    ABSTRACT: Various surgical interventions including esthetic surgery, salivary gland excision, and open reduction of fracture have been performed in the area around the mandibular angle and condyle. This study aimed to comprehensively review the anatomy of the neurovascular structures on the angle and condyle with recent anatomic and clinical research. We provide detailed information about the branching and distributing patterns of the neurovascular structures at the mandibular angle and condyle, with reported data of measurements and proportions from previous anatomical and clinical research. Our report should serve to help practitioners gain a better understanding of the area in order or reduce potential complications during local procedures. Reckless manipulation during mandibular angle reduction could mutilate arterial branches, not only from the facial artery, but also from the external carotid artery. The transverse facial artery and superficial temporal artery could be damaged during approach and incision in the condylar area. The marginal mandibular branch of the facial nerve can be easily damaged during submandibular gland excision or facial rejuvenation treatment. The main trunk of the facial nerve and its upper and lower distinct divisions have been damaged during parotidectomy, rhytidectomy, and open reductions of condylar fractures. By revisiting the information in the present study, surgeons will be able to more accurately prevent procedure-related complications, such as iatrogenic vascular accidents on the mandibular angle and condyle, complete and partial facial palsy, gustatory sweating (Frey syndrome), and traumatic neuroma after parotidectomy.

    ABSTRACT: This study was done to evaluate the effect of recombinant human bone morphogenic protein-2 (RhBMP-2) on enhancing the quality and quantity of regenerated bone when injected into distracted alveolar bone. Sixteen adult beagle dogs were assigned to either the control or rhBMP-2 group. After distraction was completed, an rhBMP-2 dose of 330µg in 0.33ml was slowly injected into the distracted alveolar crest of the mesial, middle, and distal parts of the alveolar bone in the experimental group. Histological and micro-computed tomography analyses of regenerated bone were done after 2 and 6 weeks of consolidation. After 6 weeks of consolidation, the vertical defect height of regenerated bone was significantly lower in the rhBMP-2 group (2.2 mm) than in the control group (3.4 mm) (P<0.05). Additionally, the width of the regenerated bone was significantly greater in the rhBMP-2 group (4.3 mm) than in the control group (2.8 mm) (P<0.05). The bone density and volume of regenerated bone in the rhBMP-2 group were denser and greater, respectively, than in the control group after 6 weeks of consolidation (P<0.001). Injection of rhBMP-2 into regenerated bone after a distraction osteogenesis procedure significantly increased bone volume in the dentoalveolar distraction site and improved both the width and height of the alveolar ridge and increased the bone density.

    ABSTRACT: The topography of the facial muscles differs between males and females and among individuals of the same gender. To explain the unique expressions that people can make, it is important to define the shapes of the muscle, their associations with the skin, and their relative functions. Three-dimensional (3D) motion-capture analysis, often used to study facial expression, was used in this study to identify characteristic skin movements in males and females when they made six representative basic expressions. The movements of 44 reflective markers (RMs) positioned on anatomical landmarks were measured. Their mean displacement was large in males [ranging from 14.31 mm (fear) to 41.15 mm (anger)], and 3.35-4.76 mm smaller in females [ranging from 9.55 mm (fear) to 37.80 mm (anger)]. The percentages of RMs involved in the ten highest mean maximum displacement values in making at least one expression were 47.6% in males and 61.9% in females. The movements of the RMs were larger in males than females but were more limited. Expanding our understanding of facial expression requires morphological studies of facial muscles and studies of related complex functionality. Conducting these together with quantitative analyses, as in the present study, will yield data valuable for medicine, dentistry, and engineering, for example, for surgical operations on facial regions, software for predicting changes in facial features and expressions after corrective surgery, and the development of face-mimicking robots.

