TA represented 3050% of all pediatric surgeries in the 1930s,The advent of antibiotics in the 1950s resulted in a dramatic decrease in the overall number of tonsillectomies. In the USA, the frequency dropped from 1,400,000 TAs per year in 1959 to 500,000 in 1979, In the UK, 200,000 tonsillectomies per year in 1930 to 50,000 at the beginning of the 21st century,Indications of Pediatric Tonsi,6,The series published during the last 30 years show a clear shift in the indications of tonsillectomy. Sleep-disordered breathing is now the main reason for TA in children. All studies published in the last few years show this trend, which is even more obvious in children under 3 years of age, where OSAS reaches 90100% of indications. In older children, infections are more frequent indications for TA,The series published during th,7,Tonsillectomy: A Simple Surgical Procedure ?,Austrian events,：,The death of 5 children in Austria below the age of 6 years due to posttonsillectomy haemorrhage in 2006 and 2007 showed how quickly medical procedures can be discussed and debated by the media and politicians,As a consequence, the Austrian Pediatric and ENT Societies had to revise and tighten the guidelines,for adenotonsillectomy,Tonsillectomy: A Simple Surgic,8,The main aim is to restrict tonsillectomies to cases where the complete tonsil has to be dissected. The criteria,for tonsillectomy are formulated vigorously: at least 7 tonsil infections in 1 year or 5 tonsil infections in each of 2 consecutive years have to be documented prior to the removal of the tonsils. For children younger than 6 years of age with tonsil hypertrophy, tonsillotomy rather,than tonsillectomy is recommended. Furthermore, an overall hospital stay of 23 nights for inpatient surgery is suggested,The main aim is to restrict to,9,During the evaluation period from October 1, 2009, to June 30, 2010, all consecutive tonsil and adenoid surgeries in Austria (n = 9,405 patients) and their risk factors were evaluated.,During the evaluation period f,10,Bleeding episodes of grades A to B are named minor bleedings, grades C to E are severe bleedings,Bleeding episodes of grades A,11,小儿腺样体扁桃体切除术培训ppt课件,12,Postoperative haemorrhage, defined as every bleeding episode after extubation, was reported in 12.3% after tonsillectomy; one fourth of whom experienced multiple bleedings.,After tonsillotomy only 2.2% patients reported a postoperative bleeding episode,Postoperative haemorrhage, def,13,Figure 2 indicates an increasing risk of haemorrhage with rising age for tonsillectomy, the distribution of minor versus severe bleeding episodes is equal,Figure 2 indicates an increasi,14,Figure 3 shows a low rate of bleeding episodes after tonsillotomy (2.2%) with very few cases requiring surgical treatment under general anaesthesia (0.7%).,Figure 3 shows a low rate of b,15,小儿腺样体扁桃体切除术培训ppt课件,16,扁桃体切除术与扁桃体部分切除术，术后出血存在差异,应用奥地利共识后，奥地利扁桃体切除术术后出血，需回手术处理的比率还是在文献所报告的上限,少量出血是严重出血的预兆,统一术后出血观察标准的意义,奥地利事件后，对6岁以下小儿，推荐扁桃体部分切除术（Intracapsular Tonsillectomy、tonsillotomy）,扁桃体切除术与扁桃体部分切除术，术后出血存在差异,17,术后第一天需严密观察，即使是小量出血,The events in Austria showed that lethal posttonsillectomy haemorrhage is a reality we are faced with and that strict monitoring of indications and complications might decrease the rate of lethal events in the future. Moreover, parents became alerted to the potential risks of tonsillectomies through the media.,Based on our experience and growing medicalization, we encourage colleagues in other countries to think about the lack of standardized and nationwide monitoring of tonsil surgeries and their complications in order to improve the safety of such surgeries.,术后第一天需严密观察，即使是小量出血,18,Tonsillectomy,与,Intracapsular Tonsillectomy,1930年Fowler 提出removing “the tonsil, the whole tonsil, and nothing but the tonsil,” 措施是在咽肌与扁桃体被囊间anatomical dissection，当时，扁桃体切除术针对的是慢性扁桃体炎,囊内扁桃体切除术，留下被囊，意味留下部分扁桃体组织，扁桃体再生长率增加，因此，囊内扁桃体切除术是为慢性扁桃体切除的禁忌症，但是对OSAS，是安全有效的方法,Tonsillectomy与Intracapsular To,19,Coblation,离子射频低温消融,Coblation creates significantly less epithelial destruction and collateral tissue damage compared with conventional monopolar electrocautery. Additionally, Coblation technology offers superior versatility because it is effective for performing a wide range of surgeries, including,subcapsular tonsillectomy,( fig. 1 ),intracapsular tonsillectomy,( fig. 2 ) and adenoidectomy, all with the same device,Coblation离子射频低温消融Coblation cre,20,Fig. 1.,Subcapsular tonsillectomy, intraoperative view.,Fig. 1.
