Komprese horní čeíisti je problémem, se kterým se setkáváme ve stomatologických ordinacích velmi často. Technika rychlé expanze pátraje efektivní metodou často používanou u rostoucích pacientů. U dospělých jsou navíc nutné speciální osteotomie na přilehlém skeletu. V literatuře jsou navrženy rozdílné kombinace osteotomií. Autoři uvádějí dva případy chirurgicky asistované rychlé expanze patra, které byly provedeny rozlišným způsobem. Dosavadní zkušenosti ukazují, že metoda chirurgicky asistované RPE je účinná a autoři ji doporučují.
The narrow maxilla is an frequent condition in our surgeries. The technique of rapid maxillary expansion presents an effective measure used frequently in growing cWWren-Grown-oppatients need special osteotomies in neighbouring bones. Various combinations of osteotomies were published. Authors present two patients with the surgically assisted rapid maxillary expansion, made in different way in each of them. The experience shows that the method is effective and is proposed for the use.

Sarcomas in the head and neck area are rare diseases with an incidence of under 1% of all head and neck malignant tumours. Osteosarcomas or osteogenic sarcomas consist of neoplastic cells that produce osteoid bone or immature bone. Sarcomas develop more in the mandible than the maxilla. The exact diagnosis of different types of sarcomas is based on the immunohistochemical investigation. These rare tumours are of mesenchymal origin; osteosarcomas and chondrosarcomas are the most common types-Ewing's sarcomas. The use of proton beam radiotherapy in the treatment of osteosarcoma of the maxilla is rarely reported in the literature. We present a case of successfully treated (surgery and proton beam radiotherapy) poorly differentiated highly aggressive osteosarcoma in the ethmoids and maxillary sinus and morbidity after the treatment. We were presented with a case of a 65-year-old man with anaesthesia and palsy of the right face. The stomatology department performed the extraction of a tooth. One month later, the wound was still open. The histology showed an osteogenic sarcoma in the area of the wound. The oncologist and maxillofacial surgeons in a catchment hospital recommended a nonsurgical approach. Hence, we performed a radical maxillectomy and ethmoidectomy, after which we continued with proton bean radiotherapy. The patient is now five years after therapy without signs of sarcoma; however, he has blindness in the right eye and reduced vision in the left eye, as well as gliosis of the brain, vertigo, tinnitus, trismus, and ancylostomiases. Head and neck osteosarcomas treatment is considered a complex multidisciplinary task. It is currently argued that there is no clear therapeutic protocol for successful treatment. Innovations in treatment modalities such as proton beam radiotherapy appear to have potential, although their effects on long-term morbidity and survival outcomes are still undetermined. We present a rare case report of an osteosarcoma of the maxilla involving an innovative, successful treatment procedure combining surgical excision followed by proton beam radiotherapy. This treatment approach may enable maximum tumour control. This protocol has not been adequately described in the world literature for this diagnosis.
