Professor Itaru Tsuge's research lab specializes in microsurgical reconstruction and advanced imaging techniques for flap surgery, focusing on improving outcomes in head and neck reconstruction. The lab investigates innovative flap designs—such as the free anterolateral thigh (ALT) flap and vascularized fibula osteo flaps—combined with preoperative imaging modalities like PAT (photoacoustic tomography) and S-factor imaging to enhance perforator selection and surgical precision. A key research direction involves developing image-guided, label-free methods to visualize subcutaneous vasculature, enabling more accurate and safer flap harvesting. The lab also emphasizes functional and cosmetic reconstruction in complex craniofacial defects, particularly following oncologic resections.

PAT imaging matched the intraoperative findings within 10 mm. Preoperative vascular evaluation allows for the creation of a vascular map for facilitating ALT flap surgeries.

Local flaps from the upper lip and cheeks have been the first choice for two-thirds to total resection of the lower lip. However, these local flap techniques involve many clinical problems, including small a mouth, drooling, scarring, and hypesthesia. The improvement of free anterolateral thigh (ALT) flap transfer can solve these problems with expansion of the application of free flaps for lower lip reconstruction. The patient in this case was a 56-year-old man with squamous cell carcinoma of th
This study demonstrates that the S-factor, a noninvasive, label-free imaging modality, can be used to successfully visualize subcutaneous arteries. This information can aid in selecting perforators for abdominal flap surgery.
We applied double-flap reconstruction with a vascularized fibula osteo flap and a Y-shaped anterolateral thigh (ALT) flap, which was separated into a fascial flap and a de-epithelialized fat flap to replace the temporomandibular joint capsule and temporal soft tissue volume, respectively. This technique achieved excellent functional and cosmetic results with acceptable operation time and donor site scarring. A 16-year-old girl had a rapidly growing mandibular osteosarcoma.

The diagnosis of necrotizing soft tissue infection (NSTI) caused by group A streptococcus (GAS) is challenging because clinical signs can be ambivalent, misleading, and sometimes absent.1 With the goal of improving the high mortality and morbidity rates, a rapid antigen detection test (RADT) for GAS helps shorten the time to decide on the need for surgical intervention and guide antibiotics treatment to a narrower spectrum.2 In this journal, we previously reported a 60-year-old woman with GAS-NS
