Partial intracapsular tonsillectomy in the treatment of pediatric obstructive sleep apnea/hypopnea syndrome: a prospective study with 5-year follow-up

Objective To assess efficacy and safety of tonsil reduction with bipolar forceps electrocautery as treatment of paediatric obstructive sleep apnea/hypopnea syndrome (OSAHS). Study design Prospective interventional study. Methods Two hundred and sixty-three children aged 4–10 years with OSAHS and an apnea hypopnea index (AHI) > 3 were enrolled from March 2013 to January 2016. Pre-operative evaluation included oropharyngeal clinical examination with fiberoptic nasopharyngoscopy, OSA-18 questionnaire and overnight sleep study. All children were treated with adenoidectomy and tonsillotomy with bipolar forceps. OSA-18 questionnaire and overnight sleep study were performed 30 days after surgery. Results Pre-operative average of the OSA-18 questionnaires was of 70.3 (SD = 9.7); 30-day post-operative score was 23.15 (SD = 8.2; p = 0.045). Pre-operative average Apnea Hypopnea Index (AHI) score was 9.41 (SD = 4.1); 30-day post-operative average of AHI score was of 1.75 (SD = 0.8; p = 0.012). Oxygen Desaturation Index (ODI) rate changed from 7.39 (SD = 4) to 1.34 (30-day post-operative) (SD = 4.7; p = 0.085). NADIR rate changed from 79% (SD = 6.32) to 90% (30-day post-operative) (SD = 5.18; p = 0.00012). Peri- and post-operative complications in our sample were mainly pain (average 75 doses of paracetamol), while bleeding did not occur (0%). All patients received a follow-up examination 5 years after surgery to evaluate tonsil size; at this time-point, a reduction in tonsil size from 3.6 (3–4; SD = 4.2) to 1.3 (1–2; SD = 5.5) was found, while tonsil regrowth was observed in five children (2%). Conclusion This study showed that partial tonsillotomy with bipolar forceps electrocautery associated to adenoidectomy is an effective technique in treating OSAHS symptoms in children and ensures less complications in terms of hemorrhage, postoperative pain and infections compared to traditional adenotonsillectomy. The very low tonsillar regrowth rate reported in this study may support the routine use of this technique.

400 A Comparative Study of Intracapsular & Extracapsular Coblation Paediatric Tonsillectomy in A Tertiary Centre

Background Intracapsular tonsillectomy has emerged as a novel alternative to traditional tonsillectomy where the tonsillar capsule is left intact with a small amount of overlying tonsillar tissue. There is growing evidence to suggest that intracapsular tonsillectomy is associated with reduced post-operative pain, haemorrhage and readmission rates. The aim of this study was to assess the reported benefits of intracapsular tonsillectomy within the ENT department at a tertiary paediatric hospital. Method Retrospective analysis comparing two cohorts of 72 consecutive paediatric patients undergoing coblation intracapsular and extracapsular tonsillectomy between March-2019 and November-2020. Patient age at procedure, removal of adenoids, indication, surgeon grade, and discharge time were recorded. Post-tonsillectomy bleeding and 30-day readmission rates were used as the main outcome measures. Results The median age in both groups was 5 years. The intracapsular cohort demonstrated a lower 30-day readmission rate (8.3% vs. 15.3%), lower primary (<24 hours) post-op bleed rate (0% vs. 2.78%) and lower secondary (>24hours) post-op bleed rate (4.2% vs. 12.5%) when compared to the extracapsular cohort. Eight cases were conducted as day cases in total, all Intracapsular, with none of these patients requiring readmission within 30 days. Discussion Coblation Intracapsular tonsillectomy is an effective and low-risk alternative to extracapsular techniques. It is hoped with the reduced associated risks and morbidity associated with the procedure, the department can move towards day case tonsillectomy procedures resulting in a reduction in overall healthcare costs and improved patient experience.

