Hemorrhage following Coblation Tonsillectomy

A comparison of coblation and modified monopolar tonsillectomy in adults

OBJECTIVE

To compare the intraoperative records and postoperative clinical outcomes of adults who underwent coblation and modified monopolar tonsillectomy tonsillectomies.

MATERIALS AND METHODS

Adult patients with tonsillectomy were randomly divided into the coblation and modified monopolar tonsillectomy groups. The estimated blood loss, postoperative pain score, operation time, post-tonsillectomy hemorrhage (PTH), and cost of disposable equipment were compared.

RESULTS

Pain intensity in the coblation and monopolar groups was similar on postoperative days 3 and 7. However, the mean maximum pain score in the monopolar group was significantly higher compared to the coblation group on postoperative days 1 (P < 0.01) and 2 (P < 0.05).Secondary PTH occurred in 7.1% (23/326) of patients in the coblation group and 2.8% (9/327) of patients in the monopolar group (P < 0.05).

CONCLUSION

Although pain was significantly increased on postoperative days 1 and 2 in the modified monopolar tonsillectomy group, the operation time, secondary PTH, and medical costs were significantly decreased compared to the coblation technique group.

Multicentre clinical study of haemorrhage after coblation tonsillectomy in children: a prospective study protocol

INTRODUCTION

Post-tonsillectomy haemorrhage (PTH) is the most common and significant life-threatening complication following tonsillectomy, especially in children. Coblation tonsillectomy (CTE) at low temperature is extensively used in China and has gradually replaced conventional tonsil dissection. However, risk of late PTH has been shown to increase with the use of hot instruments. The aim of this study is to detect post-CTE haemorrhage (PCTH) rates and analyse risk factors of PCTH in China, through a nationwide multicentre prospective study.

METHODS AND ANALYSIS

This investigator-initiated, prospective, multicentre clinical trial will involve children with tonsil disease who will undergo CTE from 22 research centres in different cities in China. All operations will be performed using the same technique of extracapsular tonsillectomy. Data will be collected for all patients enrolled in this study through a preoperative visit, intraoperative data and a postoperative visit. The measurement data conforming to a normal distribution will be expressed by means±SDs, and a Student's t-test will be used for comparison. The comparison among groups of counting data will be expressed by percentage or rate, and a χ² test will be used for comparison. Non-conditional logistic regression analysis will be used to analyse the preoperative, intraoperative and postoperative risk factors for haemorrhage rate after CTE. P<0.05 will be considered statistically significant.

ETHICS AND DISSEMINATION

This study protocol was approved by the Ethics Committee of Shanghai Children's Hospital/Shanghai Jiao Tong University (reference number 2021R096-E01). All patients will provide written informed consent. Results of this study are to be published in respected, peer-reviewed journals and findings presented at scientific conferences in the field of paediatric otorhinolaryngology.

A single center retrospective comparison of post-tonsillectomy hemorrhage between BiZact and Coblator

INTRODUCTION

Over 550,000 tonsillectomies are performed every year. While post-tonsillectomy hemorrhage (PTH) has been studied in the coblator, bovie, and cold steel technique, there is a dearth of studies examining the post-tonsillectomy outcome using BiZact. This study examines the rate of BiZact PTH requiring control of hemorrhage in the OR and assess resident comfort using the device.

METHODS

Retrospective chart review for all tonsillectomies performed between January 2018 and December 2020 were performed. Rates of PTH were analyzed. In addition, a 7-question BiZact resident experience survey was administered to 25 otolaryngology residents.

RESULTS

1384 patients were included in this study; 444 (32%) Bizact and 940 (68%) Coblation. 11 (2.48%) BiZact patients had PTH requiring OR for control of hemorrhage, compared to 44 (4.68%) Coblation patients. There were no patient deaths because of PTH. The mean age of patients with PTH was 7.44 (SD 4.07) years old. 22 (88%) residents responded to the survey. 17 (77.27%) felt more confident with Coblator while performing tonsillectomy most commonly reported for ease of use, followed by BiZact 4 (18.18%), most commonly reported for improved surgical plane.

