Outcomes in breast reconstruction using the BREAST-Q questionnaire at a third level hospital center in Mexico City

Background: Breast reconstruction can have a significant impact on the physical, emotional and psychological well-being of patients undergoing mastectomy. The type and timing of breast reconstruction influence the satisfaction index of reconstructed patients. Methods: A retrospective examination was carried out on patient records from 2016 to 2024 at general hospital of Mexico. The analysis encompassed 210 patients who underwent breast reconstruction during this frame time. The BREAST-Q questionnaire was administered in March 2024 and at various intervals during each patient磗 post-operative care. Patients were stratified according to multiple variables such as: oncological therapy, timing of reconstruction, type of reconstruction and educational attainment. Results: The average age of the participants was 50.3 years. In terms of reconstruction timing, 25.24% underwent immediate reconstruction, while 74.76% opted for delayed reconstruction. When it came to BMI, the average was 26.99 kg/m�. Regarding the type of flap used for reconstruction, the majority (82.86%) had a latissimus dorsi flap. The overall demonstrated a mean psychosocial well-being scale score of 76�6. Conclusions: Breast reconstruction goes beyond physical restoration; it can profoundly impact a patient's emotional recovery, self-image, and quality of life. By addressing not only the physical changes but also the emotional and psychological aspects of breast cancer treatment, reconstruction plays a vital role in helping patients move forward with confidence, resilience, and a sense of empowerment. Regardless of when we first contact the patient, it is always worthwhile to provide her with information and the option of reconstruction.

Reconstruction of a complex lower leg defect following oncologic resection with a combination of inferiorly based peroneus brevis muscle flap and fasciocutaneous flaps: a case report

Wounds and soft tissue defects in the distal third of the leg and ankle remain a challenge. Defects at this site will often require a flap cover. A free flap is an ideal choice for these defects but it has its limitations. The distal peroneus brevis muscle flap is a well-described flap for such defects. Peroneus brevis is an expendable muscle in the leg without much functional deficit. A 38-year-old male patient presented with a chronic ulcer in the right leg for 1year of which biopsy was positive for squamous cell carcinoma that underwent wide local excision with peroneus brevis flap reconstruction and also two local fasciocutaneous flaps. The distally based pedicled peroneus brevis muscle flap is an economical, reliable, and relatively easy procedure for treating defects of the heel, Achilles tendon, and medial and lateral malleolus, extending deep into the ankle.

Sihler's Staining of the Thoracic Cutaneous Nerve and its Significance / Tinción de Sihler del Nervio Cutáneo Torácico y su Relevancia

SUMMARY: Our team has modified Sihler's intramuscular nerve staining method to allow for calculation of nerve density. Therefore, this study aimed to show the overall distribution pattern of the thoracic cutaneous nerves to provide a morphological basis for selecting and matching sensory reconstruction during skin flap transplantation. Twelve Chinese adult cadavers were dissected; the thoracic skin was removed, and the modified Sihler's staining method was performed. Centered around the nipple, the chest skin was divided into four regions: medial-superior, lateral-superior, lateral-inferior, and medial-inferior. The thoracic skin was not only innervated by the branches of the 1st to 7th intercostal and supraclavicular nerves, but also by a small number of nerves that directly reached the skin and passed through the pectoralis major muscle. There is a phenomenon of cross overlap between the branches of adjacent intercostal nerves. The branches of the 2nd to 7th intercostal nerves were distributed in the breast, and the branches of the lateral and anterior cutaneous branches were densely distributed around the nipple, forming a grid-like anastomosis. There was no cross-overlapping innervation between the anterior cutaneous branches on both sides. The density of nerve distribution in the four regions of the chest was in the order of the medial-superior, lateral-superior, lateral-inferior and medial-inferior region, respectively. These results may be used to map sensory regions when designing thoracic skin flaps for reconstruction surgery to obtain improved sensory recovery.

