An anatomically sound surgical simulation model for myringotomy and tympanostomy tube insertion.

OBJECTIVE: Myringotomy and tympanostomy tube insertion (MT) is a common surgical procedure. Although surgical simulation has proven to be an effective training tool, an anatomically sound simulation model for MT is lacking. We developed such a model and assessed its impact on the operating room performance of senior medical students. STUDY DESIGN: Prospective randomized trial. METHODS: A randomized single-blind controlled study of simulation training with the MT model versus no simulation training. Each participant was randomized to either the simulation model group or control group, after performing an initial MT procedure. Within two weeks of the first procedure, the students performed a second MT. All procedures were performed on real patients and rated with a Global Rating Scale by two attending otolaryngologists. Time to complete the MT was also recorded. RESULTS: Twenty-four senior medical students were enrolled. Control and intervention groups did not differ at baseline on their Global Rating Scale score or time to complete the MT procedure. Following simulation training, the study group received significantly higher scores (P=.005) and performed the MT procedure in significantly less time (P=.034). The control group did not improve their performance scores (P>.05) or the time to complete the procedure (P>.05). CONCLUSION: Our surgical simulation model shows promise for being a valuable teaching tool for MT for senior medical students. Such anatomically appropriate physical simulators may benefit teaching of junior trainees.

The effect of tongue-tie division on breastfeeding and speech articulation: a systematic review.

OBJECTIVE: To systematically review the outcomes of tongue-tie division procedures in patients with ankyloglossia with the goal of (1) deriving clinically oriented insights into the effect of tongue-tie division procedures and (2) identifying needs in knowledge to stimulate further research. DATA SOURCES: Medline, EMBASE, and Cochrane databases were searched without any limitations, for studies published between 1966 and June 2012. REVIEW METHODS: Studies were included (level 4 evidence or above) if subjects of any age had ankyloglossia and underwent tongue-tie release. Outcome measures of interest were any subjective or objective measures of breastfeeding and speech outcomes, or reports of adverse events. RESULTS: In all, 378 abstracts were generated from the literature searches; 20 studies met the criteria for data extraction and analysis. Of those, 15 studies were observational and 5 were randomized controlled trials. Tongue-tie division provided objective improvements in the following: LATCH scores (3 studies); SF-MPQ index (2 studies); IBFAT (1 study); milk production and feeding characteristics (3 studies); and infant weight gain (1 study). Subjective improvements were also noted in maternal perception of breastfeeding (14 studies) and maternal pain scores (4 studies). No definitive improvements in speech function were reported. The only significant adverse events were recurrent tongue-ties that required repeat procedures. CONCLUSION: Ankyloglossia is a well-tolerated procedure that provides objective and subjective benefits in breastfeeding; however, there was a limited number of studies available with quality evidence. There are no significant data to suggest a causative association between ankyloglossia and speech articulation problems. Aspects of ankyloglossia that would benefit from further research are described, and recommendations for tongue-tie release candidacy criteria are provided.
