Paediatric coblation tonsillectomy.

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 standard bipolar dissection. METHODS: A double blind randomised control trial to compare the technique of tissue coblation with standard 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.     

A pilot randomized controlled trial of coblation tonsillectomy versus dissection tonsillectomy with bipolar diathermy haemostasis.

OBJECTIVES: To compare postoperative recovery in children between 4 and 12 years undergoing tonsillectomy, using either coblation tonsillectomy or dissection tonsillectomy with bipolar diathermy haemostasis. DESIGN: A prospective, single blind, randomised controlled trial. SETTING: ENT clinic, University Teaching Hospital. PARTICIPANTS: Forty paediatric patients, aged between 4 and 12 years and between 16 and 60 kg in weight with standard indication for tonsillectomy. METHODS: Patients were randomly allocated to either coblation tonsillectomy or dissection tonsillectomy groups. Patients, parents, and nurses were blinded for operation method. Parents were asked to fill out a postoperative diary from 1 to 10 days. MAIN OUTCOME MEASURES: Primary outcomes were scored for postoperative pain, nutrition, activity, and use of analgetics for each of the 10 postoperative days. Secondary outcomes were estimated from the nurses' postoperative data and 10-day follow-up statistics regarding crossing of the two-score limit. RESULTS: The groups were statistically comparable by age, weight and operation type. There was no significant difference in operation time in two groups. Intra-operative bleeding was significantly less in the coblation group. Statistically significant differences between dissection tonsillectomy and coblation tonsillectomy were found in the day when a score of two of five was passed in pain scores (9.6 versus 6.2), nutrition scores (8.9 versus 6.6), activity score (8.4 versus 6.6) and medicine intake (9.4 versus 6.4), We found parallelism, between regression lines, that indicates better postoperative life quality for the coblation tonsillectomy group and approximately 2 days' shorter recovery time. CONCLUSION: In our pilot study, patients undergoing coblation tonsillectomy reported less pain, quicker return to normal diet, quicker return to normal activity, and less use of analgetics over a 10-day period than patients undergoing dissection tonsillectomy. Our results indicate that the recovery period for coblation tonsillectomy was approximately 2 days shorter and demonstrated less morbidity.     

Cold dissection versus coblation-assisted adenotonsillectomy in children

OBJECTIVE: To compare intraoperative efficiency and postoperative recovery between cold dissection adenotonsillectomy (CDA) and coblation-assisted adenotonsillectomy (CAA). METHODS: A prospective, randomized, single-blind trial of pediatric patients aged 2 to 16 years undergoing adenotonsillectomy was conducted. Patients were randomized to undergo either CDA or CAA. Measured intraoperative parameters included surgical duration and intraoperative blood loss. Measured postoperative parameters included a 14 day caregiver questionnaire that recorded a daily pain rating using the Wong-Baker FACES pain scale, pain medication use, days to return to a normal diet, and days to return to a normal caregiver routine. Postoperative complications were also recorded. Intraoperative and postoperative measures were statistically compared between groups. RESULTS: Forty-six children with a mean age of 6.7 years (23 CDA and 23 CAA) were randomized and completed the study. Mean age and sex distributions were similar between groups (P > .05). Surgical times were significantly shorter for the CAA group versus the CDA group (11.2 min vs. 17.0 min, P < .001). Intraoperative blood loss was statistically lower for both the adenoidectomy and tonsillectomy portions of the procedure for the CAA group versus the CDA group (P < .001 and P < .001, respectively). There was no statistically significant difference in reported daily pain scores between groups (P = .296, analysis of variance). Both groups returned to normal diet (P = .982), and caregivers returned to their normal routine on similar postoperative days (P = .631). CONCLUSIONS: CAA offers better operative speed and intraoperative hemostasis as compared with CDA. However, CAA does not result in poorer postoperative pain scores or recoveries despite these intraoperative advantages.     

低温等离子刀、超声刀及传统方式行扁桃体切除术的比较

Coblation tonsillectomy versus dissection tonsillectomy: postoperative hemorrhage

OBJECTIVES/HYPOTHESIS: Coblation tonsillectomy is a recently introduced surgical technique. To measure its benefits against traditional tonsillectomy techniques, it is necessary to compare their complication rates. The study aims to identify differences in reactionary and secondary hemorrhage proportions, comparing coblation with dissection tonsillectomy. STUDY DESIGN: Prospective observational cohort study. METHODS: Rates of reactionary and delayed postoperative hemorrhage were measured, comparing 844 coblation tonsillectomies with a control group of 743 tonsillectomies performed by blunt dissection with bipolar diathermy hemostasis. RESULTS: The secondary hemorrhage rate with coblation-assisted tonsillectomy was 2.25% compared with 6.19% in the control group (P <.05). The rate of secondary hemorrhage in children following coblation tonsillectomy was 0.95% compared with 4.77% in the control group (P <.05). The difference was also significant (P <.05) in the adult population (4.40% vs. 8.81%, respectively). No difference was found in the reactionary hemorrhage proportions. CONCLUSION: In the study, coblation tonsillectomy was associated with a lesser incidence of delayed hemorrhage, more significantly in the pediatric population. The new technique using tissue coblation for tonsil dissection offers significant advantages in the postoperative period compared with dissection tonsillectomy with bipolar diathermy hemostasis. Coblation is associated with less postoperative pain and early return to daily activities. Also, there are fewer secondary infections of the tonsil bed and significantly lower rates of secondary hemorrhage with coblation. These results and the disposable nature of the coblation equipment promote coblation tonsillectomy as the authors' preferred dissection method.     

