RESUMEN
Although the cancellation of elective procedures due to the COVID-19 outbreak has been a vital precaution, it has resulted in the suspension of aesthetic procedures and surgeries worldwide. Consequently, this postponement and other factors might have a negative impact on patients planning to undergo aesthetic procedures. Understanding the changes in patient motivation and perception in comparison to the prepandemic period is imperative for proper adjustment of plastic surgery clinics.A prospective questionnaire study was conducted on patients with cancelled aesthetic surgeries or procedures to determine the effects that coronavirus disease 2019 (COVID-19) had on patient motivation regarding cosmetic surgery and procedures and to establish a relationship between patient characteristics and the overall effect of pandemia on the perception of cosmetic surgery.Although most patients felt angry or frustrated due to the cancellation of their surgeries or procedures, the majority accepted that it was a necessary precaution. Patients with a history of previous minimally invasive procedures had a significantly higher ratio of acceptance for cancellations, whereas single patients were more likely to want to have their treatments done if the decision were left up to them. A subset of patients considered undergoing additional cosmetic procedures in the setting of self-isolation, and all patients stated that they would reschedule once the pandemia was under control.Patients with established motivation for plastic surgery and minimally invasive procedures ultimately plan to resume their normal treatments alongside others after the pandemia subsides. Plastic surgeons must actively communicate with their patient population during this time to properly educate, embrace, and direct them under scientific guidelines.

BACKGROUND: Treatment of a sunken appearance of the temporal region using injectable fillers is a popular procedure. The temporal fossa has very complex anatomy due to multiple vessels running in the different tissue layers. A severe complication in the form of non-thrombotic pulmonary embolism (NTPE) can occur as a result of an inadvertent injection in the middle temporal vein (MTV) while performing temporal fossa filler procedures. Therefore, in-depth knowledge and understanding of the MTV anatomy are essential for successful and safer injectable procedures of the temporal fossa. OBJECTIVES: While there have been many studies to describe the arteries in this region, there is limited information about the location and course of the middle temporal vein. This literature review is aimed at providing detailed information about the course, depth, and size of the MTV to help aesthetic practitioners in performing safer temporal fossa filler injections. This information is imperative to delineate the 'venous danger zone' in the temple region. METHODS: The preferred reporting items for systematic reviews and meta-analyses guidelines were used for this review. A literature search was performed to find the articles providing details about the MTV anatomy and the measurements related to its course and size. RESULTS: A review of the literature showed that the MTV displays a consistent course and depth in the temporal region, with high variability in its diameter. The middle temporal vein width varied between 0.5 and 9.1 mm in various studies. The middle temporal vein receives many subfascial tributaries from the surface of the temporalis muscle, and for most of its course runs in the fat pad enclosed between superficial and deep layers of the deep temporal fascia. A 'venous danger zone,' in the interfascial planes of the temporal fossa, which contain the main part of the MTV and its tributaries, has been proposed in this paper. CONCLUSIONS: The temporal fossa filler procedures need great caution, and knowledge of the depth and course of the MTV is essential for avoiding NTPE.

BACKGROUND: Although columellar strut grafts (CSGs) are considered among the fundamental steps for providing nasal tip support, a downward rotation of the nasal tip in patients with strut grafts can still be encountered. Patient-related factors such as nasal skin thickness can allow the plastic surgeon to anticipate certain drawbacks that can be encountered in the healing phase, but patient-based differences of nasal cartilage and the resulting impact have yet to be investigated. The purpose of this study was to evaluate the effect of the biomechanical properties of CSGs on late postoperative nasal tip position and support. METHODS: The study was undertaken with the participation of 20 patients undergoing closed-technique primary rhinoplasty with CSGs. Each cartilage specimen was biomechanically analyzed to calculate the modulus of elasticity. Preoperative and postoperative images were obtained to determine nasal tip position and rotation with quantitative measurements. Postoperative 3- and 12-month measurements were evaluated according to their relationship with the elasticity modulus of the utilized cartilages. RESULTS: The evaluation demonstrated that the elasticity modulus can impact the long-term support of the nasolabial angle in which an increase in the coefficient of elasticity can result in a decrease in long-term nasal tip support. CONCLUSION: The results of the study reveal a new objective variable that can impact nasal tip dynamics and patient-related differences following rhinoplasty. This study not only brings forth a different perspective in the evaluation of nasal tip dynamics but can also provide data for determining ideal values for cartilage prefabrication.

