Mandibular osteoma in the posterior margin of the mandible: A literature review and case reportSebastián Lazo R Diego Ramirez V Felipe Astorga M -
Osteoma is a benign bone tumor that can develop in bones throughout the entire body but occurs mainly in the craniofacial bones. It presents as a proliferation of medullary or cortical bone, and can be classified as cen- tral, peripheral, or extra skeletal. The appearance in the jaws is infrequent, but when it occurs, there is a greater predominance of the mandible. The etiology is still unknown and the hypothesis of its development is debated, since it can occur as a reaction to trauma or infection, or originate as a true neoplasm. Osteomas of the jaws mostly present as a well-defined hyperdensity on computed tomography scans. This article presents a 49-year-old patient, where a case of a peripheral osteoma at the level of the inner face of the condyle of the left temporomandibular joint, which was related to the ipsilateral styloid process and generated complications in swallowing the patient. Two years ago, due to a radiographic finding, a radiopaque asymptomatic mass was investigated in the left mandible and was kept under observation. It progressed, increasing in volume, causing swallowing problems. In this case, we show the clinical, radiographic, scanner, Angio Tac and histopathological findings are included, in addition to the programs used to plan the resection of the osteoma.

Analysis of biomimetic strategies for surface conditioning of dental implants: a literature reviewPaula Castro C. Juan Pablo Parrochia S. José Valdivia O. -
It has been seen that enhancing the characteristics of the surface of an implant with bioactive agents that seek to mimic the chemical and biological nature of native bone can influence osseointegration. This article seeks to describe biomimetic treatment strategies for dental implant surfaces that favor the bioactivity of implant materials. The search was performed in PUBMED and the Cochrane Library with the terms “biomimetic dental implants” or “biomimetic implants” obtaining 110 results. After analyzing each reference, it was determined that 11 articles coincide with the objective of this review, they provide data from ex- perimental studies, reviews, and clinical cases on different biomimetic strategies for surface treatment. Within the surface conditioning strategies with chemical substances, it is described that sandblasting and acid etching favor biocompatibility, cell differentiation and bone formation. Also, the use of coatings that allow the composition of the implant surface to approach the na- tural characteristics of bone tissue is favorably described. On the other hand, based on a biomimetic approach, implant surface coatings with different biomolecules such as growth factors, extracellular matrix proteins, peptides and drugs are described, with the constant objective of promoting osseointegration. Although studies indicate that implant surface treatments favor the osseointegration process, it is necessary to investigate mostly the use of biomolecules that combine the implant surface with the host environment.

Virtual planning previous surgery first approach: a case reportXimena Toledo Ilich Vargas Felipe Soto Paola Berdeja Rodrigo Fariña -
Orthognathic surgery consists of a procedure that can be divided in two phases; an orthodontic phase destined to correct dental position and occlusion, and a surgical phase which resolves the individual’s skeletal condition. In the conventional manner, the sequence begins with the orthodontic phase, occlusally decompensating the patient thus altering patients’ aesthetics throughout this period. Based on this conflict, the Surgery First Approach (SFA) has been proposed, beginning with the surgical phase and therefore performing the orthodontic phase in a second instance. This article presents the planning sequence carried out through virtual 3D softwares regarding a singular SFA case. Regarding obtained results and data collected from available evidence, SFA technique is a valid alternative in orthognathic surgery that relies on a series of steps to be followed and interdisciplinary communication in order to achieve satisfactory and accurate results both for patient and practitioners, with a lesser aesthetical and psychological compromise.

Simultaneous use of double Struts for unsupported noses: technical notePaolo Verona Liseth Chacón Nicolas Solano Patricia López -
Rhinoplasty is the most practiced facial aesthetic procedure in the world and has generated enormous literature on the matter. The objective of this study is to describe the use of the simultaneous double strut technique for unsupported noses. Currently the anterior strut does not need a great length, nor does it need to be fixed to the SNA, just as it will not be in charge of providing projection to the nasal tip, it is enough to fix it to the medial cruras to provide greater support to the nasal tip. the technique Teo strut, is in charge of giving projection as well as the support to the nasal tip. The Teo Strut technique possible to provide support and stability to the nasal projection, rotation of the nasal tip, and adequate points of light and shadows in the different polygons, maintaining principles of preservation in some cases, thus reducing fibrosis and healing action, giving lasting results in the time.
KEY WORDS: Unsupported noses, rhinoplasty, Teo Strut, reconstruction.

