ABSTRACT

OBJECTIVE@#To provide an overview of the incidence of knee donor -site morbidity after autologous osteochondral mosaicplasty.@*METHODS@#A comprehensive search was conducted in PubMed, EMbase, Wanfang Medical Network, and CNKI databases from January 2010 to April 20, 2021. Relevant literature was selected based on predefined inclusion and exclusion criteria, and data were evaluated and extracted. The correlation between the number and size of transplanted osteochondral columns and donor-site morbidity was analyzed.@*RESULTS@#A total of 13 literatures were included, comprising a total of 661 patients. Statistical analysis revealed an incidence of knee donor-site morbidity at 8.6% (57/661), with knee pain being the most common complaint, accounting for 4.2%(28/661). There was no significant correlation between the number of osteochondral columns and postoperative donor-site incidence (P=0.424, N=10), nor between the diameter size of osteochondral columns and postoperative donor-site incidence(P=0.699, N=7).@*CONCLUSION@#Autologous osteochondral mosaicplasty is associated with a considerable incidence of knee donor-site morbidity, with knee pain being the most frequent complaint. There is no apparent correlation between donor-site incidence and the number and size of transplanted osteochondral columns. Donors should be informed about the potential risks.

ABSTRACT

Abstract Introduction Various graft materials have been used in the tympanoplasty technique. Cartilage grafts are being used increasingly in recent years. Objective The aim of this study was to present the comparative outcomes of the perichondrium-preserved palisade island graft technique previously defined by ourselves. Methods We retrospectively compared the hearing and graft success rates in 108 patients with chronic otitis media, who had undergone cartilage tympanoplasty, where both island and perichondrium-preserved palisade graft techniques were used. Results The success rates among the study and the control groups with regard to graft take were 97% and 93%, respectively. No significant difference was observed between the groups with regard to the postoperative mean pure tone values, improvement in air-bone gaps and reduction in air-bone gaps to under 20 dB. However, better results were observed in the study group. Conclusion The perichondrium-preserved palisade island graft technique is an easy method with high graft success rates and hearing outcomes.


Resumo Introdução Vários materiais de enxerto têm sido usados na realização de timpanoplastias. Nos últimos anos, os enxertos de cartilagem têm sido cada vez mais usados. Objetivo Apresentar os resultados comparativos da técnica de enxerto de cartilagem em ilha associada e paliçada preservado em pericôndrio previamente descrita pelos autores. Método Foram comparadas retrospectivamente as taxas de sucesso auditivo e na "pega" do enxerto em 108 pacientes com otite média crônica, submetidos a timpanoplastia com cartilagem, na qual foram usadas ambas as técnicas, de enxerto em ilha e paliçada preservado em pericôndrio. Resultados As taxas de sucesso entre os grupos de estudo e controle em relação à "pega" do enxerto foram de 97% e 93%, respectivamente. Não foi observada diferença significante entre os grupos em relação aos valores médios dos tons puros, melhoria do gap ou redução do aéreo-ósseo para menos de 20 dB no pós-operatório. No entanto, melhores resultados foram observados no grupo de estudo. Conclusão A técnica de enxerto em ilha associada e paliçada preservado em pericôndrio é um métodofácil, com altas taxas de sucesso tanto do enxerto quanto dos resultados auditivos.

