The value of spreader grafts in rhinoplasty: a critical review

Functional evaluation of Septal L-strut extension graft in East Asians

BACKGROUND

The septal L-strut extension graft (SLEG) consists of anterior extended spreader graft and caudal septal extension graft. SLEG is used to increase the anterocaudal projection from a low-profile nose by creating the de-novo septum. This retrospective study verified the effectiveness of SLEG in improving the nasal function in East Asians.

MATERIALS

Medical records of patients who underwent septorhinoplasty with SLEG were retrospectively reviewed. The clinical features showed under-projected lower two-thirds of the nose with septal deviation, saddle nose, and short nose. We analyzed the post-operative changes in the NOSE score and variables of nasal geometry measured using acoustic rhinometry through long-term follow-up.

RESULTS

Patients were divided into two groups, those who underwent SLEG with turbinoplasty (Group A) and SLEG alone (group B). The NOSE scores decreased significantly in groups A and B, and the improvement was statistically more significant in Group A (p < 0.05). Acoustic rhinometry showed an increase in nasal cavity volume (VOL1) on the deviated side in Group A, and an increase in minimal cross-sectional area 1 (MCA1) on the deviated side in Group B (p < 0.05). The non-deviated side did not show significant reduction in MCA1 and VOL1 after SLEG with or without turbinoplasty. Thus, SLEG, by itself, improved airway function in East Asians.

CONCLUSIONS

SLEG has proven to be valuable in improving nasal function.

Facial Gender-Affirming Surgery: Pitfalls, Complications, and How to Avoid Them

Facial feminization is a complex undertaking requiring skill in both craniofacial and aesthetic plastic surgery. As in aesthetic procedures, understanding the patient's goals and setting realistic expectations in light of an individual's anatomy is critical. Both soft tissue and bone must be addressed to adequately soften masculine facial features. This article delves into specific anatomic areas and delineates some of the pathways to successful outcomes.

Management of the Middle Vault

Early reductive rhinoplasty techniques focused on hump reduction and tip plasty with minimal focus on treating or preserving the integrity and width of the middle vault. With time, rhinoplasty surgeons noted the aesthetic and functional complications of the deformities that may occur in the middle vault with reduction techniques and developed methods to treat and also avoid these complications. Thus, the importance of protecting the integrity of the middle third of the nose has been increasingly emphasized over the years. Primary deformities of the middle vault that result in nasal obstruction require attention of the rhinoplasty surgeon, as well as preservation of support structures of the middle vault and internal nasal valve to minimize secondary deformities and functional compromise after rhinoplasty surgery.

Septal Reconstruction: Simple to Complex

Nasal septal deviation is a frequent problem treated by otolaryngologists and facial plastic surgeons. Complete correction of the septal deformity is often essential both for straightening a crooked nose and for restoration of the nasal airway. While standard septoplasty techniques provide excellent outcomes in most patients, severe septal deformities may require treatment with more advanced maneuvers including adjacent grafting, caudal septal replacement, and even extracorporeal septoplasty. This article reviews a range of septoplasty techniques, with an emphasis on complex septal reconstruction and approaches that can be utilized to maintain keystone stability and establish a robust midline L-strut even in cases with challenging anatomy.

Evolution and Versatility of the Bilateral Extended Spreader Graft: A Review and an Update to the Tongue-and-Groove Technique

BACKGROUND

Initially introduced by the senior author (B.G.) for lengthening the short nose, bilateral extended spreader grafts (BESG) in the form of the tongue-and-groove (TAG) technique have gained additional indications in current septorhinoplasty practice. The purpose of this study is to discuss the evolution of this versatile technique with a literature review and retrospective review of the senior author's experience.

METHODS

PubMed searches were conducted for "bilateral extended spreader graft" and "tongue-and-groove rhinoplasty". A retrospective chart review was performed for septorhinoplasty patients at the senior author's practice between 2015 and 2020.

RESULTS

BESG have been used to realign the deviated nose and control nasal length. In addition to lengthening the short nose, the BESG technique can augment tip projection and align the caudal nose structures. A total of 397 septorhinoplasty patients were reviewed for this study. There were 258 (65.0%) cases of primary septorhinoplasties. The BESG technique was used in 31 (7.8%) patients for the nose elongation, all of whom underwent an open surgical approach. Bilateral spreader grafts (extended and non-extended) were used in 162 (40.8%) patients; among these patients, 135 (34.0%) had columellar struts placed concomitantly.

CONCLUSION

In addition to nasal elongation, BESG can increase tip projection and better align the tip with the dorsum. The BESG technique continues to be highly consistent and dependable for correcting difficult nasal deformities.

Comparing the Efficacy of Large Language Models ChatGPT, BARD, and Bing AI in Providing Information on Rhinoplasty: An Observational Study

Background

Large language models (LLMs) are emerging artificial intelligence (AI) technologies refining research and healthcare. However, the impact of these models on presurgical planning and education remains under-explored.

Objectives

This study aims to assess 3 prominent LLMs-Google's AI BARD (Mountain View, CA), Bing AI (Microsoft, Redmond, WA), and ChatGPT-3.5 (Open AI, San Francisco, CA) in providing safe medical information for rhinoplasty.

