Orthognathic surgery for occlusal reconstruction of old malunited jaw fracture

Yokoo S., Komori T., Furudoi S., Shibuya Y., Tateishi C., Hashikawa K., Tahara S., Hanagaki H.

Language：Japanese Publisher：Kobe Journal of Medical Sciences

Old malunited jaw fractures of nine patients who underwent orthognathic surgery for occlusal reconstruction were clinically evaluated. Early surgery on fractures of the jaw is the optimal treatment when due attention must be paid to occlusion. Since occlusal revision surgery subsequent to inaccurate diagnosis and inappropriate surgery is certainly very difficult and often unsuccessful, surgeons need to pay special attention to this situation.

REFINEMENT OF SURGICAL PROCEDURES IN RADIAL FOREARM FREE FLAP TRANSFER

Publisher：Japan Society for Head and Neck Cancer

We have carried out about 600 head and neck reconstructions with radial forearm free flap transfer and basic/clinical studies on flap circulation and surgical procedures. Knowledge obtained and refinement of surgical procedures in flap elevation, venous anastomosis and donor site coverage introduced at Kobe University Hospital are as follows: 1) Deep and superficial venous systems of the flap are connected by including the cubital perforating vein in the venous pedicle. 2) Our studies have revealed that the deep venous system has dominant blood flow compared with the superficial system. Consequently, drainage of the former system is crucial in reducing venous disturbance of the flap. 3) “Network venous anastomosis”, where the two separate venous systems of the flap are anastomosed with the two venous systems of the neck (the internal and external jugular veins) including their connecting perforating vein, imitates the anatomical venous drainage in the forearm, providing a reliable, fail-safe drainage system. 4) Skin grafts preserving subdermal vascular networks provide aesthetically more optimal results in covering the donor site of the flap. 5) Fixation of skin grafts to the donor site of the flap with polyurethane foam and film without using the tie-over procedure is an easy and time-saving method requiring no assistants.

This study reviews reconstruction of complex three-dimensional oral and maxillofacial defects using the single free radial forearm flap or the single free rectus abdominis musculocutaneous flap. Between 1996 and 2003, 124 patients underwent oral and maxillofacial reconstruction in the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine. Outcomes for 22 patients who underwent three-dimensional reconstruction of multiple surfaces were evaluated. Reconstruction was performed after resection of malignant tumors in all 22 patients. Single FAFs were utilized for 11 patients and single RAMs for the remaining 11. Flap survival rate was 100%. No major donor morbidity was observed, and all surviving patients (20/22) were able to perform normal daily living activities. Single FAF and RAM are useful materials for one-stage reconstruction of complex three-dimensional oral and maxillofacial defects requiring replacement of skin, mucosa, and intervening soft tissues. Good to excellent aesthetic results can be attained in most patients. (J. Oral Sci. 46, 65-70, 2004)

Do multiple venous anastomoses reduce risk of thrombosis in free-flap transfer? Efficacy of dual anastomoses of separate venous systems

Ichinose A, Terashi H, Nakahara M, Sugimoto I, Hashikawa K, Nomura T, Ogata N, Yokoo S, Tahara S

ANNALS OF PLASTIC SURGERY Vol. 52 ( 1 ) page： 61 - 63 2004.1

Language：Japanese Publisher：Annals of Plastic Surgery

Whether or not multiple venous anastomoses reduce the risk of free-flap failure is a subject of controversy. We report here, for the first time, on the importance of selecting 2 separate venous systems of the flap for dual anastomoses. The efficacy of multiple anastomoses was verified through a retrospective review of 310 cases of the free radial forearm flap transfer. Dual anastomoses of separate venous systems (the superficial and the deep) showed a lower incidence of venous insufficiency than single anastomosis did (0.7% versus 7.5%; P < 0.05). On the other hand, dual anastomoses of a sole venous system showed no significant difference in the incidence of venous insufficiency compared with single anastomosis (11.5% versus 7.5%; P = 0.48). Our results suggest that dual venous anastomoses of separate venous systems is conducive to reduced risk of flap failure and affords protection against venous catastrophe through a self-compensating mechanism that obviates thrombosis of either anastomosis.

Endoscopic endonasal reduction for blowout fracture of the medial orbital wall

Sanno T, Tahara S, Nomura T, Hashikawa K

PLASTIC AND RECONSTRUCTIVE SURGERY Vol. 112 ( 5 ) page： 1228 - 1237 2003.10

Language：Japanese Publisher：Plastic and Reconstructive Surgery

Endoscopic endonasal reductions have been addressed in 63 patients with blowout fracture of the medial orbital wall since 1992. The operations were carried out under general anesthesia with a magnified operative space projected on a television monitor by a charge coupled device video camera attached to the endoscope. The middle nasal turbinate was fractured toward the nasal septum, the uncinate process was cut off, and the bulla was opened. The ethmoidal bony partition and the mucous membrane were removed; however, the fractured bone chips of the medial orbital wall were preserved. The herniated orbital contents were pressed back into the orbital cavity, and the medial wall was set with 2-mm-thick bent silicone plates placed in the ethmoidal sinus. The plates were removed in the outpatient clinic 2 months after the operation. The surgical results of 21 patients treated with endoscopic reduction were compared with those of four patients treated with transfacial reduction with an iliac bone graft. All of the patients had isolated medial wall fracture and became aware of diplopia within 15 degrees in any direction from the primary position (straight gaze) before the operation; the follow-up period covered 6 months. The patients were classified into two categories according to postoperative double vision: "good," indicating no double vision or diplopia of more than 45 degrees, and "poor," diplopia of less than 45 degrees. Improvement of diplopia was observed in all patients without any complication. Of the 21 patients who underwent endoscopic reductions, 17 were classified as "good" and four as "poor." On the other hand, of the four patients who underwent transfacial reductions, three were classified as "good" and one as "poor." Significant differences were not observed between the surgical results of our two methods. Endoscopic endonasal reduction showed greater aesthetic advantages and, moreover, required no grafting. This technique is suggested as one of the most reasonable treatments of medial orbital wall fractures.

Importance of the deep vein in the drainage of a radial forearm flap: A haemodynamic study

The free radial forearm flap has two drainage veins, the cutaneous and the deep, but no established consensus has been reached on the selection of the drainage pedicle. In our study, the flow volumes of the veins were examined by colour Doppler ultrasonography after 20 forearm flaps had been raised. The volume through the deep vein was significantly higher than that through the cutaneous vein (p < 0.01). In comparing the total flow (both veins open), the flow rate through the deep vein alone (cutaneous vein occluded) was over 80% in 13 cases, 60%-80% in seven, and under 60% in none; that through the cutaneous vein alone (deep vein occluded) was 60%-80% in eight, 40%-60% in eight, under 40% in four, and over 80% in none. Our results show the importance of the deep vein, as indicated by its high drainage capacity from the early stages of flap transfer.
