Rhinoplasty Appliance System
RAS, or Rhinoplasty Appliance System, refers to a presurgical orthopedic molding device used in orthodontics, specifically for infants with cleft lip and palate. It's designed to improve nasal symmetry and reshape the nasolabial region before surgery. The system includes a nasal prosthesis with stents, protective pads, and adhesive tapes to apply orthopedic forces.
RAS and Cleft Lip and Palate:
Purpose:
The RAS appliance aims to correct nasal asymmetry and reshape the nose in infants with cleft lip and palate.
Components:
The system comprises nasal stents, protective pads, and adhesive tapes.
Function:
The stents are placed in the nostrils to straighten the septum and elevate the lateral alar cartilage on the affected side.
Benefits:
The appliance helps improve both functional and aesthetic outcomes by harmonizing the nasal features.
How it works:
The nasal prosthesis, consisting of intranasal extensions (stents) and columellar support, is inserted into the nostrils.
Lateral arms with hooks are attached to the prosthesis.
Protective pads are placed to prevent skin irritation from the adhesive tapes.
Adhesive tapes are used to secure the appliance and apply the necessary orthopedic forces.
In summary, the RAS appliance is a specialized orthodontic tool used in the pre-surgical management of cleft lip and palate to improve nasal symmetry and function before surgical intervention.
