Purpose: To evaluate the application of the medial sural artery perforator flap (MSAPF) aided by preoperative ultrasonic perforator localization for postsurgical reconstruction of oral carcinoma.

Materials And Methods: From November 2013 to August 2014, 25 patients with oral carcinoma underwent postsurgical reconstruction after oral carcinoma resection using MSAPFs. To explore and locate the perforators, preoperative vascular ultrasound localization was used to find the MSAPs. The number and location of the perforators, length of the vascular pedicle, and thickness of the MSAPF were measured. Thirty-eight patients who underwent reconstruction with a radial forearm flap (RFF) and 21 patients who underwent reconstruction with an anterolateral thigh flap (ALTF) were selected for comparison.

Results: The number of MSAPs ranged from 1 to 4, and 52 perforators were found accurately using preoperative ultrasonic localization (92.86%). The distance from the perforator to the popliteal crease ranged from 6.2 to 17.1 cm (10.70 ± 2.31 cm); the distance from the perforator to the midline of the back of the calf ranged from 0.1 to 3.5 cm (1.83 ± 0.81 cm); and the pedicle length ranged from 6.8 to 12.5 cm (10.14 ± 1.51 cm). Compared with the RFF, and ALTF, the thickness, postoperative oral sensation, and function of the MSAPF were similar to those of the RFF but better than those of the ALTF. In appearance and function of the donor site, the MSAPF was similar to the ALTF, but better than the RFF.

Conclusion: The MSAPF is a good alternative for postsurgical reconstruction of oral carcinoma because of its anatomic structural stability, suitable thickness, minimal donor-site scar, and ideal functional recovery after surgery. Preoperative vascular ultrasonic localization is a feasible and advantageous method for preoperative mapping of the MSAP because of its high accuracy.

Background: The rapid growth of aesthetic medicine has led to an increased demand for non-surgical cosmetic procedures in the frontal region of the face. However, alongside this rise in popularity, there is a growing awareness of the potential complications associated with these procedures especially connected with fillers. The intricate vascular anatomy of the forehead, specifically the supratrochlear (STA) and supraorbital (SOA) arteries, poses significant risks if not thoroughly understood.

Objective: Osteoimmunology is an emerging field that explores the interplay between bone and the immune system. The immune system plays a critical role in the pathogenesis of diabetes and significantly affects bone homeostasis. Artesunate, a first-line treatment for malaria, is known for its low toxicity and multifunctional properties.

T cell-based immunotherapies have revolutionized cancer treatment, yet durable responses remain elusive. Here we show that PCIF1, an RNA N 2'-O-dimethyladenosine (mA) methyltransferase, negatively regulates CD8 T cell antitumor responses. Whole-body or T cell-specific Pcif1 knockout (KO) reduced tumor growth in mice.

Background: Hollowness in the anteromedial, buccal, and lateral cheek regions is a common concern in aesthetic medicine, often resulting from age-related volume loss and structural changes. Advanced filler injection techniques that incorporate a thorough understanding of facial anatomy are critical for achieving optimal and safe outcomes.

Objective: To review and detail anatomically guided filler injection techniques for addressing hollowness in specific cheek regions, considering facial anatomy, ethnic variations, and patient-specific aesthetic goals.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth.