BACKGROUND: Although the excision of the buccal fat pad has become very popular for achieving a slimmer midface, not all patients are good candidates for this procedure. Unfortunately, studies that provide guidelines by emphasizing volumetric and technical details are limited. OBJECTIVES: The study compared preoperative and postoperative volumetric data to identify the amount of tissue that can safely be removed and important technical concepts involved in lower cheek contouring with buccal fat pad excision. METHODS: Patients complaining of cheek fullness were evaluated to determine if they were good candidates for the procedure. Eligible patients were screened with transbuccal ultrasound to determine tissue volumes and anatomical details. Intraoperative and postoperative, 6th-month volume measurements were undertaken and residual tissues and vascular pedicles reevaluated. RESULTS: Ultrasound imaging showed that the mean preoperative volume of the fat pads was 11.67 ± 1.44 mL, and the mean postoperative volume was 8.58 ± 1.07 mL. The mean volume of the excised tissues was 2.74 ± 0.69 mL. Postoperative buccal fat pad volume values correlated with the reported average in the literature for the same age group. CONCLUSIONS: Buccal fat pad removal is an effective technique for refining the facial silhouette that should be reserved for patients with increased buccal fat pad volume. Removal of only the excessive portion of the fat pad is important because this structure provides significant volume in the midface that can be difficult to restore once aging affects the surrounding soft and bony tissue.

Background: Lip augmentation procedures have increased drastically in the last years as patients seek to enhance the shape and size of their lips with dermal fillers. One of the main concerns faced with these procedures is the pain inflicted through injections. On the other hand, many different techniques have been introduced for the reduction of pain while performing office-based minimal invasive procedures. Objectives: This study aims to determine the analgesic effect of vibration anesthesia during lip augmentation procedures and to evaluate its overall effect on the comfort of patients. Methods: A split-lip study was designed in a randomized fashion for 25 lip augmentation patients who received hyaluronic acid fillers with or without with a concurrent vibration stimulus on either half of their lips. Patients were asked to score the pain that they felt during lip injections on a scale from 0 to 10 (0 being no pain and 10 being the worst pain ever felt) for either lip half. The pain scores were then analyzed for significance. Results: The overall pain score on the vibration-assisted side was 3.82 ± 1.73 while the pain score for the side with no vibration was 5.6 ± 1.76 (P < 0.001). Twenty-three patients (92%) felt less pain with the addition of vibration while, interestingly, 2 patients (8%) stated that they felt an increase in pain levels on the vibration-treated side. Conclusions: Vibration devices can be a safe and effective tool for lowering pain levels in patients undergoing lip augmentation with hyaluronic acid fillers. Level of Evidence: 2.

INTRODUCTION: Reconstruction of cranial bone defects is one of the most challenging problems in reconstructive surgery. The timing of reconstruction, the location of the defect, the materials to be used, and the medical history of the patient are parameters that have been mostly discussed in the literature. To the best of our knowledge, there has not been any published classification for the cranial bone defect reconstruction according to defect size. MATERIALS AND METHODS: Twelve patients underwent reconstruction of cranial vault defects. Cranial bone defects were classified into 3 groups according to the size of the defect. The small-sized group included the defects smaller than 25 cm(2), the medium-sized group included the defects between 25 to 200 cm(2), and the large-sized group included the defects larger than 200 cm(2). The small-sized defects were reconstructed with split calvarial graft, demineralized bone matrix, or hydroxyapatite cement; the medium-sized defects were reconstructed with split calvarial graft or allogenic bone graft; and the large-sized defects were reconstructed with methyl methacrylate, autoclaved bone, or porous polyethylene. RESULTS: Two patients needed revision for irregularities with demineralized bone matrix. Other patients had no skull defects or irregularities for which revision was suggested. CONCLUSIONS: We believe that the size of the defect is important for the reconstruction of cranial vault defects and that using a standard algorithm can increase the success rate.