ABSTRACT

Resumo Introdução: O enxerto de extensão caudal é geralmente um enxerto de cartilagem que se sobrepõe à margem caudal do septo nasal. Uma combinação do enxerto de extensão caudal e a técnica de tongue-in-groove é usada para estabilizar a base nasal, definir a projeção da ponta e refinar a relação alar-columelar. Objetivo: Apresentar algumas novas modificações na colocação dos enxertos de extensão caudal na rinoplastia. Método: Revisão retrospectiva de um banco de dados prospectivamente coletado de 965 pacientes que se submeteram a rinosseptoplastia de junho de 2011 a julho de 2015. Desses, 457 pacientes necessitaram de enxerto de extensão caudal e foram incluídos no estudo. O seguimento mínimo foi de 13,2 meses, com tempo médio de seguimento de 17,4 meses. Resultados: Na maioria dos casos, a comparação das fotografias antes e após a cirurgia foi satisfatória e apresentou melhora do contorno. Pequenas deformidades foram detectadas em 41 pacientes e 11 pacientes necessitaram de cirurgia de revisão. Conclusão: Com essas modificações, o cirurgião pode usar o enxerto de extensão caudal mesmo em desvios angulares do septo caudal. Vários métodos têm sido propostos para correção do desvio septo-caudal.

ABSTRACT

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.

ABSTRACT

Abstract Introduction Different types of autologous graft materials are used for myringoplasty, with the temporalis fascia and cartilage being the most frequently used tissues. Periosteal tissue has been used for a long time in our department, and many advantages support its use in myringoplasty. To the best of our knowledge, this issue is scarcely discussed in the previously published literature. Objective To present our experience with periosteal graft myringoplasty, describing the technique and the anatomical and functional outcomes. Methods A prospective clinical study involving 88 patients (72 females and 16 males) with a mean age 26.9 years. The patients underwent myringoplasty using the mastoid cortex periosteum; they were all operated using the postauricular approach, and the graft was applied using the underlay technique. The patients performed pre- and postoperative pure tone audiometry for tested frequencies (0.5 kHz, 1 kHz, 2 kHz, and 4 kHz). All patients were followed-up for at least 12 months after the operation. Results The anatomical success rate among all patients was of 93%, which is comparable to the rate of success in procedures using other usual grafting materials. In addition, there was a highly significant postoperative improvement in pure tone audiometry results as compared with the preoperative ones (the main hearing gain was of ∼ 11 dB; p< 0.001). Conclusion The periosteal graft is easily harvested, easy to apply, with excellent anatomical and functional success.

ABSTRACT

RESUMEN Introducción: Entre las alteraciones del dorso nasal puede encontrarse desde un rádix bajo hasta un aplastamiento severo del dorso nasal, siendo fundamental el uso de injertos y material de relleno. Objetivo: Proponer una nueva alternativa de relleno y camuflaje en rinoplastía mediante un injerto mixto de L-PRF más cartílago picado en una matriz de fibrina autóloga. Material y método: Evaluación de los pacientes operados de rinoseptoplastía en quienes se utilizó el injerto mixto entre febrero y septiembre del año 2016 en el Servicio de Otorrinolaringología del Hospital Regional de Concepción. Evaluación de resultados respecto a reabsorción e irregularidades del injerto y autoevaluación del grado de satisfacción. Resultados: Fueron operados 7 pacientes. Cuatro de ellos presentaban aplastamiento severo de dorso nasal y tres un rádix profundo. Se logró el relleno y camuflaje del área deseada en todos los casos. No se presentó desplazamiento ni reabsorción del injerto en ninguno de los casos. El uso de este injerto no significó mayor costo económico, y el grado de satisfacción fue alto en todos los casos. Conclusión: Primer estudio en utilizar un injerto mixto de cartílago más L-PRF en una matriz de fibrina autóloga en rinoplastía, demostrando ser una alternativa asequible, efectiva, reproducible y segura, particularmente útil en casos de revisión.


ABSTRACT Introduction: Among the alterations of the nasal dorsum there can be found from a low radix to a severe crushing of the nasal dorsum, being fundamental the use of grafts and filling materials. Aim: To propose a new filling and camouflage alternative in rhinoplasty by means of a mixed graft of L-PRF and chopped cartilage in an autologous fibrin matrix. Material and method: Evaluation of the operated patients of rhinoseptoplasty in whom the mixed graft was used between February and September 2016 in the Otorhinolaryngology unit of the Hospital Regional de Concepción. Evaluation of results regarding resorption and graft irregularities and self-assessment of degree of satisfaction. Results: Seven patients were operated. Four of them presented severe crushing of the nasal dorsum and three of them a deep radix. The filling and camouflage of desired area was achieved in all cases. There were no displacement or resorption of the graft in any case. The use of this graft did not mean greater economic cost, and the degree of satisfaction was high in all cases. Conclusions: First study to use a mixed graft of cartilage and L-PRF in an autologous fibrin matrix in rhinoplasty, proving to be an affordable, effective, reproducible and safe alternative, particularly useful in revision surgeries.

