The alar contour graft: correction and prevention of alar rim deformities in rhinoplasty

Management of alar webbing using a CAD-CAM splint: A case report

Alar webbing is a functional and aesthetic defect of the nasal structure noted in cleft lip and palate patients (CLP), which is thought to be due to a deficiency in nasal lining tissue. Surgical procedures have previously focused on the removal of lining or alar cartilage leading to worse post-operative defects. This case demonstrates a novel technique of releasing the tissue, followed by using a CAD-CAM splint to help mold the tissue during the healing process to better control esthetics, symmetry, and prevent relapse. The release of scarred tissue using a custom CAD-CAM stent is a promising technique that allows for symmetric healing and an overall aesthetic surgical result for patients.

The Alar Extension Graft Technique for the Treatment of External Nasal Valve Collapse: Preliminary Results of a Single-Centre Prospective Analysis

BACKGROUND

The aim of this study is to describe the efficacy of the alar extension graft for the correction of external nasal valve collapse and to evaluate the functional and aesthetic results.

METHODS

The study included 51 patients who underwent alar extension grafting for external nasal valve collapse. Pre- and post-operative rhinomanometry was performed before and after surgery. NOSE and SNOT 20 questionnaires were completed before and 9 months after surgery. Patients were also asked about their post-operative satisfaction.

RESULTS

90% of patients were subjectively satisfied with the post-operative improvement in nasal breathing. There was a significant improvement in the values of the pre- and post-operative NOSE and SNOT 20 questionnaire scores. Rhinomanometry showed increased nasal flow with a statistically significant difference between pre- and post-operative results.

CONCLUSIONS

The alar extension graft has been proved to be effective and reliable in the surgical treatment of external nasal valve collapse, improving the patients' objective and subjective breathing with good functional and aesthetic results.

Finesse in Primary Open Rhinoplasty

SUMMARY

Rhinoplasty remains one of the most technically demanding operations in plastic surgery, and it continues to be one of the top 5 aesthetic surgical procedures performed. The focus of this article is open rhinoplasty, the central focus of the practice of the senior author (R.J.R.) over the past 3 decades. The authors provide a step-by-step video guide to the typical sequence of the senior author's technique.

Refinements in Extended Alar Contour Grafts: Retrograde Approach in Conjunction with Alar Base Surgery

SUMMARY

Alar contour grafts are an excellent adjunct in both primary and revision rhinoplasty for correction and prevention of alar rim irregularities. They are traditionally placed at the conclusion of a rhinoplasty through a vestibular incision along the underside of the alar rim. Alternatively, alar base resection provides an opportunity for precise retrograde placement of alar contour grafts. The purpose of this article is to describe an efficient, five-step technique for retrograde placement of alar contour grafts in the setting of concomitant alar base surgery.

Lateral Overlay Sliding Transposition (LOST): A Novel Surgical Technique in Patients with Cephalic Malposition and Alar Retraction

OBJECTIVE

This study aims to demonstrate a new surgical technique that can be applied in patients with cephalic malposition and patients with alar retraction.

METHODS

In this technique, a cartilage incision is made between the upper 2/3 and lower 1/3 close to the caudal edge and parallel to the cephalic edge of the lateral crus. Following this incision, the cephalic lateral crus and middle crus are meticulously dissected away from the underlying vestibular skin. The prepared flap is transposed over the intact caudal part of the lateral crus and secured in position.

RESULTS

The average age of the patients included in the study was 24 years. The mean follow-up period was nine months, ranging from 6 to 12 months. No complications were observed following the application of the technique. Satisfactory outcomes were achieved postoperatively.

CONCLUSION

Lateral overlay sliding transposition as a novel surgical technique has been demonstrated in patients presenting with cephalic malposition, mild to moderate alar retraction, and alar irregularity.

Clinical Practice Patterns and Evidence-Based Medicine in Rhinoplasty: A 10-Year Review of Continuous Certification Tracer Data from the American Board of Plastic Surgery

BACKGROUND

The American Board of Plastic Surgery (ABPS) has collected data on cosmetic surgery from member surgeons since 2003. These data offer valuable information on national trends in clinical practice.

OBJECTIVES

The present study was performed to analyze trends in rhinoplasty over the last decade.

METHODS

Tracer data were compared between two cohorts 2012-2016 (early cohort "EC") and 2017-2021 (recent cohort "RC"). Data included patient demographics and surgical techniques. Results were considered in the context of current EBM-based guidance in the plastic surgery literature.

RESULTS

Data from 730 rhinoplasties (270 EC and 460 RC) were analyzed. The median age was 30 years, and the most common patient concern was the nasal dorsum (79%). In the RC group, fewer patients voiced concerns about tip projection (58% vs 43%, p = 0.0002) and more complained of functional airway problems (38% vs 49%, p = 0.004). An open approach was most common (83%). Septoplasty (47% vs 52%, p = 0.005), caudal septum repositioning (14% vs 23%, p = 0.002), and tip rotation maneuvers (32% vs 49%, p < 0.0001) became more popular. There was also an increase in the use of spreader grafts (35% vs 45%, p = 0.01) and columellar strut grafts (42% vs 50%, p = 0.04), while there has been a decrease in alar base resection (17% vs 10%, p = 0.007) and non-cartilaginous dorsum/radix augmentation (9% vs 4%, p = 0.02).

CONCLUSIONS

ABPS tracer data provide an excellent resource for the objective assessment of procedures in plastic surgery. The present study is the first to highlight evolving trends in rhinoplasty over the last 10 years.

Lateral Crural Repositioning: Implications on Nasal Function

There are many concepts for surgical management of the nasal tip with varying outcomes on esthetics and nasal function. Nasal tip surgery can influence nasal function based on how the techniques can alter lateral wall integrity. A retrospective chart review of rhinoplasty patients undergoing lateral crural strut grafting (LCSG) with and without repositioning from 2009 to 2017 of the primary author (D.M.T.) was performed. Preoperative and postoperative Nasal Obstruction Symptom Evaluation (NOSE) scores were analyzed. In our study, 832 subjects were evaluated. The mean preoperative NOSE score of all subjects was 35.48. The longest follow-up mean was 652.07 days with a mean NOSE score of 7.07 (p < 0.0001). In the LCSG group, the mean preoperative NOSE score was 22.97. The longest follow-up mean was 583.29 days with a mean NOSE score of 7.22 (p < 0.0001). In the LCSG with repositioning group, the mean preoperative NOSE score was 43.42. The longest follow-up mean was 692.36 days with a mean NOSE score of 7.60 (p < 0.0001). LCSGs with or without repositioning improves nasal function showing significant improvement in NOSE scores. The use of these techniques require adhering to several technical points to maximize outcomes and to avoid deformity.