Methods

Six questions regarding rhinoplasty were prompted to ChatGPT, BARD, and Bing AI. A Likert scale was used to evaluate these responses by a panel of Specialist Plastic and Reconstructive Surgeons with extensive experience in rhinoplasty. To measure reliability, the Flesch Reading Ease Score, the Flesch-Kincaid Grade Level, and the Coleman-Liau Index were used. The modified DISCERN score was chosen as the criterion for assessing suitability and reliability. A t test was performed to calculate the difference between the LLMs, and a double-sided P-value <.05 was considered statistically significant.

Results

In terms of reliability, BARD and ChatGPT demonstrated a significantly (P < .05) greater Flesch Reading Ease Score of 47.47 (±15.32) and 37.68 (±12.96), Flesch-Kincaid Grade Level of 9.7 (±3.12) and 10.15 (±1.84), and a Coleman-Liau Index of 10.83 (±2.14) and 12.17 (±1.17) than Bing AI. In terms of suitability, BARD (46.3 ± 2.8) demonstrated a significantly greater DISCERN score than ChatGPT and Bing AI. In terms of Likert score, ChatGPT and BARD demonstrated similar scores and were greater than Bing AI.

Conclusions

BARD delivered the most succinct and comprehensible information, followed by ChatGPT and Bing AI. Although these models demonstrate potential, challenges regarding their depth and specificity remain. Therefore, future research should aim to augment LLM performance through the integration of specialized databases and expert knowledge, while also refining their algorithms.

Is There a Risk of Saddle Nose Deformity after Spreader Grafts and Flaps?

Spreader grafts have been used successfully for years to augment the nasal valves among other indications. Spreader flaps have been described as an alternative. However, the literature discussing the complications of these procedures is scarce. This study aims to report and discuss the improvements and complications resulting from using spreader grafts or flaps in a cohort of patients operated upon by the author. Particular stress is given to a group of patients who developed saddle nose deformity after surgery. This cohort included 80 cases of rhinoplasty involving the use of spreader grafts or/and flaps. There was a highly significant improvement in nasal functions postoperatively. Postoperative saddle nose deformity was observed in five patients (6.25%). Spreader grafts/flaps are highly effective in improving nasal functions, but saddle nose deformity appears to be a possible risk. This complication has not been previously reported in the literature in relation to these procedures.

Understanding Nasal Valve Compromise in Nasal Airway Obstruction: A New Classification System

OBJECTIVES

A key aspect of rhinoplasty is integrity of nasal valves area because of its fundamental role in patent nasal airway. furthermore, nasal obstruction is a dominant feature in patient with nasal valves dysfunction (NVD) which can be devastating outcome after rhinoplasty.

METHODS

Nonetheless, NVD has been widely investigated regarding their etiologies and management. However, it has been assumed that the anatomical complexity and interplay between its structures causing a confusion for a beginner surgeon to diagnose and treat NVD. This study was approved by the institutional review board of Chosun University Hospital, Gwangju, Korea (2022-11-005).

RESULTS

To date, the lack of consensus on nasal valve pathologies and corrective procedures has led to its underestimations during analysis and management. As result, we proposed a classification system based on its affected anatomical part, location, and their management. Thus, implementing a classification system for NVD will help guide the practice of rhinoplasty and introduce a more structured approach.

CONCLUSION

This approach will prove useful in expanding our understanding of how important to locate the pathology of NVD and apply the most relevant management options, particularly for a beginner surgeons.

Novel method for correcting cephalic rotation in Asian nasal tip plasty

BACKGROUND

To correct nasal tip cephalic rotation, SEG made of cartilage or Medpor are often used in rhinoplasty. These techniques require extensive experience for the surgeon, and not all patients can accept this procedure. In this research, we introduce a new method to correct nasal tip cephalic rotation that is relatively simple and rapid.

METHODS

Fifty-nine patients who had rhinoplasty using our scaffold were enrolled in the study between January 2020 and January 2021. The authors evaluated the change of nasolabial angel by photogrammetry using standardized clinical photogrammetric techniques. Patients' satisfaction regarding postoperative results was also surveyed.

RESULTS

The mean postoperative follow-up duration was 12 months. No complication (infection, extrusion, and displacement) was happened in all patients. Analysis showed our scaffold can correct nasal tip cephalic rotation effectively (98.61±1.21 preoperatively and 89.68±0.99 postoperatively, P<0.0001). And the patient satisfaction rate is 98%.

CONCLUSION

We constructed an integrated scaffold by simply folding and suturing a high-density polyethylene sheet (Su-Por) sheet to correct nasal tip cephalic rotation. Using the scaffold we designed, we did not need to alter the structure of the nasal septum, which reduced the operative duration and simplified the surgical procedure.

Aesthetic and Functional Consequences of Spreader Graft without Suturing To the Upper Lateral Nasal Cartilage: A Randomized Double-Blinded Clinical Trial

Background

Considering the importance of the spreader graft technique in order to prevent collapse and airway retention and the importance of its effect on the dorsal aesthetic line and nasal width, in this study we compared the outcome of suturing spreader graft to septum _upper lateral cartilageas the classic technique to suturing spreader graft only to septum.

