Lip enhancement: surgical alternatives and histologic aspects

The effects of VY closure on lip morphology after Le Fort I maxillary advancement: A systematic review

VY closure of the Le Fort 1 incision may commonly be indicated to mitigate the lip shortening effects of maxillary advancement. The objective of this systematic review was to investigate if VY closure prevents lip shortening when compared with conventional continuous closure (CS) methods, in patients who underwent le fort 1 maxillary advancement. PubMed, Embase, and Cochrane Library databases were accessed. Hand searching was also performed. Observational studies, non-randomised and randomized controlled trials were included if Le Fort 1 maxillary advancement was performed to correct a dentofacial deformity. Comparisons were made between VY and CS, and morphological changes to the upper lip were evaluated. The demographic data, study methodology, magnitude of maxillary movements and outcomes related to the lip morphology (length, vermillion exposure, thickness and angulation) were extracted. The search yielded 487 articles. Six studies were included after the application of the selection criteria. A total of 100 and 94 patients received CS and VY respectively. VY was not found to reliably prevent lip shortening. VY was more likely to mitigate lip shortening when there is a large maxillary advancement. It was consistent for a protrusive or "rolled-out" lip morphology to occur after a VY closure. This was demonstrated by the increase in lip vermillion exposure, thickness, and angulation. VY closure was a useful adjunctive technique in patients undergoing large maxillary advancements to mitigate the lip shortening effect from the procedure. Surgeons who employ this technique must also be aware of the consequence of a more protrusive lip with increased vermillion exposure and assess if this would be aesthetically desirable for the individual patient.

Utility of J-Shaped Scar Tissue-Based Flap for Secondary Bilateral Cleft Lip Repair: A One-Stage Procedure with Successful Outcomes on Correction of Vermilion Border, Volume Deficiency of Lip, and Muscular Function

This study aimed to evaluate the utility of J: -shaped scar-tissue-based flap as a new technique in secondary bilateral cleft lip reconstruction in patients with challenging secondary deformities. A total of 52 patients, comprising 38 males and 14 females with a mean age of 21.0 years (range: 16-42 years), who underwent secondary bilateral cleft lip repair operation via the J: -shaped scar tissue flap technique in our clinic between 2014 and 2019 were included. Postoperatively, patients were followed up for an average of 2 years (range, 6 months to 5 years) to assess the outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry, based on the Global Aesthetic Improvement Scale (GAIS), patient-reported outcomes, and independent plastic surgeons' examinations. After an average follow-up of 2 years, outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry were successful, and none of the patients experienced new notch formation, muscular functional loss, lip volume loss, or asymmetry. Owing to good muscular function preventing the stretching, the postoperative scars become more acceptable to the patients. The technique has proven to be safe and successful through the GAIS objective assessment, as also confirmed by the examinations of the three independent surgeons, while the majority of patients reported an exceptional improvement in the appearance alongside a more than 95% satisfaction rate with the operation. In conclusion, our findings revealed successful functional and aesthetic outcome of using J: -shaped scar tissue flaps in secondary repair of cleft lips. The technique was associated not only with the correction of significant secondary deformities yielding an improved and symmetrical lip volume, correction of vermilion notch, and prevention of notch re-formation but also with the restoration of orbicularis oris muscle function and thus integrity of the lip with minimal scarring.

A Comparison Between Hyaluronic Acid Filler and Dermofat Grafts With or Without Tie-Over Dressing for Lip Augmentation

BACKGROUND

There are many different autologous grafts used for lip augmentation, such as fat, fascia, or dermofat grafts (DFG). However, filling with synthetic materials such as hyaluronic acid (HA) fillers is the most preferred method.

OBJECTIVE

The authors aimed to compare DFG with HA fillers regarding cost, permanence, complication rate, gained volume, and satisfaction rate. The authors investigated the effect of tie-over dressings on the viability of DFG.

PATIENTS AND METHODS

Patients who received hyaluronic acid fillers were referred to as Group H. Patients who received grafts without tie-over and with tie-over dressings formed Groups D1 and D2, respectively. The lip index (LI) was used for volume comparisons. The viable area of the grafts was measured using ultrasound imaging.

RESULTS

At postoperative month 6, the only significant difference was found between Group D1 and Group D2 ( p < .05). At the postoperative first year, Groups D1 and D2 had a statistically higher LI value compared with Group H. Group D2 had a higher viable area than Group D2 ( p < .05). Group H and Group D2 showed higher satisfaction scores than Group D1 ( p < .05).

CONCLUSION

Dermofat grafts with or without tie-over dressings can be considered a reliable and inexpensive choice for patients who seek a more permanent procedure. Tie-over dressings increase the predictability of DFG and reduce the need for overcorrection.

