“…5,1,4,6 En este caso se realizó la resección completa con márgenes de seguridad de las lesiones, más la colocación de una placa de reconstrucción a través de un abordaje extraoral, se decidió por un tratamiento agresivo debido a la alta tasa de recurrencia del ameloblastoma y del fibroma osificante, y a los 6 meses posterior a la cirugía no se evidenciaron recidivas. 7,4,6,8,5,14 Este es el primer caso reportado en la literatura en el cual se presenta de forma simultánea en la misma hemimandíbula un fibroma osificante y un ameloblastoma, esta combinación puede deberse a la casualidad como lo describieron Hosseini y…”

“…El tratamiento del ameloblastoma puede ser un problema debido a su alta taza de recurrencia con tratamientos conservadores, pero también hay que tomar en cuenta las complicaciones de un tratamiento agresivo y las técnicas reconstructivas que se pueden utilizar. 7,4,6 El fibroma osificante (FO) fue descrito por primera vez en 1872 por Menzel en un paciente femenino de 35 años de edad, la cual presentó un tumor en la mandíbula. Desde entonces el (FO) ha sido reclasificado dentro de diferentes categorías.…”

El ameloblastoma, así como el fibroma osificante son dos de las lesiones más comunes de los maxilares de origen epitelial, que producen expansión local de los tejidos, ambos pueden aparecer entre la segunda y tercera década de la vida, son agresivas, de crecimiento lento, usualmente asintomáticas, aunque en raras ocasiones puede ser dolorosas, por lo que su diagnóstico clínico temprano es difícil, estas presentan una alta tendencia a la recidiva. Entre las características radiológicas el fibroma osificante se presenta como una imagen mixta bien definida separada del hueso circundante por un halo isodenso, mientras que el ameloblastoma se presenta como una lesión radiolúcida bien circunscrita unilocular o multilocular. El objetivo de este artículo es reportar el caso de un paciente en el cual se presentaron dos lesiones en una misma hemimandíbula.

“…The three changes in the classification of odontogenic keratocyst by WHO suggest that the peculiar characteristics of this lesion are of paramount importance for differential diagnosis and therefore, important to compose an adequate surgical treatment choice. 3,6,10,11 The KOC can manifest itself as unilocular or multilocular form. The unilocular form has similarities w it h t he unic yst ic a meloblastoma.…”

“…Thus, for these lesions there are different complexities to surgical management, sometimes there is a specific treatment. [9][10][11][12] Magnetic resonance imaging is a technique that has great ability to differentiate soft tissues Some studies, after confirming the lesions by anatomopathological examination, were directed to the purpose of performing a differential diagnosis of keratocysts through the use of magnetic resonance imaging. 8,[14][15][16][17] Thus, the aim of this study is to review studies that have applied magnetic resonance imaging as a tool for differentiating OKC from ameloblastomas.…”

Efficacy of MRI in the differential diagnosis of odontogenic keratocyst: literature review

et al. 2018

According to the World Health Organization (WHO 2017), the odontogenic keratocyst (OKC) is classified as an odontogenic developmental cyst, with origins from the cellular remnants of the dental lamina. The characteristics of a high rate of cell proliferation, relapse and aggressive growth guide the choice of the type of surgical treatment for the lesion and, consequently, the prognosis. The use of Magnetic Resonance Imaging (MRI) for the differential diagnosis of odontogenic lesions does not replace anatomopathological examination, but the types of protocols already described illustrate the influence of these different protocols on the qualitative and quantitative description of keratocysts. We conclude that magnetic resonance imaging is valid as a tool to aid diagnosis of odontogenic lesions, especially for differential diagnosis studies between odontogenic keratocysts and ameloblastomas.

“…15 However, there is a paucity of long-term studies that examine patient-reported function, determinants of quality of life, and complication rates to establish if this technique is indeed still a viable option in settings without access to microsurgery. [15][16][17][18][19] These data might help to promote the uptake of this method and improve the lives of patients with large ameloblastoma in LMICs.…”

Long‐term outcomes of mandibular reconstruction using non‐vascularised rib grafts following large ameloblastoma resection in Ethiopia

et al. 2021

Aim Ameloblastomas are odontogenic tumours that often require radical excision and mandibular reconstruction. This is challenging in resource‐limited settings where access to microsurgery is often scarce or absent. Currently, some patients are left without reconstruction, and others with bulky metal plates prone to complications. This leads to disfigurement and poor functional outcomes. We aim to establish robust long‐term outcomes for non‐vascularised autologous rib grafts for patients in this setting. Materials and Methods Twelve adult patients with large ameloblastomas underwent hemimandibulectomy and rib graft reconstruction during international surgical collaborations in Ethiopia between 2012 and 2015. A long‐term follow‐up was conducted in rural Ethiopia in February 2017. Results Follow‐up was possible for seven patients (58% of those treated). Mean post‐operative follow‐up time was 42.9 months (SD 11.7; range 24–60 months). Early complications were four superficial surgical site infections. Late complications were two cases of wire extrusion and one of keloid scarring. There were no graft failures. Patients reported reduced social stigma (p = 0.001) and pain (p = 0.03), excellent function and 100% satisfaction. Conclusion When situational factors preclude the use of microsurgery, bundle rib grafts offer a reliable alternative for total mandibular reconstruction for patients after ameloblastoma resection. Mild complications were experienced by most patients, but these were straightforward to manage and the rib grafts still took well, being surprisingly resistant to infection. Importantly, this technique is associated with long‐term improvements in social stigma and quality of life for patients.
