Revision Rhinoplasty FAQs
Q - What is revision rhinoplasty? Q - Who is a good candidate for revision rhinoplasty? Q - Where is the revision rhinoplasty procedure performed? Q - What type of anesthesia is used for revision rhinoplasty? Q - How is revision rhinoplasty performed? The closed technique can be used in some cases of revision rhinoplasty where additional selective reduction of the bone and/or cartilage is indicated. It can also be used in cases where the bridge requires augmentation due to over-reduction during prior surgery. Unfortunately, revision rhinoplasty of the tip using the closed technique is significantly more challenging because of excessive scar tissue in this region. In most cases of revision rhinoplasty, an open technique is utilized because of the more complete and direct exposure that is afforded using this approach. The following summarizes the most common techniques used in revision rhinoplasty for the most frequently seen deformities: In many cases of revision rhinoplasty, the nasal bones (bony vault) have not been narrowed and/or aligned properly. In these cases, the bones require further narrowing to achieve a more refined appearance on the frontal view. If the bones are still improperly aligned (crooked), the vault requires additional mobilization to achieve a more symmetric frontal view alignment. Middle vault (the middle one-third of the nose) collapse is a commonly seen deformity following prior rhinoplasty which usually results from an over-aggressive reduction (lowering) of the bridge and subsequent separation and collapse of the cartilage. This appears nine to twelve months later as a visible inverted V deformity on the frontal view of the bridge (below the nasal bones) and also manifests as breathing difficulty on one or both sides of the nose due to a compromise of the internal valve of the nose (one of the most critical cross sectional areas of the nose when it comes to breathing). Techniques to repair a collapsed middle vault usually involve the placement of spreader grafts which are hidden grafts made of the patient’s own cartilage. If there is sufficient septal cartilage remaining, the spreader grafts can be fashioned from this material. If there is insufficient septal cartilage remaining, which is often the case, ear (auricular) cartilage can be used as a substitute. Spreader grafts are placed parallel with the bridge in between the upper lateral cartilage and the dorsal septal margin. This helps to widen the middle vault and reinforce the structural integrity of the bridge across this region. If the nose requires augmentation (addition) for a bridge that was excessively lowered during prior rhinoplasty, cartilage grafting is the first choice and this includes using either septal cartilage, ear cartilage or rib (costal) cartilage grafting. Rib cartilage grafting is usually reserved for those cases of revision rhinoplasty where there is at least a moderate amount of loss in bridge height. In many cases of revision rhinoplasty, the support of the tip has been comprised due to improper technique used during prior surgery. If this involves a compromised septum and tip junction, it can result in a tip that is insufficiently projected, or under projected. In these cases, cartilage grafting is often required in the form of a strut graft (columellar strut graft) which is sutured to the edge of the septum to restore proper tip support. The actual tip is then reshaped with the use of a shield-shaped tip graft that is sewn over the native cartilage to help redefine the tip. In other cases, the tip support has been compromised as a result of excessive removal of the actual tip cartilage. This usually involves excess removal of the cephalic (upper) margin of the tip cartilage which can result in a tip that scars upward excessively and leads to over rotation, often referred to as a pig nose deformity or a short nose. Revision rhinoplasty techniques to repair this deformity involve the use of cartilage grafts to counter-rotate the tip back down to a more natural position. In other cases, excess removal of the tip cartilage can lead to a weakening of the nostril side walls. This manifests as unwanted pinching of the nasal tip and also requires reinforcing cartilage strut grafts to restore a more natural convex tip contour. In many revision rhinoplasty cases, the skin is notably thin, due in part to incorrect elevation of the tissue planes during prior surgery. In other cases, contour irregularities along the bridge have resulted from prior surgery and easily show through a thin skin layer. In these cases, temporal fascia grafting is frequently used to thicken the overlying nose skin to minimize the chances of visualizing minor contour irregularities during the healing process. Temporal fascia harvesting uses a hidden incision within the hair-bearing scalp (without shaving the hair) and this incision heals relatively quickly. Once the nose has been reshaped, the fascia is placed over the bone and cartilage framework and below the skin. This provides an additional ‘cushion’ layer that helps the nose to look smoother and more natural as it heals. Fascia grafting is usually not required during revision rhinoplasty for patients with thicker skin. After achieving the desired changes, the incisions are closed with meticulous technique. To minimize soft tissue swelling, the nasal skin is taped. An external nasal cast will be placed for additional stabilization in cases where the nasal bones have been reshaped.
