Relationship between chronic nasal obstruction and craniofacial growth: an experimental model

Relationship between chronic nasal obstruction and craniofacial growth.

The aim of this paper was to verify if the growth of the nasomaxillary complex can be influenced by a purely functional alteration such as nasal obstruction, which was induced experimentally in a genetically controlled animal model. Sixty albino rats were employed. Twenty of them had the right nostril occluded by a synthetic resin; another twenty had both nostrils occluded; the other 20 were ta...

The relationship between nasal obstruction and craniofacial growth.

The relationship between nasal obstruction and craniofacial growth is unclear. The literature indicates that upper-airway compromise produces chronic mouth breathing, especially in the dolichocephalic (narrow-faced) child. It has been shown that a greater tendency exists toward the skeletal pattern associated with long face syndrome in dolichocephalic head types. Therefore, it becomes difficult...

an investigation about the relationship between insurance lines and economic growth; the case study of iran

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...

The effect of total nasal obstruction on the anatomy of craniofacial structures: An animal study

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 ...
