There is herein described an orthonostric device in the form of a nasal stent for insertion in the nostril of a patient for the correction of abnormalities and stenosis of the nostril. The stent is formed so that it can be expanded or contracted laterally by means of a tool which permits adjustment without the removal of the stent. A wire retaining clip is affixed to the stent and extends about the alar crease of the nose for retention of the stent. A method of forming the stent is also described which involves taking a casting of the patient's nostril, forming a mold and placing a resin liquid mix therein. Before setting of the resin, a separator or divider is inserted in the mold to separate the stent into two halves which are joined by a jack screw at the proximal end to permit adjustment by means of the tool.
