RESUMO
BACKGROUND: Early relapse is an adverse outcome of facelift surgery. The rate of early relapse is an indirect measure of the longevity and efficacy of facelift techniques. However, early relapse after facelift is ill-defined, under-evaluated, and under-reported, and literature data on the subject are dispersed. In this systematic review, we aimed to analyze facelift studies using relapse-related outcomes (RROs). Our secondary aim was to highlight the importance of early relapse as an essential outcome measure. METHODS: The study design was a systematic review of the English literature and meta-analysis of RROs after facelift surgery. RROs that occurred within the first 2 years after surgery were considered "early". Performance, analysis, and reporting were performed in accordance with the PRISMA guidelines. The systematic search was conducted using the PubMed database as of February 2020. Initial screening was performed using the keywords "facelift", "rhytidectomy", "surgical rejuvenation", "face lift", "rhytidoplasty", and "facial rejuvenation". Articles were excluded by using a set of inclusion and exclusion criteria. RESULTS: RROs were reported only in 4.4% (19/433) of the papers that underwent full-text review. The frequency of RROs ranged between 0.2 and 50% among facelift papers. The weighted median rate of RROs after facelift surgery was found to be 2.4% in the meta-analysis. CONCLUSIONS: Future research on preventive measures will be successful upon acknowledgment of the actual prevalence of this problem. Consensus on its definition and objective criteria for its diagnosis are required for further progress.

BACKGROUND: Subperiosteal midface lift provides a comprehensive solution to the soft tissue component of midfacial aging. However, midfacial aging also has a skeletal component that is rarely addressed with conventional mid-facelift techniques. Moreover, many of the adverse outcomes after a mid-facelift are closely related to failures and limitations of mid-face fixation. The author's technique was designed to overcome these limitations. OBJECTIVES: The author aimed to describe the rationale, technical details, and outcomes of the author's mid-facelift technique with intraorbital fixation. METHODS: This study was a retrospective review of 82 nonconsecutive cases where the intraorbital fixation mid-facelift was performed by the author between September 2016 and December 2021. Patient data were obtained from patient records and standardized photography. Preoperative differences in mid-face volume were assessed utilizing the Allergan midface volume deficit scale on standardized photography. RESULTS: The average mid-face volume deficit score significantly improved after surgery. Failure of fixation, flat midface deformity, and relapse of mid-face ptosis were not seen in any of the primary patients. Infraorbital hollow did not recur in any of the patients operated on with this technique. None of the primary patients (0/58) in this series developed ectropion or permanent lower eyelid malposition. CONCLUSIONS: Intraorbital fixation mid-face lift is an effective and durable surgical option for the treatment of midfacial aging. The technique is applicable in problem cases such as negative vector patients, negative canthal tilt patients, male patients with large bags, and secondary lower blepharoplasties where conventional techniques tend to fail.

BACKGROUND: Retaining ligaments must be fully released for effective soft-tissue mobilization during sub-superficial musculoaponeurotic system (SMAS) facelifts. Standard deep temporal fascia and lateral SMAS fixation techniques may fail earlier than anticipated, which may cause a relapse of facial aging signs. Reconstruction of retaining ligaments was previously proposed to enhance facelift fixation. OBJECTIVES: The author sought to assess the effect of their ligament reconstruction technique on early relapse rates and complication rates. METHODS: This study was a comparative analysis of 188 consecutive facelift cases where retaining ligaments were reconstructed employing the described techniques. A total 104 patients with standard fixation were analyzed in the control group. A novel set of criteria was established for the diagnosis of early relapse after facelift surgery based on the validated Merz scale. RESULTS: Early relapse rate was significantly lower (0.53% vs 5.76%) in the ligament reconstruction group compared with the control group. Ligament reconstruction was associated with an increased rate of temporary nerve paralysis (8.5%). CONCLUSIONS: Sub-SMAS reconstruction of retaining ligaments enhances facelift fixation and reduces the rate of early relapse. Increased risk of temporary neuropraxia is a reasonable trade-off.

