C-arm CT during superselective intra-arterial infusion chemotherapy was useful to determine the arterial supply of head and neck carcinoma. C-arm CT may replace conventional CT during superselective arteriography in this procedure.

Although platysma myocutaneous flap (PTMCF) is suitable for a small intraoral defect, combination with neck dissection (ND) decreases the viability. Therefore, a version of PTMCF was devised to increase the viability. This version consists of three points: preservation of the external jugular vein (EJV), preservation of the facial artery after skeletonization from the submandibular gland, and a new incision around the flap. This procedure was applied to 21 patients with intraoral cancer. All 21 patients underwent some kind of ND. The average viable area of transferred skin was 80%. This rate was significantly better than that for 46 previous cases using Farr’s modification with ND, in which the facial artery was divided. Viability of the flaps was analyzed by the vessels preserved, especially by EJV. ND is not a contraindication with this version.

The thicknesses of three dermal flaps, platysma, forearm, and fibula, which are often used for oropharyngeal reconstruction, were measured in 21 subjects using 15 MHz Doppler ultrasonography. The mean (SD) thicknesses were 2.2 (0.3), 3.1 (0.5), and 3.8 (0.6) mm, respectively. The free peroneal skin flap from the leg was used in 14 patients with head and neck cancer. These flaps were successfully transplanted in 13 of 14 patients (93%) with no problems at the donor site. This flap offers many advantages, including its distance from the head and neck, its cosmetic superiority to a forearm flap, it allows two flaps with two cutaneous branches, it is possible to close the donor site primarily without a skin graft, and it has thin subcutaneous tissue. We found that the free peroneal skin flap is particularly useful for oropharyngeal reconstruction.