Methods

This comparative observational study was conducted on 50 consecutive patients referred to Rhinoplasty Department in 15 khordad Hospital from 2019 - 2020 . The study participants were randomly assigned into two groups which scheduling the new spreader graft technique without suturing the upper lateral cartilage (n = 25) or the frequent spreader graft technique with suturing to both septum and upper lateral nasal cartilage (n = 25). The nasal obstruction degree, the status and health-related quality of life, patients' satisfaction, and subjective mental image of the nasal structure were the study endpoint. The patients were followed-up for six months.

Results

The two groups were matched for gender and age. Although all study endpoints significantly improved in both groups, but the six-month trend of the change in each parameter was different in the two groups with superior improvement in those who planned for spreader graft technique without suturing the upper lateral cartilage.

Conclusion

In patients scheduling for selective rhinoplasty, new procedural technique including spreader graft without suturing to upper lateral cartilage can lead to more postoperative favorable outcome with regard to patients' satisfaction of the procedure, lack of obstructive symptoms, aesthetic feature, and health-related quality of life as compared to suturing to both septum and upper lateral cartilage.

Comparative Functional Effect of Alternative Surgical Techniques Used in Rhinoplasty

OBJECTIVE

The purpose of this investigation is to compare the functional effect of the different surgical techniques used for addressing each section of the nose.

METHODS

Prospective study of 57 consecutive rhinoplasty patients. Patients were evaluated with peak nasal inspiratory flow (PNIF), Nasal Obstruction Symptom Evaluation (NOSE), and Visual Analog Scale (VAS) for nasal obstruction before and 1 year after rhinoplasty. Additionally, esthetic evaluation of the nose was obtained with Rhinoplasty Outcomes Evaluation (ROE). According to the surgical technique used to address each portion of the nose, groups of patients were created and the functional improvement of these groups was compared.

RESULTS

Using the TukeyHSD multiple pairwise-comparison test, the estimated difference of the increase of PNIF between using spreader grafts and using spreader flaps was 94.9 (95% CI 24.3, 165.5, P = .004) between spreader grafts and neither grafts or flaps was 79.2 (95% CI 5.8, 152.6, P = .03), between spreader grafts and bilateral spreader flaps plus a unilateral spreader graft was 90.2 (95% CI 22.1, 158.2, P = .005). In all other portions of the nose, no significant difference was found in the functional improvement between different surgical techniques.

CONCLUSIONS

Spreader grafts increase PNIF more significantly than other surgical techniques used for dorsal mid-vault reconstruction. Spreader grafts should be preferred over other techniques whenever an improvement of nasal airflow is required. No significant differences were found between the functional effect of alternative techniques used in other sections of the nose. Additional cohort studies will be necessary to further confirm data from this investigation.

Complications Associated with Spreader Grafts and Spreader Flaps: A Systematic Review

BACKGROUND AND PURPOSE

Spreader grafts and spreader flaps are one of the most common techniques utilized in rhinoplasty surgeries. The aim of this study was to determine the complications, satisfaction, and revision rates associated with spreader grafts and spreader flaps and to compare these two modalities.

MATERIALS AND METHODS

PRISMA guidelines were followed for conducting this systematic review. The authors searched the literature systematically for pertinent materials in PubMed/Medline and Google Scholar. Inclusion criteria of this search included: randomized and non-randomized clinical trials, cohorts, and case series with more than 5 participants on rhinoplasty using spreader grafts or spreader flaps with detailed report either on complications, revision, and satisfaction rates. Furthermore, exclusion criteria included: any cadaveric or non-human study, case reports, technical notes, and review articles.

RESULTS

The initial literature search yielded a total of 193 studies. Following screening each paper and implementing the inclusion and exclusion criteria, 40 articles were chosen. In the spreader graft group, from 21 studies reporting complications, 6 of them reported no complication. The most common complications were nasal obstruction, inverted V deformity and open roof deformity, deviation, and infection. In the spreader flap group, from 6 studies reporting any existing complications, 1 reported no complications. Five other studies reported some degree of complications. In terms of revision rate, 10 patients (0.62%) underwent revision surgery after spreader graft placement, while only 2 patients (0.35%) revised surgically in the spreader flap group.

CONCLUSION

These two methods seem to have no significant difference in terms of complication rates, and both are recommended as a choice in middle vault reconstruction when each of their clinical use is indicated.

Balanced Cantilever Graft for Supporting the Cartilaginous Side Wall of Nose

BACKGROUND

Many locations for the nasal valve have been suggested, and more recently the concept of the flow-limiting segment was introduced. Rather than being controlled by an internal and external valve, flow through the nose is regulated by the cartilaginous side wall, septum, and inferior turbinate.

OBJECTIVES

The aim of this study was to assess the balanced cantilever graft (BCLG) as a technique to support the lateral nasal wall.

METHODS

Patients undergoing primary open septorhinoplasty over a 2-year period were studied. Follow-up period was a minimum of 6 months to a maximum of 24 months. Subjective improvement of function was measured with a visual analog scale (VAS) and aesthetic outcomes by FACE-Q score. Objective assessment of the airway was performed with a nasal peak inspiratory flow (NPIF) meter. Strips of septal cartilage of sufficient dimensions were placed in submucosal pockets created under the area of the lateral wall to be supported.