ABSTRACT

Abstract Introduction: Same-day closure of bilateral tympanic membrane perforations is a quick and more comfortable procedure for the patients. However, conventional bilateral same-day tympanoplasty or myringoplasty has been rarely performed because of the theoretical risk of postoperative complications. Objective: To evaluate the advantages and outcomes of bilateral simultaneous endoscopic cartilage tympanoplasty in patients with bilateral tympanic membrane perforations. Methods: From February 2012 to March 2013, patients with bilateral dry tympanic membrane perforations who had some degree of hearing loss corresponding to the size and location of the perforation entered the study. There was no suspicion to disrupted ossicular chain, mastoid involvement or other middle or inner ear pathology. Endoscopic transcanal cartilage tympanoplasty was done using the underlay (medial) technique. The graft was harvested from cymba cartilage in just one ear with preservation of perichondrium in one side. A 1.5 cm × 1.5 cm cartilage seemed to be enough for tympanoplasty in both sides. Results: Nine patients (4 males and 5 females) with the mean age of 37.9 years underwent bilateral transcanal cartilage tympanoplasty in a same-day surgery. The mean duration of follow up was 15.8 months. There were detected no complications including hearing loss, otorrhea and wound complication with no retraction pocket or displaced graft during follow-up period. The grafts take rate was 94.44% (only one case of unilateral incomplete closure). The mean of air-bone gap overall improved from 13.88 dB preoperatively to 9.16 dB postoperatively (p < 0.05). Conclusion: Bilateral endoscopic transcanal cartilage tympanoplasty can be considered as a safe minimally invasive procedure that can be performed in a same-day surgery. It reduces the costs and operation time and is practical with a low rate of postoperative complications.


Resumo Introdução: O fechamento no mesmo dia de perfuração bilateral da membrana timpânica é um procedimento rápido e mais confortável para os pacientes. Entretanto, a timpanoplastia ou miringoplastia convencional bilateral executada no mesmo procedimento tem sido raramente feita devido ao risco teórico de complicações pós-operatórias. Objetivo: Avaliar as vantagens e os resultados da timpanoplastia bilateral simultânea com cartilagem por via endoscópica em pacientes com perfuração bilateral da membrana timpânica. Método: De fevereiro de 2012 a março de 2013, pacientes com perfuração seca bilateral da membrana timpânica que tinham algum grau de perda de audição correspondente ao tamanho e à localização da perfuração foram incluídos no estudo. Não houve suspeita de cadeia ossicular interrompida, envolvimento do mastoide ou outra doença da orelha média ou interna. Timpanoplastia com cartilagem transcanal foi executada por via endoscópica com a técnica de underlay (medial). O enxerto foi colhido de cartilagem da concha superior (cymba) em apenas uma orelha com preservação do pericôndrio em um lado. Um enxerto de 1,5 × 1,5 centímetro de cartilagem pareceu ser o suficiente para a timpanoplastia em ambos os lados. Resultados: Nove pacientes (quatro homens e cinco mulheres) com média de 37,9 anos foram submetidos à timpanoplastia bilateral com cartilagem transcanal em uma cirurgia feita em etapa única. O tempo médio de acompanhamento foi de 15,8 meses. Não foram detectadas complicações, inclusive perda de audição, otorreia e complicações como bolsa de retração ou deslocamento de enxerto durante o período de seguimento. A taxa de sucesso do enxerto foi de 94,44% (apenas um caso de fechamento unilateral incompleto). A média do gap aéreo-ósseo em geral melhorou de 13,88 dB no pré-operatório para 9,16 dB no pós-operatório (p < 0,05). Conclusão: Timpanoplastia bilateral com cartilagem transcanal por via endoscópica pode ser considerada como um procedimento minimamente invasivo, seguro e que pode ser executado em uma única cirurgia. Isso reduz os custos e tempo de operação e é prático, com um baixo índice de complicações pós-operatórias.

