We have confirmed the phototoxicity of orange flower absolute, studied the phototoxic ingredient and developed a method to eliminate it. To confirm the phototoxicity, we tested French orange flower absolute, Moroccan absolute and Egyptian absolute with Hartley strain guinea Pig under UV irradiation ranging from 320400 nm supplied with fluorescent lamps. Using a combination of isolation techniques including HPLC and IR, we were able to confirm that the phototoxic agent was bergapten. The development of a non-phototoxic orange flower absolute using ion exchange chromatography is described.

Open and closed rhinoplasty are two main approaches to perform nasal modifications. According to current literature, there is no current consensus among plastic surgeons and otolaryngologists on which technique is preferred in terms of aesthetic result, complications, and patient satisfaction. This study uses published research to determine whether open or closed rhinoplasty leads to superior patient outcomes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews were followed and a literature search was conducted in four databases based on our search strategy. Articles were then imported into COVIDENCE where they underwent primary screening and full-text review. Twenty articles were selected in this study after 243 articles were screened. There were 4 case series, 12 retrospective cohort studies, 1 prospective cohort study, 1 case-control, and 2 outcomes research. There were three cosmetic studies, eight functional studies, and nine studies that included both cosmetic and functional components. Sixteen studies utilized both open and closed rhinoplasty and four utilized open rhinoplasty. Both techniques demonstrated high patient and provider satisfaction and no advantage was found between techniques. Based on available studies, we cannot conclude if there is a preference between open or closed rhinoplasty in terms of which technique leads to better patient outcomes. Several studies determined that open rhinoplasty and closed rhinoplasty leads to comparative patient satisfaction. To make outcome reporting more reliable and uniform among studies, authors should look to utilize the Nasal Obstruction and Septoplasty Effectiveness scale and the Rhinoplasty Outcome Evaluation.

With the growing interest in skincare and maintenance, there are increasing numbers of studies on the classification of skin type and the factors influencing each type. This study presents a novel methodology by using data mining, for the determination of the relationships between skin type, lifestyle, and patterns of cosmetic utilization. Eight skin-specific factors, which are moisture, sebum in U-zone (both cheeks), sebum in T-zone (forehead, nose, and chin), pore, melanin, wrinkle, acne, hemoglobin, were measured in 1,246 subjects living in South Korea, in conjunction with a questionnaire survey analyzing their lifestyles and pattern of cosmetic utilization. Using various multivariate statistical methods and data mining techniques, we classified the skin types based on the skin-specific values, determined the relationship between skin type and lifestyle, and accordingly sorted the subjects into clusters. Logistic regression analysis revealed gender-related differences in the skin; therefore, separate analyses were performed for males and females. Using the Gaussian Mixture Modeling (GMM) technique, we classified the subjects based on skin type (two male and four female). Using the ANOVA and decision tree techniques, we attempted to characterize the relationship between each skin type and the lifestyles of the subjects. Menstruation, eating habits, stress, and smoking were identified as the major factors affecting the skin.

Purpose: The aim of this study was to systematically screen the literature for studies reporting cosmetic material in the oral and maxillofacial complex to shed light on the types of cosmetic materials, their radiographic appearance, and possible complications. Materials and Methods: Five electronic databases were reviewed for eligible studies. The general search terms were "cosmetic," "filler," "face," and "radiograph." Demographics, material types, clinical and radiographic presentation, and complications were recorded. Results: Thirty-one studies with 53 cases met the inclusion criteria. The mean age was 52.6±15.4 years with a 4 : 3 female-to-male ratio. The most common material was calcium hydroxyapatite (CaHa) (n=14, 26.4%), found incidentally. The materials were generally located within the upper cheek and zygoma (n=35, 66.0%), radiographically well-defined (n=44, 83%), and had no effects on the surrounding structures (n=27, 50.9%). The internal structure was radiopaque (calcification, hyperdensity) for gold wires, CaHa, bone implants, and secondary calcification or ossification. Outdated cosmetic materials or non-conservative techniques were infiltrative, had effects on the surrounding structures, and presented with clinical signs, symptoms, or complications. Conclusion: Conventional radiography, cone-beam computed tomography, and multi-detector computed tomography are useful to differentiate several cosmetic materials. Their magnetic resonance imaging appearance was highly variable. The infrequent inclusion of cosmetic materials in the differential diagnosis implies that medical and dental specialists may be unfamiliar with the radiographic appearance of these materials in the face.

For surgical minimalism to reduce iatrogenic traumatization, a supraorbital keyhole approach has already been successfully applied to treat many unruptured anterior circulation aneurysms. However, using this minimal approach also raises several technical concerns due to the small cranial opening and cosmetic impact of a facial incision. Yet, such technical limitations can be overcome by using favorable surgical indications, slender surgical instruments, and optimized surgical techniques, while excellent cosmetic outcomes can be achieved using a short skin incision located <1 cm from the supraorbital margin, reconstruction of any bone defects around the bone flap, and meticulous wound closure. Thus, given such reassuring surgical results, in terms of the clipping status, neurological effects, and cosmetic outcomes, any concerns can be transitioned into confidence.

Background and Objectives: The most commonly used incision for parotidectomy is modified Blair incision, but it has unsatisfactory cosmetic result due to long exposed scar in the neck. Therefore, we introduce an alternative approach with more acceptable scar named modified facelift incision. We report it's techniques, indications and disadvantages with our experiences. Materials and Methods: During the 1999, 15 patients were underwent parotidectomies using modified facelift incision. We studied the postoperative complications and the cosmetic results respectively. Results: There were 11 benign tumors, 3 malignant tumors, and 1 chronic inflammation. Total parotidectomy was performed in 2 malignant tumors and chronic parotitis patients. The others has superficial parotidectomy. In terms of operation field, there was no difference between classical incision and facelift incision. Partial facial nerve palsy was noted in 2 cases, who required sacrifice of branches of facial nerve because of malignant tumor invasion. There were no specific complications associated with this type of approach. Postoperative cosmetic results were satisfactory in all cases. Conclusion: Modified facelift incision provides better cosmetic result than conventional incision without narrowing of operation field. We believe that it is a safe alternative approach to all parotidectomy cases especially to women and patient with keloid skin. The only limitation of this incision is poor adaptability for combining neck dissection.

Objectives: Various techniques of endoscopic thyroidectomy have been developed in thyroid resection since 1998 in the aspect of excellent cosmetic viewpoint. Of them, we evaluated our experiences and advantages of gasless axillary approach technique for resection of dominant thyroid nodules. Material and Methods: Twenty-nine cases of thyroid nodules were operated by the technique of gasless axillary approach during one year from December 2003 to December 2004. Twenty four patients underwent total lobectomy and five patients were partial lobectomy. Results: The operation time of first case took 300 minutes, however it became gradually shortened with case experiences down to 100-120 minutes. Pathologically, nodular hyperplasia was twenty cases, follicular adenoma five cases, papillary carcinoma three patients, and Hashimoto's thyroiditis one patient. There was no case of conversion to open thyroidectomy. Three cases of postoperative hoarseness were recovered spontaneously in 3 months. Hospital stay was four days for most patients. The cosmetic result was excellent without visible scar in anterior neck and chest. Conclusion: Endoscopic thyroidectomy via gasless axillary approach shows excellent result in cosmetic view point with hidden incision scar at axilla, and shorter hospitalization. However a question of longer operation time for dissection of the long plane over pectoral muscle is still remained.