Fat grafting in patients with cleft lip and palate: A systematic review

This systematic review aims to compare different fat-grafting techniques for cleft lip and palate repair. A search was conducted in PubMed, Embase, Cochrane Library, gray literature and reference lists of selected articles. A total of 25 articles were included, 12 on closure of palatal fistula and 13 on cleft lip repair. The rate of complete resolution of palatal fistula ranged from 88.6% to 100% in studies with no control group, whereas in comparative studies patients receiving a fat graft showed better outcomes than those not receiving a graft. Evidence suggests that fat grafting can be indicated for the primary and secondary repair of cleft palate, with good results. The use of dermis-fat grafts in lip repair was associated with gains in surface area (11.5%), vertical height (18.5%-27.11%), and lip projection (20%). Fat infiltration was associated with increased lip volume (6.5%), vermilion show (31.68% ± 24.03%), and lip projection (46.71% ± 31.3%). The available literature suggests that fat grafting is a promising autogenous option for palate and fistula repair and for improvement of lip projection and scar aesthetics in patients with cleft. However, to develop a guideline, further studies are needed to confirm whether one technique is superior to the other.

Surgical Treatment for Empty Nose Syndrome Using Autologous Dermal Fat: Evaluation of Symptomatic Improvement

Background: Empty nose syndrome (ENS) is caused by nasal turbinate surgery. The standard treatment for ENS is an inferior meatus augmentation procedure (IMAP) in which autologous tissue such as auricular cartilage, rib cartilage, or artificial material is transplanted into the nasal cavity. However, some challenges like a very small auricular cartilage are associated with these autologous tissue types. Moreover, since using rib cartilage is a highly invasive technique, the scar on the chest from where the harvesting is done is easily visible, and the artificial material is susceptible to infection. We used autologous dermal fat (ADF) in IMAPs in our study for the following reasons: the quantity of ADF could be increased or reduced as needed, ADF is considered a safer option than rib cartilage because it is harvested from superficial tissue, it is superior in terms of cosmetic appearance to harvested rib cartilage, and it has a lower risk of infection than any artificial material.Objective: The purpose of our study was to investigate the efficacy and safety of IMAPs using ADF.Methods: We included nine patients with ENS who underwent an IMAP using ADF. The patients' backgrounds and responses to the Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) were recorded. Changes in each item of the ENS6Q before and after surgery (up to 3 months) were analyzed.Results: The postoperative ENS6Q total score and parameters were significantly better than their preoperative counterparts. Nasal dryness improved slightly less than other symptoms. There were no complications.Conclusions: The IMAP using ADF was effective in improving ENS symptoms; however, some physiological functions were difficult to improve, and dryness persisted. Autologous dermal fat is larger than auricular cartilage, less invasive than rib cartilage, and has a lower risk of infection than artificial material.

Aesthetic Enhancement of the Vermilion Using Dermofat Graft in Patients With Cleft Lip Deformity

BACKGROUND

There is an increasing patient expectation for better esthetics, manifesting through anatomical harmony, projection, and volume of the upper lip relative to the lower lip, in patients with cleft deformity. The aim of this study is to investigate the outcome of vermilion augmentation using autologous dermofat graft (DFG) to enhance the lip using both quantitative and qualitative assessment.

METHODS

Patients with secondary cleft lip deformity who received the surgical treatment in our institution from 2015 to 2018 were recruited. Panel assessment was performed on standardized preoperative and postoperative digital photographs. A patient questionnaire was used for the reported outcome. Image processing and analyses were applied to measure the lip change. Statistical analyses were performed.

RESULTS

A total of 91 patients were included. The mean age at operation was 22.7 years, and postoperative follow-up was 3.6 years. There were no complications in the study group. The panel assessment showed significant improvement (P < .00001) on upper lip vermilion in both frontal and lateral profile views. Ninety-five percent of patients reported improvement of the upper lip projection and volume. Quantitative image analysis showed an increase in the upper lip vermilion ratio in 97% of the cases in frontal views and improvement of the vermilion projection in 87% of the cases in the superimposed lateral views.

CONCLUSIONS

The use of DFG is an effective and reproducible method for vermilion augmentation and aesthetic enhancement in patients presenting with upper lip insufficiency relative to the lower lip.

Precision Dermal Fat Grafting for Vermillion Deficiencies in Patients With Unilateral and Bilateral Cleft Lip

Objective:

Deficiencies of the upper lip vermilion occur with some frequency following repair of unilateral and bilateral clefts of the lip and can compromise the aesthetic outcome. The presence of dense scar tissue within the lip at the cleft site as well as intrinsic vermillion deficiencies can make long-lasting correction of this deformity challenging. We describe a technique to address vermillion deficiencies after cleft lip repair.

