Abstract
BACKGROUND Epidemiological evidence has demonstrated a clear association between diabetes mellitus and increased risk of Alzheimer's disease (AD). Cerebral accumulation of phosphorylated tau aggregates, a cardinal neuropathological feature of AD, is associated with neurodegeneration and cognitive decline. Clinical and experimental studies indicate that diabetes mellitus affects the development of tau pathology; however, the underlying molecular mechanisms remain unknown. OBJECTIVE In the present study, we used a unique diabetic AD mouse model to investigate the changes in tau phosphorylation patterns occurring in the diabetic brain. DESIGN Tau-transgenic mice were fed a high-fat diet (n = 24) to model diabetes mellitus. These mice developed prominent obesity, severe insulin resistance, and mild hyperglycemia, which led to early-onset neurodegeneration and behavioral impairment associated with the accumulation of hyperphosphorylated tau aggregates. RESULTS Comprehensive phosphoproteomic analysis revealed a unique tau phosphorylation signature in the brains of mice with diabetic AD. Bioinformatic analysis of the phosphoproteomics data revealed putative tau-related kinases and cell signaling pathways involved in the interaction between diabetes mellitus and AD. CONCLUSION These findings offer potential novel targets that can be used to develop tau-based therapies and biomarkers for use in AD.

Abstract
Introduction Microtia reconstruction with autologous costal cartilage framework grafting is challenging because the three-dimensional structure of the ear is highly complex, and meeting the high aesthetic demands of patients can be difficult. If the skin flap overlying the framework is thinned to achieve a smooth and accentuated outline, a poor blood supply in the thin skin flap may lead to skin necrosis, exposure of the framework, and poor surgical results. Hyperbaric oxygen (HBO2) therapy can promote the healing of complex wounds and flaps. This study sought to determine the effectiveness of HBO2 therapy for the prevention of postoperative complications after framework grafting in microtia reconstruction. Methods We retrospectively evaluated postoperative complications and compared outcomes in pediatric patients who underwent costal cartilage grafting for microtia reconstruction at our institution between 2011 and 2015, according to whether or not they received postoperative HBO2 therapy. HBO2 therapy was applied once daily for a total of 10 sessions starting on the first postoperative day. Results During the study period, eight patients received HBO2 therapy after costal cartilage grafting, and 12 did not. There was no significant difference in the incidence of postoperative ulcers. However, the incidence of framework exposure was lower, and the healing time was shorter in patients who received HBO2 therapy than in those who did not. Discussion HBO2 therapy can be used safely in pediatric patients to reduce postoperative complications and improve the aesthetic outcome of microtia reconstruction. After costal cartilage grafting, HBO2 therapy should be considered as adjuvant therapy.

Abstract
The frequency of cleft lip and palate births in Japan is approximately 0.146%. The study aimed to compare the effects of NAM on restoring nasal morphology and improving extraoral nasal morphology in children with cleft lip and palate in the first stage of treatment using 3D imaging and oral model analysis. The subjects were five infants (37.6 ± 14.4 days old) with unilateral cleft lip and palate. The images taken with the 3D analyzer and oral model used for constructing the NAM at the first examination (baseline) and at the completion of the pre-surgical orthodontic treatment (157.8 ± 37.8 days old) were analyzed. The cleft distance was measured at the upper, middle, and lower points on the 3D images. On the model, the cleft jaw width at the maximum protrusion of the healthy and affected sides of the alveolar bone was measured. After the pre-surgical orthopedic treatment, the measured value on the model decreased significantly by a mean of 8.3 mm from baseline, and the cleft lip width narrowed by an average of 2.8 ± 2.2, 4.3 ± 2.3, and 3.0 ± 2.8 mm at the upper, middle, and lower points of the cleft, respectively. Pre-surgical orthopedic treatment using NAM can help narrow the width of the cleft jaw and lip. The sample size is stated at the study limit in the paper.

