It is best to share a photograph with respect to keeping your privacy a priority. Everyone has some vagaries of asymmetry in their face and nose. If the nostril gives a snearing appearance because it is tilted and retracted to one side, or simply has an oval versus a round shape, this is important to discuss. Plastic Surgery of the Nose, the most difficult procedure of the face we perform, can yield stunning results when a proper diagnosis and the appropriate principles of operation are selected.
Open Rhinoplasty would not be necessary per se, but some doctors feel more comfortable with an open approach. Many of us still perform Endonasal surgery for the nose with no columellar scar, since our training and experience permits us to address all problems from the inside. The complexities of Rhinoplasty has prompted many training programs to introduce this method for those acquiring initial experience, and in practice those, surgeons seeing an array of complex nasal deformities will deploy it.
Retracted nostrils related to a deficiency of skin and cartilage may be simply treated with grafting from an ear to restore fullness. This would leave a fading scar on the inside roof of the nostril. A fading scar behind the ear is all that is required for the graft site.
