Effectiveness of comprehensive rhinoplasty on secondary nasal deformity with saddle nasal deformity after cleft lip surgery / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery.@*METHODS@#The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation.@*RESULTS@#All patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones ( P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied.@*CONCLUSION@#Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.

Reconstrução nasal com uso de costela em paciente com síndrome de Binder: Um relato de caso e revisão de literatura / Nasal reconstruction using ribs in a patient with Binder syndrome: A case report and literature review

Introdução: A síndrome de Binder também pode ser conhecida como displasia maxilonasal e é uma malformação congênita caracterizada por hipoplasia nasomaxilar devido a um subdesenvolvimento do esqueleto facial médio. A atual incidência ou prevalência ainda é desconhecida, mas afeta aproximadamente um recém-nascido vivo em cada 10.000 nascimentos. O diagnóstico pode ser clínico ou associado a ultrassonografia pré-natal, caracterizada por nariz achatado e convexidade anormal da maxila. O tratamento é cirúrgico para correção das anormalidades estéticas e funcionais. Relato de Caso: Paciente que recebeu diagnóstico de síndrome de Binder aos 14 anos, sem outras malformações associadas, com queixa estética e funcional nasal. A correção cirúrgica foi iniciada pela extração de um bloco da sexta cartilagem costal à esquerda, com abertura nasal na margem columelar, no padrão de uma rinoplastia aberta, e dissecados os tecidos no plano subSMAS. Após preparo da área receptora nasal, foram esculpidos bloco de cartilagem para reconstrução do dorso nasal, enxertos alares e enxerto de cartilagem septal. Houve melhora de projeção da ponta nasal e alongamento nasal. Conclusão: A rinoplastia pode ser uma cirurgia desafiadora nesses pacientes, sendo a reconstrução autóloga com o uso de cartilagem costal indicada pela literatura como a melhor opção. É necessário individualizar cada caso para programação de enxertos e reestruturação nasal, sendo fundamental também a melhora funcional desses casos.

Introduction: Binder's syndrome can also be known as maxillonasal dysplasia and it is a congenital malformation characterized by nasomaxillary hypoplasia resulting from an underdevelopment of the middle facial skeleton. The current incidence or prevalence is still unknown, but it affects approximately one child in every 10,000 births. The diagnosis can be clinical or associated with prenatal ultrasonography, characterized by a flattened nose and abnormal maxillary convexity. The treatment is surgical to correct aesthetic and functional abnormalities. Case Report: Patient diagnosed with Binder's syndrome at the age of 14, without other associated malformations, with aesthetic and functional nasal complaints. Surgical correction began with the extraction of a block of the sixth costal cartilage on the left, with a nasal opening on the columellar margin, in the pattern of an open rhinoplasty, and tissue dissection in the sub-SMAS plane. After preparing the nasal receptor area, a block of cartilage was sculpted for reconstruction of the nasal dorsum, alar grafts and septal cartilage grafts. There was an improvement in the projection of the nasal tip and nasal dorsum. Conclusion: Rhinoplasty can be a challenging surgery in these patients, and the literature indicates that the best option is autologous reconstruction with costal cartilage. It is necessary to individualize each case to schedule nasal grafts and restructuring, and functional improvement in these cases is also essential

Effects of costal cartilage cortex on nasal tip contour improvement / 中华医学美学美容杂志

Objective:To investigate the effect of autologous costal cartilage cortex as nasal tip support and modified graft for nasal tip contour improvement.Methods:From June 2020 to June 2021, 116 patients (male 26, female 90, aged 20-45 years) who received rhinoplasty in the cosmetic surgery department of Myoung Beaucare Clinic of Beijing, were examined the costal cartilage by CT, and the costal cartilage was cut. The costal cartilage cortex was made into " strip" and " cap" grafts to shape the nasal tip, and the nasal dorsum was raised by polytetrafluoroethylene or silicone prosthesis for comprehensive rhinoplasty.Results:A total of 116 patients were followed up for an average of 11.7 months. After the operation, there was no space occupying in the nasal cavity, no graft protrusion, no obvious foreign body feeling in the nasal valve, and the nasal tip could swing left and right. At the same time, the nasal tip showed obvious signs, the lower lobule was full, and there were no complications such as cartilage appearance, exposure, infection, etc. Due to the untreated deviation of nasal septum, 3 cases had deviation of nasal columella and asymmetric nostrils. The shape of nasal tip was stable in the remaining 113 cases, and satisfactory results were obtained.Conclusions:By using autologous costal cartilage cortex as nasal tip support and modification graft for nasal tip contour improvement, the shaped nasal tip is soft and movable, and does not affect the airway. It is a good surgical technique in nasal tip plastic surgery, which is worthy of clinical application.