BACKGROUND: The posterior auricular nerve (PAN) is an inspiring candidate for the additional axonal source in long-term facial paralysis to improve the functional results of the cross-facial nerve (FN) graft technique. However, no studies have analyzed the PAN's axonal load and its microscopic anatomy to assess its utilization in facial reanimation. The present study aims to examine the anatomical and microscopic features of the PAN to analyze its feasibility as a donor nerve. METHODS: The bilateral facial side of 14 fresh frozen adult human cadavers was examined for the study. The PAN's anatomical course was recorded, and nerve specimens from the PAN and zygomatic nerve (ZN) were obtained to compare their microscopic anatomy and axon counts using a light microscope and transmission electron microscope. RESULTS: The PAN's average branching distance and its course length were 5.8 ± 2.69 mm and 59.2 ± 5.85, respectively. The mean number of myelinated axons was 600.28 ± 69.97 in the PAN and 728.85 ± 166.31 in the ZN. This difference between the two nerves was statistically significant (p = 0.002). However, considering the gender variable, the mean axon counts of PAN and ZN were statistically similar for face sides and their average. Furthermore, the ultrastructural anatomy of both nerves was similar in electron microscopic evaluation. CONCLUSIONS: The present study confirms that the PAN is a proper candidate to be a supportive donor nerve due to its isolated site, consistent anatomical course, convenient ultrastructural anatomy as well as axonal load.

BACKGROUND: Reduction rhinoplasties, regardless of the methods used (structural or preservation), can cause a reduction in the internal nasal volume, which may lead to breathing problems. In 1977, Webster proposed preserving a little triangle in the beginning of the lower lateral osteotomy line to prevent breathing problem. However, its importance is still controversial. OBJECTIVES: and methods: This prospective randomized controlled study (level of evidence 1) included 46 patients without nasal breathing problem. High-to-low (Webster's triangle preservation) osteotomy (control group, n = 23) and low-to-low osteotomy (study group, n = 23) were performed. All operations were performed according to the proposed volumetric rhinoplasty steps (examination/measurement, prevention and treatment). Nasal obstruction symptom evaluation (NOSE) test, visual analog scale, acoustic rhinometry, rhinomanometry, peak nasal inspiratory flow (PNIF), and three-dimensional measurements were performed in all patients. Breathing tests were repeated before and 6 months after surgery with and without xylometazoline administration. RESULTS: No statistically significant difference in NOSE and visual analog scale scores was found between the two groups. Acoustic rhinometry, PNIF, and rhinomanometry findings showed no statistically significant breathing difference between the two groups. CONCLUSIONS: In reduction rhinoplasties, a decrease in the internal volume may be expected as directly proportional with the reduction amount. The decrease in the internal volume may create nasal breathing problems. To prevent it, nasal airflow should be adjusted according to new anatomy. In this study, we discussed "volumetric rhinoplasty" steps to prevent breathing problems in reduction rhinoplasty. Following these steps, not preserving Webster's triangle (low-to-low osteotomy) has no effect on the nasal airway.

BACKGROUND: The posterior cephalic soft triangle is formed between the posterior cephalic border of the lower lateral cartilage, posterior caudal border of the upper lateral cartilage, and the caudal edge of the nasal bone. PCST is an important component of the external nasal valve which provides resistance against dynamic collapse. OBJECTIVES: The objective of this study was to describe the anatomy of the PCST and to demonstrate its anatomic variations, dynamic interplays, and surgical implications. METHODS: A retrospective review was conducted of 310 primary and 42 secondary cases who underwent extended open approach rhinoplasty by the first author. The structures that create the PCST of the nose were preserved unless resection/displacement of them was absolutely necessary. Whenever an external nasal valve pathology was found, it was corrected with one or combination of the following maneuvers: triangular PCST onlay graft, caudal bone outfracture, alar rim graft, lateral crural strut graft. RESULTS: Twenty-four non-consecutive cases were identified in which PCST was intraoperatively confirmed to be weak or deformed. The most common pathology in the PCST was overresection of the posterior segments of the LLC during primary surgery (54.1%), followed by en bloc medialization of the PCST (33.3%). Triangular onlay grafting of the PCST was the most common corrective surgical intervention (83.3%), followed by corrective lateralization of caudal edge of nasal bone (29.1%). External valve function has been restored in 21 (87.5%) cases. CONCLUSIONS: PCST of the nose is an important anatomic landmark which has esthetic and functional significance in rhinoplasty.

