Simultaneous diagnosis and resection of orofacial rhabdomyosarcoma with frozen section biopsy: a case report

Rhabdomyosarcoma is the most common soft tissue sarcoma in children, accounting for 4.5% of all cases of cancer in childhood. Although the head and neck are the most common sites of rhabdomyosarcoma, oral lesions are relatively rare and account for only 10% to 12% of head and neck rhabdomyosarcoma cases. This is a case report of a girl aged 2 years and 1 month who initially presented with an upper lip mass that invaded the oral mucosa, oral skin, and nostril skin, causing narrowing of the airway. Through our case, we show that rapidly growing small round cell malignancies, especially rhabdomyosarcoma, can be effectively diagnosed and treated at the same time using primary resection with intraoperative frozen section biopsy and that the time spent waiting for the results of preoperative biopsy can be saved in this way, particularly when the patient’s symptoms are intensifying rapidly and require immediate operation.

Epithelioid sarcoma associated with neurofibromatosis type I

In general, patients with neurofibromatosis type I have a higher risk than those with other types of neurofibromatosis of developing soft-tissue sarcomas related to the nervous system. We here present a 42-year-old man with neurofibromatosis type I who developed a protruding mass over only 2 weeks. The histopathological diagnosis was epithelioid sarcoma. Epithelioid sarcomas are rare and, to the best of our knowledge, no epithelioid sarcomas have been reported in patients with neurofibromatosis type I. Radical excision of the primary lesion was performed and postoperative radiotherapy and chemotherapy administered, as is recommended for epithelioid sarcoma. Our case emphasizes that patients with neurofibromatosis type I may develop malignant tumors

Malignant melanoma on a thermal burn scar

Chronic burn scars often cause various skin malignancies at rates of up to 2%. These lesions are usually squamous cell carcinomas, but rarely, malignant melanoma is reported. We report a 67-year-old male with a malignant melanoma on a burn scar with regional metastasis. This patient presented an ulcerative lesion only in 2 weeks. After histopathological diagnosis, we performed only palliative surgery on patient's demand, and followed up the subsequent deterioration course. Our case reemphasizes the need for rapid diagnosis and treatment when suspect lesions are present on chronic burn scar. Also, physician should be in mind and inform the patient about malignant melanoma and its aggressive course.

New anthropometric data for preoperative planning in orbital wall fracture treatment: the use of eyelid drooping

BACKGROUND: The presence of enophthalmos is an important determinant in the decision of orbital wall fracture surgery. We proposed eyelid drooping as a new anthropometric diagnostic measure and analyzed whether eyelid drooping is associated with enophthalmos. METHODS: This retrospective study was performed from January 2014 to December 2016. A total of 75 patients with blowout fractures were studied. One experimenter measured the degree of enophthalmos using a Hertel exophthalmometer at 1 week after trauma and at 3 months after surgery. The height change of the upper eyelid was measured using the marginal reflex distance (MRD) on both sides, and the degree of eyelid drooping was calculated by comparing the two lengths. We analyzed statistically the correlation between enophthalmos and eyelid drooping. RESULTS: We found a highly significant correlation between the degree of enophthalmos and the reduction rate of MRD (RRM, as an indicator of eyelid drooping) at 1 week after trauma (r = 0.845). Approximately 2.0 mm of enophthalmos was associated with a 30.8% reduction in MRD on the affected side as compared with the normal side. At 3 months after surgery, patients showed improved eyelid appearance, with a moderate association between enophthalmos and RRM. CONCLUSION: We demonstrated that the degree of enophthalmos, measured using an exophthalmometer, is associated with a change in the height of the upper eyelid. Thus, upper eyelid drooping can be used as another indicator for orbital wall fracture surgery. Compared with conventional methods, measurements of eyelid drooping are easy to perform, offering a great advantage and understanding to the patient.