CONCLUSION

BiZact is a safe and effective addition. At our institution, the rate of secondary PTH requiring OR intervention for BiZact is comparable to the national average for other tonsillectomy devices. The rate of BiZact PTH requiring OR intervention in our experience was nearly half of those done with Coblator. Overall residents at SCHC preferred Coblator over BiZact mainly attributed to Coblator's versatility and ability to control intraoperative tonsil bleeding without additional instruments despite BiZact's shorter operative time.

Predictors of Occurrence and Timing of Post-Tonsillectomy Hemorrhage: A Case-Control Study

OBJECTIVE

To describe cases and timing of pediatric post-tonsillectomy hemorrhage (PTH), to evaluate predictors of PTH, and to determine the optimal amount of postoperative care unit (PACU) monitoring time.

STUDY DESIGN

Using the Pediatric Health Information System (PHIS) database and electronic medical records, a matched case-control study from 2005 to 2015 was performed.

SETTING

A single, tertiary-care institution.

SUBJECTS AND METHODS

Each case of PTH was matched with 1 to 4 controls for the following factors: age, sex, surgeon, and time of year. A total of 124 cases of PTH and 479 tonsillectomy controls were included. The rate and timing of postoperative bleeding were assessed, and matched pair analysis was performed using conditional logistic regression.

RESULTS

Our institutional PTH rate of 1.9% (130 of 6949) included 124 patients; 15% (19) were primary (≤24 hours), with 50% (9) occurring within 5 hours. Twenty-one percent (4 of 19) of primary PTH patients received operative intervention. Eighty-five percent (105 of 124) of all cases were secondary PTH, and 47% (49) of those patients received operative intervention. Cold steel (OR 1.9, 95% CI 1.1-3.3) and Coblation (OR 1.9, 95% CI 1.2-3.1) techniques and tonsillectomy alone (OR 3.7, 95% CI 1.9-7.2) increased odds of PTH. Patients who developed PTH had 4 times the odds of having a preceding postoperative respiratory event than controls (OR 4.0, 95% CI 1.6-10.0).

CONCLUSION

We conducted a rigorous case-control study for PTH, finding that PTH was associated with use of cold steel and Coblation techniques and with tonsillectomy alone. Patients with a postoperative respiratory event may be more likely to develop a PTH and should be counseled accordingly. A PACU monitoring time of 4 hours is sufficient for outpatient tonsillectomy.

Cauterization tonsillectomy as compared to traditional tonsillectomy technique

Background:

Tonsillectomy is one of the most frequently applied and oldest surgical procedures in otorhinolaryngology. Various surgical techniques are used to perform this operation including traditional and cauterization techniques.

Objectives:

To assess morbidity and efficacy and compare objectively the techniques in tonsillectomy, i.e., traditional technique and cauterization technique. This study compares the traditional and cauterization tonsillectomy techniques in view of their advantages and complications.

Methods:

This is a retrospective study and comparative study, conducted during the period from January 2017 to March 2018 from the patients attending to Alnamas General Hospital, Aseer Region, Saudi Arabia. The questionnaire was designed to compare the traditional and cauterization tonsillectomy. Fifty patients underwent traditional technique and fifty patients underwent cauterization method. The data analyzed using SPSS V.16.0 (SPSS Inc; Chicago, IL, USA).

Results:

A total of 100 patients, 62 males and 38 females, aged 8 to 16 years were included in the study. A total of 100 patients were enrolled in the study. Traditional and cauterization tonsillectomy were performed. 50 (27 male and 23 female) patients, whose ages ranged from 9 to 16 years old underwent the traditional tonsillectomy, 50 (35 male and 15 female) patients whose ages ranged from 8 to 16 years underwent cauterization. The two groups were similar for demographic parameters. The difference between mean operative times of the two methods was statistically significant. Postoperative bleeding is significantly higher in the traditional technique compared to cauterization method. Postoperative pain is significantly less in cauterization method. Only a few patients experienced fever, bleeding, and other complications related to anesthesia. The bleeding severity is significantly lower in the cauterization technique. Postoperative pain was less in cauterization technique on day 1 and day 5. Postoperative pain was from mild to severe.

Conclusion:

This study revealed significantly less postoperative complications in traditional tonsillectomy in comparison with the cauterization method. Healing time was significantly faster in cauterization technique than in traditional method.