Application of nasal aesthetic polygon theory in reconstruction of new domes by costal cartilage on nasal tip / 中华医学美学美容杂志

Objective:To explore the application of nasal aesthetic polygon theory in the reconstruction of new domes on nasal tip with autogenous costal cartilage.Methods:From June 2019 to June 2021, 116 patients (26 males and 90 females) received rhinoplasty, CT-assisted examination of the costal cartilage, nasal bone and nasal cartilage was performed, and the autogenous costal cartilaginous cortex was used to make dome reconstruction grafts that were transplanted to the original alar cartilage and partially fixed to the original nasal septum cartilage to form a satisfactory and natural nasal shape.Results:All the patients were followed up for 6-24 months. No cartilaginous, overrotated or underrotated appearance was found in nasal tip. The shape of nasal tip was clear and good, with an obvious performance point and full lower lobule. The nose was tall and straight, and looked natural and beautiful in three dimensions.Conclusions:The nasal aesthetic polygon theory is used to guide the reconstruction of new domes with autogenous costal cartilage in nasal tip surgery. Compared to the cap and shield grafts, the nasal tip is more close to the normal anatomical structure, the shape and texture are more similiar to the natural state and the nasal tip is softer by using autogenous costal cartilage, and so it is an ideal surgical procedure for nasal tip reconstruction.

Paranasal augmentation using autologous costal cartilage as an adjunct to rhinoplasty / 中华医学美学美容杂志

Objective:To investigate the postoperative effect of paranasal concavity augment by block united with diced autologous costal cartilage.Methods:The data of 76 patients who were underwent costal cartilage rhinoplasty together with paranasal augmentation from January 2016 to December 2019 were analyzed retrospectively. The surgical technique was described in detail. Medical charts and operative records were reviewed to summary the complications. Patients′subjective satisfaction of the postoperative nasal appearance was self-evaluated with grading (1 worse, 2 no change, 3 improved, and 4 much improved). Cosmetic effects were evaluated by the measurements of the nasolabial angle and the distance between ACJ and intertragic notch preoperatively and postoperatively.Results:The postoperative follow-up duration was 6 to 34 months. Overall, functional and aesthetic outcome was satisfactory in most patients, and the mean score by the patients′self-evaluation was 3.4±0.5. Graft exposure, mobility, or significant resorption, pneumothorax or significant donor-site pain were not observed. The average nasolabial angle was changed from (78.2±13.2)° preoperatively to (89.8±10.2)° 6 months postoperative at the last follow-up ( t=152.00, P<0.01). And the distance from the alar-cheek junction to the left tragus was increased by 3.8±2.1 (2.2-6.1) mm. Conclusions:Costal cartilage rhinoplasty combined with augmentation of parasal area can improve parasal depression, with stable postoperative effect and fewer postoperative complications, and has a good effect for patients with normal occlusal relationship or mild abnormality.

Correção de nariz bífido com técnica tongue-in-groove em paciente com fissura 0-14 de Tessier / Correction of bifid nose with tongue-in-groove technique in patient with Tessier fissure 0-14