BACKGROUND: Our aim was to create a new rodent hind limb lymphedema model lacking the fibrosis effect induced by radiotherapy and subjected to the inhibition of lymphangiogenesis via sirolimus (rapamycin) to maintain a chronic lymphedema model and investigate its reliability for human treatment modalities. METHODS: Forty-two Sprague-Dawley rats were randomly assigned to 7 groups: (1) surgery control, (2) vehicle-surgery control, (3) vehicle control, (4) rapamycin control, (5) surgery with 1 mg/kg per day rapamycin, (6) surgery with 1.5 mg/kg per day rapamycin, and (7) surgery with 2 mg/kg per day rapamycin. All surgeries were performed on the right hind limbs, with the left hind limbs also considered as a control. The drug and its solvent were administered daily into the relevant groups intraperiteonally. The presence of lymphedema was investigated by weekly limb circumference measurements, microcomputed tomography, fluorescence lymphography using indocyanine green dye, and microscopic evaluation at the end of the sixth week to determine any histological changes in the hind limbs. RESULTS: In group 1, lymphedema was observed for 2 weeks (P = 0.032), whereas in groups 5, 6, and 7, lymphedema lasted for 3 weeks (P < 0.05.) Fluorescence using indocyanine green revealed that the edema was totally resolved after 6 weeks of surgery by a well-developed superficial lymphatic organization instead of the normal distinct vessel structure. Histologically, groups 1, 5, 5, and 7 demonstrated a significant increase in both the number of macrophages (P < 0.001) and newly formed lymphatic vessels in the right side surgically treated hind limb (P < 0.05). CONCLUSIONS: Despite the extreme surgical destruction and lymphangiogenesis inhibition in the rat model, the sustained lymphedema did not last >3 weeks. Because of the rapid neolymphangiogenesis in murines and a different wound healing mechanism, they should not be considered as an appropriate model for research on human lymphedema in first place.

PURPOSE: Although the Oberg-Manske-Tonkin (OMT) classification has been recommended by the International Federation of Societies for Surgery of the Hand owing to some insufficiencies of the Swanson classification system, it has not achieved a universal adoption by hand surgeons. In this study, we hypothesize that the OMT classification can be used easily to classify congenital upper extremity anomalies. We also aim to make epidemiological analysis of congenital upper extremity anomalies with the OMT classification and to compare the applicability of the OMT and the Swanson classifications. METHODS: We retrospectively analyzed 711 patients and 833 extremities operated on between 2012 and 2017. Photographs, plain x-rays, and brief medical histories of the patients were evaluated by 4 plastic surgeons. Two independent evaluations were made by each surgeon in 1-month interval using these classification systems. RESULTS: Total number of upper extremity anomalies recorded was 1050. Of the 711 patients operated on, 122 had bilateral anomalies. The anomalies were identified in 833 extremities because many extremities had more than a single diagnosis. We were able to classify all of the anomalies within the OMT classification. The OMT classification gives better reliability results compared with the Swanson classification according to intrarater and interrater reliabilities. CONCLUSIONS: Compared with the Swanson classification system based on phenotypic evaluation of the extremity, the OMT classification system is easier to apply and the association of the anomaly with the embryologic origin during evaluation is possible. We believe that multiple studies from different centers will boost the international acceptance of the OMT classification.

BACKGROUND: Regardless of the technique chosen to treat the aging midface, the isolated lateral approach facelift has a limited impact on the midface volume deficit. In an effort to overcome this limitation, modern facial rejuvenation procedures incorporate an additional modality for replenishing the midface volume. Some of the author's facelift patients present with bulging buccal fat pads despite volume deficiency in the inframalar region. The author's technique is designed to utilize the buccal fat pad to replenish the inframalar volume deficit. OBJECTIVES: The author sought to present the fat pad transposition surgical technique along with objective outcome data. METHODS: This study was a retrospective review of nonconsecutive cases where the sub-superficial-musculo-aponeurotic-system transposition of the buccal fat pad was performed. A total of 22 patients underwent the fat pad transposition technique by the author (O.B.) between July 2013 and December 2017. Patient data were obtained from patient records, 3-dimensional models, magnetic resonance images, and standardized photography. Preoperative differences in midface volume were assessed utilizing curvilinear surface measurements on 3-dimensional models and the Allergan midface volume deficit scale on standardized photography. RESULTS: The average midface volume deficit score significantly improved, and the average midfacial curvilinear surface measurement significantly increased after surgery. Magnetic resonance imaging confirmed a stable position of the buccal fat pad after surgery. CONCLUSIONS: The sub-superficial-musculo-aponeurotic-system transposition of the buccal fat pad is an effective technique that can be safely employed for autologous inframalar augmentation in patients with a favorable facial morphology.

