Every patient is unique. Your anatomy determines the extent of surgery required. If you have difficulty breathing with an anatomic deviation of your nasal septum, that is corrected first. Subsequently, the external features are refined. The length of your nose, width of the base, shape of the tip, rotation of the tip are common areas of concern. Typically, an experienced Rhinoplasty Surgeon performs a Septorhinoplasty in 2-3 hours.
It is difficult to tell you how long it may take to complete a rhinoplasty without having an evaluation or photographs. A procedure may take anywhere from 1-4 hours depending on what needs to be done.
