Accessory middle cerebral artery (MCA) is an infrequent vascular anomaly of the brain. Cerebral aneurysms associated with this anomalous artery are also very rare. To our knowledge, there have only been ten previous reports of an aneurysm associated with accessory MCA. The authors present two patients with accessory MCA-related aneurysms. A 38-year-old male and a 59-year-old female both presented with sudden-onset severe headache. In both patients, computed tomography (CT) scan revealed subarachnoid hemorrhage. A subsequent angiogram demonstrated an accessory MCA arising from the anterior cerebral artery (ACA) and a saccular aneurysm at the anterior communicating artery (ACoA) complex associated with an accessory MCA. Surgical clipping allowed for complete exclusion of the aneurysm from the arterial circulation. Based on our review of the ten cases of aneurysms associated with accessory MCA documented in the literature, we suggest that accessory MCA-related aneurysms can be classified according to whether the accessory MCA originates from the proximal A1 segment or from the ACoA complex. We also emphasize the importance of precise interpretation of preoperative angiograms and intraoperative precaution in determining the presence of this anomalous artery prior to temporary clip placement.

Purpose: This study was performed to examine distribution of accessory mandibular canal and its characteristics in mandibular third molars. Materials and methods: A total of 251 subjects (166 males and 85 females) having mandibular third molars bilaterally were included in the study. Cone-beam computed tomographic images were reviewed for bifid or trifid accessory mandibular canal. The prevalence of accessory mandibular canal was evaluated according to gender, side and its branching type. Proximity and crosssectional position of accessory mandibular canal to mandibular third molar was analyzed. Results: Accessory mandibular canals were found in 66 (26.3%) of 251 patients and 86 (17.1%) of 502 hemi-mandibles. Gender and sides showed no statistically significant differences in prevalence. Retromolar canal (46.1%) was the most common branching type. Proximity of accessory canal to mandibular third molars showed mean distance of 2.8 mm from third molar and a statistically significant difference was found among types of accessory canal. Dental canal was the closest to tooth among branching types and closer to tooth than main canal. On cross-sectional view, accessory canal was generally located on buccal side of mandibular third molar. Conclusion: Accessory mandibular canal was common and well detected with cone-beam computed tomography. Their localization is significant in all anesthetic and surgical procedures involving mandibular third molars.

1. Number of accessory chromosomes in the progenies of rye which were obtained from mother plants having 2, 4, and 6 accessory chromosomes by open pollination were observed. The result was shown in the Table 1. 2. Cross between the plant with 14 ordinary chromosomes having chromsome breakage and normal plant with 14 ordinary chromosomes was carried out. A plant among the progeny of this cross was found to have two accessory chromosomes in addition to 14 ordinary chromosomes. This phenomenon may be useful to postulzte the possible origin of accessory chromosome in rye.

A case of unruptured cerebral aneurysm at the junction of accessory middle cerebral artery and the distal portion of the $A_1$ segment of the anterior cerebral artery is reported. To the authors' knowledge, this is the first reported case of cerebral aneurysm developed at the junction of accessory middle cerebral artery, demonstrated on magnetic resonance angiography(MRA). The accessory middle cerebral artery is a rare vascular variant of middle cerebral artery. Furthermore, it is extremely rare for an aneurysm to be developed at the origin of the accessory middle cerebral artery. The development of the accessory middle cerebral artery is very important in surgery of cerebral aneurysm and collateral circulation of cerebral infarction. Review of the literature regarding the genesis and anatomical variation of the accessory middle cerebral artery is also presented.