Abstract
BACKGROUND AND OBJECTIVES Vascularized lymph node transfer (LNT) is gaining popularity in the treatment of lymphedema. However, it is unclear whether the vascularization of transferred lymph nodes (LNs) contributes to functional improvement. High endothelial venules (HEVs) are specialized vessels that allow lymphocytes to enter LNs. In this study, we compared the numbers of HEVs and lymphocytes in LNs after vascularized and nonvascularized LNT. METHODS Fifty mice were divided into three groups (group 1, pedicled vascularized LNT; group 2, pedicled nonvascularized LNT; group 3, free nonvascularized LNT). Afferent lymphatic reconnection was confirmed by patent blue staining. The transferred LNs were harvested 4 weeks after surgery. HEVs, B-cells, and T-cells were subjected to immunohistochemical staining and quantified. RESULTS Afferent lymphatic reconnection was observed in 13 of 20 transferred LNs in group 1, 11 of 15 in group 2, and 7 of 15 in group 3. The ratio of dilated/total HEVs in transferred LNs with afferent lymphatic reconnection was significantly higher in group 1 than in groups 2 and 3. No significant differences in numbers of B-cells and T-cells were found in the transferred LNs. CONCLUSIONS We found that more functional HEVs were preserved in cases with successful afferent lymphatic reconnection after vascularized LNT than after nonvascularized LNT.

Abstract
PURPOSE Vascularized lymph node transfer is becoming more common in the treatment of lymphedema, but suitable small animal models for research are lacking. Here, we evaluated the feasibility of pedicled vascularized inguinal lymph node transfer in mice. METHODS Twenty-five mice were used in the study. An inguinal lymph node-bearing flap with a vascular pedicle containing the superficial caudal epigastric vessels was transferred into the ipsilateral popliteal fossa after excision of the popliteal lymph node. Indocyanine green (ICG) angiography was used to confirm vascularity of the flap. ICG lymphography was performed to evaluate lymphatic flow at 3 and 4 weeks postoperatively. Patent blue dye was injected into the ipsilateral hind paw to observe staining of the transferred lymph node at 4 weeks postoperatively. All transferred lymph nodes were then harvested and histologically evaluated by hematoxylin and eosin staining. RESULTS In 16 of the 25 mice, ICG lymphography showed reconnection between the transferred lymph node and the afferent lymphatic vessels, as confirmed by patent blue staining. Histologically, these transferred lymph nodes with afferent lymphatic reconnection significantly regressed in size (0.37 ± 0.24 mm2 ) and showed clear follicle formation, whereas those without afferent lymphatic reconnection showed less size regression (1.31 ± 1.17 mm2 ); the cell population was too dense to allow identification of follicles. CONCLUSIONS We established a mouse model of vascularized lymph node transfer with predictable afferent lymphatic reconnection. Both the vascularization and reconnection might be necessary for functional regeneration of the transferred lymph node.

Abstract
AIM Lactate is produced in and released from skeletal muscle cells. Lactate receptor, G-protein-coupled receptor 81 (GPR81), is expressed in skeletal muscle cells. However, a physiological role of extracellular lactate on skeletal muscle is not fully clarified. The purpose of this study was to investigate extracellular lactate-associated morphological changes and intracellular signals in C2C12 skeletal muscle cells. METHODS Mouse myoblast C2C12 cells were differentiated for 5 days to form myotubes. Sodium lactate (lactate) or GPR81 agonist, 3,5-dihydroxybenzoic acid (3,5-DHBA), was administered to the differentiation medium. RESULTS Lactate administration increased the diameter of C2C12 myotubes in a dose-dependent manner. Administration of 3,5-DHBA also increased myotube diameter. Not only lactate but also 3,5-DHBA upregulated the phosphorylation level of mitogen-activated protein kinase kinase 1/2 (MEK1/2), p42/44 extracellular signal-regulated kinase-1/2 (ERK1/2) and p90 ribosomal S6 kinase (p90RSK). MEK inhibitor U0126 depressed the phosphorylation of ERK-p90RSK and increase in myotube diameter induced by lactate. On the other hand, both lactate and 3,5-DHBA failed to induce significant responses in the phosphorylation level of Akt, mammalian target of rapamycin, p70 S6 kinase and protein degradation-related signals. CONCLUSION These observations suggest that lactate-associated increase in the diameter of C2C12 myotubes is induced via activation of GRP81-mediated MEK/ERK pathway. Extracellular lactate might have a positive effect on skeletal muscle size.

Abstract
Malignant melanoma (MM), a well-known skin cancer with a poor prognosis, has various clinical manifestations, but vesiculobullous lesions have seldom been reported. We report a case of MM forming amelanotic vesicles at the site of an in-transit metastasis, and we also review the published reports on vesiculobullous MM. Our patient was an 87-year-old man with a history of a treated plantar MM 2 years previously, who had recurrence of the MM and development of an in-transit metastasis in his lower leg. Histopathological findings revealed vesicles caused by infiltration of the tumour. A review of the English literature revealed nine cases with various clinical presentations of the vesicles or blisters. For patients with MM with vesiculobullous lesions, an accurate medical history and examination of biopsies are of primary importance for management.