RESULTS

Sixty patients received BCLGs. The VAS score for nasal obstruction increased from 2.6 preoperatively to 8.1 postoperatively. FACE-Q increased from 16.7 preoperatively to 36.6 postoperatively. NPIF was 74.9 L/minute preoperatively, improving to 95 L/minute postoperatively. Statistically significant improvements were seen in these functional and aesthetic scores.

CONCLUSIONS

BCLGs support the weakened part of lateral nasal wall by their elastance. Minimal cartilage is required and the graft can be altered to support various parts of the lateral nasal wall. This graft does not cause an aesthetic deficiency whilst providing adequate support.

Accurate and Specific Measuring Grid for Otorhinolaryngological Surgeries

Most of the ENT surgeries (tympanoplasty, rhinoplasty, ossiculoplasty, septoplasty) involve the reconstruction and the functional correction of the respective structures involved. Success of otorhinolaryngological surgeries depends on accurate measurements and precision in judgement. There is need to develop simple tools for measurements which are easy to procure, accurate and simple to handle. Every surgeon needs unique tools to accomplish such an outcome. In order to tackle this difficulty and to ease the learning process in ENT surgeries, we have developed an accurate specific measurement grid.

Modified alar batten grafts for treatment in nasal valve dysfunction: Our experience

OBJECTIVE

Alar batten grafts are used to treat in nasal valve dysfunction (NVD). They can be placed by open or closed rhinoplasty using rib, septal, or auricular concha cartilage. Our surgical team used a modified placement of the classic alar batten.We aim to describe these changes and to the technique and demonstrate that modified alar batten grafts can improve the effects of spreader grafts and classic alar batten grafts.

METHODS

A retrospective study of 91 functional rhinoplasties was performed from March 2011 to November 2019 at a public university hospital in Murcia. The patients were divided into three groups. Group A included patients operated on using spreader grafts, group B included patients operated on using spreader grafts associated with alar batten grafts fixed to the caudal edge of the lateral crura of the lower lateral cartilage (LLC), and group C included patients operated on using modified alar batten grafts.

RESULTS

A total of 91 functional rhinoplasties were performed, 31 patients were operated on in group A, 27 patients were operated on in group B, and 33 patients were operated on in group C. The success rate was 67.7% in group A, 70.4% in group B and 93.9% in group C.

CONCLUSION

Modified alar batten grafts achieved better results than spreader grafts and spreader grafts associated with classic alar batten grafts. The size, position and placement of the sutures of modified alar batten grafts were the key factors in improving our results.

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.

Spreader Graft Placement: An Effective Procedure for Alleviation of Internal Nasal Valve Collapse

PURPOSE

The internal nasal valve (INV) is one of the most commonly involved areas in patients with nasal obstruction, and surgeries such as turbinate reduction and septal recontouring affect the physiology of the nasal valve area. With this concept, a cohort study was conducted to evaluate spreader graft's effectiveness in recontouring INV and relieving nasal obstruction.

MATERIALS AND METHODS

A prospective cohort study was performed, including patients with nasal obstruction with INV involvement. To quantify and compare the amount of nasal obstruction, Gertner Metal Plate (GMP) was used, and to assess the relief in associated symptoms, the Sino-Nasal Outcome Test (SNOT-22) was taken into consideration. GMP and SNOT 22 were performed preoperatively and postoperatively at the 1^st, 3^rd, and 6^th months, and the data obtained were analyzed by SPSS 22 software using paired t-tests. The postoperative broadening of the nasal dorsum and patient satisfaction with the surgical outcome were also assessed using the visual analog scale .

RESULTS

A total of 38 patients were included, with 28 males and 10 females. The data obtained were analyzed by using paired t-tests. Improvement in GMP assessment showed that t = 10.392305, 13.391485, and 15.985243 at the 1^st, 3^rd, and 6^th months, respectively, with an overall P ≤ .00001 and relief in associated symptoms assessed by SNOT 22 computed t = 12.24228, 15.824486, and 18.046395 at the 1^st, 3^rd, and 6^th month, respectively, with an overall P ≤ .00001. A total of 81.57% of patients did not perceive significant nasal dorsum broadening, and 86.84% of patients were highly satisfied by the surgical outcome based on the visual analog scale.

CONCLUSION

We conclude that in patients with nasal obstruction associated with INV involvement, spreader grafting provides rapid relief of nasal obstruction and associated symptoms, does not cause any appreciable broadening, and provides a high degree of patient satisfaction. Hence, it should be preferred over septal recontouring and turbinate reduction.

Spare Roof Technique Versus Component Dorsal Hump Reduction: A Randomized Prospective Study in 250 Primary Rhinoplasties, Aesthetic and Functional Outcomes

BACKGROUND

Most Caucasian aesthetic rhinoplasty patients complain about having a noticeable hump in profile view. Taking the integrity of the middle vault into consideration, there are 2 ways to dehump a nose: the structured technique and the preservation technique.

OBJECTIVES

The aim of this study was to compare the aesthetic and functional outcomes of 2 reduction rhinoplasty techniques.