Ethnically Sensitive Rhinoplasty

Ethnically sensitive rhinoplasty presents a unique challenge. There are a large number of variations in skin tone, skin thickness, and structural deformities, which require a high degree of thoughtfulness and planning. A thorough history and physical examination are the cornerstone to achieving a good result. An open and honest discussion is necessary to fully understand the patient's goals. The surgeon should clearly define which goals are achievable and which are not. An individualized approach with special consideration toward maintaining ethnic heritage is imperative. Conservative techniques will help achieve a natural, balanced outcome and will allow for preservation of nasal function.

External Z-plasty Technique for Correction of Alar Retraction in Asian Patients

BACKGROUND

Current strategies for correcting alar retraction mainly include cartilage grafting and composite grafting, which are relatively complicated and may produce injury to the donor site. Herein, we introduce a simple and effective external Z-plasty technique for correcting alar retraction in Asian patients with poor skin malleability.

METHODS

Twenty-three patients were presented with alar retraction and poor skin malleability, and they were very concerned about the shape of the nose. These patients undergoing external Z-plasty surgery were analyzed retrospectively. In this surgery, no grafts were needed, and the location of the Z-plasty was according to the highest point of the retracted alar rim. We reviewed the clinical medical notes and photographs. During the postoperative follow-up period, patients' reported satisfaction with aesthetic outcome were also evaluated.

RESULTS

The alar retraction of all the patients was successfully corrected. The postoperative mean follow-up period was 8 months (range: 5-28 mo). No incidents of flap loss, recurrence of alar retraction, or nasal obstruction were observed during postoperative follow-up. Within postoperative 3-8 weeks, minor red scarring was visible at the operative incisions in most patients. However, these scars turned unobvious after postoperative 6 months. There were 15 cases (15/23) being very satisfied with the aesthetic outcome of this procedure. Seven patients (7/23) were satisfied with the effect and the invisible scar of this operation. Only one patient was dissatisfied with the scar, but she was satisfied with the correction effect of the retraction.

CONCLUSION

This external Z-plasty technique can be an alternative method for correction of alar retraction with no need of cartilage grafting, and the scar can be unobvious with fine surgical suture. However, the indications should be limited in patients with severe alar retraction and poor skin malleability, who should not particularly care about the scars.

Septal Advancement Flap: Preserving, Restructuring, and Reshaping the Nasal Tip Contour with a Novel Flap

Tip support and the tip's exact final position-rotation and projection-remain a main concern among rhinoplasty surgeons. The available options can be classified into two groups: septal extension graft (variations including tongue-in-groove) and columellar strut (with all its variations). There is still the possibility of nasal tip ligament(s) preservation-namely the interdomal ligament, when anchoraged cephalically to the anterior septal angle preserving the tip support. Including this panoply of solutions, the author has identified some challenges with insufficient outcome. Based on engineering concepts, a novel septal flap was developed to facilitate a preferred tip position and shape. The septal advancement flap (SAF) is a rotational-advancement flap of the superior and caudal aspects of the cartilaginous septum that enables the surgeon to create stable and accurate tip shape and position. This flap was designed following the spare roof technique B sequence, although it can be completed along with any technique of structure or preservation rhinoplasty.

A New Technique for Use Instead of Lateral Crural Overlay for Reduction of Nasal Tip Projection in Revision Rhinoplasty

Objective

Correction of nasal tip projection (NTP) deformities involve techniques for the lower lateral cartilage of the nose. Previously, it would have been surgically difficult to perform the lateral crural overlay (LCO) technique for the second time in revision rhinoplasty in patients who already had undergone rhinoplasty with the LCO technique because of the length of the NTP. In this study, we evaluated the lateral crural segmental excision (LCSE) technique in patients with overprojected nasal tip in revision rhinoplasty.

Methods

We retrospectively studied the cases of 19 patients who had initially undergone rhinoplasty with the LCO technique for overprojected nasal tip, and later underwent revision rhinoplasty with the LCSE technique after insufficient NTP was observed on facial analysis between 2018 and 2022.

Results

Of the patients, 12 (63%) were male, with an average age of 29.6 years, and 7 (17%) patients were female, with an average age of 25.3 years. Using Goode's formula, NTP indexes of patients measured 79.4±1.8 preoperatively and 56.0±1.3 postoperatively. Stastically significant difference was observed between preoperative and postoperative values. None of the patients had malnutrition at the incision margins, and all patients recovered on time and without any problems. Granulation tissue was detected in the mucosa in only one patient.

Conclusion

The LCSE technique, with a short surgical time, recovery period without complications, and satisfactory nasal respiratory function, is preferred over a second LCO application in cases of NTP.

A novel classification of alar retraction based on nostril exposure in Asian rhinoplasty

OBJECTIVE

Alar retraction is considered a challenge in rhinoplasty. The classification of alar retraction remains poorly defined, especially in Asia. Patients with alar retraction are associated with excessive exposure to the nostrils in Asia. This study aimed to introduce a classification method of alar retraction based on nostril exposure.

MATERIALS AND METHODS

Medical records of patients who had undergone rhinoplasty with alar retraction based on nostril exposure between January 2015 and December 2020 were retrospectively reviewed. The corrections of alar retraction were categorized into three groups according to a classification method of alar retraction based on nostril exposure: mild alar retraction, moderate alar retraction, and severe alar retraction. The visual analog scale (VAS) and rhinoplasty outcomes evaluation (ROE) were used to evaluate the satisfaction rate.

