Introduction: The large mixture of races in Brazil gives the nose its distinctive composition, which makes rhinoplasty difficult for these patients. Every patient should have their anatomy thoroughly examined on an individual basis, as there is no unique strategy that works for all situations., Methodology: This is a narrative overview of the last 10 years' worth of literature that describes the ethnic traits of each nose, with a particular emphasis on the Brazilian nose, and talks about the major surgical approaches that can be applied in these situations., Results: The low dorsum, broad nasal bones, thick skin, and bulbous tip are the primary features of the Brazilian nose. Many times, lateral osteotomies, root grafting, isotretinoin treatment for skin thickness, and neodomus formation are required., Conclusion: The Brazilian nose presents a surgical challenge that calls for the mastery of multiple procedures, not simply structured rhinoplasty. In certain cases, preservation rhinoplasty may even be used., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Background: Osteotomies are important maneuvers in the plastic surgeon's arsenal for the nasal dorsum treatment. However, there is a concern regarding a possible medialization of the inferior turbinate's heads and narrowing of the internal nasal valve if the Webster's triangle is not preserved., Objectives: To analyze the mobilization of the inferior turbinates during primary rhinoplasty after lateral osteotomies., Methods: This is a retrospective study in which we analyzed 37 patients who underwent very low-to-low osteotomies in our service, during primary rhinoplasties. Axial and coronal computed tomography scans were obtained, and preoperative and 6 months postoperative images were compared with Radiant DICOM Viewer software (Medixant, Poznan, Poland) in 3-dimensional multiplanar reconstruction., Results: There were no statistically significant differences between preoperative and postoperative measurements of the lower turbinate's osseous bases, both in axial ( P = .305) and coronal ( P = .08) images., Conclusions: Low-to-low osteotomies showed no medialization of the inferior turbinate's heads or narrowing of the internal nasal valve in this study., (© The Author(s) 2024.

Background: The most accurate methods for assessing fat grafted volume, such as computed tomography (CT) scan and magnetic resonance imaging, use 3-dimensional (3D) evaluation of the recipient area. Currently, other measurement techniques such as photogrammetry (compilation of photos) are employed., Objectives: The aim of the present study was to compare 3D images obtained by CT scan with those obtained by photogrammetry in patients undergoing autogenous fat grafting to the chin., Methods: A prospective longitudinal study was undertaken to assess patients undergoing autologous fat grafting to the chin, capturing preoperative and postoperative (6 months) images with CT scan and photogrammetry. Captured images were submitted to 3D reconstruction with Blender image software., Results: A total of 40 patients were submitted to surgery. Seventy-five percent were female. Median age and BMI were 26.5 years and 23.6 kg/m2, respectively. Median volume of fat grafted was 10 mL (interquartile range 8-12.25 mL). Results showed that the median preoperative volume measured by CT scan was larger than the photogrammetry measurement (12.48 mL vs 12.01 mL, respectively, P < .001). Likewise, a larger volume was measured by CT scan than by photogrammetry (15.54 mL vs 14.94 mL respectively, P < .001) 6 months postoperatively. However, there was no difference between CT scan and photogrammetry measurements of the change in volume from preoperatively to postoperatively (P = .89)., Conclusions: There was no agreement between fat graft volume measurements obtained by 3D photogrammetry and CT scan techniques with regard to absolute values of fat graft volume measurements, however no difference was found between the 2 methods when comparing preoperative with postoperative fat graft volume variation., (© The Author(s) 2022.