Introdução: As anomalias craniofaciais são identificadas usualmente pela sua aparência. Ao longo do tempo, diversas escalas e classificações foram propostas a partir de aspectos clínicos e anatômicos. Em 1976, Tessier fez uma associação entre os tecidos moles e o ósseo subjacente. Com esse conceito, criou um sistema numeral a partir da órbita em sentido horário de 0 - que chamou de linha zero, uma linha vertical da face - a 14. Rara e com múltiplas apresentações, sua condução segue um desafio mesmo para profissionais mais experientes. Relato de Caso: Paciente feminina, submetida a rinoplastia aberta estruturada aos 15 anos de idade para correção de nariz bífido, utilizando cartilagem costal e técnica de tongue-in-groove. Discussão: O nariz bífido é uma das principais apresentações da fissura 0. A rinoplastia aberta estruturada já foi aplicada em outros trabalhos com grande sucesso, sendo a técnica tongue-in-groove especialmente útil para projeção e rotação da ponta nasal. Conclusão: As anomalias craniofaciais variam em suas apresentações e cabe ao cirurgião plástico identificar os problemas e propor soluções terapêuticas que amenizem essas alterações. Seu tratamento irá necessitar de uma avaliação pré-operatória completa, planejamento cirúrgico cuidadoso e técnica cirúrgica meticulosa.

Introduction: Craniofacial anomalies are usually identified by their appearance. Over time, several scales and classifications have been proposed based on clinical and anatomical aspects. In 1976, Tessier made an association between the soft tissues and the underlying bone. With this concept, he created a numeral system from the 0 clockwise orbit - which he called the zero line, a vertical line of the face - to 14. Rare and with multiple presentations, its handling remains a challenge even for more experienced professionals. Case Report: Female patient, submitted to open structured rhinoplasty at 15 years of age for correction of bifid nose, using costal cartilage and tongue-in-groove technique. Discussion: The bifid nose is one of the main presentations of cleft 0. Structured open rhinoplasty has already been applied in other works with great success, being the tonguein- groove technique especially useful for projection and rotation of the nasal tip. Conclusion: Craniofacial anomalies vary in their presentations and it is up to the plastic surgeon to identify the problems and propose therapeutic solutions to alleviate these changes. Treatment will require a thorough preoperative evaluation, careful surgical planning and meticulous surgical technique.

Application of digital technology and three-dimensional silicone cartilage models in auricular reconstruction surgery / 中华医学美学美容杂志

Objective:To establish silicone cartilage models of donor-sites for the microtia patients by using digital technology, and to explore the application of surgical simulation in auricular reconstruction.Methods:From June 2018 to October 2019, 19 congenital microtia patients underwent thoracic CT scans and following three-dimensional costal cartilage imaging with Mimics software at the Nanfang Hospital, Southern Medical University. Among these patients, 16 were males and 3 were females. The mean age of patients was 16 years (range 8 to 35 years). Silicon cartilage models were produced by 3D printing and used for surgical planning and preoperative simulation in ear framework fabrication. Cartilaginous framework was sculptured according to the simulation during operation. Patients were followed up for a minimum of six months to evaluate the size, outline, height and auriculocephalic angle of the reconstructed ear. The satisfactory outcomes of the patients were scored according to a 5-point Likert scale.Results:All the patients received the surgical simulation and sculpture training with silicone cartilage models before operation. Auricular reconstruction was completed successfully according to the simulation. The duration of sculpture was shortened to 1-1.5 hours. There were no serious complications, such as hematoma, inflammation, skin necrosis and framework exposure. The contour of reconstructed ear was natural and clear over a 6 months follow-up, and all the patients were satisfied with their surgical outcomes.Conclusions:With the application of digital technology and silicone cartilage models by 3D printing to the surgical planning and training in microtia patients, patient-specific framework is fabricated with precisely assembling, which not only shortens the operation time, but also provides the unexperienced surgeons with a safe and effective training of ear framework fabrication.

Application of expanded polytetrafluoroethylene combined with autologous costal cartilage in rhinoplasty / 中华医学美学美容杂志