Although extracorporeal septorhinoplasty is the most powerful technique for correcting deviated and leaning noses, many investigators have abandoned it because of keystone problems. The authors defined a new neoseptum fixation technique and used it in 10 patients in 2016. Preoperative and postoperative Nasal Obstruction Symptom Evaluation scale and peak nasal inspiratory flow measurement, and septal indexes of the patients were compared. There was statistically significant improvement in the respiratory condition of all patients. No recurrence or dorsal irregularity has been observed. This new, easily applicable, and robust fixation method of extracorporeal septorhinoplasty may be a definitive solution to prevent keystone irregularities. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

BACKGROUND: The junction between upper and lower lateral cartilages, known as "the scroll area," is an important determinant of the spatial relationship between the middle and lower nasal thirds. OBJECTIVES: We offer a graduated and reproducible surgical technique of scroll area management that takes into consideration anatomic, functional, and aesthetic relationships. METHODS: This study was a retrospective review of the recorded intraoperative information to investigate the frequency of the use of scroll reconstruction techniques and perioperative parameters that relate to unintended component alterations in the scroll area. A total of 364 consecutive primary open approach rhinoplasty cases performed by the first author (O.B.) between July 2011 and September 2015 were included in the study. RESULTS: Of the 364 cases who underwent primary open approach rhinoplasty, 329 received some form of scroll reconstruction. Scroll reconstruction was performed in all deviated cases, and 88% of straight noses. The most common technique for scroll reconstruction was overlapping repair (88.3%). As expected, both alar rim and alar crease asymmetries were very frequent in the deviated nose group, 89.4% and 75% respectively. Alar rim and alar crease asymmetries were frequent enough in the straight nose group to deserve special attention, 14.2% and 10.4% respectively. CONCLUSIONS: With careful attention to anatomic details of the scroll area, nasal tip refinements can be performed with predictable safety and accuracy. Our approach is a graduated, reproducible, and individualized way of scroll area management that aims to create the ideal cartilage configuration while preventing unintended component alterations.

Background: Congenital, traumatic, or developmental bony vault deformities may require additional interventions rather than classical osteotomies to correct the surface structure or angulations of the nasal bones in rhinoplasty. Objectives: The aim of the study was to determine the effects of the additional osteotomies applied for the correction of the nasal vault asymmetries retrospectively. Methods: Twenty-one patients among 512 primary rhinoplasty cases between 2011 and 2016 with bony vault asymmetries were included in the study. Three patients had bilateral convex, 6 patients had unilateral convex, and 7 patients had unilateral concave surface deformities. Five patients had concave deformity on one side and convex deformity on the other side. Double-layer lateral osteotomies and caudal transverse osteotomies were conducted for the correction of the severe surface anatomy deformities of the nasal bones. The caudal transverse osteotomy was delicately performed with a special osteotome, which was designed to protect inner periosteum and mucosa of the nasal bone, and to prevent uncontrolled fracture formation with thinned edge. Results: Twenty patients (95.2%) had favorable results with restoration of a symmetric bony and cartilaginous nasal vault configuration. None of the bone fragments showed any rotation or malposition. One (4.8%) patient with a crooked nose had suboptimal dorsal geometry without requiring revisional surgery at the level of the cartilaginous nasal vault. Conclusions: The author described the morphology, clinical relevance, and correction methods of the nasal vault and the changes that occur in this area during rhinoplasty in patients with concave, convex, or combined three-dimensional nasal bone deformities. Level of Evidence: 4.