Nuestro equipo ha modificado el método de tinción nerviosa intramuscular de Sihler para permitir el cálculo de la densidad nerviosa. Por lo tanto, este estudio tuvo como objetivo mostrar el patrón de distribución general de los nervios cutáneos torácicos proporcionando una base morfológica para seleccionar y combinar la reconstrucción sensorial durante el trasplante de colgajo de piel. Se diseccionaron 12 cadáveres de individuos adultos chinos. Se eliminó la piel torácica y se realizó el método de tinción de Sihler modificado, centrada alrededor del pezón, la piel del pecho se dividió en cuatro regiones: medial- superior, lateral-superior, lateral-inferior y medial-inferior. La piel torácica no solo estaba inervada por los ramos de los nervios intercostal y supraclavicular 1º a 7º, sino también por un pequeño número de nervios que llegaban directamente a la piel y pasaban a través del músculo pectoral mayor. Existe un fenómeno de superposición cruzada entre los ramos de los nervios intercostales adyacentes. Los ramos de los nervios intercostales 2º a 7º se distribuyeron en la mama, y los ramos de los ramos cutáneos lateral y anterior se distribuyeron densamente alrededor del pezón, formando una anastomosis en forma de rejilla. No hubo inervación cruzada entre los ramos cutáneos anteriores en ambos lados. La densidad de la distribución nerviosa en las cuatro regiones del tórax estaba en el orden de región medial-superior, lateral-superior, lateral-inferior y medial-inferior, respectivamente. Estos resultados pueden ser útiles para mapear regiones sensoriales al diseñar colgajos de piel torácicos para utilizarlos en cirugía de reconstrucción y obtener así una mejor recuperación sensorial.

Bilateral alloplastic temporomandibular joint reconstruction with orthognathic surgery: a case report of idiopathic condylar resorption

Idiopathic condylar resorption (ICR) also known as cheerleader’s syndrome, progressive condylar resorption, idiopathic condylysis, and condylar atrophy can be defined as chronic ongoing changes of condylar shape and decrease in mass. It is characterized by an excessive physical stress to the articular structures of the temporomandibular joint (TMJ) that exceeds the normal adaptive capacity. Consequently, leading to decrease condylar head volume, decrease ramus height, progressive mandibular retrusion in adults, or decreased growth rate in adolescents. A case report of a 30-year-old female based on the history, clinical, and radiographic examination has class II skeletal relationship secondary to bilateral ICR, receded chin, vertical maxillary excess (VME) and canting. Surgical treatment plan was established using 3D Systems, Inc., (“3DS”) VSP® and case was managed by bilateral total alloplastic temporomandibular joint reconstruction (BATMJR) with orthognathic surgery to do LeFort I, bilateral condylectomy, genioplasty, and inferior border osteotomy. The case report includes one-year follow-up which shows stable outcome, emphasizing long-term success of comprehensive treatment strategy in addressing skeletal class II malocclusion associated with ICR.

Disability evaluation after latissimus dorsi muscle transfer in breast reconstruction using DASH score

Background: Breast reconstruction with latissimus dorsi muscle transfer is one of the most frequent procedures at our hospital. The objective is to evaluate if there is any functional impairment after the surgery with a potential impact of patient磗 daily life. Methods: Functional morbidity was analyzed applying the disabilities of the arm, shoulder and hand (DASH) questionnaire and shoulder range of motion with goniometer in 42 patients whose breast reconstruction was between 2016 and 2022 at our hospital. We collected data using Microsoft excel V16.47.1 and analyzed data with statistical package for the social sciences (SPSS) software, v23.0. Results: There was statistically significant difference for disability/symptom DASH score in cases of bilateral reconstruction and for cases undergoing a procedure on the right side versus left side. Conclusions: In patients with bilateral breast reconstruction, we found a greater DASH score in dysfunction and symptoms which associates with poor quality of life, as well as when the flap is on the contralateral extremity of the hand dominance; in those cases, there are other reconstructive procedures that provide greater safety and less disability to the patient. For evaluating extension, we need more prospective and comparative studies with strict follow up of the patients and same series of rehabilitation.

Necrotic loxoscelism in lower limb and reconstruction with skin autograft

Loxesceles are small spiders, from 9 to 25 mm, with a dark brown spot on the dorsal part in the shape of an inverted violin. They are common in northwestern Mexico and can live at temperatures of 8 to 40°C. These spiders are considered of medical importance because their venom is dermonecrotic, with proteolytic and necrotic action, which is generated in two apocrine glands. The cutaneous clinical picture is the most frequent, with edema, erythema and ischemia that tends to evolve to ulceration and deep necrosis. The key to treatment is early debridement to avoid complications. We presented the case of a 57-year-old female patient who developed an inflammatory condition secondary to a fiddler spider bite involving the left lower extremity. Her evolution to necrosis and late diagnosis required surgical debridement and use of negative pressure therapy (VAC), followed by harvesting and placement of partial thickness skin autograft, obtaining a successful aesthetic and functional result.