Coblation tonsillectomy versus cold steel dissection tonsillectomy: a morphological study

Objective

To compare the extent of tissue damage produced by conventional cold steel and coblation tonsillectomy.

Methods

Twenty patients underwent conventional and 18 underwent coblation tonsillectomy. The removed tonsils were histopathologically evaluated.

Results

Analgesic use was lower in the coblation group during the early post-operative period. Histological investigation of tonsils removed by the conventional method showed intensive haemorrhage and hyperaemia in the tonsillar capsules, which was not seen in the coblation group. Furthermore, in the coblation group, there was less mast cell degranulation (p = 0.0081) and a smaller amount of skeletal muscle tissue (p = 0.0043) in the tonsillar capsules, indicating less tissue damage.

Conclusion

Compared to the cold steel technique, coblation tonsillectomy is superior in terms of less early post-operative pain and less damage to surrounding tissues. Significantly lower mast cell degranulation in coblation tonsillectomy may contribute to the reduction of post-operative pain.

The debate continues: a prospective, randomised, single-blind study comparing Coblation and bipolar tonsillectomy techniques

OBJECTIVES

Tonsillectomy is a common procedure with significant post-operative pain. This study was designed to compare post-operative pain, returns to a normal diet and normal activity, and duration of regular analgesic use in Coblation and bipolar tonsillectomy patients.

METHODS

A total of 137 patients, aged 2-50 years, presenting to a single institution for tonsillectomy or adenotonsillectomy were recruited. Pain level, diet, analgesic use, return to normal activity and haemorrhage data were collected.

RESULTS

Coblation tonsillectomy was associated with significantly less pain than bipolar tonsillectomy on post-operative days 1 (p = 0.005), 2 (p = 0.006) and 3 (p = 0.010). Mean pain scores were also significantly lower in the Coblation group (p = 0.039). Coblation patients had a significantly faster return to normal activity than bipolar tonsillectomy patients (p < 0.001).

CONCLUSION

Coblation tonsillectomy is a less painful technique compared to bipolar tonsillectomy in the immediate post-operative period and in the overall post-operative period. This allows a faster return to normal activity and decreased analgesic requirements.

Liability under post-tonsillectomy lethal bleeding of the tonsillar artery: a report of two cases

Post-operative haemorrhage is a frequent complication of tonsillectomy: a primary haemorrhage occurring in the first hours is rapidly dealt with by the surgical team. A secondary haemorrhage, which commonly occurs once the child has returned home, can be fatal if it is not dealt with quickly. We present two cases of a lethal outcome in children following a secondary post-tonsillectomy haemorrhage, for which the parents filed legal proceedings. Medical liability can be exercised during all stages of health care. Performing an autopsy associated with histological analyses is found to be indispensable for the identification of the causes of bleeding, as well as its mechanism.

High incidence of post-tonsillectomy secondary haemorrhage following coblation tonsillectomy

To examine the incidence of haemorrhage following tonsillectomy, to explore the usefulness of antibiotic in preventing postoperative haemorrhage and to examine if the haemorrhage depended on the level of expertise of the surgeon. A retrospective review analysing tonsillectomy method, the rate secondary haemorrhage, the grade of operating surgeon. A χ(2) analysis was used to determine the statistical difference between the haemorrhage rates of different tonsillectomy methods. One thousand three hundred and thirty-six tonsillectomies were performed during this period by four different methods: 615 by cold steel dissection, 582 by Coblation, 32 by bipolar dissection and 107 by Helica thermal coagulation. 621 tonsillectomies were performed by Consultant grade and middle grades performed 693 operations. 124 patients (9.3 %) were readmitted with haemorrhage. The secondary haemorrhage requiring surgery for controlling bleeding for cold steel dissection method was 1.5 % compared to 6.7 % for coblation method (P < 0.01 %), 6.3 % for bipolar dissection and 1.9 % for Helica thermal coagulation method. Overall consultants had a post tonsillectomy haemorrhage rate of 5.5 % and middle grades had a rate of 3.7 %. 86.5 % of the patients were already on routine prophylactic oral antibiotics at the time of presentation with haemorrhage needing surgical arrest and 13.5 % were not on antibiotics (P < 0.05 %). There was statistically significant difference in secondary haemorrhage rate between coblation and cold steel dissection methods. Coblation tonsillectomies had an increased need for operative intervention to control secondary haemorrhage. Routine use of antibiotic and expertise of operating surgeon had no bearing on secondary haemorrhage rate.

