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

Repair of Lateral Wall Insufficiency

Importance

Lateral wall insufficiency (LWI) is classified by the zone in which it occurs. Multiple techniques for treating LWI are described in the literature and are used, but no treatment approach has been widely adopted.

Objective

To establish an algorithm for treatment of LWI by evaluating subjective and objective outcomes of patients who underwent LWI repair and comparing these results with those of a control group who received no specific LWI repair.

Design, Setting, and Participants

This case-control study was conducted in a tertiary referral center. In group 1, there were 44 patients who underwent septorhinoplasty to repair LWI between February 1, 2014, and May 31, 2016. In group 2, there were 44 age- and sex-matched patients who underwent cosmetic septorhinoplasty without LWI repair. Data analysis was conducted from February 1, 2014, to May 31, 2016.

Intervention

Open septorhinoplasty.

Main Outcomes and Measures

Nasal Obstruction Symptom Evaluation (NOSE) scores and LWI grades.

Results

Forty-four patients (8 men and 36 women, with a mean [SD] age of 46 [16] years) who underwent open septorhinoplasty to repair LWI and 44 age- and sex-matched patients (composed of 8 men and 36 women, with a mean [SD] age of 41 [12] years) were included in the study. The mean (SD) preoperative NOSE scores were 69.4 (22) in group 1 and 20.5 (20.8) in group 2 (P < .001). The NOSE scores in both groups significantly improved after surgery (44.7 [95% CI, -28.9 to -49.9; P < .001] and -14.5 [95% CI, -2.7 to -18.5; P = .02]), although the improvement in group 2 was not clinically significant. The mean preoperative LWI grades were higher in group 1 than in group 2 for each zone (P < .001 and P = .001) but were similar between groups for each zone after surgery. Postoperative LWI scores significantly decreased in group 1 to levels similar to that of group 2. A positive linear correlation was noted between NOSE scores and LWI grades, with the strongest correlation between preoperative zone 1 LWI grades and NOSE scores (R = 0.68). Lateral crural strut grafts were used for zone 1 LWI and alar rim grafts were used for zone 2 LWI.

Conclusions and Relevance

The LWI grading system enables surgeons to localize LWI, tailor the surgical treatment to the patient, and monitor improvements in the postoperative period.

Postsurgical Alar Retraction: Etiology and Treatment

The cephalic trim technique is a popular maneuver that often leads to tip deformities, most notably postsurgical alar retraction (PSAR). We advocate using the external rhinoplasty approach to correct PSAR by (1) releasing and repositioning the retracted alar margin, (2) strengthening and immobilizing the central tip complex using a septal extension graft, (3) suspending and longitudinally tightening the mobilized lateral crural remnant by adjusting crural length to match the sidewall span, and (4) providing direct skeletal support to the repositioned alar margin using articulated alar rim grafts. Using this structural treatment paradigm, we have corrected severe PSAR in the preponderance of secondary rhinoplasty cases.

Correction of Nasal Pinching

The pinched nasal tip deformity often results as sequelae of prior nasal surgery. Conventional tip surgery techniques that overemphasize tip narrowing often deform the lateral crura and weaken support for the alar margin. The pinched nasal tip is characterized by the demarcation between the nasal tip and the alar lobule, isolating the tip from the surrounding nasal subunits. Lateral crural strut grafts with or without repositioning offer the surgeon a powerful maneuver that can help correct this functional and aesthetic deformity and restore a natural appearance to the nasal tip.

Component Restoration in the Unilateral Intermediate Cleft Tip Rhinoplasty: Technique and Long-Term Outcomes

BACKGROUND

The intermediate cleft tip rhinoplasty is performed in childhood to address residual tip asymmetries during the most critical period of psychosocial development. The authors describe and evaluate long-term outcomes of that approach for the unilateral cleft lip and palate patient based on the concept of individual restoration of each abnormal anatomical component.

METHODS

Photomorphometric analyses of unilateral cleft lip and palate patients (n = 50) who underwent intermediate cleft tip rhinoplasty using the component restoration technique were evaluated preoperatively (time 0) and postoperatively at less than 1 year (time 1), 1 to 3 years (time 2), and more than 3 years (time 3) and compared to age-matched unilateral cleft lip and palate control patients. Nasal relationships (alar symmetry, nasal tip protrusion-to-alar base width ratio, and height-to-width dimensions for the cleft and noncleft nostrils) were compared over time using a linear mixed-effect model.

RESULTS

At time 0, both groups demonstrated similar nasal relationships, with the exception of a wider cleft-side nostril in relationship to height in the rhinoplasty group. The component restoration technique improved all four nasal relationships at all postoperative time points compared with time 0 in a statistically significant manner, whereas control patients did not demonstrate significant changes at the corresponding ages. Long-term differences at time 3 revealed a trend toward improved alar symmetry and cleft-side and non-cleft-side nostril dimensions, and a significant improvement in the nasal tip protrusion-to-alar base width ratio in intermediate cleft tip rhinoplasty-treated versus control patients (p = 0.002).

CONCLUSION

The component restoration technique for the unilateral intermediate cleft tip rhinoplasty improves nasal relationships toward normal immediately and in a sustained manner for at least 3 years.

Algorithm for the treatment of external nasal valve insufficiency

Introduction

Nasal obstruction is one of the most prevalent complaints in the population. The main causes of nasal obstruction are inflammatory, infectious or anatomical alterations. Anatomical alterations include nasal septum deviation, turbinate hypertrophy, and nasal valve insufficiency (external and/or internal). The diagnosis of nasal valve insufficiency remains a clinical one and is based on inspection and palpation of the nose, evaluating both its static and dynamic functions. The literature presents several options for the correction of external nasal valve insufficiency. These are chosen according to the choice and experience of each surgeon.

Objective

To create a practical algorithm for the treatment of external nasal valve insufficiency that can guide nasal surgeons in their choice of treatment for the different anatomical alterations found in patients with these disorders.