    ABSTRACT: Abstract Mantle cell lymphoma has features of both indolent and aggressive non-Hodgkin lymphomas. Repeated relapses leading to treatment failure in mantle cell lymphoma patients might suggest the presence of cancer stem cells. A small cell population with CD45(+)/CD19(-) was previously reported to represent cancer stem cells. We evaluated the clinical relevance of CD45(+)/CD19(-) cells in bone marrow of patients with mantle cell lymphoma (n = 20). A CD45(+)/CD19(-) cell population was observed in newly diagnosed mantle cell lymphoma, and its percentage correlated with tumor cells in bone marrow (r = 0.832, P = 0.001), and the score on the simplified mantle cell lymphoma prognostic index (r = 0.675, P = 0.016). After treatment, CD45(+)/CD19(-) cells decreased (mean: 0.012%), and CD45(+)/CD19(-) cells (0.276%) was higher at relapse or progression than at diagnosis. In conclusion, a CD45(+)/CD19(-) cell population in bone marrow aspirates correlated with clinical outcome of patients with mantle cell lymphoma.

    ABSTRACT: Bone marrow biopsies are routinely performed for staging patients with B-cell non-Hodgkin lymphoma (NHL). In addition to histomorphological studies, ancillary tools may be needed for accurate diagnosis. We investigated the clinical utility of multiparameter flow cytometric examination of bone marrow aspirates. A total of 248 bone marrow specimens from 232 patients diagnosed with B-cell NHL were examined. Monoclonal antibodies directed against CD19, CD20, CD10 (or CD5), and κ and λ immunoglobulins were used. Multi-stage sequential gating was performed to select specific cells of interest, and the results were compared with bone marrow histology. The concordance rate between histomorphology and flow cytometry was 91.5% (n=227). Eight cases (3.2%) were detected by flow cytometry alone and were missed by histomorphology analysis, and 6 of these 8 cases showed minimal bone marrow involvement (0.09-2.2%). The diagnosis in these cases included large cell lymphoma (n=3), mantle cell lymphoma (n=3), and mucosa-associated lymphoid tissue (MALT) lymphoma (n=2). Thirteen cases were histopathologically positive and immunophenotypically negative, and the diagnoses in these cases included diffuse large cell lymphoma (n=7), T-cell/histiocyte-rich large B-cell lymphoma (n=2), anaplastic lymphoma kinase (ALK)-positive large B-cell lymphoma (n=1), follicular lymphoma (n=1), MALT lymphoma (n=1), and unclassifiable lymphoma (n=1). Multi-color flow cytometry can be a useful method for assessing bone marrow in staging NHL and also plays a complementary role, especially in detecting small numbers of lymphoma cells.

    ABSTRACT: The inferior labial artery (ILA) and horizontal labiomental artery (HLA) can be regarded as the main arteries used in the lower lip pedicle for the perioral reconstruction. However, the courses of the ILA and HLA are described in diverse ways, and there is no obvious standard for distinguishing between them. The aim of this study was to elucidate the distribution patterns of the ILA and HLA, and the significance of the HLA in the vascularization of the lower lip. Sixty-three hemifaces from 18 Korean and 19 Thai cadavers were used in this study. The distribution patterns of the arteries of the lower lip area were classified based on the assumption that the HLA travels in the middle of the lower lip area, while the ILA runs along the lower lip border. The arterial distribution pattern of the HLA was classified into three types (I-III): type I, where the HLA ran horizontally in the lower lip area; type II, where the HLA curved upward to the vermilion border of the lower lip; and type III, where the HLA bifurcated into two branches. The ILA was also classified into three types (A-C): type A, where the ILA was not observed; type B, ILA was ramified from facial artery at the level of mouth corner; and type C, ILA arose from the superior labial artery (SLA) and supplied the lower lip vermillion border. Types I, II, and III were observed in 52.4 % (33/63), 39.7 % (25/63), and 7.9 % (5/63) of cases, respectively; and types A, B, and C were observed in 52.4 % (33/63), 36.5 % (23/63), and 11.1 % (7/63) of cases. Consideration of the two artery classifications together revealed seven types: type IA (14.3 %, 9/63), type IB (28.6 %, 18/63), type IC (9.5 %, 6/63), type IIA (30.2 %, 19/63), type IIB (7.9 %, 5/63), type IIC (1.6 %, 1/63), and type III (7.9 %, 5/63). The distance between the HLA and the midpoint between the mouth corner and the inferior mandibular margin was 0.4 ± 3.1 mm (mean ± SD) inferior to this point. The ILA and HLA should be differentiated according to the location of their origin rather than their terminating areas. The HLA could be considered as the main artery supplying the lower lip mucosa.