INTRODUCTION: Botulinum toxin type A (BTX-A) is currently used in temporal brow lifting. Reducing the activity of the superolateral portion of orbicularis oculi muscle causes lateral brow elevation. The objective of this study was to determine the quantitative brow elevation after paralysis of the superolateral portion of orbicularis oculi muscle. MATERIAL AND METHODS: This study includes 10 female patients. Six units of BTX-A were injected into the superolateral portion of the orbicularis oculi in a serial manner into 3 points, below the lateral half of the brow at each side. Bilateral measurements were obtained by using calipers, immediately before and 2 weeks after the treatment. The medial canthus to the medial brow margin (AB), the lateral brow margin to the lateral canthus (CD), the medial brow margin to the lateral brow margin (BC), the brow apex to upper lid margin at the level of the lateral limbus (EF), the brow apex to the medial brow margin (EB), the brow apex to the lateral brow margin (EC), and upper eyelid margin to lower eyelid margin at the level of the pupil (GH), were measured. RESULTS: There were no statistically significant differences found between pretreatment and posttreatment left and right measurements. There were statistically significant increases in CD, EF, and GH measurements, which are point out brow elevation. There were no statistically significant differences found in other measurements. CONCLUSIONS: Same doses of BTX-A application did not disrupt symmetry. Applications of 6U BTX-A to the superolateral portion of orbicularis oculi provide brow elevation and increased interpalbebral distance and upper eyelid distance. Our study has confirmed that BTX-A treatment of superolateral portion of the orbicularis oculi muscle produces quantitative temporal brow elevation.

BACKGROUND: Hormonal changes that take place during the menstrual cycle may have an effect on perioperative bleeding. Previous studies have confirmed a relationship between the menstrual cycle and surgical bleeding in rhinoplasty and breast reduction surgery; yet both surgical sites display changes in accordance with sex hormone levels during the menstrual phase. AIM: The aim of this study was to determine the effect of the menstrual cycle on perioperative bleeding when undergoing surgeries of sites not directly related to menstrual hormonal changes. MATERIALS AND METHODS: Forty-one patients undergoing abdominoplasty were grouped as group A - perimenstrual (0-7, 21-28 days), group B - periovulatory (8-20 days) and group C - postmenopausal. Intra-operative blood loss was calculated during surgery while postoperative blood loss was determined by measuring the amount of drainage. All menstrual data were recorded. Age, body mass index and weight of the resected tissue were also considered as factors that can affect the amount of bleeding and therefore were also evaluated in terms of significance. RESULTS: There was no significant difference between groups regarding intra-operative and postoperative blood loss. Body mass index and weight of the resected tissue had a strong influence on the time of drain removal and the amount of intra-operative and postoperative blood loss. CONCLUSION: This study strongly suggests that the menstrual period does not affect perioperative blood loss for operations on areas less sensitive to sex hormone levels such as the abdomen. In light of the results, we can conclude that the patient's menstrual date is not of vital importance regarding perioperative blood loss when planning surgery for areas with less sensitivity to menstrual hormonal changes.

The experiment was designed to compare the effect of intraoperative platelet-rich plasma (PRP) and fibrin glue application on skin flap survival. In this study, bilateral epigastric flaps were elevated in 24 rats. The right-side flaps were used as the control of the left-side flaps. Platelet-rich plasma, fibrin glue, and thrombin had been applied under the flap sites in groups 1, 2, and 3, respectively. Five days later, all flap pedicles were ligated. Necrotic area measurements, microangiography, and histologic and immunohistochemical evaluations were performed to compare the groups. Platelet-rich plasma reduced necrotic area percentages as compared with other groups. Histologically and microangiographically increased number of arterioles were observed in PRP groups. Thrombin when used alone increased flap necrosis. Vascular endothelial growth factor, platelet-derived growth factor, and transforming growth factor ß3 primary antibody staining showed increased neovascularization and reepithelialization in all PRP-applied flaps. This study demonstrated that PRP, when applied intraoperatively under the skin flap, may enhance flap survival. Thrombin used alone was found to be unsuitable in flap surgery.