In addition, we analyze the ICG assisted integumentectomy and incontinuity techniques and algorithms that we had created when performing this procedure. METHOD In accordance with our algorithm, we performed ICG assisted integumentectomy/incontinuity procedures on 17 patients with stage III melanomas between 2008 and 2016. We also investigated the locoregional recurrence rate in a control group comprising 60 patients at stage III without using the algorithm. RESULTS The former group exhibited a tendency of locoregional recurrence rate suppression. Melanoma cells in the dissected intervening tissue were microscopically identified in 2 out of 17 cases. CONCLUSIONS Our ICG assisted integumentectomy or incontinuity procedures could be effective in controlling locoregional recurrence rates in melanoma cases. Moreover, our method can be generally applied because the dissection is only performed within the lymphatic pathway region identified using indocyanine green.

Abstract
Apert syndrome is a rare craniosynostosis syndrome characterized by irregular craniosynostosis, midface hypoplasia, and syndactyly of the hands and feet. Previous studies analyzed individuals with Apert syndrome and reported some facial and intraoral features caused by severe maxillary hypoplasia. However, these studies were performed by analyzing both individuals who had and those had not received a palate repair surgery, which had a high impact on the maxillary growth and occlusion. To highlight the intrinsic facial and intraoral features of Apert syndrome, five Japanese individuals with Apert syndrome from 5 years and 2 months to 9 years and 10 months without cleft palate were analyzed in this study. A concave profile and a skeletal Class III jaw-base relationship caused by severe maxillary hypoplasia were seen in all patients. The patients exhibited anterior and posterior crossbites possibly due to a small dental arch of Maxilla.

Abstract
OBJECTIVE: To investigate the incidence of unilateral hypodynamic palate (UHP) and velopharyngeal insufficiency (VPI) in hemifacial microsomia (HFM), and to determine the dysmorphic manifestations having significant associations with UHP/VPI in HFM. STUDY DESIGN: This was a nonrandomized study of 48 patients with unilateral HFM without cleft palate. The correlation between each anomaly and UHP/VPI was analyzed statistically. In addition, we observed 4 HFM patients with cleft palate to examine the influence on cleft palate speech. RESULTS: The incidence of UHP in HFM was 50.0% and that of VPI was 14.6%. All the VPI patients had UHP. Severe micrognathia and soft tissue deficiency, macrostomia, and mental retardation were significant risk factors for developing VPI in HFM. Moreover, UHP exacerbated speech in HFM with cleft lip and palate. CONCLUSIONS: Significant correlations were detected between VPI and HFM. This finding should be helpful in the overall management of HFM. © 2007 American Academy of Otolaryngology-Head and Neck Surgery Foundation. All rights reserved.

Abstract
Objective To compare dental arch relationship outcomes following one- and two-stage palatal repair. Design Nonrandomized, clinical trial with concurrent control. Setting Hokkaido University Hospital. Patients Sixty-eight consecutively treated Japanese patients with complete unilateral cleft lip and palate. Interventions Thirty-one of the 68 patients underwent two-stage palatoplasty with delayed hard palate closure, and 37 patients underwent one-stage pushback palatoplasty. Main Outcome Measures Dental casts were taken at 4.9 to 6.3 (mean: 5.2) years of age in the two-stage group and at 4.0 to 6.3 (mean: 5.1) years of age in the one-stage group, and dental arch relationships were assessed using the 5-Year-Olds’ Index (5-Y) by four raters and the Huddart/Bodenham Index (HB) by two raters. Results Intrarater and interrater reliabilities evaluated using weighted kappa statistics were good or better for the 5-Y and HB ratings. The mean 5-Y score was 2.94 in the two-stage group and 3.13 in the one-stage group ( P value was not significant). However, there was a significant difference in distributions between the groups ( P < .05). The HB scores of molars were significantly greater in the two-stage group than in the one-stage group ( P < .05). The rank correlation coefficients between the 5-Y and total HB score (ρ = −0.840, P < .01) and between the 5-Y and the score of the incisors in the HB (ρ = −0.814, P < .01) were significantly increased. Conclusions These results suggest that the anteroposterior relationship was not significantly different between the groups, but the transversal relationship was better in the two-stage group than in the one-stage group.