Objective:To investigate the effect of expanded polytetrafluoroethylene (E-PTFE) combined with autologous costal cartilage in rhinoplasty.Methods:Forty-two patients who underwent rhinoplasty in the form of E-PTFE combined with autologous costal cartilage in the Department of Plastic Surgery, Jiangsu Province Hospital of Chinese Medicine from January 2017 to December 2018 were selected as the research object. The polytetrafluoroethylene combined with autologous costal cartilage was used for rhinoplasty. The dorsal nasal skin was dissected through an inverted " V" type combined with subalar cartilage incision, and then the costal cartilage was cut into appropriate cartilage slices to build the nasal tip stent. According to the degree of elevation of the nasal dorsum, the sculpted E-PTFE was placed under the nasal dorsal fascia. The rectus abdominis fascia covered the apex of the nose, and the incision was closed by suture.Results:The nasal appearance of the forty-two patients was significantly improved, with good nasal shape and no serious complications. After 6-12 months of follow-up, 40 cases were satisfacted with the effect of the rhinoplasty, accounting for 95.2%.Conclusions:The use of polytetrafluoroethylene combined with autologous costal cartilage can effectively raise the dorsum of the nose, extend the length of the nose, project the nasal tip in the rhinoplasty. This procedure is accurate and safe, reach a favorable long-term shape and own high satisfaction, and it thus is worthy of popularization in clinic.

OBJECTIVES@#To find the appropriate method for age estimation for different ages and sexes.@*METHODS@#The costal cartilage, sternum and pubic symphysis of 91 unknowns from 2000 to 2020 from the Forensic Department of the Criminal Investigation Team of Shanghai Public Security Bureau were collected. Costal cartilage, sternal and pubic symphysis inferences were used to estimate the age, and the consistency between the estimated results and the actual physiological age of the unknowns was tested. The accuracy of age estimation of different samples was compared, and the relationship between accuracy and age and sex was analyzed.@*RESULTS@#Using the costal cartilage method, the inference errors of males, females and the whole population under 40 years old were (0.608±2.298) years, (0.429±1.867) years and (0.493±2.040) years, while those over 40 years old were (-1.707±3.770) years, (-3.286±4.078) years and (-2.625±4.029) years. The differences between different age groups in these three populations were statistically significant (P<0.05). Using the sternum method, the inference errors of males and females under the age of 40 were (0.921±3.019) years and (0.452±1.451) years, while those over the age of 40 were (-5.903±5.088) years and (-1.429±2.227) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the pubic symphysis method, the inference errors of males and females under 40 years old were (-0.204±1.876) years and (0.238±2.477) years, while those over 40 years old were (1.500±2.156) years and (-2.643±4.270) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the sternum method and pubic symphysis method for age estimation of over 40 years old, the difference between different sexes was statistically significant (P<0.05).@*CONCLUSIONS@#All three methods of age estimation are stable and effective and more accurate for people under 40 years old. For age estimation of unknowns over 40 years old, the pubic symphysis method is preferred in males and the sternum method is preferred in females.

Introducción. La enfermedad de Erdheim Chester es un trastorno infrecuente, de etiología no clara y edad de presentación variable, que se caracteriza por la proliferación anormal de histiocitos no Langerhans. Puede presentarse de forma asintomática, con manifestaciones locales o como complicaciones sistémicas. El diagnóstico se basa en las condiciones clínicas del paciente, estudios imagenológicos y el estudio anatomopatológico, mediante el cual se confirma la enfermedad. Caso clínico. Paciente masculino con una lesión lítica en el séptimo arco costal, inicialmente asintomático y posteriormente con dolor torácico persistente. Se realizó resección y reconstrucción de la pared torácica, con resolución de la sintomatología y adecuada evolución posoperatoria. El resultado de la patología confirmó el diagnóstico de enfermedad de Erdheim Chester. Discusión. Se presenta el caso de un paciente con compromiso costal y fractura patológica como localización y manifestación inusual de la enfermedad de Erdheim Chester, tratado quirúrgicamente de forma adecuada, y sin aparición de recidiva. Debido a la diversidad de síntomas que pueden presentar y a la afectación de múltiples órganos, además de los estudios imagenológicos, la clínica debe orientar los exámenes complementarios, como electro o ecocardiograma, resonancia nuclear magnética, o angioTAC. En los pacientes asintomáticos se ha recomendado un manejo expectante y en los sintomáticos el tratamiento médico con glucocorticoides, inhibidores de BRAF e interferón alfa. El papel de la cirugía no ha sido estudiado a profundidad

