 1 to 5; P < 0.001). CONCLUSION: The prevalence of NPOBC after elective adenotonsillectomy in 6 to 12-year-old children was very high (80%). The choice of anaesthetic technique for adenotonsillectomy in children influenced the incidence and type of NPOBC. Sevoflurane/nitrous oxide anaesthesia was associated with more frequent and prolonged NPOBCs than TIVA, especially in the separation anxiety, general anxiety and withdrawal/apathy subscales.

[The evolution of adenoidectomy].

The critical analysis of publications concerning methods designed for the surgical treatment of adenoids is presented. Various surgical techniques are considered with special reference to their indications for use, invasiveness, effectiveness, and safety. Recent developments in this field give evidence that evolution of adenoidectomy brought about highly efficacious (up to 99%) mini-invasive and safe surgical procedures producing the minimal risk of relapses and postoperative complications. All these advancements became possible due to the introduction of endoscopic intraoperative control, general anesthesia, and the use of modern surgical instruments. Modern approaches make unnecessary radical removal of the lymphoid tissue.

Trends in the indications for pediatric tonsillectomy or adenotonsillectomy.

OBJECTIVE: To report trends in the indications for pediatric tonsillectomy or adenotonsillectomy. METHODS: To identify current indications, (1) a retrospective chart review analyzed all indications for procedures performed by a pediatric otolaryngologist on patients aged 0-3, 4-10, or 11-18 years, and (2) a cross-sectional survey to members of the American Society of Pediatric Otolaryngology asked for approximate percentages of children in the same age groups receiving procedures for obstruction, infection, or another indication. To assess changing indications over time, (3) a literature review was performed. RESULTS: (1) Chart review: 302 patients aged 5 months to 18 years (average: 6.34; median: 6) were analyzed. For the 0-3-year age group, obstruction was an indication in 100.0% of cases, and infection in 2.6%. For the 4-10-year age group: 91.9% and 13.4%, respectively. For the 11-18-year age group: 84.6% and 33.3%. (2) SURVEY: 120 surveys were returned (40% response rate), and 63 surveys were appropriate for analysis (21% completion rate). For the 0-3-year age group, obstruction was the primary indication in 91.8% of procedures and infection in 7.5%. For the 4-10-year age group: 73.2% and 25.3%, respectively. For the 11-18-year age group: 43.0% and 54.2%. (3) LITERATURE REVIEW: 11 articles consistently illustrated a rise in obstruction and a decline in infection as an indication since 1978. CONCLUSIONS: Obstruction has become a more prominent indication than infection for pediatric tonsillectomy or adenotonsillectomy in children, especially younger children. Infection becomes a more prominent indication as age increases. Data may not be absolutely reflective of all pediatric otolaryngologists or other otolaryngologists that treat children. Comparing studies is difficult owing to the variety of surgical procedures focused upon and terms used to define indications.

Changes and consistencies in the epidemiology of pediatric adenotonsillar surgery, 1996-2006.

OBJECTIVE: Determine changes in rates for pediatric adenotonsillar procedures over time with attention to infectious indications. STUDY DESIGN: Historical cohort study. SETTING: Academic medical center. SUBJECTS AND METHODS: The National Survey of Ambulatory Surgery and the National Hospital Discharge Survey 1996 and 2006 releases were examined, extracting all cases of pediatric tonsillectomy, adenotonsillectomy, and adenoidectomy. The aggregate numbers and rates of adenotonsillar procedures performed overall and specifically for chronic infectious etiologies were determined. These procedure rates were then compared to determine differences in performance rates between 1996 and 2006. RESULTS: In 1996, an estimated 441,870 ± 23,315 children underwent some form of adenotonsillar surgery in the ambulatory and inpatient settings (60,034 ± 6994 tonsillectomies, 255,217 ± 18,960 adenotonsillectomies, and 126,619 ± 11,627 adenoidectomies), while in 2006, the total rose to 695,029 ± 36,979 children (58,111 ± 9645 tonsillectomies, 506,778 ± 32,054 adenotonsillectomies, and 129,540 ± 15,714 adenoidectomies). However, when examined according to infectious indications, a notable decline in the population rate of tonsillectomy from 0.62 per 1000 children in 1996 to 0.53 per 1000 in 2006 was found (P = 0.252). Moreover, the larger decline in the rate of adenotonsillectomy for infectious indications from 2.20 per 1000 to 1.46 per 1000 was significant (P = 0.003). There was no significant change adenoidectomy rates for chronic infectious etiologies (0.25 versus 0.21 per 1000, P = 0.326). CONCLUSION: Although there was an overall increase in the rate of performance of adenotonsillar surgery, population adjusted performance rates of these procedures specifically for infectious indications declined from 1996 to 2006.

Variability of adenoidectomy/tonsillectomy rates among children of the Veneto Region, Italy.