METHODS

We performed a prospective, randomized, interventional, and longitudinal study on 250 patients randomly divided into 2 groups: the component dorsal hump reduction group (CDRg) (n = 125) and the spare roof technique group (SRTg) (n = 125). We utilized the Utrecht Questionnaire for Outcome Assessment in Aesthetic Rhinoplasty. Patients answered the questionnaire before the surgery, and at 3 and 12 months after surgery. In addition, we utilized a visual analog scale (VAS) to score nasal patency for each side.

RESULTS

Analyses of the preoperative and postoperative aesthetic VAS scores showed a significant improvement in both groups, from 3.66 to 7.00 (at 3 months) to 7.35 (at 12 months) in the CDRg, and from 3.81 to 8.14 (at 3 months) to 8.45 (at 12 months) in the SRTg. Analyses of postoperative means of aesthetic VAS scores showed a significant improvement in both groups over time. However, aesthetic improvement was higher in the SRTg than in the CDRg at both 3 (P < 0.001) and 12 months (P < 0.001) postsurgery. Analyses of the mean functional VAS scores showed a significant improvement with both techniques, with a better result for the SRTg.

CONCLUSIONS

The SRT is a reliable technique that can help deliver consistently better aesthetic and functional results than CDR for reduction rhinoplasty in Caucasian patients with a dorsal hump.

Functional and aesthetic outcomes of spreader graft and auto-spreader flap after nasal hump removal

Background

Following the reduction of the nasal hump to a desired level, spreader grafts are usually positioned to prevent the complication of nasal valve collapse. Auto-spreader flap is a new technique that gained more popularity recently and can be used as an alternative to spreader graft. This RCCT compared between both techniques aesthetically and functionally as well as the operative time.

Results

Forty patients, 17 males (42.5%) and 23 females (57.5%), were included. The mean duration of operation in auto-spreader flap was 11.8 ± 3.4 min, while it was 19.2 ± 3.2 min in spreader graft. The difference between the two procedures was statistically significant (P < 0.05). Functional assessment of nasal obstruction was done for all patients in both groups preoperative that was (75.6 ± 19.9) which showed marked improvement when re-evaluated 3 moths postoperatively (18.9 ± 14.7), and after 6 months NOSE scale was (29.1 ± 20.2). The overall aesthetic satisfaction was 62.5% (25 of 40) irrespective of the surgery done. Sixteen out of 20 patients in spreader group and 9 out of 20 in auto-spreader flap group.

Conclusion

Auto-spreader flap and spreader graft are very effective surgical procedure for treatment of nasal obstruction due to internal nasal valve dysfunction, but the auto-spreader flap had shorter operative time. However, spreader graft has a superior aesthetic outcome.

Challenging Rhinoplasty for the Cleft Lip and Palate Patient

Cleft lip and palate patients represent one of the most challenging groups of patients for septorhinoplasty, presenting as a complex surgical obstacle for even the most seasoned surgeons. These individuals have undergone several surgeries throughout their lives, resulting in a considerable amount of scar tissue, significant asymmetries and structural deficits. Key factors in successfully treating cleft lip and palate patients are the reconstruction of the absent/asymmetric cartilages and the replacement of bony structures. The use of autogenous rib cartilage allows the surgeon to create various grafts as well as fortify the soft tissue to resist persistent soft tissue deformities.

A Comparison of the Aesthetics Outcomes and Respiratory Side Effects of the Use of Spreader Flap and Spreader Graft Techniques in Open Rhinoplasty

BACKGROUND

Considering the fact that both spreader flap and spreader graft techniques cause respiratory complications and yield different aesthetics results in patients undergoing open rhinoplasty, this study was aimed at comparing these 2 techniques in terms of aesthetics and respiratory side effects.

METHODS

The study was conducted on patients undergoing open rhinoplasty in Ardabil, Iran, during 2016 to 2017. During the Study, a questionnaire containing 7 items related to respiratory complications and 7 items related to aesthetics side effects was completed for each of the patients. After that, the patients were photographed from 6 standard views by the researchers and then the aesthetics side effects were assessed. Finally, the obtained data were all fed into SPSS Software Version 16 and the needed statistical analyses were conducted.

RESULTS

One hundred thirty patients were investigated in this study the majority of whom were female. Rhinoplasty in 69 of them was done with spreader graft technique and in 61 of them with spreader flap technique. The analysis of the side effects in these 2 groups of patients indicated that the use of spreader graft technique increases the incidence of nasal hump while the use of spreader flap technique results in an increase in the incidence of obstructive sleep apnea. As regards the other respiratory and aesthetics side effects, the 2 techniques did not yield significantly different results.

CONCLUSION

The findings of the present research indicated that there is no significant difference between the use of spreader graft and spreader flap techniques. Therefore, considering the clinical conditions of patients, either of the 2 techniques can be used effectively in rhinoplasties.

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.

Outcome of rhinoplasty in patients undergoing autospreader flaps without notable dorsal hump reduction: A clinical trial

BACKGROUND

Reconstruction of the nasal midvault is an important component of successful rhinoplasty outcomes. Use of the autospreader flap is a beneficial technique for preserving the middle vault. In the present study, we evaluated the esthetic and functional outcomes of this technique in patients without notable dorsal hump reduction.