Methods

We used the treatment options found in the literature and correlated them with our surgical options for each type of anatomical alteration found. Therefore, we used basically three parameters related to physical examination findings (degree of insufficiency and characteristics of the lower lateral cartilage) and the patient's complaint (present or absent aesthetic complaint regarding the nasal tip).

Result

A practical algorithm was developed for the treatment of external nasal valve insufficiency according to the degree of insufficiency (mild-to-moderate or severe), aesthetic complaint of the nasal tip (present or absent) and characteristics of the lower lateral cartilage (size and orientation).

Conclusion

Through this simple algorithm, one can use each type of graft and/or maneuver according to the patients’ complaints and the anatomical alterations found.

Cephalic Rotation of the Nasal Tip

The position of the nasal tip holds important aesthetic significance. Cephalic rotation of the nasal tip is a frequent motivating factor for patients seeking rhinoplasty. The position of the nasal tip is a complex interplay of the size, morphology, and position of several anatomical components of the lower one-third of the nose. Cephalic rotation can be achieved by means of six different methods. The indirect methods promote passive cephalic rotation and include cephalic trim of the lower lateral cartilages, caudal trim of the upper lateral cartilages, and caudal septal trim. Direct methods involve precise repositioning of the domes and include shortening the lateral crura, lateral domal relocation, and the tip rotation suture. Used alone or in combination, these techniques and their subtle variations represent comprehensive and effective methods to achieve cephalic rotation of the nasal tip.

The Relation Between the Lower Lateral Cartilages and the Function of the External Nasal Valve

INTRODUCTION

The position of the lower lateral cartilages (LLC) is closely related to the function of the external nasal valve (ENV). When there is a cephalic malposition of these cartilages, the nasal alae have inadequate support, which leads to ENV insufficiency during deep inspiration.

METHODS

Retrospective study with 60 patients evaluated: the positioning of the LLC and the occurrence of ENV insufficiency; the effectiveness of structuring the medial and lateral walls of the ENV; and the frequency of the grafts used for structuring it.

RESULTS

Of the 60 operated cases, 37 patients (62%) had ENV insufficiency, in 23 cases there was cephalic malposition of the LLC, and in the latter group 17 patients (74%) presented this insufficiency. A structured ENV was effective in the treatment of this insufficiency (p = 0.001). A lateral crural strut graft was performed in 24 cases (40%) of 60 patients operated. The alar contour graft was performed from 2013 to 2015 in 4 patients (22%) of 18 cases operated, and between 2016 and 2018 it was performed in 29 patients (69%) out of 42 cases. The columellar strut was routinely used from 2013 to mid-2016 in 33 cases (100%), and after that period until the present day the tongue-in-groove technique was performed in 11 cases (41%) and in the remaining 16 cases (59%) the caudal septal extension graft was performed.

CONCLUSION

Cephalic malposition of the LLC is an important red flag of ENV insufficiency. This insufficiency should be treated by structuring the walls of the ENV.

An Innovative and Easy Dome Holding Technique for Transdomal Suture in Rhinoplasty

Suture tip plasty is one the most used methods in nasal tip surgery. Transdomal suture (TDS) used for this purpose is utilized for providing the dome symmetry, thinning the nasal tip, and enhancing the nasal tip projection and rotation. However, there are not sufficient visual data on what the dome position should be during TDS. In this study, it was aimed to be directive in tip plasty and to define the convenient dome holding technique during TDS. Patients, 510 male and 621 female at the age of 18 to 50 years, who underwent the open technique septorhinoplasty between the years of 2003 to 2015 were included in the authors' study. The length of the patient follow-up varies between 1 and 10 years. Patients, on which the lateral crural strut graft was used and which underwent dome division/vertical dome division in tip surgery, and patients who were diagnosed with the alar cartilage asymmetry and underwent dome excision for any pathological reason to demonstrate the effectiveness of the TDS holding technique. During the TDS, the dome area was administered with 5/0 polydioxanone by being held at an angle close to the cranial in the posterior and the caudal in the anterior with a dentated forceps. In this study according the authors' pre and postoperative conclusions, the authors consider that this is a sufficient visual data on what the dome position should be during TDS by presenting video.

Middle Eastern Rhinoplasty: Update

Middle Eastern rhinoplasty requires especially precise preoperative planning to achieve a successful result. Among all aesthetic surgery procedures, there is a higher demand for rhinoplasty among Middle Eastern cultures. The key is to maintain the ethnicity of the patients while meeting their goals. In this brief overview, common features in Middle Eastern patients and Middle Eastern rhinoplasty techniques in men and women are highlighted.

Nasal Tip Grafts

OBJECTIVES

The nasal tip is the most prominent part of the nose. The aim of this paper is to review nasal tip grafts with detailed explanation and figures.

METHODS

The authors searched PubMed, Google, Google Scholar, and Proquest Central database of the Kirikkale University. Search was performed with the key words of "nasal," "tip," "graft." The indications and grafting techniques were presented.

RESULTS

The external shape of the nasal tip is determined by the curves and contours of the lower lateral cartilages and their interactions with the surrounding tissues. Normative data exist regarding the ideal shape and shadowing of the nasal tip. The mainly used tip grafts in rhinoplasty are "Floating graft (Goldman) ," "Tip Onlay Graft," "Columellar Strut Graft," "Caudal Septal Extension Graft," "Shield Graft," "Alar batten onlay graft," "Lateral Crural Strut Grafts," "Alar rim grafts."

CONCLUSION

When tip sutures are not enough, cartilage tip grafts offer a versitile and effective way to change the nasal tip. While there has been a vast array of grafting techniques described, this paper reviewed many of the most popular and useful grafts in modern use.

The impact of surgical manipulation on lower lateral cartilage stiffness

BACKGROUND

Cephalic trimming of the alar (or lower lateral) cartilage may cause weakening leading to external nasal valve collapse. Numerous methods have been proposed to combat this weakening in order to maintain lateral crural stiffness. The purpose of this study was to quantify the effect of mucosal stripping, cephalic trimming, cephalic turn-in flap, and lateral crural strut grafting on lateral crural stiffness.

