Article Abstract
Objectives: The aim of this study was to evaluate the effect of phenylketonuria (PKU) on mandibular bone structure by comparing the bone of PKU patients with healthy controls using fractal analysis (FA) and the radiomorphometric indices of mandibular cortical width (MCW) and mandibular cortical index (MCI).
Study Design: In total, 32 patients with PKU were analyzed and compared with the control participants. Regions of interest in panoramic radiographs were selected and the fractal dimension (FD) obtained from FA was calculated. MCW was defined as the cortical thickness of the inferior border of the mandible at the level of the mental foramen. MCI classified the endosteal edge of the mandibular cortex as C1: straight and sharp, C2: the presence lacunar resorption spaces, and C3: distinctly porous and severely eroded. The significance level was P < .05.
Results: All FD and MCW values were significantly lower in the PKU patients. The prevalence of C1 was significantly lower and prevalence of C2 was significantly higher in the PKU group.
Conclusions: The differences in FD and radiomorphometric indices between patients with PKU and healthy controls may indicate a potential impact of PKU on mandibular bone structure.

Backgrounds And Aims: Submental skin laxity (SSL), manifesting as sagging skin and double chin, can significantly affect patients' self-perception and social interactions. While surgical treatments exist, non-invasive methods are increasingly sought for their minimal recovery time. This study assesses the safety and effectiveness of a novel microwave-based device for treating SSL, aiming to provide long-term improvements in skin tightness and appearance.

Objectives: This study analyzed the differences in the upper airway of patients with skeletal Class III high-angle malocclusion with and without mandibular deviation, and further investigated whether there are differences in the changes in upper airway space after orthognathic surgery between the two groups.
Materials And Methods: 15 patients with skeletal Class III high-angle malocclusion and mandibular deviation, and 15 patients without mandibular deviation were selected to explore the impact of mandibular deviation on the upper airway. Additionally, 16 patients with mandibular deviation undergoing orthodontic-orthognathic combined treatment, and 13 patients without mandibular deviation, were selected to investigate the differences in the changes in upper airway space after orthognathic surgery between the two groups.

Introduction: The aim of this article is to present the diagnostic and therapeutic approach to unilateral posterior vertical insufficiency.
Material And Methods: The authors describe the management protocol.
Results: Posterior vertical insufficiency (PVI) manifests clinically as obliquity of the maxillo-mandibular occlusal plane and bicommissural line, and deviation of the chin.

Introduction: The cant of the occlusal plane in the frontal plane reflects facial asymmetry. Its treatment requires close collaboration between the orthodontist and the maxillofacial surgeon. In case of mild cant, treatment consists in coordination of dental arches followed by mandibular osteotomy.

Stafne bone cavity, also known as static bone cavity, is a rare bony defect on the lingual side of the mandible. It rarely shows progressive changes, and requires only follow-up bservation. This article described a case of progressive enlargement of a Stafne bone cavity and analyzed the causes of its progress by reviewing relevant literature.
