Sedgwick MJ, Saunders C, Bateman N. Intracapsular Tonsillectomy Using Plasma Ablation Versus Total Tonsillectomy: A Systematic Literature Review and Meta-Analysis. OTO Open 2023; 7:e22. [PMID: 36998549 PMCID: PMC10046729 DOI: 10.1002/oto2.22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 11/28/2022] [Accepted: 12/02/2022] [Indexed: 02/19/2023] Open
Abstract
Objective To determine whether intracapsular tonsillectomy, using plasma ablation, results in differences in postoperative patient outcomes to total tonsillectomy. Data Sources A systematic review of two databases (Embase and PubMed) was conducted in March 2022 to identify published English-language randomized controlled trials and observational studies which provided a comparison between intracapsular tonsillectomy, using plasma ablation, and total tonsillectomy. Review Methods Qualitative synthesis and meta-analysis were used to compare outcomes between techniques. Results Seventeen studies were identified for inclusion. Across these, 1996 and 4565 patients underwent intracapsular and total tonsillectomy, respectively. Studies included 8 randomized controlled trials, 1 prospective cohort study, and 8 retrospective cohort studies. Time to pain free, time on analgesia, time to normal diet, and time to normal activity were significantly shorter with intracapsular tonsillectomy by on average 4.2 (95% confidence interval [CI] 1.5-5.9; p < .0001), 4.1 (95% CI 2.7-5.4; p < .0001), 3.5 (95% CI 1.7-5.4; p = .0002) and 2.8 (95% CI 1.6-4; p < .0001) days, respectively. Risk of posttonsillectomy hemorrhage was significantly lower following intracapsular tonsillectomy (relative risk [RR] 0.36; 95% CI 0.16-0.81; p = .0131); risk of posttonsillectomy hemorrhage requiring surgical management was lower but failed to reach significance (RR 0.52; 95% CI 0.19-1.39; p = .19). Conclusion Intracapsular tonsillectomy using plasma ablation has similar efficacy in managing indications for tonsil surgery to total tonsillectomy while significantly reducing the postoperative morbidity and likelihood of posttonsillectomy hemorrhage experienced by patients, allowing them to return to their normal life faster.

Abstract
To compare radiofrequency and electrocauterization in reducing the degree of postoperative pain in pediatric patients undergoing tonsillectomy. A double-blind, parallel-group, randomized controlled trial. Pediatric patients with indications for tonsillectomy were randomized to receive either tonsillectomy with radiofrequency or electrocautery. Also recorded were intraoperative blood loss, duration of the surgery, length of hospital stays, and complications from the surgery. Forty pediatric patients participated in the study; 20 were randomized to each group. The participants' ages ranged from 3 to 14 years old, and 65% were male. The overall postoperative pain scale score during the early postoperative period was lower in the radiofrequency group compared to the electrocautery group (mean difference - 1.37 (95%CI - 1.72, - 0.12); p < 0.001). Also, the mean pain scale scores at 6 h, 1, and 2 days were significantly lower in the radiofrequency group. Intraoperative blood loss and length of hospital stay in the radiofrequency group were also significantly lower than in the electrocautery group, whereas the duration of the surgery and complication rate were not different between the two groups. Pediatric tonsillectomy using radiofrequency ablation could reduce the severity of early postoperative pain, intraoperative blood loss, and length of hospital stay compared to tonsillectomy with electrocautery. Therefore, tonsillectomy with radiofrequency may be considered a safe and effective operative option. Trial registration Thai Clinical Trials Registry (TCTR-20210303007), 03-March-2021.

Abstract
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. TRIAL REGISTRATION NUMBER NCT03654742.

Abstract
OBJECTIVES Tonsillectomy is an extremely common ENT surgical procedure. There is a growing interest in the role of intracapsular dissection tonsillectomy (ICDT) due to reported reduced perioperative complications. We aim to compare the outcomes associated with ICDT versus traditional extracapsular dissection tonsillectomy (ECDT) in the adult population. METHODS Systematic review of all randomized controlled trials (RCTs) comparing ICDT and ECDT for all indications in the adult population. Electronic searches performed through CENTRAL, PubMed, Ovid EMBASE, Web of Science, ClinicalTrials.gov, and WHO ICTRP. Review Manager 5.3 (RevMan 2014) was used to carry out the meta-analysis. RESULTS Nine RCTs were included with a total of 11 reports with mean age of 23.9 years including 181 patients who received ICDT compared to 176 patients receiving ECDT. We found statistically significant reduced postoperative pain and analgesia requirement as well as a reduced rate of secondary postoperative bleeding in patients undergoing ICDT versus ECDT. There appears to be no significant difference in controlling recurrent tonsillitis between the ICDT and ECDT groups. CONCLUSION Across the recorded outcomes we noted no clear benefit to performing ECDT over ICDT and evidence suggests high patient satisfaction with ICDT. Laryngoscope, 130:2325-2335, 2020.