Background: The effect of a spreader flap on the keystone area and the upper bony vault depends on the structural strength and cephalic extent of upper lateral cartilages, both of which can be significantly variable among individuals. Objectives: The authors present a novel cephalically extended osseocartilaginous composite spreader flap technique that was designed to overcome the limitations of a conventional spreader flap on the keystone area upper bony vault, in patients with cephalically short and structurally weak upper lateral cartilages and thin nasal bones. Methods: This study was a retrospective review of the recorded perioperative information to investigate the frequency of the use of the composite spreader flap technique and perioperative parameters that relate to postoperative dorsal deformities. One-hundred-seventy-six consecutive primary open approach rhinoplasty cases performed by the first author (O.B.) between November 2015 and February 2017 were included in the study. Patient data were obtained from rhinoplasty data sheets, standardized photographs, and postoperative physical examinations. Results: Of the 176 cases who underwent primary open approach rhinoplasty whose data were reviewed for the purpose of this study, 38 (32 females, 6 males) had dorsal reconstruction with the use of a composite spreader flap. Seventeen patients had a deviated nose with an asymmetric bony pyramid. In 8 patients, the composite spreader flap was used unilaterally. No patients in the composite spreader flap group had a postoperative dorsal deformity or required surgical revision. Conclusions: Composite flap preparation extends the reliability and the reach of the spreader flap technique beyond its previous borders.

Composite scalp and cranium defects, which require microsurgical reconstruction, result from tumor resection, radiation, trauma, severe burn injuries, and rarely vasculitic disorders. In the current study, the authors aim to compare the outcomes of the fasciocutaneous flaps and musculocutaneous free flaps used for the reconstruction of extensive composite scalp and cranium defects. From 2010 to 2017, 21 patients who underwent composite scalp and cranium defect reconstruction with a free flap were retrospectively identified. Eighteen patients had squamous cell carcinoma, 2 patients had meningioma, and 1 patient had Ewing sarcoma. Thirteen musculocutaneous free flaps including latissimus dorsi and vertical rectus abdominis flaps and 9 free fasciocutaneous flaps including radial forearm and anterolateral thigh flaps were used. Only 1 flap loss was encountered. No neurologic impairment in postoperative period was reported. The mean length of stay in the hospital, the duration of surgery, and total volume of blood transfusion for the fasciocutaneous flap group were significantly shorter than those for musculocutaneous flap group. No flap atrophy was reported in fasciocutaneous flap group. Reconstruction of the composite scalp and cranium defects with fasciocutaneous free flaps allows shorter hospitalization, less blood transfusion and less flap atrophy than those of musculocutaneous flaps. To this respect, their usage should be prioritized in such challenging patients.

Smoking is a leading cause of flap failure. Varenicline-assisted smoking cessation has shown beneficial effects on vascular endothelial function. The aim of this study was to determine whether varenicline conveys beneficial effects for skin flap survival. Twenty-four rats were randomly divided into four groups of six. The rats in the control group received normal saline subcutaneous injections, and those in the nicotine group received subcutaneous nicotine injections. The rats in the varenicline group received varenicline intraperitoneally, and those in the nicotine-varenicline group received both nicotine and varenicline. At the end of week 3, the dorsal skin flaps were raised in all rats. On postoperative day 7, the flaps were evaluated by direct observation, microangiography, and light microscopy. The mean necrotic area of the flaps was significantly greater in the nicotine group than in the control group (49.2 ± 4.71 vs. 22.03 ± 0.93%, respectively, p < .01) and significantly higher in the nicotine-varenicline group than in the varenicline group (22.4 ± 1.23 vs. 9.2 ± 0.59%, respectively, p < .01). However, no significant difference was observed between the control and nicotine-varenicline groups (p = .934). Microangiographically, vascularity was lowest in the nicotine group and highest in the varenicline group. Histologically, larger areas of necrosis, more severe inflammation and less vessel formation were observed in the nicotine group. Healing, exhibited by a greater number of vessels, was evident in the varenicline-applied groups. Varenicline appears to increase the microcirculation of random flaps, as shown by decreased flap necrosis and increased vascularity.