METHODOLOGY

A nonrandomized clinical trial was performed from December 2017 to April 2018 with a minimum follow-up time of 6 months. From among patients seeking rhinoplasty, 38 were eligible for inclusion in the study. The autospreader flap was used to recreate the middle vault in patients undergoing open rhinoplasty, with up to 2 mm bony and cartilaginous dorsal hump removal. Preoperative and postoperative standard photographs were obtained. Assessment of patients was based on Rhinoplasty Outcome Evaluation (ROE) and Nasal Obstruction Symptom Evaluation Scale (NOSE) scores. Objective assessment included quantitative analysis of anthropometric angles, mean dorsal width, nasal length, and projection which was performed on standard pre- and postoperative photos.

RESULTS

Overall, the patients had statistically significant improvement in their postoperative NOSE scores (9 vs. 6.92, p = 0.0001). The majority of patients were satisfied with the postoperative appearance of their noses. The mean nasal dorsal width (NDW) decreased postoperatively (43% vs. 36%). No difference was found between the mean height of the nose and projection pre- and postoperatively. There was a significant postoperative increase in the nasolabial angle and reduction in nasal length.

CONCLUSIONS

The autospreader flap is an effective technique for preservation and restoration of the middle vault and dorsal esthetic line in cases of less than 2 mm dorsal hump reduction. Nasal function can be improved while achieving good cosmetic outcomes.

The Effect of Spreader Graft and Mattress Suture Technique on Rhinoplasty in Patients With Nasal Hump Smaller Than 3 mm

INTRODUCTION

Rhinoplasty is a common plastic surgery that potentially has some complications such as postoperative deformities and breathing problems. A humpy nose is among the main reasons for rhinoplasty. Nasal valve (the narrowest part of the nasal airway) collapse may be occurred after nasal hump removal. Spreader graft is essential after more than 3 mm nasal hump removal. But the value of this graft is unknown for patients with nasal hump smaller than 3 mm. Mattress suture is another technique for widening the nasal valve angle. This study compares the effects of spreader graft and mattress suture technique on postoperative deformity and nasal valve patency in patients with nasal hump smaller than 3 mm as compared with control group (no graft and suture).

METHODS

In this clinical trial study 210 patients who underwent rhinoplasty with 2 different techniques involved. Their postoperative deformity and nasal valve patency were evaluated by subjective (questionnaire and digital photography) method before and after rhinoplasty during 6 months follow-up.

RESULTS

Statistically, nasal obstruction had no significant difference before and after rhinoplasty and no significant difference was observed between spreader graft and mattress sutures (P > 0.05), but significantly better results than control group (P < 0.05).

CONCLUSION

In this study the results of nasal valve patency of 2 techniques were similar. Because of several considerations in spreader graft technique such as needing to septoplasty in this technique even in patients without septal deviation that causes longer surgical duration, excessive blood loss, it is recommended to use Mattress suture in patients with nasal hump smaller than 3 mm.

Effect of Spreader Graft on Nasal Functions in Septorhinoplasty Surgery

OBJECTIVE

The authors aimed to investigate the effect of spreader grafts on nasal function in septorhinoplasty (SRP).

METHODS

A prospective randomized double-blind study was conducted. Thirty patients who underwent SRP operation between October 2011 and January 2013 were divided into 2 equal groups randomly. Fifteen patients underwent SRP surgery without spreader graft technique (Group I) and 15 patients underwent SRP surgery with spreader grafts (Group II). Preoperative and postoperative evaluation included visual analog score (VAS) and acoustic rhinometry test.

RESULTS

Visual analog scores and acoustic rhinometry measurements of Group I and Group II patients were compared. Statistically significant difference was found for VAS scores of both the sides of the nasal cavity (both before and after topical decongestion) (P < 0.05), except for the VAS on the right side of the nasal cavity before decongestion (P > 0.05). On acoustic rhinometry test the difference was statistically significant for minimal cross-sectional area (MCA) and volumetric values (VOL)-MCA1, MCA2, VOL1, VOL2 values on the left side of the nasal cavity (both before and after topical decongestion) (P < 0.05) but not on the right side of the nasal cavity (P > 0.05).

CONCLUSIONS

Performing spreader graft technique in SRP surgery can prevent the narrowing of the internal nasal valve area after surgery and maintain adequate airway for respiration.

Assessment of Functional Rhinoplasty with Spreader Grafting Using Acoustic Rhinomanometry and Validated Outcome Measurements

BACKGROUND

Rhinoplasty is 1 of the most common aesthetic and reconstructive plastic surgical procedures performed within the United States. Yet, data on functional reconstructive open and closed rhinoplasty procedures with or without spreader graft placement are not definitive as only a few studies have examined both validated measurable objective and subjective outcomes of spreader grafting during rhinoplasty. The aim of this study was to utilize previously validated measures to assess objective, functional outcomes in patients who underwent open and closed rhinoplasty with spreader grafting.