METHODS

In situ cyclic compressive loading was performed on eight lateral crura in 4 fresh frozen cadaveric specimens. Testing was performed on the unaltered degloved cartilage (intact) and following each of the following interventions: mucosal stripping, cephalic turn-in flap, cephalic trimming, and lateral crural strut grafting. Linear regression of the generated force-displacement curves was used to calculate stiffness. Each intervention was compared to the intact cartilage.

RESULTS

Alar cartilage of all of the specimens demonstrated a linear response to compressive loading. Intact cartilage had a mean stiffness of 3.53 N/mm. Mucosal stripping and cephalic turn-in flaps yielded similar stiffness values to intact cartilage. Cephalic trimming reduced stiffness in all cases by a mean of 1.09 N/mm (p = 0.003). Lateral crural strut grafting significantly increased stiffness by a mean of 3.67 N/mm (p = 0.0001).

CONCLUSIONS

Cephalic trimming leads to decreased lateral crural stiffness in cadaveric specimens. Cephalic turn-in flaps restore pre-trimmed stiffness, and lateral crural strut grafting increases overall stiffness of the cartilage. These findings should be considered in patients undergoing rhinoplasty, particularly if there are concerns regarding potential external valve collapse.

The Infratip Lobule Butterfly Graft: Balancing the Transition from the Tip Lobule to the Alar Lobule

The nasal alae and the soft-tissue triangles are delicate structures, the contours of which are largely dependent on soft tissue and the indirect influence of the lower lateral cartilages. Creating appropriate and continuous contour from the tip lobule to the alar lobule can be challenging. The alar contour graft is one reliable method of achieving predictable contour. However, alar contour grafts of ideal length may be scarce. The butterfly graft is a simple, reliable, and predictable method of providing support in the region of the soft triangle, and spans the region between the tip lobule and alar lobule, thereby balancing the transition between these regions.

Nasal Obstruction Considerations in Cosmetic Rhinoplasty

Cosmetic rhinoplasty is an increasingly popular procedure in the United States. There are critical aspects of preoperative planning and intraoperative execution that facilitate successful rhinoplasty. Thorough preoperative assessment of the structures comprising the internal and external nasal valves and identification of potential at-risk areas for static or dynamic compromise must be done before surgery. Thoughtful maneuvers and meticulous surgical technique must be used. Postoperative counseling ranges from simple reassurance to medical therapy to procedural efforts to alleviate a patient's concerns. It is important to establish rapport with the patient and dutifully address all cosmetic and functional concerns.

Cutting the Holy Dome: The Evolution of Vertical Alar Resection

INTRODUCTION

Dome division or vertical dome division (VDD) is a tip plasty technique that is effective when applied appropriately to suitable patients. For 15 years, we have used VDD and made modifications as needed. In classical VDD, the dome area is cut and left to heal, but experience shows that additional components are needed to complement dome division, such as sutures or grafts. In this study, we retrospectively analysed our rhinoplasty patients in whom we used vertical alar resection (VAR) to assess the advantages and disadvantages of this technique. To our knowledge, this is one of the most exhaustive studies of VDD, including over 3000 patients.

MATERIALS AND METHODS

This retrospective case series reviewed the charts of 3965 patients who underwent VAR between 2000 and 2015. All patients were operated on by the senior surgeon. Dome division was used for various reasons, including a deformed tip area in revision rhinoplasties, droopy nose, wide tip, pinched nose, tip asymmetry, and overprojected nasal tip. Patients were excluded if they had septal deviation that enabled tip rotation, or a dorsum problem that caused tip asymmetry.

RESULTS

The study included 3965 patients (3172 women and 793 men) who underwent open rhinoplasty from 2000 to 2015. The mean patient age was 28.3 years (range 18-50 years). The mean clinical follow-up duration was 11.2 years.

CONCLUSION

In conclusion, this technique is capable of modifying all parameters of the nasal tip (projection, rotation, and volume), as required, at the same time, addressing many tip problems.

Association of Skin Thickness With Alar Base Reduction in Patients Undergoing Lateral Crural Repositioning and Strut Grafting

IMPORTANCE

Knowing the operation plan is important for rhinoplasty surgeons to prevent unpredictable results.

OBJECTIVES

To investigate the frequency of alar base resection in patients with different skin thickness who underwent lateral crural repositioning and lateral crural strut graft and to evaluate the results in the context of the current literature.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective case series study included 621 patients who underwent primary open septorhinoplasty by the same surgeon between January 1, 2012, and June 30, 2015. From the surgical notes, operation type (lateral crural repositioning [LCrep] with lateral crural strut grafting [LCSG] and with or without alar base resection) and skin type were recorded. Study participants' skin types were determined intraoperatively and divided into 3 groups: (1) thick skin (the tip definition was limited by skin thickness and subcutaneous tissue), (2) thin skin (the tip cartilage was visible and could be observed despite overlying soft tissue and skin), and (3) normal skin (the tip cartilage during the procedure had no effect on the tip definition).

MAIN OUTCOMES AND MEASURES

The rate of alar base resection according to the type of operation performed and patient skin thickness.

RESULTS

Of the 621 patients in the study, 95 (15.3%) were men and 526 (84.7%) were women. Lateral crural repositioning with LCSG was performed in 319 surgical procedures (51.4%), and alar base reduction was performed in 329 (53.0%). The rate of alar base resection differed significantly on the basis of whether LCrep with LCSG was performed (odds ratio [OR], 1.82; 95% CI, 1.32-2.50; P < .001). In patients with thin skin, there was no significant difference in the incidence of alar base resection associated with LCrep with LCSG (OR, 2.034; 95% CI, 0.912-4.539; P = .08). In patients with thick skin, a significant difference in the frequency of alar base resection was associated with the application of LCrep with LCSG (OR, 1.995; 95% CI, 1.228-3.241; P = .005). In patients with normal skin, LCrep with LCSG had no significant association with the frequency of alar base resection (OR, 1.557; 95% CI, 0.930-2.607; P = .09).