RESULTS

Within a median period of 13.3 months, 45 patients (51.14%) with mild alar retraction were corrected by alar contour graft. 23 patients (26.14%) with moderate alar retraction were treated with the alar contour graft(n=10), the lateral crural strut graft (n = 6), and the alar projection graft (n = 7). 20 patients (22.73%) with severe alar retraction were corrected by lateral crural strut graft combined with composite graft (n = 6), lateral crural strut graft (n = 10), and composite graft (n = 4). The severe alar retraction group had a higher satisfaction rate in ROE(P<0.05) and VAS (P<0.05) than moderate alar retraction and mild alar retraction at a follow-up of 12 months after surgery.

CONCLUSIONS

The classification of alar retraction based on nostril exposure is more practical for rhinoplasty in Asia.

Cosmetic Rhinoplasty

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Perform a systematic nasofacial analysis. 2. Identify the underlying anatomical cause of specific external nasal findings. 3. Recognize the interrelated effects of operative maneuvers. 4. Develop an appropriate operative plan to address patient concerns.

SUMMARY

The rhinoplasty operation is one of the most challenging procedures in plastic surgery, and requires a combination of surgical judgment, knowledge of anatomy, technical skill, and lifelong study. A foundation must be built on clearly defined patient goals and an accurate diagnosis, based on known ideals and their anatomical correlation. It is important to recognize the definitive impact of each operative maneuver to achieve predictable outcomes. This article provides a problem-based approach to common cosmetic nasal deformities.

Nasal Tip Remodeling Using Autologous Cartilage Grafts: Systematic Review

OBJECTIVE

The objective of this study was to perform a systematic review of the literature to assess the clinical outcomes and safety profile of autologous cartilage grafts (A-CGs) in nasal tip remodeling (NTR).

METHODS

The protocol was developed following the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses-Protocols guidelines. A multistep search of the PubMed, MEDLINE, Embase, Scopus database, and Cochrane databases has been performed to identify papers on A-CGs use in NTR. Of the 253 articles initially identified, only 39 articles providing either retrospective (n = 35) or prospective (n = 4) data about outcomes, descriptions, and complications of the A-CGs use in NTR were selected. Of these, 3 articles focused on alloplastic grafts were excluded.

RESULTS

The nasal septum, concha, and ribs have been the main donor sites to build A-CGs to be used in NTR. Septal cartilage turned out to a specific and versatile, useful for many types of grafts tools, presenting a low rate of resorption, extrusion, and warping. Auricular concha cartilage has been used to correct both the internal and external nasal valve collapse, whereas rib chondral grafts have been used to improve the structural support when septal cartilage was not available. Crushed cartilage, minced cartilage, and diced cartilage have been used in noses with thinner soft tissues.

CONCLUSIONS

Eighty percent of the analyzed studies focused on the description of the adopted surgical technique and A-CGs procedures of preparation, displaying encouraging aesthetic and functional outcomes with generally low levels of complications. Collected data confirmed the safety and efficacy of A-CGs-related interventions in NTR without major side effects.

Functional Nasal Surgery

LEARNING OBJECTIVES

After studying this article, the participant should be able to: (1) understand the functional significance of nasal anatomy as it relates to rhinoplasty and perform a comprehensive functional nasal assessment. (2) Identify the anatomical level of obstruction based on the authors' algorithmic approach and understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, external nasal valve collapse. (3) Understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, and external nasal valve collapse. (4) Appreciate the objective assessment tools for functional nasal surgery from a clinical and research perspective.

SUMMARY

The intent of functional rhinoplasty is to improve nasal airflow (and the perception thereof) by surgically correcting the anatomical sources of obstruction in the nasal airway. Cosmetic and functional rhinoplasty are not mutually exclusive entities, and the techniques that address one area, inevitably may affect the another. The rate of functional problems after cosmetic rhinoplasty range from 15 to 68 percent with nasal airway obstruction found to be the most common indication for secondary surgery. The objective of this CME article is to provide readers with an understanding of the (1) functional components of nasal anatomy, (2) clinical functional assessment, and (3) the current evidence supporting corrective maneuvers for each component.

Structural Preservation Rhinoplasty: A Hybrid Approach

SUMMARY

Structural preservation rhinoplasty merges two popular philosophies of rhinoplasty-structure rhinoplasty and preservation rhinoplasty-in an effort to maximize patient outcomes, aesthetics, and function. This allows the surgeon to both preserve the favorable attributes of the nose, and also to structure the nasal tip and dorsum with grafts to maximize contour and support. The concept of dorsal preservation is to preserve favorable dorsal aesthetic lines without the creation of an "open roof." However, the addition of some structure concepts can expand the utility of dorsal preservation in primary rhinoplasty patients. The authors discuss these structure concepts and their applicability to dorsal preservation.

Correction of the Nasal Ala

None.

Cleft Rhinoplasty

An understanding of anatomy and pathophysiology of the cleft nasal deformity is crucial to its management, including selection of correct surgical techniques for repair. Timing of intermediate and definitive rhinoplasty should be considered carefully, with definitive rhinoplasty occurring after management of facial skeletal deformities. At the time of definitive rhinoplasty, the septum, external and internal nasal valves, alar base malposition (and corresponding bony deficiency), and position and shape of the lower lateral cartilage and the columella all must be individually considered. Thorough knowledge of rhinoplasty techniques is crucial to address the cleft nasal deformity with optimal functional and aesthetic outcomes.

Non-Caucasian Rhinoplasty

Today non-Caucasian patients comprise an important group of patients seeking rhinoplasty. The term non-Caucasian is used interchangeably to speak about patients of ethnic origin. It becomes important to understand the interplay of culture, race, and ethnicity when evaluating patients and defining what their aesthetic ideals are and what will be needed for surgery. An integrated approach and management of the non-Caucasian patient is presented in which medical and surgical options are explored. The final goal when treating non-Caucasian patients should be trying to help patients achieve their aesthetic ideal in the best possible fashion.

Rhinoplasty in the Older Adult

BACKGROUND

Rhinoplasty in older adults requires unique consideration of the aging nose.

