Peripheral nerve injuries remain a challenge for reconstructive surgeons with many patients obtaining suboptimal results. Understanding the level of injury is imperative for successful repair. Current methods for distinguishing healthy from damaged nerve are time consuming and possess limited efficacy. Confocal laser endomicroscopy (CLE) is an emerging optical biopsy technology that enables dynamic, high resolution, sub-surface imaging of live tissue. Porcine sciatic nerve was either left undamaged or briefly clamped to simulate injury. Diluted fluorescein was applied topically to the nerve. CLE imaging was performed by direct contact of the probe with nerve tissue. Images representative of both damaged and undamaged nerve fibers were collected and compared to routine H&E histology. Optical biopsy of undamaged nerve revealed bands of longitudinal nerve fibers, distinct from surrounding adipose and connective tissue. When damaged, these bands appear truncated and terminate in blebs of opacity. H&E staining revealed similar features in damaged nerve fibers. These results prompt development of a protocol for imaging peripheral nerves intraoperatively. To this end, improving surgeons' ability to understand the level of injury through real-time imaging will allow for faster and more informed operative decisions than the current standard permits.

There are many women who want larger and brighter eyes that will give a favorable impression. Surgical methods that make the eye larger and brighter include double eyelidplasty, epicanthoplasty, as well as lateral canthoplasty. Double eyelidplasty produces changes in the vertical dimension of the eyes, whereas epicanthoplasty and lateral canthoplasty create changes in the horizontal dimension of the eyes. Epicanthoplasty, a surgical procedure which enlarges the eye horizontally, is performed at the inner corner of the eye, whereas lateral canthoplasty enlarges the outer edge of the eye. In particular, if the slant of the palpebral fissure is raised and the horizontal dimension of the palpebral fissure is short, adjusting the slant of the palpebral fissure through lateral canthoplasty can achieve an enlargement of eye width and smoother features. Depending on the patient's condition, even better results can be achieved if this procedure is performed in conjunction with other procedures, such as double eyelid-plasty, epicanthoplasty, eye roll formation surgery, fat graft, and facial bone contouring surgery. In this paper, the authors will introduce in detail their surgical method for a cosmetic lateral canthoplasty that lengthens the lateral canthal angle and corrects the outer tail of the eyes, in order to ease the unfavorable impression.

It is interesting that the costume in the period of romanticism was very fantastic and peculiar in its aspects. The romanticism in the fashion theme of these days' mode represents the image of this France romanticism. Costume has unseparable relations with the style of art in the same period. Especially, plastic art has logical connection with costume because it is an art through silhouette, line, color and texture felt by visional and solid feelings. This kind of study is important in order to understand the fashion of today, to anticipate the fashion in future and to get recognition of costume as a genre of arts. This study is to analyse and compare the general features in the grown-ups' everyday clothes of France from 1815 to 1850 when costume in the period of romanticism reached its peaks with the art of architecture, paintings, sculpture and technology, with the aid of documentary recordings. The above study explain that costume is expressed by the same plastic art of the period if it coexists in the same cultural background. Finally, we can plan the costume in future on an artistic dimension by understanding correctly the characteristics of plastic art which modern costume pursue from an artistic point of view.

Purpose: Basosquamous carcinoma is a rare malignancy, with features of both basal cell carcinoma and squamous cell carcinoma. It is considered as aggressive tumor with a high risk of recurrence and metastases. Authors report a case of basosquamous cell carcinoma. Methods: A 72 year-old man, who had an erythematous ulcer on his left auricle, described a slow growing lesion, starting at the posterior surface of the superior helix with a steady increase in size during the past 10 years. At operation, auricular cartilage was grossly invaded by the tumor and was, therefore, amputated with tumor-free margins. Results: Histopathologic examination was revealed a basosquamous cell carcinoma. On positron emission tomography/computed tomography (PET/CT) and neck CT were negative for signs of further nodal involvement or metastases to other organs. At follow-up 6 months later, his wounds were noted to be well healed, with no evidence of local recurrence or identifiable metastases. Conclusion: Because basosquamous cell carcinoma has a significant potential to recur and metastasize, surgical excision for this type of carcinoma should be more extensive than that performed for conventional basal cell carcinoma or squamous cell carcinoma. In addition, regional lymph nodes should be monitored and close follow-up should be carried out.

Lung cancer is one of high mortality malignancy. It is known that skin metastasis from lung cancer is uncommon. We report a very rare case of finger tip metastasis from double primary cancer of the lung and lower lip. A 79 year-old man diagnosed with non small cell lung cancer presented with protruding solid mass in his lower lip. It showed central necrosis with purulent discharge. It had appeared rapidly growing features. Simultaneously, another solid mass accompanying painful swelling without skin lesion was found in his left middle finger tip. Both two solid masses were moderately differentiated squamous cell carcinomas. Lower lip mass was a primary cancer, while middle finger tip mass was diagnosed with clinically metastatic cancer from lung or lower lip, which means that it had double primary cancer origin.