Management of pilonidal sinus in sacrococcygeal region using Limberg transposition flap with acceptable and safer outcome: a case series

Sacrococcygeal pilonidal sinus is a disease that arises from chronic irritation and secondary inflammation of hair follicles located in the sacrococcygeal and natal region, commonly seen among the young male adult population. There are multiple treatment options available ranging from non-medical to surgical procedure. The present study aims to evaluate the efficacy and complications of Limberg flap reconstruction surgery. 8 consecutive patients underwent Limberg flap reconstruction from October 2022 to February 2023 at Midnapore Medical College with a median follow-up duration of 12 months and were evaluated for various parameters. All patients successfully underwent reconstructive surgery, with minimal post- operative pain, average hospital stay for 7 days, returned to work after 3 weeks, with only 1 patient having superficial surgical site infection (SSI), but no flap necrosis, seroma formation, recurrences so far. Overall the Limberg flap technique is an effective and reliable technique having fewer post-operative complications, low recurrence rate, easily performed with patient satisfaction, and is emerging as the standard of care.

Comparison of the Functional Outcomes of Arthroscopic Anterior Cruciate Ligament Reconstruction through the All-inside and Outside-in Techniques: A Double-Blinded Randomized Controlled Trial / Comparação dos resultados funcionais da reconstrução artroscópica do ligamento cruzado anterior pelas técnicas all-inside e outside-in: Um ensaio clínico controlado, randomizado e duplo-cego

Abstract Objective To compare the functional outcomes of anterior cruciate ligament (ACL) reconstruction with hamstring autograft (HA) through the all-inside (AI) technique with adjustable-loop cortical Endobutton (Smith & Nephew, Watford, Hertfordshire, England) on the sides of the femur and tibia and through the outside-in (OI) technique using an interference screw on the tibial side and a cortical Endobutton on the femoral side. Materials and Methods The present is a double-blinded randomized controlled trial (RCT) of 44 patients undergoing arthroscopic ACL reconstruction from February 2019 to February 2022 in a tertiary care hospital. As per computer-based randomization, the patients were distributed into two groups: the AI and OI groups. Both groups were evaluated for 12 months using the Visual Analog Scale (VAS), the Lysholm Knee Scoring Scale, and part I (pain score) and part II (function score) of the Knee Society Score (KSS). Results On postoperative day 2,the VAS score was significantly higher in the OI group (p = 0.0001), but insignificant (p = 0.807) at 6 weeks. At 3, 6, and 12 months of follow-up, the score on the Lysholm Knee Scoring Scale was significantly higher (p = 0.001) in the AI group. At 6 months, both parts of the KSS showed a significant difference, with the AI group presenting a better outcome (p = 0.04). However, at 12 months, the AI group presented a better score on part I of the KSS, but no differences were observed regarding part II. Conclusion In a follow-up of 12 months, the patients submitted to the AI technique presented better outcome scores and pain relief than those submitted to the OI technique.

Resumo Objetivo Comparar os resultados funcionais da reconstrução do ligamento cruzado anterior (LCA) com autoenxerto de isquiotibiais pela técnica all-inside (AI) com Endobutton (Smith & Nephew, Watford, Hertfordshire, Inglaterra) cortical de alça ajustável nos lados do fêmur e da tíbia e pela técnica outside-in (OI) com parafuso de interferência no lado tibial e Endobutton cortical no lado femoral. Métodos Trata-se de um ensaio clínico controlado, randomizado e duplo-cego com 44 pacientes submetidos à reconstrução artroscópica do LCA de fevereiro de 2019 a fevereiro de 2022 em um hospital de cuidados terciários. De acordo com a randomização por computador, os pacientes foram distribuídos em dois grupos: AI e OI. Ambos os grupos foram avaliados durante 12 meses pela Escala Visual Analógica (EVA), a Escala de Pontuação do Joelho de Lysholm e pela parte I (pontuação de dor) e a parte II (pontuação de função) da escala Knee Society Score (KSS). Resultados No segundo dia de pós-operatório, a pontuação média na EVA foi significativamente maior no grupo OI (p = 0,0001), mas insignificante (p 0,807) às 6 semanas. Aos 3, 6 e 12 meses de acompanhamento, a pontuação na Escala de Lysholm (p = 0,001) foi significativamente maior no grupo AI. Aos 6 meses, ambas as partes da KSS apresentam uma diferença significativa, com o grupo AI apresentando um desfecho melhor (p = 0,04). No entanto, aos 12 meses, o grupo AI apresentou uma pontuação melhor na parte I da KSS, mas não foram observadas diferenças na parte II. Conclusão Em um acompanhamento de 12 meses, os pacientes submetidos à técnica AI apresentaram melhores pontuações de desfecho e alívio da dor do que aqueles submetidos à técnica OI.

