Hybrid Dorsal Preservation Rhinoplasty: Reediting an Aesthetic Dorsum.

BACKGROUND: The prerequisite of a well-shaped dorsum with proper dorsal aesthetic lines that needs no modifications in its width and symmetry is key to letdown and push-down techniques as classically described. The common current concept is that total preservation of the middle vault is obligatory. This, however, obviously limits the indications, since nasal dorsum with natural aesthetic dorsal lines per se is relatively few. The recent, impressive, revival of letdown and push-down procedures has progressively generated numerous technical variations, but all those essentially still left the middle vault unmodified. The concept of splitting the middle vault and modifying its width and symmetry, while leaving the crucial dorsal (central) and lateral Keystone area intact, represents a new hybrid approach to the nasal dorsum. The structural benefits of classical component separation are combined with the major advantage of preserving the flexible chondro-osseous joint at the keystone junction. Osteotomies and/or osteoplasty can be done as necessary to modify the bony dorsum and at the same time any type of septal deformity can be addressed according to the time-tested L-strut principle, a Cottle septoplasty included. This hybrid approach expands indications beyond those of the conventional push-down/letdown technique, including moderate asymmetries of the bony and cartilaginous dorsum. Although splitting the middle vault along the septal T will also facilitate middle vault reshaping in cases where a full letdown procedure is indicated, this paper will clarity address only those instances where no circumferential osteotomy is done. METHODS AND MATERIALS: The dorsal bony nasal pyramid is always addressed first by rhinosculpture (osteoplasty) with piezoelectric inserts and/or burrs, in combination with different types of osteotomies as needed. This will allow narrowing of the bridge and correction of bony asymmetries. The osseous-cartilaginous connection of the central dorsal keystone area (DKA) is totally preserved. At this point, three main variations are possible: Type 1) preservation of the septal T and push-down by a high-middle septal strip resection, two different variations (1A and 1B) are possible here, Type 2) reduction in width of the septal T-segment and middle vault restoration by spreader flaps without any push-down of the septal T and Type 3) preservation of the septal T and letdown by low strip resection. CONCLUSION: Hybrid Dorsal Preservation involves concepts of Structure and Preservation Rhinoplasty. Dorsal and lateral keystone area are preserved, and the middle vault could be modified splitting the septal T in the anatomical plane, expanding patient indications and improve outcomes.

The Resting Angle Suture.

SUMMARY: The goal of every rhinoplasty surgeon is to create a functional and aesthetically pleasing nose. The lateral crura resting angle, a recently described key concept, should be taken into consideration to achieve a satisfactory result. In this article, the authors describe the resting-angle suture, a novel technique derived from the inversion suture used to correct ectropion deformity in lower eyelid surgery.

Weekend warrior exercise model for protection from chronic mild stress­induced depression and ongoing cognitive impairment.

We aim to investigate the role and biological mechanisms of the weekend warrior (WW) exercise model on depression­induced rats in comparison to the continuous exercise (CE) model. Sedentary, WW, and CE rats were subjected to chronic mild stress (CMS) procedure. CMS and exercise protocols continued for six weeks. Anhedonia was evaluated by sucrose preference, depressive behavior by Porsolt, cognitive functions by object recognition and passive avoidance, and anxiety levels by open field and elevated plus maze. After behavioral assessments, brain tissue myeloperoxidase (MPO) activity, malondialdehyde (MDA) levels, superoxide dismutase and catalase activities and GSH content, tumor necrosis factor­α (TNF­α), interleukin­6 (IL­6), IL­1ß, cortisol and brain­derived neurotrophic factor levels and histological damage was assessed. CMS­induced depression­like outcomes with increases in anhedonia and decreases in cognitive measures that are rescued with both exercise models. The increased immobilization time in the Porsolt test was decreased with only WW. Exercise also normalized the suppression of antioxidant capacity and MPO increase induced by CMS in both exercise models. MDA levels also declined with both exercise models. Anxiety­like behavior, cortisol levels, and histological damage scores were exacerbated with depression and improved by both exercise models. TNF­α levels were depleted with both exercise models, and IL­6 only with WW. WW was as protective as CE in CMS­induced depression­like cognitive and behavioral changes via suppressing inflammatory processes and improving antioxidant capacity.

My Approach to Preservation Rhinoplasty.

Preservation rhinoplasty entails the preservation of the supportive ligaments, preservation of the cartilage structure, and preserving the anatomy of the nasal dorsum. The preservation methods I use are described in this article.

Rhinoplasty Dissection Planes (Subcutaneous, Sub-SMAS, Supra-perichondral, and Sub-perichondral) and Soft Tissues Management.