Introduction. Erdheim Chester disease is a rare disorder of unclear etiology and variable age of presentation, characterized by abnormal proliferation of non-Langerhans histiocytes. It can present asymptomatic, with local manifestations or as systemic complications. The diagnosis is based on the clinical conditions of the patient, imaging studies, and the pathological study, through which the disease is confirmed.Clinical case. A male patient with a lytic lesion in the seventh costal arch, initially asymptomatic and later with persistent chest pain, underwent resection and reconstruction of the chest wall, with resolution of the symptoms and adequate postoperative evolution. The pathology report confirmed the diagnosis of Erdheim Chester's disease.Discussion. The case of a patient with rib involvement and pathological fracture is presented as an unusual location and manifestation of Erdheim Chester's disease, treated surgically appropriately, and without recurrence. Due to the diversity of symptoms that they can present and the involvement of multiple organs, in addition to imaging studies, the clinic should direct complementary tests such as electrocardiogram or echocardiogram, magnetic resonance imaging, or CT angiography. Expectant management has been recommended in asymptomatic patients, and medical treatment with glucocorticoids, BRAF inhibitors, and interferon alfa in symptomatic patients. The role of surgery has not been studied in depth

Effect of dense dermal fiber structure reconstruction in suprapical region of the nose on correction of nasal hypertrophy / 中华医学美学美容杂志

Objective:To evaluate the clinical effect of remodeling the dense dermal fiber structure in the suprapical region on the correction of nasal hypertrophy.Methods:A retrospective analysis was carried out in beauty-seeking patients who underwent comprehensive costal cartilage rhinoplasty with nasal hypertrophy in our hospital from September 2016 to February 2018. The technique of horizontal scratch reconstruction and deep dermal suture fixation at the tip of the nose was used to fix the dense fibrous dermal fiber structure in the suprapical area. Photos were followed up 12 months after the operation to observe whether the suprapical area had arch and upward displacement of the nasal tip.Results:All patients healed primarily, and the patients were satisfied with the effects. Follow-up results showed that only one female patient showed upshift of nasal tip after surgery among the 57 patients with hypertrophy of nasal tip for beauty. The remaining 56 patients had no upward movement of the nose tip and arching of the upper turning area.Conclusions:By reshaping the dense dermal fiber structure of the suprapical area, the suprapical area of the patients who seek beauty after the operation will have a natural transition, beautiful shape and stable nasal structure.

Efficacy of costal cartilage cortex with retained costal perichondrium on nasal tip reconstruction / 中华医学美学美容杂志

Objective:To evaluate the advantages of cortical perichondrium retention of costal cartilage in tip plasty.Methods:A total of 618 female cases were retrospectively analyzed from July 2017 to July 2018 in Zhengzhou Meilai Medical Beauty Hospital that underwent comprehensive line of rib cartilage rhinoplasty for beauty, aged 18-52 years with mean 27±6 years. According to different modification graft used in plasty, the cases were divided into reserve costal perichondrium cortex group (experimental group) and simple rib cartilage cortex group (control group). Statistical analyses were carried out 1 month and 12 months after operation. The tip displacement visualization was compared between the two groups and the advantages and disadvantages were evaluated in both.Results:After the surgery of the 618 patients, the rate of displacement in the experimental group was 3.6%, and that in the control group was 7.9% (χ 2=4.95, P<0.05). The rate of the implant exposure in the experimental group was 4.7%, and that in the control group was 9.1% (χ 2=4.38, P<0.05). The reserve costal perichondrium cortex used in the nasoplasty kept the prominent and stable nasal tip after the operation, and longterm follow-up showed there were no displacement and deformation occured in the patients. Conclusions:The application of costal cartilaginous cortex retaining costal perichondrium in tip plasty can obtain good nasal tip protrusion and stable rotation. It is an ideal nasal tip shaping material and worthy of clinical application.

Angiographic anatomy of lateral costal artery and its clinical significance / 中国医师杂志