Colgajos libres para reconstrucción de cabeza y cuello: experiencia de un centro oncológico chileno

Objetivo: eportar nuestra experiencia en la reconstrucción de pacientes con tumores de cabeza y cuello. Materiales y Métodos: Revisión retrospectiva de fichas clínicas de los pacientes sometidos a reconstrucciones con colgajos microquirúrgicos entre los años 2007 y 2020 en la Fundación Arturo López Pérez. Resultados: En este período 186 cirugías fueron realizadas, lo que correspondió a 173 pacientes, la mediana de edad fue de 59 años, 55% eran hombres. 29% correspondieron a rescates quirúrgicos. Al diagnóstico 110 (54%) tenían una enfermedad localmente avanzada (T3-T4). El sitio anatómico más frecuentemente reconstruido fue la cavidad oral, 83(45%). La histología más frecuente fue el carcinoma escamoso. Los colgajos más utilizados fueron el osteocutáneo de peroné, anterolateral de muslo (ALT) y antebraquial. La sobrevida global a 5 años fue 44,3%, con amplia variabilidad entre las distintas histologías. Discusión: En el análisis de nuestros resultados en dos períodos de siete años (2007-2013 y 2014-2020), el porcentaje de falla de colgajo disminuyó (10% versus 2,6%; p = 0,012); al igual que la estadía hospitalaria que disminuyó (de una mediana de 23 días a 18 días; p = 0,041). El uso del colgajo ALT aumentó de 14% a 29%, esto último aprovechando la versatilidad del colgajo de ALT para la fabricación de múltiples paletas cutáneas, que permiten reconstrucciones más complejas. Conclusión: Las reconstrucciones microquirúrgicas en nuestra institución son una opción estandarizada, confiable y comparable con centros internacionales.

Objective: To report our experience, and success rate for head and neck reconstruction in a Chilean oncologic center. Methods: Charts were reviewed retrospectively for all patients treated surgically for head and neck tumors that needed a free flap reconstruction from 2007 to 2020. The demographics and epidemiologic variables were described. Overall survival was calculated with the Kaplan-Meier method. Results: One hundred and eighty-six operations were performed on 173 patients; the median age was 59 years, and 55% were male. Twenty-nine percent of patients required a surgical rescue. The most frequently used free flaps were the anterolateral thigh, fibula osteocutaneous, and radial forearm. A second free flap was needed in 13 patients. Five-year overall survival for the whole cohort was 44.3% and varied according to histology: 28.2% for squamous cell carcinoma and 68.9% for salivary gland histology. Discussion: In analysis of our results in two seven-year periods (2007-2013 and 2014-2020), the percentage of flaps that failed decreased (10% earlier versus 2.6% later; p =.012); the length of hospital stay declined (median 23 days earlier vs 18 days later; p =.041), and the use of anterolateral thigh flaps increased 14% vs 29%, taking advantage of the versatility of the anterolateral thigh flap for the fabrication of multiple skin palettes, allowing for more complex reconstructions. Conclusion: In our institution, outcomes with free flap reconstruction for head and neck were satisfactory and improved with operator experience.