Radiofrequency tonsil reduction: safety,morbidity, and efficacy

OBJECTIVES: To evaluate the safety, morbidity, and efficacy of radiofrequency tissue volume reduction of tonsils using two different surgical techniques and to compare these two techniques with each other and with classic tonsillectomy. STUDY DESIGN: A nonrandomized retrospective review of tonsil reductions was made between 2000 and 2002 using in vivo studies associated with tonsil reduction and tonsillectomy performed either in the hospital operating room or in the outpatient treatment area. METHODS: We studied 150 patients and divided them into three main groups based on surgical technique. Group A consisted of 50 consecutive patients who underwent tonsil "ablation," Group B contained another 50 consecutive individuals who received tonsil "coblation," and Group C consisted of 50 patients who underwent classic tonsillectomy (cold dissection). Each group consisted of two subcategories of children (age range, 1-12 y) and adults (age range, 12-60 y) with chronic tonsillar hypertrophy. Most of the pediatric patients underwent adenoidectomy during the same surgical procedure. Indications for tonsillectomy were those listed by the American Academy of Otolaryngology-Head and Neck Surgery. A retrospective chart review was used to assess procedures, safety, morbidity, and efficacy of tonsil reduction and tonsillectomy. Four specific end points of morbidity were investigated: pain, return to normal diet, return to normal activity, and use of pain medication. Efficacy of tonsillectomy was determined by the clinical observation of the remaining tonsillar tissue and compared with pretreatment photographs of the tonsils. RESULTS: There were no complications in any of the groups. Efficacy was assessed based on the mean tonsil reduction and was found to be 100% for tonsillectomy, 86% for the tonsil coblation technique, but only 53.6% for the ablation technique. Morbidity was minimal in groups A and B and significantly greater in Group C. The number of pain days, narcotic-use days, and days before return to normal diet and activity were greatly reduced in groups A and B when compared with classic tonsillectomy (group C). Pain levels on day 1 were less than 3 (on a scale of 1-10) in groups A and B. The number of pain days and narcotic-use days was less than 4 days in groups A and B. Similarly, most patients returned to solid diet and normal activity by day 4. Pain levels, number of narcotic-use days, and number of days to return to normal diet and activity were significantly higher for classic tonsillectomy. CONCLUSIONS: Tonsil coblation has distinct advantages when compared with tonsil ablation and standard tonsillectomy. Tonsil coblation resulted in greater than 86% elimination of tonsillar tissue in both children and adults. In most patients, pain levels were minimal and limited to the first 48 hours after surgery. Return to normal diet and activity was much earlier in the coblation group versus classic tonsillectomy.     

Postoperative tonsillectomy pain in pediatric patients: electrocautery (hot) vs cold dissection and snare tonsillectomy--a randomized trial

OBJECTIVE: To determine the effect of the method of tonsillectomy on postoperative pain in pediatric patients. DESIGN: Prospective, randomized, single-blind, controlled clinical trial. SETTING: A university pediatric hospital in Aberdeen, Scotland. PATIENTS: A volunteer sample of 54 children, aged 3 to 12 years, with recurrent tonsillitis or symptomatic adenotonsillar hypertrophy. Two patients withdrew consent. INTERVENTIONS: Twenty-six children underwent a nonelectrical (ie, cold) dissection tonsillectomy with cold steel instruments, 5 of whom also had adenoidectomy by curettage. Monopolar diathermy forceps were used for tonsillar bed hemostasis. Twenty-four children had electrocautery (ie, hot) dissection tonsillectomy, 7 of whom underwent adenoidectomy by curettage without a suction coagulator. MAIN OUTCOME MEASURES: Postoperative analgesic consumption, time to regain normal diet and activity levels, and complications. RESULTS: Patients who underwent hot dissection tonsillectomy showed no difference in time to first drink or analgesic use within the first 24 postoperative hours compared with children undergoing cold nonelectrical dissection tonsillectomy. The hot dissection tonsillectomy group took 7.5 (95% confidence interval [CI], 1-14.1) more doses of analgesics than the cold dissection group over the next 12 days (P<.05). The hot dissection tonsillectomy group took 2.5 more days than the cold dissection tonsillectomy group to regain normal diet (P<.05). Thirteen children (54%; 95% CI, 34-74) in the hot dissection tonsillectomy group and 6 (23%; 95% CI, 7-39) in the cold dissection tonsillectomy group sought outpatient care for throat pain, otalgia, poor diet, pyrexia, and/or bleeding (P<.05). Throat pain delayed in onset or of prolonged duration affected 9 children (38%; 95% CI, 19-57) in the hot dissection tonsillectomy group as opposed to 3 children (12%; 95% CI, 0-24) in the cold dissection tonsillectomy group (P<.05). CONCLUSION: Hot dissection tonsillectomy increases morbidity in pediatric patients in the recovery period following hospital discharge.
