The pterional craniotomy is the one of the most frequently used surgical procedure in
the field of neurosurgery. Two main methods(muscle-splitting and interfascial technique)
of the temporalis dissection and its modifications have been described in detail in the
neurosurgical literature. But the muscle spilitting technique may limit the exposure of
the skull base and the interfascial dissection carries a significant risk of frontalis nerve
palsy. The authors have used the subfascial dissection method and compared it with
other two technique in the aspects of functional and cosmetic outcomes.
A total of 253 consecutive patients who underwent pterional crainotomies between
January 1990 and Jung 1995 were selected. Among these, interfascial technique was
used in 92 patients, muscle-splitting method in 93 patients, and subfascial temporalis
dissection in 68 patients. The patients were examined to compare the incidence of facial
nerve palsy, the presence of chewing difficulty, temporal asymmetry and the degree of
maximal mouth opening.
The interfascial approach showed the worst outcome in preserving frontalis nerve and
maintaining temporal symmetry(p<0.05). There were no significant differences among
these three techniques in maximal mouth opening and chewing difficulties.
In conclusion, the subfascial temporalis dissection technique enable many surgeons to
perform pterional craniotomies without fear of frontalis nerve injury while obtaining
satisfactory operative exposure. We believe this is the choice of dissection method when
performing pterional craniotomy.