Experiencia en reconstrucción del paciente gran quemado agudo con microcirugía

Introducción: Las quemaduras son un trauma frecuente de ocurrencia en todo el mundo, que ha experimentado importantes aumentos de sobrevida. Su manejo requiere la reposición de la barrera cutánea, lo que se logra en la mayoría de los casos con el uso de injertos dermo-epidérmicos. Sin embargo, existen algunas veces lesiones complejas que no logran sanar mediante injertos, arriesgando la funcionalidad o vitalidad del área comprometida, que requerirán reparaciones complejas con el uso de colgajos microqui- rúrgicos (CM). Metodología: Estudio descriptivo retrospectivo en que incluimos todos los pacientes gran quemados agudos admitidos en Hospital de Urgencia de la Asistencia Pública, Servicio de Quemados y Rehabilitación, desde abril de 2019 hasta diciembre de 2020 los que fueron manejados con colgajo micro- quirúrgico. Revisión de ficha clínica para obtención de variables demográficas y del procedimiento con análisis de frecuencia de ocurrencia. Resultados: En nuestro período de estudio hubo 376 ingresos y 21 pacientes recibieron 25 CM. La mayoría hombres (96%), edad promedio 40 años, superficie comprometida promedio 16%, mecanismo más frecuente electricidad (64%) y fuego (32%). La ubicación más frecuente del colgajo fue en extremidades inferiores (64%) y el colgajo más utilizado fue el anterolateral de muslo (80%). Tiempo medio a reconstrucción fueron 40 días, no hubo pérdida total del colgajo. Discusión: se realizó un CM en 5,6% de nuestros ingresos, la mayoría durante el intervalo primario tardío, sin pérdidas totales. Estos resultados representan la consolidación de la técnica que permite su uso en el paciente gran quemado durante su etapa aguda, permitiendo coberturas complejas y manteniendo riesgo quirúrgico y tasa de complicaciones adecuada con enfoque en rehabilitación precoz.

Introduction: Burns are the fourth most common trauma. Microsurgery has evolved as a valuable tool in the acute setting allowing early closure of complex wounds in order to avoid infection, maintain function or even for limb salvage in one stage reconstruction. We present our experience at our burn center in Chile. Method: We performed a retrospective analysis of all major burn patients admitted in the National Burn Center in Chile who received a microsurgical flap in the period between April 2019 to December 2020. Results: A total of 21 patients had 25 free flaps. All patients but one were male (96%), mean age 40 years (range 20-69 years). Total body surface area means 16% (range 1-64%). Most of the injuries were caused by high voltage electricity (64%) and fire (32%). 64% were performed in lower limbs and 36% in upper limbs. In 80% of the cases, anterolateral thing flap was chosen. Mean time to reconstruction was 40 days. We didn't experience a total flap lost in this series. Discussion: In the acute phase microsurgery proved to be safe and feasible albeit a small surgical indication. We performed a flap in 5.6% of our admissions, mostly during late primary interval with no flaps lost. Our results acknowledge the consolidation of the technique for its use in the acutely burned setting, allowing complex coverage while maintaining the surgical risk and an internationally acceptable rate of losses and complications.

The deep inferior epigastric artery perforator flap: a review

Breast cancer is recognized worldwide as a major health problem among women due to its high incidence and high mortality and morbidity rates. Breast reconstruction is an approach of great value for those patients who underwent mastectomy, impacting their quality of life and psychological stress. The deep inferior epigastric artery perforator (DIEP) flap was described as the preferred graft for breast reconstruction with an autologous flap by surgeons because it represented a decrease in complications for the time and obtained better results. DIEP flap reconstruction requires microsurgical skills as well as continuous monitoring of the patient to identify and resolve possible associated complications.

Effective endovascular reconstruction using multiple leo stents and silk flow-diverting stents for asymptomatic extracranial internal carotid artery dissection: a case report

Extracranial carotid artery dissection (ECAD), although infrequent, represents the predominant form of artery dissection within the brain. It accounts for 25% of young-onset ischemic strokes in adults. Its atypical presentation and limited availability of high-quality evidence underscore the importance of precision medicine in its management. This study aimed to illustrate a combined approach utilizing multiple scaffolding Leo stents and Silk flow-diverting stents to manage asymptomatic ECAD a week after the onset of acute ischemic stroke. A 40-year old Indian male with uncontrolled hypertension was admitted due to acute vestibular syndrome. His brain computed tomography (CT) scan showed cerebellar infarct. However, his angiographic cervical CT scan showed asymptomatic ECAD, which was confirmed with digital subtraction angiography. He was therefore managed with optimal antihypertensive agents and dual antiplatelet. The endovascular reconstruction procedure initiated one week after the onset of stroke by employing one scaffolding Leo stent and one Silk flow-diverting stent at his right internal carotid artery. He was discharged three days following the endovascular procedure and presented no complications until three-month follow-up. This safe approach could be considered for individuals with ECAD to help prevent secondary strokes, particularly among those in the productive age group.

