All 4 faces pain scales were found to be adequately supported by psychometric data .
When given a choice between faces scales , children preferred the WBFPRS .
Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS .
: For clinical use , we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use .
CONTEXT : Numerous faces scales have been developed for the measurement of  pain intensity in children .
It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity , reliability , feasibility , and preference .
OBJECTIVES : To summarize and systematic ally review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility .
Intracapsular versus subcapsular coblation tonsillectomy
OBJECTIVE : To compare the postoperative recovery of patients who undergo intracapsular to subcapsular Coblation tonsillectomy .  STUDY DESIGN AND SETTING : This was a prospect i ve , r and omized , double-blinded study . A total of 69 children , aged 2 to 16 years , were r and omized to intracapsular ( n = 34 ) or subcapsular ( n = 35 ) tonsillectomy . The Coblation technique was used with both groups . Outcomes measures were assessed on postoperative day 1 or 2 and 5 or 6 . These included child and parental rating of pain with the Wong Faces pain scale , analgesic use , oral intake , and activity level . RESULTS : Intracapsular tonsillectomy patients had similar levels of pain to subcapsular tonsillectomy patients on day 1 or 2 . However , at day 5 or 6 , intracapsular tonsillectomy patients had significantly less pain than the subcapsular tonsillectomy patients . Intracapsular patients ate more and were more active at both time points . CONCLUSION AND SIGNIFICANCE : Children with obstructive sleep apnea who undergo tonsillectomy  demonstrate better postoperative recovery after intracapsular tonsillectomy . The intracapsular versus subcapsular difference may be best appreciated at a delayed time point ( day 5 or 6 ) rather than early ( day 1 or 2 )