CONCLUSIONS AND RELEVANCE

The necessity of alar base reduction after LCrep with LCSG is greater in patients with thick skin than in patients with thin and normal skin. This study is the first to our knowledge to examine this topic in rhinoplasty.

Extended Alar Contour Grafts: An Evolution of the Lateral Crural Strut Graft Technique in Rhinoplasty

Modification of the lower lateral cartilage complex is the sine qua non of modern rhinoplasty, and the open approach to rhinoplasty has expanded the number of techniques available to help achieve an aesthetically pleasing tip. The ideal tip has been described as having a diamond-shaped configuration, with the lateral points formed by the tip-defining points, the superior point by the supratip, and the inferior point by the columellar break point. Over the years, various techniques have been described to minimize isolation of the tip and to help achieve the ideal tip configuration: lateral crural strut grafts, alar contour grafts (i.e., rim grafts), alar strut grafts, subdomal grafts, and suturing techniques such as alar flaring sutures. The authors present their technique of the extended alar contour graft, which represents an evolution of the lateral crural strut graft and its marriage with the alar contour graft. Lateral crural abnormalities do not usually occur singularly, but rather are the result of an interplay of several factors. Nevertheless, the recurring theme of orientation and alar support to prevent isolation of the tip by extended alar grooves remains. Extended alar contour grafts are a versatile technique to optimize tip shape and orientation by combining the many positive attributes of lateral crural strut grafts and alar contour grafts.

Finesse in Nasal Tip Refinement

Nasal tip refinement is one of the most difficult aspects of rhinoplasty surgery. In this article, the senior author (R.J.R.) presents his technique for nasal tip analysis and identifies the factors that contribute to nasal tip shape. Various techniques for nasal tip modification using both sutures and soft cartilage grafts are described to help produce optimal results.

Comparative Study of Functional Nasal Reconstruction Using Structural Reinforcement

Importance

Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support.

Objective

To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits.

Design, Setting, and Participants

This study was a retrospective review of the medical records of 190 patients 18 years or older who underwent nasal reconstruction after Mohs surgery in a tertiary care academic center between January 1, 2013, and August 31, 2015. Data on each patient included demographics, comorbidities, smoking status, details of the lesion, size of defect, subunits involved, and reconstructive technique. Patients were divided into 2 cohorts composed of those who had reconstruction with structural reinforcement (ie, cartilage grafting or suspension suture) and those with only soft-tissue reconstruction. Patients with nasal obstruction from the functional collapse of the reconstructed area and no history of nasal obstruction were included (n = 38). Patients who had a follow-up of less than 2 months, no alar or sidewall involvement, nasal obstruction secondary to turbinate hypertrophy, septal deflection or other nonstructural causes, and incomplete documentation for analysis were excluded (n = 102).

Main Outcomes and Measures

Rates of postoperative nasal obstruction secondary to nasal sidewall collapse and need for revision surgery.

Results

Of the 38 patients who met the inclusion criteria, 22 were men and 16 were women with a mean (range) age of 64.5 (35-92) years. Twenty-three patients (61%) underwent reconstruction by a facial plastic surgeon and 15 (39%) by 2 dermatologic surgeons. Three (8%) underwent reconstruction without reinforcement and experienced postoperative nasal obstruction. The mean size of reconstructed defects that resulted in nasal valve collapse was 2.1 cm in diameter (range, 1.2-2.6 cm). Defect size was associated with incidence of postoperative nasal obstruction. For defects greater than 1.2 cm in diameter, patients reconstructed without reinforcement had a statistically significant increase of nasal obstruction secondary to functional nasal collapse compared with patients reconstructed with reinforcement (3 of 14 [21%] vs 0 of 17; 95% CI, 0.005-0.358; P = .04).

Conclusions and Relevance

Nasal defects greater than 1.2 cm in diameter and involving the alar and sidewalls were associated with lower incidence of postoperative nasal obstruction when a structural reinforcement technique was used in reconstruction. The findings of this study support the structural reinforcement of the nasal functional subunits during Mohs reconstructive surgery to achieve optimal outcomes.

Auto-Rim Flap Technique for Lateral Crura Caudal Excess Treatment

BACKGROUND

There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities.

OBJECTIVES

In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties.

METHODS

The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions.

RESULTS

Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position.

CONCLUSIONS

With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary.

Simple Correction of Alar Retraction by Conchal Cartilage Extension Grafts

Background

Alar retraction is a challenging condition in rhinoplasty marked by exaggerated nostril exposure and awkwardness. Although various methods for correcting alar retraction have been introduced, none is without drawbacks. Herein, we report a simple procedure that is both effective and safe for correcting alar retraction using only conchal cartilage grafting.

Methods

Between August 2007 and August 2009, 18 patients underwent conchal cartilage extension grafting to correct alar retraction. Conchal cartilage extension grafts were fixed to the caudal margins of the lateral crura and covered with vestibular skin advancement flaps. Preoperative and postoperative photographs were reviewed and analyzed. Patient satisfaction was surveyed and categorized into 4 groups (very satisfied, satisfied, moderate, or unsatisfied).

Results

According to the survey, 8 patients were very satisfied, 9 were satisfied, and 1 considered the outcome moderate, resulting in satisfaction for most patients. The average distance from the alar rim to the long axis of the nostril was reduced by 1.4 mm (3.6 to 2.2 mm). There were no complications, except in 2 cases with palpable cartilage step-off that resolved without any aesthetic problems.

Conclusions

Conchal cartilage alar extension graft is a simple, effective method of correcting alar retraction that can be combined with aesthetic rhinoplasty conveniently, utilizing conchal cartilage, which is the most similar cartilage to alar cartilage, and requiring a lesser volume of cartilage harvest compared to previously devised methods. However, the current procedure lacks efficacy for severe alar retraction and a longer follow-up period may be required to substantiate the enduring efficacy of the current procedure.

