ABSTRACT

Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.

ABSTRACT

ABSTRACT Cemento-osseous dysplasia (COD) is a non-neoplastic process usually confined to the tooth-bearing areas of the jaws or edentulous alveolar processes. It is mostly seen in women during the third and fourth decades of life. The mandible is the most common location in 70% of cases in the premolar-molar region. This case report presents a case of cemento-ossifying fibroma with clinical features and radiographic features in a 23-year-old female patient.

ABSTRACT

RESUMEN: El Leiomioma es una neoplasia benigna originada en el tejido muscular liso por lo que puede manifestarse en cualquier región del cuerpo humano que contenga músculo liso, siendo el sitio más común el útero, la piel y en el tracto gastrointestinal. La escasa cantidad de tejido muscular liso en boca hace que su manifestación oral sea infrecuente, representando solo 0.06 % del total de este tipo de tumores. Los sitios más afectados suelen ser los labios, las mejillas, el paladar, la lengua y encías. Histológicamente se distinguen tres tipos: el Leiomioma Sólido, Angioleiomioma (Vascular) y Leiomioma Epitelioide (Leiomioblastoma). El origen de esta neoplasia en boca suele ser la túnica media de los vasos sanguíneos. El Leiomioma intraóseo suele ser aún menos frecuente, y con un diagnóstico diferencial complejo, con histopatología que en varias ocasiones no suele ser fácil de clasificar. Si bien es definida como un tumor benigno, su manifestación intraósea puede llegar a ser localmente agresiva y con un diagnóstico controversial, debiendo abordarse muchas veces como una neoplasia maligna. El objetivo de este artículo es presentar una revisión de la literatura de esta variante intraósea de Leiomioma situada en mandíbula, sus consideraciones clínicas y un algoritmo de tratamiento.


ABSTRACT: Leiomyoma is a benign neoplasm, the origin is the smooth muscle tissue that can be found in any area of the human body, which contains smooth muscle tissue. The most common regions it can be located, are the uterus, the skin and the gastrointestinal tract. The low quantity of muscle tissue in the mouth leads to infrequent oral manifestation, representing only 0.06 % of these tumors. The most affected regions are the lips, cheeks, palate, tongue and gums. The Histologic classification is: Solid Leiomyoma, Angioleiomyoma (vascular) and Epithelioid Leiomyoma (Leiomyoblastoma). The origin of this tumor in the mouth is the tunica media of the blood vessels. Nevertheless, and in spite of being defined as a benign tumor, it can be extremely aggressive, be subject to controversial diagnosis, and must often be treated as a malign neoplasm. The Intraosseous Leiomyoma is infrequent and presents a complicated differential diagnosis, with a histopathology that many times cannot be easily classified. The aim of this article is to present a review of intraosseous variant Leiomyoma in the mandible, the clinicians´ considerations and a treatment algorithm.

ABSTRACT

Osteochondromas are benign osteogenic tumors that can attain great size, which may require resection and additional treatment to restore the jaw's shape and function. In this report, an osteochondroma located on the mandibular ramus and neck of the condyle was resected and reconstructed simultaneously through a total joint replacement. After the surgery, the patient remains asymptomatic and recovers opening and closing ranges, phonation and the masticatory function. The immediate reconstruction after resection is a good alternative to avoid a second operation and the presurgical virtual planning ensures the complete removal of the lesion using cutting guides and covering the entire defect with a customized alloplastic joint prosthesis.


Los osteocondromas son tumores osteogénicos benignos que pueden alcanzar grandes tamaños, los cuales requieren de resección quirúrgica y generalmente de algún tratamiento adicional para restaurar la forma y la función mandibular. En este caso, un osteocondroma localizado en la rama mandibular y el cuello del cóndilo fue reseccionado y reconstruido simultáneamente a través de un reemplazo articular total. Después de la cirugía, el paciente permanece asintomático y recupera los intervalos de apertura y cierre, la fonación y la función masticatoria. La reconstrucción inmediata después de la resección es una buena alternativa para evitar una segunda operación, y la planificación virtual prequirúrgica garantiza la eliminación completa de la lesión utilizando guías de corte y cubriendo todo el defecto con una prótesis articular aloplástica personalizada.