Design:

A novel lip augmentation technique for correction of residual vermilion deficiencies after unilateral and bilateral cleft lip repair is presented. This technique combines precise placement of a contoured dermal fat graft with local tissue (V-Y) rearrangement.

Conclusion:

In our experience, this method of lip augmentation following either unilateral or bilateral cleft lip repair can restore upper lip vermillion symmetry and provide predictable and durable results in patients with mild to severe vermillion deficiency.

Autologous Lipotransfer - Daily Therapeutic Practice in Breast Cancer: An Intergroup Analysis Encompassing NOGGO, WSG, GBG, AWO Gyn and DGPRÄC

Background

Autologous fat transfer in breast reconstruction has become increasingly important in breast reconstructive surgery. Although the indication to obtain fat, the various operative procedures, and the risks for the patient have been addressed in a large number of studies, detailed information on the everyday use of autologous lipotransfer in breast units in Germany is still lacking.

Methods

The objective of the study was to obtain primary data on the use of autologous lipotransfer to treat breast cancer patients in Germany and to determine measures for quality assurance in the daily practice. An online questionnaire concerning breast cancer and lipofilling was sent to specialists in gynecology and plastic surgery.

Results

Two-thirds of the specialists who responded to the questionnaire use autologous lipotransfer for breast reconstruction and did not report an increase of local recurrence following lipotransfer. There were only small differences between gynecologists and plastic surgeons regarding the procedure and indication for lipotransfer. The method is highly accepted by patients and physicians, and both gynecologists and plastic surgeons rated the improvement achieved through lipofilling as 'high'.

Conclusions

The lack of randomized controlled data, especially in high-risk patients, demonstrates the necessity for a registry study on this topic. Our survey describes, in detail, the indications for lipofilling as well as its appropriate application in breast cancer patients in Germany and may thereby reduce the present therapeutic uncertainties.

Perception of upper lip augmentation utilizing simulated photography

BACKGROUND

No head to head comparison is available between surgical lip lifting and upper lip filler injections to decide which technique yields the best results in patients. Despite the growing popularity of upper lip augmentation, its effect on societal perceptions of attractiveness, successfulness and overall health in woman is unknown.

METHODS

Blinded casual observers viewed three versions of independent images of 15 unique patient lower faces for a total of 45 images. Observers rated the attractiveness, perceived success, and perceived overall health for each patient image. Facial perception questions were answered on a visual analog scale from 0 to 100, where higher scores corresponded to more positive responses.

RESULTS

Two hundred and seventeen random observers with an average age of 47 years (standard deviation, 15.9) rated the images. The majority of observers were females (n=183, 84%) of white race (n=174, 80%) and had at least some college education (n=202, 93%). The marginal mean score for perceived attractiveness from the natural condition was 1.5 points (95% confidence interval [CI], 0.9-2.18) higher than perceived attractiveness from the simulated upper lip filler injection condition, and 2.6 points higher (95% CI, 1.95-3.24) than the simulated upper lip lift condition. There was a moderate to strong correlation between the scores of the same observer.

CONCLUSIONS

Simulated upper lip augmentation is amenable to social perception analysis. Scores of the same observer for attractiveness, successfulness, and overall health are strongly correlated. Overall, the natural condition had the highest scores in all categories, followed by simulated upper lip filler, and lastly simulated upper lip lift.

Facial feminisation: an overview of the role of the surgeon and orthodontist

Facial feminisation surgery (FFS) aims to feminise the face by changing masculine facial features to feminine ones. It is commonly undertaken for transsexual individuals who are transitioning from male to female or for women who wish to further feminise their facial appearance. Assessment and treatment planning by a multidisciplinary team is essential for any patient considering FFS. Orthodontists have an important role within this team as patients may first present to an orthodontist expressing concerns about the appearance of their jaws. Therefore, it is important that orthodontists have a detailed understanding of FFS procedures, to enable good patient communication, thorough patient assessment and onwards referral where required. This article reviews the common FFS procedures, their indications, and the benefits and risks of each procedure and highlights the role of the orthodontist.

Correction of whistle deformity using autologous free fat grafting: first results of a pilot study and review of the literature

PURPOSE

Whistle deformities are frequent sequelae after surgical correction of cleft lip, trauma, or tumor excision. The aim of this study was to examine the role of autologous free fat grafting in the reconstruction of whistle deformity.

PATIENTS

Fifteen patients with whistle deformity were enrolled in this pilot study. The mean follow-up period was 19 months. Liposuction was done followed by the replantation of an average of 2.2 ml autologous fat per patient (range 0.7-4 ml). An overcorrection was performed in all patients.

