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 .
Tonsillectomy or tonsillotomy?--A randomized study comparing postoperative pain and long-term effects.
BACKGROUND tonsillectomy ( TE ) is currently the most common treatment for children with snoring and sleep apnea . Many of these children have not had any severe throat infections . To cure such children from their obstructive problems , without influencing the immunological function of the tonsils , tonsillotomy ( TT ) with CO2-laser was performed in a r and omized study comparing it to regular tonsillectomy , with special attention to postoperative pain and symptom recurrence . METHOD 41 children 3.5 - 8 years-old were included--21 ' TT 's ' and 20 ' TE 's ' . They were all operated under the same anesthesia and followed the same postoperative scheme for analgesia . A visual analogue scale for pain measurements with faces was used for the first 24 h. After that , each day until pain-free , the parents registered the child 's pain on a three grade d scale , what the child was able to eat , and the amount of analgesic drugs used . RESULTS all the children were cured from their breathing obstruction . The mean time used for the surgery was the same and no postoperative bleeding was seen in either group . ' TT children ' were pain-free after 5 days and ' TE children ' after 8 days . Eight to ten days after surgery , the TT-children had gained weight and the TE children lost weight significantly . The TE group used twice as much analgesic drugs as the TT group during the first postoperative week . The TT group was healed with normal-looking , but small tonsils after 8 - 10 days ; the TE group often still showed edema and crusts . At the one-year follow-up 2/21 among the ' TT-children ' snored , but did not require re-surgery . CONCLUSION tonsillotomy is much less painful than TE and children recover more quickly . Results with respect to breathing obstruction are almost the same for both methods at 1-year follow-up