ABSTRACT

ABSTRACT: Central ossifying fibroma is a lesion in which diagnosis has proved intriguing and unclear for presenting clinical, radiographic, and even histopathological similarities to other types of lesions such as the fibrous dysplasia of bone and cement-bone dysplasia. It is a benign neoplasm of uncertain etiology and slow development in which the mandible is affected more frequently than the maxilla. We described a case of central cemento-ossifying fibroma involving the right mandible of a thirty-five-female patient by presenting its clinical, radiographic, and histological characteristic sand discussing some differential diagnoses.


RESUMEN: El fibroma cemento-osificante central es una lesión que requiere un diagnóstico diferencial ya que muestran similitud clínica, histológica y radiológica con la displasia fibrosa y con la displasia cemento-ósea. Esta lesión es un tumor benigno de etiología incierta, presenta crecimiento lento y afecta principalmente la mandíbula más que el maxilar. Se reporta un caso de un paciente de sexo femenino de 35 años, diagnosticada con fibroma cementoosificante central que le afectó el lado derecho de la mandíbula. Se describen las características clínicas, histológicas y radiológicas de la paciente y se discuten los diversos diagnósticos diferenciales.

ABSTRACT

Abstract Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor of the jaws, histologically characterized by the presence of agglomerates of cells with eosinophilic cytoplasm. The patient, a 62-year-old Caucasian woman, presented an intraosseous lesion in the mandibular symphysis. A clinical examination revealed a discrete volumetric increase with a hard consistency, palpable to extraoral and intraoral examinations. Imaging studies revealed an extensive radiolucent area, without defined limits, extending from the region of the right second premolar to the left canine. Incisional biopsy analysis indicated a diagnosis of CCOC. The treatment proposed was segmental resection of the mandible with a safety margin. After six months without recurrence, definitive mandibular reconstruction was performed using an iliac crest graft, followed by rehabilitation with implant-supported denture after five months. After three years of post-resection follow-up, the patient has shown no evidence of recurrence or metastasis. She continues to be under follow-up. To conclude, CCOC must be considered a malignant tumor with aggressive behavior. Previous studies have shown that resection with free margins is a treatment with a lower rate of recurrence. Nevertheless, long-term follow-up is necessary for such patients.

ABSTRACT

Abstract: Salivary duct injury can be idiopathic, iatrogenic, or post-trauma and may result in sialocele or fistula. Most injuries regress spontaneously and botulinum toxin A is one of several therapeutic possibilities. We report a case of iatrogenic injury to the parotid duct after Mohs' micographic surgery for a squamous cell carcinoma excision in the left jaw region, treated by injection of botulinum toxin type A. Although the fistula by duct injury can be self-limiting, botulinum toxin injection by promoting the inactivity of the salivary gland allows rapid healing of the fistula.

ABSTRACT

Here is described a case of ameloblastic fibrosarcoma (AFS) affecting the posterior mandible of a woman who was treated surgically and recovered without signs of recurrence or metastasis after 12 years of follow-up. Tumor sections were immunostained for cell cycle, epithelial and mesenchymal markers. Immunohistochemical analysis evidenced high Ki-67 positivity in stromal cells (mean of 20.9 cells/High power field). Epithelial cells displayed strong positivity for p53, p63 and cytokeratin 19. In addition to the case report, a systematic review of current knowledge is presented on the AFS’s clinical-demographic features and prognostic factors. Based on the review, 88/99 cases were diagnosed as AFS, 9/99 as ameloblastic fibro-odontosarcoma and 2/99 as ameloblastic fibrodentinosarcoma. All these lesions displayed very similar clinical-demographic and prognostic features. Moreover, the review provided evidence that first treatment, regional metastasis, distant metastasis and local recurrence were significant prognostic values for malignant odontogenic mesenchymal lesions. Based on the findings, segregation among ameloblastic fibrosarcoma, ameloblastic fibrodentinosarcoma and ameloblastic fibro-odontosarcoma seems illogical, considering all these lesions have similar predilections and outcomes.


