Osteomielitis crónica no supurativa mandibular: reporte de caso
(2022) Castillo Yaguana, Darwin Vicente; Cazar Almache, Marcelo Enrique; Torres Calle, María Fernanda; Pinos Gavilanes, María Paz
Osteomyelitis (OM) is considered one of the most challenging medical conditions for surgeons. In the last 50 years the number of cases of maxillary OM has decreased due to an improvement in oral hygiene, however, its complication is still relevant. The purpose of this paper is to present a case report of a patient with mandibular osteomyelitis and to analyze the literature on this condition
Tratamiento de quiste óseo traumático mandibular de grandes dimensiones. Revisión de la literatura y reporte de un caso / Treatment of a Large Mandibular Traumatic Bone Cyst: Literature Review and Case Report
(2012) Cazar Almache, Marcelo Enrique; Miranda Villasana, José Ernesto; Brau Figueroa, Adrián; Recendez Santillán, Norith de Jesús
Background: The traumatic or simple bone cyst is frequently found in the maxillofacial area mostly in the posterior body of the mandible; its average diameter is 1-3 cm and the usual treatment is bone curettage. Method: A review of literature and a case of a large mandibular traumatic bone cyst are presented. An alternative therapy to treat large pseudocysts is proposed. Results: A 19-year-old female patient with diagnosis of a large simple bone cyst (diameter: 10 cm) was treated at the Regional “Vicente Corral Moscoso” Hospital that is affiliated to the Ministry of Health of Ecuador. The treatment consisted of intracavitary curettage and autologous iliac crest bone graft, achieving a fast and adequate bone mandible reconstruction.
Determinación de estándares cefalométricos de las diferentes etnias de Ecuador
(2016) Piña Cortés, Victor Alejandro; Cazar Almache, Marcelo Enrique; Miranda Villasana, José Ernesto; Bravo Calderón, Manuel Estuardo
Cephalometry with lateral skull radiography is a routine diagnostic method in orthodontic and maxillary orthopedic practice that under the metric problems and previously established proportions, establish an important part of the diagnosis in skeletal cephalic alterations called dentofacial deformities; The criteria specified above correspond mostly to the measures taken by Caucasian individuals, so it does not coincide with the exact average of the measures of the rest of the ethnic groups. Through this study, a representative sample of the Ecuadorian population, with its different ethnicities, was taken to establish the arithmetic mean of its craniofacial measures and proportions, so that it is counted on the one that represents the normality of each representative ethnic group of Ecuador . The estimate of the population sample consists of 30 individuals by ethnicity from 18 to 30 years of age, without previous aesthetic, reconstructive and / or craniofacial symptoms, maxillary orthopedic appliances, traumatic or syndromic sequelae diagnosed. This population will perform a lateral skull x-ray that will then be quantified with Ricketts Cephalometric analysis by means of Dolphin® software, obtaining through arithmetic average statistical tools and standard deviation of measurements and proportions by ethnic group with the program SPS®; The ethnicities to study will be: white, mestizo, Afro-Ecuadorian and indigenous.
Queratoquiste Odontogénico de amplia dimensión: reporte de caso
(2020) Cazar Almache, Marcelo Enrique; Torres Calle, María Fernanda; Pinos Gavilanes, María Paz; Castillo Yaguana, Darwin Vicente; Cárdenas Campoverde, Juan Diego
Odontogenic keratocyst (OKC) is a lesion which origin is the dental epithelium,it has a predilection for presenting itself in the posterior portion of the mandible and is considered one of the most common lesions within odontogeniccysts. The following study presents a case of Odontogenic Keratocyst of a large dimension. A female patient presents with inflammatory symptoms at the level of the jaw. In the intraoral physical examination a palpation test was performed and together withradiographic examinations, in which a multilocular radiolucent image of 8x3 cm was determined. Subsequently, a biopsy was performed and the histology was compatible with Odontogenic Keratocyst. This article reviews the etiopathogenesis, clinical, radiographic, histopathological, immunohistochemical and treatment; with the aim of describing the importance of this lesion due to its ability to reach large dimensions and present high recurrence. Therefore, it is important to make a correct diagnosis that allowsto establish an adequate treatment plan for this lesion
Precisión diagnóstica de la tomografía volumétrica de haz de cono en terceros molares impactados en relación con el canal mandibular. Revisión de la literatura."
(2022) Marcatoma Guamán, Luis Alejandro; Parra Martínez, María Gabriela; Cazar Almache, Marcelo Enrique
This review aimed to determine the diagnostic accuracy of cone beam volumetric tomography compared to panoramic radiography of impacted third molars, in relation to the mandibular canal at the time of surgery and to avoid postoperative complications. A bibliographic review of the different studies published in the scientific database PubMed was carried out; Articles from the last twelve years were taken into consideration. Articles were selected using inclusion and exclusion methods, collecting a total of 16 English-language articles for final study analysis. The CBCT showed more evidence of the close relationship between the impacted third molars, the nerve and the mandibular canal, in contrast to the RP. CBCT presented greater sensitivity, being considered the radiographic examination of first choice in complex cases to avoid postoperative complications. CBCT is the optimal method to clarify the relationship that exists between the lower third molars and the CM, in a unit of measure and thus develop surgical guides for the different treatments
Manejo quirúrgico de la hiperplasia condilar tipo 2: reporte de un caso
(2019) Barajas Pérez, Victor Hiram; Cazar Almache, Marcelo Enrique; Miranda Villasana, José Ernesto; Recendez Santillán, Norith De jesús; Cuevas González, Juan Carlos; Zambrano Galván, Graciela
Condylar hyperplasia (CH) is a generic term for a pathological situation that is used to describe conditions that cause excessive growth and overdevelopment of the mandibular condyle and also impacting on the jaw, this bone formation is responsible about of 50 % of all deformities facial and it occurs most frequently between 11-30 years old. This case report is about a 21-years old female who showed unilateral condylar hyperplasia of left side with alveolodentary compensatory. Was carried out high condilectomy through an endoaural approach removing 5 mm of the upper condyle and the mandibular osteotomy was performed through intraoral approach with dissection and preservation of the inferior alveolar nerve, removing 8 mm of the inferior aspect of the mandible according to the aesthetic requirements. An appropriate treatment for the condylar hyperplasia focused on correcting the side effects such as functional or aesthetic it’s of great benefit for the patient because it allows improve their quality of life. A correct diagnosis is very important to planning a successful treatment.