Abstract
OBJECTIVE Tonsillotomy has emerged as an alternative for tonsillectomy in treating patients with tonsil-related afflictions. Tonsillotomy provides favourable outcomes in children, but treatment of choice in adults remains unclear. This systematic review sought to evaluate the current literature on the efficacy and adverse events of tonsillotomy compared to tonsillectomy in adults. METHODS A Medline and Cochrane search was conducted for randomized clinical trials (RCTs) and cohort studies comparing tonsillotomy to tonsillectomy in adults. Risk of bias was assessed. Outcome measures were efficacy of the procedure in resolving the initial tonsil-related symptoms (tonsillitis, obstructive sleep apnoea, tonsil stones, halitosis, dysphagia), procedure-related complications, recovery time, post-operative use of analgesics, patient satisfaction, and operating time. RESULTS In total nine papers were included. These trials had a high risk of bias and the inter-comparability of results was poor. The reported studies found generally a similar efficacy for both interventions. With regard to pain, the use of analgesics, patient satisfaction and operation time, the results were generally in favour of tonsillotomy. Post-operative haemorrhages were more frequent after tonsillectomy. CONCLUSION Current evidence suggests an equal efficacy of tonsillotomy and tonsillectomy in adults and a preference for tonsillotomy in terms of pain, analgesics use, patient-satisfaction, operation time and post-operative complications.

Abstract
Post tonsillectomy bleeding and pain are two main problems following traditional tonsillectomy. Coblation therapy (controlled ablation) was first used in tonsillectomy in 2001. A great amount of literature debated around its use with controversial opinions regarding its benefits, efficacy, and cost. This is a prospective double-blind randomized controlled study that compares between coblation tonsillectomy and conventional tonsillectomy as regard operative time, operative blood loss, time needed to return back to the normal activity and diet, and incidence of postoperative hemorrhage whether primary or secondary. The study included 1004 patients with mean age of 10.4 years (range from 4 to 35 years). The first group (coblation tonsillectomy group) included 507 patients, age ranging from 4 to 35 years with mean age 15.1 year. This group included 277 female (54.6%) and 230 male (45.4%). The second group (conventional tonsillectomy group) included 497 patients, age ranging from 4 to 24 years and mean age 14.7 years. This group included 274 female (55.1%) and 223 male (44.9%). Coblation tonsillectomy offers significant advantages over dissection method with less operative time, decreased intraoperative blood loss, early restoration of daily activities and normal diet. However coblation tonsillectomy is associated with a higher incidence of secondary hemorrhage.

Abstract
BACKGROUND Tonsillectomy is a very common operation and is performed using various surgical methods. Coblation is a popular method because it purportedly causes less pain than other surgical methods. However, the superiority of coblation is unproven. OBJECTIVES To compare the effects of coblation tonsillectomy for chronic tonsillitis or tonsillar hypertrophy with other surgical techniques, both hot and cold, on intraoperative morbidity, postoperative morbidity and procedural cost. SEARCH METHODS The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2017, Issue 3); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 20 April 2017. SELECTION CRITERIA Randomised controlled trials (RCTs) of children and adults undergoing tonsillectomy with coblation compared with any other surgical technique. This review is limited to trials of extracapsular (traditional) tonsillectomy and excludes trials of intracapsular tonsil removal (tonsillotomy). DATA COLLECTION AND ANALYSIS We used the standard Cochrane methods. Our primary outcomes were: patient-reported pain using a validated pain scale at postoperative days 1, 3 and 7; intraoperative blood loss; primary postoperative bleeding (within 24 hours) and secondary postoperative bleeding (more than 24 hours after surgery). Secondary outcomes were: time until resumption of normal diet, time until resumption of normal activity, duration of surgery and adverse effects including blood transfusion and the need for reoperation. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS We included 29 studies, with a total of 2561 participants. All studies had moderate or high risk of bias. Sixteen studies used an adequate randomisation technique, however the inability to mask the surgical teams and/or provide adequate methods to mitigate the risk of bias put nearly all studies at moderate or high risk of detection and measurement bias for intraoperative blood loss, and primary and secondary bleeding. In contrast most studies (20) were at low risk of bias for pain assessment. Most studies did not report data in a manner permitting meta-analysis.Most studies did not clearly report the participant characteristics, surgical indications or whether patients underwent tonsillectomy or adenotonsillectomy. Most studies reported that tonsillitis (infection) and/or tonsillar hypertrophy (obstruction) were the indication for surgery. Seven studies included only adults, 16 studies included only children and six studies included both. Pain At postoperative day 1 there is very low quality evidence that patients in the coblation group had less pain, with a standardised mean difference (SMD) of -0.79 (95% confidence interval (CI) -1.38 to -0.19; 538 participants; six studies). This effect is reduced a SMD of -0.44 (95% CI -0.97 to 0.09; 401 participants; five studies; very low-quality evidence) at day 3, and at day 7 there is low quality evidence of little or no difference in pain (SMD -0.01, 95% CI -0.22 to 0.19; 420 participants; five studies). Although this suggests that pain may be slightly less in the coblation group between days 1 and 3, the clinical significance is unclear. Intraoperative blood loss Methodological differences between studies in the measurement of intraoperative blood loss precluded meta-analysis. Primary and secondary bleeding The risk of primary bleeding was similar (risk ratio (RR) 0.99, 95% CI 0.48 to 2.05; 2055 participants; 25 studies; low-quality evidence). The risk of secondary bleeding was greater in the coblation group with a risk ratio of 1.36 (95% CI 0.95 to 1.95; 2118 participants; 25 studies; low-quality evidence). Using the median of the control group as the baseline risk, the absolute risk in the coblation group was 5% versus 3.6% in the control group. The difference of 1.3% has a 95% CI of 0.2% lower in the coblation group to 3.5% higher. Secondary outcomes Differences in study design and data reporting precluded the identification of differences in the time to resumption of normal diet or activity, or whether there was a difference in the duration of surgery.Although we could not feasibly compare the costs of equipment or operative facility, anaesthetic and surgical fees across different healthcare systems we used duration of surgery as a proxy for cost. Although this outcome was commonly reported in studies, it was not possible to pool the data to determine whether there was a difference.Adverse events other than bleeding were not well reported. It is unclear whether there is a difference in postoperative infections or the need for reoperation. AUTHORS' CONCLUSIONS The coblation technique may cause less pain on postoperative day 1, but the difference is small and may be clinically meaningless. By postoperative day 3, the difference decreases further and by postoperative day 7 there appears to be little or no difference. We found similar rates of primary bleeding but we cannot rule out a small increased risk of secondary bleeding with coblation. The evidence supporting these findings is of low or very low quality, i.e. there is a very high degree of uncertainty about the results. Moreover, for most outcomes data were only available from a few of the 29 included studies.The current evidence is of very low quality, therefore it is uncertain whether or not the coblation technique has any advantages over traditional tonsillectomy techniques. Despite the large number of studies, failure to use standardised or validated outcome measures precludes the ability to pool data across studies. Therefore, well-conducted RCTs using consistent, validated outcome measures are needed to establish whether the coblation technique has a benefit over other methods. In the included studies we identified no clear difference in adverse events. However, given the rarity of these events, randomised trials lack the power to detect a difference. Data from large-scale registries will provide a better estimate of any difference in these rare outcomes.