Resumo Aqui é descrito um caso de fibrossarcoma ameloblástico afetando região posterior da mandíbula de uma mulher. Após o tratamento, a paciente ficou livre da doença durante os 12 anos de acompanhamento. Foi realizado imunohistoquimica para marcadores epiteliais, mesenquimais e do ciclo celular. Além disso, uma revisão sistemática de literatura também foi realizada, na tentativa de descobrir as características clínico-demográficas e fatores prognósticos da lesão. 88/99 casos foram diagnosticados como fibrossarcoma ameloblastico, 9/99 como fibro-odontosarcoma ameloblastico e 2/99 como fibrodentinosarcoma ameloblastico. Todas estas lesões exibem características clínico-demográficas e prognósticos muito semelhantes. Além disso, esta revisão forneceu evidências de que primeiro tratamento, metástases regionais, metástases à distância e recorrência local são valores prognósticos significativos para lesões odontogênicas mesenquimais malignas. A análise imunohistoquímica demonstrou elevada marcação positiva em células do estroma para Ki-67 (média de 20,9 células /HPF). As células epiteliais exibiram forte marcação para p53, p63 e citoqueratina 19. A segregação entre fibrosarcoma ameloblastico, fibrodentinosarcoma ameloblastico e fibro-odontosarcoma ameloblastico é ilógica, uma vez que todas essas lesões têm predileções e resultados semelhantes.

ABSTRACT

ABSTRACT Jawbone reconstruction after tumor resection is one of the most challenging clinical tasks for maxillofacial surgeons. Osteogenic, osteoinductive, osteoconductive and non-antigenic properties of autogenous bone place this bone as the gold standard for solving problems of bone availability. However, the need for a second surgical site to harvest the bone graft increases significantly both the cost and the morbidity associated with the reconstructive procedures. Bone grafting gained an important tool with the discovery of bone morphogenetic proteins in 1960. Benefit of obtaining functional and real bone matrix without need of second surgical site seems to be the great advantage of use bone morphogenetic proteins. This study analyzed the use of rhBMP-2 in unicystic ameloblastoma of the mandible, detailing its structure, mechanisms of cell signaling and biological efficacy, in addition to present possible advantages and disadvantages of clinical use of rhBMP-2 as bone regeneration strategy.


RESUMO A reconstrução óssea dos maxilares após ressecções tumorais é uma das tarefas mais difíceis para o cirurgião maxilofacial. As propriedades osteogênicas, osteoindutoras, osteocondutoras e não antigênicas do osso autógeno o colocam como o padrão-ouro para a solução de problemas de disponibilidade óssea. Entretanto a coleta do enxerto ósseo necessita de um segundo sítio cirúrgico, aumentando significativamente o custo e a morbidade associados ao procedimento reconstrutivo. A enxertia óssea ganhou uma excelente ferramenta com a descoberta das proteínas ósseas morfogenéticas na década de 1960. O benefício da obtenção de matriz óssea verdadeira e funcional, sem a necessidade de um segundo sítio cirúrgico, parece ser a grande vantagem do uso das proteínas ósseas morfogenéticas. Neste contexto, o objetivo deste estudo foi analisar a utilização da rhBMP-2 na regeneração óssea de ameloblastoma mandibular unicístico, detalhando sua estrutura, seus mecanismos de sinalização celular e sua eficácia biológica, além de apresentar potenciais vantagens e desvantagens da utilização clínica das rhBMP-2, enquanto estratégia regenerativa.

ABSTRACT

The aim of this study was to evaluate the feasibility of endoscopy to remove keratocystic odontogenic tumors (KCOTs) with virtual 3D mandibular images. Fifteen patients (mean age, 40.27±14.58 years) who underwent endoscopic mandibular KCOT enucleation between May 2009 and October 2009 were included. Virtual 3D mandibular reconstructions derived from computed tomography (CT) imaging were generated for all patients. Recurrence and pathological fracture were evaluated as the primary outcome variables at 1 and 12 months after operation. Secondary infection and inferior alveolar nerve injury were evaluated as the secondary outcome variables at 1 and 6 months after operation. None of the 15 patients exhibited signs of recurrence or pathological fracture after operation. During long-term follow-up, no symptoms of inferior alveolar nerve injury or secondary infection were observed and no signs of recurrence were found in any of the patients. Endoscopy helps surgeons to remove mandibular KCOTs with small incisions. Moreover, endoscopy can provide clear and magnified views and help to avoid damage to the inferior alveolar neurovascular bundle. Therefore, under the support of preoperative virtual 3D mandibular images, the application of endoscopy to remove the tumors should be considered to be a treatment option for KCOTs.

