Rhinoplasty using rib chondro-osseous graft in Asian patients

Aesthetic Outcome of Primary Rhinoplasty of Saddle Nose Deformity in Naso-Orbital Ethmoidal Fractures in Asian Patients

BACKGROUND

Saddle nose deformity following naso-orbital ethmoidal (NOE) fractures remain a challenging problem for the reconstructive surgeon. Early reduction and internal fixation allow for fracture stabilization but is unable to address the problem of the depressed nasal dorsum, especially after soft tissue shrinkage. The aim of this study is to evaluate the outcome of primary rhinoplasty in patients with NOE fractures.

MATERIALS AND METHODS

From 2016 to 2019, 9 patients presented to our department with NOE fractures complicated by saddle nose deformity underwent primary nasal reconstruction at the time of their fracture fixation. Life size (1:1) frontal and lateral postoperative photographs were taken. Three objective measurements were made, including the nasofrontal angle, tip projection, and radix projection. These measurements were compared between normal persons (group 1), preoperative patients (group 2), and postoperative patients (group 3). Nose aesthetic assessment was carried out via a panel assessment using a Visual Analog Scale of 5. Patient satisfaction was further assessed subjectively by the patient themselves using the Visual Analog Scale.

RESULTS

When comparing group 3 to 2, a significant reduction in the nasofrontal angles was found with an accompanying increase in the radix and tip projection ( P <0.05). No statistical significance between normal persons and postprimary rhinoplasty patients was noted between groups 1 and 3. Average patient satisfaction scored 3.86±1.07 compared with 3.63±0.84 by laypersons and 4±0.77 by specialists' panel.

CONCLUSION

Primary nasal reconstruction may be an alternative method for achieving optimum results following NOE fractures preventing the development of secondary saddle nose deformity with a shortened nose which may potentially be more difficult to correct.

Complications of the nasal dorsum reconstruction using autologous or alloplastic grafts: evidence from systematic review and meta-analysis

INTRODUCTION

Augmentation rhinoplasty depends mainly on intact stable bony and cartilaginous parts. Many trials have used different materials as a graft to perform the operation and support the nose. Debate exists whether alloplastic or autogenic grafts are more appropriate. Common available alloplastic grafts include silicone, medpor, and gore-tex. Autogenic grafts are usually derived from costal cartilages. Warping, infection, and hypertrophic scars are the main complications of the procedure. Yet no subgroup analysis has been performed to investigate the effect of different risk factors.

OBJECTIVE

To investigate the effect of different types of grafts and the association of the income level of the country on surgery complications.

METHODS

A comprehensive literature search of articles was conducted in PubMed, Cochrane Library, Web of Science, and SCOPUS databases through October 2019. We included articles that used autologous or alloplastic grafts in nasal dorsum reconstruction surgery. We performed subgroup analysis according to the type of graft used, region, and income level of the country. A meta-regression analysis model was carried out from the period of 1999-2018, to study the incidence of these complications over time.

RESULTS

The overall complication rate was 7.1%, which was higher in the alloplastic group (7.8%) than the autogenic group (6.9%). The most common complications were secondary surgery for re-correction (4.1%), infection (2.1%), warping (1.6%), and hypertrophic scars (1.6%). All outcomes were homogeneous (I2 < 50%).

CONCLUSION

Patients with autogenic grafts are less liable to develop complications than their peers reconstructed with alloplastic grafts. Moreover, Asian patients are less susceptible to overall rhinoplasty complications. Attention should be noted for low-income countries in which surgical complications are more prone to occur.

Can Oblique Sliced Method Avoid Warping?

Warping is the most important problem of costal cartilage grafts used in secondary rhinoplasties. The aim of this study is to show that costal cartilage grafts prepared with oblique sliced method (OSM), can solve the warping problem and provides successful results in both functional and aesthetic appearance. There are 42 patients who had previous nose surgery and dissatisfied with their facial appearance included in the study to perform secondary rhinoplasty with costal cartilage graft OSM technique. The outcomes of the operations were performed objectively using facial measurements and subjectively using rhinoplasty outcomes evaluation (ROE) scale, before and 12 months after the operation. The mean of total ROE score was 8.171 ± 3.285 on the pre-operative period and it was increased to 19.11 ± 3.652 where the P value was found to be <0.0001. And the post-operative 12th month period all values of nasal dorsal angulation was lower then 1° and the mean of angulation degrees was 0.224° with the minimum value 0.000° and maximum value 0.801°. The study revealed the outcome of rhinoplasty which done by OSM was statically significant both subjective patient's satisfaction and objective facial measurements. The authors suggest using of OSM in secondary rhinoplasties because the graft can be easily prepared with the desired thickness and carved into different shape without risk of warping.

