Preservation Rhinoplasty Dr. Buonassisi's Specialty Explained

Preservation rhinoplasty keeps the native cartilage and bone structure intact rather than removing and rebuilding it. The result is a more natural look, faster recovery, and a lower revision rate. Here’s how it works.

Facial Plastic Surgeon

Dr. Buonassisi focuses exclusively on the face and has performed thousands of rhinoplasty procedures. His approach emphasizes natural results, patient education, and careful pre-operative planning.

<p>For most of the history of rhinoplasty, the standard approach involved removing cartilage and bone to reshape the nose. The logic was straightforward: if a structure is too large or too prominent, take some away. Preservation rhinoplasty challenges that assumption at its foundation. Rather than excising the structures that give the nose its shape, preservation technique repositions and redrapes them — keeping the anatomy intact and working with it instead of against it.</p> <p>The technique is not new in principle. Surgeons were describing structure-conserving approaches as far back as the 1990s, but it was largely set aside as reductive methods became dominant. Over the past decade, a rigorous body of surgical literature — led by researchers including Saban, Gerbault, and Daniel — has formalised the approach, refined the instrumentation, and established the anatomical criteria that make a patient a good candidate. Dr. Buonassisi trained extensively in these methods and has integrated preservation rhinoplasty as a core technique at 8 West Clinic.</p> <blockquote>"The best rhinoplasty is the one that no one can tell you had. Preservation technique gives us the best chance of achieving that — because we are working with the nose's own architecture, not replacing it."</blockquote> <h2>What preservation rhinoplasty actually means</h2> <p>The term is used loosely in marketing, which creates confusion. In precise surgical terms, preservation rhinoplasty refers to a specific set of manoeuvres that avoid the conventional dorsal hump reduction approach — where the upper lateral cartilages and nasal bones are cut, removed, and then narrowed with osteotomies. Instead, the dorsum is lowered by releasing the osseocartilaginous framework from its underlying attachments and allowing it to descend as a single, intact unit.</p> <p>The ligamentous connections between the skin and the underlying cartilage are preserved wherever possible. The result is a nose that retains its natural tissue relationships, its native skin draping, and its structural integrity.</p> <p>This is distinct from simply being conservative with tissue removal. A surgeon can be cautious with a conventional reductive approach and still not be performing preservation rhinoplasty. The distinction lies in the surgical architecture: preservation technique requires a specific understanding of the scroll ligament, the keystone area, and the osseocartilaginous junction — and a deliberate decision to maintain those structures rather than disrupt them.</p> <p><strong>Preservation rhinoplasty is not simply a conservative approach to conventional rhinoplasty.</strong> It is a fundamentally different surgical architecture — one that repositions the dorsal framework as a unit rather than excising components of it. The difference matters for recovery, long-term results, and revision risk.</p> <h2>How the dorsum is lowered without removing it</h2> <p>The most common reason patients seek rhinoplasty is a dorsal hump — the bump visible on the bridge of the nose in profile. In conventional rhinoplasty, this is addressed by removing the excess cartilage and bone, then performing osteotomies to close the resulting open roof. This approach is effective, but it disrupts the structural continuity of the dorsum and requires the body to heal a significant amount of altered tissue.</p> <p>In preservation rhinoplasty, the hump is addressed through one of two primary methods. The <strong>let-down technique</strong> shortens the septum at its base, allowing the entire osseocartilaginous dorsum to descend. The <strong>push-down technique</strong> releases the nasal bones from their periosteal attachments and compresses the dorsum inferiorly. Both approaches lower the dorsal profile while keeping the cartilage and bone intact as a continuous structure.</p> <p>The practical implication is that the dorsum heals as a unit. There is no open roof to close, no resected cartilage to replace, and no disruption to the internal valve architecture that determines how well the nose breathes. Swelling resolves more predictably, and the final result tends to emerge earlier in the recovery period.</p> <h2>The anatomy that makes preservation possible</h2> <p>Not every nose is a candidate for preservation technique. The approach depends on specific anatomical conditions, and Dr. Buonassisi assesses each of these carefully before recommending it.</p> <p><strong>Skin thickness</strong> is the first consideration. Preservation rhinoplasty works best in patients with medium to thin skin. Thick skin can mask the refined result and may not drape as predictably over a repositioned framework. In these cases, a hybrid approach or conventional technique may produce a more controlled outcome.</p> <p><strong>Cartilage strength</strong> is the second factor. The preservation approach relies on the cartilaginous framework being resilient enough to hold its new position after repositioning. Weak or overly pliable cartilage may not provide the structural support the technique requires.</p> <p><strong>Hump morphology</strong> matters as well. Preservation technique is most straightforwardly applied to humps that are primarily cartilaginous or that involve a smooth osseocartilaginous transition. Humps with significant bony irregularity, or those that are very large, may require a modified approach.</p> <p><strong>Septal anatomy</strong> is critical for the let-down technique specifically. If the septum is significantly deviated or if there is insufficient septal height to allow the required shortening, the let-down approach is not feasible. In these cases, the push-down technique or a hybrid method is considered.