Brazil has always been a fertile place for plastic surgery techniques, especially cosmetic, and it was not different in rhinoplasty. In Brazil surgeons started using the dorsal preservation rhinoplasty in the 1970s. Techniques have changed, the problems and contraindications were challenged, and solutions proposed. As a result, indications were expanded to almost every kind of nose. Surface working executed with power tools, such as the piezoelectric device and the power drill, complemented the techniques and allowed for refinement in execution. Today the Brazilian preservation techniques are adopted and improved by many surgeons around the world., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Summary: For V-shaped nasal bones, the authors consider that ostectomy of the dorsal keystone area can be avoided, and this has led to the development of a new preservation technique: the spare roof technique B (or Ferreira-Ishida technique), where the bony cap is preserved. It includes six main steps, as follows. Step 1, draw on the surface of the skin the desired dorsal brow-tip aesthetic lines, the pyriform aperture, the rhinion, and the amount of triangular bone that has to be taken out to allow pushing-down the bony cap, and the transversal line in the beginning of the nasal hump. Step 2, release the upper lateral cartilages from the dorsal septum ("high septal strip"). Step 3, take out the amount of dorsal septum necessary to dehump. Step 4, perform the paramedian high parallel osteotomies exactly below the marked brow-tip dorsal aesthetic lines. Then, perform the second group of lower osteotomies, until the E-point, to achieve a triangular shape of bone in each side of the bony cap. Perform the ostectomy of the mentioned triangular areas. Release the lateral keystone area. Perform partial ultrasonic ostectomy endonasally, below the nasal bones, to promote the weakening of the transverse fracture line, in the sagittal plane just above the E-point. Push-down gently the rectangular bony cap with a Luc nasal forceps (19 cm) in a greenstick fashion. Perform lateral traditional osteotomies from high to low to high to narrow the bony bridge as much as is needed. Step 5, perform a regular L-shape Cottle septoplasty (if necessary). Step 6, suture the cartilaginous middle vault (upper lateral cartilages) to the dorsal aspect of the remaining septum., Competing Interests: Disclosure:The authors declare that they have no conflicts of interest to report., (Copyright © 2022 by the American Society of Plastic Surgeons.)

Background: Classic nasal hump reduction based on partial resection of the cartilage and bones in the nose may lead to dorsum deformities such as an inverted-V deformity, irregularities, and an open roof. Techniques that preserve the nasal dorsum (namely the push-down and let-down) avoid these problems, but may not always be indicated for very large, broad, or deviated noses, whereas cartilaginous push-down is also indicated for large and deviated humps. Because only the cartilaginous portion of the hump is preserved in the cartilaginous push-down, a rough area may remain where the bony portion is resected., Objectives: The aim of this study was to develop a variation of the cartilaginous push-down technique which includes a bony cap to preserve the smoothness of the keystone area during nasal hump treatment., Methods: Forty-eight consecutive patients with indication for nasal hump treatment who underwent cartilaginous push-down procedures with bony cap preservation between August 2018 and October 2019 were studied., Results: We observed related complications in 2 patients (4.2%); in 1 patient (2.1%) the bony cap was lost during the rasping of the nasal bones and the surgery was altered to utilize only the cartilaginous push-down. Another patient (2.1%) experienced a mild hump recurrence during the early weeks following the procedure. All of the remaining patients had their nasal humps treated adequately., Conclusions: The nasal hump was adequately corrected in most of the study patients (95.8%). Preserving the bony cap while performing the cartilaginous push-down may prevent complications related to the osseous resection of the keystone area., (© 2020 The Aesthetic Society.)

Background: Patient-reported outcomes measurement instruments (PRO) are a good way to measure results after aesthetic procedures. FACE-Q is a systematized and standardized PRO tool and was not available in Portuguese., Methods: This cross-sectional study included four stages: translation of FACE-Q, backtranslation, testing in patients who underwent facial aesthetic procedures and review of the questionnaires between September and December, 2018. Guidelines merging WHO and ISPOR's rules were followed., Results: Translation was conducted by two translators, resulting in two versions, translation A and translation B, which were reconciled to generate the first Portuguese version. Reconciliation showed inconsistencies between TA and TB in 63% (n = 222) of the 353 questions, which were solved by maintaining TA in 25% of cases (n = 87), TB in 27% and a new version in 11% (n = 40) of the questions. Backtranslation showed written differences with the original FACE-Q in 64 (22.7%) of the 353 question, but only one case of semantic difference, which was corrected resulting in production of the second Portuguese version. Seven patients with a mean age of 35.8 years were interviewed to assess the difficulty in understanding the questionnaires. Four patients had no or minor difficulties understanding the questionnaire, and the other three had difficulties and suggested changes that led to a third Portuguese version. The third version was reviewed for grammar and spelling resulting in the final Portuguese version., Conclusion: A Brazilian Portuguese version of the FACE-Q questionnaire was obtained maintaining equivalency with the source instrument. This will allow cross-cultural research and comparison of results between different studies., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Statement of Problem: The correct positioning of the microvascular-free fibula flap (MFFF) is essential for satisfactory mandibular reconstruction. However, the effect of acrylic resin-based surgical guides on prosthetic rehabilitations has not yet been properly investigated., Purpose: The purpose of this randomized clinical trial was to evaluate whether intraoral and extraoral acrylic resin-based surgical guides improve anatomic, functional, esthetic, and quality of life (QoL) results for dental prosthetic rehabilitation with MFFF., Material and Methods: Participants subjected to mandibular reconstruction with MFFF were selected and randomly distributed into 2 groups, control (Co; using conventional surgery) and acrylic resin-based surgical guides (Sg). Functional parameters related to prosthetic rehabilitation and QoL were evaluated by interviews and an oral health impact profile (OHIP)-14 questionnaire. Functional parameters and questionnaire scores were subjected to statistical analysis: the likelihood ratio and the Fisher exact and Mann-Whitney U tests (α=.05)., Results: Of 40 participants, 18 were rehabilitated, 10 with tooth-tissue-supported partial removable dentures and 8 with implant prostheses. In Sg, the study measured an enhancement in functional parameters and revealed a significant improvement in QoL (P=.020)., Conclusions: The guides proposed directly improved mandibular reconstruction. Functional aspects may be improved by allowing good intermaxillary relationships and posterior dental rehabilitation. Functional success is directly dependent on soft tissue status and the quality of its reconstruction. Soft tissue evaluation is important before dental rehabilitation., (Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc. All rights reserved.)

