LF impacts the surface skin temperature in the regions of mandibular levator muscles during breastfeeding in the regions of temporal, masseter, and buccinator muscles before and after LF.
Abstract
PURPOSE To analyze surface skin temperature with infrared thermography (IRT) in the regions of the temporal, masseter, and buccinator muscles during breastfeeding before and after LF.
METHODS Non-randomized clinical trial in 40 infants diagnosed with ankyloglossia. The lingual frenulum was assessed with the Neonatal Tongue Screening Test, breastfeeding was assessed with a protocol and pain scale, and the regions of interest were qualitatively and quantitatively assessed with IRT. Two independent evaluators analyzed the data.
RESULTS There were post-LF improvements in the functional-anatomical tongue assessment (p < 0.001), breastfeeding pain scale (p < 0.001), and breastfeeding assessment regarding the mother's general aspect (p < 0.001), breast pain (p = 0.03), and suction (p < 0.001). IRT data after LF showed a qualitative increase in temperature in the regions of the temporal and masseter muscles. There was no difference in the region of the buccinator muscle.
CONCLUSION LF impacts the surface skin temperature in the regions of mandibular levator muscles during breastfeeding.
