Bony Dorsal Preservation.

Rhinoplasty is undergoing a transformation with the re-emergence of Dorsal Preservation Rhinoplasty (DPR) techniques. This article introduces a novel addition to the DPR repertoire, "Bony Dorsal Preservation" (BDP), which has particular application for the correction of crooked noses. In this comprehensive overview, we summarize current DPR concepts and techniques, the intricate considerations that go into the dorsal osseocartilaginous vault and septal management, and how these are modified to treat the crooked nose. However, current DPR techniques, particularly the Low Septal Strip (LSS), have drawbacks, and the desire to address such issues led to the development of BDP. BDP is ideal for cases where there is no septal base pathology. It maintains the core principle of DPR by lowering dorsal humps without creating open roof deformities. Its unique feature lies in the temporary separation of the upper lateral cartilages from the septum while leaving the septal base attachment intact, thus allowing the entire osseocartilaginous vault to be adjusted independently before reconnecting the preserved upper lateral cartilages. This technique offers direct visualization during septal excision and fixation and enables cartilaginous vault movement without sacrificing stability. Compared to LSS, there is more septal cartilage available for harvesting, the risks of a single point of septal fixation are eliminated, and there is the potential to transition to component reduction techniques if needed. With shared indications and contraindications with other DPR methods, BDP emerges as a valuable addition to the evolving field of rhinoplasty, particularly in addressing the challenges of the crooked nose.

Dorsal Preservation Rhinoplasty.

Controversies in Preservation Rhinoplasty" explores the nuanced indications, techniques, and challenges in preservation rhinoplasty (PR), featuring contributions from JC Neves, D Toriumi, and A Göksel. Neves recounts his early career under Wilson Dewes and describes the evolution of PR techniques. Toriumi, having started PR in 2019, discusses his initial cautious approach and subsequent expansion to include patients with more diverse nasal deformities. Göksel highlights the critical role of surgical expertise and individualized patient assessment, advocating for methods like dorsum-plasty osteotomies and the Ballerina maneuver to enhance PR's effectiveness.

Preventing Hump Recurrence in Dorsal Preservation Rhinoplasty: The Five Key Tenets.

SUMMARY: Preservation rhinoplasty has re-emerged over the past decade and continues to gain traction in the rhinoplasty community. Dorsal preservation rhinoplasty (DPR), one of the tenets of preservation rhinoplasty, centers on preservation of the native osseocartilaginous joint of the dorsum, with changes instead achieved through modification of the underlying septal cartilage and surrounding bony nasal pyramid. However, one complication unique to DPR is the phenomenon of hump recurrence, where tensile forces or memory lead to a recurrent convexity of the dorsal hump. Hump recurrence is the most common complication after DPR and often requires revisionary surgery. Accordingly, strategies to reduce the incidence of hump recurrence are highly sought after. In this article, we describe the senior author's main tenets of preventing hump recurrence in DPR, focusing on 1. Appropriate patient selection; 2. Addressing anatomic blocking points; 3. Adding mechanical fixation of the cartilaginous vault with suture techniques depending on the level of septal manipulation; 4. Applying a graduated approach to DPR procedural selection; and 5. Ancillary measures to control the shape of the nasal dorsum. Implementation of each of these five tenets is critical for modern rhinoplasty surgeons to reduce the incidence of hump recurrence in their preservation rhinoplasty practices.

The Effect of Cannula Drain in Reducing Edema and Ecchymosis after Rhinoplasty.

