[PMID: 37868127 PMCID: PMC10586755 DOI: 10.1002/oto2.83] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/31/2023] [Accepted: 09/03/2023] [Indexed: 10/24/2023] Open
Abstract
Objective The microdebrider is a powered surgical instrument that is widely used in the field of otolaryngology. We aim to identify the type and frequency of device malfunctions, patient complications, and subsequent interventions related to the use of microdebriders. Study Design Cross-sectional analysis. Setting The US Food and Drug Administration (FDA) 2011 to 2021 Manufacturer and User Facility Device Experience (MAUDE) database. Methods The MAUDE database was queried for reports of "microdebrider," with adverse events selected that pertained to usage in head and neck surgeries from January 1, 2011 to December 31, 2021. Results There were 282 adverse events in 267 individual medical device reports (MDR). Although the majority of the reports did not specify the specific operation, endoscopic sinus surgery was the most common reported procedure (89, 33.3%). The most common cause of device malfunction was due to a broken piece (120, 48.2%) followed by overheating of the microdebrider motor (78, 31.3%). Of the reports which specified patient injury, the most commonly reported was "unintentional tissue damage," (10, 32.3%). Conclusion The microdebrider has demonstrated utility within the field of otolaryngology, but is not without risk of malfunction that can cause patient injury. By understanding possible risks of microdebrider usage, including tissue damage, burns, and bleeds caused by device malfunction or operator error, physicians can be better prepared to address complications and educate patients.

Abstract
Many surgical instruments have been introduced and compared for safety and surgical efficiency in tonsillectomy. This study aimed to compare postoperative pain between coblation and conventional monopolar electrocautery tonsillectomy by intrapatient comparison in children. Thirty pediatric patients over six years of age undergoing tonsillectomies were enrolled. Coblation and electrocautery were used to remove both tonsils in one patient; one was removed by coblation and the other by electrocautery. The coblation side was randomly selected, and it was blinded to the patients. Each side’s daily pain scores were collected on the visual analogue scale (VAS) during ten postoperative days. On the day of surgery, 22 (73%) patients identified less pain on the coblation side, while others felt similar pain. The mean pain scores were significantly lower on the coblation side during the postoperative ten days (except for the 6th and 8th) than on the electrocautery side. The duration of severe pain (VAS > 5) was significantly shorter on the coblation side than on the electrocautery side (2.0 versus 3.7 days, respectively; p = 0.042). Coblation tonsillectomy induced less pain than electrocautery in pediatric patients; therefore, surgeons could choose the coblator as a surgical instrument for tonsillectomy to improve the pediatric postoperative quality of life.

Feasibility of Powered Intracapsular Tonsillectomy in Pediatric Patients with Tonsil Problem, Including Recurrent Tonsillitis: A Single Surgeon's Experience. ORL J Otorhinolaryngol Relat Spec 2020; 82:335-342. [PMID: 33075791 DOI: 10.1159/000509479] [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: 01/20/2020] [Accepted: 06/15/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Powered intracapsular tonsillectomy (PIT) is a technique that protects the tonsillar capsule by using a microdebrider, resulting in faster wound-healing and reduced suffering. Many studies have found PIT to be effective, particularly in pediatric patients with obstructive sleep apnea (OSA). However, previous studies have not included patients with a history of recurrent tonsillitis. OBJECTIVE The aim of this study was to determine the efficacy of PIT in pediatric patients even with a history of recurrent tonsillitis, and therefore, we want to expand the indication for PIT and reveal its safety. METHODS A total of 886 pediatric patients underwent PIT between February 2013 and March 2016. All patients rated their postoperative pain using a visual analog scale (VAS) and completed the Korean obstructive sleep apnea (KOSA)-18 questionnaire for assessment of their quality of life (QOL). There were 539 males and 347 females. Their mean age was 6.2 years (range 2-14 years). The majority (77.7%) underwent the operation for OSA, and the rest (22.3%) had a history of recurrent tonsillitis. To compare the efficacy of PIT with traditional tonsillectomy, we selected 191 patients who underwent extracapsular tonsillectomy (ECT), a conventional technique, during the same time period. The median follow-up period was 16.7 months. During the follow-up period, instances of delayed bleeding and recurrent pharyngitis were monitored. RESULTS In comparison to the patients who underwent ECT, the PIT group showed significantly fewer cases of postoperative bleeding (p = 0.027). Thirteen patients in the PIT group (1.5%) visited the hospital during the follow-up period for pharyngitis, while 8 in the ECT group (4.2%) visited for pharyngitis. The mean postoperative pain score, as assessed by a VAS, was 4.6 ± 3.2, and pain improved within an average of 2.9 days after surgery in the PIT group. The mean KOSA-18 score for the QOL of the patients was 65.9 preoperatively and 35.6 postoperatively in the PIT group. CONCLUSIONS Pediatric tonsillectomy using PIT is valid for reducing postoperative pain and improving the QOL of OSA patients. PIT is also effective and safe for patients with a history of recurrent tonsillitis.