    ABSTRACT: Previous studies have revealed a variation in the origin and distribution patterns of the facial artery. However, the relationship between the facial artery and the facial muscles has not been well described. The purpose of this study was to determine the facial artery depth and relationship with the facial musculature layer, which represents critical information for dermal filler injection and oral and maxillofacial surgery. Fifty-four embalmed adult faces from Korean cadavers (36 male and 18 female cadavers; mean age, 73.3 years) were used in this study. A detailed dissection was performed, with great care being taken to avoid damaging the facial artery underlying the facial skin and muscle. The facial artery was first categorized according to the patterns of its final arterial branches. The branching pattern was classified simply into three types: type I, nasolabial pattern (51.8 percent); type II, nasolabial pattern with an infraorbital trunk (29.6 percent); and type III, forehead pattern (18.6 percent). Each type was further subdivided according to the facial artery depth and relationship with the facial musculature layer as types Ia (37.0 percent), Ib (14.8 percent), IIa (16.7 percent), IIb (12.9 percent), IIIa (16.7 percent), and IIIb (1.9 percent). This study provides new anatomical insight into the relationships between the facial artery branches and the facial muscles, including providing useful information for clinical applications in the fields of oral and maxillofacial surgery.

    ABSTRACT: The superior labial artery, which is a branch of the facial artery, supplies the upper lip area. The aim of this study was to determine the distribution pattern of the superior labial artery and provide precise topographic information of the artery for dermal filler injection. Sixty hemifaces from 18 Korean and 18 Thai cadavers were used for this study. The various distribution patterns of the superior labial artery were classified according to its relationship with the facial artery. The course of the superior labial artery was classified into four types: type I (56.7 percent), in which the artery and the alar branch both arise directly and independently from the facial artery; type II (21.7 percent), in which the superior labial artery branches off from the facial artery and then gives off an alar branch; type III (15.0 percent), in which it is the terminal branch of the facial artery; and type IV (6.7 percent), in which the artery is absent. The origin of the superior labial artery was located 12.1 ± 3.1 mm (mean ± SD) lateral and at a variable angle of 42.8 ± 26.9 degrees relative to the mouth corner. The superior labial artery proceeded from the origin of the artery located within a 1.5-cm-side square superolateral to the mouth corner as running along the vermilion border of the upper lip to the facial sagittal midline at a depth of 3 mm. Thus, clinicians should be careful when injecting dermal filler into this area.

    ABSTRACT: The purpose of this study was to clarify the anatomic variation of the dorsalis pedis and first metatarsal arteries and to define the trabecular-to-cortical bone ratio (TBR) of the second metatarsal bone to ascertain their suitability as implants. Fifty-two specimens were prepared for this study. Each specimen was dissected on the dorsal side of the foot to search for the dorsalis pedis artery. Three types of dorsalis pedis artery were found: in type A, which was the most common, the artery continuously formed the first metatarsal artery; in type C, which was the second most common, the artery coursed below the first dorsal interosseous muscle; and in type B, the artery coursed from the lateral side. Five variations of the first metatarsal artery were identified: the most common was type IIb, in which the artery coursed below the first dorsal interosseous muscle; followed by type Ib, in which the artery coursed obliquely through the muscle; type Ic, in which the artery coursed parallel to the muscle; type IIa, in which the artery coursed above and below the muscle; and type Ia, in which the artery coursed only above the muscle. The second metatarsal bone was divided into 5 regions. There was no trabecular bone in regions 1 and 5. The TBR appeared to be lower in region 3 than in regions 2 and 4 and highest in region 2. All regions of the second metatarsal bone appear to be suitable as implants, but when placing the implant in the proximal end, care should be taken not to overheat the bone and to be wary of perforation when placing it on the middle side.