Rhinoplasty is one of the most common plastic surgeries and is commonly associated with postoperative edema, ecchymosis, and pain which play a role in patients' dissatisfaction. In this randomized comparative study, we discuss the effect of cannula drainage in the reduction of postoperative periorbital edema, ecchymosis, pain, and nasal obstruction after open structural septorhinoplasty. The study was conducted at a tertiary referral center from April to November 2022. We performed internal lateral osteotomy on all patients using the lateral saw and aided by lateral osteotome. At the end of the procedure, a cannula drain is prepared and inserted in the subperiosteal tunnel on the left side only. Patients were examined on the 1st, 3rd, 7th, 14th, and 21st days for periorbital edema, ecchymosis, pain, and nasal obstruction, and each side is scored separately. A total of 40 patients (80 sides in total) were recruited, 22 females (55%) and 18 males (45%), all of whom were adults (18-44 years old; mean age 29 years). The most frequent age group is those younger than 20 years representing 35% of the sample and the males forming 33.3%. The reduction in edema and pain was statistically significant in the drained sides (p = 0.000) during all the postoperative days. On the other hand, ecchymosis was lower on the drained side but statistically insignificant (p = > 0.29). Nasal obstruction was reduced significantly only on the seventh postoperative day (p = 0.000). The postoperative morbidities associated with rhinoplasty could have important functional and psychological effects on patients. This study demonstrates that inserting a cannula in the subperiosteal tunnel for drainage in rhinoplasty yields a significant clinical and statistical decrease in postoperative periorbital edema and pain with little effect on ecchymosis and nasal obstruction.

Low Strip Unifying Hybrid RhinoSeptoplasty (LUHRS): A Novel Classification in Dorsal Preservation Surgery.

BACKGROUND: Preservation rhinoplasty techniques continue to evolve. Suture tip-plasty with minimal resection and grafting, lateral crural tensioning, minimal excision from the lateral crura, dorsal preservation, subperichondral dissection, and preservation of the ligaments have become the milestones of modern rhino-surgery. However, every time the dorsal frame is modified by means of rasping, shaving, or osteotomy or the nasal tip is structured using grafts, we are essentially applying structural concepts to our technique. Therefore, the term "hybrid rhinoplasty" seems to include a more appropriate definition of our approach. METHODS: We performed a retrospective analysis of the medical records of patients who underwent primary septorhinoplasty using the LUHRS concept from December 2019 to June 2022. Patient functional and cosmetic satisfaction was evaluated using the Rhinoplasty Health Inventory and Nose Outcome (RHINO) scale. RESULTS: All reported procedures had low revision rates with good cosmetic and functional outcomes. CONCLUSIONS: Tailoring the surgical technique is essential in rhinoplasty. We developed and present a new technical paradigm to help surgeons choose the best approach for dorsal preservation surgery.

The Blocking Points: The Keys to Consistent Success in Preservation Rhinoplasty.

SUMMARY: Preservation rhinoplasty is a growing area of interest amongst rhinoplasty surgeons. Dorsal preservation-a tenet of preservation rhinoplasty-is predicated on maintaining the integrity of the nasal midvault and effecting aesthetic change through alterations to the bony nasal pyramid and underlying septum. A challenge that is unique to dorsal preservation is the phenomenon of hump recurrence, owing to the existence of anatomical blocking points. Blocking points are resistant tensile forces that either impede dorsal lowering intraoperatively or push the dorsum back to its native convexity over time. Five anatomical blocking points have previously been described, which the authors expand upon and include an additional two. The seven anatomical blocking points are: the cartilaginous septum, perpendicular plate of the ethmoid, lateral osteotomy site, Webster's triangle, internal mucoperiosteum of the maxillary bone, medial canthal ligament, and the lateral keystone area. It is critical that the surgeon be aware of the particular blocking points relevant to his or her chosen technique, and to appropriately and methodically address them to ensure consistent long-term results.

A Systematic Analysis of the Nasal Septum in Crooked Noses and Suggested Treatment Algorithm According to Preservation Rhinoplasty (PR) Principles.

