BACKGROUND: Although the charting of normal intracranial volume (ICV) is fundamental for managing craniosynostosis, Asian norms in this regard are unknown. The purpose of this study was to establish a growth curve for ICVs in a large series of normal Asian children, providing reference values to guide corrective surgery. METHODS: A total of 124 normal children (male, 63; female, 61) and 41 children diagnosed with craniosynostoses were analyzed. Patients aged 0-8 years presenting to the emergency room and subjected to computed tomography (CT) for head trauma served as the reference cohort...

The purpose of this study was to develop a new method for enabling a robot to assist a surgeon in repositioning a bone segment to accurately transfer a preoperative virtual plan into the intraoperative phase in orthognathic surgery. We developed a robot system consisting of an arm with six degrees of freedom, a robot motion-controller, and a PC. An end-effector at the end of the robot arm transferred the movements of the robot arm to the patient's jawbone. The registration between the robot and CT image spaces was performed completely preoperatively, and the intraoperative registration could be finished using only position changes of the tracking tools at the robot end-effector and the patient's splint...

PURPOSE: Combined ablative and reconstructive oral maxillofacial surgery involves a multitude of anatomical and functional structures for speech and swallowing. Although there are a few methods to objectively examine swallowing function, this is not true for speech. We describe the development of an objective visualization and measurement tool for magnetic resonance imaging (MRI) to evaluate speech and its first application in a patient. MATERIAL AND METHODS: A total of 20 healthy patients and one patient with squamous cell carcinoma localized in the anterior floor of the mouth were included in the study...

Alveolar bone proper-derived mesenchymal stem/progenitor cells (AB-MSCs) and alveolar osteoblasts (OBs) are pivotal cells with positive attributes in regenerative medicine. During regenerative approaches, AB-MSCs may interact with their surrounding environment via their expressed toll-like-receptors (TLRs). This study aimed to depict for the first time the TLRs expression profile of AB-MSCs and OBs. Cells were isolated from human alveolar bone proper, and STRO-1-immunomagnetically sorted to segregate AB-MSCs and OBs...

Synkinetic movements are common among patients with incomplete recovery from facial palsy, with reported rates ranging from 9.1% to almost 100%. The authors propose the separation of the neural stimulus of the orbicularis oculi from that of the zygomatic muscular complex to treat eyelid closure/smiling synkinesis. This technique, associated with an anastomosis between the masseteric nerve and a central branch of the facial nerve, as well as with the use of a cross-facial nerve graft, resolves most of the spasms of the midface musculature, leading to a more relaxed tone when the mimic muscle is at rest and enhancing muscle excursion during voluntary and spontaneous smiling...

INTRODUCTION: Nodal yield has been demonstrated as a very promising marker for the prognostic outcome of patients with oral squamous cell carcinoma. However, studies on the importance of clinicopathological factors affecting the number of resected lymph nodes are rare, especially for patients without pathologically proven cervical lymph nodes. MATERIAL AND METHODS: Retrospective chart review of 264 patients with treatment naive oral squamous cell carcinoma and histopathologically proven negative cervical lymph node status, who received selective neck dissection of levels I-III/IV...

PURPOSE: Posttraumatic edema in facial bone fracture patients may interfere with the operation field and delay the schedule. Thus, swiftly reducing the edema alleviates patient discomfort and advances the operation date. Ice packing and compression bandages are often used for such a purpose, but such methods are often inconvenient for the face. In this study, we aim to analyze the effect of light-emitting diode (LED) (590/830 nm)-based low-level laser therapy (LLLT) in posttraumatic edema in facial bone fracture patients...

OBJECTIVE: Few studies evaluate condylar movement following mandibular reconstruction. The main objective of this study was to show that axial four-dimensional computed tomography (4DCT) could visualize bilateral protrusive condylar movement directly. We used axial 4DCT images to assess condylar protrusion in patients who underwent mandibular reconstruction. METHODS: We enrolled seven healthy volunteers (median age 30 years, range 27-38 years) and seven patients (median age 65 years, range 52-80 years), who underwent mandibulectomy (segmental in five, hemi in one, marginal in one) and free flap reconstruction (using the fibula in six and the radial forearm in one)...