Primary Open Rhinoplasty

Rhinoplasty is perhaps the most complex cosmetic surgery procedure performed today. It is characterized by an intricate interplay between form and function, with patient satisfaction being dependent not only on improvement of nasal appearance but also resolution of preexisting airway symptoms. The prerequisite for successful execution of this challenging procedure is a thorough understanding of nasal anatomy and physiology. Hence, a thorough preoperative evaluation is at least as important and the surgical skill in performing the operation. Establishing an accurate diagnosis through a comprehensive nasal analysis is obligatory. As to the surgical approach, much has been written about the advantages and disadvantages of closed vs open rhinoplasty. The more commonly chosen open approach has numerous advantages, including improved visualization without distortion, thus, enabling precise diagnosis and correction of deformities. While the surgical treatment of existing nasal deformities is tailored to the needs of the individual patient, the authors have noted a total of 10 essential components to form the foundation for successful technical execution of rhinoplasty. These include: (1) septoturbinotomy; (2) opening the nose; (3) humpectomy/spreader flaps; (4) tip-plasty; (5) supratip-plasty; (6) columellar strut; (7) dorsal augmentation; (8) nasal base reduction; (9) osteotomies; and (10) rim grafts. Postoperative, a variety of problems, such as edema, may be successfully addressed without surgical intervention. Diligent postoperative management is critical in ensuring a positive patient experience. Finally, a comprehensive understanding of possible postoperative complications, such as bleeding, ecchymosis, edema, and persistent or new iatrogenic deformity is mandatory prior to offering rhinoplasty to patients.

Rhinoplasty Complications and Reoperations: Systematic Review

Introduction This article is related to complications of rhinoplasty and its main causes of reoperations.

Objectives The objective of this study is to perform a systematic review of literature on complications in rhinoplasty.

Data Synthesis The authors conducted a survey of articles related to key terms in the literature by using three important databases within 11 years, between January 2002 and January 2013. We found 1,271 abstracts and selected 49 articles to this review.

Conclusion The main results showed that the number of primary open rhinoplasty was 7902 (89%) and 765 closed (11%) and the percentage of reoperations in primary open complete rhinoplasties was 2.73% and closed complete was 1.56%. The statistical analysis revealed a value of p = 0.071. The standardization of terms can improve the quality of scientific publications about rhinoplasty. There is no difference between primary open or closed rhinoplasty techniques in relation to reoperations.

Three-Dimensional Cartilage Graft Technique: A Different Management for Nasal Tip Surgery

PURPOSE

Nasal tip reconstruction is an important component in aesthetic rhinoplasty. Different congenital deformities or acquired disorders (trauma, infection, operations) may affect the nasal tip structure. Additionally, the natural appearance of the nasal tip projection can be lost after rhinoplasty. The lower lateral cartilages are the main structural component of the nasal alae and tip support. Any distortion or failure on the alar cartilages may lead to both functional and aesthetic problems. In this article, the author presents a different method for nasal tip support.

PATIENTS AND METHODS

Between 2010 and 2014, a chart review was performed of 64 consecutive primary rhinoplasty patients (29 women, 35 men). Postoperative follow-up period was at least 12 months. None of the patients were secondary patients or no nasal tip surgery was done previously. The patients with secondary rhinoplasty, saddle deformity, revision rhinoplasty, cleft lip nose, and crooked nose were excluded from the study.

RESULTS

The three-dimensional pyramid cartilage technique was used in all the patients with the open rhinoplasty approach to ensure the nasal tip projection. Average time was between 4 and 7 minutes for graft harvesting and suturing to the nasal tip in this technique. The follow-up period was between 12 and 48 months. There was a revision procedure in 4 patients because of the distortion of the tip graft and tearing of the graft material. The revision procedure was done for these patients.

DISCUSSION

In this article, the author presents "three-dimensional pyramid cartilage technique' as a new and alternative technique for better projection of the nasal tip. This technique also provided the support to nasal tip using only 1 graft material with minimal manipulation, with no donor area morbidity or another cartilage resection except the nasal septum.

The Crooked Nose

Correction of a crooked nose is one of the most common requests from patients presenting for rhinoplasty. Both esthetic and functional issues are typically present in patients with this deformity. Rhinoplasty for the crooked nose is particularly challenging because multiple nasal structures, both external and internal, are commonly involved. A major septal deformity is almost always a component of severely deviated noses. The crooked nose results from extrinsic and intrinsic forces that produce distortion of the nasal structures and nasal deviation. The open approach is particularly useful and is the focus of this article.

Reshaping of the Broad and Bulbous Nasal Tip

This article presents a contemporary overview of tip suturing and tip structural grafting techniques used to refine the wide nasal tip. Previous reductive techniques have proved to produce unnatural results over time. It is imperative to correctly evaluate the nose and assess all possible pitfalls during the preoperative period before outlining a surgical plan. Intraoperatively, an algorithmic approach helps obtain a reproducible and refined yet properly narrowed domal tip region with graceful contours that extend laterally to the alar lobule with proper shadowing.

Nasal Tip Deficiency

Nasal tip deficiency can be congenital or secondary to previous nasal surgeries. Underdeveloped medial crura usually present with underprojected tip and lack of tip definition. Weakness or malposition of lateral crura causes alar rim retraction and lateral nasal wall weakness. Structural grafting of alar cartilages strengthens the tip framework, reinforces the disrupted support mechanisms, and controls the position of the nasal tip. In secondary cases, anatomic reconstruction of the weakened or interrupted alar cartilages and reconstitution of a stable nasal tip tripod must be the goal for a predictable outcome.

Anatomical Study of the Lateral Crural Strut Graft in Rhinoplasty and Its Clinical Application

BACKGROUND

Lateral crural strut graft has been used in rhinoplasty to correct deformities such as bulbous nasal tip, lateral crus malposition, alar retraction, collapsed external valve, lateral crus concavity, and alar deformity after domal suture. Despite its widespread use, the lateral crural strut graft has not been the subject of studies that show its benefits objectively and statistically.

