Analysis of condylar positioning in the temporomandibular joint following mandibular reconstruction: Introduction of a new classification system and assessment of influencing factors on displacement.

Objective: This study investigates the unsatisfactory outcomes observed in mandibular reconstruction procedures attributed to improper condylar positioning in the Temporomandibular Joint. It also proposes a systematic classification for post-reconstruction condylar positioning dissatisfaction.

Methods: A retrospective analysis was conducted on 337 patients who underwent tumor removal and mandibular reconstruction with vascularized osteocutaneous flaps.

Single vs. Double-Opposing Z-Plasty: Evaluating Their Impact on Palatoplasty Postoperative Outcomes.

Background: The double-opposing Z-plasty is a fundamental approach for cleft palate repair. Recently, some surgeons have begun implementing a single Z-Plasty, igniting discussions on the most effective technique for enhancing postoperative outcomes. Consequently, this study sought to evaluate the outcomes of employing single and double Z-plasties within the modified Sommerlad-Furlow technique.

Fibroblast regulates angiogenesis in assembled oral cancer organoid: A possible role of NNMT.

Objective: Tumour angiogenesis is affected by various cell types in the tumour microenvironment (TME), including cancer cells and cancer-associated fibroblasts (CAFs). Here, an assembled organoid model was generated to investigate the mechanism by which the TME regulates angiogenesis in oral squamous cell carcinoma (OSCC).

Materials And Methods: Secretion of vascular endothelial growth factor-A (VEGFA) was analysed to compare the proangiogenic properties of OSCC cells and corresponding CAFs.

Evaluation of late cleft palate repair by a modified technique without relaxing incisions.

Objective: To evaluate the postoperative outcomes together with analyzing the associated influencing factors following a late cleft palate repair by the Sommerlad-Furlow modified technique (S-F).

Materials And Methods: In a retrospective cohort, 320 consecutive patients with cleft palate, who received S-F technique between 2011 and 2017, were reviewed. The patients were divided into three age groups, less than one year (143), one to two years (113), and greater than 2 years (64).