Abstract
OBJECTIVE Suprastomal granulomas pose a persistent challenge for tracheostomy-dependent children. They can limit phonation, cause difficulty with tracheostomy tube changes and prevent decannulation. We describe the use of the coblator for radiofrequency plasma ablation of suprastomal granulomas in five consecutive children from September 2012 to January 2016. METHOD Retrospective case series at a tertiary medical center. RESULTS The suprastomal granuloma could be removed with the coblator in all 5 cases. Three were removed entirely endoscopically and 2 required additional external approach through the tracheal stoma for complete removal. There were no intraoperative or postoperative complications. One patient was subsequently decannulated and 2 patients have improved tolerance of their speaking valves. Two patients remain ventilator dependent, but their bleeding and difficulty with tracheostomy tube changes resolved. Three of the patients have had subsequent re-evaluation with bronchoscopy, demonstrating resolution or markedly decreased size of the granuloma. This technique is time efficient, simple and minimizes risks associated with other techniques. The relatively low temperature and use of continuous saline irrigation with the coblator device minimizes the risk of airway fires. Additionally, the risk of hypoxia from keeping a low fractional inspiratory oxygen level (FIO2) to prevent fire is avoided. The concurrent suction in the device decreases blood and tissue displacement into the distal airway. CONCLUSION Coblation can be used safely and effectively with an endoscopic or external approach to remove suprastomal granulomas in tracheostomy-dependent children. More studies that are larger and have longer follow-up are needed to evaluate the use of this technique.

Abstract
Objectives: This consecutive case series is presented to describe inside-out complete tonsillectomy and to assess its effects on postoperative pain and bleeding and its initial effectiveness in controlling recurrent sore throat and peritonsillar abscess formation. Methods: Bipolar electrosurgical scissors are used for bloodless resection of 90% of the tonsillar mass. During controlled resection, tonsil tissue is intentionally left at the superior and inferior poles and at the deepest part of the tonsillar fossa to provide coverage for nutrient arteries and the tonsillar plexus of veins. This tissue is then electrodesiccated and removed under direct vision and indirect mirror guidance to achieve complete tonsillectomy. Results: One hundred eighty-three consecutive tonsillectomies were performed by a single surgeon in a 16-month period, 47 of which were for the indication of recurrent sore throat (44) or recurrent peritonsillar abscess (3). Among these 47 children, there were 2 readmissions for dehydration. There were no immediate or delayed bleeding episodes. The average child required 4 days of narcotic pain medication. The mean annualized number of severe sore throats decreased from 5.24 before operation to 0.36 after operation (p <.0001, Student's paired t-test). There were no recurrent peritonsillar abscesses. Conclusions: Inside-out complete tonsillectomy achieves the surgical goal of complete tonsillectomy with the smallest possible wound and minimal injury to the surrounding tissue. The perioperative morbidity is markedly decreased compared to that of historical controls. The initial results suggest effectiveness similar to that of extracapsular tonsillectomy.

Abstract
Objectives: We performed a prospective study to evaluate the incidence of post-tonsillectomy hemorrhage (PTH) in adults and children who underwent Coblation tonsillectomy (CTE) under general anesthesia. Methods: The data of 63 adults and children (mean age, 21.8 years) were analyzed. Results: There were 7 episodes of considerable bleeding (11.1%) that required surgical treatment under general anesthesia in 6 patients, of whom 5 experienced secondary bleeding (>24 hours). Moreover, bleeding and massive swelling of the pharynx required surgical treatment and prolonged intubation (35 hours) in 1 patient. None of the patients received blood transfusions. There was no case with a lethal outcome. Less intense bleeding (clots; blood-tinged sputum) was observed in 17 patients (27%) who required readmission or prolonged inpatient observation, 1 of whom had previously undergone surgical treatment of PTH. However, these 17 patients had an uneventful clinical course. In total, 22 patients experienced minor or major forms of PTH (34.9%). Conclusions: At least in our hands, CTE dramatically increased the frequency of PTH. The high rate of secondary bleeding contrasts with our documented experience using conventional methods, ie, cold dissection and suture ligation, to achieve hemostasis (7.9% with CTE versus <0.8% with conventional methods). Therefore, at our institution, tonsillectomy with conventional instruments remains the method of choice.