Perineal reconstruction with V-Y advancement flap at the general hospital of Mexico: a case report

Extramammary Paget's disease represents a rare entity whose only definitive management is resection, resulting in significant raw areas requiring reconstruction by the plastic surgeon. Currently, bilateral gluteal advancement VY fasciocutaneous flaps have been for some time one of the best options for perineal reconstruction, allowing for adequate coverage, low morbidity at the donor site, and satisfactory aesthetic and functional outcomes. In this study, we report the performance of a bilateral VY advancement flap for perineal reconstruction in the Plastic and Reconstructive Surgery Department of the General Hospital of Mexico.

A clinical study on reconstruction of traumatic auricular defects

The auricle or external ear is an important aesthetic subunit of the face. The intricate anatomy due to multiple convolutions along with the thin integument poses a challenge to the reconstructive surgeon. The prominent position of the ear on either side of the face and over a bony prominence makes it more prone for injury. The objective of the study is to describe various traumatic auricular defects and their subsequent reconstructive methods. A retrospective analysis of 15 patients with traumatic auricular defects was carried out over a period of 2 years between the time period of January 2022 and December 2023. Various reconstructive methods such as Primary closure, use of chondral grafts and chondrocutaneous flaps, local flaps were employed depending on the size of the defect and according to the reconstructive ladder. Out of 15 patients, 12 were male and 3 were female, with traumatic ear defects secondary to road traffic accidents (12) and human bite (3). The site of the defect was upper 1/3d (8), upper+middle 1/3rd (3), lower+middle third (2), middle third (1) and lower 1/3rd (1) of the auricle. They were managed by debridement and primary closure in 5 cases, post auricular flap in 5 cases, preauricular flap in 2 cases, peninsular conchal island flap+postauricular flap in 1 case, and bilobed flap in 1 case. All the flaps settled well. 4 patients needed secondary procedures in the form of flap division and contour corrections. This study employed a variety of reconstruction methods of the auricle as per the reconstructive ladder. Some of the patients required secondary procedures. All patients in this study had a satisfactory end aesthetic outcome with no major complications.

Versatility and modifications of the cross-finger flap in reconstruction of digital soft tissue defect

Background: Hand injuries can cause major functional and cosmetic concerns. The cross-finger flap (CFF) is an effective treatment for complex finger defects. While CFF has typically been employed to treat volar aspect abnormalities, new versions now address a larger variety of digital soft tissue defects. The aim of the study was to evaluate the clinical outcome of various modified techniques of cross-finger flap which are used to reconstruct different soft tissue defect of fingers. Methods: This was a prospective observational study carried out in the department of Burn and Plastic Surgery at Dhaka Medical College Hospital, Dhaka from September 2018 to February 2020. Forty (40) patients who presented with different soft tissue defect of fingers included in this study according to inclusion and exclusion criteria. Results: The study involved predominantly male participants (80%), with a mean age of 31.70�.28 years. The most common soft tissue defect site was the volar area (47.5%), and various modified cross-finger flap techniques were employed. The majority of patients achieved excellent functional outcomes, with 82.5% classified as good, 12.5% as satisfactory, and 5.0% as poor. Conclusions: The modifications of the cross-finger flap are versatile and useful for different sites of digital injuries with good functional outcome.

Reconstrucción auricular con implantes mastoideos utilizando el sistema Novaloc / Implant supported auricular reconstruction using the Novaloc system

La microtia es un padecimiento congénito de etiología desconocida que se puede presentar asociado a síndromes, su frecuencia es mayor en hombres, tiene predilección por el oído derecho. Se han propuesto distintas alternativas de tratamiento tanto estéticas como funcionales que disminuyan riesgos y aumenten la calidad de vida de los pacientes. Entre los tratamientos más comunes se encuentra el injerto costocondral, siendo una alternativa viable, aunque de mayor riesgo y que puede necesitar varios procedimientos quirúrgicos con el fin de lograr el mejor resultado estético; por lo mismo, uno de los tratamientos más realizados actualmente, es la reconstrucción auricular con implantes osteointegrados que se colocan en la región mastoidea y soportan una prótesis auricular. Se presenta el caso de un paciente masculino quien fue rehabilitado con implantes mastoideos ostoeintegrados para reconstrucción auricular implantosoportada. Las prótesis implantosoportadas reducen la necesidad de realizar cirugías correctivas y posibilitan la buena higiene de la prótesis al ser ésta removible, pero sin sacrificar su estabilidad. Los sistemas más utilizados son los mismos que se emplean en sobredentaduras, ya que el diseño del aditamento transmucoso, se adapta perfectamente al grosor del epitelio en la región mastoidea, por lo que es una excelente alternativa de tratamiento (AU)