Objective:To study the angiographic anatomy of the lateral costal artery (LCA) and its effect on hemoptysis.Methods:The CT data of angiography and angiographic-CT in 303 patients with hemoptysis in Guangzhou First People′s Hospital were analyzed retrospectively. The origin and travel of the lateral costal artery and the blood supply of the LCA involved in the pulmonary lesion were analyzed.Results:In 303 patients with hemoptysis, 30 LCA were detected in 24 cases, including 12 on the left and 18 on the right, 18 on one side and 6 on both sides. All of them were the first branch of the first segment of the internal thoracic artery (ITA). The level of LCA originating from ITA was located in 1(3.3%) branch above clavicle, 27(90.0%) branches behind clavicle and 2(6.7%) branches below clavicle. LCA entered into the chest behind the first anterior rib, and walked along inner surface of the thorax from the anterior and superior direction to the outer and posterior direction, between the rib-intercostal medial muscle and pleura (i.e., anatomical intrathoracic fascia), and mostly terminated at the axillary midline plane. 28 LCA in 23 patients which can be used for morphological analysis, roughly manifested as follow three shapes: ⑴ 13(46.4%) of them were arc-shaped. The developed LCA was longer and showed shallow or deep arc-shaped curve; ⑵ High flat shape, total 11 LCA (39.3%), the LCA were relatively shorter, position higher and more gentle; ⑶ 4(14.3%) were straight and oblique. The developed LCA was relatively long, and the angle between LCA and ITA was linear. 11 vessels (36.67%) of 10 patients participated in the blood supply of pulmonary lesions, among which 2, 5, 1, 2 and 1 vessels were responsible for the first, second, third, fourth and fifth hemoptysis respectively.Conclusions:The LCA is a relatively common blood vessel and it can be well shown by angiography and angiographic CT. It is of great clinical significance to understand LCA.

Manejo actualizado de las fracturas costales / Current management of rib fractures

RESUMEN Las fracturas costales son la lesión más frecuente en los traumatismos torácicos. La fijación de las fracturas ha estado dirigida clásicamente al volet costal. En los últimos años se han extendido las indi caciones a las fracturas múltiples desplazadas aun sin volet. Se consideran asimismo otras indicaciones de osteosíntesis menos frecuentes. La neumonía y contusión pulmonar graves que requieren asisten cia respiratoria mecánica son consideradas contraindicaciones para la fijación quirúrgica. La primera semana es el momento óptimo para su realización. Diversos dispositivos de fijación se han ideado; las placas de titanio son las más utilizadas. La osteosíntesis costal ofrece a los pacientes una recuperación más rápida con menor estadía hospitalaria y en cuidados críticos, así como mejor funcionalidad respi ratoria y menor dolor en el corto y largo plazo.

ABSTRACT Rib fractures are the most common injuries in chest trauma. Fracture fixation has been traditionally performed in flail chest patients. Over the past years, the indication has been extended to multiple, severely displaced non-flail pattern fractures. Other less common indications for osteosynthesis have also been considered. Severe pneumonia and lung contusion requiring mechanical ventilation are considered contraindication for surgical fixation. The optimal timing for the intervention is the first week. Several devices have been developed for fracture fixation; titanium plates are the most commonly used. Rib fixation offers patients a more rapid recovery with shorter length of hospital stay and of intensive care unit stay with improved respiratory function and pain management in the short and long term.

Comparison of Serum Biochemical and Mineral Profiles of Cattle Reared Under Island and Coastal Ecosystem

The present study was conducted in the Department of Animal Reproduction Gynaecology and Obstetrics, College of Veterinary Science and Animal Husbandry, OUAT, BBSR in collaboration with ICAR-Central Island Agricultural Research Institute, Portblair (Andaman and Nicobar Island). Crossbred cattle with the history of anoestrus and repeat breeding were considered for the present investigation. The basic difference in serum biochemical and mineral profiles of cattle reared under two quite different ecosystems namely Island and coastal ecosystem was estimated which might be due to the variability in rainfall, ambient temperature, day light length and humidity. The incidence of different infertility conditions in both the ecosystems also might vary as per the environment. Serum samples were collected for estimations of biochemical parameters like total protein, glucose, cholesterol, Ca, P and Ca:P ratio. The overall incidence of infertility was recorded to be 47.62 % in island and 45.90 % in coastal ecosystem. No significant difference in serum levels of total protein, glucose, cholesterol, zinc, copper and manganese could be observed in between cattle reared in both ecosystems. It was concluded that the variations in humidity, ambient temperature, rain fall and day light length between Portblair, Andaman and coastal climate of Odisha, did not have much effect on reproduction of cattle

Uso de fáscia peitoral maior em preenchimento de dorso nasal: relato de caso / Use of pectoralis major fascia in dorsal nasal augmentation: case report