RESULTS

All the patients showed improvements in whistle deformity. The mean resorption rate was 53% (range 30-80%). Three patients (20%) were not satisfied with the postoperative result. Six complications were assessed (4× feeling of pressure [27%], one hematoma [7%], one recurrent pain [7%]), but a major complication did not occur.

REVIEW

We also present a review of the literature with different techniques that were described in the last 20 years.

CONCLUSION

Autologous free fat graftings for reconstruction of whistle deformity represent a reliable method with a low complication rate. However, the resorption rate is unpredictable. If necessary, several autologous fat transplantations should be conducted at an interval of at least 6 months.

Autologous dermis - Fat grafts as primary and secondary orbital transplants before rehabilitation with artificial eyes

OBJECTIVE

The aim of this study was to examine the role of autologous dermis-fat grafts in the reconstruction of orbital soft-tissue defects.

PATIENTS

Thirty-six patients (3-84 years) were enrolled in this retrospective study from 2002 to 2014. The dermis-fat graft was primarily transplanted in seven cases, and secondarily in 29 patients. All the patients were evaluated for complications, adequate prosthetic cavity, possibility of artificial eye supply and movement, as well as cosmetic results. Follow-up periods ranged from 25 to 144 months.

RESULTS

All the patients could be supplied with an artificial eye in the long term after dermis-fat transplantation. The clinical evaluation revealed 17 complications allocated to 11 patients. A major complication occurred in three patients (8.3%) so that a surgical correction was necessary. Thirty-three patients (91.7%) showed an aesthetically stable long-term outcome.

CONCLUSION

Dermis-fat grafts for reconstruction of anophthalmic orbit represent a reliable method with a low complication rate and good cosmetic and functional results. The graft can be used as primary and secondary transplants. The stable long-term results and high aesthetic satisfaction lead us to recommend this method as a routine operation.

Surgical correction of upper lip deficit in patients with cleft lip using dermis fat graft

Background:

This study aimed to assess dermis fat graft (DFG) as a choice to correct the tissue deficit in the free border of the upper lip in cleft lip repair surgery.

Materials and Methods:

Thirty-five individuals who referred to Alzahra Hospital at 2013–2014, with lip deformity following the primary repair surgery of cleft lip underwent surgery by DFG technique. Outcomes were assessed 4 months after the surgery based on comparison of preoperative and postoperative photographs.

Results:

The results in 18 (51.42%) patients were excellent, 10 (28.57%) good, and 7 (20%) intermediate according to the satisfaction of patients and investigators in terms of filling of lip deficit and motion of the upper lip. Moreover, complications and pain were minimal after 4-month follow-up.

Conclusion:

This method introduces an admissible method with 80% good to excellent results based on satisfactory of patients and surgeon.

Autologous Breast Augmentation Using Abdominal Dermis Fat Strip Grafts: A Preliminary Report

BACKGROUND

Abdominoplasty and augmentation mastopexy are often performed in the same operation. Although silicone breast implants are usually used for breast augmentation, resected abdominal dermis fat tissue can be used for this purpose. We describe a new autologous breast augmentation technique using dermis fat grafts obtained from a simultaneous abdominoplasty operation.

METHODS

This new technique was used in eight breasts of four patients who requested abdominoplasty and augmentation mastopexy operations in the same session. First, excess abdominal skin was de-epithelized. Dermis fat strips were harvested either in situ or extracorporeally from this area. The prepared strips were then inserted into the pectoralis major muscle during the mastopexy operation.

RESULTS

The patients were followed up for 7 months to 6 years. No infection or other problems regarding the technique were observed. Magnetic resonance imaging obtained from one patient showed graft survival after 2 years. A slight augmentation, presumably 50 to 100 mL, was observed per breast in all of the patients.

CONCLUSION

Dermis fat strips obtained from an abdominoplasty operation can be used to obtain slight augmentation during mastopexy in patients requesting both of these operations in the same session. Validation of this new technique requires more experience with additional patients.

Experimental and Clinical Efficacy of Two Hyaluronic Acid-based Compounds of Different Cross-Linkage and Composition in the Rejuvenation of the Skin

BACKGROUND

In the field of aesthetic medicine there is an increasing demand for safe and effective hyaluronic acid (HA) fillers to counteract the aging process.

METHODS AND AIMS

We designed a study to evaluate the safety and histological biocompatibility of Aliaxin® Global Performance, a cross-linked HA filler and Viscoderm® Skinkò E, a product composed of non-cross-linked HA and a complex including vitamins, antioxidants, amino acids and minerals injected into the skin of guinea pigs. Then, we translated our findings into the clinical setting, administering a combination of these compounds to patients seeking a facial rejuvenation procedure targeting moderate-to-severe wrinkles affecting the nasolabial folds.