METHODS

We performed a retrospective review of consecutive rhinoplasty patients. Patients with internal nasal valve insufficiency who underwent an open and closed approach rhinoplasty between 2007 and 2016 were studied. The Cottle test and Nasal Obstruction Symptom Evaluation survey was used to assess nasal obstruction. Patient-reported symptoms were recorded. Acoustic rhinometry was performed pre- and postoperatively. Average minimal cross-sectional area of the nose was measured.

RESULTS

One hundred seventy-eight patients were reviewed over a period of 8 years. Thirty-eight patients were included in this study. Of those, 30 patients underwent closed rhinoplasty and 8 open rhinoplasty. Mean age was 36.9 ± 18.4 years. The average cross-sectional area in closed and open rhinoplasty patients increased significantly (P = 0.019). There was a functional improvement in all presented cases using the Nasal Obstruction Symptom Evaluation scale evaluation.

CONCLUSIONS

Closed rhinoplasty with spreader grafting may play a significant role in the treatment of nasal valve collapse. A closed approach rhinoplasty including spreader grafting is a viable option in select cases with objective and validated functional improvement.

Update in the management of the middle vault in rhinoplasty

PURPOSE OF REVIEW

The middle vault of the nose continues to be a topic of interest among surgeons interested in aesthetic and functional rhinoplasty. The purpose of this review is to present currently accepted concepts regarding the significance of the middle vault of the nose in rhinoplasty and to review the more frequently advocated methods to be used in the correction of deficiencies.

RECENT FINDINGS

Spreader grafts may be at least as effective as flaring sutures in improving the airway. Studies have shown an improvement in quality of life and nasal breathing with the use of autospreader flaps. The correlation between acoustic rhinometry and clinical symptoms of nasal obstruction, however, has fallen short of providing clear diagnostic value.

SUMMARY

The diagnosis of middle vault collapse and nasal valve obstruction remains largely clinical. The patient's reported symptoms of nasal obstruction are diagnostically considered along with the findings of clinical examination, including the findings of a modified Cottle maneuver.The use of spreader grafts and autospreader flaps has been popularized to correct problems in the middle vault of the nose and will be presented in detail in this manuscript.

Early Results and Description of a New Modification of Spreader Graft to Enlarge Nasal Valve Area: Modified Triangular Spreader Graft

OBJECTIVE

Nasal valve area is an important, functional part of nose and there are several different methods that have been used to enlarge that area for a better breathing function. In this study, the authors aimed to study the efficacy of a new spreader graft modification that was crafted in a triangular shape to enlarge nasal valve area.

METHODS

Twenty-two patients who underwent rhinoplasty operation with this new technique composed the study group. Average age of patients was 21.4 ± 2.1, 13 of them were men (59%) and 9 of them were women (41%). Same surgeon operated all 22 patients with the same technique that included usage of modified triangular spreader graft. Surgical outcomes were assessed by visual analog scale and nasal obstruction symptom evaluation scale preoperatively and 3 months postoperatively.

RESULTS

None of the patients had complications or aesthetic deformities according to surgeon after surgery. Average of nasal obstruction symptom evaluation scale score was 64.3 before surgery which reduced to 17.9 at postoperative third month. Also average visual analog scale score was 2.6 before surgery and it was 8.1 3 months after surgery indicating a better breathing sensation (P < 0.001).

CONCLUSIONS

Modified triangular spreader graft usage is a safe and effective method to enlarge nasal valve area with satisfactory aesthetic outcomes and good functional results because of its compatibility with anatomic position of nasal valve area.

Uses of Various Grafting Techniques in External Approach Rhinoplasty: An Overview

The surgeons performing rhinoplasty found Graft selection the greatest challenge. To avoid an immune response the preferred choice thus far for nasal reconstruction would be autograft compared to allograft due to its lower rate of rejection. We have evaluated 30 patients who underwent open rhinoplasty and We used conchal and septal cartilaginous grafts in various forms by the open approach to correct various nasal deformities compared our experience regarding the operative technique, graft availability, indications, and limitations. No bony graft material or synthetic materials were used. Preoperative extensive evaluation of the patient was done in order to determine the type of deformity and the type of graft to be used in order to correct the deformity. Preoperative and postoperative photographs were taken in four basic views: frontal, lateral, lateral-oblique and basal in order to assess the results of the surgery. The study was done on 30 patients (20 male and 10 females) using the external rhinoplasty approach using the septal and conchal cartilages in different forms. Autologous septal cartilage was used in most of the patients (25 out of 30) and conchal cartilage was used in 5 patients. Multiple grafting techniques were used in some patients. Three patients had traumatic etiology. Columellar strut graft along with TIG technique was used in 16 patients, spreader graft was used in 8 patients, and septal extension graft was used in 5 patient and shield graft in 1 patient. Septorhinoplasty continues to evolve through various new techniques and modifications with the main goal to improve functional nasal airway and to restore cosmetic harmony to the face. Optimum result is very much dependent on the surgeon's attention to functional, aesthetic, and reconstructive principles and graft selection.

