Techniques for Diced Cartilage with Deep Temporalis Fascia Graft

Promotion of diced cartilage survival and regeneration with grafting of small intestinal submucosa loaded with urine-derived stem cells

Cartilage absorption and calcification are prone to occur after the implantation of diced cartilage wrapped with autologous materials, as well as prolong the operation time, aggravate surgical trauma and postoperative pain during the acquisition process. Small intestinal submucosa (SIS) has suitable toughness and excellent degradability, which has been widely used in the clinic. Urine-derived stem cells (USCs), as a new type of stem cells, have multi-directional differentiation potential. In this study, we attempt to create the tissue engineering membrane material, termed USCs-SIS (U-SIS), and wrap the diced cartilage with it, assuming that they can promote the survival and regeneration of cartilage. In this study, after co-culture with the SIS and U-SIS, the proliferation, migration and chondrogenesis ability of the auricular-derived chondrocyte cells (ACs) were significantly improved. Further, the expression levels of chondrocyte phenotype-related genes were up-regulated, whilst that of dedifferentiated genes was down-regulated. The signal pathway proteins (Wnt3a and Wnt5a) were also participated in regulation of chondrogenesis. In vivo, compared with perichondrium, the diced cartilage wrapped with the SIS and U-SIS attained higher survival rate, less calcification and absorption in both short and long terms. Particularly, USCs promoted chondrogenesis and modulated local immune responses via paracrine pathways. In conclusion, SIS have the potential to be a new choice of membrane material for diced cartilage graft. U-SIS can enhance survival and regeneration of diced cartilage as a bioactive membrane material.

Immediate Nasal Reconstruction in Management of Infected Nasal Alloplast and Allografts: A Case Series

BACKGROUND

The use of alloplastic and allogenic nasal implants is widely popular in rhinoplasty. However, the use of these materials is accompanied by a risk of infection and extrusion. Traditionally, management of these complications is performed in a dual-staged fashion. First, the implant is removed and infection is controlled, then a delayed reconstruction is performed. However, scarring and soft tissue contracture make a delayed reconstruction challenging, and optimal aesthetic outcomes are difficult to achieve. This study was designed to evaluate the outcomes of immediate nasal reconstruction following removal of an infected nasal implant.

METHODS

A retrospective chart review was performed of all patients who had infected nasal implants and underwent simultaneous removal and immediate nasal reconstruction with autologous cartilages (n = 8). Data collected included patient age, race, pre-operative presentation, intraoperative surgical maneuvers, and post-operative outcomes and complications. Post-operative results were used to measure success of the single-staged method.

RESULTS

Follow-up ranged from 12 to 156 months with mean 84.4 months of the eight patients who were evaluated in the study, none had any major post-operative complications that required revision or reconstruction. All of the patients had marked improvement in nasal form and function. Six of the eight (75%) patients reported excellent aesthetic outcomes; two (25%) requested revisional surgeries for aesthetic concerns.

CONCLUSION

Low complication rates and excellent aesthetic outcomes are possible in immediate autologous reconstruction following removal of an infected nasal implant. This is an alternative approach that obviates the inherent problems of a traditional delayed reconstruction.

Ethnic rhinoplasty: Preliminary results of our technique in the pursuit of the harmonious nose

INTRODUCTION

According to the American Society of Plastic Surgery, cosmetic surgery procedures for "ethnic patients" are annually increasing. Ethnic rhinoplasty traditionally represents a difficult challenge for plastic surgeons. Herein, we describe our personal technique to ethnic rhinoplasty to achieve a harmonious nose maintaining the characteristics of individual ethnicity and identity.

MATERIALS AND METHODS

In this study, we retrospectively reviewed ethnic patients treated with rhinoplasty at our institution between January 2019 and October 2022. We described our personal rhinoplasty technique step by step. At a minimum follow-up time of six months, postoperative pictures were taken, and patients were reassessed, evaluating aspects such as global symmetry and shape and contour of the nose. Finally, patient satisfaction was investigated according to rhinoplasty outcomes evaluation (ROE) questionnaire.

RESULTS

A total of 1321 patients were included in the study. They reported a significant satisfactory aesthetic result in nasal image, as indicated by the mean postoperative ROE score (92.12). No cases of nasal contracture were recorded. None of the grafts was extruded or collapsed. Wounds healed without reported major infection.

CONCLUSION

This study demonstrated that our approach is a safe procedure that contributes to improved functional outcomes with a high patient satisfaction rate and a low rate of postoperative complication. The creation of a solid base structure, nasal skin preparation, and an integrated patient approach are key elements of this surgery.