OBJECTIVES

The purpose of this study was to systematically review the literature pertaining to rhinoplasty in the aging population, review the senior author's experience, and describe techniques aimed at addressing age-related features. It was hypothesized that consistent age-related nasal dysmorphology is described in the literature and standard rhinoplasty techniques may effectively address these changes. Furthermore, it was hypothesized that rhinoplasty is more commonly performed for posttraumatic and functional indications than for aesthetic reasons.

METHODS

A literature review including publications describing rhinoplasty in patients over 55 years old was conducted. Additionally, a retrospective review of the senior author's cases was performed. Pre- and postoperative photographs were used to compare anthropometric changes. Demographic factors, surgical indications, and operative details were collected.

RESULTS

Nine articles met the study criteria. Manifestations of the aging nose included soft tissue atrophy, bony fragility and resorption, tip ptosis, internal and external valve collapse, and worsening dorsal hump. Twenty-seven patients were included in this institutional review. Primary indication for rhinoplasty was posttraumatic deformity in 17 (63%) patients and nasal obstructive symptoms in 10 (37%) patients. Tip refinement and ptosis were addressed through tip grafts (70%), columellar struts (26%), and caudal septal extension grafts (67%). Nasal obstruction was relieved through septoplasty (96%), turbinate ablation (85%), and spreader grafts (70%).

CONCLUSIONS

This study presents a systematic review of rhinoplasty in the older adult as well as a retrospective review of the senior author's patients. Unique considerations specific to this population should be integrated into treatment planning.

Expanded Role of Alar Contour Grafts

SUMMARY

Alar rim deformities are among the most common problems affecting patients undergoing both primary and secondary rhinoplasty. They can be caused by several factors such as congenital hypoplasia or malpositioning of the lateral crura, and from acquired surgical weakening during rhinoplasty. Even though altering the structure of the lower lateral cartilage complex can help prevent and correct alar rim deformities, this may not always allow for sufficient control of the alar rim. Alar contour grafts have been proven efficacious not just in the treatment of specific rim deformities but also in their prevention. In this article, the authors present four types of alar contour grafts and discuss their expanded role in the prevention and treatment of alar rim deformities.

Comparative Effectiveness of Cartilage Grafts in Functional Rhinoplasty for Nasal Sidewall Collapse

Objective: To compare the patient-reported outcomes among patients with nasal obstruction undergoing two rhinoplasty techniques to a control group. Methods: Prospective longitudinal study in a university-based tertiary care medical center. All patients undergoing functional septorhinoplasty for correction of lateral wall insufficiency between October 2015 and March 2019 were included; n = 704, mean age (standard deviation) 39.0 (15.4) years, 52.7% females. Patients completed the Nasal Obstruction Symptom Evaluation (NOSE) and FACE-Q subscales pre- and postoperatively. Patients were divided into three cohorts: spreader and lateral crural strut (LCS) grafts (n = 141), spreader and alar rim (AR) grafts (n = 104), and the control spreader grafts alone (n = 218). Results: The median NOSE scores at last postoperative visit were improved from baseline (p < 0.001) for all cohorts. The FACE-Q nasal satisfaction median scores also improved postoperatively in all cohorts, AR, LCS, and spreader, respectively (p = 0.001, p < 0.001, and p < 0.0001). Conclusions: There was no detectable difference in the improved subjective nasal function, nor adverse aesthetic outcomes in the patients with lateral wall insufficiency treated with functional rhinoplasty techniques in this study.

A comprehensive analysis of the correction of alar retraction in rhinoplasty: A systematic review

BACKGROUND

Alar retraction, as a type of alar deformity, seriously affects the esthetic perception of the nose in patients. Despite the rapid development of rhinoplasty in recent years, the treatment of alar retraction is still a challenge work in plastic surgery. This systematic review highlights the etiology, treatment, and prevention of alar retraction to further guide practitioners.

METHODS

A systematic review was conducted from 1975 to 2020 through PubMed, Embase, Web of Science, and Cochrane database with the key words "alar retraction" and "rhinoplasty" or "Rhinoplasties" to investigate the surgical treatment of alar retraction. The inclusion and exclusion criteria were set to screen the literature.

RESULTS

A total of 163 literatures were obtained through database retrieval. After removing the duplicate literature, reading the title and abstract, and reviewing the full text finally, 34 articles were included in the final study. Most of the articles have summarized the surgical methods to correct alar retraction by retrospective study.

CONCLUSIONS

Alar retraction should be analyzed from the etiology, pathogenesis, and treatment. The diversity of surgical methods provides more options for the clinic. However, the plastic surgeons need to develop sharp analytical skills, improve clinical operational capability, and look for appropriate methods to achieve in good result.

Rotating the Tip in Long Noses: A Strategy rather than a Single Technique

Background:

Rhinoplasty is one of the most commonly performed aesthetic surgical procedures in plastic surgery, the incidence of which has increased up to approximately 1 million cases in 2016 according to the recent International Society of Aesthetic Plastic Surgery survey. This study aimed at defining the importance of each sequential procedure within the same surgery, the extent to which a procedure can be performed, and those that can be omitted.

Methods:

In this descriptive study, 27 candidates (18 women; nine men; age range, 20–48 years) for primary rhinoplasty between September 2016 and September 2019 were included. All had long noses, their main concern was reduction of nasal tip projection and all were seeking cranial tip rotation to enhance their tip aesthetics. Those who required revision rhinoplasty or who had nasal deformities due to congenital defects, and those older than 60 or younger than 18 years of age, were excluded.

Results:

The average nasolabial angle in women preoperatively was 88.2 ± 6.6 and postoperatively 102.8 ± 5.6. In men, the average average nasolabial angle preoperatively was 79.6 ± 5.4 and postoperatively 92.3 ± 2.3. In both men and women, the P value was <0.001, which indicates high significance. Tip rotation was achieved in all patients, with 81% achieving ideal rotation, and 19% exceeding the ideal range.

Conclusions:

Rotating the tip in long noses is a complex procedure. It can be achieved by many described techniques, but not all are required. A general strategy should be followed during which variable techniques, with varying efficacy, can be utilized.