OBJECTIVES

To assess nasal anatomical variations in cadavers that underwent rhinoplasty using the lateral crural strut graft, considering the clinical applications of this graft.

METHODS

The study was conducted with 16 human cadavers that underwent rhinoplasty with lateral crural strut graft. The variables were basilar nasal width, interalar width, columella-nasal tip height, nostril's width, and length and width of the graft. Measurements were taken with a digital caliper before and after rhinoplasty, and nostril cross-sectional area was measured with a computer program. All measurements were submitted to statistical analysis.

RESULTS

Most of the cadavers were young, male, and black. Variables values were increased, but only basilar nasal width, columella-nasal tip height, and nostril cross-sectional area showed statistically significant differences (P < .05), leading to changes in the alar base, the nasal tip projection and the external nasal valve.

CONCLUSIONS

Lateral crural strut graft improves external nasal valve and increases nasal tip projection and basilar nasal width.

A Practical Approach to Rhinoplasty

Rhinoplasty continues to be one of the most commonly performed aesthetic surgical procedures. Over the past 25 years, the open approach has increased in popularity and is the focus of this article. The principles for successful rhinoplasty include comprehensive clinical analysis and defining rhinoplasty goals, preoperative consultation and planning, precise operative execution, postoperative management, and critical analysis of one's results. Systematic nasal analysis is critical to establish the goals of surgery. Techniques to address the nasal dorsum, nasal airway, tip complex, alar rims, and bony vault that provide consistent results are discussed.

Aesthetic and Functional Results of Lateral Crural Repositioning

IMPORTANCE

Thin or cephalically malpositioned lateral crura cause nasal obstruction by depressing nasal valves and decrease patient satisfaction with rhinoplasty as a result of nostril asymmetry and alar collapse.

OBJECTIVE

To demonstrate the aesthetic and functional efficacy of lateral crural repositioning with lateral strut grafting in patients with cephalic malposition of the lateral crura undergoing primary septorhinoplasty.

DESIGN, SETTING, AND PARTICIPANTS

We prospectively selected 80 patients with lateral crural malposition who underwent primary septorhinoplasty performed by the same surgeon from December 1, 2013, through May 30, 2014. The surgeon measured the angle between the lateral crura and midline intraoperatively with a goniometer to confirm malposition (angle, ≤30°). Data analysis was performed from March 13 to 23, 2015.

INTERVENTION

All the patients underwent primary rhinoplasty with the open approach. Lateral crural repositioning with lateral crural strut graft was used in all selected patients.

MAIN OUTCOME AND MEASURES

Preoperative and 6- and approximately 12-month postoperative scores on the Nasal Obstruction Symptom Evaluation (NOSE) scale (range, 0-20; decreased scores indicate improved functional results) and the Rhinoplasty Outcomes Evaluation (ROE) questionnaire (range, 0-24; increased scores indicate improved aesthetic results).

RESULTS

Seventy-five of 80 patients were confirmed to have cephalic malposition intraoperatively. Four patients were excluded owing to selection of different surgical techniques, leaving 71 patients for analysis. The mean (SD) and median postoperative NOSE scores at 6 months (3.18 [3.12] and 2.0) and 12 months (0.39 [1.07] and 0) showed significant improvement compared with the preoperative scores (6.96 [5.10] and 7.0) (P < .01 for each comparison). The mean (SD) and median postoperative ROE scores also showed significant improvement at 6 months (21.06 [3.82] and 23.0) and 12 months (23.12 [2.09] and 24.0) compared with preoperative scores (7.03 [3.70] and 6.0) (P = .001). However, the changes from preoperative to 12-month postoperative scores (mean [SD] and median) were not significantly different between patients with normal (NOSE scores, 8.41 [4.59] and 90 to 0.28 [0.79] and 0, respectively; ROE scores, 6.97 [3.24] and 6.0 to 23.31 [1.91] and 24.0, respectively) and thin (NOSE score, 6.59 [5.09] and 8.0 to 0.11 [0.33] and 0, respectively; ROE scores, 7.76 [3.82] and 7.0 to 23.29 [1.72] and 24.0, respectively) skin types and those with thick skin types (NOSE scores, 5.52 [5.42] and 4.0 to 0.72 [1.54] and 0, respectively; ROE scores, 6.60 [4.16] and 6.0 to 22.80 [2.53] and 24.0, respectively) (P > .05).

CONCLUSIONS AND RELEVANCE

Lateral crural repositioning is a useful and versatile technique to achieve successful functional and aesthetic results in a 1-year follow-up. We detected no significant difference by skin type in improvement of nasal function and aesthetic satisfaction.

Correction of Alar Retraction Based on Frontal Classification

Among the various types of alar deformations in Asians, alar retraction not only has the highest occurrence rate, but is also very complicated to treat because the ala is supported only by cartilage and its soft tissue envelope cannot be easily stretched. As patients' knowledge of aesthetic procedures is becoming more extensive due to increased information dissemination through various media, doctors must give more accurate, logical explanations of the procedures to be performed and their anticipated results, with an emphasis on relevant anatomical features, accurate diagnoses, detailed classifications, and various appropriate methods of surgery.

The alar rim flap: a novel technique to manage malpositioned lateral crura

BACKGROUND

Alar cartilage malposition is a common anatomic variation in which the axis of the lateral crus lies cephalically and may be parallel to the cephalic septum. Malposition of the lateral crura may produce inward collapse of the alae that is observable on deep inspiration.

OBJECTIVES

The authors performed the alar rim flap technique to treat patients with alar malposition and assessed functional and aesthetic outcomes.