BACKGROUND: A deviated nose is a common problem among patients for both cosmetic and functional reasons. The correction remains a major challenge for the rhinoplasty surgeon. Unrecognized nasal septal deviations stand as the primary reason for failed rhinoplasty outcomes. There is a paucity of data in the literature about septoplasty classifications and technical details in preservation rhinoplasty (PR) for various crooked noses. MATERIALS AND METHODS: The aim of this article is to provide a comprehensive overview of the various septum deviations according to the nasal axis. Moreover, a treatment algorithm is suggested with technical details based on PR principles. RESULTS: The directions and curvature of the cartilaginous deviation of crooked nose such as C-shaped, reverse C-shaped, straight axis deviations (I-shaped), and S-shaped are described. According to the deviation, a septoplasty classification (Type 1-Type 4) is suggested. CONCLUSIONS: On the basis of septal deviation, different PR techniques are proposed to achieve the desired straight nasal dorsum with an optimal functional outcome. Compared to the classical L-strut concept, the quadrangular cartilage remains preserved in the swinging door technique. The cartilage might be further used in the future for grafting in the hybrid structural/preservation technique if needed, ultimately saving rib cartilage and/or conchal cartilage. Finally, surgery time is reduced, and patient's morbidity remains minimal. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Open Preservation Rhinoplasty Using the Piezo Electric Instrument.

Preservation rhinoplasty represents a growing shift in rhinoplasty philosophy toward preserving structurally sound anatomy and reshaping existing nasal structures into esthetic and functional ideals. It is fast gaining popularity owing to the theoretic functional and esthetic benefits of preserving the dorsal keystone area and dorsal esthetic lines. The preservation technique is made more accessible by the open approach, which provides an opportunity for the deformity to be clearly visualized from the tip of the nose to the dorsum, as well as enables greater ease of powered instrument access. The addition of the Piezo-electric device, with its range of rhinoplasty inserts, enables more precise and accurate management of the osseocartilaginous vault, reduces the risk of surface irregularities, and hence optimizes the overall surgical outcome.

Optimization of the Soft Tissue Envelope of the Nose in Rhinoplasty Utilizing Fat Transfer Combined with Platelet-Rich Fibrin.

A thin or damaged skin soft tissue envelope may cause concerns in primary and secondary rhinoplasty. During postoperative healing, unpredictable scarring and contraction may occur and lead to significant aesthetic and trophic sequelae. Besides a meticulous surgical technique, there are no reliable techniques to prevent long-term skin damage and shrinkage. Fat transfer with addition of platelet-rich fibrin (PRF) harbors the possibility of local soft tissue regeneration and skin rejuvenation through growth factors and mesenchymal stem cells. It may also facilitate the creation of a thin fat layer on the dorsum to prevent shrink-wrap forces and conceal small irregularities. The goal is to provide evidence for the feasibility, durability, and beneficial effect of diced macrofat transfer bonded with PRF on the nasal dorsum. We present the technique of fat transfer conjugated with PRF as a nasal dorsal graft. Clinical endpoints were the prevention of trophic disturbances and atrophy at a 1-year postoperative follow-up. We present the skin mobility test as a clinical indicator of a healthy soft tissue envelope. The presented case series consists of 107 rhinoplasties. Fat was harvested in the umbilical or costal region. PRF was created by centrifugation of autologous whole blood samples. Macrofat was diced, cleaned, and bonded with PRF. The compound transplants were transferred to the nasal dorsum. There were no perioperative complications or wound-healing issues. Mean follow-up was 14 months. Clinical inspection showed good skin quality and no signs of shrinkage, marked scarring, or color changes with positive skin mobility test in all patients. Survival of fat was confirmed by ultrasonography and magnetic resonance imaging. Diced macrofat transfer in conjunction with PRF to the nasal dorsum is a feasible and safe method. A beneficial effect on the soft tissue envelope is demonstrated as well as the prevention of shrink-wrap forces.

Biomechanical Nasal Anatomy Applied to Open Preservation Rhinoplasty.