In lower abdominal flap representing transverse rectus abdominis musculocutaneous (TRAM) flap or deep inferior epigastric perforator (DIEP) flap, superficial inferior epigastric vein (SIEV) exists as superficial and independent venous system from deep system. The superficial venous drainage is dominant despite a dominant deep arterial supply in anterior abdominal wall. As TRAM or DIEP flaps began to be widely used for breast reconstruction, venous congestion issue has been arisen. Many clinical series in regard to venous congestion despite patent microvascular anastomosis site were reported. Venous congestion could be divided in two conditions by the area of venous congestion and each condition is from different anatomical causes. First, if venous congestion was shown in whole flap, it is due to the connection between SIEV and vena comitantes of DIEP. Second, if venous congestion is limited in above midline (Hartrampf zone II), it is due to problem in venous midline crossover. In this article, the authors reviewed the role of SIEV in lower abdominal flap based on the various anatomic and clinical studies. The contents are mainly categorized into four main issues; basic anatomy of SIEV, the two cause of venous congestion, connection between SIEV and vena comitantes of DIEP, and midline crossover of SIEV.

An epidermal cyst, also known as an epidermoid cyst or epidermal inclusion cyst, is the most prevalent type of cutaneous cyst. This non-cancerous lesion can appear anywhere on the body, typically presenting as an asymptomatic dermal nodule with a visible central punctum. In the case presented herein, an epidermal cyst with uncommon features was misdiagnosed as a lymphatic malformation based on preoperative magnetic resonance imaging (MRI). A 61-year-old man came to us with a swollen left cheek that had been present for 11 months. The preoperative MRI revealed a 3×3.8×4.6 cm lobulated cystic lesion with thin rim enhancement in the left masticator space. The initial differential diagnosis pointed toward a lymphatic malformation. We proceeded with surgical excision of the lesion via an intraoral approach, and the specimen was sent to the pathology department. The pathological diagnosis revealed a ruptured epidermal cyst, indicating that the initial diagnosis of a lymphatic malformation based on preoperative MRI was incorrect. Epidermal cysts located under the muscle with no visible central punctum are uncommon, but should be considered if a patient presents with facial swelling.

Background The objective of this study was to assess the attractive facial features of the Indian population. We tried to evaluate subjective ratings of facial attractiveness and identify which facial aesthetic subunits were important for facial attractiveness. Methods A cross-sectional study was conducted of 150 samples (referred to as candidates). Frontal photographs were analyzed. An orthodontist, a prosthodontist, an oral surgeon, a dentist, an artist, a photographer and two laymen (estimators) subjectively evaluated candidates' faces using visual analog scale (VAS) scores. As an objective method for facial analysis, we used balanced angular proportional analysis (BAPA). Using SAS 10.1 (SAS Institute Inc.), the Turkey's studentized range test and Pearson correlation analysis were performed to detect between-group differences in VAS scores (Experiment 1), to identify correlations between VAS scores and BAPA scores (Experiment 2), and to analyze the characteristic features of facial attractiveness and gender differences (Experiment 3); the significance level was set at P=0.05. Results Experiment 1 revealed some differences in VAS scores according to professional characteristics. In Experiment 2, BAPA scores were found to behave similarly to subjective ratings of facial beauty, but showed a relatively weak correlation coefficient with the VAS scores. Experiment 3 found that the decisive factors for facial attractiveness were different for men and women. Composite images of attractive Indian male and female faces were constructed. Conclusions Our photogrammetric study, statistical analysis, and average composite faces of an Indian population provide valuable information about subjective perceptions of facial beauty and attractive facial structures in the Indian population.

Objectives：Cutaneous angiosarcoma is an infrequent but aggressive neoplasm involving the skin of the face and scalp. Unfamiliarity with the clinical manifestations of cutaneous angiosarcoma frequently leads to misdiagnosis and delay in treatment. Complete surgical resection requires the performance of preoperative staging biopsies to determine the true extent of the neoplasm. Intraoperative frozen section analysis to determine the adequacy of the surgical resection is unreliable due to the high false negative rate. Material and Methods：In five scalp angiosarcoma cases, mapping biopsies were performed at far from the suspected edge of the neoplasm. On permanent pathology, we obtained tumor free margin with occasional focal involvement of the tumor. Results：Frozen-section analysis of the resected margins is inconclusive, for the subtle diagnostic features of angiosarcoma are distorted by the tissue processing required for frozen-section analysis. The characteristic dermal vessels lined by their malignant cells are collapsed by the freezing process. This results in a high rate of false-negative reports and possibly leads to incomplete resection of the neoplasm. Conclusion：Our recommendation is to establish the margins of the tumor by performing preoperative evaluations by mapping biopsies.

Purpose: Primary malignant lymphomas of the salivary glands are uncommon, representing only 1.7% to 3.1% of all salivary neoplasms and 0.6% to 5% of all tumors and tumor-like lesions of the parotid gland. Lymphomas of the parotid glands are usually manifestations of a systemic disease process but primary lymphomas of the parotid glands are rare. Most of these lesions are classified as extranodal non-Hodgkin's lymphoma. We report the clinicopathological features of primary malignant lymphoma of the parotid gland based on an analysis of our cases. Methods: The subject was a 48-year-old male patient with a malignant lymphoma originating in the parotid gland, which had been slowly increasing in size over previous 6 months. The diagnosis was established by MRI and a superficial lobectomy. After diagnosis, the patient was referred to an oncologist for staging and medical treatment. Results: The stage was IIIA. The patient was treated with chemotherapy following surgery with rituximab and CHOP (Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). The tumor was controlled successfully by chemotherapy. The patient was followed up for 1 year with no relapse. Conclusion: A case of primary non-Hodgkin's lymphoma of the parotid gland was treated with a superficial parotidectomy and chemotherapy. The disease was well controlled after a 1 year follow-up.