METHODS

Twelve patients who underwent primary open rhinoplasty with the alar rim flap technique were evaluated in a prospective study. A 2- or 3-mm caudal portion of the lateral crus was elevated from the underlying mucosa, pulled caudally, and extended with a cartilage graft. This extension of the alar rim flap was placed through the pyriform aperture for additional support. Patients completed pre- and postoperative questionnaires addressing nasal obstruction and underwent paranasal computed tomography. Patients received follow-up for an average of 16 months (range, 8-27 months).

RESULTS

Patients with alar cartilage malposition and external valve insufficiency experienced aesthetic and functional improvements after rhinoplasty with the alar rim flap technique. No patients developed alar rim collapse or flap displacement.

CONCLUSIONS

The alar rim flap technique is effective for the correction of malpositioned lateral crura and external valve insufficiency. Because this technique does not damage the scroll area, disruption of the internal valve area is avoided.

[New aspects in surgery of the nasal tip]

The creation of both a functionally and aesthetically pleasing nasal tip contour is demanding and depends on a variety of parameters. Typically, procedures are performed with emphasis on narrowing the nasal tip structure. Excisional techniques alone inevitably lead to reduction in skeletal support and are often prone to unpredictable deformities. But long-term results of classical suture techniques have also shown unfavorable outcomes. Particularly pinching of the alae and displacement of the caudal margin of the lateral crus below the cephalic margin belong in this category. A characteristic loss of structural continuity between the domes and the alar lobule and an undesirable shadowing occur. These effects lead to an unnatural appearance of the nasal tip and frequently to impaired nasal breathing. Stability and configuration of the alar cartilages alone do not allow for an adequate evaluation of the nasal tip contour. Rather a three-dimensional approach is required in order to describe all nasal tip structures. Especially the rotational angle of the alar surface as well as the position of the lateral crus in relation to the cranial septum should be considered in the three-dimensional analysis. Taking the various parameters into account the authors present new aspects in nasal tip surgery which contribute to the creation of a functionally and aesthetically pleasing as well as durable nasal tip contour.

Lateral crural tensioning for refinement of the wide and underprojected nasal tip: rethinking the lateral crural steal

Refinement of the wide, ptotic, under protected tip is one of the most difficult challenges in cosmetic nasal surgery yet also among the most common. Although excisional techniques can produce reductions in lobular width, long-term contour alterations are unpredictable and subject to stigmatic tip deformity. Preservation of natural tip support is a fundamental requirement of a successful rhinoplasty. The traditional lateral crural steal is a useful technique for tip refinement, but, when combined with a sturdy septal extension graft, the modified lateral crural steal (lateral crural tensioning) becomes a more potent and versatile rhinoplasty technique that can improve tip contour without jeopardizing function or structural stability.

Lateral crural repositioning for treatment of cephalic malposition

After completion of this article, the reader should be able to describe the indications for lateral crural repositioning, understand the key steps to performing the procedure, and be able to manage the complications associated with this treatment strategy.

The correction of alar-columella web deformities in unilateral cleft-lip nasal deformities with web graft technique

BACKGROUND

Among the many secondary deformities in cleft-lip nose, the alar-columella web is unsightly and is a recurrent deformity. The purpose of this article is to revisit the correction of alar web deformity in patients with cleft-lip nasal deformities and to introduce our web graft technique.

METHODS

Thirteen patients with alar webbing underwent surgery between June 2012 and February 2013. The age range of the patients at the time of surgery was 14-29 years. An open rhinoplasty incision, including a reverse-U incision, was made and cartilage work was performed. After the cleft side was equalized with the dome angle of the healthy side, we used contralateral alar or auricular cartilage grafts as a stiff batten to stabilize the converted web skin. The web graft was fixed to the cleft-side web skin's inner side with at least three sutures to maintain the tucking of the vestibular skin. The follow-up period ranged from 1 to 20 months.

RESULTS

The postoperative frontal and basal views showed that the nostrils and columella had better shape. Most patients demonstrated correction of the drooping alar rim and satisfactory symmetry of the nostrils.

CONCLUSION

A web graft supports the vestibular lining of the reverse-U incision and increases the strength of the new concavity of the tucked skin. We expect that a long-lasting concave web contour could be achieved with this technique.

Lateral crus graft with autologous rib cartilage for cleft lip nostril asymmetry: a report of 35 cases

A surgical technique of lateral crus strut graft to correct the deformity of nostril contour and improve asymmetric nostril shape by autologous rib cartilage was reported. Thirty-five patients (20 males and 15 females), with a mean age of 19 years (range of 16-26 years) were included in this study. All of the patients suffered moderate to severe unilateral cleft lip nostril deformity and underwent surgical technique of lateral crus strut graft by autologous rib cartilage to correct the asymmetric nostril contour from 2010 to 2012. The views of the nostril contour on both sides were reviewed and some parameters were measured at different time points (preoperatively, and 3 months and one year postoperatively) including the long axis and short axis of the nostrils. The differences in nostrils including long axis, short axis, elliptical area and eccentricity on the both sides were compared at different time points. The differences in the long axis and eccentricity of the nostrils on the two sides were decreased significantly between the preoperative view and postoperative view (P<0.05). The surgical technique of lateral crus graft with autologous rib cartilage is effective to correct the abnormal nostril contour and improve the asymmetry for unilateral cleft clip patients.

Are grafts necessary in rhinoplasty? Cartilage flaps with cartilage-saving rhinoplasty concept

BACKGROUND

Cartilage grafts are used routinely in rhinoplasty, but are they necessary? Can we support the normal anatomy by preserving and transposing the adjacent tissues? In this study we hypothesize that during rhinoplasty, cartilage flaps can give adequate support and may decrease the need for cartilage grafts.

METHODS

Included in this study were 147 patients who underwent an open rhinoplasty technique under general anesthesia between January 2010 and May 2012. Mean operative time was 73 min (range=44-120 min). After dissection and septoplasty (if needed), we performed dorsal bone and septal reductions. Following reduction, upper lateral cartilage superior segments were preserved and turned inward as cartilage flaps to replace the spreader grafts. Lower lateral cartilage cranial parts were not excised and were slid over the caudal part to replace the alar strut grafts. Cartilage from the caudal nasal septum was not excised; instead, lower lateral cartilages were cephaloposteriorly displaced with a tongue-in-groove technique to support the nasal tip.

