We investigated whether laryngeal images can be used to determine the pathological condition and effects of treatment in daily observations.
Fifty-four patients underwent intracordal fat injection with autologous fat between December 2003 and December 2012 at the Tokyo Hospital of Tokai University. The pre-operative laryngeal findings of these cases were assessed retrospectively.
In terms of the association between the laryngeal images and the pre- and post-operative maximum phonation times, a significant relationship was noted with both pre- and post-operative maximum phonation times in cases in which a gap was found on the posterior portion of the glottis. In particular, the presence of a gap in the posterior region of the glottis was related to the maximum phonation time, and significantly related to improvements in voice following autologous fat injection.