The Harvest of a Lateral Segment of Costal Cartilage for Treating Nasal Deformities

BACKGROUND

Although costal cartilage has many uses and is a reliable source of cartilage for rhinoplasty procedures, donor-site complications may arise with conventional harvesting techniques. The present report reports a novel technique of harvesting costal cartilage using a specially designed scalpel and studies the use of the harvested cartilage in the reconstruction of secondary nasal deformities in patients with cleft lips.

METHODS

Ten patients (7 females and 3 males) with nasal deformities secondary to cleft lip underwent rhinoplasty using this new technique at the Department of Oral and Maxillofacial Surgery, Second Hospital of Hebei Medical University, China, between May 2011 and December 2013. Clinical outcomes were evaluated with a follow-up period of 6 to 30 months.

RESULTS

The new technique successfully corrected primary nasal deformities, including flat nasal tip, short columella, flaring alae, and asymmetrical nostrils. Surgeons and patients assessed the outcome to be either good or satisfactory. Patients experienced transient discomfort at the wound site but there were no major complications (such as wound infection, dehiscence, exposure, graft extrusion, and pulmonary involvement).

CONCLUSIONS

The novel technique can harvest a lateral segment of costal cartilage for use in the reconstruction of nasal deformities secondary to cleft lip in a one-stage procedure, with minimal donor-site morbidity.

Folded Cymba Concha: Is It Large and Stable Enough for Caudal Septal Extension Graft in Asian Rhinoplasty?

BACKGROUND

Septal extension grafting (SEG) is used for nasal tip projection and positioning. Often, insufficient quadrangular cartilage is available for grafting in Asians, and in most secondary cases the septum is already harvested. We utilized the folded cymba concha as an alternative for caudal SEG (CSEG) by modifying a tongue-in-groove technique.

OBJECTIVES

The aim of this study was to evaluate the physical suitability of the cymba concha for CSEG and compare its outcomes with those of septal quadrangular cartilage.

METHODS

The mean length and width of 311 harvested consecutive folded cymba conchae were measured from intraoperative photographs. Data from 220 patients with >12 months of follow-up were retrospectively reviewed for clinical outcomes. Clinical demography was determined based on the need for additional spreader grafts. For clinical reliability, anthropometric photographs of patients in whom folded cymba conchae were used were compared with those in whom quadrangular cartilage was used.

RESULTS

Mean [standard deviation] lengths and widths of the folded cymba conchae in men and women were 24.2 [3.9] and 22.4 [3.7] mm, and 7.8 [1.9] and 7.2 [1.9] mm, respectively. Use of the folded cymba concha graft significantly increased nasal tip projection by 28.9% and columellar-labial angle by 9.7%, improving both aspects postoperatively. Anthropometric comparison revealed no significant differences between folded cymba conchae and septal cartilage in terms of nasal tip projection (P = 0.264) and postoperative columellar-labial angle (P = 0.182).

CONCLUSIONS

Folded cymba conchal cartilage can be a primary option for CSEG in Asian septorhinoplasty cases or for individuals with insufficient septal cartilage remnants.

Revision Rhinoplasty: With Introduction of a Novel Preoperative Assessment Classification System

Revision rhinoplasty presents several complex surgical challenges. Proper patient selection for revision rhinoplasty, along with thorough preoperative examination and surgical planning, is key to achieving ideal outcomes. Along with achieving a high level of understanding of primary rhinoplasty techniques, surgeons performing revision rhinoplasty must understand and diagnose deformities created by the primary surgery. A systematic approach to diagnosing rhinoplasty deformities assists in forming a suitable surgical plan. A classification system based on nasal analysis, described here, may be used to differentiate the degree of difficulty of the surgery as well as assist in surgical planning. Surgeons have a multitude of options available in their armamentarium for addressing common nasal deformities encountered during revisional surgery, and a stepwise surgical approach may facilitate the creation of an optimal aesthetic and functional result.

Alar Flare Preservation Using the Sandwich Technique as an Adjunct to Alar Base Reduction

Achieving an aesthetic balance and natural appearance when modifying soft tissues of the nasal tip, alae, and nostrils is fundamental to the success of rhinoplasty surgery. The present study aimed to investigate the ability of a simple “sandwich” technique combined with external alar base reduction to preserve the alar flare and achieve a natural and appealing alar contour.

Caudal Extension Graft of the Lower Lateral Cartilage: Technique and Aesthetic and Functional Results

Here we describe a new technique to deal with alar retraction, a highly undesirable imperfection of the nose. The procedure involves placing a caudal extension graft below the vestibular portion of the lower lateral cartilage (LLC) after its detachment from the vestibular skin. The graft is fixed to the cartilage and, subsequently, to the vestibular tissue. The present retrospective study included 20 patients, 11 females and 9 males, with a mean age of 28.90 years. Follow-up ranged from 1 to 18 months. Surgery improved alar notching to a smoother dome shape and nostril exposure was reduced in every patient. The caudal extension graft of the LLC contributed to rise in overall patient satisfaction, as revealed by the postoperative increase of the Rhinoplasty Outcomes Evaluation (ROE) mean score from 40.0 to 79.17 (p < 0.0001). It also contributed to and improved functional outcomes, as indicated by the decrease of the Nasal Obstruction Symptom Evaluation (NOSE) mean score from 52.75 to 13.25 (p = 0.0001). Sex did not affect the mean ROE and NOSE scores. Thus, increased patient satisfaction measured by the ROE is present in both sexes and at both age groups but it is better detected in the first year after surgery. Functional improvements analyzed with NOSE are best detected in patients aged ≥ 30 years and in follow-ups of 11 months. The caudal extension graft of the LLC technique described herein effectively and safely corrects alar retraction and the collapse of the nasal valve while filling the soft triangle.

Posterior Cephalic Soft Triangle of the Nose: Surgical Implications

BACKGROUND

The posterior cephalic soft triangle is formed between the posterior cephalic border of the lower lateral cartilage, posterior caudal border of the upper lateral cartilage, and the caudal edge of the nasal bone. PCST is an important component of the external nasal valve which provides resistance against dynamic collapse.

OBJECTIVES

The objective of this study was to describe the anatomy of the PCST and to demonstrate its anatomic variations, dynamic interplays, and surgical implications.