ABSTRACT

El condroblastoma de la cabeza femoral es un tumor poco frecuente (aproximadamente 1 o 2% de los tumores benignos de hueso), se presenta con mayor frecuencia en pacientes jóvenes de sexo masculino. El condroblastoma es más frecuente en el húmero proximal, fémur proximal, fémur distal y tibia proximal. La cabeza femoral es el tercer sitio más frecuente, No existe un tratamiento específico para esta entidad; se han descrito desde osteotomías acetabulares, injertos osteocondrales, injertos vascularizados de peroné, etcétera, todos reportando buenos resultados. Pero es clínicamente impredecible si no recibe tratamiento. Se presenta un caso que se manejó con aloinjerto osteocondral y la evolución de tres años posterior al procedimiento quirúrgico...


Femoral head chondroblastoma is an infrequent tumor, accounting for approximately 1-2% of benign bone tumors. It occurs more frequently in young male patients. It's most frequent locations include the proximal humerus, proximal femur, distal femur and proximal tibia. The femoral head is the third most frequent site of this tumor. There is no specific treatment for this entity; reported treatments range from acetabular osteotomies and osteochondral grafts, to vascularized fibular grafts, all of them with good results. However, this tumor is clinically unpredictable if left untreated. We report a case managed with osteochondral graft and followed-up for three years after the surgical procedure...

ABSTRACT

Introduction: Cartilage graft tympanoplasty has a better success rate in the treatment of chronic otitis media if regularly prepared and placed. Objective: To prepare cartilage island material and evaluate its effect on the success rate of tympanoplasty. Methods: The medical records of 87 patients (48 males and 39 females; mean age, 27.3 ±11.2 years; range, 14–43 years) with chronic otitis media without cholesteatoma who underwent intact canal-wall-up tympanoplasty and revision surgery between December of 2007 and October of 2011 were retrospectively evaluated. Surgery was performed under general anesthesia via a retroauricular approach. Results: The overall success rate of this technique was 93% in terms of perforation closure. No graft lateralization or displacement into the middle ear occurred. The overall average preoperative air bone gap was 37.27 ± 12.35 dB, and the postoperative air bone gap was 27.58 ± 9.84 dB. The mean postoperative follow-up period was 15.3 months (range: 7–21 months). Conclusion: If cartilage graft is properly prepared and placed, cartilage graft tympanoplasty appears to provide better success rates and hearing results. .

ABSTRACT

Las lesiones osteocondrales en la rodilla representan un problema frecuente en la práctica médica. Estas llevan a la degeneración del cartílago hialino con la consecuente artrosis, causa importante de dolor y discapacidad. En los últimos años se han desarrollado múltiples técnicas para tratar estas lesiones. El sistema de transferencia osteocondral autólogo (OATS) ha sido descrito para el tratamiento de estos defectos focales en los cóndilos femorales; sin embargo, su aplicación real en la patela es todavía un tema de controversia. Una correcta selección de los pacientes en conjunto con una técnica quirúrgica adecuada son fundamentales para el resultado exitoso de esta cirugía. Nuestro objetivo es describir la técnica quirúrgica y los aspectos involucrados en el sistema de transferencia osteocondral autólogo para lesiones condrales focales de la patela.