</p> <h2>Preservation rhinoplasty and the tip</h2> <p>A common misconception is that preservation rhinoplasty addresses only the dorsum. The technique is primarily defined by its approach to the bridge, but the tip is almost always part of the surgical plan. Tip refinement, rotation, and projection can all be achieved through preservation-compatible manoeuvres — including tongue-in-groove setback, lateral crural strut grafts, and suture techniques that reshape the lower lateral cartilages without excising them.</p> <p>The principle of tissue conservation extends to the tip work as well. Where conventional rhinoplasty might trim the cephalic edge of the lower lateral cartilages to reduce bulk, preservation-oriented surgeons prefer to reposition and reshape the cartilage using sutures, preserving the structural integrity of the tip support mechanism. This reduces the risk of long-term tip ptosis — the gradual downward rotation of the tip that can occur years after surgery when cartilage has been over-resected.</p> <h2>What the recovery looks like</h2> <p>One of the most consistent observations from surgeons who have transitioned to preservation technique is that swelling resolves more quickly and more predictably than with conventional rhinoplasty. When the dorsal framework is preserved rather than disrupted, there is less tissue trauma, less dead space, and a more intact lymphatic drainage system. The body is healing a repositioned structure, not a reconstructed one.</p> <p>In practical terms, patients typically see a more recognisable result at the two-week mark than they would following conventional rhinoplasty. The cast comes off at approximately one week. Significant bruising and swelling have usually resolved by ten to fourteen days.</p> <ul> <li>Cast removal at approximately one week post-operatively</li> <li>Significant bruising and swelling typically resolved by 10–14 days</li> <li>Presentable for most social and professional settings by two weeks</li> <li>Tip refinement continues over 6–12 months</li> <li>Final result generally visible earlier than with conventional rhinoplasty</li> <li>Lower incidence of prolonged swelling at the dorsum</li> </ul> <h2>Revision rates and long-term outcomes</h2> <p>The revision rate in rhinoplasty is higher than in almost any other elective surgical procedure — estimates in the surgical literature range from 5% to 15%. Preservation rhinoplasty is associated with lower revision rates in published series, for reasons that are structurally logical: when the native anatomy is maintained, there is less risk of the tissue distortions, asymmetries, and functional problems that sometimes emerge years after conventional reduction rhinoplasty.</p> <p>Long-term, the preserved structures continue to age naturally. The nose does not have the same tendency toward the characteristic "operated" appearance — the over-rotated tip, the pinched bridge, the visible irregularities — that can emerge over time when cartilage has been aggressively removed.</p> <blockquote>"We are not building a new nose. We are refining the one that is already there — and that distinction makes an enormous difference to how the result looks ten years from now."</blockquote> <h2>Is preservation rhinoplasty right for you?</h2> <p>The honest answer is that it depends on your anatomy, and that determination cannot be made from photographs alone. Dr. Buonassisi uses a combination of clinical examination, computer imaging, and a detailed discussion of your goals to determine which approach — preservation, conventional, or a hybrid of the two — will produce the best result for your specific nose.</p> <p>Preservation rhinoplasty is not a universal solution. It is one approach among several, and the right approach is always the one that is best suited to the individual patient's anatomy and goals. What Dr. Buonassisi brings to the consultation is the ability to offer all of these approaches and to select among them based on what your nose actually requires — not on a preference for any single technique.</p> <h2>Common questions about preservation rhinoplasty</h2> <h3>Does preservation rhinoplasty work for ethnic rhinoplasty?</h3> <p>It can, but the application requires careful assessment. Patients with thicker skin — common in certain ethnic backgrounds — may not see the same degree of dorsal refinement, because the skin envelope does not drape as closely over the repositioned framework. In these cases, Dr. Buonassisi may recommend a hybrid approach, combining preservation technique at the dorsum with conventional refinement at the tip, or may advise that conventional technique will produce a more predictable result.</p> <h3>Is preservation rhinoplasty suitable for revision cases?</h3> <p>Generally, no. Preservation technique is most effective when the native anatomy is intact. In revision cases, the original structures have often been altered, removed, or replaced with grafts, which means the anatomical conditions that preservation technique depends on are no longer present. Revision rhinoplasty typically requires a different set of reconstructive approaches.</p> <h3>How does preservation rhinoplasty affect breathing?</h3> <p>Preservation technique is generally considered favourable for nasal function. Because the internal valve architecture is not disrupted, the structural support for the airway is maintained. In many cases, functional improvements — such as septoplasty or turbinate reduction — can be performed concurrently without compromising the preservation approach at the dorsum.</p> <h3>What is the difference between let-down and push-down?</h3> <p>Both techniques lower the dorsal profile without removing it, but they do so through different mechanisms. The let-down technique shortens the septum at its caudal base, which allows the entire dorsal framework to descend. The push-down technique releases the nasal bones from their periosteal attachments and uses controlled pressure to compress the dorsum inferiorly. The choice between them depends on the patient's septal anatomy, the size of the hump, and the degree of reduction required.</p>