Microtia is a congenital condition of unknown etiology that can occur associated with syndromes. Its frequency is greater in men and has a predilection for the right ear. Different treatment alternatives, both aesthetic and functional, have been proposed that reduce risks and increase the quality of life of patients. Among the most common treatments can be found the costochondral graft being a good alternative although greater risk of failure and the probability of several surgeries to get the best aesthetic result. Because of that one of the most used treatments is the placement of osseointegrated implants that can hold a prosthetic ear. Here is a case of a male patient who was rehabilitated with osseointegrated mastoid implants for ear reconstruction. Implant-supported prostheses significantly reduce the number of surgeries that must be performed and is a good option to maintain excellent hygiene as the prosthetic ear is removable, without compromising stability. The most common system is the same as those used in overdentures since the design of the transmucosal attachment fits perfectly to the thickness of epithelium in mastoid region (AU)

Radical surgical approach to chronic suppurative osteomyelitis: Case report / Abordaje quirúrgico radical de una osteomielitis crónica supurativa: reporte de caso

Abstract Diabetes mellitus is a systemic condition potentially related to an increased risk of progression of various infections such as chronic osteomyelitis by accelerating the inflammatory process with bone tissue necrosis and suppuration. Therefore, if there is no proper management of these infections, they can be life-threatening as they spread to deeper spaces in the head and neck. We describe the case of a 52-year-old male patient with a history of diabetes mellitus and grade III osteoarthritis who was diagnosed with chronic suppurative osteomyelitis of the mandible. He underwent a multidisciplinary surgical intervention in which he underwent a hemimandibulectomy with immediate mandibular reconstruction. The present case highlights the importance of early and radical treatment of patients with chronic suppurative osteomyelitis of the mandible and systemic comorbidities. In addition, this case presents a review of diabetes mellitus and the risk of developing odontogenic infections and complications when invading deeper spaces in the head and neck. Therefore, in this population, careful planning is required for early surgical and pharmacological treatment.

Resumen La diabetes mellitus es una condición sistémica potencialmente relacionada con un mayor riesgo de progresión de diversas infecciones como la osteomielitis crónica al acelerar el proceso inflamatorio con necrosis del tejido óseo y supuración. Por lo tanto, si no hay un manejo adecuado de estas infecciones pueden ser potencialmente mortales al llegar a propagarse a espacios más profundos de la cabeza y cuello. Describimos el caso de un paciente varón de 52 años con antecedentes de diabetes mellitus y osteoartrosis grado III a quien se le diagnosticó de osteomielitis crónica supurativa mandibular. Se le realizó una intervención quirúrgica multidisciplinaria en la cual se le realizó una hemimandibulectomía con reconstrucción mandibular inmediata. El presente caso destaca la importancia del tratamiento temprano y radical de los pacientes con osteomielitis mandibular crónica supurativa y comorbilidades sistémicas. Además, en este caso se presenta una revisión sobre la diabetes mellitus y el riesgo de desarrollar infecciones odontogénicas y complicaciones al invadir espacios más profundos de la cabeza y cuello. Por lo tanto, en esta población se requiere de una planificación cuidadosa para realizar un tratamiento quirúrgico y farmacológico temprano.

Successful endovascular reconstruction of symptomatic vertebrobasilar dolichoectasia using multiple Leo stents and nondominant vertebral artery occlusion: a case report

Vertebrobasilar dolichoectasia (VBD) is a rare vascular anomaly of increased diameter, length, and tortuosity of vertebral and/or basilar artery, but debilitating due to its risk of ischemia, hemorrhage, and nerve or brain compression. The management is also controversial due to various possible clinical manifestation and outcome. This study aimed to describe a combined approach of multiple scaffolding Leo stents and nondominant vertebral artery occlusion as a definitive approach to reconstruct vertebrobasilar arteries. A 40-year old male presented with severe headache and reduced consciousness, which was explained with brain CT findings of subarachnoid hemorrhage and hydrocephalus. Further etiologic approach until digital subtraction angiography revealed VBD. An endovascular reconstruction approach was considered one month following the event onset using multiple scaffolding Leo stents from left vertebral to basilar artery with right vertebral artery occlusion. This stent had the best radial strength, lowest bending stiffness, highest kink resistance, highest bending wall coverage, and lowest cell size, which provided strong vascular reconstruction properties. Combined nondominant vertebral artery occlusion was also performed to avoid the disturbance of flow-diverting pathway by the stents. Double antiplatelet was administered from three weeks following the event onset afterwards. The patient抯 condition improved at three-month follow-up. This case report presented that combined multiple Leo stents and nondominant vertebral artery occlusion may be considered as an approach to successful endovascular reconstruction for symptomatic VBD.

