    Input: OBJECTIVE Tonsillectomy has been described using a number of techniques . Recently Coblation Technology has been used to remove tonsils with anecdotal evidence of a reduction in post-operative morbidity . In this study we aim to see if there is any difference in post-operative pain , tonsillar fossae healing and return to a normal diet performing  tonsillectomy  , using tissue coblation compared with st and ard bipolar dissection . METHODS A double blind r and omised control trial to compare the technique of tissue coblation with st and ard bipolar dissection to remove tonsils in 38 children on the waiting list for tonsillectomy , with a history of chronic tonsillitis or obstructive tonsils . RESULTS A significant reduction in post-operative pain was found in the children whose tonsils were removed by tissue coblation ( P<0.0001 ) . More rapid healing of the tonsillar fossae was found in the coblation group . Children who had their tonsils removed by coblation were found to return to their normal diet far sooner than those who underwent bipolar dissection . There were no episodes of primary or secondary haemorrhage in either group . CONCLUSIONS This new technique using tissue coblation for tonsil removal offers significant advantages in the post-operative period , with rapid return to a normal diet and a drastic reduction in analgesic requirements following the surgery Objectives : The purpose of this study was to establish if children experienced any difference in pain , between coblation tonsillectomy and coblation tonsillotomy OBJECTIVES : The objective of this study was to compare the safety , difficulty of removal , and postoperative pain profile of radiofrequency ablation versus st and ard electrocautery removal of tonsils . STUDY DESIGN AND SETTING : A prospect i ve , blinded study was design ed to remove 1 tonsil with each of the 2 methods . Time of operation , estimated blood loss , difficulty of operation , postoperative pain , rate of postoperative hemorrhage , and the patient 's preferred technique were evaluated . RESULTS : The operating time was significantly longer ( P < 0.007 ) and the patients reported significantly less pain ( P < 0.001 ) with radiofrequency ablation . There were no differences in blood loss , difficulty of operation , or postoperative hemorrhage rates . The patients preferred the radiofrequency ablation technique ( P < 0.001 ) . CONCLUSION : Radiofrequency ablation is a viable method to remove tonsillar tissue . Operating time for this procedure will likely decrease with experience . There was significantly less pain reported with radiofrequency ablation compared with st and ard electrocautery . ( Otolaryngol Head Neck Surg 2004;130:300–5 . Tonsillectomy has been performed by a number of techniques . This double blind r and omized controlled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis . A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation . There were no episodes of primary or secondary haemorrhage on either side . This new technique for tonsil removal warrants further study OBJECTIVE To determine the efficacy of intracapsular tonsillectomy using low-temperature plasma excision for improving the quality of the postoperative experience and for treating obstructive symptoms through 12 months postoperatively . DESIGN Prospect i ve , r and omized , controlled , single-blind study . SETTING Multiple private or institutional otolaryngology clinics . PATIENTS Fifty-five children ( aged 3 - 12 years ) with obstructive tonsillar hypertrophy . INTERVENTION Patients were r and omly assigned and blinded to undergo either intracapsular tonsillectomy using low-temperature plasma excision ( n = 27 ) or total tonsillectomy using conventional electrosurgery ( n = 28 ) . MAIN OUTCOME MEASURES Operative data , 14-day recovery variables , and obstructive symptoms were prospect ively collected through 12 months . RESULTS During the first 14 days , significantly fewer children in the intracapsular group reported nausea ( P = .01 ) or lost weight ( P = .003 ) . The intracapsular group had a significantly faster resolution of pain ( P = .01 ) , had an earlier return to a normal diet ( P = .004 ) , ceased taking pain medication sooner ( P = .002 ) , and returned to normal activity sooner ( P = .04 ) . Postoperatively , the intracapsular group had more residual tonsil tissue than the total tonsillectomy group ( P = .002 for the 3- and 12-month visits ) . However , the incidence of recurring obstructive symptoms , pharyngitis , and antibiotic use was similar in both treatment groups during the 12 months . CONCLUSIONS Postoperative morbidity normally associated with traditional ( total ) tonsillectomy was significantly reduced after intracapsular tonsillectomy using low-temperature plasma excision . The residual tonsillar tissue associated with this technique was of no clinical consequence Coblation  tonsillectomy  has shown promising results with respect to postoperative pain when compared with other techniques . Our study was design ed to compare this technique with bipolar scissor tonsillectomy .  Forty adult patients with a history of chronic or recurrent tonsillitis referred for st and ard tonsillectomy were recruited and r and omized into two groups . Twenty were operated with Coblator and 20 with bipolar scissors .  