The supraclavicular island flap has been widely used in head and neck reconstruction, providing an alternative to the traditional techniques like regional or free flaps, mainly because of its thin skin island tissue and reliable vascularity. Head and neck patients who require large reconstructions usually present poor clinical and healing conditions. An early experience using this flap for late-stage head and neck tumour treatment is reported. Forty-seven supraclavicular artery flaps were used to treat head and neck oncologic defects after cutaneous, intraoral and pharyngeal tumour resections. Dissection time, complications, donor and reconstructed area outcomes were assessed. The mean time for harvesting the flaps was 50 min by the senior author. All donor sites were closed primarily. Three cases of laryngopharyngectomy reconstruction developed a small controlled (salivary) leak that was resolved with conservative measures. Small or no strictures were detected on radiologic swallowing examinations and all patients regained normal swallowing function. Five patients developed donor site dehiscence. These wounds were treated with regular dressing until healing was complete. There were four distal flap necroses in this series. These necroses were debrided and closed primarily. The supraclavicular flap is pliable for head and neck oncologic reconstruction in late-stage patients. High-risk patients and modified radical neck dissection are not contraindications for its use. The absence of the need to isolate the pedicle offers quick and reliable harvesting. The arc of rotation on the base of the neck provides adequate length for pharyngeal, oral lining and to reconstruct the middle and superior third of the face., (Copyright © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Protrusion of the abdominal wall secondary to abdominoplasty may occur in patients with weakness of the aponeurotic structures. The anterior layer of the rectus abdominis muscle consists of fibers that are transverse rather than vertical. Based on this anatomical feature, vertical sutures are suggested for the correction of diastasis recti, since they include a greater amount of fascial fibers and thus would be more resistant to tensile strength than horizontal ones., Methods: The anterior layers of the rectus abdominis muscles of 15 fresh cadavers were dissected. Two vertical lines were marked on each side of the linea alba, corresponding to the site where plication is usually performed in abdominoplasties. Three abdominal levels were evaluated: the supraumbilical, umbilical, and infraumbilical levels. A simple suture was placed in the vertical direction in one group and in the horizontal direction in the other group, at each of the three levels previously described. These sutures were connected to a dynamometer, which was pulled medially toward the linea alba until rupture of the aponeurosis occurred., Results: The mean strength required to rupture the aponeurotic structures in which the vertical sutures had been placed was greater than for the horizontal ones (p < 0.0001)., Conclusion: The vertical suture of the rectus abdominis sheaths was stronger than the horizontal suture because of the more transversal arrangement of its aponeurotic fibers. Thus, routine use of the vertical suture in plications of the aponeurosis of the rectus abdominis muscles is suggested.

