The most important craniofacial dysostosis & syndromes are Crouzon, Apret, Pfeiffer.Carpenter Saether- Chotzen. The common characteristic is premature closure of cranial sutures, which result in Maxillofacial deformities. Perfect recognition and carefully evaluation are the most important points in their reconstruction surgery.Because the prevalence & surgical treatment of Crouzon syndrome is low, I present a case report include surgical treatment of a patient with crouzon which was a accomplished in Shariati Hospital.

Distraction osteogenesis (DO), firstly introduced to the medical world by Russian scientist Ilizarov for long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of maxillofacial deformities. Natural events occuring during the repair of a fractured bone segment not only lead to the desired bone length but also prevent from the undesired disadvantages of osteotomies and bone grafting. Recently a lot of investigations have been conducted to evaluate the efficacy of DO in the treatment of maxillofacial deformities, which in some cases have lead to successful results. In the present article a lot of issues in maxillofacial surgery and different treatment goals associated with DO are discussed.

Background and Aims: Nasal obstruction is a common condition among children, in which delaying treatment can stabilize its negative effects on dentoalveolar structures during adulthood. In this study we aimed to investigate the effect of total nasal obstruction on the craniofacial structures of rabbits.
Materials and Methods: In this animal study, total numbers of 44 rabbits with high genetic proximity were selected. Several metal implants were inserted in the anatomic landmarks of their skulls and then underwent three different types of x-ray exposure (lateral, posterior-anterior and occlusal views). Half of them underwent surgically assisted total nasal obstruction, and the other half were considered as control group. All rabbits were kept in the same environment up to maturation period. Then, they underwent the same x-ray exposures. The primary and final radiographs were traced and various linear and angular were compared between them.
Results: The anterior facial height (P=0.01), maxillary depth (P=0.005), articular angle (P=0.005), maxillary and mandibular plan angle were significantly more in the rabbits with total nasal obstruction. However, the interdental width (P=0.005), maxillary perimeter (P=0.005), nasopharyngeal width (P=0.01) and maxillary and mandibular width were significantly less in them. The skull base length (P=0.30), gonial angle (P=0.40), and maxillary length (P=0.10) were not significantly different between the two groups.
Conclusion: Total nasal obstruction had various impacts on the craniofacial structures.
