Micrognathia is characterized by a small and retrusive mandible. It reduces mouth floor size, determines a retruded position of the tongue. This causes a reduced airflow in the hypopharinx. Micrognathy is related to an altered pulmonary function in OSAS patients who, passing from erect posture to supine one, have some changes that emphasize this disturb: soft palate is shortened and thickened, the tongue reduces its length and falls backwards. As a consequence, available airspace is reduced. Data are derived from morphometric three-dimensional analysis of CT images after 3D reconstruction of the jaw, airways. Pulmonary function, analysis of anatomic structures are evaluated through clinical, instrumental and cephalometric studies. Aim of this project is to analyze and compare mandibular morphology and alterations of pulmonary physiology in micrognatic patients and healthy patients to classify the severity of upper airway obstruction and to propose appropriate treatment measures.