Abstract
BACKGROUND Recent evidence has challenged the practice of tonsillectomy in children with sleep-disordered breathing. Tonsillotomy (subtotal/partial/intracapsular tonsillectomy) has been proposed as an alternative with equivalent effectiveness and decreased post-operative morbidity, thus improving cost-effectiveness. OBJECTIVE To systematically review the literature comparing clinical efficacy, post-operative morbidity, and cost-effectiveness of tonsillotomy and tonsillectomy in paediatric (<16yo) patients with sleep-disordered breathing. DATA SOURCES A systematic search of MEDLINE, EMBASE, and CENTRAL (1984-July 2014) was conducted. Papers in English directly comparing post-operative outcomes in tonsillectomy and tonsillotomy in children undergoing surgery for sleep-disordered breathing were included. REVIEW METHODS Two authors independently assessed abstracts for relevance, with disagreements resolved by a third author. Selected studies were independently assessed regarding inclusion and exclusion criteria. RESULTS Thirty-two studies satisfied inclusion and exclusion criteria (19 randomised, 13 non-randomised). Patient satisfaction, quality-of-life, and polysomnographic improvement post-surgery did not vary between tonsillotomy and tonsillectomy. Tonsillotomy reduced the odds of a secondary haemorrhage by 79% (OR 0.21, 95% CI 0.17-0.27, p < 0.01), decreased post-operative pain and reduced return to normal oral intake by 2.8 days (95% CI 1.08-4.52, p < 0.01). The odds of readmission were decreased by 62% (OR 0.38, 95% CI 0.23-0.60, p < 0.01). Tonsillotomy had a slightly higher rate of symptom recurrence (4.51%) than tonsillectomy (2.55%), the long-term impact of which was unclear. CONCLUSION Current evidence supports tonsillotomy in children with obstructive surgical indications. It is likely to reduce post-operative haemorrhage, pain, and facilitate a faster return to normal diet and activity. Healthcare burden is decreased due to fewer post-operative complications and reduced need for medical re-contact. More research is necessary to assess the risk of recurrence, and further classification of secondary haemorrhage severity is required to fully clarify the clinical benefit of tonsillotomy.

Abstract
Tonsillectomy is a major surgical procedure in terms of volume in the general otolaryngological practice. It is a 3000-year-old surgical operation, referred in Hindu medicine. There has been a conceptual change in the indications and surgical technique in the last 40 years. A comparative study between the various methods of tonsillectomy was done. The study was carried out in the single institutional set up by the same surgeon but using different techniques. The study aimed at comparing the intra-operative factors (blood loss, time taken for surgery), postoperative results (pain, bleeding, dehydration, time taken for complete healing), and other complications like vomiting and hospitalization time between different groups of surgical methods. This study was done in 2500 patients undergoing tonsillectomy with or without adenoid removal in a period of 35 years (1979-2013). The majority of the patients (approximately 41%) in the first half of this period underwent cold steel tonsillectomy whereas 39% underwent microdebrider assisted tonsillectomy. Microdebrider assisted tonsil surgery was done as day care procedure in 90%. In 21% of the patients, other methods viz coblation, radio frequency and laser were used. Microdebrider intracapsular tonsillectomy is associated with lower mortality and morbidity as compared to cold steel, coblation, electrodissection, laser and radio frequency.

