Unilateral hypoglossal nerve palsy following orthognathic surgery: A case report and literature review.

Introduction: Hypoglossal nerve palsy (HNP) can be caused by nerve damage from the central nerve to a peripheral nerve, and individuals with multiple factors could be predisposed to HNP. We report a case of isolated unilateral HNP after orthognathic surgery.

Case Presentation: A 56-year-old Japanese woman complained of jaw distortion and malocclusion.

The Role of Hedgehog Signaling in the Melanoma Tumor Bone Microenvironment.

A crucial regulator in melanoma progression and treatment resistance is tumor microenvironments, and Hedgehog (Hh) signals activated in a tumor bone microenvironment are a potential new therapeutic target. The mechanism of bone destruction by melanomas involving Hh/Gli signaling in such a tumor microenvironment is unknown. Here, we analyzed surgically resected oral malignant melanoma specimens and observed that Sonic Hedgehog, Gli1, and Gli2 were highly expressed in tumor cells, vasculatures, and osteoclasts.

Stem Cell-Based Tissue Engineering for Cleft Defects: Systematic Review and Meta-Analysis.

This study aimed to analyze the efficacy of stem cell-based tissue engineering for the treatment of alveolar cleft (AC) and cleft palate (CP) defects in animal models. Systematic review and meta-analysis. Preclinical studies on alveolar cleft repair in maxillofacial practice.

Association between impaired healing after orthognathic surgery and irritable bowel syndrome: A case report and literature review.

Introduction: In the disease irritable bowel syndrome (IBS), gastrointestinal function is worsened even though no organic abnormalities are observed in the gastrointestinal mucosa. We report the case of an orthognathic surgery patient with suspected irritable bowel syndrome.

Case: In September 2017, a 15-year-old Japanese female was referred to us with dental crowding, malocclusion, and mandibular protrusion.

Surgical procedures for correcting vertical maxillary excess: A review.

Introduction: Vertical maxillary excess, a common orthodontic problem that leads to long faces and open bites, can be repositioned with a Le Fort I osteotomy. However, the Le Fort I osteotomy poses the risk of a variety of complications including descending palatine artery (DPA) injury. Although several Le Fort I osteotomy modifications were reported to avoid complications associated with this osteotomy, only a few of such studies were conducted in Japan, and details remain scarce.