Posttraumatic Augmentation Rhinoplasty Using an Osseocartilaginous Cantilever Graft

BACKGROUND

Augmentation rhinoplasty in Asians may be effectively accomplished with alloplastic materials. However, certain circumstances such as nasal bone fractures mandate the use of autologous grafts. The purpose of this study was to describe and evaluate the results of modified osseocartilaginous rib cantilever grafting for aesthetic and reconstructive rhinoplasty in patients with acute nasal bone fractures.

METHODS

Forty-three patients with nasal bone fracture underwent surgical reconstruction with an autogenous rib graft. Anatomic reconstruction and dorsal augmentation were performed using 1 piece of a carved osseocartilaginous rib graft each for the bony and cartilaginous parts of the nose. The average time to surgery was 6.5 days, and patient's subjective satisfaction was scored.

RESULTS

"Excellent" or "good" cosmetic outcomes were reported by 37 patients (86%). There were 3 cases of secondary revision. Donor-site morbidity was not an issue in any patient.

CONCLUSIONS

Anatomic reconstruction of the nasal dorsum and refining the nasal tip using an osseocartilaginous rib graft with the cantilever technique are effective in acute nasal trauma patients who wish to enhance their nasal profile in the primary treatment setting.

Primary aesthetic correction of nasal anomaly with costal graft in treating orbital hypertelorism

Orbital hypertelorism is a common congenital craniofacial anomaly in Asians. As Tessier pointed out, the correction of hypertelorism is effectively the correction of the nasal deformity, which is characterized by a broad, flat nose accompanying an increased interorbital distance and a lack of nasal projection.

OBJECTIVES

To measure the changes in the orbital and nasal parameters after Tessier box osteotomy and primary aesthetic rhinoplasty, performed concurrently with otogenous costochondral graft.

METHODS

From 2009 to 2013, 49 hypertelorism patients were treated in our craniofacial unit. Correction involved a classic Tessier box osteotomy combined with aesthetic augmentation and reconstruction of the nasal dorsum using a costochondral graft. All patients underwent photographic and tomographic documentation both before and 12 months after surgery. Patients underwent morphometric analysis to document the change in interorbital distance, IOD, hypertelorism index, and aesthetic nasal parameters, including the nasal dorsum and alar width, the nasal dorsal height, and the index of nasal apex protrusion versus nasal length.

RESULTS

All patients were satisfied with the outcome of the combined orbital and nasal repair. Morphometric analysis indicated that the IOD, hypertelorism index, and aesthetic nasal parameters all improved following surgery. The resorption rate of the costochondral graft was 16-19%, and graft warpage was nearly absent. Although complications included infection, cerebrospinal fluid leak, and hyposomia, no severe or life-threatening complications occurred.

CONCLUSION

Tessier box osteotomy with primary aesthetic rhinoplasty using costochondral grafts has shown to be efficacious in the treatment of patients with hypertelorism.

Sliced Costochondral Chip Grafts in Posttraumatic Enophthalmos Correction

BACKGROUND

Posttraumatic enophthalmos is a relatively common problem following orbitozygomatic fractures. However, inadequate long-term results are frequently observed due to the difficulty of performing intraoperative fine adjustments to soft-tissue volume and orbital size and gradual absorption of some grafted materials. Here, the authors describe an efficient method of enophthalmos correction using sliced costochondral bone and cartilage combination grafts.

METHODS

From 2005 to 2011, the authors corrected enophthalmos in 12 patients using sliced costochondral grafts. The mean follow-up period was 13 months. For costochondral graft harvest, an approximately 5-cm skin incision was made directly above the seventh costal cartilage, the perichondrium was peeled back, and a small piece of rib bone and costal cartilage was harvested from the anterior part of the seventh rib bone and cartilage and cut into 2-mm-thick slices. A subciliary and/or transcaruncular incision was made in the affected side eyelid to expose the operating field, subperiosteal dissection was performed in the orbit and orbital floor. The cartilage chips were gradually grafted onto the dissected areas from the posterior orbit.

RESULTS

Aesthetically satisfactory results were obtained in all patients. No complications in the donor area were observed. Furthermore, no patients experienced a recurrence or deterioration of diplopia over the follow-up period. One patient experienced temporary high intraocular pressure, which spontaneously resolved with medication and eye drops.

CONCLUSION

The costochondral graft is adequate for the reconstruction of the fracture, easy to obtain, easily adaptable to the orbital walls, and has minimal morbidity at the donor site.

Augmentation rhinoplasty using a folded "pure" dermal graft

BACKGROUND

Although there are several reports about the use of dermal or dermofat grafts, there are only a few reports about augmentation rhinoplasty performed using a "pure" dermal graft. Authors introduce the refined techniques, clinical experience, and report an aesthetically pleasing result of augmentation rhinoplasty performed using a folded pure dermal graft.