Osteochondral injuries in the knee are a common problem in medical practice. These lead to the degeneration of the hyaline cartilage and the consequent osteoarthritis, a major cause of pain and disability. In recent years several techniques have been developed to treat these injuries. The osteochondral autologous transfer system (OATS) has been described for the treatment of these defects on the femoral condyles, however its actual implementation in the patella is not yet clear. Patient selection and adequate surgical technique are fundamental to a successful surgery. Our objective is to describe the surgical technique and aspects involved in the osteochondral autograft transfer system for isolated chondral injuries of the patella.

ABSTRACT

Numerous graft materials and methods of placement have been described to reconstruct the tympanic membrane. Cartilage was shown both experimentally and clinically to be well tolerated by the middle ear and has long-term survival. A twelve-year-old female presented with history of recurrent episodes of right ear pain and discharge. She experienced slight hearing impairment in the right ear. On examination, she was found to have perforation in antero-inferior quadrant of tympanic membrane of the right ear which was operated successfully with a new technique utilizing a composite 3 layers graft [Perichondrium-Cartilage-Perichondrium] via transcanal approach.

ABSTRACT

Introducción: Un dorso recto es uno de los principales objetivos para los pacientes que se realizan una rinoseptoplastía. Sin embargo, una resección dorsal excesiva puede traer consecuencias estéticas y funcionales. Objetivos: Describir la experiencia del Departamento de Otorrinolaringología del Hospital Clínico de la Pontificia Universidad Católica de Chile en el manejo del dorso nasal. Material y método: Estudio retrospectivo descriptivo. Se revisaron los protocolos quirúrgicos de los pacientes sometidos a una rinoseptoplastía entre enero de 2010 y junio de 2011. Resultados: Se recopiló un total de 153 pacientes, 67% mujeres. La edad promedio fue de 27,5 años. El abordaje fue abierto en el 78%%. Más del 95%% requirió resección dorsal osteocartilaginosa y osteotomías. El injerto espaciador fue el injerto dorsal más frecuente (51%%). En 101 mujeres y 47 hombres se realizó trabajo de punta nasal (p <0,05). Discusión: En nuestra experiencia el abordaje abierto nos permite obtener una visión más clara de la anatomía. La septoplastía, importante en el manejo de la obstrucción nasal, nos permite además obtener injertos de buena calidad. En pacientes de riesgo de colapso valvular, es importante una resección dorsal conservadora y considerar los injertos espaciadores.


Introduction: A right dorsum is one of the main objectives for patients who undergoes to rhinoseptoplasty. However, excessive dorsal resection can bring aesthetic and functional consequences. Aim: To describe the experience in the management of the nasal dorsum by the Hospital Clínico de la Pontificia Universidad Católica de Chile, ENT Department. Material and method: Retrospective study. All patient's surgical protocols of rhinoseptoplasty between January 2010 and June 2011 were reviewed. Results: 153 patients were collected, 67%% of them were women. The average age was 27.5 years. The open approach was performed in 78%%. Over 95%% of patients required dorsal osteocartilaginous resection and osteotomies. The spreader graft was the most commonly used dorsal graft (51%%). In 101 women and 47 men, nasal tip work were performed (p <0.05). Discussion: In our experience the open approach allows us to obtain a clear vision of the nasal anatomy. Septoplasty is important in the management of the nasal obstruction, and it permits to obtain good quality grafts. In patients at risk of valvular collapse is important a conservative dorsal resection and spreader grafts.

ABSTRACT

OBJECTIVE: To evaluate the clinical and functional results of autologous trapezoidal plug single-block grafts fixed with absorbable chondral darts in patients with osteochondral knee lesions of varying sizes. METHODS: Twenty-five patients underwent surgery from February 2000 to June 2008. Seventy-two percent of the patients were male, and the mean age was 29 years. RESULTS: The right side (56%) and the medial condyle (92%) were most affected. The lesions had an average area of 5.28 cm², and the mean follow-up was 59 months. All of the variables other than instability showed significant improvements (p<0.05), as shown by the increase in the mean Lysholm score from 55 points preoperatively to 92 points (p<0.001) postoperatively. There was no loosening or collapse of the osteochondral graft. All of the patients had patellofemoral crepitation and pain for an average of six months. CONCLUSION: Autologous trapezoidal plug single-block grafts are a therapeutic option for defects of varying sizes and provide good clinical results and low morbidity at the donor site in the medium term.