Closure of Nasal Septal Perforations Using a Diced Cartilage in Fascia Graft

The spectrum of surgical techniques in the repair of nasal septal defects is wide. The objective of this study was to assess the feasibility of using a diced cartilage in fascia (DC-F) graft for successful closure of nasal septal perforations and to evaluate symptom reduction. This was a retrospective study of 18 patients undergoing surgical repair of symptomatic nasoseptal perforations of different etiologies using a DC-F graft from 2020 until 2021. The procedure was feasible in all of the 18 patients. Reconstruction of septal defects with a DC-F graft led to reduction of crust formation, reduction of epistaxis, and improvement of nasal breathing in 13 out of the 18 patients when seen for their 2-month follow-up. Reperforation occurred in three cases, leaving defects of 1, 7, and 5 mm in diameter. In one case, the reperforation was symptomatic. A DC-F graft proved to be a reliable and reproducible method for the closure of nasoseptal perforations of variable sizes, of different locations, and of different etiologies.

Dorsal Augmentation

To manage the deficient nasal dorsum, a thorough knowledge of dorsal augmentation techniques should be mastered by the rhinoplasty specialist. Indications for dorsal augmentation may arise in both primary and revision rhinoplasty presentations. To direct operative planning, a complete facial analysis, noting the importance of maintaining overall nasofacial balance, is essential. An array of techniques, including autologous and nonautologous (ie, allogeneic and synthetic) sources, have been used globally-each carrying its own advantages and disadvantages. The authors believe autologous grafts to be the optimal source for dorsal augmentation because of their biocompatibility and ability to produce natural and long-lasting outcomes.

Treatment of the Crooked Nose

The crooked nose is a challenging esthetic and functional problem. The surgeon must carefully evaluate baseline facial asymmetry as well as whether deviation stems from the upper third, middle third, or lower third of the nose. Surgical intervention should be tailored accordingly, with techniques geared toward addressing each deviated section. Modified dorsal preservation techniques represent a newer means to address deviations. Operative results must be measured, ideally through patient-reported outcomes measures, to quantify overall success.

Rhinoplasty: Aesthetic Augmentation With Improvement of Dorsal Aesthetic Lines

BACKGROUND

Camouflage of nasal dorsum, aesthetic augmentation, and highlighting the dorsal aesthetic lines are essential elements in modern rhinoplasty. Numerous techniques have been utilized, including deep temporal fascia, rectus abdominis fascia, and diced cartilage in fascia (DC-F). Despite their widespread adoption, technical challenges remain, especially when utilized for aesthetic purposes.

OBJECTIVES

This paper details the utilization of fascia and DC-F for aesthetic dorsal refinement in primary and secondary cases. One of the main goals was to achieve ideal dorsal aesthetic dorsal lines rather than just volume augmentation.

METHODS

The authors employed grafts from the deep temporalis fascia and rectus abdominis fascia in 4 configurations: (1) single layer, (2) double layer, (3) full-length DC-F, and (4) partially filled segmental DC-F grafts. Technical refinements included careful determination of dimensions and meticulously suturing to the dorsum at appropriately 10 points to prevent graft displacement.

RESULTS

The authors report their experience with 146 clinical cases over 35 months from January 2017 to December 2019. The patients were divided for 4 groups depending on which type of graft was utilized.

CONCLUSIONS

Autogenous deep temporal fascia, rectus abdominis fascia, and DC-F were utilized to camouflage dorsal irregularities, highlight dorsal aesthetic lines, and aesthetically augment either the entire nasal dorsum or its individual parts. Optimization of cutting, stitching, filling the graft, and careful fixation of these grafts on the nasal dorsum significantly increases the predictability of these techniques and minimizes problems.

Double Columellar Strut: A New Method for Tip Surgery-A Study of 642 Cases with a 15-Year Follow-up

GOAL

Of the first nasal tip modeling procedures performed, the Anderson tripod concept is the most well known, and many anatomy-related studies have analyzed the components involved in tip surgery. The main goals of nasal tip surgery are to stabilize the tip complex, which largely affects the shape, projection and rotation of the nasal tip.

OBJECTIVE

The present study describes a new, original method, the double columellar strut and its main advantages compared to conventional techniques used for structural rhinoplasty.

METHODS

The study involved 642 patients (496 women and 146 men, with an average age of 38.67 years) who underwent surgery between 2004 and 2018 by two operators. The patients were re-examined to evaluate the outcomes at least 1 year after surgery, and long-term results (15 years) were recorded for the oldest patients in regard to esthetics (projection, shape, rotation) and breathing function.

RESULTS

Of the 642 patients, 34 required a surgical revision for minor defects of the tip due to asymmetry, and the natural appearance after the first surgery was not affected. For the primary rhinoplasties, there were no breathing disorders that required revision surgery due to systematic restoration or preservation of the middle third.

CONCLUSION

The double columellar strut could be performed in the same conditions that the others conventional structural grafts. As a polyvalent alternative, it can be used with closed or open approaches and involves the use of only a limited amount of cartilaginous material. This anatomical approach yields natural results, acting as a foundation for controlling the shape, projection and rotation of the nasal tip. In addition, with or without complementary techniques such as the "tongue-in-groove" technique or tip grafts, the double columellar strut can be considered a "multifunction pocket knife" for tip surgery.