MATERIALS AND METHODS

Between 2008 and 2012, augmentation rhinoplasty was performed in 68 cases using a folded pure dermal graft. Pure dermal graft was harvested from one side of the buttock close to the intergluteal crease and the graft length was approximately 7-8 cm and the graft width was 1.5-2 cm, and the epidermis and fat were completely removed. Tip-plasty was performed using a conchal or septal cartilage as a columellar strut and an onlay graft. Pure dermal grafts are folded into 2 layers and sculpted to the desired size and shape, and are inserted into the supraperiosteal pocket. Ultrasonography was performed to know the absorption rate of the folded pure dermal grafts.

RESULTS

The thickness of a dermal graft at postoperative 12 months was 60.3% of that at postoperative 1 month. Even with 39.7% of reduction in the thickness of the dermal graft, the height of nasal dorsum after postoperative 1 year is considered to be well maintained. Among the 68 cases that underwent augmentation rhinoplasty (43 primary and 25 secondary), most of the patients sustained consistent cosmetic results; however, 12 patients (17 %) showed over-absorption, under-absorption or contour irregularity of the dermal graft, and slight erythema. There were no aesthetically or medically serious problems needing secondary rhinoplasty such as hematoma formation, warping of the graft, graft extrusion, infection, and rejection of the graft.

DISCUSSION

Augmentation rhinoplasty using a folded pure dermal graft has many advantages and is a very useful surgical option in patients who have an aversion to the use of artificial implants, who want to change the postoperative appearance of their nose due to insertion of an artificial implant into a more natural appearance, and when there is too much thinning of the skin due to repeated insertion of silicone implants.

Use of osseocartilaginous paste graft for refinement of the nasal dorsum in rhinoplasty

In both primary and secondary rhinoplasty, establishment or refinement of nasal dorsal aesthetic lines is of paramount importance. Many different techniques used to create a cosmetically acceptable nasal dorsum have been published. The material to be used in nasal dorsal contouring should create a harmonic contour and should be easily shaped, long-lasting, and resistant to infection. Resection of the hump yields an osseocartilaginous complex as a single unit when an osteotome is used. Use of a rasp gives a good amount of fragmented material comprising bone, cartilage, soft tissues, and blood. The authors used this material as a paste graft to refine the nasal dorsum in rhinoplasty and retrospectively evaluated the outcomes. A retrospective chart review of 77 patients who underwent this procedure between 2003 and 2009 was performed. The follow-up period ranged from 22 to 40 months (median, 28 months). The postoperative evaluations included clinical examination and digital photographic documentation. The satisfaction of each patient was assessed with a questionnaire completed at the 12th postoperative month. The described graft, which combines the advantages of cartilage and bone, was shown to be clinically durable. This combination also results in an ideal texture and consistency for molding due to its diced form. The texture of this graft enables the surgeon to give a final shape to the nasal dorsum bimanually. In this study, a paste graft was shown to be a versatile and reliable composite material for nasal dorsal contouring and refinement.

Determining the most suitable costal cartilage level for rhinoplasty: an experimental study

OBJECTIVE

The aim of this study was to compare the biomechanical properties of septal cartilage (SC) and costal cartilage (CC) grafts harvested from different ribs and to find at which level CC has characteristics closest to SC.

STUDY DESIGN

Experimental cadaver study.

SETTING

Istanbul Training and Research Hospital.

MATERIAL AND METHOD

Cartilage grafts were harvested from the 6th, 7th, and 8th ribs and the SC of 10 fresh cadavers. Shaped cartilage grafts were subjected to a bending test. Results were measured, and the force-deflection curve was plotted. Flexural strength (σ(f)) and flexural modulus of elasticity (E(f)) were determined. Fractured surfaces were evaluated by scanning electron microscopy (SEM).

RESULTS

According to F(max), it was determined that ribs 6, 7, and 8 have significantly more durability compared with the SC (Ps = .030, .004, and .001). With regard to deflection, there was no significant difference between the SC and the 6th and 7th ribs and between the 6th and 7th ribs (Ps = 1.000, .088, and .306), while a significant difference was found between the SC and the 8th rib (P = .001). According to σ(f), no differences were seen between the 6th and 7th rib (P = .782), while difference was detected between the 6th and 8th and the 7th and 8th ribs (p = .001). Similar trends were established in E(f) values as in σ(f.) These results were confirmed by SEM images.

CONCLUSION

The 7th CC can be used as autograft because it shows similar properties to SC. However, the 6th CC is preferred if more flexibility is desired, and the 8th CC is preferred where more strength is needed.