Predictive Pediatric Characteristics for Revision Tonsillectomy After Intracapsular Tonsillectomy

Objectives There is little research on the rate and risk factors for revision tonsillectomy after primary intracapsular tonsillectomy. Our study aimed to determine the revision rate following intracapsular tonsillectomy, identify patient characteristics that may increase the probability of revision surgery, and report the tonsillar hemorrhage rate after revision. Study Design Level III, retrospective case-control study. Setting A tertiary care pediatric center (Alfred I. duPont Hospital for Children, Wilmington, Delaware). Methods A case-control study of pediatric patients who underwent intracapsular tonsillectomy between January 1, 2004, and December 31, 2018, was performed. Patients aged 2 to 20 years were analyzed and compared with matched controls who underwent intracapsular tonsillectomy within 7 days of the same surgeon’s case. In total, 169 revision procedures were included with 169 matched controls. Results A 1.39% revision rate was observed among a total of 12,145 intracapsular tonsillectomies. Among the 169 patients who underwent a revision procedure, the mean time between cases was 3.5 years. Tonsillitis was the most common diagnosis prompting revision tonsillectomy. Four (2.4%) patients underwent operative control of a postoperative tonsillar hemorrhage after revision surgery. Younger patients ( P < .001) and patients with a history of gastroesophageal reflux disease ( P = .006) were more likely to undergo revision tonsillectomy. Conclusion Patients below age 4 years and patients with gastroesophageal reflux disease may be at increased risk of undergoing revision tonsillectomy after primary intracapsular tonsillectomy. These factors should be considered when selecting an intracapsular technique for primary tonsillectomy in pediatric patients.

Subtotal intracapsular tonsillectomy may be the first choice for tonsillectomy in children

Objective To investigate the effect and prognosis of subtotal intracapsular tonsillectomy. Methods All children (n=162) with tonsillar hypertrophy and chronic tonsillitis were randomly divided into two groups: tonsillectomy (n=75) and subtotal intracapsular tonsillectomy (n=87). Tonsillectomy: the tonsillar tissue was completely removed along with the tonsillar capsule. Subtotal intracapsular tonsillectomy: 80% to 90% of the tonsils and the complete epithelium of the tonsillar crypts were removed without damaging the tonsillar capsule. The Face, Legs, Activity, Cry, and Consolability (FLACC) and parents’ postoperative pain measure (PPPM) scales were used to evaluate postoperative pain, and the obstructive sleep apnea (OSA)-18 questionnaire was used to assess the children’s postoperative quality of life. The patients were followed-up for 2 years. Results 1. The FLACC and PPPM scales indicated that the children’s postoperative pain after subtotal intracapsular tonsillectomy was significantly less than that of children undergoing tonsillectomy. 2. The OSA-18 scale scores indicated that subtotal intracapsular tonsillectomy significantly improved the children’s quality of life. 3. Two years after subtotal intracapsular tonsillectomy, no patients required reoperation. Conclusion Subtotal intracapsular tonsillectomy may be the first choice for tonsillar hypertrophy and chronic tonsillitis patients.

Intracapsular coblation tonsillotomy versus extracapsular coblation tonsillectomy

Background Recently, coblation technique is used in many neck surgeries; there are few studies dealing with coblation in the field of tonsillectomy either intracapsular or extracapsular tonsillectomy. The aim of this study is to evaluate the efficacy of using coblation in extracapsular tonsillectomy (preserving the capsule) over using it in intracapsular tonsillectomy (total). Results There is statistically difference between results of extracapsular tonsillectomy and intracapsular tonsillectomy as regards postoperative pain according VAS scale (4.36 ± 2.413 vs 3.6 ± 2.041 with p value 0.0001). Also postoperative dietary intake and daily activity all are significantly different in extracapsular tonsillectomy and these differences were recorded after the fifth day. Conclusion Extracapsular coblation tonsillectomy has less morbidity than intracapsular coblation tonsillectomy.