Abstract
INTRODUCTION Radiofrequency microtenotomy is used to enhance healing by increasing vascularity in the degenerated tendon. In the present study, the effect of radiofrequency microtenotomy (Rf-mt) treatment on tendon degeneration was investigated. MATERIALS AND METHODS A total of 32 New Zealand rabbits were enrolled in the current study. Experimental degeneration was performed by injecting prostaglandin E1 (PGE1) into the bilateral Achilles tendons of rabbits. After excluding 4 rabbits with an infection on the injection site, 4 other rabbits were sacrificed to define the histopathologic changes in the tendons. The remaining 24 rabbits were divided into 2 groups: the control group and the Rf-mt group. In the control group, the Rf-mt device was only applied to the Achilles tendon without running the device. In the Rf-mt group, the Rf-mt device was applied bilaterally at the fourth energy level for 500ms to an area within 2cm proximal to the insertion site at 0.5cm intervals in order to form a grid. Six rabbits from each group were sacrificed at 6 and 12 weeks. The Achilles tendons were evaluated histopathologically by a modified Movin scale and by immunohistopathologic staining for vascular endothelial growth factor and type 4 collagen. RESULTS After the PGE1 injection, findings similar to chronic degenerative tendinopathy were observed. The Rf-mt group showed significant improvement in vascularity in the histopathological and immunohistochemical examination (P<0.05). However, there was no significant difference in healing between the control and Rf-mt groups (P>0.05). CONCLUSIONS Rf-mt treatment increases vascularity in degenerated tendons but does not create difference to facilitate the healing process comparing control group.

Abstract
Hemangiomas are lesions that are not present at birth. They manifest within first month of life, exhibit a rapid proliferative phase, and slowly involute to non-existent. Hemangiomas of the oral cavity are not common pathological entities, but the head and neck are common sites. Furthermore some time histologically lymphatic channels may be evident in hemangiomas, and then it will be categorized according predominant component, e.g.; hemangiolymphangiomas or lymphangiohemangiomas, vice versa is true for lymphangiomas. Most true hemangiomas involute with time, but 10-20% of true hemnagioma in completely involute and required post- adolescent ablative treatment. In the present article we are reporting a case of hemangiolypmangiomas of left buccal mucosa in an 18-year-old male patient. We have also reviewed various treatment modalities and their clinical implication.

Abstract
CONCLUSION The low temperature device did not show any advantages over the conventional high temperature electrocautery in terms of the postoperative pain, operation time, and complications in pediatric tonsillectomy. OBJECTIVE To compare post-tonsillectomy pain following the use of two different instruments with the same bipolar forceps techniques: low temperature quantum molecular resonance (QMR) device versus conventional high temperature electrocautery. METHODS Pediatric patients admitted from July 2008 through January 2009 were included. The participants underwent bilateral tonsillectomy; one side by the QMR device and the other by the bipolar electrocautery. The sides for each instrument were counterbalanced by the order of presentation. The postoperative pain was measured using the faces pain rating scale. RESULTS In all, 33 patients with a mean age of 7.6 years were enrolled. The postoperative pain, operation time, and complications in 33 sides dissected by the electrocautery and 33 sides by the QMR device were compared. The average operation times with each device were not statistically different. The mean ratings of the perception of pain related to each instrument were not different on operation day and postoperative day 1, day 4, and day 7 (p = 0.133, 0.057, 0.625, and 1.0, respectively). There was no postoperative complication in any of the patients.

Abstract
OBJECTIVE The current methods of management of tracheal stenosis have disadvantages and are controversial, therefore ideal experimental animal models for the further studies are required. The aim of this study was to establish a new model of canine tracheal stenosis by radiofrequency cauterization. METHODS The tracheal cartilage ring was injured by radiofrequency at the level of the sixth tracheal ring in 12 mongrel dogs. A fibrolaryngoscope was used to guide the procedure. The animals were observed after operation and examined after euthanasia. Endoscopic and histological examinations were undertaken to evaluate the progress of stenosis. The degree of stenosis was calculated using the formula: degree of stenosis=(initial lumen area-final lumen area)/initial lumen area × 100%. RESULTS Tracheal stenosis had developed in all dogs by the 21st day post operation. Costal retraction was observed in all dogs after the 18th day post operation. At the end of the study, gross and endoscopic examinations showed that stenosis had been induced to a satisfactory degree and without any complications. The median of the degree of stenosis was 92%, with a range of 84-94%. Histological examination showed that cartilage was damaged and that granulation tissue and collagen fibres had formed. CONCLUSIONS The model of canine tracheal stenosis induced by radiofrequency cauterization is a relatively simple, reliable, and reproducible animal model. This model may be useful in the development of new methods of treatment for tracheal stenosis.

