Background: Accessory infraorbital foramen (AIOF) can change the normal course of emerging branches of the infraorbital nerve and blood vessels exiting the infraorbital foramen (IOF). This study aimed to examine the AIOF, number of foramina, and their position in relation to IOF using cone-beam computed tomography (CBCT). Methods: We performed a retrospective CBCT assessment of hospital records between January 2018 and August 2022. The CBCT of 507 patients were examined to extract information on the prevalence, number, position, linear distance from the IOF, and diameter of AIOF in relation to demographic factors. Descriptive statistics were used to evaluate the prevalence of AIOF. Mean and standard deviation were used to calculate the linear distance and diameter of the AIOF, respectively. The AIOFs, its distribution, and number were compared between sexes and sides using the chi-square test. The independent t-test and Mann-Mann-Whitney test were used to compare the mean difference between the sexes and sides. Statistical significance was set at P < 0.05. Results: In this current study, the prevalence of AIOF was 7.1% (36 of the 507 patients). Additionally, the current study examined the number of foramina using a single foramen on each side and double foramina located bilaterally at a distance from the AIOF to the IOF. The mean AIOF diameter was also studied, and the AIOF position with respect to the IOF on CBCT was superomedial or inferomedial. There were no statistically significant associations between any of the parameters assessed in this study when comparing sex and sides. Conclusions: A greater number of patients with AIOF presented with a single foramen and unilateral occurrence, without a statistically significant difference. The AIOF was most commonly located superomedial to the IOF.

There was to purpose of this study improves analyzing cause that prosthesis brings bite engaging that is inaccurate in patient's mouth, when supposed that all conducts that do in operatory and dental laboratory are perfect. Impression did check bite by alginate impression material and polymerization style silicon impression material that use usually in presence at a sickbed Irreversibility, hydrocolloid, alginate impression material washed in flowing water and poured anhydrite after wait about 8 minutes so that region that charge interest after impression check bite may become undoing. And hydrophile property addition polymerization style impression material poured anhydrite after blow 30 considering impression material dwell time and H2 gas occurrence time (5~15 minute) after have washed in flowing water. I got each 7 models, result that manufactures total 28 and measures by third dimension measuring instrument (Meteo, Korea) following sequence curing in tray holder and floor 1, By Alginate impression when is hardened in tray holder and when is hardened in the floor after do check bite, SPH 4, SPH5 all as there is synonymy appeared(P<0.05). By in case do not use average 0.1741 in case use tray holder in 0.0447 SPH5s in case do not use average 0.2838 pastas in case use tray holder in SPH4 0.0309, When did not use both SPH4 and SPH5 tray holder, when used tray holder, 1 appeared more greatly. 2. By amity sex addition polymerization style silicon impression when is hardened in tray holder after do check bite and when is hardened in the floor SPH 4, a11 of the SPH5s very big synonymy be(P>0.05). And in case use tray holder in 0.000657 pasta SPH5s in case do not use average 0.000129 pastas in case use tray holder in SPH4 average 0.000114 pastas, by in case do not use 0.000757, I appeared more greatly when used tray when did not use both SPH4 and SPH5 tray holder, but 1 appeared is not level to keep in mind(Table 8~9). 3 SPH4 was looked very big mindfulness in model that manufacture doing impression check bite by Alginate and model that do impression check bite by amity sex accessory penalty silicon without using tray holder(P< 0.001). I use tray holder and SPH4 did not appear synonymy in model that manufacture doing impression check bite by Alginate and model that do impression check bite by amity sex accessory penalty silicon(P>0.05). Study finding of above when see synthesis Alginate certainly tray holder use must and I could know that hardening method does not exert big influence on volume stability if remove impression sieve of excess because amity sex accessory penalty silicon passes over tray, Also, Alginate impression material previewed can get heading a conspiracy style that volume stability of accessory penalty silicon impression material degree is if use tray holder.