ABSTRACT

Introdução: A rinoplastia é considerada um dos procedimentos mais desafiadores da cirurgia plástica. Diante disso, diversas técnicas foram desenvolvidas com o objetivo de alcançar resultados mais naturais e previsíveis. Essas técnicas foram criadas a partir do princípio básico de que a manutenção das estruturas de suporte do nariz é fundamental para o tratamento estético e funcional durante a rinoplastia. Método: Os autores apresentam uma série de doze pacientes operados entre janeiro de 2008 e março de 2009, submetidos à rinoplastia para correções de deformidades estéticas e funcionais. Durante os procedimentos, foram utilizados enxertos autólogos de cartilagens do septo, concha auricular e costela. Resultados: Os enxertos mais utilizados foram os strut grafts (100%), spreader grafts (92%), alar contour grafts (58%) e lateral crural strut grafts (33%). Não houve sofrimento ou cicatrizes patológicas nos casos operados. Entre as complicações nas áreas doadoras, foram observados: um caso de hematoma em orelha, um caso de cicatriz hipertrófica em tórax e dois casos de pústulas em mucosa septal. O resultado estético foi satisfatório para os pacientes em 92% dos casos enquanto, do ponto de vista funcional, em 58% dos casos, houve melhora na qualidade da respiração e, em 42%, a função se manteve inalterada. Conclusão: A utilização de enxertos autógenos de cartilagem se mostrou efetiva no tratamento das deformidades estéticas e funcionais, proporcionando suporte adequado ao esqueleto osteocartilaginoso e às válvulas internas e externas nasais, com índice de complicações aceitáveis e pequena morbidade das áreas doadoras.


Introduction: Rhinoplasty is considered one of the most challenging procedures in the plastic surgery. Therefore, several techniques were developed to reach more natural and predictable results. These techniques were created from basic principles, which the adequate maintenance of the nose structures is essential for the aesthetic and functional treatment during rhinoplasty. Methods: The authors presents twelve patients that were operated between January of 2008, and March of 2009. They all were submitted to rhinoplasty for aesthetic and functional deformities corrections. During the procedures there were used autologous grafts from septal cartilage, auricular shell and rib, according to the criteria presented by the author. Results: The most used grafts were the strut grafts(100%), spreader grafts (92%), alar contour grafts (58%) and lateral crural strut grafts (33%). There were no suffering or pathological scars on the operated cases. Among the complications in the donated areas, were a case of hematoma in the ear, a case of hypertrophic scar in thorax, and two cases of pustules on septal mucous membrane. The aesthetic result was satisfactory for the patients in 92% of the cases, while from the functional point of view, in 58% of the cases there was an improvement in the breathing quality, and in 42% the function remained unchanged. Conclusion: The use of autologous cartilage grafts demonstrated effectiveness in the aesthetic and functional deformities treatment, providing appropriate support to the osseocartilaginous skeleton and to the internal and external nasal valves, with acceptable complications rate and little morbidity on donated areas.

ABSTRACT

La estenosis de la válvula nasal aparece como una complicación frecuente de rinoplastfa o traumatismo nasal. Existen diferentes técnicas para corregir el colapso de la válvula nasal; generalmente se utilizan injertos de tejido, que en algunas ocasiones son insuficientes para resolverla alteración y mejorar la función respiratoria. La válvula nasal funciona en base a la resistencia de la ley Starling, que consiste en un tubo semirrígido con un segmento flexible; cuando la presión inspirada excede un nivel crítico, éste se colapsa y provoca la alteración en su fisiología; por tanto, es necesario cierto grado de rigidez en el componente lateral nasal para evitar el colapso durante la inspiración. Cuando se ve afectado su funcionamiento causa frecuentemente obstrucción nasal.