Use of frontal flap for reconstruction of malar region following arteriovenous malformation resection: a case report

Arteriovenous malformations (AVMs) are rare congenital vascular anomalies characterized by abnormal artery-vein connections. These malformations often occur intracranially but can be found in extracranial regions, presenting unique clinical challenges. Diagnosis and staging, typically using the Schobinger clinical classification, are essential, and various imaging techniques aid in the process. Treatment of AVMs is a multidisciplinary effort, with minimally invasive endovascular procedures being preferred, and surgical resection considered for extensive cases. In this case report, a 52-year-old male with an AVM in the malar region underwent successful treatment. The procedure involved preoperative marking, anesthesia, flap division, AVM resection, and flap placement, followed by suturing and a second surgical stage. The successful utilization of a contralateral frontal flap for reconstruction following AVM resection is highlighted. This case underscores the importance of a multi-stage surgical approach and careful flap preservation in AVM treatment, emphasizing the skills of surgeons. Collaboration among various medical specialties is crucial for effectively managing AVMs, combining embolization, resection, and reconstruction for tailored treatment that improves both function and aesthetics.

Abordaje y tratamiento de un paciente con trauma laríngeo externo de grado IV, según la clasificación de Schaefer-Fuhrman: reporte de un caso / Approach and treatment of a patient with grade IV external laryngeal trauma, according to Schaefer-Fuhrman's classification: a case report

RESUMEN Introducción: El trauma laríngeo externo es una lesión infrecuente. Según la clasificación de Schaefer-Fuhrman, el grado V se refiere a la separación laringotraqueal completa. En el contexto del trauma, la mortalidad es del 80 %. Hasta la fecha, no se han publicado reportes de casos similares con resultados favorables. El objetivo de este estudio es describir la evolución de un paciente con trauma laríngeo externo de grado IV. Presentación del caso: Se presentó un paciente masculino de 22 años con una lesión completa de cartílago tiroides y apertura de laringe y faringe. El paciente fue sometido a una traqueostomía y faringostomía. El día 4 de internación, se lo desvinculó de la ventilación mecánica, y el día 8, se le realizó una gastrostomía. El día 11, se solicitó una prótesis para la reconstrucción laríngea, y el paciente fue trasladado a cuidados intermedios. A los 15 días, adquirió la independencia funcional. El día 59, se llevó a cabo una cirugía de reconstrucción, y el día 71, el paciente logró tolerar la oclusión de la cánula con protección de la vía aérea. Luego de 48 horas, cumplió con los criterios de decanulación, y el día 79, logró la decanulación. Conclusión: Se describe a un paciente con trauma laríngeo externo de grado IV, según la clasificación de Schaefer-Fuhrman, que es una lesión asociada con una alta morbimortalidad. No obstante, este estudio destaca resultados favorables tanto en términos de sobrevida como de recuperación funcional.

ABSTRACT Introduction: External laryngeal trauma is an uncommon injury. According to Schaefer-Fuhrman's classification, grade V refers to the complete laryngotracheal disruption. In the trauma context, the mortality rate is 80 %. To date, no case reports with favorable outcomes have been published. The aim of this study is to describe the clinical course of a patient with grade IV external laryngeal trauma. Presentation of the case: A 22-year-old male patient presented with a complete lesion of the thyroid cartilage and larynx and pharynx opening. The patient underwent a tracheostomy and pharyngostomy. On day 4 of hospitalization, the patient was withdrawn from mechanical ventilation, and on day 8, a gastrostomy was performed. On day 11, a prosthesis for laryngeal reconstruction was requested, and the patient was transferred to intermediate care. On day 15, he gained functional independence. On day 59, a reconstruction surgery was performed, and on day 71, the patient tolerated occlusion of the cannula with airway protection. After 48 hours, he met the decannulation criteria, and on day 79, he was decannulated. Conclusion: We described a patient with grade IV external laryngeal trauma, according to Schaefer-Furhman's classification, which is an injury associated with high morbimortality. Nevertheless, this study emphasizes favorable outcomes in terms of both survival and functional recovery.