Purpose: In the 1990s, skin island flap supplied by the vascular axis of the sensitive superficial nerves had been introduced. For example, neurocutaneous flaps supplied by the vascular axis of the sural nerve and saphenous nerve have been used. But the flap supplied by the vascular axis of superficial peroneal nerve has not been used commonly. Because there have been few anatomical reports about the superficial peroneal nerve accessory artery(SPNAA), we could not apply the neurocutaneous flap supplied by SPNAA. The aim of this study is to investigate the anatomy of SPNAA, number and location of its perforators, and septocutaneous perforators from the anterior tibial artery in anterior intermuscular septum. Methods: So, we dissected a total of eight cadavers. Measurements were made of the positions of the dissected arteries and perforators from the head of the fibula. Results: In all cadavers the superior lateral peroneal artery was originated from the anterior tibial artery and contributed SPNAA. Arising from the anterior tibial artery an average of 5.63 cm inferior to the fibular head, it varied from 10 cm to 16 cm in length. SPNAA gave off an average of 4.38 perforators to supply lateral aspect. In one case the inferior lateral peroneal artery was present and arose from the anterior tibial artery 18 cm inferior to the fibular head. There were an average of 3.38 direct septocutaneous perforators from the anterior tibial artery. Conclusion: Septocutaneous perforators from SPNAA mainly exist from proximal 1/6 to 3/5 of lower leg. In the distal 1/3 of lower leg where the accessory artery was disappeared, exist mainly direct septocutaneous perforators from the anterior tibial artery. Our results can be helpful to applications of the neurocutaneous flap using SPNAA or fasciocutaneous flap based on direct septocutaneous perforators.

Background/Objectives: This study aimed to evaluate the changes of uptake around the sternoclavicular joint (SCJ) according to 18F-FDG PET images in patients with head and neck cancer who underwent neck dissection. Materials & Methods: Retrospectively, the medical records of patients who received selective or comprehensive neck dissection were reviewed. Preoperative and 1-year postoperative 18F-FDG PET images, if available, were analyzed by nuclear medicine physicians in both qualitative and quantitative manners. Correlation between the changes of uptake around SCJ and perioperative data were statistically analyzed. Results: Thirty-seven patients satisfying the inclusion criteria were enrolled. Seven patients with increased uptake around SCJ on 1-year postoperative 18F-FDG PET showed a correlation with radical or comprehensive neck dissection, accessory nerve sacrifice, and high postoperative SUVmax. When 20 patients with increased uptake around SCJ according to quantitative measurement were compared with other patients without increased uptake, no parameter was significantly different, except postoperative SUVmax. Bivariate logistic regression analysis revealed that the clinical symptom (shoulder or sternal pain) was significantly correlated with the extent of neck dissection (OR 0.227, CI 0.053-0.966, p=0.045) and spinal accessory nerve sacrifice (OR 13.500, CI 1.189-153.331, p=0.036). Conclusions: Increased uptake around SCJ on 1-year postoperative 18 F-FDG PET was correlated with either the radical or comprehensive procedure, as well as with accessory nerve sacrifice. This suggests that subjective analysis of 18F-FDG PET can be used to detect subclinical shoulder instability.

Ultrastructural characteristics of the testis and spermatogenesis of Crassostrea gigas were investigated by Transmission and Scanning Electron microscope observations. The testis is a diffuse organ consisting of branching acini containing differentiating germ cells in a variety of stages. The acinus is surrounded by an intermitent layer of myoepithelial cells andis divided into subcompartments that are partially separated by pleomorphic accessory cells which remain in close contact with germ cells until late stages of development. these accessory cells contain a large quantity of glycogen particles and lipid droplets in the cytoplasm. Therefore, it is assumed that they are involved in the supplying of the nutrients for germ cell development, while any phenomena associated with phagocytosis of undischarged, residual sperms by lysosomes could be find in the cytoplasm of the accessory cells. The morphology of the spermatozoon has a primitive type and is similar to those of other bivalves. Mature spermatozoa consist of broad, cap-shaped acrosomal vesicle, subacrosomal material (containing axial rod embedded in a granular matrix), a oval nucleus showing deeply invaginated anteriorly, two triplet substructure centrioles surrounded by four spherical mitochondria, and satelite fibres appear to the distal centriole and plasma membrane. Spermatozoa of C. gigas resemble to those of other investigated ostreids. In particular, the anterior region of the acrosomal vesicle is transversely banded. It is assumed that differences in this acrosomal substructure are associated with the inability of fertilization between the genus Crassostrea and other genus species in Ostreidae. Therefore, we can use sperm morphology in the resolution of taxonomic relationships within the Ostreidea. The spermatozoon is approximately $42-47{\mu}m$ in length including an oval sperm nucleus (about $0.91{\mu}m$ in length), an acrosome (about $0.42{\mu}m$ in length) and tail flagellum ($40-45{\mu}m$). The axoneme of the sperm tail flagellum consists of nine pairs of microtubules at the periphery and a pair at the center. The axoneme of the sperm tail shows a 9 + 2 structure. These morphological charateristics of acrosomal vesicle belong to the family Ostreidae in the subclass Pteriomorphia.