METHODS

A retrospective review was conducted of 310 primary and 42 secondary cases who underwent extended open approach rhinoplasty by the first author. The structures that create the PCST of the nose were preserved unless resection/displacement of them was absolutely necessary. Whenever an external nasal valve pathology was found, it was corrected with one or combination of the following maneuvers: triangular PCST onlay graft, caudal bone outfracture, alar rim graft, lateral crural strut graft.

RESULTS

Twenty-four non-consecutive cases were identified in which PCST was intraoperatively confirmed to be weak or deformed. The most common pathology in the PCST was overresection of the posterior segments of the LLC during primary surgery (54.1%), followed by en bloc medialization of the PCST (33.3%). Triangular onlay grafting of the PCST was the most common corrective surgical intervention (83.3%), followed by corrective lateralization of caudal edge of nasal bone (29.1%). External valve function has been restored in 21 (87.5%) cases.

CONCLUSIONS

Cephalic lateral crural advancement flap

Background

In lower lateral cartilage (LLC) surgery, cephalic trimming poses risks for the collapse of the internal and external nasal valves, pinched nose, and drooping deformity. The cephalic lateral crural advancement (CLCA) technique presented herein was aimed at using a flap to increase nasal tip rotation and support the lateral crus, in addition to the internal and external nasal valves, by avoiding grafts without performing excision.

Methods

This study included 32 patients (18 female and 14 male) and the follow-up period for patients having undergone primer open rhinoplasty was 12 months. The LLC was elevated from the vestibular skin using the CLCA flap. A cephalic incision was performed without cephalic trimming. Two independent flaps were formed while preserving the scroll ligament complex. The CLCA flap was advanced onto the lower lateral crus while leaving the scroll area intact. The obtained data were analyzed retrospectively.

Results

The mean age of the patients was 31.6 years (range, 20–51 years). The Rhinoplasty Outcome Examination scores after 12 months varied from 90 to100 points, and 93% of patients reported perfect satisfaction. At a 1-year follow-up, the patients’ nasal patency (visual analogue scale) rose from 4.56±1.53 (out of 10) to 9.0±0.65 (P<0.001).

Conclusions

The CLCA flap led to better nasal tip definition by protecting the scroll area, increasing tip rotation, and supporting the internal and external nasal valves without cephalic excision.

Avoiding Complications in Functional and Aesthetic Rhinoplasty

Historically, nasoseptal surgery favoring functional considerations has compromised aesthetic ones, and vice versa, but modern techniques have evolved that allow symbiotic achievement of both goals. Nasoseptal surgery is among the most commonly performed plastic surgical procedures in the United States, and while it is generally well tolerated, there are a few surgical and aesthetic complications of which to be aware. Herein, we review surgical techniques that improve the nasal airway and nasal aesthetics in a top-down approach with a discussion of possible ensuing complications.

A New Graft Technique For Rhinoplasty: Modified One-Piece Nasal Cap With Alar Strut Graft

OBJECTIVES

This study was aimed to evaluate the effectiveness of the new graft technique-modified one-piece nasal cap with alar strut graft in rhinoplasty; both for aesthetical appearance and nasal functions.

METHODS

Forty-two patients, who underwent primary rhinoplasty operation with the new graft technique, were evaluated visually by photographing and functionally by the Cottle test and rhinomanometry measurement.

RESULTS

All of the patients had sufficient nasal vision; also nasal valve angles became wider and Cottle tests were negative in all patients after surgery. Postoperative nasal airflow values (both left and right) were significantly higher, and airway resistance (left, right, and total) values were significantly lower than preoperative values.

CONCLUSION

With the new graft technique, the authors obtained both satisfying aesthetic results and intended functional improvement. This technique may be an alternative to combination of multiple graft techniques; with advantages of practical performing and less complication risks.

Defining the Histologic Support Structures of the Nasal Ala and Soft Triangle: Toward Understanding the Cause of Iatrogenic Alar Retraction

BACKGROUND

As rhinoplasty techniques have evolved to more extensive dissections, the incidence of iatrogenic deformities, such as alar rim retraction, has risen. Its mechanism is presently unknown. This study examined the microscopic anatomy of the nasal ala to define architectural support elements at the histologic level to determine why rhinoplasty dissection creates such deformities.

METHODS

Eight cadaveric noses were harvested and sectioned through the soft triangle and ala. Various tissue stains were performed. Slides were examined using light microscopy. Anatomical features pertaining to cartilage, skin, mucosa, elastic fibers, and muscle were documented.

RESULTS

Four male and four female noses were sectioned. The median cadaver age was 64 years (range, 47 to 83 years). On Elastica van Gieson stain, distinct elastic fibers span from the vestibular lining to the caudal margin of the lower lateral cartilage, and from the caudal edge of the lower lateral cartilage to the external alar skin. In the nasal ala midsection, trichrome stains reveal that skeletal muscle is located far beyond the lower lateral cartilage, close to the free alar margin. The soft triangle shows a distinct microanatomical structure, with heavy longitudinal condensations of elastin. These histologic findings have not been previously reported.

CONCLUSIONS

A distinct anatomical alar wall endoskeleton has been identified. It is obligatorily disrupted by specific rhinoplasty maneuvers when dissection is carried out over the lateral crura and into areas without cartilaginous support. This microanatomy may explain factors that contribute to postoperative alar wall retraction. Leaving this area undisturbed or performing adjunctive measures with rhinoplasty can provide structural support to the external valves, thus minimizing the risk of deformity.

Mono-Unit Alar Rim Graft Technique for Tip-Alar Margin Support

BACKGROUND

The appropriate treatment of alar rim deformities, such as alar pinching or concavity, and soft triangle notching is essential for perfecting nasal aesthetics.

OBJECTIVES

The authors introduced the "mono-unit alar rim graft" technique as a treatment option for these abnormalities.

METHODS

A case series of 29 rhinoplasties conducted by the senior author between May 2017 and June 2019 utilizing the mono-unit alar rim graft technique was retrospectively reviewed. The surgical technique involved an open approach with costal cartilage harvesting. The cortical portion of the harvested costal cartilage was sectioned into a 1-mm-thick strip and soaked with saline for about 15 minutes to let the natural warping occur. The curved cartilage graft was then trimmed, and the midportion was sutured to the tip in an onlay fashion. Both ends of the graft were housed in the vestibular pocket. Patient demographic data and pre- and postoperative facial photos were reviewed.