Rhinoplasty as an operation is akin to a game of chess, where every maneuver will influence the eventual outcome. Undoubtedly, more than one approach to the nasal soft tissues envelop can produce beautiful and safe results as will be described in the paper namely, the subcutaneous, sub-superficial musculoaponeurotic system, supra- and sub-perichondral planes. For different justifiable reasons surgeons have their preferences, regarding dissection planes on the tip, middle and upper thirds, and regarding the manipulation of the soft tissue layers and nasal ligaments. The concept of the nasal layers and the presence of relevant ligamentous structures and how to restore them in an anatomical fashion, will help to understand the logic behind various approaches.

Key Points in Subperichondrial-Subperiosteal Dissection.

"Subperichondrial-subperiosteal dissection technique (SSDT) decreases soft tissue injury to a minimum by protecting soft tissues from dissection and retraction traumas. The fact remains that dissecting the perichondrium of the nasal tip cartilages is not effortless. Cartilages may be harmed if dissection is not initiated at the right location. The aforementioned surgeons have routinely used the SSDT between the years 2008 and 2019 in more than 4000 rhinoplasties. The number of the surgeons making use of the SSDT will increase with the understanding of the key points in dissection, their ordering, and use of correct instrumentation."

Auto-Rim Flap Technique for Lateral Crura Caudal Excess Treatment.

BACKGROUND: There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities. OBJECTIVES: In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties. METHODS: The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions. RESULTS: Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position. CONCLUSIONS: With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary. LEVEL OF EVIDENCE: 4 Therapeutic.

Surface Aesthetics and Analysis.

Surface aesthetics of an attractive nose result from certain lines, shadows, and highlights with specific proportions and breakpoints. Analysis emphasizes geometric polygons as aesthetic subunits. Evaluation of the complete nasal surface aesthetics is achieved using geometric polygons to define the existing deformity and aesthetic goals. The relationship between the dome triangles, interdomal triangle, facet polygons, and infralobular polygon are integrated to form the "diamond shape" light reflection on the nasal tip. The principles of geometric polygons allow the surgeon to analyze the deformities of the nose, define an operative plan to achieve specific goals, and select the appropriate operative technique.

Surface Aesthetics in Tip Rhinoplasty: A Step-by-Step Guide.

Tip rhinoplasty is a key component of aesthetic rhinoplasty. An understanding of the correlation between tip surface aesthetics and the underlying anatomic structures enables proper identification and correction of tip abnormalities. Surface aesthetics of the attractive nose are created by certain lines, shadows, and highlights with specific proportions and breakpoints. In this Featured Operative Technique, the authors describe a stepwise process for tip rhinoplasty that conceptualizes aesthetic subunits as geometric polygons to define the existing deformity, the operative plan, and the aesthetic goals. Tip rhinoplasty is described in detail, from initial markings through incisions and dissection. The autorim graft concept is explained, and lateral crural steal and footplate setback techniques are described for the attainment of symmetric domes with correct lateral crural resting angles. Methods in columellar reconstruction are described, including creating the columella (C') breakpoint and the infralobular caudal contour graft. The principal author (B.Ç.) has applied these techniques to 257 consecutive "polygon rhinoplasties" over the past 3 years.

Bone dust and diced cartilage combined with blood glue: a practical technique for dorsum enhancement.

UNLABELLED: The combination of dorsal nasal reconstruction and camouflage of surface irregularities is an important step in rhinoplasty. We hereby present our technique of delivering diced cartilage in combination with bone dust to the nasal dorsum using the patient's blood as a carrier. We advocate use of an autologous material (blood) as a scaffold for graft delivery, dismissing the use of a foreign material or fascial wrapping of the graft. Using the patient's blood for this purpose not only stabilizes the graft into a malleable structure that is easily applicable to the nasal dorsum, it also decreases the potential for reaction against foreign material.

Rhinoplasty and brow modification: a powerful combination.

BACKGROUND: Plastic surgeons have long recognized the importance of performing chin augmentation concurrent with a rhinoplasty to achieve facial balance. However, few surgeons consider the benefits of combining a rhinoplasty with brow modification to achieve a better aesthetic result. By increasing the size of the middle third of the face, the nose will automatically appear smaller. OBJECTIVE: The authors describe anatomical dissections that provided perspective on the facial anatomy of the areas being studied and report the results of concurrent browlift and rhinoplasty procedures in a retrospective series of patients. METHODS: The present study consisted of 2 parts: anatomical dissections and a retrospective chart review. The nose and central forehead area were dissected in 7 fresh cadavers at the time of autopsy to understand the anatomical relationship between the various muscles in the radix/glabellar region and to assess the muscle resection occurring in the clinical procedures. We also reviewed the charts of 24 patients who underwent combined rhinoplasty and brow modification with the senior author (R.K.D.) during a 2-year period (July 2010 to June 2012). Younger patients underwent a central browlift (CBL) with screw fixation, while older patients (ages 34-60 years) underwent full 5-incision endoscopic forehead lifting. RESULTS: The age range for patients in this series was 14 to 60 years. Two patients were men and 22 were women. There were 12 primary and 12 secondary procedures in the series; 13 patients underwent CBL and 11 had EFL. The mean follow-up was 18 months. One patient had a persistent fluid accumulation in the glabellar region, which required drainage. One patient requested additional refinement of her nasal tip. CONCLUSION: Modification of the central brow can dramatically change the aesthetic polygons of the nose/glabellar region. A CBL with radix/glabellar muscle excision is important in younger patients who need a well-defined nasion and older secondary patients who feel that the upper third of their nose is still heavy. A full EBL can enhance the facial appearance of older patients in whom a rhinoplasty alone would have a modest impact.

