Abstract:
Objective To explore the accurate positioning of Kawase triangle area via intradural anterior subtemporal transpetrosal approach. Methods On 14 dry skulls, the highest point of arcuate eminence (A), the junction of lateral margin of petrous ridge and anterior margin of transverse sinus (J), the petrous apex (P), the outermost point of sulcus nervi petrosi superficialis majoris (B), the outermost point of foramen spinosum (C), the outermost point of foramen ovale (D), the outermost point of trigeminal notch (E), and the outermost point of foramen lacerum (F) were marked. The distances of JA, JB, JC, JD, JE and JF were measured using point J as reference point. Using the line (JP) between point J and point P as the baseline, the angles of baseline with JA, JB, JC, JD, JE, and JF were measured. Results There were no significant differences in the distances of JA, JB, JC, JD, JE and JF between the left and right sides (P>0.05). There were no significant differences in the angles of the baseline with JA, JB, JC, JD, JE, and JF between left and right sides (P>0.05). Conclusion Using point J and the baseline JP as referent indexes, bony structures can be precisely located via intradural anterior subtemporal transpetrosal approach to orientate the Kawase triangle area; this method can insure rapid, accurate and safe drilling of anterior petrosal bone and exposing of petroclival region.