Coblation tonsillectomy in children: incidence of bleeding

OBJECTIVES/HYPOTHESIS

To evaluate the intraoperative and postoperative bleeding rate utilizing the Coblation device for total tonsillectomy in children.

STUDY DESIGN

Prospectively designed clinical study.

METHODS

Institutional review board approval was obtained to study patients undergoing Coblation tonsillectomy. Records of all children 1 to 18 years of age undergoing tonsillectomy or adenotonsillectomy from April 2003 to April 2010 were reviewed. All children underwent total tonsillectomy utilizing the Coblation device, and the intraoperative and postoperative bleeding complications were analyzed. The data were also analyzed to determine whether surgeon experience with the technique influenced the bleeding rate.

RESULTS

A total of 1,918 patients were evaluated. Intraoperative blood loss was <5 mL in >90% of the patients, with no patients experiencing >20 mL of blood loss. The postoperative bleeding rate was consistent with the literature (n = 87, 4.5%). Of the patients with bleeding following surgery, five (5.7%) experienced primary bleeding and 82 (94.3%) secondary bleeding. Postoperative bleeding that ceased spontaneously and did not require intervention was present in 56 (2.9%). The number of patients who actually required intervention to control postoperative bleeding was 31 (1.6%). The majority of bleeding occurred by postoperative day 7. There was no statistically significant difference in bleeding rates by age, and there was no evidence found to support a surgeon learning curve for performing Coblation tonsillectomy.

CONCLUSIONS

This study provides further support that Coblation total tonsillectomy in children is a reliable and safe procedure with a relatively low incidence of intraoperative and postoperative bleeding.

Is the systemic inflammatory reaction to surgery responsible for post-operative pain after tonsillectomy, and is it "technique-related"?

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.

Coblation-assisted endonasal endoscopic resection of juvenile nasopharyngeal angiofibroma

Objective:

Juvenile nasopharyngeal angiofibroma may be successfully resected using endoscopic techniques. However, the use of coblation technology for such resection has not been described. This study aimed to document cases of Fisch class I juvenile nasopharyngeal angiofibroma with limited nasopharyngeal and nasal cavity extension, which were completely resected using an endoscopic coblation technique.

Methods:

We retrospectively studied 23 patients with juvenile nasopharyngeal angiofibroma who underwent resection with either traditional endoscopic instruments (n = 12) or coblation (n = 11). Intra-operative blood loss and overall operative time were recorded.

Results:

The mean tumour resection time for coblation and traditional endoscopic instruments was 87 and 136 minutes, respectively (t = 9.962, p < 0.001). Mean intra-operative blood loss was 121 and 420 ml, respectively (t = 28.944, p < 0.001), a significant difference. Both techniques achieved complete tumour resection with minimal damage to adjacent tissues, and no recurrence in any patient.

Conclusion:

Coblation successfully achieves transnasal endoscopic resection of juvenile nasopharyngeal angiofibroma (Fisch class I), with good surgical margins and minimal blood loss.

A randomised controlled trial to compare postoperative pain in children undergoing tonsillectomy using cold steel dissection with bipolar haemostasis versus coblation technique

OBJECTIVE

To measure postoperative pain levels in children undergoing tonsillectomy, by two different techniques, cold steel dissection and coblator dissection. The hypothesis - that coblator dissection may be associated with less postoperative pain.

DESIGN

Prospective, randomised, double blind trial.

SETTING

Single centre, secondary care Children's Hospital.

PARTICIPANTS

Children aged between 4 and 16 years, undergoing tonsillectomy, or adeno-tonsillectomy.

EXCLUSION CRITERIA

children already taking regular analgesia and those who experienced postoperative bleeding. Seventy-nine children were recruited, nine were excluded.

MAIN OUTCOME MEASURES

We compared analgesia requirements during the first 10 days, and also the return to normal eating and drinking. These were assessed, using a validated pain scale. All analgesic administration in hospital and at home was compared. The return to normal eating & drinking patterns, was also compared.