Seguridad en la colocación de mini implantes ortodónticos en la región infracigomática
(2015) Cruz Ibañez, Luis Arturo; Gualan Cartuche, Leonardo Patricio; Cazar Almache, Marcelo Enrique; Bravo Calderón, Manuel Estuardo; Miranda Villasana, José Ernesto
Knowledge of the anatomy of the anterolateral region of the maxillary sinus should be essential when orthodontic mini screw implants are placed in the maxilla region. A retrospective study is performed to analyze the location of the alveoloantral artery in 158 Cone beam computed tomography (CBCT) studies of a population the city of Cuenca Ecuador. The distance was measured between alveoloantral canal and the cervical region from the first premolar to the second molar bilaterally. Thus the average measurements of the location of said vascular package level above the dental organs being determined that the length of the miniscrew implants to be placed in the region of infracigomatic crest be exceeded 15 mm were established

(2020) Vega Zamora, Oswaldo Francisco; Da Costa Moraes, Cicero André; Pacheco Merchan, Maria Belen; Espinoza Mejía, Jorge Mauricio; Cazar Almache, Marcelo Enrique
Cone Beam Computed Tomographs (CBCT) provide high-quality 3D images with submillimeter resolutions, fairly short scantimes (10 to 70 seconds) and radiation doses up to 15 times lower than classic CT systems. Thanks to this, its use in differentareas, both in dentistry and in other areas, has increased significantly. Additionally, the advancement of teleradiology and thecompatibility of the resulting DICOM images with different types of planning, simulation and 3D printing software; have madeit possible to consolidate a powerful tool for the possible early and accurate diagnosis of different deep lesions, anomalies andthe acquisition of deep knowledge about a specific maxillofacial area and its relationship with adjacent structures. However,its resulting measurements with very little error range and the possibility of generating three-dimensional reconstructionsmake it a clear pedagogical instrument of great utility in modern archaeological, technological, forensic, anthropologicaland biomedical investigation techniques. This article provides an overview of CBCT systems, their associated computationaltechnologies, and demonstrates their applicability as tools for the analysis, preservation, reconstruction and reproduction ofarchaeological pieces. As a test, its application in the acquisition of different stereolithographic models of archaeologicalremains of the Pumapungo Museum in the city of Cuenca, Ecuador is described
Rotación del cuerpo adiposo de la mejilla para aumento de la proyección labial: reporte de caso
(2016) Cazar Almache, Marcelo Enrique; Palacios Vivar, Diego Esteban; Miranda Villasana, José Ernesto
The treatment of patients with skeletal abnormalities or deformities begins with planning based on facial analysis and cephalometric tracing. Often the values obtained from that analysis reveal abnormal skeletal conditions or insuffi cient soft tissue. Autologous fat grafts and using the buccal fat pad provide viable options to correct these defects and achieve a favorable aesthetic and functional result. The tissue characteristics of the buccal fat pad make it a structure that has good adaptability and a low rate of infection and rejection. It is often overlooked and simply resected to achieve more defi ned cheekbones and facial contours. It has multiple therapeutic uses and should always be considered an option in reconstructive procedures. We present the case of a 17-year-old female patient diagnosed with a dentofacial deformity, soft tissue defi ciency in the lip and perinasal region, and a failed orthodontic camoufl age treatment. Orthognathic and rhinoplasty surgery were performed to correct the hard-tissue defect, and the buccal fat pad rotated and advanced to enhance soft-tissue projection.
Tumor pardo maxilar: reporte de caso
(2019) Abril Cordero, Luz Marina; Cazar Almache, Marcelo Enrique; Espinoza Soto, Pedro Esteban; Palacios Vivar, Diego Esteban; Cañar Rivera, Gabriela Elizabeth
Introduction: Brown tumor is a rare pathology resulting from uncontrolled hyperparathyroidism, which produces areas of localized bone destruction. They are present at the facial level in the mandible and maxilla, ribs, clavicle, pelvic waist and upper and lower extremities. Its name is given by the pigmentation of the extravasation of blood and hemosiderin to the tumor. It can manifest itself in any decade of life. Has greater predisposition in women of the fourth and fifth decade of life. Its presence at the level of maxillary bones requires a complex system of studies and multidisciplinary management for diagnostic confirmation and treatment. Clinical case: The case of a 36 year old patient with no personal or family history is reported. She comes by referral for placement of a bone graft for dental mobility. In the image evaluation, there is a right radiolucent zone in the body of the mandible, in relation to the teeth. The lesion usually presents as a well-delimited unilateral or multilocular radiolucent area; another important radiographic finding in hyperparathyroidism is the absence of hard laminae around the dental organs. Conclusions: The brown tumor should be considered as a differential diagnosis of mandibular tumors due to the fact that not every tumor has a primary etiology