ABSTRACT

Extensive resection of tumor often results in bone and soft tissue defects that cause functional and esthetic consequences. The reconstructive surgery is extremely important for the rehabilitation of these patients. The purpose of this study is to report on the use of Hyperbaric Oxygen therapy (HBO) in the case of a large ameloblastoma treated with segmental resection and reconstructed immediately with nonvascularized bone graft (NVBGs) from iliac crest. A 41-year-old woman was referred to our department because of paresthesia of the inferior alveolar nerve and history of swelling in the molar and ramus region of the left mandible. Panoramic radiograph depicting well-defined multilocular radiolucency extending from second pre-molar region to the left ramus region. An incisional biopsy confirms the diagnosis of solid ameloblastoma. The treatment of choice was segmental mandibular resection and immediate mandibular reconstruction using NVBGs from iliac crest, followed by removal of internal fixation and placement of dental implants with immediate loading. The patient received preoperative HBO (a 90-min session at 2.2-2.4 atmospheres, five times per week for two weeks, for a total of up to 10 sessions). Postoperative HBO (10 further 90-min sessions) was administered within 2weeks. The patient received rehabilitation with a mandibular implant-supported fixed complete dental prosthesis. The present study showed successful management of mandibular ameloblastoma that associated extensive surgery, immediate reconstruction with NVBGs from iliac crest, hyperbaric oxygen therapy and dental implants. These combined procedures allowed removal of lesion and reestablishment of mandibular contour and function.


La resección extensa de un tumor a menudo da lugar a defectos del hueso y de los tejidos blandos, que causan consecuencias funcionales y estéticas. La cirugía reconstructiva es extremadamente importante para la rehabilitación de estos pacientes. El propósito de este estudio fue informar sobre el uso de la terapia de oxígeno hiperbárico (HBO) en un caso de un ameloblastoma de gran tamaño, tratado con resección segmentaria y reconstruido inmediatamente con injerto óseo no vascularizado (IONV) de la cresta ilíaca. Una mujer de 41 años fue derivada a nuestro servicio por parestesia del nervio alveolar inferior e historia de hinchazón en la región molar y ramina de la mandíbula izquierda. Radiografía panorámica que muestra una radiolucencia multilocular bien definida que se extiende desde la segunda región pre-molar hasta la región de la rama izquierda. Una biopsia incisional confirma el diagnóstico de ameloblastoma sólido. El tratamiento de elección fue la resección mandibular segmentaria y la reconstrucción mandibular inmediata mediante IONV de cresta ilíaca, seguido de la eliminación de la fijación interna y la colocación de implantes dentales con carga inmediata. La paciente recibió OHB preoperatoria (una sesión de 90 minutos a 2.2-2.4 atmósferas, cinco veces por semana durante dos semanas, para un total de hasta 10 sesiones). La OHB postoperatoria (10 sesiones adicionales de 90 minutos) se administró en 2 semanas. La paciente recibió rehabilitación con una prótesis dental fija con implante mandibular. El presente estudio mostró un manejo exitoso del ameloblastoma mandibular asociado a una cirugía extensa, reconstrucción inmediata con IONV de cresta ilíaca, oxigenoterapia hiperbárica e implantes dentales. Estos procedimientos combinados permitieron la extirpación de la lesión y el restablecimiento del contorno y la función mandibular.

ABSTRACT

Osteomas são tumores benignos compostos de osso maduro compacto ou esponjoso, podendo apresentar-se clinicamente na periferia, intraósseo, ou no interior dos tecidos moles. São essencialmente restritos ao esqueleto craniofacial, ocorrendo com maior frequência na mandíbula, sendo raramente diagnosticados em outros ossos. A variável osteoma periférico apresenta-se como uma massa óssea pediculada, de crescimento lento, assintomática, isolada e unilateral. Sua frequência é maior em homens, entre a segunda e quinta décadas de vida, sendo sua etiopatogenia amplamente discutida, podendo ser de origem reacional, traumatológica, inflamatória, ou alteração na fisiologia óssea. Comumente esta lesão está associada a pacientes portadores da Síndrome de Gardner. Objetiva-se, através de relato de caso clínico, discutir a causa, aspectos clínicos, radiográficos e histológicos desta neoplasia, assim como seu tratamento.


Osteomas are benign tumors composed of compact or cancellous mature bone, which may present clinically in the periphery, intra-bone or inside soft tissues. They are essentially restricted to craniofacial skeleton, occurring more frequently in the jaw, rarely diagnosed in other bones. The variable peripheral osteoma usually presents as a pedicled bone mass, of slow growth, asymptomatic, isolated, and unilateral. It is more frequently found in men, between the second and fifth decades of life, being its etiopathogenesis widely discussed, its origin may be reactive, inflammatory, from trauma or physiological bone changes. These lesions are commonly associated with patients with GardnerÆs Syndrome. Through a case report this study aims to discuss cause, clinical, radiographic and histological aspects of this neoplasm, as well as its treatment.