Abstract
Objective A retrospective study to compare surgical parameters and postoperative pain in patients undergoing coblation tonsillectomy with or without microscopic guidance. Methods Data regarding duration of surgery and hospital stay, intraoperative blood loss, incidence of haemorrhage and postoperative pain scores were retrieved from the medical records of adult patients undergoing coblation tonsillectomy under direct vision or with microscopic guidance. Results The incidence of secondary haemorrhage (>24 h postoperatively) was significantly lower and the duration of hospital stay was significantly shorter in the microscope group (n = 92) than the direct vision group (n = 76). Pain scores both at rest and while swallowing reached ≤3 (no significant impact on quality-of-life) significantly faster in the microscope group than the direct vision group. Conclusions Microscope-assisted coblation tonsillectomy decreases the duration of hospital stay and the incidence of postoperative secondary haemorrhage, and results in an early improvement in postoperative pain scores.

Abstract
Surgery of the tonsils is still one of the most frequent procedures during childhood. Due to a series of fatal outcomes after hemorrhage in children in Austria in 2006, the standards and indications for tonsillectomy have slowly changed in Germany. However, no national guidelines exist and the frequency of tonsil surgery varies across the country. In some districts eight times more children were tonsillectomized than in others. A tonsillectomy in children under six years should only be done if the child suffers from recurrent acute bacterially tonsillitis. In all other cases (i.e. hyperplasia of the tonsils) the low risk partial tonsillectomy should be the first line therapy. Postoperative pain and the risk of hemorrhage are much lower in partial tonsillectomy (=tonsillotomy). No matter whether the tonsillotomy is done by laser, radiofrequency, shaver, coblation, bipolar scissor or Colorado needle, as long as the crypts are kept open and some tonsil tissue is left behind. Total extracapsular tonsillectomy is still indicated in severely affected children with recurrent infections of the tonsils, allergy to antibiotics, PFAPA syndrome (periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis) and peritonsillar abscess. With regard to the frequency and seriousness of the recurrent tonsillitis the indication for tonsillectomy in children is justified if 7 or more well-documented, clinically important, adequately treated episodes of throat infection occur in the preceding year, or 5 or more of such episodes occur in each of the 2 preceding years (according to the paradise criteria). Diagnosis of acute tonsillitis is clinical, but sometimes it is hard to distinguish viral from bacterial infections. Rapid antigen testing has a very low sensitivity in the diagnosis of bacterial tonsillitis and swabs are highly sensitive but take a long time. In all microbiological tests the treating physician has to keep in mind, that most of the bacterials, viruses and fungi belong to the healthy flora and do no harm. Ten percent of healthy children even bear strepptococcus pyogenes all the time in the tonsils with no clinical signs. In these children decolonization is not necessary. Therefore, microbiological screening tests in children without symptoms are senseless and do not justify an antibiotic treatment (which is sometimes postulated by the kindergartens). The acute tonsillitis should be treated with steroids (e.g. dexamethasone), NSAIDs (e.g. ibuprofene) and betalactam antibiotics (e.g. penicillin or cefuroxime). With respect to the symptom reduction and primary healing the short-term late-generation antibiotic therapy (azithromycin, clarithromycin or cephalosporine for three to five days) is comparable to the long-term penicilline therapy. There is no difference in the course of healing, recurrence or microbiological resistance between the short-term penicilline therapy and the standard ten days therapy. On the other hand, only the ten days antibiotic therapy has proven to be effective in the prevention of rheumatic fever and glomerulonephritic diseases. The incidence of rheumatic heart disease is currently 0.5 per 100,000 children of school age. The main morbidity after tonsillectomy is pain and the late haemorrhage. Posttonsillectomy bleeding can occur till the whole wound is completely healed, which is normally after three weeks. Life-threatening haemorrhages occur often after smaller bleedings, which can spontaneously cease. That is why every haemorrhage, even the smallest, has to be treated properly and in ward. Patients and parents have to be informed about the correct behaviour in case of haemorrhage with a written consent before the surgery. The handout should contain important addresses, phone numbers and contact persons. Almost all cases of fatal outcome after tonsillectomy were due to false management of haemorrhage. Haemorrhage in small children can be especially life-threatening because of the lower blood volume and the danger of aspiration with asphyxia. A massive haemorrhage is an extreme challenge for every paramedic or emergency doctor because of the difficult airway management. Intubation is only possible with appropriate inflexible suction tubes. All different surgical techniques have the risk of haemorrhage and even the best surgeon will experience a postoperative haemorrhage. The lowest risk of haemorrhage is after cold dissection with ligature or suturing. All "hot" techniques with laser, radiofrequency, coblation, mono- or bipolar forceps have a higher risk of late haemorrhage. Children with a hereditary coagulopathy have a higher risk of haemorrhage. It is possible, that these children were not identified before surgery. Therefore it is recommended by the Society of paediatrics, anaesthesia and ENT, that a standardised questionnaire should be answered by the parents before tonsillectomy and adenoidectomy. This 17-point-checklist questionnaire is more sensitive and easier to perform than a screening with blood tests (e.g. INR and PTT). Unfortunately, a lot of surgeons still screen the children preoperatively by coagulative blood tests, although these tests are inappropriate and incapable of detecting the von Willebrand disease, which is the most frequent coagulopathy in Europe. The preoperative information about the surgery should be done with the child and the parents in a calm and objective atmosphere with a written consent. A copy of the consent with the signature of the surgeon and both custodial parents has to be handed out to the parents.