Abstract
Keloid is an inflammatory and fibrotic disease with an unknown pathogenesis. Regulatory T cells (Tregs) of CD4+ lineage can suppress other effector CD4+ T cells and modulate the immune response. A relative decrease in the number of Tregs may be involved in the pathogenesis of inflammatory and fibrotic diseases. We therefore investigated the number of Tregs in keloids using immunohistochemistry and examined the interaction between Tregs and keloid fibroblasts (KFs) using a coculture system. It was found that the ratio of Tregs/CD4+ T cells was lower compared with that in other common inflammatory skin conditions. In addition, Treg-enriched CD4+ T cells reduced collagen synthesis by KFs. Our findings suggest that a local imbalance of Tregs contributes to the development of keloids and that correction of this imbalance might represent a novel therapeutic approach to keloid fibrosis.

Abstract
Open abdomen management is commonly used for the critically injured patients to avoid abdominal compartment syndrome. But it usually continues for days to weeks and finally results in abdominal wall defect that is too wide to close at once. This article presents an alternative approach to close the giant abdominal wall defect by using the combination of bipedicled flaps with the components separation technique and V.A.C.® system.

Abstract
OBJECTIVE This study was performed to investigate speech outcomes after three different types of palatoplasty for the same cleft type. The objective of this study was to investigate the surgical techniques that are essential for normal speech on the basis of each surgical characteristic. METHODS Thirty-eight consecutive nonsyndromic patients with unilateral complete cleft of the lip, alveolus, and palate were enrolled in this study. Speech outcomes, i.e., nasal emission, velopharyngeal insufficiency, and malarticulation after one-stage pushback (PB), one-stage modified Furlow (MF), or conventional two-stage MF palatoplasty, were evaluated at 4 (before intensive speech therapy) and 8 (after closure of oronasal fistula/unclosed hard palate) years of age. RESULTS Velopharyngeal insufficiency at 4 (and 8) years of age was present in 5.9% (0.0%), 0.0% (0.0%), and 10.0% (10.0%) of patients who underwent one-stage PB, one-stage MF, or two-stage MF palatoplasty, respectively. No significant differences in velopharyngeal function were found among these three groups at 4 and 8 years of age. Malarticulation at 4 years of age was found in 35.3%, 10.0%, and 63.6% of patients who underwent one-stage PB, one-stage MF, and two-stage MF palatoplasty, respectively. Malarticulation at 4 years of age was significantly related to the presence of a fistula/unclosed hard palate (P<0.01). One-stage MF palatoplasty that was not associated with postoperative oronasal fistula (ONF) showed significantly better results than two-stage MF (P<0.01). Although the incidences of malarticulation at 8 years of age were decreased in each group compared to at 4 years of age, the incidence was still high in patients treated with two-stage MF (45.5%). On the whole, there was a significant correlation between ONF/unclosed hard palate at 4 years of age and malarticulation at 8 years of age (P<0.05). CONCLUSION Appropriate muscle sling formation can compensate for a lack of retropositioning of the palate for adequate velopharyngeal closure. Early closure of the whole palate and the absence of a palatal fistula were confirmed to be essential for normal speech. To avoid fistula formation, multilayer repair of the whole palate may be critical.

Abstract
Tessier cleft types 3 and 4 are both rare craniofacial anomalies. Here we present the first case of a girl born with a combined anomaly of Tessier clefts 3 and 4 with severe bilateral cleft lip, a displaced premaxilla, and three-dimensional underdevelopment of the hard and soft tissues of the maxilla and zygoma. This type of rare facial cleft poses a major operative challenge. Over a period of years, presurgical alveolar molding with an active appliance was followed by seven operations. A satisfactory esthetic outcome was obtained. A multidisciplinary approach to treatment with a plastic surgeon in charge of the operations and an orthodontist in charge of the cleft deformity is essential.