Nasal valve stenosis commonly presents as a postoperative complication of rhinoplasty or facial trauma. Various techniques have been reported to correct nasal valve stenosis through the use of methods that support the nasal valve with cartilage, rib graft, although these tissues are not useful in some cases to improve the nasal breathing. The nasal valve functions as the law Starling resistor, which is a semirigid tube with a flexible segment, when the inspired partial pressure exceeds a critical level, it collapses and causes nasal obstruction, and therefore need some degree of rigidity in nasal lateral component to avoid collapse during inspiration. When the nasal valve is affected frequently causes nasal obstruction.

ABSTRACT

Vários materiais são propostos para reconstrução nasal, não havendo consenso sobre qual o melhor. A manta de celulose produzida por bactéria pode ser mais um elemento para adição cartilaginosa. Não há estudos deste material no dorso nasal. OBJETIVO: Avaliar a resposta tecidual à presença da celulose bacteriana no dorso nasal de coelhos. MATERIAL E MÉTODO: Foram utilizados 22 coelhos Nova Zelândia, sendo que em 20 deles foi implantada a manta de celulose no dorso nasal e em 2 controles nada foi feito. Foram acompanhados por um período de três e seis meses, sendo então retirados as regiões do dorso nasal e narinas dos coelhos e realizado estudo histopatológico levando em consideração parâmetros definidos de condição inflamatória como congestão vascular, intensidade do processo inflamatório e presença de exsudato purulento. RESULTADOS: O processo inflamatório manteve-se estável, demonstrando sua relação com o procedimento cirúrgico, e não com a presença da manta de celulose. Nos demais parâmetros estudados não houve diferença estatisticamente significante. CONCLUSÃO: A manta de celulose de Acetobacter xylinum mostrou boa biocompatibilidade e manteve-se estável no decorrer do tempo de estudo, podendo ser considerada um bom material para uso na elevação do dorso nasal.


Several materials have been proposed for nasal reconstruction. There is no consensus on which is the best. The cellulose blanket produced by bacteria may be a possible cartilaginous addition element to the nose. AIM: to study tissue reaction to cellulose in the dorsal nose of rabbits. MATERIALS AND METHODS: 22 New Zealand rabbits were used. In 20 a cellulose blanket was implanted in the nasal dorsum and 2 served as controls. They were followed up through a period of three and six months, after which their nostrils and nasal dorsums were removed and histological studies were carried out on them, considering defined parameters of inflammation such as vascular congestion, intensity of the inflammatory process and presence of purulent exudate. RESULTS: The inflammatory process remained stable, showing its relationship with the surgical procedure and not with the presence of the cellulose blanket. There were no statistical differences in the other parameters. CONCLUSION: The cellulose blanket produced by Acetobacter xylinum presented good biocompatibility, remained stable during the entire study period, and could be considered a good material for elevating the nasal dorsum.

ABSTRACT

La rotación y la proyección de la punta nasal representan dos de los parámetros más importantes a ser tomados en cuenta durante la rinoseptoplastia. Nos permite establecer un complejo de punta nasal cercano a lo considerado estéticamente ideal y además establece directrices acerca del manejo del dorso nasal. En el siguiente trabajo expones nuestra experiencia con el uso de injerto cartilaginoso antólogo, utilizando como extensor del borde caudal del septum nasal, como método para mejorar la rotación y proyección de la punta nasal en casos seleccionados. Se realizó un estudio prospectivo de un grupo seleccionado de 37 pacientes entre el año 2003 y el año 2007, con criterios para la realización de dicha técnica quirúrgica, esta es descrita de manera sistemática. En el 95 por ciento de los casos se obtuvieron resultados satisfactorios. Se discuten las ventajas y desventajas de la técnica quirúrgica