Pyogenic Granuloma: A Retrospective Analysis of Cases Treated Over a 10-Year

BACKGROUND: Pyogenic granuloma (PG) is a benign vascular lesion of the mucosa and skin. Recent studies of the epidemiology of PG are rare. We aimed to retrospectively analyze characteristics of PG cases in South Korea. METHODS: We reviewed the medical records of 155 patients treated for PG between March 2005 and May 2014. The male-to-female ratio was 1:1.2 (70 males, 85 females). The mean age of patients was 35.3 years. RESULTS: A high occurrence was observed in the first and third decades in males, and the fourth to fifth decades in females. There was a statistically significant difference between genders according to age group (p<0.05). The average lesion diameter was 0.84±0.46 cm (long axis). The most frequently involved site was the face (n=47). Bleeding was the primary complication (n=41). PG was mostly treated with excisional biopsy (n=74). The recurrence rate was 7.7% (n=12). CONCLUSION: We concluded that most common site of PG was the face, the age of female with PG is higher than previous studies, and finger is associated with trauma more than other sites. The most recent epidemiological information on PG of this study will support the treatment and diagnosis of PG and future research objectives.

Safety of a Single Venous Anastomosis in Anterolateral Thigh Free Flap for Extremity Reconstruction

PURPOSE: The main cause of flap loss in microsurgical tissue transfer is venous insufficiency. Whether or not multiple venous anastomoses prevents vascular thrombosis and reduces the risk of flap failure remains controversial. Some researchers are in favor of performing dual venous anastomoses, but the counterargument holds that performing a single venous anastomosis does provide advantages. MATERIALS AND METHODS: We carried out a retrospective analysis of 15 cases of anterolateral thigh free flap for extremity reconstruction performed between January 2011 and December 2013. The patients were categorized into two groups: group A that received a single venous anastomosis and group B that received dual venous anastomoses. The time of the anastomosis, size of the flap, complications of the flap, and survival rate of each group were analyzed. RESULTS: The total microsurgical time in the single venous anastomosis group ranged from 28 to 43 minutes (mean 35.9 minutes). The total time in the dual anastomoses group ranged from 50 to 64 minutes (mean 55.7 minutes). No statistically significant difference was found between the two groups with regards to postoperative complications and flap failure. CONCLUSION: Our study suggests that the use of a single venous anastomosis in the venous drainage of anterolateral thigh free flaps is a safe and feasible option for extremity reconstruction and provides shorter operative time and easy flap dissection.

Analysis of 809 Facial Bone Fractures in a Pediatric and Adolescent Population

BACKGROUND: Facial fractures are infrequent in children and adolescents and have different clinical features from those in adults. The low incidence in children and adolescents reflects the flexibility and underdevelopment of their facial skeletons, as well as their more protected environments. Only a few reports have reviewed such patients in Korea. The authors performed a retrospective study to analyze the characteristics of facial fractures in the Korean pediatric population. METHODS: We conducted a retrospective review on a series of 741 patients, aged <18 years, with facial fractures who had been treated at our hospital between 2006 and 2010. The following parameters were evaluated: age, sex, cause, location and type of fractures, associated injuries, treatment and complications. RESULTS: A total of 741 consecutive patients met the inclusion criteria. The ratio of boys to girls was 5.7:1. Facial fractures most commonly occurred in patients between 13 and 15 years of age (36.3%). The most common causes of injury was violence. The nasal fracture was the most common type of fracture (69%) and the blowout fracture was the second most common (20%). Associated injuries occurred in 156 patients (21%). CONCLUSIONS: The incidence of pediatric facial fractures caused by violence is high in Korea. Our results show that as age increases, etiological factors and fracture patterns gradually shift towards those found in adults. This study provides an overview of facial fractures in these age groups that helps illustrate the trends and characteristics of the fractures and may be helpful in further evaluation and management.