Abstract
BACKGROUND The objective of this study is to evaluate the lymph drainage from the primary focus to the regional lymph nodes in patients with melanomas of the upper extremity and upper trunk region. METHOD The study is a retrospective study of 20 patients with upper extremity melanomas and 14 patients with upper trunk melanomas treated with axillary lymph node dissection (ALND) or sentinel lymph node biopsy at the hospital. ALND was performed in 14 cases. In these cases, 12 were curative dissections and 2 were elective dissections. The dominant lymph drainage patterns from the primary regions were analyzed. RESULTS Among the upper extremity and upper trunk region melanomas, lymph drainage to Level I was determined in all cases. In these two regions there were no cases of lymph drainage to Level II not passing through Level I. Furthermore, there were no cases where sentinel lymph node or metastasis of the lymph nodes was clearly determined in Level III. Among the upper extremity melanomas, lymph drainages to the cubital (10 %) and mid-arm nodes (5 %) were established. Among the scapular region melanomas, lymph drainages to the supraclavicular nodes (25 %) were determined. CONCLUSIONS There was a dominant lymph drainage pattern of melanomas of the upper extremity and upper trunk region to Level I. No lymph node dissection of Level III in patients with melanomas of the upper extremity and upper trunk region is necessary unless preoperative examination determines a high possibility of metastasis-positive lymph nodes in level III.

Abstract
We report a new simple method of cranial reconstruction using an autologous split calvarial bone, combined with free graft of temporal loose areolar tissue. A 58-year-old woman suffered from a cranium defect on her left side. The originating bone infection happened after initial brain tumor surgery. Part of the left side of her scalp just above the damaged cranial area had become very thin due to previous cranioplasty, which involved a titanium mesh plate and postoperative infections. We performed a cranial reconstruction with an autologous split calvarial bone, combined with loose areolar tissue free graft, for the damaged area with skin from the inner side. In our case, we expect that the addition of the free graft of loose areolar tissue to the autologous calvarial bone graft will effectively contribute to the skin's healing and provide good cosmetic results in our short follow-up period. A free graft of loose areolar tissue for the damaged skin area may be a new optional method for cranial reconstruction in a patient with skin trouble.

Abstract
Objective : To assess the congenital and postnatal factors that affect degree of malocclusion in patients with unilateral cleft lip and palate using multivariate statistical analysis. Design : Retrospective study. Patients : All information on 135 subjects with unilateral cleft lip and palate was obtained from an oral examination and radiograph at the initial examination at an orthodontic clinic and from surgical records. Plaster models were taken before orthodontic treatment. The ages of the subjects ranged from 5 to 8 years with a mean age of 6.9 years. All primary surgeries for the patients were performed at a university hospital. Main Outcome Measures : The GOSLON Yardstick was used to assess the dental arch relationships (degree of malocclusion) in patients. Family history of Class III, degree of cleft, and congenitally missing upper lateral incisor on the cleft side were chosen as congenital factors inducing malocclusion. Presurgical orthopedic treatment, cheiloplasty, and palatoplasty were chosen as postnatal factors. Associations between various factors and dental arch relationships were assessed using logistic regression analysis. Results : According to adjusted odds ratios, family history of Class III is associated with a significantly worse dental arch relationship. Palatoplasty using push-back alone correlated to a dental arch relationship that was significantly worse than palatoplasty using push-back with a buccal flap. Conclusions : Multivariate analysis shows evidence that a positive family history of Class III and palatoplasty using push-back alone are associated with worse malocclusion of unilateral cleft lip and palate patients.

Abstract
BACKGROUND Published reports indicate that corticosteroid injections can prevent recurrence after keloid excision, but the side effects of repetitive intralesional steroid injections may preclude treatment maintenance. Additionally, few of these studies employed a standardized treatment protocol. OBJECTIVES To analyze the results of a new uniform treatment protocol combining corticosteroid injections and ointment application designed to reduce recurrence rates after excisional surgery in individuals with keloids or hypertrophic scars. METHODS As a standard procedure, the first corticosteroid injection took place after removal of the sutures and then once every 2 weeks after that until it had been done five times. In addition, all postsurgical wounds received self-administered steroid ointment application twice daily for 6 months after suture removal. RESULTS Postoperative follow-up in this series ranged from 24 to 57 months (median 32 months, mean 32.5 months). Recurrence occurred in three of the 21 keloid cases (14.3%) and one of the six hypertrophic scar cases (16.7%). CONCLUSION We evaluated a new standardized adjuvant corticosteroid therapy to prevent recurrence after surgical keloid or hypertrophic scar excision. Using this method, we achieved low recurrence rates.

