Hybrid Dorsal Preservation Rhinoplasty: Reediting an Aesthetic Dorsum.

BACKGROUND: The prerequisite of a well-shaped dorsum with proper dorsal aesthetic lines that needs no modifications in its width and symmetry is key to letdown and push-down techniques as classically described. The common current concept is that total preservation of the middle vault is obligatory. This, however, obviously limits the indications, since nasal dorsum with natural aesthetic dorsal lines per se is relatively few. The recent, impressive, revival of letdown and push-down procedures has progressively generated numerous technical variations, but all those essentially still left the middle vault unmodified. The concept of splitting the middle vault and modifying its width and symmetry, while leaving the crucial dorsal (central) and lateral Keystone area intact, represents a new hybrid approach to the nasal dorsum. The structural benefits of classical component separation are combined with the major advantage of preserving the flexible chondro-osseous joint at the keystone junction. Osteotomies and/or osteoplasty can be done as necessary to modify the bony dorsum and at the same time any type of septal deformity can be addressed according to the time-tested L-strut principle, a Cottle septoplasty included. This hybrid approach expands indications beyond those of the conventional push-down/letdown technique, including moderate asymmetries of the bony and cartilaginous dorsum. Although splitting the middle vault along the septal T will also facilitate middle vault reshaping in cases where a full letdown procedure is indicated, this paper will clarity address only those instances where no circumferential osteotomy is done. METHODS AND MATERIALS: The dorsal bony nasal pyramid is always addressed first by rhinosculpture (osteoplasty) with piezoelectric inserts and/or burrs, in combination with different types of osteotomies as needed. This will allow narrowing of the bridge and correction of bony asymmetries. The osseous-cartilaginous connection of the central dorsal keystone area (DKA) is totally preserved. At this point, three main variations are possible: Type 1) preservation of the septal T and push-down by a high-middle septal strip resection, two different variations (1A and 1B) are possible here, Type 2) reduction in width of the septal T-segment and middle vault restoration by spreader flaps without any push-down of the septal T and Type 3) preservation of the septal T and letdown by low strip resection. CONCLUSION: Hybrid Dorsal Preservation involves concepts of Structure and Preservation Rhinoplasty. Dorsal and lateral keystone area are preserved, and the middle vault could be modified splitting the septal T in the anatomical plane, expanding patient indications and improve outcomes.

The Quadrangular Cartilage in Rhinoplasty: A Surgically Focused CT Dimensional Analysis of Black African and Caucasian Populations.

The apparent lack of quadrangular cartilage in Black African noses is commonly observed both from a radiological and clinical point of view. To the best of our knowledge, only a few research papers have been conducted on the facial proportions and structural anatomy of black people of Southern and Eastern Africa. The aim of this retrospective comparative study is a radiological assessment of the total amount of septal quadrangular cartilage by measuring its area in sagittal CT views, in two selected Black South African and Caucasian (CA) samples and the comparison with the literature in our hands. Statistical analysis was conducted, categorical variables are shown as frequencies and percentages, while continuous variables as means and standard deviations. Normal distribution of variables was verified using the Shapiro-Wilk test or by means of skewness and kurtosis values. Differences among unpaired groups were evaluated using the independent Student's t-test for normally distributed data (complemented by the Cohen's d to show the effect size with the following cutoff: d = 0.2, "small" effect size; d = 0.5, "medium" effect size; d = 0.8, "large" effect size) and Mann-Whitney U test in case of non-normal distribution. Statistical significance was defined as p < 0.05 setting the α-error probability at 5%. This study shows that, on average, there is 30% more cartilage available in CA compared with Black African noses and confirms the apparent lack of quadrangular cartilage and in Black African noses which is commonly observed in surgery. The need for an adequate amount of autologous septal cartilage makes cartilage availability a major concern before surgery and being able to preoperative accurately measure the amount of septal cartilage that is available to be harvested for other grafts in the surgery is essential.

Artificial Intelligence Versus Expert Plastic Surgeon: Comparative Study Shows ChatGPT "Wins" Rhinoplasty Consultations: Should We Be Worried?

Introduction: Large language models, such as ChatGPT, hold tremendous promise to bridge gaps in patient education and enhance the decision-making resources available online for patients seeking nasal surgery. Objective: To compare the performance of ChatGPT in answering preoperative and postoperative patient questions related to septorhinoplasty. Methods: Two sets of responses were collected for the questions: one from an expert rhinoplasty surgeon with over two decades of experience, and the other from ChatGPT-3.5. Seven expert rhinoplasty surgeons, blinded to the source of responses, independently assessed the responses using a 5-point Likert scale in four performance areas: empathy, accuracy, completeness, and overall quality. Results: ChatGPT outperformed physician responses in three of the four performance areas, earning significantly higher ratings in accuracy, completeness, and overall quality (p < 0.001). In addition, ChatGPT was overwhelmingly preferred over physician responses (p < 0.001), with evaluators favoring ChatGPT in 80.95% of instances. Conclusions: ChatGPT has demonstrated its remarkable ability to deliver accurate, complete, and high-quality responses to preoperative and postoperative patient questions. Although certain improvements are warranted, this artificial intelligence tool has shown its potential to effectively counsel and educate prospective septorhinoplasty patients at a level comparable with or exceeding that of an expert surgeon.

