Nasal cavity changes and the respiratory standard after maxillary expansion

Nasal cavity changes and the respiratory standard after maxillary expansion.

UNLABELLED Mandibular cross-sectional deficiency is a dentofacial defect in connection with the narrowing of the mandibular arch width. This abnormality is a significant etiopathogenic factor and it is often associated with nasal breathing difficulties. This atresia may be treated through Rapid Maxillary Expansion or Surgically Assisted Rapid Maxillary Expansion, depending on the patient's age....

Changes in nasal air flow and school grades after rapid maxillary expansion in oral breathing children

OBJECTIVE To analyse the changes in nasal air flow and school grades after rapid maxillary expansion (RME) in oral breathing children with maxillary constriction. MATERIAL AND METHODS Forty-four oral breathing children (mean age 10.57 y) underwent orthodontic RME with a Hyrax screw. Forty-four age-matched children (mean age 10.64 y) with nasal physiological breathing and adequate transverse m...

The reduction of nasal airway resistance by rapid maxillary expansion and its effect on respiratory disease.

Maxillary protraction after surgically assisted maxillary expansion

This case report describes the orthodontic treatment of a 32-year-old woman with a Class III malocclusion, whose chief compliant was her dentofacial esthetics. The pretreatment lateral cephalometric tracings showed the presence of a Class III dentoskeletal malocclusion with components of maxillary deficiency. After discussion with the patient, the treatment option included surgically assisted r...

Changes in soft tissue nasal widths associated with rapid maxillary expansion in prepubertal and postpubertal subjects.

OBJECTIVE To evaluate changes in the soft tissue width of the nose induced by rapid maxillary expansion (RME). Data on greater alar cartilage (GAC) and alar base (AB) widths were compared with a normative sample within the same age range. MATERIALS AND METHODS This prospective study consisted of an RME sample of 79 patients treated with an RME protocol. Mean age at the start of RME treatment ...