Background: The use of synthetic mesh for abdominal wall closure after removal of the rectus abdominis is established but not standardised. This study compares two forms of mesh fixation: a simple suture, which fixes the mesh to the edges of the defect on the anterior rectus abdominis fascia; and total fixation, which incorporates the fasciae of the internal oblique, external oblique and transverse muscles in the suture, anchoring the mesh in the position of the removed muscle., Method: A total of 16 fresh cadavers were dissected. Two sutures were compared: simple and total. Three different sites were analysed: 5 cm above, 5 cm below and at the level of the umbilicus. The two sutures compared were tested in each region using a standardised technique. All sutures were performed with nylon 0, perpendicular to the linea alba. Each suture was secured to a dynamometer, which was pulled perpendicularly towards the midline until the rupture of the aponeurosis. 'Rupture resistance' was measured in kilogram force. The mean among the groups was compared using the paired Student's t-test to a significance level of 1% (p<0.01)., Results: The mean rupture resistance of the total suture was 160% higher than that of the simple suture., Conclusion: The total suture includes the external oblique, internal oblique and transverse fasciae, which are multi-directional, and creates a much higher resistance when compared with the simple suture. Total suture may reduce the incidence of bulging and hernias of the abdominal wall after harvesting the rectus abdominis muscle, but comparative clinical studies are necessary., (Copyright © 2010 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Treatment of excessive gingival display usually involves procedures such as Le Fort impaction or maxillary gingivectomies. The authors propose an alternative technique that reduces the muscular function of the elevator of the upper lip muscle and repositioning of the upper lip., Methods: Fourteen female patients with excessive gingival exposure were operated on between February of 2008 and March of 2009. They were filmed before and at least 6 months after the procedure. They were asked to perform their fullest smile, and the maximum gingival exposures were measured and analyzed using ImageJ software. Patients were operated on under local anesthesia. Their gingival mucosa was freed from the maxilla using a periosteum elevator. Skin and subcutaneous tissue were dissected bluntly from the underlying musculature of the upper lip. A frenuloplasty was performed to lengthen the upper lip. Both levator labii superioris muscles were dissected and divided., Results: The postoperative course was uneventful in all of the patients. The mean gingival exposure before surgery was 5.22 +/- 1.48 mm; 6 months after surgery, it was 1.91 +/- 1.50 mm. The mean gingival exposure reduction was 3.31 +/- 1.05 mm (p < 0.001), ranging from 1.59 to 4.83 mm., Conclusion: This study shows that the proposed technique was efficient in reducing the amount of exposed gum during smile in all patients in this series.

Background: During the past 15 years, polymethylmethacrylate has been used as a synthetic permanent filler for soft-tissue augmentation., Methods: This article reports 32 cases of complications seen at Hospital das Clínicas, Faculty of Medicine, University of São Paulo, for procedures performed elsewhere., Results: The average age of the patients was 43.6 years (range, 22 to 70 years). Twenty-five patients were women. Sixteen injection procedures were performed by certified plastic surgeons, nine by dermatologists, two by urologists, and one by a nonphysician. Complications were classified into five groups according to main presentation as follows: tissue necrosis (five cases), an acute complication that can be related to technical mistakes but that can also be dependent on patient factors or caused by local infection; granuloma (10 cases), which usually presents as a subacute complication 6 to 12 months after the procedure; chronic inflammatory reactions (10 cases), which usually occur years later and can be related to a triggering event, such as another operation or infection in the area that was injected (these reactions are immunogenic in origin and may have cyclic periods of activation and remission); chronic inflammatory reaction in the lips (six cases), which may be present with severe symptoms, especially with lymphedema, because of mobility of the lip; and infections (one case), which are rare but possible complications after filling procedures., Conclusions: Polymethylmethacrylate filler complications, despite being rare, are often permanent and difficult or even impossible to treat. Safety guidelines should be observed when considering use of polymethylmethacrylate for augmentation.

The cartilaginous structures of the nose play an important role in nasal esthetics and function. The handling of these structures has always been very treacherous, and long-term follow-up quite often has shown unexpected results. Based on Gibson's studies, we propose the use of abrasion treatment of the nasal cartilages with the burr power drill. This device can produce controlled weakening on determined regions of the nasal cartilages. If this weakening is done on just one side, the cartilage will bend to the opposite side. On the septal cartilage, this method can be used to straighten it by abrasion on its concave portion. To correct the alar cartilages, the burring is done either to enhance curvatures or to change the conformation of the alar cartilage itself. This method was used in 67 patients with satisfactory results, permitting corrections of septal deviations with very little resections of the septal cartilages and corrections of various tip deformities, with almost no resections at all of the alar cartilages.