Preservation rhinoplasty is a new way to reshape the nose by preserving the dorsum, nasal ligaments, soft tissue envelope, and muscles. This new concept provides the opportunity to achieve a more natural aesthetic and functional result. To achieve a good aesthetic and functional outcome while maintaining surgical safety, knowledge of the relevant anatomy is key. This is especially true for the preservation rhinoplasty technique, where a firm grasp of the anatomy of the nasal soft tissue and bony-cartilaginous framework is critical. The preservation technique is made more accessible by the open approach, which provides an opportunity for the deformity to be clearly visualized from the tip of the nose and the dorsum. Furthermore, tip plasty is easier to perform under direct vision, which is an advantage of the open approach. The goal of this article is therefore to make clear all the important anatomical structures and their relevance to the surgical steps taken when performing the open preservation rhinoplasty technique.

Awareness of Facial Asymmetry and Its Impact on Postoperative Satisfaction of Rhinoplasty Patient.

INTRODUCTION: Rhinoplasty surgeons often find that despite their best efforts to straighten the nose, patients often continue to perceive their nose as deviated, and this perception is particularly prevalent in patients with concurrent facial asymmetry. The aims of this study were to determine whether facial asymmetry influences the satisfaction of rhinoplasty patients and whether there is a difference in postoperative happiness between patients with and without facial asymmetry. MATERIALS AND METHODS: In this retrospective study, we reviewed the charts and photographs of patients who underwent rhinoplasty between 2016 and 2018. Patient photographs were analysed; 30 patients with facial asymmetry and 30 patients with symmetric faces were randomly selected for the study. The preoperative and postoperative rhinoplasty outcome evaluation (ROE) and standardized cosmesis and health nasal outcomes survey (SCHNOS) scores were compared between the two groups. RESULTS: The mean preoperative symmetry scores of the group with facial asymmetry were significantly higher than those of the group with symmetric faces. The magnitude of increase in the average ROE score from pre- to postoperatively was significantly larger in the group with symmetric faces than in the group with facial asymmetry. The magnitude of decrease in the mean SCHNOS score from pre- to postoperatively was significantly larger in the group with symmetric faces than in the group with facial asymmetry (p: 0.006). CONCLUSION: It is important to clearly evaluate patients with facial asymmetries before surgery to increase their postoperative satisfaction and outcomes and make their expectations more realistic.

Piezoelectric Osteotomies in Dorsal Preservation Rhinoplasty.

Dorsal preservation rhinoplasty requires precise management of the osseocartilaginous vault. Ultrasonic piezo instruments offer several advantages compared with traditional tools such as hand saws, rasps, and osteotomes. As always, an understanding of the dynamics of manipulation of the vault, anatomy, and proper technique are paramount and are reviewed herein.

Options for Middle Vault and Dorsum Restoration after Hump Removal in Primary Rhinoplasty.

Prevention of unfavorable sequelae following humpectomy in reduction rhinoplasty by restoration of the middle nasal vault complex today has become imperative in the majority of patients with perhaps the exception of small humps. In general, the techniques used for preservation and reconstruction of these important anatomical structures can be divided into two main categories: spreader graft and spreader flap techniques. Oversimplified spreader graft techniques require donor cartilage, whereas spreader flap techniques use the excess height of the medial portion of the upper lateral cartilages in patients with a cartilaginous hump. In principle, both donor cartilage and preserved upper lateral cartilages usually are positioned along both sides of the dorsal septum to provide natural and harmonious contours as well as to avoid functional impairment (valve collapse). However, the considerable number of publications on this topic attests to existing downsides of both surgical principles. To overcome these shortcomings, we illustrate additional modifications in the application of spreader grafts as well as spreader flaps. However, the main goal of this article is to provide an algorithm helping to decide which technique is best suited to meet the requirements of each individual patient.

Prolene mesh mentoplasty.

Augmentation mentoplasty is a cosmetic surgical procedure to correct chin retrusion or microgenia which usually requires placement of an alloplastic material over the pogonion, and which results in increased chin projection and a more aesthetically balanced facial profile. Polypropylene mesh is easy to purchase, widely available in a general hospital and most commonly used by general surgeons. In this series of 192 patients, we wanted to demonstrate our simple mentoplasty technique using prolene mesh that can easily be combined with a rhinoplasty procedure, with possible causes of infection and the rationale for using prolene mesh in such procedures.
