Usability of the middle temporal vein as a recipient vessel for free tissue transfer in skull-base reconstruction.

In skull-base reconstruction, finding appropriate recipient veins is difficult if the patient has undergone previous craniotomy or requires multiple drainage vessels, because of postoperative scarring and the limited number of veins in the temporal region. Therefore, we have used the middle temporal vein (MTV) to overcome these problems. We examined the presence and caliber of the MTV in 12 patients undergoing skull-base reconstruction. The MTV was identified in all cases and used for reconstruction, alone or with the superficial temporal vein (STV), in 8 patients without postoperative flap loss and was only measured in 4 patients. The caliber of the MTV was significantly greater than that of the STV, and there was no significant difference between the usage of the MTV and STV in the length of reconstruction time. Therefore, the MTV is of an appropriate caliber, and its use does not require complicated procedures as alternative recipient vessels.