Background: In advanced head and neck tumors margins are very rarely comprehensively checked by frozen sections. The goal of this study was to analyze a new proposal for harvesting margins using a double-bladed scalpel., Methods: Thirty-eight patients underwent a comprehensive resection of advanced head and neck tumors with a double-bladed scalpel. Margins were mapped and checked by frozen sections, while tumor resection continued. When positive margins were identified, they were excised again, and checked by frozen sections., Results: Thirty-three patients (87%) had clear skin and soft tissue margins at frozen sections. Five patients (13%) had focal skin and soft tissue-positive margins at frozen sections, which were re-excised. Two patients (5%) had skin and soft tissue-positive margins only at permanent sections. One was reoperated and 1 received radiation therapy. The 3-year local control rate was 58%., Conclusions: In this preliminary study, the double-bladed scalpel appeared to be an interesting option for complete intraoperative evaluation of surgical margins of advanced head and neck tumors., (Copyright 2006 S.

The absence of nipple-areola complex is a rare entity and is always associated with other anomalies. This paper described a case of bilateral athelia without other alterations. The atrophy of the dense mesenchyme due to absence of parathyroid hormone-related protein produced in epithelium may lead to nipple involution. Further cases should be studied to corroborate this theory.

The alar cartilage is a unique structure that supports the tip of the nose, keeps the external valve open, and plays an important role in tip aesthetics. Very often the plastic surgeon needs to reconstruct this cartilage, as in secondary rhinoplasties when the lower lateral cartilage is overresected. Many authors have described cartilage grafts taken from the ear and septum, mounted and stitched in various manners, with some very good results. In patients with thin skin, though, any irregularity or distortion in the grafts becomes visible after a short time postoperatively. The authors present an alternative to reconstructing alar cartilage symmetrically using one graft. This graft is obtained by shaping septal cartilage in an "L" form, with a 135-deg angle (instead of a 90-deg angle) between its legs, and then splitting the smaller leg, obtaining a strut from the longer leg and two "lateral crura" from the shorter leg.

Classically, nasal hump reduction is based on the partial resection of the cartilages and bones of the nose, as it was described by Joseph almost a century ago. The cartilaginous portion of the hump consists of a single unity formed by the two upper lateral cartilages and the septal cartilage. During hump reduction in the classic rhinoplasty, this structure is slashed in three pieces, which is the main cause of irregularities, shadows, and pinchings over the long-term results. Late follow-ups of the classical hump removal often show an inverted V-shaped shadow on the dorsum secondary to the destruction of the osseous-cartilaginous transition. The angle and relation between the septal and upper lateral cartilages are reduced, which may compromise the functional aspect. The destruction of the unique anatomy of the cartilaginous hump is one of the main causes of this functional and aesthetic sequela. Here, we present a technique that preserves the cartilaginous framework of the nasal hump by lowering it through the resection of a strip of septum, avoiding the problems described above.

To determine whether the lamina tragi, isthmus, and cavum conchae are a donor area for reconstruction of the alar cartilage with all its elements (medial crus, junction of the medial and lateral crura, and lateral crus), with the same dimension and en bloc, 40 alar cartilages and 40 lower parts of ear cartilages of 20 cadavers were dissected. Several measurements were taken in the alar cartilages, such as distance, thickness, and angle. Then they were compared with the measurements performed in the ear cartilages and segments removed from the lamina tragi, isthmus, and cavum conchae. This study, done with cadavers, shows that from the lamina tragi, isthmus, and cavum conchae, en bloc resection is possible with characteristics of form and dimension similar to those of the homolateral alar cartilage. The segment removed en bloc from the intermediate part of the lamina tragi, isthmus, and cavum conchae replaces, respectively, the medial crus, junction of the medial and lateral crura, and lateral crus.

Presentation of 62 cases of secondary nasal deformities treated by external incision. Several types of endonasal deformities were observed, properly classified and repaired. When excessive resection was observed, local cartilage graft, septonasal or conchal types were employed.

A new technique is described for increasing the nasal tip by using an en bloc autogenous ear cartilage graft in such a manner as to create, in essence, a replacement of the entire ipsilateral alar cartilage.