RESULTS

The animal study showed that the two compounds did not induce any significant inflammatory reactions and increased collagen and elastic fibers in the skin. In the clinical setting, injection of Aliaxin® Global Performance, followed by Viscoderm® Skinkò E, resulted in a higher improvement in nasolabial fold hydration, trans-epidermal water loss and wrinkle aesthetic appearance, if compared with a protocol based on Aliaxin® Global Performance alone.

CONCLUSION

In summary, we show evidence on the safety and mechanism underlying two new HA-based compounds of different cross-linkage and composition, proposing that they can be safely used in combination in patients seeking facial rejuvenation procedures with long-lasting efficacy.

Five-year Experience with Perma Facial Implant

SUMMARY

Augmentation cheiloplasty is becoming an increasingly popular aesthetic procedure despite current methodologies having met with disappointment among surgeons and patients. The goal of this study was to examine the benefits and drawbacks of 1 device in particular-Perma Facial Implant (PFI). The senior authors (P.R. and S.W.H.) performed 832 consecutive PFI lip augmentations with excellent results based on photographic documentation, patient satisfaction surveys, unbiased surgeon ratings, and low complication rates. In addition to augmenting thin lips, PFIs hide excess dentition and improve vermilion rhytids and pout. Contrary to alternatives, they are both permanent and reversible. However, they do not level out asymmetries or benefit razor-thin lips without prior lifting or mucosal advancement.

The endonasal lip lift: personal technique

Given the shortcomings of current methods to shorten the cutaneous upper lip, the senior authors modified the traditional subnasal lip lift with endonasal flaps, performing 311 such lifts over a 15-year period. Ideal surgical candidates are adults with tall philtra, negligible dental show, and no maxillary abnormalities. Benefits of the procedure include improved scar appearance and pout, absence of tension in visible areas, increased dental and vermilion display, and minimal scar migration (ie, loss of lift). Moreover, caudal rhinoplasty procedures are facilitated via the same incision sites. Undercorrection, sill widening, and alar distortion are mostly avoidable (or at least corrigible) complications. Nasal sill disruption, however, remains an inevitable drawback that may be minimized through meticulous technique.

Augmentation of the upper lip with temporalis fascia: a quantitative analysis

BACKGROUND

Lip augmentation is a very common cosmetic procedure. A wide variety of materials have been used to enhance and contour the lips, including alloplastic and autogenous substances.

OBJECTIVES

The authors describe their experience with augmentation of the upper lip using an autologous graft from the temporalis fascia.

METHODS

Patients were enrolled prospectively. Upper-lip projection and vermilion show were measured preoperatively and 6 months postoperatively for 19 patients who were candidates for lip augmentation with temporalis fascia.

RESULTS

Six months postoperatively, the mean values for upper-lip projection and lip vermilion were significantly greater than preoperative measurements.

CONCLUSIONS

Augmentation of the upper lip with temporalis fascia appears to be safe and effective. Larger patient series, longer follow-up, and comparative studies are needed to corroborate these preliminary results.

Surgical correction of whistle deformity using cross-muscle flap in secondary cleft lip

BACKGROUND

The whistle deformity is one of the common sequelae of secondary cleft lip deformities. Santos reported using a crossed-denuded flap for primary cleft lip repair to prevent a vermilion notching. The authors modified this technique to correct the whistle deformity, calling their version the cross-muscle flap.

METHODS

From May 2005 to January 2011, 14 secondary unilateral cleft lip patients were treated. All suffered from a whistle deformity, which is characterized by the deficiency of the central tubercle, notching in the upper lip, and bulging on the lateral segment. The mean age of the patients was 13.8 years and the mean follow-up period was 21.8 weeks. After elevation from the lateral vermilion and medial tubercle, two muscle flaps were crossed and turned over. The authors measured the three vertical heights and compared the two height ratios before and after surgery for evaluation of the postoperative results.

RESULTS

None of the patients had any notable complications and the whistle deformity was corrected in all cases. The vertical height ratios at the midline on the upper lip and the affected Cupid's bow point were increased (P<0.05). The motion of the upper lip was acceptable.

CONCLUSIONS

A cross muscle flap is simple and it leaves a minimal scar on the lip. We were able to reconstruct the whistle deformity in secondary unilateral cleft lip patients with a single state procedure using a cross-muscle flap.

The no-scar lip-lift: upper lip suspension technique

BACKGROUND

Addressing the long upper lip has been a complex problem for some time. Methods such as the subnasal skin excision and the vermillion advancement technique have been described, but both leave a visible scar. A no-scar lip-lift technique is necessary for a subset of patients who have a long upper lip and will not accept a visible scar.