RESULTS

Mean follow-up time was 19.6 months (6-30 months). All patients but 12 were satisfied or completely satisfied with the results. Among the 12 unsatisfied patients, four complained of a one-sided inverted-V deformity (secondary spreader grafts were added), three had supratip deformity (secondary additional dorsal septal excisions), two demanded extra tip definition (secondary tipoplasty), two were unhappy with the bone symmetry (secondary osteotomies), and one complained of hanging columella (secondary excision from the caudal septum).

CONCLUSIONS

Cartilage flaps have some advantages over cartilage grafts. First, graft harvest is not needed in the former; second, because flaps are a part of the normal anatomy, they provide a good tissue match, making fixation easier. However, the tongue-in-groove technique cannot be used in patients who do not need caudal excision, and cartilage flaps can be inadequate in some patients who may need additional grafts.

Alar retraction: etiology, treatment, and prevention

IMPORTANCE

The effect of different rhinoplasty maneuvers on alar retraction remains to be elucidated.

OBJECTIVE

To determine the etiology and treatment of alar retraction based on a series of specific rhinoplasty maneuvers.

DESIGN

Retrospective review of a single surgeon's rhinoplasty digital photo database, examining preoperative alar retraction from January 1, 2002, to December 31, 2005, in 520 patients. Patients with more than 1 mm of alar retraction on preoperative photographs were identified. Postoperative photographs were examined to determine the effect of specific rhinoplasty maneuvers on the position of the alar margin; these maneuvers included cephalic trim, cephalic positioning of the lower lateral cartilage, composite grafts, alar rim grafts, alar batten grafts, and overlay of the lower lateral cartilage.

SETTING

Tertiary care academic health center.

PARTICIPANTS

Forty-five patients with alar retraction met inclusion criteria, resulting in 63 nasal halves with alar retraction.

MAIN OUTCOMES AND MEASURES

Intraoperative findings, postoperative results.

RESULTS

Forty-seven percent of the patients (n = 21) had prior surgery; 47% also had cephalically positioned lower lateral cartilages. Among patients with less than 4 mm of cartilage width at the outset, 46% of those who received supportive grafts achieved target correction vs only 7% for patients who did not undergo supportive cartilage grafting. In patients who underwent more than 4 mm of cephalic trim, those who received supportive grafts achieved 46% of target correction vs 11% among those who did not. Ninety-five percent of composite grafts, 69% of alar strut grafts, 47% of alar rim grafts, 43% of vertical lobule division, and 12% of alar batten grafts achieved their target correction values.

CONCLUSIONS AND RELEVANCE

Alar retraction is a highly complex problem. It can be seen de novo and is associated with cephalically positioned lower lateral cartilages. Structurally supportive grafting-including composite grafts, alar strut grafts, alar rim grafts, vertical lobule division, and alar batten grafts-can improve alar retraction.

Evaluating the effectiveness of the lateral intercrural suture to decrease the interdomal distance to improve the definition of the nasal tip in primary rhinoplasty

Introduction Several surgical techniques emphasizing sutures on the lower lateral cartilage have been studied by surgeons as instruments to improve nasal tip remodeling. It is already known that the domal divergence angle and its definition angle can be modified by lateral intercrural suture (LIS). Techniques for measuring these structures are not yet standardized.

Objectives Assess the efficacy of LIS using polydioxanone 4–0 absorbable thread by interdomal distance and systematize the LIS technique to improve nasal tip definition.

Materials and Methods This prospective study measured and analyzed interdomal distances measured preoperatively and perioperatively compared with 3- and 6-month postoperative measurements.

Results LIS was efficient on reducing interdomal distances.

Conclusion LIS is statistically safe and efficient and has low morbidity when utilized in patients with mild to moderate deformities, because it reduces the domal divergence angle, effectively sustaining the nasal tip.

Comparison of the effects of columellar strut and septal extension grafts for tip support in rhinoplasty

BACKGROUND

The purpose of this study was to compare the effects of columellar strut and septal extension grafts for reconstruction of caudal nasal supportive structures on the long-term stability of nasal projection and rotation.

METHODS

A comparison was done on the differences between the early- and long-term results of the ratios of nasal projection to nasal length and columella labial angle values in 36 patients who were operated on by the same surgeon using columellar or septal extension grafts.

RESULTS

Both grafts had the effect of increasing nasal projection, and this effect was found to be stable over time. Some increased values of nasal projection obtained in the early postoperative period were lost over time. Although no significant difference was found between the groups, clinical and numerical observations showed that the values decreased less in the group that received septal extension grafts.

CONCLUSION

The tip position was more stable in cases with septal extension grafts than in those with columellar strut grafts.

Modified technique to increase nostril cross-sectional area after using rib and septal cartilage graft over alar nasal cartilages

PURPOSE

Describe a modified technique to increase nostril cross-sectional area using rib and septal cartilage graft over alar nasal cartilages.

METHODS

A modified surgical technique was used to obtain, carve and insert cartilage grafts over alar nasal cartilages. This study used standardized pictures and measured 90 cadaveric nostril cross-sectional area using Autocad(®); 30 were taken before any procedure and 60 were taken after grafts over lateral crura (30 using costal cartilage and 30 using septal cartilage). Statistical analysis were assessed using a model for repeated measures and ANOVA (Analysis of Variance) for the variable "area".

RESULTS

There's statistical evidence that rib cartilage graft is more effective than septal cartilage graft. The mean area after the insertion of septal cartilage graft is smaller than the mean area under rib graft treatment (no confidence interval for mean difference contains the zero value and all P-values are below the significance level of 5%).

CONCLUSIONS

The technique presented is applicable to increase nostril cross section area in cadavers. This modified technique revealed to enhance more nostril cross section area with costal cartilage graft over lateral crura rather than by septal graft.