BACKGROUND: Despite national guidelines in 2003 aimed at limiting the recourse to tonsillectomy and/or adenoidectomy (A/T), the latter are among the most frequent pediatric surgeries performed in Italy. Aim of the study is to investigate variability of A/T rates among children of the Veneto Region, Italy. METHODS: All discharges of Veneto residents with Diagnosis-Related Groups 57-60 and ICD9-CM intervention codes 28.2 (tonsillectomy), 28.3 (adenotonsillectomy), 28.6 (adenoidectomy) were selected in the period 2000-2006 for a descriptive analysis. A multilevel Poisson regression model was applied to estimate Incidence Rate Ratios (IRR) with 95% Confidence Intervals (CI) for A/T surgery among children aged 2-9 years in 2004-2006, while taking into account clustering of interventions within the 21 Local Health Units. RESULTS: Through 2000-2006, the overall number of A/T surgeries decreased (-8%); there was a decline of adenoidectomies (-20%) and tonsillectomies (-8%), whereas adenotonsillectomies raised (+18%). Analyses on children aged 2-9 resulted in an overall rate of 14.4 surgeries per 1000 person-years (16.1 among males and 12.5 among females), with a wide heterogeneity across Local Health Units (range 8.1-27.6). At random intercept Poisson regression, while adjusting for sex and age, intervention rates were markedly lower among foreign than among Italian children (IRR = 0.57, CI 0.53-0.61). A/T rates in the 10-40 age group (mainly tonsillectomies) computed for each Local Health Unit and introduced in the regression model accounted for 40% of the variance at Local Health Unit level of pediatric rates (mainly adenoidectomies and adenotonsillectomies). CONCLUSION: A/T rates in the Veneto Region, especially adenoidectomies among children aged 2-9 years, remain high notwithstanding a decrease through 2000-2006. A wide heterogeneity according to nationality and Local Health Units is evident. The propensity to A/T surgery of each Local Health Unit is similar in different age groups and for different surgical indications.

Trends in otitis media surgery: a decrease in adenoidectomy.

OBJECTIVE: Large variability in adenoidectomies and tympanostomy tube insertions between Norway and Finland has been suggested, but not yet confirmed. Objective is to compare trends in paediatric adenoidectomies and tympanostomy tube insertions for Norway and Finland from 1999 to 2005. METHODS: National Finnish and Norwegian databases (STAKES and NPR) provided information on children between 0 and 7 years operated in the years 1999-2005. Surgical rates were viewed in the light of child density, age and gender, and compared bi-nationally. RESULTS: Adenoidectomies were more common in Finland throughout the study period. Adenoidectomies in both countries decreased markedly from 1999 to 2005. The Finnish adenoidectomy rates were reduced from 212 to 133 per 10,000 children, equivalent Norwegian figures were 84 and 44 per 10,000 children. Tympanostomy tube insertions increased from 97 to 147 per 10,000 children in Finland in the same study period. In Norway the rates were more stable, 119 and 123 per 10,000 in 1999 and 2005, respectively. Peak-age for otitis media surgery was the second year of life in Finland, sixth in Norway. Boys were more frequently operated on in both countries. CONCLUSION: Our study confirmed differences in the approach to otitis media surgery and revealed a decreasing trend in adenoidectomies in both countries. Similar data from other countries is needed to confirm the latter.

Tonsillectomy and adenoidectomy techniques: past, present and future.

Although the number of procedures has significantly decreased over the past century, tonsillectomy and adenoidectomy are commonly performed surgeries in the pediatric group, with obstructive sleep apnea being the most common indication. Despite the availability of newer technologies, tonsillectomy is still associated with a relatively high risk of postoperative morbidity. Pain and postoperative bleeding can have a significant impact on the child's health and quality of life. This article reviews the currently available techniques for tonsillectomy and adenoidectomy, with their characteristics and potential benefits. No gold standard exists at this point, and further prospective clinical trials are needed in this perspective.

Past and present instrument use in pediatric adenotonsillectomy.

OBJECTIVE: Examine changing trends/instrument usage for pediatric adenotonsillectomy. STUDY DESIGN AND SETTING: Survey of 300 members of the American Society of Pediatric Otolaryngology assessing instruments used in adenotonsillectomy currently and over the past 15 years. RESULTS: A total of 120 surveys were returned. The most common total tonsillectomy instruments for obstruction/infection were: monopolar electrocautery (ME) (53.1%/54.5%) and coblation (CT) (16.0%/16.1%). The most common subtotal tonsillectomy instrument for obstruction/infection was microdebrider (51.4%/30.8%). Over the past 15 years, ME predominated, cold utilization declined, and CT rose. The most common adenoidectomy instruments were ME (25.0%/25.0%), curette with touch-up ME (22.4%/22.4%), and microdebrider with touch-up ME (19.0%/14.7%). Over the past 15 years, curette with touch-up ME predominated early, curette utilization alone declined, and ME, microdebrider, and CT have risen. CONCLUSION: Pediatric otolaryngologist technique/instrument use for adenotonsillectomy has changed over the past 15 years. This study may be limited by the low survey response rate.

Coblation adenotonsillectomy: an improvement over electrocautery technique?

OBJECTIVES: To compare postoperative complication rates of coblation and electrocautery adenotonsillectomies. STUDY DESIGN: Retrospective chart review. RESULTS: From January 2000 to June 2004, 1997 pediatric patients underwent adenotonsillectomy. 745 coblation, and 1252 electrocautery tonsillectomies were performed. Primary bleed, secondary bleed, and dehydration were seen in 3, 35, and 23 coblation, and 9, 41, and 64 electrocautery tonsillectomies, respectively. Data analysis revealed no significant difference in primary and secondary hemorrhage rate, but a higher dehydration rate in the electrocautery group (P=0.0423). A total of 602 coblation, 763 curette/cautery, and 632 electrocautery adenoidectomies were performed. Neck pain was seen in 0, 17, and 3 patients, respectively. Data analysis showed a higher incidence of neck pain with the curette/cautery technique compared with coblator and cautery techniques (P=0.0006 and P=0.0119, respectively). CONCLUSIONS: Coblation tonsillectomy had similar rates of primary and secondary hemorrhage when compared with electrocautery tonsillectomy but a lower incidence of postoperative dehydration. Coblation adenoidectomy caused less postoperative neck pain than curette/cautery adenoidectomy without significant advantage over cautery adenoidectomy. EBM RATING: B-3b.