Rhinoplasty: surface aesthetics and surgical techniques.

Surface aesthetics of the attractive nose are created by certain lines, shadows, and highlights, with specific proportions and breakpoints. Our evaluation of the nasal surface aesthetics is achieved using the concept of geometric polygons as aesthetic subunits, both to define the existing deformity and the aesthetic goals. Surgical techniques have been developed and modified to achieve the desired surface appearance, and those are detailed in this article. The principles of geometric polygons allow the surgeon to analyze the deformities of the nose, to define an operative plan to achieve specific goals, and to select the appropriate operative technique. These aesthetic concepts and surgical techniques were used in 257 consecutive rhinoplasties performed in the past 3 years by the principal author (B.Ç.).

Acute mercury poisoning among children in two provinces of Turkey.

Elemental mercury exposure occurs frequently and is potentially a toxic, particularly in children. Children are often attracted to elemental mercury because of its color, density, and tendency to form beads. Clinical manifestations of elemental mercury intoxication vary depending on its form, concentration, route of ingestion, and the duration of exposure. We present data on 179 pediatric cases of elemental mercury poisoning from exposure to mercury in schools in two different provinces of Turkey. Of all patients, 160 children had both touched/played with the mercury and inhaled its vapors, while 26 children had only inhaled the mercury vapor, two children reported having tasted the mercury. The median duration of exposure was 5 min (min 1-max 100), and 11 (6 %) children were exposed to the mercury for more than 24 h at home. More than half of the children (51.9 %) were asymptomatic at admission. Headache was the most common presenting complaint. The results of physical and neurological examinations were normal in 80 (44.6 %) children. Mid-dilated/dilated pupils were the most common neurological abnormality, and this sign was present in 90 (50.2 %) children. Mercury levels were measured in 24-h urine samples daily, and it was shown that the median urinary level of mercury was 29.80 µg/L (min, 2.40 µg/L; max, 4,687 µg/L). A positive correlation was also found between the duration of exposure and urinary mercury levels (r = 0.23, p = 0.001). All patients were followed up for 6 months. On the first follow-up visit performed 1 month after discharge, the neurological examinations of all patients were normal except for those patients with peripheral neuropathy and visual field defects. On the last follow-up visit at the sixth month, only two children still experienced visual field defects. In conclusion, this study is one of the largest case series of mercury intoxication of students in schools. Elemental mercury exposure can be potentially toxic, and its symptomatology is variable, particularly in children. Therefore, school staff and children should be aware of the risk of mercury toxicity. Pediatricians also need to warn parents and children about the hazards of playing with any chemical.

A complete subperichondrial dissection technique for rhinoplasty with management of the nasal ligaments.

BACKGROUND: A complete subperichondrial and subperiosteal dissection technique during rhinoplasty may minimize soft tissue disruption, resulting in less scar tissue formation and preservation of ligamentous structures. OBJECTIVES: The authors describe their results with subperichondrial dissection of the nasal framework and manipulation of the preserved nasal ligaments. METHODS: The charts of 228 consecutive patients who underwent rhinoplasty with complete subperichondrial dissection via an open or closed approach between May 2008 and April 2011 with the senior author (BÇ) were retrospectively reviewed. Intraoperatively, the scroll ligament and Pitanguy's midline ligament were repaired to stabilize the internal valve and tip position, respectively. RESULTS: Patients in this series (182 women, 46 men) ranged in age from 18 to 54 years (mean, 24.3 years). A total of 203 procedures were primary rhinoplasties; 14 were secondary, and 11 were revisions. The open approach was used in 92 patients, whereas a closed dome delivery was used in the remaining 136 patients. Follow-up ranged from 9 months to 3 years. A complete subperichondrial dissection technique resulted in relatively limited edema and more rapid patient recovery compared with the authors' previous experience with the sub-superficial musculoaponeurotic system (SMAS) approach. Repeat elevation in the subperichondrial plane was easier and less traumatic in revision cases compared with secondary rhinoplasty cases. CONCLUSIONS: Subperichondrial dissection of the nasal framework allows reshaping and redraping of the nasal tip and controlled manipulation and repair of ligaments without disturbing the overlying soft tissue.