O aumento do dorso nasal nas rinoplastias é foco de estudo de diversos trabalhos que buscam as melhores fontes de enxerto e técnicas cirúrgicas. A utilização de cartilagem já é consagrada para este fim, a partir do septo nasal, da concha auricular ou dos arcos costais. Nos últimos anos, têm-se buscado meios para reduzir a palpabilidade e dispersibilidade dos enxertos cartilaginosos. Assim, são descritos materiais sintéticos, como o SURGICEL®; e, autólogos, representados pelas fáscias. A fáscia temporal é mais amplamente utilizada, porém requer uma nova incisão cirúrgica, aumentando o tempo e a morbidade da cirurgia. É também descrito o uso de fáscia lata e fáscia reto abdominal, comparativamente mais espessas e menos flexíveis. Em muitos casos de rinoplastia fazse necessária a retirada da cartilagem costal, o que permite a coleta de fáscia do músculo peitoral maior pela mesma incisão cirúrgica. Dessa forma, descrevemos a utilização da fáscia do músculo peitoral maior envolvendo cartilagem costal picada, em uma rinoplastia estruturada com aumento do dorso.

Increasing the nasal dorsum in rhinoplasty is the focus of several studies that seek the best graft sources and surgical techniques. The use of cartilage from the nasal septum, ear shell, or costal arches is already established for this purpose. In recent years, methods have been sought to reduce the palpability and dispersibility of cartilaginous grafts. Thus, synthetic materials such as SURGICEL® and autologous materials such as fascia have been explored. Temporal fascia are more widely used but require a new surgical incision, increasing surgical time and morbidity. Also described is the use of fascia lata and rectus abdominis fascia, which are comparatively thicker and less flexible. In many rhinoplasty procedures, it is necessary to remove the costal cartilage, which allows the collection of fascia from the major chest muscles through the same surgical incision. Thus, we describe the use of major chest muscle fascia and chopped costal cartilage in structured rhinoplasty to increase the dorsum.

Split cricoídeo posterior endoscópico con injerto de cartílago costal / Endoscopic posterior cricoid split with costal cartilage graft

RESUMEN A pesar de los avances en cirugía de vía aérea, tanto abierta como endoscópica, la inmovilidad bilateral de cuerdas vocales continúa representando un desafio significativo para los cirujanos de vía aérea. Entre las alternativas quirúrgicas existen tanto abordajes endoscópicos como transcervicales, no obstante, la mayoría de estas técnicas modifican estructuralmente regiones de la cuerda vocal y/o aritenoides de manera permanente. La traqueostomía ha sido el tratamiento de elección en niños con inmovilidad bilateral de cuerdas vocales severamente sintomática, sin embargo, el procedimiento ideal debiese establecer una vía aérea adecuada evitando la necesidad de realizar una traqueostomía, y a la vez no generar un deterioro de la función fonatoria. La capacidad de expandir el aspecto glótico posterior sin modificación estructural de aritenoides y/o ligamento vocal ha convertido a la sección cricoidea posterior endoscópica con injerto de cartílago costal en una alternativa quirúrgica atractiva para estos casos. En este trabajo se realiza una revisión de la literatura y presenta un caso tratado mediante esta técnica en el Hospital Guillermo Grant Benavente de Concepción, Chile.

ABSTRACT Despite advances in both open and endoscopic airway surgery, bilateral vocal cord immobility still poses a significant challenge for airway surgeons. Among the surgical alternatives there are both endoscopic and transcervical approaches. However, most of these techniques structurally modify certain regions of the vocal cord and/or arytenoids permanently. Tracheostomy has been the treatment of choice in severely symptomatic children with bilateral immobility of vocal cords. Nevertheless, the ideal procedure should establish an adequate airway, avoiding the need to perform a tracheostomy, and at the same time not causing a deterioration of the phonatory function. The ability to expand the posterior glottis without structural modification of the arytenoids and/or vocal ligament has converted the posterior endoscopic cricoid split with costal cartilage graft into an attractive surgical alternative for these cases. In this article we review the literature and present a case treated by this technique in the Guillermo Grant Benavente Hospital in Concepción, Chile.