RESULTS

Whilst in the 24 h postoperatively there was no significant difference in the pain scores between the two groups, the coblator group required less potent analgesia. No statistical difference was identified between the two groups following discharge, except on the sixth postoperative day, when the coblator group had lower pain scores. This may represent chance, rather than a clear difference.

CONCLUSION

The findings do not confirm the hypothesis that tonsillectomy undertaken in children, with the coblator device, is associated with lower levels of postoperative pain, but do indicate that less analgesia is required by the coblator patients in the first 12 h postoperatively.

The coblation tonsillectomy learning curve

OBJECTIVE

To establish if there is a learning curve for coblation tonsillectomy.

STUDY DESIGN

Regression analysis of data obtained from surgeons identified from the Australian Tonsillectomy Survey.

SUBJECTS AND METHODS

Thirty otolaryngologists were invited to contribute audit data. Data were stratified into groups of 10 procedures and analysed with regression analysis.

RESULTS

Nineteen (70%) surgeons responded. Complete data were obtained for 1700 cases and return to theatre data on 2062 cases. There was a significant learning curve with respect to both primary (P = 0.050) and secondary (P = 0.028) hemorrhage rates. Mean rates were 0.3% (95% CI 0.1% to 0.7%) and 2.1% (95% CI 1.5% to 2.9%) for primary and secondary bleeds, respectively, with return to theatre in 0.2% (95% CI 0.1% to 0.5%) and 1.3% (95% CI 0.9% to 1.9%), respectively.

CONCLUSION

The introduction of coblation tonsillectomy into Australia was associated with a statistically significant learning curve with respect to both primary and secondary hemorrhage rates.

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.

Coblation tonsillectomy: a prospective, double-blind, randomised, clinical and histopathological comparison with dissection–ligation, monopolar electrocautery and laser tonsillectomies

Introduction:

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.

Surgery for Pediatric Sleep Apnea

Sleep-related breathing disorders (SRBD) in children are caused by a diverse group of anatomic and physiologic pathologies. These disorders share a common clinical presentation as stertor or sonorous breathing, occasionally accompanied by apneic events of variable duration. Successful management depends on accurate identification of the site of obstruction and the severity of obstruction. Intervention, both surgical and nonsurgical, is tailored to the disorder. In children with SRBD, such intervention may alter behavior and cognition, improve sleep and feeding, or even save a life.

Wundheilungsstörung nach Tonsillektomie

Tonsillectomy is one of the most commonly performed surgical procedures in the field of otorhinolaryngology. The first tonsillectomy was done about 600 B.C. [3]. This operation is indicated for patients with recurrent tonsillitis, peritonsillar abscess, hypertrophy or asymmetry of the tonsils. Even though a routine procedure, it has a relatively high risk of complications such as post operative hemorrhage, infection or impaired wound healing. The reported case involves a 20 year old female patient who developed velopharyngeal insufficiency as a result of impaired wound healing after tonsillectomy. The patient was treated conservatively and is free of discomfort after 2 months.

Painless tonsillectomy

PURPOSE OF REVIEW

Even though pediatric tonsillectomy is a well accepted treatment for upper airway obstruction or recurrent tonsillar infection, the painful recovery of this operation is unwelcome. As more studies are published on the beneficial effects of tonsillectomy, the number of tonsillectomies performed is likely to increase. It would behoove any surgeon performing this operation to be aware of the available options for post/perioperative pain control.

RECENT FINDINGS

New techniques used to perform tonsillectomy, innovative adjuvant medical therapy and other tools are reviewed.

SUMMARY

The search for 'the painless tonsillectomy' continues. Finding a technique that works best for each surgeon is paramount to successful tonsillectomy. Patient comfort, surgical time, complications such as bleeding and regrowth of tonsillar tissue, or recurrence of symptoms that lead to the initial operation should all be considered in the surgeon's choice of a particular tonsillectomy technique. Medical therapies such as corticosteroids in the perioperative period are well accepted as a pain adjuvant. Newer adjuvants include the use of pretonsillectomy injection of mixtures that include local anesthetics with opioids and clonidine. The use of nonsteroidal antiinflammatory drugs appears to be helpful for pain, but controversial regarding bleeding. Another successful strategy used to decrease pain perception is distraction.
