RESUMO
INTRODUCTION: Cleft palate requires surgery in the first years of life, furthermore repairing anatomically the soft and hard palate is complex on a surgical level because of the fine tissues and the local intraoral configuration. It is valuable to train first on simulators before going to the operating room. However, there is no material dedicated to learning how to perform intraoral sutures in cleft palate surgery. We made one, in an artisanal manner, in order to practice before the real surgical gesture. BUILDING THE SIMULATOR: The simulator was designed based on precise anatomical data. A steel pipe, fixed on a rigid base represented the oral cavity. An adapted split spoon represented the palate. All pieces could be removed in order to apply a hydrocellular dressing before training for sutures. USE OF THE SIMULATOR: Our simulator was tested by 3 senior surgeons in our department in close to real-life conditions in order to evaluate its anatomical accuracy. CONCLUSION: It is valuable to have a simulator to train on cleft palate sutures within teaching university hospitals that manage this pathology. Our simulator has a very low cost, it is easy to make and is anatomically accurate.

INTRODUCTION: Lacrimal cysts are rarely described and must be differentiated from diseases of the lacrimal gland. We present a rare case of lacrimal cyst developed from an accessory lacrimal gland. CASE REPORT: The management consisted of excision using a tarsoconjonctivale approach. DISCUSSION: Most cysts are diagnosed from the third decade, manifested by progressive exophthalmos. It is a benign disease. However, the differential diagnosis with malignancy is not excluded. Surgical resection is desirable if tumors become symptomatic.

Rhinophyma, final stage of rosacea is considered as benign pathology. We present the case of a patient with basal cell carcinoma diagnosed on rhinophyma. The removal of all cutaneous nasal unit and its analysis has diagnosed the presence of three basal cell carcinomas and two in situ squamous cell carcinomas. Reconstruction was performed by full-thickness skin graft. The literature reports a few cases of association between rhinophyma and skin cancers but none ever reported the simultaneous presence of basal cell carcinoma and squamous cell carcinomas. The low number of articles does not reveal statistically significant relationship between rhinophyma and skin cancer, which would consider the rhinophyma as a risk factor. Monitoring of these patients should be as rigorous as possible and surgical care requires histologic analysis not to omit the presence of cancerous lesions.

Dermatofibrosarcoma protuberans is a malignant and locally invasive tumor. It generally affects young adults. However, in rare but not exceptional cases, children can suffer from this disease. In the literature, there are only few studies on this pathology occurring in children. The main treatment is surgical excision with large margins. We studied in our series 15 cases of dermatofibrosarcoma in children between 1995 and 2008. The data were retrospectively collected. The aim of our study is to underline the best support for this pathology in children. The mean age at the moment of diagnosis was 13 years old. None of our patients underwent surgery for dermatofibrosarcoma removal before. The diagnosis was confirmed by biopsy and immunology by FISH method. In 60% of the cases, the lesion, which is very polymorphic, was on the trunk. In three cases, a skin trauma was noted in the patient's history. Surgical management consisted in tumor's excision with a 3 cm margin laterally associated with the removal of the first unaffected anatomical layer in depth. Reconstruction was adapted to the defect's width, depth and topography. The mean follow-up was 7.8 years. There were no relapses reported in a 3-year period at least. Complications were two scars dehiscences which needed skin graft for repair and a scarring alopecia reconstructed secondarily by a skin expansion protocol. No functional sequelae were reported in our series. As dermatofibrosarcoma in children presents the same clinical aspect and evolution as in adults, we treated it the same way. This diagnosis should not be ignored in children, and should be made early to give the patient the most effective support.

To master the skills needed for microsurgery techniques, residents must enrol in a long and complex training program that includes manipulations on simulators, on ex vivo tissues and finally in vivo training. This final step consists of performing vascular anastomoses on murine models. We propose here a simulation program designed to decrease the number of rats used during the final in vivo training. Our study presents the materials used, the various exercises proposed and their evaluations. Two identical student groups were compared in the framework of the University Diploma of Microsurgery. Group A (seven students) followed a classic training program, all of whom achieved permeable vascular anastomoses. A total of 149 rats were needed for this group. Group B (seven students) first validated their manipulations on the task-trainer simulation program. A mean of 6 h was necessary to obtain this validation. All these students achieved the required permeable vascular anastomoses but only 77 rats were used for this group. This simulation program spared 72 rats, abiding by the Russell and Burch concept of a humane experimental technique, namely the 3R principles. This home-made, cost-efficient and easy-to-use task trainer included various exercises with increasing difficulty levels and a progressive scoring system. We believe that microsurgery training needs to include both simple and sophisticated tools in order to reduce the number of animals used to master these surgical skills.