    ABSTRACT: The aim of this study was to clarify the definition of the anterior wall of the ulnar tunnel and to reveal the topographical characteristics of the various components of the ulnar tunnel. Twenty-two forearms from 11 embalmed cadavers (7 males, 4 females; mean age, 67.8 years) were carefully dissected. In all cases, the anterior wall of the ulnar tunnel comprised the hypothenar fascia, which originated from the tendon of the flexor carpi ulnaris muscle. The palmar carpal ligament, the distal extent of the antebrachial fascia, was located deep to the anterior wall and formed only the anterior boundary of the proximal hiatus of the ulnar tunnel. The hypothenar fascia was attached to the flexor retinaculum at 15.2 mm lateral to the pisiform bone. However, the palmar carpal ligament was attached to the flexor retinaculum just lateral to the ulnar artery; the distance between the attachment of the palmar carpal ligament and the pisiform bone was 8.7 mm. Anatomical variations potentially associated with ulnar nerve compression were observed. The accessory abductor digiti minimi muscle and the fibrous band crossing the ulnar nerve in the ulnar tunnel were found in 27 and 23 % of forearms, respectively. A more detailed description of the anterior wall of the ulnar tunnel than was previously available is presented herein, and topographic and metric data regarding each structure of the tunnel are reported.

    ABSTRACT: Hemophilia B is an X-linked bleeding disorder caused by deficient coagulation factor IX from a mutation in the F9 gene. Here, we report a family with two brothers having severe hemophilia B inherited from a mother with low-level somatic mosaicism of a F9 mutation. The proband was a 2-year-old boy with severe hemophilia B from a hemizygous mutation of F9, c.464G>A (p.Cys155Tyr). He was the first child and was considered a sporadic case based on the lack of family history of bleeding diathesis. His mother was tested for carrier status and was determined to be homozygous for wild-type genotypes (noncarrier). Subsequently, however, his brother was born and also had severe hemophilia B from Cys155Tyr. This prompted us to review the chromatogram of the mother, which revealed a small peak corresponding to the mutant genotype. On suspicion of somatic low-level mosaicism in the mother, we further performed allele-specific PCR and thymine and adenine cloning, and confirmed the presence of the mutant allele in the mother. To our knowledge, this is the first case of maternal somatic mosaicism for a cytosine-phosphate-guanine transition mutation in hemophilia B. The acknowledgment of somatic mosaicism and further molecular investigation are important in sporadic hemophilia B to deliver informative genetic counseling and risk assessment.

    ABSTRACT: BACKGROUND The botulinum neurotoxin Type A (BTX) injection into the masseter muscle often causes a change in the facial expression. There is as yet no precise anatomic evidence to support this etiologic factor of constrained facial expressions. OBJECTIVE The aim of this study was to clarify the location and boundaries of the risorius muscle and its topographical relationship with the surrounding structures. MATERIALS AND METHODS This study involved the dissection of 48 hemifaces. The locations of origin and insertion points of the risorius muscle were measured, and the masseter muscle was divided into 6 equally sized rectangular areas. RESULTS Cases where the masseter muscle was covered by the risorius muscle were classified into the following 4 types: in Type A, Area III was partially covered by the risorius (17.8%); in Type B, Area VI was partially covered (20.0%); in Type C, Areas III and VI were partially covered (53.3%); and in Type D, Areas II, III, and VI were covered (6.7%). CONCLUSION These findings suggest that the medial part of the masseter muscle represents a hazard zone into which the injection of BTX may affect the risorius muscle, potentially resulting in iatrogenic unnatural facial expressions.
