A technique to reconstruct the hair-bearing upper lip by means of a hair-loaded nasal vestibular flap is described. This flap is elevated from the nasal vestibular area, and does not result in nasal deformity. This flap is especially suitable to reconstruct the medial portion of the hair-bearing upper lip in adult males.
Small tufts of chest hair were epilated at different rates and the roots classified as to growth phase, presence or absence of root sheaths and whether the shafts were fractured. With respect to anagen roots, a slow epilation gives bare roots whereas an increase in the rate of epilation increases the proportion of ensheathed roots. As the rate of epilation increases, the proportion of fractured hair shafts increases. These findings are relevant to epilation used as a diagnostic procedure because it is not possible to have both a high proportion of well-formed ensheathed anagen roots without some breakages.
