Objective: To evaluate the clinical and radiographic efficacy of micro crestal flap-alveolar ridge preservation following extraction of mandibular molars with severe periodontitis compared with natural healing, and to preliminarily propose the surgical indication.
Methods: A retrospective analysis was conducted on clinical data from patients with mandibular molars with severe periodontitis either receiving micro crestal flap-alveolar ridge preservation (MCF-ARP group) or undergoing natural healing in department of periodontology, Peking University School and Hospital of Stomatology from September 2013 to June 2021. Cone-beam computed tomography scannings performed before/immediately after extraction (as baseline) and repeated before implantation (after the extraction socket healing) were used to measure the ridge width, height and volumetric changes of the sockets, and the proportion of guided bone regeneration (GBR) during implant therapy were compared between the two groups.

The anterolateral thigh (ALT) flap is a commonly used donor site for reconstructive surger, especially in head and neck reconstructions. The flap's success is primarily determined by the quality and quantity of its perforating vessels, which is why clinicians typically prefer harvesting from a healthy leg with intact vascular anatomy. Poliomyelitis typically causes unilateral lower limb paralysis, resulting in muscle atrophy and deformities.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

Article Synopsis
- The study discusses alternatives to buccal mucosa for reconstructive surgery in complex urethral strictures, given situations where buccal grafts may be inadequate or inappropriate.
- A 57-year-old male patient with a urethral stricture underwent urethroplasty utilizing a new VIVENDI graft, which is aldehyde-free, alongside a surgical technique involving a dorsal inlay.
- Post-surgery, the patient experienced no complications and reported satisfactory voiding, with follow-up planned for three months to assess recovery.
Neurovascular anatomy of the platysma muscle for blepharoptosis repair: a cadaveric study.
Surg Radiol Anat

Department of Plastic and Reconstructive Surgery, University of Health Sciences Türkiye, Gülhane Training and Research Hospital, Ankara, Turkey.
Purpose: This study aimed to define a new surgical method using a neurotized platysma free flap to provide dynamic reanimation, enhanced functional recovery, and low morbidity for blepharoptosis repair.
Methods: Ten hemifaces and neck halves of five formalin-fixed cadavers were included in the study. The origin of the neurovascular structures of the pedicle was identified at the submandibular triangle.
