BACKGROUND: Cherubism is an autosomal dominant syndrome characterized by excessive bilateral maxillomandibular bony degeneration and fibrous tissue hyperplasia. Conservative management is the preferred treatment as cherubism has a self-limiting course. Functional or emotional disturbances may, however, demand surgical intervention. We report a patient who underwent surgical intervention. Method/Description: He had significant enlargement of lower cheeks and bilateral lower lid scleral show...

BACKGROUND: Sagittal resection of the mandible has been widely used to reduce the width of the lower face and is usually carried out in combination with a mandibular contouring procedure. However, the surgical outcomes of this procedure are unclear because sagittal resection is rarely performed as a single procedure. The authors clarify misunderstandings regarding this procedure and introduce an improved strategic approach for sagittal resection of the mandible. METHODS: Under general anesthesia, mandible contouring was performed first with a curved osteotomy, followed by sagittal resection of the outer cortex of mandible...

BACKGROUND: Autologous bone grafts are still the best materials for calvarial reconstruction. In the past, rib, iliac crest, and cranial bone have been used for the reconstruction of the calvarial defects. However, the use of mandibular outer cortex bone graft in calvarial defects reconstruction is poorly reported in literature. This study focused on using the mandibular outer cortex bone grafts for calvarial defects. METHODS: From October 2004 to July 2016, there were a total of 13 patients in this study who underwent cranioplasty with mandibular outer cortex bone grafts to reconstruction calvarial defects...

BACKGROUND: In patients with mild to moderate Parry-Romberg syndrome (PRS), plastic surgeons have mainly focused on the restoration of soft tissue deficiencies. While, bone deficits are easily overlooked. This study developed a new method combines the autologous mandibular outer cortex (MOC) grafting with fat grafting in mild to moderate patients with PRS, and apply computer-assisted techniques to improve the surgical outcomes and accuracy. METHODS: Seven patients with mild to moderate PRS were prospectively enrolled in the study...

The present study was aimed to determine the topographic relationship between root apex of the mesially and horizontally impacted mandibular third molar and lingual plate of mandible. The original cone beam computed tomography (CBCT) data of 364 teeth from 223 patients were retrospectively collected and analyzed. The topographic relationship between root apex and lingual plate on cross-sectional CBCT images was classified as non-contact (99), contact (145) and perforation (120). The cross-sectional morphology of lingual plate at the level of root apex was defined as parallel (28), undercut (38), slanted (29) and round (4)...

PURPOSE: Orthognathic surgery is an efficient procedure for cosmetic and functional aims. However, when functional improvement is achieved by mandibular or maxillary operations, additional esthetic corrections may be imperative for some patients. This study aims to introduce our primary practice of simultaneous facial bone contouring and orthognathic surgery for esthetic reasons. PATIENTS AND METHODS: Ten patients with dentofacial deformities as well as a prominent angle, asymmetric deformities, or a high zygoma and zygomatic arch were recruited from West China Hospital of Stomatology, Sichuan University (Chengdu, China), between January 1, 2014, and July 31, 2015...

Fractures of the mandibular angle account for 23 to 42% of all facial fractures with a high complication rate (0-32%). Although the ideal treatment remains debatable, two main procedures are commonly used to manage the majority of mandibular angle fractures that are open reduction and internal fixation by a noncompression miniplate placed on the external oblique ridge with or without a second miniplate on the outer cortex. The purpose of this study was to describe our management of mandibular angle fractures by two noncompression miniplates placed on the outer cortex via a transbuccal approach...

In this article, the authors present a practical surgical technique using the anatomical character of the inferior alveolar nerve to fully expose the mental nerve (MN) in narrowing genioplasty. During the procedure, a rectangular mandibular outer cortex adjacent to the mental foramen is removed before the osteotomy. The objective is to avoid the injury of the MN from the reciprocating saw or bur and offer abundant space for the surgical operation. The technique has a minimal learning curve and will be useful to plastic surgeons to minimize unintentional cutting or pulling injury to the MN in narrowing genioplasty...

BACKGROUND: Mandibular hypoplasia may result from congenital deformities or trauma or infection during the early stage of facial skeleton development. Deficiencies in the growth of the mandible can not only cause various degrees of facial deformity but also affect breathing and occlusal function. Here, we report our experiences with mandibular distraction combined with orthognathic surgical techniques for the treatment of severe adult mandibular hypoplasia. METHODS: Cephalometric analysis was conducted in all patients for quantitative evaluation...

The extraction of mandibular third molars is a common dental procedure. The complications include hemorrhage, pain, dental fracture, the displacement of teeth or fragments, iatrogenic damage or luxation of the second molar, neurologic injuries, soft tissue damage, subcutaneous emphysema, trismus, swelling, infection, and iatrogenic mandibular fracture. Fracture of the angle of the mandible associated with third molar removal is a rare but severe complication. This article describes a case of mandibular angle fracture associated with third molar extraction after mandibular angle osteotectomy, including a brief review of the literature...

PURPOSE: Mandible reconstruction with reconstruction plates requires bending the plates during the operation and fixation using the "standard method" (ST-method). The ST-method is limited when a pathological process has perforated the mandibular outer cortex. A transfer key method (TK-method) was developed where plates are pre-bent using a patient-specific mandible model and positioned on the mandible with the help of transfer keys. The ST-method and TK-method were compared in a clinical trial...

BACKGROUND: Various surgical options are reported to address the Asian 'squared face', characterized by a prominent mandibular angle (PMA) associated with an oversized chin deformity; but shortcomings lie in the requirement of multi-stage procedures with the risk of further revision surgery. We have developed a single-stage "Mandibular Angle-Body-Chin Curved Ostectomy (MABCCO) and Outer Cortex Grinding (OCG)" surgical technique to shorten the period of the surgical treatment and minimize the inherent surgical risks in the multi-staged procedures...

Osteochondroma of the mandibular condyle could cause secondary facial asymmetry; besides, it could affect the function of the temporomandibular joint (TMJ) and occlusion. Conventional treatments include total condylectomy or local resection of the lesion and condylar reconstruction. But it cannot effectively ameliorate the facial asymmetry. Thus, this article presents the application of combination surgeries including condylectomy, sliding vertical ramus osteotomy, and mandibular contouring in the treatments of this kind of disease...

PURPOSE: From an East Asian traditional esthetic viewpoint, a soft facial appearance seems to be more attractive. A prominent mandibular angle, a high zygomatic bone, and an inharmonious chin strongly lessen the attributes of femininity. Attention should be paid to the zygomatic projection and square mandible from the frontal view and the gonial angle and mental region configuration from the lateral view to obtain a slender oval face (melon seed face). PATIENTS AND METHODS: From January 2005 through December 2010, 47 patients underwent a combination of 4 operative techniques to reshape a square face: L-shaped osteotomy, V-line osteotomy, mandibular outer cortex splitting ostectomy, and sliding genioplasty...