RESULTS

Among the 29 cases analyzed, 14 (48.3%) were men and 15 (51.7%) were women. Ten (34.5%) patients had a preoperative parenthesis deformity, but a near-complete correction was achieved in 8 (80.0%) cases. An alar concavity from the basal view was found in 16 patients, 15 (93.8%) of whom had a partial or near-complete correction. Eleven patients had soft triangle notching, 9 (81.8%) of whom had a partial or near-complete correction. There were no technique-related complications in this patient series.

CONCLUSIONS

The mono-unit alar rim graft technique is a viable option for treating various alar rim deformities.

Rhinoplasty Refinements: Addressing the Deviated, Overprojected Nose

Deprojection of an overprojected nose and correction of an infralobular deformity are very challenging for rhinoplasty surgeons because a systematic approach is needed to correct these problems. A deviated nose with a dorsal hump is a common deformity that is best treated using septal reconstruction and the component dorsal hump reduction technique using an open rhinoplasty approach. This article and its videos show how to correct a deviated nose with overprojection and a dorsal hump deformity.

The Keystone, Scroll Complex, and Interdomal Area of the Nose: Histologic and Anatomical Observations

Comprehensive knowledge of nasal anatomy is essential for obtaining aesthetically and functionally pleasing results in rhinoplasty. In this study, the authors described the anatomy, histology, and clinical relevance of the interdomal region, keystone, and scroll complex. The current study examined these areas in 26 fresh cadaver heads. All cadavers were fresh, and no conservation or freezing processes were applied. All dissections were performed by the first author. It was determined that the structure that connected the middle crura in the interdomal region actually came together in the transverse plane and contained abundant capillaries within. It was observed that chondroblasts with high regenerative potential were present in the keystone area, and there was very tight attachment between periosteum and perichondrium. The scroll complex was found to be more flexible and thin and had fewer regenerative cells compared to the keystone region. With its unique anatomy and histology, the keystone acts as a transition area between the flexible and fixed units of the nose. The scroll complex should be taken into consideration during rhinoplasty because of its effects on fixation of the skin in the lateral supratip area and functional effects on internal and external nasal valves. The interdomal ligament, in contrast, acts as a transition between both middle crura rather than a real ligament.

Rhinoplasty Using Three-Dimensional Analysis and Simulation

Treatment of nasal deformity and obstruction requires analysis, planning, and precise execution of rhinoplasty techniques. When performed well, rhinoplasty is a powerful tool for achieving appealing nasal morphology and optimizing function. This article aims to highlight an open approach to septorhinoplasty using a number of techniques that are preferred by the senior author (D.M.S.) to successfully correct a congenital nasal deformity and deviated septum.

Updated Dynamics of Rhinoplasty: A Review of the Literature and Comprehensive List of the Findings

BACKGROUND

The cardinal reason accounting for the complexity of rhinoplasty is that each maneuver during this operation has both intended and unintended effects. The purpose of this report is to review the literature and update the dynamics of rhinoplasty.

METHODS

PubMed searches were conducted for "rhinoplasty dynamics" as well for keywords associated with each specific rhinoplasty maneuver. Titles were evaluated for relevance, and duplicates were consolidated with years of publication 1991 to 2019. Article types include case series (retrospective and prospective), cohort studies, and review articles.

RESULTS

Beginning with the radix, its reduction apparently elongates the nose and widens the intercanthal space, while radix augmentation creates the opposite illusions. In a similar manner, dorsal hump reduction widens both the nose and intercanthal space. Nasal tip dynamics focus on the aftermath of changes to tip projection, width, and rotational position. Resection of the upper lateral cartilages can cephalically rotate the tip and reduce tip width. Manipulation of the footplates of the medial crura primarily influences the columella but can also affect tip projection. Placement of a columellar strut firmly establishes tip position. Placement of alar rim grafts advances the ala caudally, widens the nostrils, and elongates the short nostril. Alar base reduction can create the illusion of increased tip projection. Augmentation and reduction in the anterior nasal spine influence tip projection, upper lip length, and the nasolabial angle.

CONCLUSIONS

As rhinoplasty techniques continue to evolve, surgeons undertaking this operation must continue to reassess the dynamics of various maneuvers.

Developing Consistency in Rhinoplasty

This invited Special Topic article outlines the authors' evolution and technique to optimize consistent results in rhinoplasty.

Changing Role of Septal Extension versus Columellar Grafts in Modern Rhinoplasty

Effective control of nasal tip projection and rotation is a key component in modern rhinoplasty. Tip projection is a product of several anatomical factors: length and strength of lower lateral cartilages, the suspensory ligament, fibrous connections to the upper lateral cartilages, and the anterior septal angle. Several cartilage grafts have been described for effectively altering nasal tip projection and rotation. Columellar struts and septal extension grafts are both commonly used in modern rhinoplasty to affect projection and rotation of the nasal tip. Although columellar strut grafts have shown moderate efficacy in maintaining tip projection and unifying the tip complex, their effect on increasing tip projection has been shown to be very limited. In comparison, septal extension grafts have been shown to effectively control tip projection, rotation, and shape by securing the nasal tip to the septum. Varieties of septal extension grafts have been described to support the medial crura and control tip shape, all of which depend on the presence of a stable caudal septum. The type of graft used is dependent on the specific characteristics of the underlying tip structures. The authors' aim is to provide an updated classification of cartilage grafts for altering nasal tip projection and rotation, and an algorithmic approach for their implementation. Although both columellar struts and septal extension grafts offer the modern rhinoplasty surgeon a way to alter tip projection and rotation, they do vary in efficacy. Understanding which graft to use and in what setting is key in successfully controlling projection, rotation, and shape of the nasal tip.

Functional Outcomes, Quantitative Morphometry, and Aesthetic Analysis of Articulated Alar Rim Grafts in Septorhinoplasty

Importance

The design, use, and indications for the articulated alar rim graft (AARG) and the functional and aesthetic improvements that can be achieved have not been fully characterized.

