Masseteric hypertrophy?: preliminary report

We report radiological and histological investigations of a patient who pre sented with the masseteric hypertrophy. Sections of the patient's masseter muscles were also investigated using a series of histological techniques. T he histological and morphometric analysis of the patient's masseter muscle showed numerous small fibres, which indicated that the masseteric enlargeme nt was not the result of classic fibre hypertrophy. We suggest that the use of the term 'hypertrophy' in this condition may be misleading.