METHODS

The upper lip is shortened via an intranasal incision and suspension suture that elevates the upper lip and anchors it to the anterior nasal spine. A retrospective review of 92 patients who had undergone upper lip-lift with the no-scar suspension technique was performed. Three plastic surgeons assessed the pre- and postoperative results and determined the presence of improvement in four categories: lip shortening, lip projection, incisor show, and vermillion show.

RESULTS

The lip parameters improved, with 85% of the patients showing noticeable lip shortening, 79% showing increased sagittal projection, 74% exhibiting increased incisor show, and 25% exhibiting increased vermillion show. All the patients had improvement in at least one of the four categories. Complications were experienced by two patients with a suture abscess and one patient with an unraveled suture.

CONCLUSION

The overall lip contours improved after the lip suspension technique, most noticeably in terms of lip height and sagittal projection, and the scar was hidden intranasally.

Complications from injectable materials used for breast augmentation

Fewer surgical procedures have a history as fascinating and as terrifying as breast augmentation. Initial efforts at augmentation involved injection of substances such as paraffin or oil into the breast tissue, or the implantation of substances including ivory or glass balls, or rubber. More recent efforts have included the injection of liquid silicone or polyacrylamide hydrogel. The current paper reviews four distinct eras of breast augmentation, and provides the current status of these injection materials. A case report is presented on a woman whose breasts were injected with polyacrylamide hydrogel in Iran. The current status of this group of materials is also presented. During the past 110 years, history has repeated itself during each of the four eras of injection.

Bilobed mucosal flap for correction of secondary lip deformities following cleft lip surgery

BACKGROUND

Upper lip whistling deformities, asymmetric upper lip thickness and insufficient vermilion tubercle often occur simultaneously in an affected individual. Unfortunately, these deformities cannot be corrected by a single conventional method. Here, we describe a new technique, using a vermilion-bilobed flap, to address the triplex of deformities simultaneously.

METHODS

A total of 30 A Thirty patients were included in this study. Their ages ranged from 10 to 35 years. The flap consisted of two lobes: one lobe of the flap was located at the oral mucosa of the prolabium, which allowed for correction of the whistle deformity as well as augmentation of the vermilion tubercle; the other was located at the vermilion mucosa on the lateral side of the cleft, which effectively repaired oral mucosal defects. Quantitative measurements of the vermilion shape were performed before surgery and 6 months postoperatively.

RESULTS

All patients healed well with no complications of the flaps.The gross appearance of the vermilion was significantly improved. Normal tubercles were restored and symmetric profiles of vermilion were achieved. All the patients were satisfied with their final appearance.

CONCLUSIONS

The bilobed vermilion mucosal flap is a safe technique, easy to perform and effectively corrects the combined secondary deformities associated with cleft lip surgery.

Unacceptable results with an accepted soft tissue filler: polyacrylamide hydrogel

BACKGROUND

Polyacrylamide hydrogel, considered a safe and biocompatible soft tissue filler, is widely used in cosmetic procedures. Its use for facial contouring and breast augmentation in Iran has increased dramatically in recent years. Most patients and many doctors are unaware of possible and reported adverse effects related to its administration.

METHODS

This study enrolled 98 patients experiencing unsatisfactory results and complications of polyacrylamide hydrogel. Adverse effects related to gel administration were documented for all the patients. Lab values were requested together with related medical care and surgical treatments, and gel was extracted by incision, milking, and irrigation.

RESULTS

The most common findings at the time of presentation were inflammation (n = 51), asymmetry (n = 31), irregularity (n = 18), infection and abscess formation (n = 11), and gel migration (n = 8). In one patient, severe anaphylactoid reaction was observed 1 week after gel injection, which led to significant complications for the patient. Histologic findings showed granuloma formation (n = 17), fat necrosis (n = 9), and fibrosis (n = 17). Macroscopic gel-related complications resolved after extraction of the injected material, except for skin necrosis and hyperpigmentation, which remained unchanged. For eight patients, the gel could not be extracted by squeezing and irrigation entirely. Three patients experienced gel reaccumulation after seemingly complete removal of the gel.

CONCLUSIONS

A wide range of complications seen among our patients showed that polyacrylamide hydrogel may not be as safe and biocompatible as it was thought previously. Both patients and physicians must be aware of the potential side effects of polyacrylamide hydrogel before gel administration.