Objective

To analyze the functional and aesthetic outcomes of AARG placement on nasal airway function, nasal base shape change, and appearance.

Design, Setting, and Participants

A case series study of patients who underwent septorhinoplasty with placement of AARG at University of California, Irvine Medical Center, from 2015 to 2018 was carried out. Surgical data recorded included stage of rhinoplasty (primary vs revision), use of spreader grafts, rim grafts (and dimensions), caudal septal extension graft (CSEG), lateral crural tensioning (LCT), and turbinate reductions.

Main Outcomes and Measures

Preoperative and postoperative Nasal Obstruction Symptom Evaluation Survey (NOSE) surveys were analyzed and correlated with AARG geometry, use of CSEG, and the LCT maneuver. Preoperative and postoperative alar base views were evaluated by fitting base shape to a parametric numerical model to categorize each to 1 of 6 shape categories. Blinded reviewers rated alar furrow severity and the alar ridge presence using a Likert scale for both preoperative and postoperative images to subjectively gauge aesthetic outcomes.

Results

Overall, 90 patients with both preoperative and postoperative NOSE scores who underwent septorhinoplasty and placement of an AARG were included. Of the 90 patients, 60 were women (mean age, 38.2 years). Patient NOSE scores (70.4 preoperatively to 25.1 postoperatively) significantly improved from preoperation to postoperation (P < .001), regardless of AARG size, CSEG, or LCT. Alar base shape parametric analysis showed preoperative to postoperative improvements were significant for anterior-to-posterior ratio mass distribution (95% CI, -0.16 to 0.02; P = .05) and vertical projection-to-horizontal base width ratio (95% CI, 0.01-0.32; P = .02) in flat noses and cloverleafing for narrow noses (95% CI, -0.05 to -0.01; P = .001); enhancement approached significance for reduction in lateral scalloping in cloverleaf noses (P = .06). Aesthetic analysis showed that there was a statistically significant improvement for the alar furrow (95% CI, -0.68 to -0.29 for rater 1; -0.54 to -0.27 for rater 2; and -0.59 to -0.27 for rater 3; P < .001) for all raters and for the alar ridge (95% CI, 0.16-0.48; P < .001) for 1 rater.

Conclusions and Relevance

To our knowledge, this is the first study to demonstrate that AARG use is associated with statistically significant improvement in NOSE scores. Placement of AARGs may improve posterior mass ratios in flat noses and lateral cloverleafing in narrow noses as suggested by quantitative shape change parameter analysis. The placement of AARGs was associated with aesthetic and functional enhancement in the cloverleaf deformity, which is associated with a prominent alar furrow, and often external nasal valve collapse. Patient selection is key when placing AARGs.

Revisiting the Alar-Columellar Relationship: Classification and Correction

The alar-columellar relationship has tremendous aesthetic significance in the lower one-third of the nose. Aberrancies in the alar-columellar relationship detract from nasal aesthetics, and are classified into six types: type I, hanging columella; type II, retracted ala; type III, combination of a hanging columella and retracted ala; type IV, hanging ala; type V, retracted columella, and type VI, combination of a hanging ala and retracted columella. This article describes the methods for proper evaluation and diagnosis of aberrancies in the alar-columellar relationship, and current strategies to restore the ideal alar-columellar relationship.

Primary Open Rhinoplasty

LEARNING OBJECTIVES

After studying this article and viewing the videos, the participant should be able to: 1. Describe the operative technique necessary to perform open rhinoplasty. 2. Summarize the steps necessary in performing a component dorsal reduction. 3. Develop a surgical plan for nasal tip shaping and cephalic rotation of the nasal tip. 4. Identify the need for aesthetic improvement of the alar base, and perform successful alar base surgery. 5. Demonstrate consistency, safety, and predictability in rhinoplasty.

SUMMARY

Rhinoplasty remains one of the most challenging procedures in plastic surgery, and continues to be one of the top five aesthetic surgical procedures, with over 223,000 performed in 2016. Rhinoplasty may be performed by means of the "open" or the "closed" approach, and each approach has its advantages and disadvantages. This article focuses on the open approach, and the principles and techniques necessary to achieve consistent and gratifying results. As with all plastic surgery procedures, successful rhinoplasty begins with a thorough clinical analysis, definition of the goals, meticulous preoperative planning, precise operative execution, vigilant postoperative management, and a critical analysis of one's results.

Vertical Alar Folding (VAF): A Useful Technique for Correction of Long and Concave Lateral Crura in Rhinoplasty

BACKGROUND

The tripod theory explains the dynamics of the nasal tip, where surgery is difficult because of anatomic variations and pathologies and the various surgical possibilities. Abnormalities or weaknesses of the lateral crura can result in concavity in ala or alar collapse and cause aesthetic and functional impairments of the nose. Several tip plasty techniques and lateral crura modifications are used in rhinoplasty.

OBJECTIVE

To describe the vertical alar folding (VAF) technique for making modifications in the lateral crura (LC) and rotation of the tip.

METHODS

Included in the study were 83 patients (59 women, 24 men) undergoing rhinoplasty using VAF with the senior author as surgeon between 2013 and 2018. The mean age was 26.3 years (range 18-47). Mean postoperative follow-up period was 26.7 months (range 12-64). Patients who completed the 1-year postoperative period completed the rhinoplasty outcome evaluation (ROE) questionnaire. Outcome measures were performed at examinations, and preoperative and postoperative photographs of the patients were analyzed.

RESULTS

In the span of 5 years, no revision surgery was required for technique-specific reasons. In patients who had a droopy or asymmetric tip or long and concave lateral crura, we saw remarkable functional and aesthetic improvements with VAF. According to the ROE questionnaire, 90.3% (75 out of 83) of the patients were content with the aesthetic and functional results.

CONCLUSION

VAF is a useful and effective method for modifying the LC and tip of the nose. VAF allowed for controlling the rotation and projection of the tip, changing the length of the lateral crus and nose with durability and smooth, symmetric contours, and correcting concavity of a lateral crus for better functioning and aesthetics.