Abstract
We report a case of cranial reconstruction using autologous split calvarial bone combined with calcium phosphate bone cement (CPC). A 19-years-old man suffered from cranium defect and rhinorrhea originating from frontal skull base fracture in a traffic accident. After CSF hydration treatment had finished, continuously we performed cranial reconstruction with autologous split calvarial bone so that the patient could return to work at an early stage. The use of autologous split calvarial bone with CPC was able to increase stability of the construct and provide excellent cosmetic result in our short follow up period. The combination use of these two materials may be useful for cranial reconstruction in patients with cranium defect.

Abstract
Ethanol is a commonly used sclerosant for lymphatic malformation (LM), and recent evidence has shown that macrocystic LMs respond very well to percutaneous sclerotherapy. However, the volume of absolute ethanol that can be injected safely is small (0.5-1 ml/kg), and that is the reason it is often ineffective in extensive LM. We report two cases of giant LM with occasional high fever and pain or abnormal gait. To overcome dose limitation and to prevent systematic toxicities, we performed both injection of absolute ethanol and aspiration of it after 5 min exposure to LM. The injected maximum ethanol dose per one session is 70-260 ml and no systemic complication occurred. The 1-3 sessions of those procedures reduced the frequency of high fever and improved the swelling of those lesions. The injection and aspiration technique maximises the efficacy of sclerotherapy for extensive macrocystic LM in adults.

Abstract
Soft tissue sarcomas of the head and neck region are rare, and very little has been described about the reconstructive methods used after sarcoma resection of cheek soft tissue sarcomas. Reconstructive methods for cheek defects after sarcoma resection are presented and the possibilities, advantages, disadvantages, and expected results are described. A series of 3 patients with cheek soft tissue sarcomas were examined. Reconstructive methods included; one skin graft, a free forearm flap and a cervicofacial flap. All patients had lesions < 5 cm and low-grade tumours, and no case presented local recurrence or metastases. The choice of reconstructive methods depends mostly on the complexity of the defect. In cases comprising comparatively small or minor defects, reconstructions using local flaps, such as the cervicofacial flap, provide better aesthetic and functional results than either free flaps or skin graft.

Abstract
Our modification of the Nuss procedure includes insertion of both the introducer and the thoracoscope through the same skin incision, which enables continuous visualisation of the tip of the introducer during blunt dissection across the mediastinum. From January 2001 to January 2005 we studied 32 consecutive patients whose ages ranged from 3 to 30 years. They had all undergone the modified procedure. The mean operating time was 1 hour 44 minutes (range 43 minutes-4 hours 20 minutes). Blood loss was less than 10 ml. There were no intraoperative bleed complications. The modification that we devised may minimise the risk of cardiothoracic and vascular injuries and the procedure is safe.

Abstract
Melanoma has a high tendency to metastasize to lymph nodes, which is one of the clinicopathological factors to indicate poor prognosis. Recent investigations have shown the importance of lymphangiogenesis in lymph node metastasis in a variety of human tumors including melanoma. However, molecular mechanism of lymphatic metastasis is still poorly defined. We examined influence of interactions between normal lymphatic endothelial cells (LECs) and melanoma cells on cell migration. Medium conditioned with LEC (LEC-CM) contained chemotactic and chemokinetic activities for human melanoma cell lines. The chemotactic activity was fractionated in more than 100 kDa, and inactivated by heat-treatment. The chemotactic activity of LEC-CM was abolished by immunodepletion with anti-laminin-1 antibody. And immunoprecipitation and Western blot analyses revealed that LEC-CM contained laminin-421. When melanoma C8161 cells were treated with function-blocking antibodies to integrin alpha3 or alpha6, their chemotactic responses to LEC-CM were markedly reduced. Furthermore, the knock-down of tetraspanin CD151 weakened the chemotactic responses of C8161 and MeWo cells to LEC-CM. These data suggest that laminin-421 secreted by LEC possibly facilitates lymphatic metastasis through the induction of chemotaxis of melanoma cells.

Abstract
Lipomas are benign tumors and, therefore, a surgical technique that does not leave a visible scar would be an ideal method. A forehead lipoma can be extracted using a small remote incision with endoscopic assistance for aesthetic purposes. However, endoscope-assisted surgery is usually technically demanding, time-consuming, and less cost-effective. In this report, we propose an alternative approach to the surgical resection of a forehead lipoma with a small remote incision. Our method uses a surgical raspatory. Our technique allows the complete removal of the lipoma with no complications using a raspatory passed down a subcutaneous tunnel from an incision placed in an aesthetically advantageous site.