Exclusion criteria were a history of quinsy , bleeding disorder , or any major health problems . All participants completed the study . Postoperative pain , return to normal diet , and estimated need for sick leave were utilized as parameters . Data on operative time , difficulty of tissue removal , and hemostasis were also analyzed . Operative time was longer ( P < 0.001 ) and tissue removal as well as hemostasis control were more difficult ( P = 0.005 , P = 0.013 ) with Coblator than with bipolar scissors . Participants in Coblator group assessed higher pain scores 1 and 3 h postoperatively ( P = 0.044 , P = 0.036 ) . From the time of extubation , patients had access to an opioid ( fentanyl ) via a self-controlled analgesia device . The number of doses of analgesics needed during the hospital stay was significantly higher in the Coblator group ( P = 0.020 ) . During the 14-day follow-up , no significant differences were found in pain scores , return to solid food or subjective working ability between the groups . Considering the overall outcome of the patients the results did not favor coblation technique over bipolar scissors BACKGROUND Quantum molecular resonance coagulation is an innovative technology that uses molecular resonance to cut and coagulate precisely , cleanly , and hemostatically at low tissue temperature levels . This technology offers a new possibility for tonsillectomy . OBJECTIVES To compare molecular resonance ( MRT ) with coblation ( CAT ) devices for pediatric tonsillectomy . STUDY DESIGN Prospect i ve , two-group , r and omized trial in a tertiary care pediatric institution . One hundred fifty-seven children for whom tonsillectomy was indicated were r and omly assigned to receive MRT ( n = 79 ) or CAT ( n = 78 ) . Main outcome measures included intraoperative time , blood loss , postoperative pain , and weight loss . Histopathologic examination was performed on all excised tonsils . Patients , parents , and pathologist were blinded to surgical modality . RESULTS Histopathologic evaluation revealed significantly reduced thermal injury with MRT than with CAT ( 43 microns vs. 126 , respectively , P < .001 ) , and was statistically associated with reduced muscular , blood vessel , and nerve fiber damage . No intraoperative blood loss was observed in patients following MRT . Statistically significant reduced pain scores were related to the MRT ( P < .002 ) . In addition , the MRT method showed a quick return to normal diet with even weight gain during the 10-day postoperative period . One child in the CAT group experienced delayed bleeding and required readmission . CONCLUSIONS Molecular resonance for pediatric tonsillectomy result ed in significantly reduced histopathologic thermal injury and lower pain scores compared with coblation . Further studies are advised to support these data OBJECTIVE : To compare the postoperative recovery of patients who undergo intracapsular to subcapsular Coblation tonsillectomy .  STUDY DESIGN AND SETTING : This was a prospect i ve , r and omized , double-blinded study . A total of 69 children , aged 2 to 16 years , were r and omized 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 ) OBJECTIVE To compare plasma-mediated ablation ( PMA ) with monopolar electrosurgery ( MES ) for pediatric tonsillectomy . DESIGN Prospect i ve , r and omized , blinded study . SETTING Academic children 's hospital . PARTICIPANTS Thirty-four children , aged 4 to 7 years . INTERVENTIONS Tonsillectomy by means of PMA ( n = 17 ) or MES ( n = 17 ) . OUTCOME MEASURES We measured surgical efficacy , estimated blood loss , and surgical time during tonsillectomy and morphine use , immediate postoperative pain , and recovery scores after tonsillectomy . Parents recorded recovery of normal diet and activity and their own return to work for 10 days after surgery . Histopathologic evaluation of excised tonsils was performed . We review ed medical records and attempted follow-up telephone contact . RESULTS With no significant difference in blood loss compared with MES , PMA was effective for tonsillectomy . Performance of PMA took longer ( 24 vs 16 minutes ; P = .002 ) . Results of histopathologic evaluation showed less thermal injury with PMA than with MES ( P = .03 ) . Morphine consumption , pain , and recovery scores were equivalent between groups . We found no significant difference in recovery of normal diet and activity or parental return to work .  Patients undergoing PMA  had a greater number of perioperative complications than those undergoing MES , including 2 patients in the PMA group ( compared with none in the MES group ) who required unplanned admission for postoperative airway obstruction . CONCLUSIONS Plasma-mediated ablation for pediatric tonsillectomy result ed in less histopathologic thermal injury than MES , but did not show a statistically faster recovery to normal activity and diet or parental return to work . In addition , PMA took longer to perform , and had more complications . Therefore , PMA should not replace MES for pediatric tonsillectomy . The reduced thermal injury with PMA supports investigation into other means of using plasma ablation to treat tonsillar hypertrophy 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 prospect i ve clinical trial . METHODS Forty-eight patients underwent tonsillectomy  and were r and omly 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 h and piece 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 h and piece experienced degradation of vital wires in 18 % of cases necessitating the use of a second , new h and piece Objectives : The aim of this study was to compare postoperative symptoms 
    Output:
    
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