Different Perceptions of Facial Attractiveness According to Race and Gender

There have been few studies investigating the differences in the perception of facial attractiveness according to gender, races and ethnicity. This study was conducted to determine whether different races or genders show actual differences in the perception of beauty. Using 5 composite faces of different races, this survey was designed on 486 participants from different races and ethnicities. Photographs of the composite faces were displayed on a large poster at Incheon International Airport and passersby were asked to take part in the survey regarding which composite face was the most attractive. Data were statistically analyzed to determine differences in beauty perception in terms of gender, race and ethnicity. There were significant differences in the perception of the most attractive face and the least attractive face according to gender. There were significant differences in the perception of the most and least attractive face according to race. Multivariate analysis also revealed that there were different perceptions of facial attractiveness according to ethnic backgrounds. The results of this study suggest that the perception of facial attractiveness may differ according to gender, race and ethnicity, and that some unique or peculiar patterns of beauty perception may exist.

Comparison of the Multidetector-row Computed Tomographic Angiography Axial and Coronal Planes' Usefulness for Detecting Thoracodorsal Artery Perforators

BACKGROUND: During the planning of a thoracodorsal artery perforator (TDAP) free flap, preoperative multidetector-row computed tomographic (MDCT) angiography is valuable for predicting the locations of perforators. However, CT-based perforator mapping of the thoracodorsal artery is not easy because of its small diameter. Thus, we evaluated 1-mm-thick MDCT images in multiple planes to search for reliable perforators accurately. METHODS: Between July 2010 and October 2011, 19 consecutive patients (13 males, 6 females) who underwent MDCT prior to TDAP free flap operations were enrolled in this study. Patients ranged in age from 10 to 75 years (mean, 39.3 years). MDCT images were acquired at a thickness of 1 mm in the axial, coronal, and sagittal planes. RESULTS: The thoracodorsal artery perforators were detected in all 19 cases. The reliable perforators originating from the descending branch were found in 14 cases, of which 6 had transverse branches. The former were well identified in the coronal view, and the latter in the axial view. The location of the most reliable perforators on MDCT images corresponded well with the surgical findings. CONCLUSIONS: Though MDCT has been widely used in performing the abdominal perforator free flap for detecting reliable perforating vessels, it is not popular in the TDAP free flap. The results of this study suggest that multiple planes of MDCT may increase the probability of detecting the most reliable perforators, along with decreasing the probability of missing available vessels.

Absorbable Plate as a Perpendicular Strut for Acute Saddle Nose Deformities

BACKGROUND: Nasal pyramid fractures accompanied by saddle nose deformities are not easily corrected by closed reduction. We used an absorbable plate as a perpendicular strut to support the collapsed "keystone area" and obtained good results. METHODS: Between September 2008 and June 2011, 18 patients who had nasal pyramid fractures with saddle nose deformities underwent surgery. Pre- and postoperative facial computed tomographic images and photographs were taken to estimate outcomes. The operative technique included the mucoperichondrial dissection of the nasal septum, insertion of an absorbable plate prepared to an appropriate length to support the "keystone area", and fixation of the absorbable plate strut to the cartilaginous septum. RESULTS: Functional and esthetic outcomes were satisfactory in all patients. Eleven patients assessed the postoperative appearance of the external nose as 'markedly improved' and 7 patients as 'improved'. The 5 surgeons scored the results as a mean of 4.5 on a 5-point scale. CONCLUSIONS: The use of an absorbable plate as a perpendicular strut requires no additional procedures because the plate is gradually absorbed. The mechanical strength provided by a buttress between the "keystone area" and the maxillary crest lasts for a long time before the strut is absorbed.