Abstract
This randomized double blind study was conducted prospectively to determine whether coblation tonsillectomy fared better than the conventional dissection method in terms of postoperative pain, bleeding, and rapidity of healing in adult Indian patients undergoing tonsillectomy. Sixty adult patients undergoing tonsillectomy for benign indications were randomized to have one tonsil removed by subcapsular radiofrequency ablation method and the other by conventional dissection method. The operative time and blood loss was noted for each side. Patients were evaluated at 6, 12, 24, 48, 72 h and then on 7th and 20th postoperative day for postoperative pain (by visual analog scale), bleeding, and tonsillar fossa healing. Statistical comparison was done using appropriate tests. The two groups were demographically matched. It took longer to perform the coblation procedure (15 vs 11 min) (P > 0.05). The operative blood loss on the radiofrequency side was 11 ml, vs 34 ml on the conventional side (P = 0.009). 77% patients said that the coblation side was less painful for the overall 20-day recovery period. There were significant differences seen at 6, 12, 24, 48, and 72 h in terms of postoperative pain scores. Beyond that, the pain was consistently less on the coblation side, but the difference was not significant. There was no case of reactionary or secondary hemorrhage in either arm. The healing took longer on the radiofrequency side. Coblation tonsillectomy is an easy to learn technique with significantly reduced operative blood loss and postoperative pain. Longer operative times maybe further reduced with experience.

Abstract
AIMS Investigate the influence of operative technique on post-operative morbidity and the systemic inflammatory response after tonsillectomy. In addition, our aim was to compare the systemic inflammatory reaction, post-operative pain severity, and required time before the resumption of normal physical activity between two groups of tonsillectomized children and to correlate characteristics of the systemic inflammatory reaction to post-operative morbidity. PARTICIPANTS AND METHODS This prospective, randomized, and single-blind study included 100 children between the ages of 3-16 years and who were scheduled for a tonsillectomy at our department for chronic tonsillitis and/or respiratory obstruction. The children were randomly assigned into one of two groups: either a conventional tonsillectomy with bipolar diathermy coagulation or a radiofrequency tonsillectomy procedure; both groups had a 14-day follow-up. We investigated the severity and duration of postoperative pain (based on the use of analgesics during the postoperative period), the postoperative day that they resumed normal physical activity, and the rate of postoperative hemorrhage. In order to assess the systemic inflammatory response, serum C-reactive protein (CRP) levels were measured before the surgery and seven days after the procedure. RESULTS After the surgery CRP levels increased to a statistically significant level (t = -4.7; p < 0.001) in conventional tonsillectomy group. There was a statistically significant correlation between increased blood CRP levels after the surgery and the level of post-operative analgesic consumption, which was based on an increased number of analgesic applications (r = 0.28; p < 0.01) and a greater number of days in which analgesics were consumed (r = 0.26; p < 0.01). There was also a correlation between increased blood CRP levels and a longer required time to resume normal physical activities (r = 0.30; p < 0.01). CONCLUSION Post-operative morbidity after tonsillectomy appears to depend on the systemic inflammatory response to surgery. This response is "technique-related," wherein a less-aggressive surgical technique produces a weaker post-operative inflammatory response and less post-operative morbidity.

Abstract
After the surgical procedure of tonsillectomy, hemorrhage ranks among its serious postoperative complications. In this systematic review, we analyze hemorrhage following tonsillectomies performed using the coblation technique. 24 prospective, randomized, and controlled studies were included in the meta-analysis. Data of 796 patients who had undergone coblation tonsillectomy were analyzed. Hemorrhages occurred in 33 patients: 2 classified as primary and 26 as secondary hemorrhages. 5 could not be classified into either group. Overall, the total hemorrhage rate for the coblation procedure was 4.1% with a 95% confidence interval from 2.8 to 5.5%. The overall hemorrhage rate of 4.1% found in this meta-analysis shows that coblation is a safe and effective technique for tonsillectomies with a secondary bleeding rate similar to what is reported for comparable techniques such as bipolar diathermia.

Abstract
OBJECTIVES To compare the efficacy and safety of radiofrequency and monopolar electrocautery tonsillectomy, regarding operation duration and tonsillectomy morbidity, including post-operative pain and haemorrhage and tonsillar fossa healing, in patients with recurrent chronic tonsillitis. STUDY DESIGN A prospective, randomised, double-blind, controlled clinical study. METHODS Fifty patients aged over 10 years who required tonsillectomy were randomly assigned to have one tonsil removed by radiofrequency and the other by monopolar electrocautery. Operation duration, post-operative haemorrhage, post-operative pain and tonsillar fossa wound healing were compared. RESULTS The mean +/- standard deviation of the operation duration required for the radiofrequency method was significantly longer than that for monopolar electrocautery: 8.1 +/- 1.6 minutes vs 7.3 +/- 1.5 minutes, respectively (p = 0.034). Post-operative haemorrhage was observed in only three patients (13.6 per cent). Inter-group analysis showed no significant differences in post-operative pain scores for the radiofrequency vs monopolar electrocautery methods (3.7 +/- 1.6 vs 3.3 +/- 1.4, respectively; p < 0.126). Inter-group analysis showed that tonsillar fossa wound healing scores evaluated on the fifth, 10th and 14th post-operative days were significantly higher in the radiofrequency group compared with the monopolar electrocautery group (p < 0.001). CONCLUSION The present study results indicated that monopolar electrocautery tonsillectomy was superior to radiofrequency tonsillectomy in terms of post-operative tonsillar fossa wound healing; however, both techniques were comparable in terms of post-operative pain.