RIB Plaster: a versatile, moldable derivative from scraping the periphery of the rib.

A simple technique is described for obtaining "rib plaster" by scraping the whitish peripheral portion of residual segments of rib after the perichondrium is removed and appropriate multiple laminations are derived This putty-like substance tends to conglomerate appropriately due to its high density and has unique properties: readily compacted into diced cartilage inserters, smoothly injected, easily moldable. "Rib plaster" serves well for camouflage of irregularities of the dorsum and tip as well as for mild augmentation. It comes to no further cost and in an adequate supply once a full-thickness rib segment is harvested for secondary rhinoplasty.

Efficacy of Septoplasty in Patients with Nasal Obstruction: A Systematic Review and Meta-analysis.

OBJECTIVE: Septoplasty is the most frequently performed ENT surgery to correct nasal septal deviation (NSD). The present study aimed to quantify the effectiveness of septoplasty with or without turbinate surgery according to NOSE questionnaire scores, with the hypothesis that it is able to clinically improve patient-reported nasal obstructive symptoms in the post-operative follow-up. METHODS: An electronic search was performed on PubMed/MEDLINE, Embase, and Cochrane Library. The primary outcome was the change in NOSE score at 6 months after surgery. It was assessed with the mean difference (MD) between baseline and postoperative results. RESULTS: A total of 2577 patients (males: 65.1%, 95% CI: 59.9-70.2) with a mean age of 33.3 years (n = 1456, 95% CI: 30.4-36.2) were included in this meta-analysis. The pooled baseline NOSE mean score was 68.1 (n = 2577, 95% CI: 64.3-71.9). The pooled MD in NOSE score at 6-months follow-up compared to baseline was -48.8 (n = 1730, 95% CI: -54.6 to -42.9). CONCLUSIONS: Functional septoplasty with or without turbinate surgery shows a critical improvement of obstructive symptoms and quality of life according to the validated NOSE score.

Modified Dorsal Split Preservation Hybrid Rhinoplasty for Cartilaginous Pushdown and Full Letdown Applications: A PROM-Based Review of 100 Consecutive Cases.

Splitting the middle vault on an anatomical plane along the "Septal T" allows a new hybrid perspective on the many modifications of "surface" preservation techniques. The "dorsal split preservation" concept can be applied both to cartilaginous pushdown as well as to full letdown techniques. The dorsal keystone area is maintained, while the middle vault is reshaped. The septum is addressed by conventional L strut septoplasty. Precise direct suture fixation of the high-middle strip is easily accomplished after flexing the osseous-chondral junction at the K area. Specific technical points are described to allow exact and stable configuration of the dorsum.A retrospective analysis on 100 consecutive patients demonstrated aesthetic and functional improvement.

The "3 Points Compartmentalization" Technique in Subperichondrial-Subperiosteal Dissection in Primary Rhinoplasty to Reduce Edema and Define Contour.

Proper control of postoperative edema in rhinoplasty matters significantly, both regarding patient satisfaction and preventing loss of definition and aesthetic surface contour in the dorsum and tip. The "3 points compartmentalization" technique described in this paper aims to fulfill the above goals by (1) dissection in a subperichondrial-subperiosteal plane and (2) reducing the dead space by three strategically placed key sutures that compartmentalize the nose and redrape the single-plane dissection in an anatomically correct position.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Current Practices in Dorsal Augmentation Rhinoplasty.

BACKGROUND: Dorsal augmentation rhinoplasty addresses the aesthetic and functional impairments caused by a deficient nasal dorsum. Augmentation rhinoplasty can be performed using a variety of different surgical techniques and grafting materials that all have distinct advantages and disadvantages. METHODS: Grafting materials have unique characteristics, uses, and safety profiles. A detailed overview of various grafting materials and their uses, risks, and benefits is provided. RESULTS: Autologous grafting materials include septal cartilage, auricular cartilage, and costal cartilage. These donor sites can provide various amounts of en bloc or diced cartilage. Alternatively, bone may be used when strong structural stability is required, and soft tissue may be used to fill mild to moderate defects. Homologous grafts (e.g., irradiated and nonirradiated rib) and acellular dermal matrices are alternatives to autologous graft with many similar advantages and no need for an additional surgical site. Lastly, alloplastic implants may be successfully used for dorsal augmentation if both patient and surgeon understand their associated risks. CONCLUSION: To perform successful dorsal augmentation, surgeons should be familiar with the wide variety of operative approaches and augmentation materials that are currently available and understand their risks, benefits, and uses.