Tip Plasty using Biodegradable Plate as a Columella Strut

PURPOSE: Most surgeons have used autogenous cartilage for columella strut graft. But the supply of autogenous cartilage is often limited. So, this study is to investigate the usefulness of biodegradable plate as columella strut material. METHODS: We studied 19 patients who have secondary cleft nasal deformity. Patients were divided into two groups. Group A patients who were not closed their growth plate underwent columella strut graft only with biodegradable plate through endonasal approach. The biodegradable plate was inserted between nasal tip and anterior nasal spine. Group B patients were closed their growth plate. They had an operation for columella strut graft with biodegradable plate fixed with autogenous conchal cartilage. If nasal tip projection was insufficient, we performed additionally onlay graft on nasal tip with autogenous soft tissue or remnant cartilage. RESULTS: As a result of mean 14 months follow-up, we achieved a good nasal tip projection, narrowing of interalar distance and symmetrical nostril shape. No specific complications were reported except 2 cases, which were the extrusion of biodegradable plate into the nasal cavity and Staphylococcus aureus infection. CONCLUSION: The columella strut graft using biodegradable plate is simple and effective method. Biodegradable plate can be a good substitute for columella strut in patients who can not use autogenous cartilages.

Evaluation of Influence of Individual Facial Aesthetic Subunits on the Congnition of Facial Attractiveness in Public

PURPOSE: Authors tried to analyze the influence of individual facial aesthetic subunits on the cognition of facial attractiveness in public and suggest a mathematical model which explain the facial attractiveness. METHODS: Independent facial aesthetic subunits are extracted from facial photographs from three women(11 frontal and 7 lateral aesthetic subunits). Each facial subunits of three women are rated in terms of relative rank by 164 peoples(68 man and 96 woman, average age was 32.4, and ranged +/- 9.8 years). chi-square-test and categorical regression analysis were performed. RESULTS: There was no difference in the aesthetic preference in terms of ages or sexes in large. Beautification of individual aesthetic subunits can predict the overall facial attractiveness up to 42.1% in frontal face(Adjusted R2=0.421, F=6.39, p=0.000<0.05) and 22.7% in lateral face (Adjusted R2=0.227, F=4.42, p=0.000<0.05). Aesthetic appearance of eyes(p=0.001), upper face(p=0.034) in frontal face and midface(p=0.000) in lateral face are statistically important factors in the cognition of facial attractiveness. CONCLUSION: Authors experimently proved that harmony and balance among facial aesthetic subunits are the most important factors, in embarking on facial aesthetic plastic surgery, for better enhancement of facial attractiveness.

The Fate of Calvarial Bone Graft in Nasal Tip Plasty Patients Followed Up for Over 10 Years

PURPOSE: In order to maintain corrected nasal tip projection, strong support is important. Authors used calvarial bone graft method for this purpose. Patients were followed up about permanency of the bone graft for a long time. METHODS: From 1995 to 1998, author performed calvarial bone graft on 30 adult patients with secondary cleft lip and nose deformity. Patients were observed for 34 months. There were no specific complications, and results were satisfactory. We could confirm the permanence of the calvarial bone graft in 3 patients by photography and radiologic studies for 10 years follow-up. RESULTS: None of the patients showed size change or displacement. But the portion of graft facing the tip was absorbed resulting in loss of tip projection and short nose in two patients. One patient had fracture on the middle of the graft. This caused depression from lower portion of the dorsum to the tip. CONCLUSION: Despite of autogenous grafts such as calvarial bone, absorption of the bone may occur when compressed with tension for a long period. And the graft in the nasal tip not having any contact with the nasal bone may cause absorption of the graft.

Surgical Correction of Nostril Base and Nostril Sill Depression in Unilateral Secondary Cleft Lip Nose Deformity

PURPOSE: Most unilateral secondary cleft lip nose deformities have depressed nostril base and sill on the cleft side. To obtain a symmetric nose, correction of the recession on nostril is critical. The authors have worked out effective methods to elevate the nostril of the cleft side according to the extent of the depression. METHODS: A total of 115 unilateral secondary cleft lip nose deformity patients with nostril depression were evaluated. Data were acquired from patients' charts and photography with special reference to the height difference of the nostrils between the cleft side and the non-cleft side. Patients were divided into three groups based on the difference and operated with various techniques :(1) mild degree( 3mm) with graft, C-flap and suspension suture. Follow-up period averaged 21.3 months. RESULTS: Forty-six patients(40 percent) were in mild group, and forty-two(37 percent) were in moderate. In twenty-seven patients(23 percent), nostril recession was more than 3mm. The elevated nostril base and sill were maintained without height alteration during follow-up. CONCLUSION: The symmetry of the nostril base, especially projection of nostril sill influences successful correction of unilateral cleft lip nose deformity. Our tolerable techniques can be applied to most deformities with nostril depression and can present a new guideline.