BACKGROUND: The aim of this study was to compare the effects of preoperative subcutaneous platelet-rich plasma and fibrin glue administration on skin flap survival. METHODS: One week before surgery; saline, platelet-rich plasma, fibrin glue, and thrombin solutions were applied under rat skin flap areas in Groups I, II, III, and IV, respectively. Unipedicled epigastric flaps were elevated in the first three groups but could not be elevated in Group IV because of preoperative abdominal skin necrosis. Necrotic area measurements, microangiography, and histological and immunohistochemical evaluations were performed. RESULTS: Platelet-rich plasma reduced the percentage of necrotic area when compared to other groups. Histologically and microangiographically an increased number of arterioles were observed in the platelet-rich plasma group. Thrombin (when used alone) caused abdominal skin necrosis. Increased expression of VEGF and PDGF was found in all platelet-rich plasma-treated flaps. There was no significant difference between groups with respect to TGF-ß3 staining intensity. CONCLUSION: In this study preoperative administration of platelet-rich plasma mimicked the pharmacological delay effect and enhanced flap survival. Individual use of thrombin was found to be unsuitable in flap surgery. LEVEL OF EVIDENCE I: This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Bilateral coronal synostosis (brachycephaly) is the most common single-suture synostosis that may lead to functional deficits such as mental retardation. This increases the importance of volume gain during surgery. This study was designed to understand the differences in volume gain, cranial index (CI), and aesthetic outcomes when additional osteotomies or rotations are applied on the frontoparietal segment. METHODS: Acrylic brachycephaly models were prepared. Frontoparietal osteotomy was standard in all models. Frontoparietal segment was fixed: to the same position in surgical control model, after 1.2-cm advancement in advancement model, after 180-degree rotation without advancement in rotation model, after 180-degree rotation plus a horizontal osteotomy and 1.2-cm advancement in rotation plus angled advancement model, and after a horizontal osteotomy without rotation and 1.2-cm advancement and in angled advancement model. RESULTS: Intracranial volume changes (in milliliters) and CIs were as follows between groups: control group, 828/94.1; surgical control group, 830/93.8; advancement model, 900/84.5; rotation model, 834/89.1; rotation plus angled advancement model, 897/82.7; angled advancement model, 902/81.8. CONCLUSIONS: Advancement of the frontoparietal segment is the keystone of surgery in brachycephaly treatment. Making an additional horizontal osteotomy can angle this segment and may supply additional volume gain. Rotation of the frontoparietal segment does not provide additional volume or CI gain but increase better aesthetic outcomes.

BACKGROUND: Facial aesthetic treatments are among the most popular cosmetic procedures worldwide, but the factors that motivate women to change their facial appearance are not fully understood. OBJECTIVES: The authors examine the relationships among the facial areas on which women focus most as they age, women's general self-perception, and the effect of their personal focus on "beauty points" on their perception of other women's faces. METHODS: In this prospective study, 200 women who presented to a cosmetic surgery outpatient clinic for consultation between December 2009 and February 2010 completed a questionnaire. The 200 participants were grouped by age: 20-29 years, 30-39, 40-49, and 50 or older (50 women in each group). They were asked which part of their face they focus on most when looking in the mirror, which part they notice most in other women (of different age groups), what they like/dislike most about their own face, and whether they wished to change any facial feature. RESULTS: A positive correlation was found between women's focal points and the areas they dislike or desire to change. Younger women focused mainly on their nose and skin, while older women focused on their periorbital area and jawline. Women focus on their personal focal points when looking at other women in their 20s and 30s, but not when looking at older women. CONCLUSIONS: Women presenting for cosmetic surgery consultation focus on the areas that they dislike most, which leads to a desire to change those features. The plastic surgeon must fully understand patients' expectations to select appropriate candidates and maximize satisfaction with the outcomes.