Comparison of Aesthetic and Functional Outcomes of Spreader Graft and Autospreader Flap in Rhinoplasty

BACKGROUND

Although the assignment and suturing of the spreader graft to the septum is a routine part of rhinoplasty, it is a time wasting procedure and some problems may occur. Rather, autospreader flap is a new method that the dorsal part of the upper lateral cartilage is used as its own graft. In the present study, we intended to compare the functional and aesthetic outcomes of these two techniques of rhinoplasty.

METHODS

In a clinical trial, patients who referred to 15 Khordad Hospital for elective rhinoplasty during 2013-2014 were enrolled. The functional and aesthetic outcomes were compared between the two techniques of spreader graft and autospreader flap using rhinomanometry and satisfaction questionnaire in two stages before and one months after the surgery.

RESULTS

Total nasal airway resistance increased significantly by both spreader graft and autospreader flap, but the difference between the two methods was not statistically significant. The total nasal flow before and after the surgery significantly decreased using both techniques, but this reduction was not significant between the two methods of surgery. When questioned about the satisfaction with the surgery outcomes, 18 subjects (36%) had complete aesthetic satisfaction, 25 (50%) were partial satisfied and 7 subjects (14%) were unsatisfied from aesthetic results. The rate of patient's satisfaction in both groups was higher for functional outcome. Overall, 32 (64%) subjects were completely satisfied, 13 (26%) were partially satisfied and 5 (10%) subjects did not report satisfaction. Loss of respiratory function in both groups was inevitable due to short time post-operative period.

CONCLUSION

Both spreader graft and autospreader flap techniques can be used in the preservation and restoration of the normal internal nasal valve angle, as well as restoration of dorsal aesthetic lines of the nasal dorsum.

Update on the evidence for functional rhinoplasty techniques

PURPOSE OF REVIEW

Functional rhinoplasty is a term that is commonly used to describe any technique used to address nasal obstruction in the nasal valve region. The cause of nasal valve collapse differs based on the site. Internal valve collapse may be idiopathic or associated with previous rhinoplasty, trauma, or weakened cartilage in older patients. External valve collapse is usually idiopathic and less likely to be associated with previous surgery. Various techniques have been developed over time, and the data in support of functional rhinoplasty continue to increase.

RECENT FINDINGS

This article discusses popular techniques currently in use, as well as newer techniques that have been described over the past several years. In addition, there is a trend toward utilizing objective testing and validated assessment scales to assess postoperative changes.

SUMMARY

Functional rhinoplasty utilizes a multitude of techniques to address nasal valve collapse. Although high-level data are lacking, the current literature is in support of nasal valve correction to improve nasal breathing. Most importantly, the technique employed is unique for each patient.

Effects of Spreader Grafts on Olfactory Function in Septorhinoplasty

BACKGROUND

Following rhinoplasty, the cross-sectional parts of the nose may be significantly reduced, and nasal air movement and olfaction may be altered. Studies on olfactory function after surgical procedures are quite limited and have largely focused on sinus surgery or septoplasty.

OBJECTIVES

The objective of this study is to assess the consequences of spreader grafts on olfactory function.

METHODS

This prospective study was conducted at the Gaziosmanpaşa Taksim Education and Research Hospital, Department of Otolaryngology, from January 2014 to June 2015. In total, 68 patients who had undergone an open-technique septorhinoplasty were included. In 35 patients, bilateral spreader grafts were included with the open septorhinoplasty (group 1), and 33 patients underwent open septorhinoplasties without spreader grafts (group 2).

RESULTS

The age and gender distributions of the patients in the two groups did not differ (p > 0.05). Preoperative threshold, discrimination, and identification values in both groups did not differ (p > 0.05). In groups 1 and 2, postoperative threshold values were significantly higher than preoperative values (p < 0.05). The change in threshold, discrimination, and identification level was significantly higher postoperatively versus preoperatively in group 1 (p < 0.05); however, the changes in discrimination and identification values did not significantly differ between in group 2 (p > 0.05).

CONCLUSIONS

Our study demonstrates the superior widening effect of spreader grafts over the nasal valve and favorable results in olfactory function in primary septorhinoplasty patients.

Impact of osteotomies and structural grafts in the management of severe twisted or deviated nasal deformity: a critical analysis of 179 patients with open rhinoplasty

The aim of this study was to analyze the long term impact of different surgical techniques especially osteotomies and structural grafts especially spreader grafts in terms of functional and aesthetic outcomes in cases of severely deviated nose deformities using open structure rhinoplasty. Retrospective chart reviews of two hundred consecutive patients who underwent corrective rhinoplasty during the period between January 2009 and December 2010 for deviated nasal deformity were performed. Those cases which were done with closed approach (21) were excluded from the study. Analysis included 179 patients, with 136 males and 43 females, and 79.9% had history of trauma pre-operatively. Follow-up period was 6-24months out of which 88.4% were satisfied with the surgery results functionally and aesthetically. There was a statistical significant correlation between omitting osteotomy or using unilateral osteotomy and risk of recurrence or remnant deformity (p value 0.006). Similarly there was also a statistically significant relation between recurrence and placement of unilateral or bilateral spreader graft (p value 0.47). Our results of open approach are considered excellent. There is a significant relation between use of procedures like selection of osteotomies and non-use of spreader graft and the possibility of recurrence. Open structure approach provides improved functional and aesthetic results.