Abstract
OBJECTIVE To compare the postoperative recovery of patients who undergo intracapsular to subcapsular Coblation tonsillectomy. STUDY DESIGN AND SETTING This was a prospective, randomized, double-blinded study. A total of 69 children, aged 2 to 16 years, were randomized to intracapsular (n = 34) or subcapsular (n = 35) tonsillectomy. The Coblation technique was used with both groups. Outcomes measures were assessed on postoperative day 1 or 2 and 5 or 6. These included child and parental rating of pain with the Wong Faces pain scale, analgesic use, oral intake, and activity level. RESULTS Intracapsular tonsillectomy patients had similar levels of pain to subcapsular tonsillectomy patients on day 1 or 2. However, at day 5 or 6, intracapsular tonsillectomy patients had significantly less pain than the subcapsular tonsillectomy patients. Intracapsular patients ate more and were more active at both time points. CONCLUSION AND SIGNIFICANCE Children with obstructive sleep apnea who undergo tonsillectomy demonstrate better postoperative recovery after intracapsular tonsillectomy. The intracapsular versus subcapsular difference may be best appreciated at a delayed time point (day 5 or 6) rather than early (day 1 or 2).

Abstract
BACKGROUND AND OBJECTIVES Tonsillectomy is frequently associated with postoperative pain of considerable duration, which is usually accompanied by the substantial consumption of both opioid and non-opioid analgesics. Despite the use of different surgical and anaesthetic techniques in the search for safe and effective post-tonsillectomy pain relief, this problem remains a clinical dilemma. The aim of the current study was to evaluate the potential effects of topically administered ketamine and morphine by an oral rinse into the tonsillar fossae. METHODS In all, 60 children, 15 for each group, aged between 3 and 12 yr scheduled for tonsillectomy were randomly assigned to one of four groups. Study drugs were administered to both tonsillar fossae for 5 min. Group K received 0.4 mL (20 mg) ketamine in 10 mL artificial saliva, Group KM received 0.4 mL (20 mg) ketamine + 5 mL (20 mg) 4 per thousand morphine aqueous solution in 5 mL artificial saliva, Group M received 5 mL (20 mg) 4 per thousand morphine aqueous solution in 5 mL artificial saliva, Group C received only 10 mL artificial saliva. Postoperative pain, nausea, vomiting, sedation and bleeding were evaluated. RESULTS Pain scores were higher in the control group at arrival in the recovery ward (P < 0.05). Morphine and ketamine groups had longer effective analgesia time than the morphine + ketamine and control groups. The 24-h analgesic consumption was significantly higher in the control group. CONCLUSION Topical ketamine and morphine seems to be a safe and easy analgesic approach for decreasing adenotonsillectomy pain.

Abstract
AbstractIntroduction:Coblation tonsillectomy is a relatively recently introduced surgical technique which attempts to bridge the gap between ‘hot’ and ‘cold’ tonsillectomy methods.Aim:To compare coblation tonsillectomy with three commonly used surgical techniques: cold dissection–ligation, monopolar electrocautery and CO2 laser.Materials and methods:A prospective, randomised, double-blinded clinical trial was undertaken of 60 adult patients divided into three equal study groups. Patients in each group were randomly assigned to have one tonsil removed with coblation and the second with one of the other three tonsillectomy techniques. Ten randomly selected tonsils resected by each method were sent for histopathological evaluation.Results:Coblation was significantly faster to perform than laser and produced significantly less intra-operative blood loss than both the dissection–ligation and laser techniques. Subjective visual analogue scale comparisons showed a non-significant pain score difference between coblation and dissection–ligation on most post-operative days. Coblation produced consistently highly significantly (p < 0.001) less pain, compared with electrocautery up to the 12th post-operative day and laser up to the 10th post-operative day. There was no significant difference in tonsillar fossa healing, comparing coblation to both dissection–ligation and laser techniques. Monopolar electrocautery produced significantly slower healing than coblation after 7 post-operative days, with no significant difference after 15 post-operative days. Histopathological evaluation showed that coblation inflicted significantly less thermal tissue injury than either electrocautery (p = 0.001) or laser (p = 0.003).Conclusions:In adult patients, coblation tonsillectomy offers some significant advantages in terms of post-operative pain and healing, compared with other tonsillectomy techniques.

Abstract
BACKGROUND Tonsillectomy is one of the most commonly performed surgical procedures. There are several operative methods currently in use, but the superiority of one over another has not been clearly demonstrated. OBJECTIVES To assess the effectiveness of coblation tonsillectomy compared with other surgical techniques in reducing morbidity. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2006), MEDLINE (1966 to 2006) and EMBASE (1974 to 2006). The date of the last search was December 2006. SELECTION CRITERIA Randomised controlled trials of children and adults undergoing tonsillectomy by means of coblation compared with any other surgical technique for removal of the tonsils. Trials were assessed for methodological quality according to the method outlined in the Cochrane Handbook for Systematic Reviews of Interventions 4.2.6. DATA COLLECTION AND ANALYSIS Data were extracted using standardised data extraction forms. Authors were contacted where additional data were required. MAIN RESULTS Nineteen studies were identified with sufficient data for further assessment. Four of these were excluded because intra-capsular tonsillectomy (i.e. tonsillotomy) rather than sub-capsular tonsillectomy was performed, and a further five studies because tonsils rather than participants were randomised. One further study was excluded because, although describing itself as a randomised trial, its participants turned out not to have been randomised to their intervention groups. Nine trials met the inclusion criteria, comparing coblation to other tonsillectomy techniques. All but two studies were of low quality and therefore a meta-analytical approach was not appropriate. In most studies, when considering most outcomes, there was no significant difference between coblation and other tonsillectomy techniques. AUTHORS' CONCLUSIONS In terms of postoperative pain and speed and safety of recovery, there is inadequate evidence to determine whether coblation tonsillectomy is better or worse than other methods of tonsillectomy. Evidence from a large prospective audit suggests that it has been associated with a higher level of morbidity, in terms of postoperative bleeding. Large, well-designed randomised controlled trials supplemented by data from large prospective audits are needed to produce information on effectiveness and morbidity respectively.