The SPF-SPLF Graft: Building the Ideal Dorsum in Revision Rhinoplasty

Achieving a natural appearing dorsum in secondary rhinoplasty remains an elusive goal. An inherent contradiction exists between the two most usually used techniques: solid rib segment and diced cartilage fascia constructs. The former will often cause edge visibility, in addition to potential warping and distortion; the latter prevents from both but may generate obtuse, ill-defined borders with poor shape control, possible contour asymmetries, and often a tubular appearance. A solution to the equation can be found in an innovative technique that combines three elements: perichondrium, rectus fascia, and a rib lamination. The combination is called the sandwich of perichondrium and fascia (SPF) or the sandwich of perichondrium, rib lamination, and fascia (SPLF). As a single unit over the entire dorsum, the issues of junction irregularity inherent in the use of separate graft segments, and of asymmetries in the dorsal contour because of inadequate distribution of diced cartilage, are avoided. In a greater than 18-month experience on 23 cases at the time of writing, the SPF-SPLF graft has proved to be an ideal solution. Adequate edge definition and elegant related shadowing are provided, precise tailoring is attained, and proper height of the dorsum contour is reestablished, following adequate reconstruction of the underlying dorsal plateau. The gradual flow from SPF to SPLF is logical and progressive according to need, and proper fixation ensures long-term stability of the hybrid construct. All three elements required are harvested from the same donor site with a resulting minimal scar.

Comparison of Patient Satisfaction Between Composite and Dorsum Augmentation-Only Nasal Reconstructions With Diced Cartilage Graft Wrapped in Fascia

The comparison of patient satisfaction with the use of diced cartilage graft wrapped in fascia (DCF) graft in composite versus dorsum augmentation-only reconstructions (DAOR), technical hints and complications in our series, affecting the end-result and the patient satisfaction (PS) has been presented.Between 2013 and 2018 the DC-F graft is used in 32 rhinoplasty cases. Nine of patients have had composite reconstruction (CR). The DAOR has been needed for 23 of patients.The follow-up period has been 2 months to 3 years. The authors have obtained satisfactory results in 24 cases but some untoward progress in 8 cases. A questionnaire was prepared and asked all patients for the assessment of the satisfaction from appearance, breathing, self-esteem, and positive psychological effect.The learning curve for rhinoplasty should be calculated for, hump reduction, crooked nose, augmentation rhinoplasty, and so on. separately which is also relevant for the use of a DC-F graft. Placing the DC-F over a straight platform, choosing the accurate graft and fascia material wisely, proper tailoring of DC-F, sliding it under the skin-superficial musculoaponeurotic system properly etc. determine the quality of the end result and the degree of PS. Operating on the DAOR are relatively more comfortable compared to CRs but responses to our questionnaire denote higher degrees of satisfaction in CR cases.Utilization of the DC-F graft in secondary rhinoplasties for dorsum augmentation provides satisfactory results. The degree of PS with the DC-F reconstruction seems to have an adverse correlation with the extent of deformities that you start with.

A Modified Suction-Assisted Technique of Transfer of Diced Cartilage Graft to Carrier Material and Outcome of Direct Injection of Unwrapped Diced Cartilage in Rhinoplasty

OBJECTIVE

To describe a modified suction-assisted technique (MSAT) of transfer of diced cartilage (DC) graft to a carrier material and to determine the clinical outcome of direct injection of unwrapped diced cartilage (UDC) in rhinoplasty.

PLACE AND DURATION OF STUDY

Department of Plastic Surgery, KEMU, Mayo Hospital, Lahore from February 2011 to January 2015 METHODS:: Forty-seven patients of both genders with types 0 to 3 saddle nose deformity were included. Patients with types 4 and 5 saddle nose deformity, diabetes, hypertension, hepatic or renal disorders were excluded. Open tip rhinoplasty was performed in all patients. Eighth and/or ninth costal cartilage was harvested. Cartilage graft was diced into 1 to 2 mm pieces. The DC graft was transferred to carrier material (1-mL syringe) with MSAT. The UDC was then injected into nose and clinical outcome was determined.

RESULTS

Out of 47 patients included in the study 62% were females with mean (standard deviation [SD]) age 22 (4) years. Thirty-four (72%) procedures were primary rhinoplasties while 13 (28%) were secondary rhinoplasties. Mean (SD) carrier material filling time was 12±3 seconds. All operating surgeons involved in study were satisfied with modified suction technique and declared it better than the traditional manual technique of filling the carrier material. Most of the patients were satisfied with their postoperative nasal appearance and complications were minimal. One patient required revision of surgery due to dorsal contour irregularities and another due to partial cartilage absorption at 13 ± 2 months follow-up.

CONCLUSION

Our MSAT of transfer of DC and injection of UDC is simple, easy to perform, reduces operative time and produces acceptable cosmetic outcome as regard patient's satisfaction.
