OBJECTIVE Thyroid surgery is common and complications are not rare. High-intensity focused ultrasound (HIFU) could be a possible minimally invasive alternative to surgery. The aim of this study was to assess the feasibility of using HIFU to obtain localized ablation of thyroid tissue without affecting neighboring structures. METHODS The ewe was chosen as(More)
Alveolar soft-part sarcoma is a rare malignant tumour of uncertain histogenesis, the two main sites of which are the lower extremities in adults and the head and neck in children. We know of only three case reports of intraoral locations without tongue involvement. Here, we describe the first case of an alveolar soft-part sarcoma of the cheek which(More)
BACKGROUND Thyroid surgery is common, but complications may occur. High-intensity focused ultrasound (HIFU) is a minimally invasive alternative to surgery. We hypothesized that an optimized HIFU device could be safe and effective for ablating benign thyroid nodules without affecting neighboring structures. METHODS In this open, single-center feasibility(More)
HIFU is used in the treatment of cancer (prostate, breast) and uterine fibroma but not yet in TNs. This case report describes the first successful ablation of a toxic TN with HIFU. TSH and radioiodine scan normalization were achieved without complications and maintained for 18 months. HIFU treatment is a minimally invasive technique that may be an effective(More)
BACKGROUND Although thyroid nodules are frequently detected in patients during routine examinations, such nodules are rarely malignant. Surgical treatment of nodules is controversial because of the possible complications associated with surgery, and there is an unmet need for a minimally invasive alternative. We previously reported on a high-intensity(More)
The contribution of the segmental osteotomies in the ortho-surgical protocols is no longer to demonstrate and found a new lease of life thanks to the combination with the bone distraction techniques. The osteotomy of Köle, initially described to close infraclusies, and then used to level very marked curves of Spee has more recently been used to correct(More)