Abstract
OBJECTIVE Tonsillectomy remains to be an ordinary operative process in otorhinolaryngology. Although there are a plenty of surgical means adopting in otorhinolaryngology, the advantage of one method over another has not been systematically demonstrated. The aim of designing this systematic review is to evaluate the efficiency of electrocautery tonsillectomy (ECT) compared with the microdebrider intracapsular tonsillotomy (MIT). METHODS We retrieved randomized controlled trials (RCTs) from PubMed, EMBASE, Cochrane Library, CBM. Two reviewers extracted the information of included trials independently. The quality of included trials was assessed according to the criteria provided by Cochrane Handbook 5.0.1. RESULTS Four researches were meeting the inclusive criteria which contained 501 participants, 253 in microdebrider tonsillotomy group and 248 in electrocautery tonsillectomy group. Systematic review illustrated that MT group had the recovery to normal activity and diet faster than ECT group [χ(2)=1.02, P<0.00001, 95% CI (-1.74, -1.30)] and [χ(2)=0.01, P<0.0001, 95% CI (-2.56, -0.92)]. There was a statistically significant in blood loss between microdebrider tonsillotomy and electrocautery tonsillectomy, the mean difference of 5.0 ml [P=0.01, 95% CI (3.4, 26.6)]. There was no statistical significance in surgical time. CONCLUSIONS Compared with the electrocautery tonsillectomy, microdebrider tonsillotomy could significantly speed up the time to return to normal activity and normal diet. Two groups were similar in terms of surgical time of tonsillectomy. This conclusion is needed to be further supported by large-scale, high-quality, placebo-controlled, double-blind trials between microdebrider tonsillotomy and other techniques in the surgery time and blood loss of operation.