Importance of the levator labii alaeque nasi muscle in dorsal septal deviations.

Deviated cartilages structures of the nose can be affected by nasal muscles, and deviation becomes conspicuous when the patient smiles. This condition depends on activity of nasal muscles, particularly the levator labii alaeque nasi muscle. A total of 124 septorhinoplasty operations were performed to correct dorsal concave septal deviation between 2005 and 2009 years. The 70 women and 54 men included in the study had an average age of 28 years. The average follow-up period was 12 months. Open septorhinoplasty was preferred in all cases. The medial part of the levator labii alaeque nasi muscle was extensively dissected from the lateral crus and surrounding tissues. The lateral crura of the alar cartilages were separated from the upper lateral cartilages in the scroll area. The dorsal septal deviation was corrected by combination of bilateral spreader grafts, which reinforced cartilage with horizontal control sutures. Early postoperative period was uneventful. Nasal obstruction was reduced after surgery, and significant subjective postoperative improvements were observed in all patients. Comparison of preoperative and postoperative photographs demonstrated improved dorsal nasal contour. Revision operation was performed in 3 cases. The corrected septal cartilage was in a good position in all revised cases; therefore, septal surgery was not performed in the revision operations. In conclusion, surgical disruption of the anatomic relationship between the muscle with the dorsal septal cartilage and reinforcement of the dorsal septal cartilage with spreader grafts and horizontal control sutures can decrease risk of recurrence.

Stress-induced multiple organ damage in rats is ameliorated by the antioxidant and anxiolytic effects of regular exercise.

Our aim was to investigate the effects of moderate load, regular swimming exercise on stress-induced anxiety, and associated oxidative organ injury. Male Sprague-Dawley rats (n = 48) were either kept sedentary or submitted to swimming exercise for 8 weeks. Rats were then divided as non-stressed, acute stress, and chronic stress groups. After acute or chronic stress (electric foot shocks) applications, rats were placed on a holeboard and the exploratory behavior was recorded to assess the anxiety. Rats were decapitated after the stress application. Acute and chronic stress induction led to increased serum cortisol levels as compared to non-stressed groups. Plasma aspartate aminotransferase levels that were elevated in sedentary rats with both stress exposures were lower in trained rats. Malondialdehyde levels and myeloperoxidase activity were increased in the cardiac muscle, liver, stomach, and brain of the stressed rats with a concomitant reduction in the glutathione levels, while stress-induced changes in malondialdehyde, myeloperoxidase, and glutathione levels were reversed in the trained animals. Exercise, which led to increased malondialdehyde and reduced glutathione levels in the skeletal muscle of the non-stressed rats, also protected against stress-induced oxidative damage. Regular exercise with its anxiolytic and antioxidant effects ameliorates stress-induced oxidative organ damage by a neutrophil-dependent mechanism.

Difficulties in diagnosing sexual abuse in children with condyloma acuminata in Turkey.

Human papillomavirus is responsible for anogenital warts and could be regarded as an indicator of possible sexual abuse in children. A genital wart was detected during an investigation of anti-hepatitis C virus positivity in a four-year-old male patient. No pathological findings of another sexually transmitted disease were found except complete cleft palate and circumferential lesions in the perianal region. No family member was anti-hepatitis C virus positive, but the patient's uncle and his wife had genital condylomata. Although detailed physical examination uncovered no other findings indicative of sexual abuse, suspicion of abuse could not be eliminated. Therefore, we wanted to draw the attention of health professionals to the association of anogenital warts and sexual abuse.

Energy expenditure of walking with prostheses: comparison of three amputation levels.

Amputee patients spend more energy during walking than able-bodied persons. It is generally accepted that more proximal amputation is associated with more energy need. However, the picture is not clear, especially for partial foot amputees. The purpose of this study was to compare the energy consumption of walking in traumatic unilateral amputees with three different amputation levels (trans-femoral, trans-tibial and partial foot amputations). Sixty-four male unilateral traumatic amputees participated in this study. Energy expenditure during walking was measured for four different speed and slope combinations: 1.5 km/h and 0 degrees slope, 3 km/h and 0 degrees slope, 1.5 km/h and 5 degrees slope, 3 km/h and 5 degrees slope. Mean O(2) consumption (ml/kg/min) of the last 2 min of each 5-min session was calculated. In all four combinations, energy expenditure of trans-tibial amputees was the lowest, and energy expenditure of trans-femoral amputees was the highest. Statistical significance, however, could not be obtained for the differences among the groups. In conclusion, walking of partial foot amputees does not seem to be more energy efficient than that of higher level amputees.