Purpose: Accessory tragus is a fairly common congenital malformation and usually located at pretragal area. Surgical removal is a common treatment of accessory tragus irrespective of location and morphology. Most accessory tragi do not have depression site around them, but some do. So in those cases, simple surgical excision was not enough to promote the aesthetic facial appearance. For depression site remodeling, the excess amount of skin and cartilage need to be remained partially instead of total excision. This method can achieve the symmetric contour of pretragal area. The authors excised the epidermis and cartilaginous tissue totally and remained the dermis for reconstruction of the depression site around accessory tragus. The depression site is filled with dermal turnover flap. The purpose of this report is to present new idea to promote cosmetic result in treatment of accessory tragus containing the depression site. Methods: Two patients had a pair of accessory tragi at pretragal area. One was a common featured accessory tragus, but the other was different. Depression site was found around accessory tragus. After epidermis and cartilaginous tissue were removed from it, dermis component was used as turnover flap for reconstruction of depression site. Results: After accessory tragus was removed and depression site was reconstructed, facial contour and cosmetic result was achieved. Complication such as flap necrosis and wound dehiscence was not observed. Conclusion: The accessory tragus has variant morphology and degree of invasive depth. And some has a depression site around them. In those cases, simple surgical removal results in morphological distorsion and do not promote facial symmetry. The authors suggest dermal turnover flap as reconstruction method of the depression site. This method improves both surgical outcome and cosmetic result.

Accessory navicular is a congenital anomaly of the tuberosity of the navicular from a secondary ossification center. The accessory navicular is occasionally the source of pain and local tenderness over the medial side of midfoot. If conservative treatment fails for the painful accessory navicular, surgical treatment is required. There are several surgical option for accessory navicular, which vary from simple excision, percutaneous drilling, modified Kidner procedure and osteosynthesis of the accessory ossicle to the navicular body. In addition, symptomatic flatfoot deformity should be addressed concomitantly.

The purpose of this study was to find out differences of women's professionalism and attractiveness according to the perceiver's level of interest on accessory, the object person's age, and accessory wearing. Subjects were 178 college women in Seoul. The evaluation of the accessory wearing was divided into five dimensions: professionalism, attractiveness, loveliness, femininity, and individuality. The look of accessory wearing had significant influences on the evaluation of professionalism and attractiveness. The women in their 40's wearing the scarf on a jacket were evaluatedhigh in professionalism, attractiveness, and femininity. The 40's wearing the cap with a T-shirt were evaluatedlow in professionalism and attractiveness. The women in their 20's wearing the cap with a T-shirt were evaluatedhigh in attractiveness and loveliness. Wearing of scarf enhanced professionalism, femininity, and individuality, wearing necklace enhanced femininity, and wearing cap enhanced loveliness of women. Perceiver's level of interest on accessory gave significant influences on perception of professionalism and attractiveness. The object person's age gave significant influences on loveliness, femininity, and individuality. Professionalism, attractiveness, loveliness, and femininity had interaction effects according to object person's age and accessories. When women in their 40's wore scarf or necklace, their professionalism was raised more than those in their 20's. Therefore accessory wearing was more effective to the women in their 40's than the 20's.

Purpose: The mental foramen (MF) is an important anatomical structure during local anesthesia and surgical procedures in terms of achieving effective mental nerve blocks and avoiding injuries to the neurovascular bundles. Thus, understanding the anatomic features of the mandibular canal and accessory mental foramen in Korean could contribute to the surgical anatomic assessment. This study was to elucidate frequency, position and course of AMF (accessory mental foramen) in Korean using 3D cone beam computed tomography. Materials and Methods: The CBCT (Conbeam computed tomography) DICOM data (Alphard, Asahi, Japan) from 540 patients in korean were analyzed. We investigated images of 3D CBCT using Ondemand (CyberMed, Korea) software program on the incidence and anatomical characteristics of accessory foramen. Results: The accessory mental foramina were found in 17 patients. Accessory mental foramina exist predominantly in the apical area of the second premolar and posteroinferior area of the mental foramen. The accessory branches of the mandibular canal showed common characteristics in the course of gently sloping posterosuperior direction in the buccal surface area. The size of most AMF was obviously smaller than that of MF. Conclusion: We could identify frequency, position and course of AMF (accessory mental foramen) by the anatomical study of the accessory mental foramen using 3D cone beam CT in Korean.