Current applications and safety of autologous fat grafts: a report of the ASPS fat graft task force

TASK FORCE STATEMENT: In 2007, the American Society of Plastic Surgeons formed a task force to conduct an assessment regarding the safety and efficacy of autologous fat grafting, specifically to the breast, and to make recommendations for future research. The task force formulated specific issues regarding fat grafting and then compiled them to focus on five broad-based questions: 1. What are the current and potential applications of fat grafting (specifically breast indications, and if data are available, other cosmetic and reconstructive applications)? 2. What risks and complications are associated with fat grafting? 3. How does technique affect outcomes, including safety and efficacy, of fat grafting? 4. What risk factors need to be considered for patient selection at this level of invasiveness? 5. What advancements in bench research/molecular biology potentially impact current or future methods of fat grafting? To answer these questions, the task force reviewed the scientific literature, critically appraised the information available, and developed evidence-based practice recommendations. Although the primary issue of interest was fat grafting to the breast, other aspects of fat grafting were evaluated.

Upper-lip augmentation by graft of preseptal orbicularis oculi muscle through blepharoplasty

BACKGROUND

Upper-lip augmentation is used to enhance a thin upper lip or correct lip deficiencies or senile hypotrophy. We describe an easy, effective, and reproducible technique.

METHODS

We use two preseptal orbicularis oculi muscle grafts that provide a reliable option for soft-tissue upper-lip augmentation, with improved vertical lip height and lateral lip projection and reappearance of the Cupid's bow. Muscle grafts are harvested from a blepharoplasty done at the same time.

RESULTS

The advantages of this procedure include the creation of an anatomically natural upper lip through preserving the continuity and function of the labial structure, good augmentation, no donor-site morbidity, no visible scars on the vermilion, and successful rejuvenation with the associated blepharoplasty.

CONCLUSION

Both patients and surgeons were satisfied with the results because the muscle grafts produce a youthful appearance by adding natural, soft roundness and fullness to the upper lip without an artificial look or the use of synthetic material, providing long-term augmentation.

Granulomatous foreign-body reaction involving oral and perioral tissues after injection of biomaterials: a series of 7 cases and review of the literature

PURPOSE

Injectable implants used for soft-tissue augmentation may lead to a granulomatous foreign-body reaction. The aim of this report is to present 7 new cases of foreign-body granulomas involving the oral and perioral tissues, after injection of biomaterials to achieve soft-tissue augmentation. In addition, the clinical and epidemiological profile of this condition is summarized, based on a review of the English-language literature of all previously described cases.

PATIENTS AND METHODS

We report on 7 new cases of granulomatous foreign-body reaction involving the oral and perioral tissues after the injection of biomaterials. A comprehensive literature review is also presented.

RESULTS

The literature search revealed 49 cases of this condition affecting the oral and perioral tissues. Our 7 patients were female, with a mean age of 52.8 years (range, 34 to 70 years). The lower lip was affected in 4 cases, 1 case was located in the upper lip, 1 case in the buccal mucosa, while 1 case involved 2 different sites (upper lip and buccal mucosa). Histopathologic examination revealed numerous cells with clear, often multiple, cytoplasmic vacuoles, bearing a resemblance to lipoblasts. Immunohistochemistry revealed diffuse positivity for the histiocytic marker CD68.

CONCLUSIONS

The diagnosis of granulomatous foreign-body reactions may be challenging because of their microscopic resemblance to liposarcoma, and because of the occasional reluctance of patients to report the previously performed esthetic procedure. A clinical history, histopathologic examination, and immunohistochemical analysis (as needed) are essential in achieving an accurate diagnosis.

Rabbit Ear Cartilage Regeneration With a Small Intestinal Submucosa Graft

OBJECTIVES/HYPOTHESIS

The objective was to demonstrate that interpositional grafting with porcine small intestinal submucosa promotes cartilage regeneration following excision of rabbit auricular cartilage.

STUDY DESIGN

Blinded, controlled study.

METHODS

Eight New Zealand white rabbits underwent excision of auricular cartilage on two sites with and two sites without preservation of perichondrium. Porcine small intestinal submucosa was implanted into one site with and one site without intact perichondrium. Remaining sites served as control sites. Histological assessment was performed at 3 (n = 4) and 6 (n = 3) months and at 1 year (n = 1) after grafting.

RESULTS

Histological evaluation showed cartilage regeneration accompanied by chronic inflammation in areas in which porcine small intestinal submucosa was implanted between layers of intact perichondrium. Other sites failed to show significant cartilage regeneration.

CONCLUSION

The results of the study using porcine small intestinal submucosa as a bioscaffold for cartilage regeneration are promising and justify further animal and human studies.