ABSTRACT

El hemangioma intramandibular es una neoformación benigna que resulta de la proliferación anormal de vasos sanguíneos, de origen desconocido. Estos tumores, por lo general, son hallazgos radiológicos y se caracterizan por ser asintomáticos y/o presentar movilidad de los dientes afectados, asimetría facial, parestesias y dolor, entre otros síntomas. Después de las vértebras y el cráneo, la mandíbula esel sitio más frecuentemente afectado, sobre todo en su parte posterior.El propósito de este trabajo es presentar un caso clínico de esta enfermedadpoco habitual.


Intraosseous hemangioma of the mandible is a benign neoplasm that originates from the abnormal proliferation of blood vessels, the cause of which is unknown. In general, these tumors are detected by means of X-ray and are characterized as asymptomatic or presenting mobility in the affected teeth, facial asymmetry, paresthesia and pain, among other symptoms. After the vertebrae and skull, the most frequently affected site is the jaw, particularly the posterior part. The purpose of this paper is to present a clinical case of this rare disease.

Los hemangiomas son neoplasias benignas de origen endotelial, formadoras de vasos. Los hemangiomas intraóseos son condiciones raras que comprenden del 0.5 a 1% de todos los tumores intraóseos. Su localización más común es la columna vertebral y los huesos del cráneo. Aquéllos que se presentan en los maxilares son tumores muy raros. Dos tercios de éstos se localizan en la mandíbula, con una proporción de mujer a hombre de 2:1. El objetivo de este artículo es reportar un caso signifi cativo de un hemangioma central de grandes dimensiones de la rama de la mandíbula del lado derecho, el cual fuetratado exitosamente con resección quirúrgica y ligadura de vasos nutricionales. Caso clínico: Paciente de 14 años que presenta un área radiolúcida unilocular en la rama mandibular del lado derecho. Clínicamente se observa aumento de la cara difuso, que causa asimetría facialasintomática de tres años de evolución. Conclusiones: La importancia del hemangioma intraóseo de los maxilares radica en su proximidad con los dientes, lo que representa un alto riesgo de sangrado debido a cualquier traumatismo por intento de extracción. El diagnóstico de hemangioma intraóseo, debido a su baja incidencia e inusual manera de presentación, es un reto diagnóstico...

ABSTRACT

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm. It’s incidence approximately 1% of all oral tumors and 18% of all odontogenic tumors. More than 80% of cases of ameloblastoma occur in mandible. The ameloblastoma occurs in three variants solid or multicystic, unicystic, and peripheral. A painless expansion of the jaws is the most common clinical presentation. The correct diagnosis can be easily made with the help of plain X-rays and tissue biopsy. The standard management of ameloblastoma is marginal resection but sometimes a large tumor requires complete resection of affected part. Untreated tumors may lead to tremendous facial disfigurement, a severe malocclusion and pathological fractures of the jaw. Here we present a case of a young man with the chief complaint of facial asymmetry. The orthopantomogram of the patient was showing a multilocular radiolucency with Buccal and lingual cortical expansion. A diagnosis was made on the basis of the biopsy as multicystic ameloblastoma, and resection of the mandible was carried out. The mandibular primary reconstruction was done with avascular bilateral iliac crest bone graft. Long term prognosis showed satisfactory healing and good facial esthetics.

ABSTRACT

Fifty-two patients of ameloblastoma were operated with special emphasis on radiographic and histological appearance. The unicystic radiographico-histological [38] cases were managed conservatively with marsupialization followed by enucleation [Group A' 15 Patients] and enucleation with peripheral ostectomy [Group B' 23 Patients]. The radiographico-histological multicystic [solid] variety [Group C' 14 Patients] was treated aggressively by resection. In conservative treatment regimens Carnoy's solution was applied after enucleation of the tumour whereas, the patients of aggressive surgery were operated with minimum 5mm safety marginal clearance of the tumour. The recurrence rate with average four years follow up was 0.0% for resection, 13.33% for marsupialization followed by enucleation and 8.69% for enucleation with peripheral ostectomy. The results were encouraging for unicystic ameloblastoma treated patients [Group A' and B'], in best interest of jaw bone contour preservation