Correction of Hump-nose Depending on Size of Hump

Nose is the most three dimensional structure located on the central portion of the face. Therefore, the nasal shape is one of the most important factors on deciding upon one's impression. Hump-nose is characterized by nasal hump, acute tip angle, drooping or/and under-projection of tip, and broad nasal dorsum. Because of these characteristics, recently more patients with hump-nose are inclined to correct their problematic nose. The purpose of this study was to classify hump-nose according to hump size and provide proper operating methods in each group. From August 2003 to August 2005, in 46 cases, we classified the hump nose into three groups, small(group A; n=30), medium(group B; n=6), and large(group C; n=10) in accordance with size and location of hump and in each group we effectively corrected the hump with our proper operating methods. In the large group, one case of tension nose temporarily appeared but soon improved and we obtained satisfactory results in the other cases.

More Effective Facial Scar Revision in Asian

Facial scar is very stressful for patients and physicians, especially in the case of non-parallel to relaxed skin tension line (RSTL). In general, for long facial scar not parallel to RSTL, Z-plasty or W-plasty has been performed to change the direction of scar or divide it into multiple segmented scar. These methods would be suboptimal, however, in the instance of Asian skin prone to scar formation. So, we experienced good results for scar revision through scar excision and solid subcutaneous- dermal repair to minimize scar widening despite of leaving linear type of scar. From July 2004 to March 2007, our methods were undergone for facial scar longer than 3cm in 84 patients. All scars were excised along the scar margin and subcutaneous tissue and dermis were repaired using single layer of subcutaneous-dermal stitch with 4-0 or 5-0 PDS to elevate wound margin 3-4mm higher than adjacent skin surface. Skin was repaired with 6-0 Prolene. The rate of satisfaction was over 89%(75 of 84 patients), the mean scar widening was 0.61+/-0.20 mm, and secondary operations were made in 3 patients. The Asian skin has some characteristics such as thick skin, increased melanin, energetic proliferation of fibroblast, and vigorous collagen formation, etc. Because of characteristics of Asian skin mentioned above, the linear pattern repair, technically easier than Z-plasty or W-plasty, would be superior to them in terms of the results. The essentially important point for scar revision in linear pattern is very strong subcutaneous-dermal repair to make elevation of wound margin enough for tolerating the skin tension and preventing scar widening.

Correction of Notching Deformity of Soft Triangle Using V-Y Advancement Flap after Rhinoplasty

Soft triangle of nose is composed of only two skin layer between dome of alar cartilage and nostril. If soft triangle is damaged in rhinoplasty, the notching deformity can be caused by scar contracture. For correction of notching deformity, some methods such as composite graft or filler injection have been introduced, however these methods have some disadvantages like need for donor site or unpredictable long term results. We could correct notching deformity of soft triangle with V-Y advancement flap on the vestibular skin with great ease. Our method was undergone for 3 patients with notching deformity among 120 patients who had rhinoplasty during from March 2004 to February 2007 in our clinic. The elapse of time to definitive deformity was mean 2 months and the corrective procedure was performed 4 months later after formation of definitive deformity. Under the local anesthesia, the triangular flap proximally based was designed on the vestibular skin and this flap was sutured in V-Y fashion. There was no complication and no recurrence. This method is thought to be very useful because of some advantages: easy controlling advancement of flap according to the severity of deformity, no need for donor site, predictable outcome, and economic.