Simultaneous harvesting of cancellous iliac bone for alveolar cleft closure and dermis for augmentation of median tubercle

Children with repaired cleft lip/palate require secondary closure of the alveolar cleft and, often, nasolabial revision. We describe a technique performed in 61 patients for harvesting bone for the alveolar defect and dermis for augmentation of the median tubercle, taking both from the posterior iliac region. The advantages of the posterior approach are as follows: (1) the same donor site is used for cancellous bone and dermal graft and (2) the child's appearance is improved along with alveolar cleft grafting.

Biocompatibility of Agarose Gel as a Dermal Filler: Histologic Evaluation of Subcutaneous Implants

BACKGROUND

The search for safe and effective tissue fillers has been an ongoing effort in plastic and cosmetic surgery over recent decades. Biocompatibility is a prerequisite for any substance to be used as an implant material, and potential biomaterials need to be characterized by histologic evaluation of tissue responses. Collagen is a well-known tissue filler. Agarose gel is widely used in bioengineering. Both products are considered biocompatible. The purpose of this study was to evaluate the bioactivity of agarose gel as a dermal filler compared with collagen.

METHODS

Tissue responses to agarose gel and collagen were evaluated in a rat in vivo model (n = 96). Four groups were evaluated: group 1 (n = 24), rats with agarose gel implants; group 2 (n = 24), rats with collagen implants; group 3, a placebo group (n = 24); and group 4, a control group (n = 24). Responses and biocompatibility were assessed by histopathologic and histomorphometric evaluation at 1 week to 8 months after implantation.

RESULTS

Agarose gel showed marked bioactivity and biodegradation, although the implants integrated well into tissues: newly formed collagen bands were observed inside the implants and no granulomas were detected. Collagen implants showed low cell infiltration and a significant loss of product over time.

CONCLUSIONS

Agarose gel is a biocompatible product that can be considered for use as a tissue filler. Further investigation is required to assess its long-term efficacy and safety.

The use of polyacrylamide gel in soft-tissue augmentation: an experimental assessment

BACKGROUND

An increasing number of soft-tissue filler substances that lack experimental and clinical data have been introduced into plastic surgery practice outside the United States. One of these substances is polyacrylamide gel. It contains 2.5% polyacrylamide and 97.5% water. It is homogenous and stable, and has optimum viscosity and elasticity.

METHODS

One milliliter of polyacrylamide gel was injected into the subcutaneous layer of the right ear in 28 rabbits. The rabbits were divided into two groups, according to when the material was harvested and evaluated. Material was harvested at 4 months in 15 rabbits and 7 months in 13 rabbits. Each group underwent volumetric ultrasound evaluation, magnetic resonance imaging, and histological evaluation with hematoxylin and eosin and CD68 staining.

RESULTS

Results were easily observed because of the superficial position of the injected material. There were no systemic or local complications. The samples harvested showed a clear and jelly-like consistency similar to that of the initially injected material. The volume was constant after 6 weeks, after an initial period of acute stretching. Ultrasound volumetric analysis was also constant in all groups. At 7 months, a stable volume of 1.0 +/- 0.2 ml was observed. Magnetic resonance imaging scanning showed that the material was stable and that there was no inflammatory reaction. Histological analysis revealed a minimal foreign-body reaction, and the injected material was occasionally surrounded by a thin collagen membrane. The material remained in place.

CONCLUSIONS

Polyacrylamide gel has a long-lasting effect, with minimal volume variation. It remains soft to the touch and in place.

Long-Lasting and Permanent Fillers: Biomaterial Influence over Host Tissue Response

BACKGROUND

The purpose of this study was to attempt to understand why some injectable fillers produce frequent ill effects and some do not, by reviewing the available agents and analyzing them through the knowledge of biomaterial studies, which show clearly what type of reactions can be expected according to the chemical used.

METHODS

A study of long-lasting and permanent fillers was performed in an attempt to understand the specific reactions induced by each agent. Agents were then compared with manufacturers' allegations and published data on complications.

RESULTS

All the available products have a potential for complications. However, the difference between the normal healing process and true inflammatory granuloma must be established. For a volume effect, the implant, although deep, should induce the smallest inflammatory reaction, to avoid any long-term side effects. Particulate implants with porous or irregular surfaces are potentially more reactive than spherical, smooth-surface particles. Gels and oils have a potential for fragmentation, and each droplet will start a new inflammatory phase. For a superficial treatment, is seems better to use a "passive" filler, which should have no inflammatory reaction. The problem remains for combined indications: volume and smoothing, deep and superficial. After hyaluronic acid injections in areas previously treated with a nonresorbable agent, severe inflammatory granulomas have appeared, and it is not possible to state whether they are attributable to the new product, even a resorbable one, or to reactivation of the sleeping reaction from the previous implant.

CONCLUSION

There is an obvious need for serious, precise, and objective studies on most of the available fillers, which have not been properly scientifically studied on human skin.