Three-Dimensional Technology in Rhinoplasty.

Rhinoplasty is uniquely suited to capitalize on different aspects of three-dimensional (3D) modeling technology. Currently, 3D surface imaging of preoperative and postoperative nasal structure provides a platform for better surgical planning and patient counselling as well as objective postoperative measurements. Physical nasal models using 3D printing technology can improve rhinoplasty performance intraoperatively, postoperative outcomes, together with nasal prosthetic manufacture, by tailoring to specific patient anatomy. Advances in tissue engineering using 3D-printed biocompatible scaffolds have shown excellent nasal cartilage mimicry and hold promise for increasingly versatile directed tissue regeneration in rhinoplasty and nasal reconstructive surgery. As health care innovations are expected to become increasingly common in standard rhinoplasty practices in the future, we give an account of how 3D technologies can create new opportunities to optimize surgical planning and improve overall the patient experience.

Global Practice Patterns of Dorsal Preservation Rhinoplasty.

Background: Dorsal preservation rhinoplasty (DPR) has recently received significant academic attention in part due to theoretical benefits over excisional surgical methods. The purpose of this study was to assess the global practice patterns regarding this technique. Materials and Methods: An 11-item questionnaire was electronically distributed to regional academies/societies representing rhinoplasty surgeons worldwide. Respondent exposure to and use of DPR were assessed based on geographic location. Results: Eight hundred thirty-six responses were received. Despite early publications on DPR originating largely from Western Europe and the United States, Turkey and Mexico have the greatest use of DPR techniques currently. The familiarity across many regions with preservation techniques appear to be secondary to courses and conferences rather than incorporation into training. Mexico demonstrates the greatest exposure to DPR during training. One hundred twenty-five respondents had previously used but abandoned dorsal preservation techniques. Poor results, less predictability, and complications (largely hump recurrence) are cited as common reasons for this. Conclusion: There is variability in the global practice of DPR across regions and this will likely continue to evolve.

Rhinosurgery during and after the COVID-19 Pandemic: International Consensus Conference Statement on Preliminary Perioperative Safety Measures.

BACKGROUND: The coronavirus disease of 2019 (COVID-19) pandemic has widely affected rhinosurgery, given the high risk of contagion and the elective nature of the aesthetic procedure, generating many questions on how to ensure safety. The Science and Research Committee of the Rhinoplasty Society of Europe aimed at preparing consensus recommendations on safe rhinosurgery in general during the COVID-19 pandemic by appointing an international panel of experts also including delegates of The Rhinoplasty Society. METHODS: A Zoom meeting was performed with a panel of 14 international leading experts in rhinosurgery. During 3.5 hours, four categories of questions on preoperative safety measures in private practice and outpatient clinics, patient assessment before and during surgery, and legal issues were presented by four chairs and discussed by the expert group. Afterward, the panelists were requested to express an online, electronic vote on each category and question. The panel's recommendations were based on current evidence and expert opinions. The resulting report was circulated in an iterative open e-mail process until consensus was obtained. RESULTS: Consensus was obtained in several important points on how to safely restart performing rhinosurgery in general. Preliminary recommendations with different levels of agreement were prepared and condensed in a bundle of safety measures. CONCLUSION: The implementation of the panel's recommendations may improve safety of rhinoplasty by avoiding operating on nondetected COVID-19 patients and minimizing severe acute respiratory syndrome coronavirus 2 virus spread in outpatient clinics and operating rooms.

Cone-Beam Computed Tomography: A User-Friendly, Practical Roadmap to the Planning and Execution of Every Rhinoplasty-A 5-Year Review.

BACKGROUND: Cone-beam computed tomography has recently rapidly developed worldwide as a versatile and convenient alternative to traditional computed tomography for imaging of the maxillofacial region. However, most surgeons performing rhinoplasty are surprisingly unfamiliar with it, in both the plastic surgery and ear, nose, and throat communities. METHODS: The broad clinical experience of a single center over the past 5 years is reviewed. The many applications of cone-beam computed tomography to primary and secondary rhinoplasty are analyzed regarding septum, turbinates, nasal bones, skin thickness, and other issues. The importance of a paradigm shift from a two-dimensional to a three-dimensional approach in image reconstruction is demonstrated, together with the value of surface contour enhancement. RESULTS: Cone-beam computed tomography has a multitude of practical applications highly relevant to rhinoplasty. The surface image will strengthen aesthetic analysis, and the detailed preview of bony and functional anatomy will facilitate surgical planning. Cone-beam computed tomography serves as a roadmap to plan and execute rhinoplasties more predictably and efficiently. The availability of spatial views and accurate detail, together with the possibility of easy, accurate measuring, offers a plenitude of potential applications. CONCLUSIONS: Cone-beam computed tomography is a user-friendly, quick technique with abundant advantages in planning any rhinoplasty. It causes the patient no inconvenience and has very few, if any, drawbacks, with these being limited to radiation exposure and limited cost.