OBJECTIVE: The aim of this study was to identify and quantify nasal profile changes following maxillary advancement (MA) and maxillary advancement with impaction (MAI) with Le Fort I osteotomies. METHODS: The study consisted of preoperative and postoperative lateral cephalograms of 42 class III adult patients. The study sample was divided into 2 groups, with the first group composed of 22 patients who underwent MA surgery and the second group composed of 20 patients who underwent MAI surgery. In total, 7 skeletal parameters and 17 soft-tissue parameters related to nasal projection, hump, dorsal convexity, and the nasolabial region were evaluated on the cephalograms, and hard- and soft-tissue relationships were assessed. RESULTS: Nasal length, hump, nasal depths, distance from the most convex point of the Alar curvature to the most inferior point of the nostril, alar curvature-subnasale, and subnasale-pronasale measurements decreased postoperatively. In the MAI group, MA correlated with significant decreases in nasal length and hump. In the MA group, MA correlated with pronasale position (P < 0.05); significant decreases in nasal depth, columella convexity, and subnasale-pronasale length; and significant changes in subnasale position. CONCLUSIONS: There is little difference in the effects of the 2 different maxillary surgeries on the postoperative nasal profile.

PURPOSE: The aim of this study was to emphasize the importance of preoperative surgical planning using 3D skull models in craniosynostosis surgery. METHODS: By using 3D polymethyl methacrylate skull models manufactured using 3D tomography images, the authors previously showed that after fronto-parietal osteotomy, instead of fixing the fronto-parietal bone flap without rotation, angled advancement with horizontal osteotomy provides maximum increase in intracranial volume, in a bilateral coronal craniosynostosis model. After changing the operation technique using data gathered from previous studies, we reviewed two bilateral craniosynostosis patients operated with the new technique and compared it with two patients that were operated with the old technique. RESULTS: Comparing cranial indexes (CI), significant improvement was detected in both groups. The decrease in CI in the second group was slightly better than the first group. In the comparison of intracranial volume (ICV), there was an increase in ICV values in both groups. The percentage of increase between two groups was similar. The morphological outcome was satisfactory in all patients. There were no major or minor complications and morbidity. CONCLUSIONS: Current multislice tomography technology and stereolithographic procedures provide an excellent surgical simulation model to find new techniques and predict the outcome. These models should be used in all complex and syndromic craniosynostosis for both better results and reducing the operative time and associated blood loss.

Despite the insufficient number of experimental studies, platelet-rich plasma (PRP) including high amounts of growth factors is introduced to clinical use rapidly. The aim of this study was to compare the effects of PRP and platelet-poor plasma (PPP) on healing of critical-size bone defects.Bilateral full-thickness, critical-size bone defects were created in the parietal bones of 32 rabbits, which had been studied in 4 groups. Saline, thrombin solution, PPP, and PRP were applied to the created defects before closure. Radiologic defect area measurement results at 0, 4, and 16 weeks were compared between the groups. In addition, densities of the newly formed bones at 16th week were studied. Histologic parameters (primary and secondary bone trabecula, neovascularization, and bone marrow and connective tissue formation) were compared between 4- and 16-week groups.More rapid decrease in defect size was observed in groups 3 and 4 than in groups 1 and 2, both in the 4th and 16th weeks. Newly formed bone densities were also found to be higher in these 2 groups. New bone formation was detected to be more rapid considering histologic parameters, in groups 3 and 4 at 4th and 16th weeks.Study demonstrates that PRP and PPP might have favorable effects on bone healing. Although we cannot reveal any statistical difference between these 2 substances considering osteoinductive potential, PRP group has demonstrated superior results compared with fibrin glue group. Higher platelet concentrations may expose beneficial effects of PRP.

Prominent ear deformity is a common congenital ear deformity. Prominent ear deformity includes components such as valgus of concha, failure of scaphal folding, conchal hypertrophy, and prominent lobule. The deformity and the elastic properties of the ear cartilage determine the method of surgical correction in each case. Concha-mastoid suture, conchal excision, and posterior auricular muscle excision are different treatment options for mild to severe cases of conchal hypertrophy and valgus deformity. In this article we present a method of conchal excision, combined with a posterior auricular muscle flap, to repair severe conchal hypertrophy or valgus deformity. Six patients (11 ears) were operated on using this method. The results obtained were satisfactory. Postoperative results at 6 months were satisfactory in all patients. The smoothness and the natural appearance of the conchal bowls were notable in all patients. In contrast to the early methods of utilizing the posterior auricular muscle by transposing to the scapha or excising, its usage as a muscle flap for conchal hypertrophy and valgus deformity may be a promising option for the future.