Abstract
The purpose of this study is to determine if bipolar radiofrequency energy (bRFE) can enhance delayed surgical repair of acute supraspinatus tendon tears. Bilateral supraspinatus tendon tears were created in 42 Sprague-Dawley rats and repaired at 6 weeks either with or without bRFE augmentation. There were 8 control (sham) rats. Treatment rats were euthanized at 4, 8, and 12 weeks after repair. All specimens underwent biomechanical and histologic evaluation. Compared with standard repair, bRFE-treated repairs showed a greater average maximum stress (8.475 N/m2 versus 3.95 N/m2) at 12 weeks, which was not significant (P < .11). The mode of failure was by humeral fracture in 57.14% > with bRFE versus 14.29% without bRFE. Histologically, both standard and bRFE-treated repairs were indistinguishable from controls at 12 weeks. The use of bRFE showed no definitive effect on delayed repair of acute rat rotator cuff tears.

Abstract
BACKGROUND Controversy surrounds the question of which technique should be preferred for tonsillectomy in order to reduce postoperative morbidity in terms of pain, bleeding, activity and return to normal diet. This study reviews the current literature on coblation tonsillectomy (CTE). MATERIALS AND METHODS All studies published in peer-reviewed journals reporting postoperative morbidity following CTE until July 2006 were included in our study. RESULTS A total of 21 studies matched our search criteria but there were excluded from further analysis because coblation was used only for volume reduction of the tonsils. Reduced morbidity was registered in eight studies, two could not identify any difference and five studies reported an increased postoperative morbidity. Seven different surgical procedures were compared in 17 studies to CTE. The patients were not followed-up in four studies and the follow-up exceeded 1 week in nine studies only. Wound inspection was performed in four studies and a better wound healing reported in two of these, but by the same authors. Postoperative bleeding requiring surgical treatment under general anaesthesia occurred with an incidence of 0% to 11.5%. Secondary bleeding (>24 h) prevailed in all but two studies. Postoperative pain was evaluated in ten studies with conflicting results. CONCLUSIONS The design of the current studies varies in size, age distribution, indications for surgery, the surgical techniques compared and follow-up. The results are heterogenous and further evidence is still required to show that CTE is a safe alternative. Therefore, calculation of cost-effectiveness of a commonly performed expensive CTE as a new standard technique is currently impossible.

Abstract
BACKGROUND Tonsillectomy is one of the commonest surgical procedures, with postoperative pain being an important source of morbidity. Coblation (cold ablation) is a new technique for tonsillectomy, promoted by claims of reduced postoperative pain levels. This study was designed to compare postoperative pain after tonsillectomy using coblation and tonsillectomy using the standard dissection techniques. METHODS Twenty adult patients underwent tonsillectomy, each having one randomly selected tonsil removed by dissection and the other removed by coblation. For each side, subjective pain levels were recorded on a daily basis for 10 postoperative days, using a visual analogue scale. RESULTS Coblation tonsillectomy was significantly less painful than dissection tonsillectomy on day 1 (P < 0.001), day 2 (P = 0.003) and day 3 (P = 0.018). For all subsequent postoperative days, there was no significant difference in pain levels between the techniques. CONCLUSION Coblation tonsillectomy causes significantly less pain during the first three postoperative days, when compared with dissection tonsillectomy. No demonstrable benefit was shown on days 4-10. The beneficial effects of coblation on early postoperative pain make it a potentially attractive technique for day-case tonsillectomy in adults with recurrent or chronic tonsillitis.

Abstract
OBJECTIVES To determine if the coblation tonsillectomy (subcapsular dissection) results in less postoperative pain, equivalent intraoperative blood loss, equivalent postoperative hemorrhage rates, and faster healing compared with tonsillectomy was performed using unipolar electrocautery in adult patients. STUDY DESIGN The authors conducted a prospective clinical trial. METHODS Forty-eight patients underwent tonsillectomy and were randomly assigned to have one tonsil removed with coblation and the other with unipolar electrocautery. Outcome measures included time to remove each tonsil, intraoperative blood loss, patient-reported pain, postoperative hemorrhage, and amount of healing 2 weeks after surgery. RESULTS Mean time to remove a single tonsil with coblation and electrocautery was 8.22 minutes and 6.33 minutes, respectively (P = .011). Mean intraoperative blood loss for each technique was less than 10 mL. Postoperative pain was significantly less with coblation as compared with electrocautery: 18.6% less painful during the first week of recovery. Seventy percent of blinded patients identified the coblation side as less painful during the overall 14-day convalescent period. Postoperative hemorrhage rates (2.1% for coblation and 6.2% for electrocautery) were not significantly different. No difference in tonsillar fossa healing was observed between the two techniques 2 weeks after surgery. During nine of the 48 surgeries, wires on the tip of the coblation handpiece experienced thinning to the point of discontinuity while removing a single tonsil. CONCLUSIONS Coblation subcapsular tonsillectomy was less painful than electrocautery tonsillectomy in this 48-patient group. On average, intraoperative blood loss was less than 10 mL for both techniques. Postoperative hemorrhage rates and the degree of tonsillar fossa healing were similar between the two techniques. The coblation handpiece experienced degradation of vital wires in 18% of cases necessitating the use of a second, new handpiece.

