Masseter muscle hypertrophy (MMH) is a benign,
unilateral or bilateral, painless enlargement. Treatment
protocols include surgical excision or a non-invasive
option, using botulinum toxin type A (BTX-A). There is
no study in the literature that measures this
dimensional change in the masseter muscle (MM). The
aim of this case report is to present changes in volume
and surface area in MM with three-dimensional closerange stereophotogrammetry (3DCS). For treatment 30
units of BTX-A was injected into the three points
hypertrophic muscle and patient records were taken to
compare with 3DCS with a non-metric Canon EOS 550 D
camera before and after injection. The changes in the
surface area and volume of this muscle were mapped
and the objective data were obtained.
This technique is useful for predicting the results of BTX-A
application, and can be a useful tool for better physicianpatient communication.