Abstract
OBJECTIVE Tonsillectomy is frequently associated with post-operative pain of considerable duration. The aim of the current study is to corroborate our previous observational data by conducting a prospective double-blind placebo-controlled randomized clinical trial to determine the potential effect of pre-incision infiltration of local anesthesia on post-operative pain after tonsillectomy. DESIGN Randomized double-blind controlled clinical trial. SETTING Tertiary care facility in Beirut, Lebanon. PATIENTS Ninety patients who underwent tonsillectomy allocated evenly in three groups. INTERVENTIONS Pre-incision infiltration of 1.5 local anesthetic mixture in each tonsil was performed in conjunction with general anesthesia (infiltration, n=30). Pre-incision infiltration of 1.5 ml of 0.9% of normal saline was applied with general anesthesia (placebo, n=30). GA received only general anesthesia. OUTCOME MEASURES Post-operative pain at rest, eating soft diet, jaw opening at 0, 6, 12, and once daily for the 10-day follow-up period, hemodynamic stability, hospital stay, parent and surgeon satisfaction, ear pain and analgesics consumption were assessed. RESULTS Hemodynamic stability was maintained during pre, per and post-operation. 93.1% of infiltration group left the hospital the same day compared to 60% in placebo groups and 41.4% in general anesthesia group (p=0.001). Surgeon's satisfaction was significantly higher in infiltration group compared to placebo and general anesthesia groups (p=0.001). Parent's satisfaction was significantly higher in infiltration group (89.65%) compared to general anesthesia group (13.8%) and placebo group (36.7%) (p=0.001). The average pain scores at rest, on jaw opening and when eating soft diet were significantly lower in infiltration group compared to placebo group and general anesthesia group (p<0.05). Analgesic consumption in placebo and general anesthesia groups were significantly higher compared to infiltration group (p<0.05). CONCLUSION This modified pre-incision infiltration of anesthetic mixture combined with general anesthesia reduces significantly post-tonsillectomy pain in children and provides a more rapid return to normal activity compared to general anesthesia alone or in combination with a placebo infiltration.

Abstract
OBJECTIVE We previously compared radiofrequency (Evac) tonsillotomy with monopolar electrosurgical (Bovie) tonsillectomy and showed significantly less pain with the Evac. Tonsillotomy leaves a cuff of tonsil behind, the significance of which is unknown. We hypothesize that Evac tonsillectomy also is less painful than Bovie tonsillectomy. STUDY DESIGN AND SETTING We compared Evac (ENTec Evac 70; ArthroCare, Sunnyvale, CA) and Bovie tonsillectomy in a prospective, blinded fashion. Each participant had 1 tonsil removed by each device. We recorded, by side, the surgical time, blood loss, operative difficulty, pain (postoperative days 1, 3, 5, 7, 10, and 14), and the side that each patient preferred. RESULTS Data were analyzed for 17 patients. They reported significantly less pain with the Evac (P < 0.036, F = 5.87). The Evac was preferred by 12 of 14 patients. CONCLUSION Evac tonsillectomy is significantly less painful than Bovie tonsillectomy. Patients blinded to treatment preferred the Evac technique. SIGNIFICANCE The Evac device decreases postoperative pain.

Abstract
This article reviews the various treatments currently available for obstructive sleep apnea and discusses some newer and more controversial therapies. Decisions regarding the best treatment should be aimed at relieving the unique levels of obstruction in each patient. Increased controlled outcome trials will be needed to assess the success of each therapy in certain subpopulations in comparison with CPAP. As these data become available, the roles of each therapy will become clearer in treating this major health problem.

Abstract
OBJECTIVE To compare the postoperative recovery of patients receiving Coblation-assisted (Arthrocare, Sunnyvale, CA) intracapsular tonsillectomy with that of patients receiving traditional subcapsular electrocautery tonsillectomy. STUDY DESIGN AND SETTING This was a prospective, randomized, double-blinded, controlled study. One hundred one children, aged 2 to 16 years, were randomized to Coblation or to conventional electrocautery tonsillectomy. Only patients with the operative indication of obstructive sleep apnea were entered into the study. Intracapsular tonsillectomy was performed on the Coblation group, and traditional subcapsular dissection was performed on the electrocautery group. Adenoidectomy was performed with the curette in both groups. Outcome measures were assessed on days 1, 3, and 5 after surgery. These included child and parental rating of pain by using the Wong Faces pain scale, analgesic use, oral intake, and activity level. Patients, parents, and the nurse practitioner obtaining the outcome data were blinded to treatment arm. RESULTS Treatment groups were similar in age, gender, and weight. Surgical time and estimated blood loss were similar. There were no complications in either group. Coblation patients had less pain and greater oral intake at all 3 time points. Percentage of normal activity level returned to >70% earlier and more frequently in Coblation patients. There was slightly decreased analgesic use on postoperative day 5 in the Coblation group. CONCLUSIONS AND SIGNIFICANCE Children with obstructive sleep apnea undergoing tonsillectomy and adenoidectomy demonstrate significantly better postoperative recovery after Coblation-assisted intracapsular tonsillectomy.