Intravascular papillary endothelial hyperplasia in the lower lip: A case reportFreddy Rodríguez Dario Sosa Alexei Rojas Mariana Villarroel-Dorrego -
Intravascular papillary endothelial hyperplasia or Masson’s tu- mor is a benign, non-neoplastic lesion that can affect the torax, fingers, head, and neck. Its presence in the oral cavity is unusual; however, there are reports in the literature. A female patient in the 4th decade of life who attended the Oral and Maxillofacial Surgery Department of the Universidad Central de Ve- nezuela, with a purplish lesion on the lower lip of two months of evolution associated with masticatory trauma is presented. An excisional biopsy was performed, and a histopathological study was performed. The wall of blood vessels made up of endothelial cells showing intraluminal papillary growth was observed. The papillary structures are lined by hyperplastic endothelial cells in the vascular lumen. The definitive diagnosis was intravascular papillary endothelial hyperplasia. Due to the great resemblance to other vascular lesions, it is essential to perform a histopathological study of suspicious lesions to rule them out.
KEY WORDS: Endothelial hyperplasia, Masson’s tumor, benign oral lesions.

Extreme facial rejuvenation, the combination of orthognathic surgery and cervico-facial rhytidectomyPaolo Verona Federico Hernández-Alfaro Abraham Montes de Oca Nicolás Solano Liseth Chacón Ejusmar Rivera Patricia López -
Multiple adjunctive procedures are performed with orthognathic surgery to enhance aesthetic facial results, especially in those cases where skeletal movements alone do not satisfy the aesthetic demands of the patient. The objective of this study is demonstrate the benefits and outcomes of performing orthognathic surgery and cervicofacial rhytidectomy simultaneously to achieve extreme facial rejuvenation. Two clinical cases with a diagnosis of cervicofacial rhytidosis and dentoskeletal anomalies are shown, the first case with retrogeny and superior dermatocalasia and the second case with class III dentofacial anomaly and retrogeny, which were treated with the combination of orthognathic surgery and cervicofacial rhytidectomy in the same operative act. Facial aesthetic surgery has evolved by recognizing that changes in hard tissues affect soft tissues, however its isolated resolution does not meet the final aesthetic expectations of the patient in soft tissues. That is why there is a need to combine simultaneous procedures to meet the needs for which the patient comes and maintain the results over time. All patients who decide to undergo surgery for aesthetic reasons must also improve function. And due to the increase in operative time that carries out both surgeries simultaneously must be performed by a well-trained maxillofacial surgeon.
KEY WORDS: Aesthetic surgery, orthognathic surgery, rhytidectomy, rejuvenation protocol, dentoskeletal anomalies.

Treatment of superficial benign parotid tumors a the Libertador regional hospital Bernardo O’Higgins de Rancagua, Chile: 5-year experience and analysisPedro Tapia Gustavo Matus-Miranda Pablo Molinare Ricardo Sepúlveda -
Parotid gland tumors correspond to 70 – 80 % of salivary gland tumors. Approximately 80% of them are benign and the majority appear in adults. These tumors are characterized by a great diversity in their histopathological characteristics. The main complementary tests are computed axial tomography, magnetic resonance imaging, and ultrasound- guided fine needle aspiration. The treatment of benign tumors of the parotid gland is surgical and the type of resection is the subject of debate in the literature, as it varies between wide excision techniques, such as total parotidectomy, partial superficial parotidectomy of the facial nerve, and less severe procedures. invasive procedures such as transparotid excision and extracapsular dissection. The objective of this work is to present the experience of the Maxillofacial Surgery team at the Rancagua Hospital in the surgical resolution of benign neoplasms of the parotid gland with a 5- year retrospective review. An interdisciplinary preoperative evaluation was carried out between teams of Maxillofacial Surgery, Maxillofacial Pathology and Head and Neck Surgery with imaging, serological and FNAC examinations. Of all the tumors biopsied, the benign parotid neoplasms were referred to Maxillofacial Surgery for surgical resolution. Most of these tumors were operated on with preauricular approaches with mandibular subangular extension and extracapsular dissection. The patients presented few post-operative complications, with a low rate of lesion recurrence, considering a conservative surgical treatment compared to superficial parotidectomies, which is a more aggressive and widely used therapeutic alternative. This type of minimally invasive intervention is an effective alternative with a low recurrence rate and minimal postoperative complications. It is worth highlighting the importance of the Maxillofacial Surgery specialty within medical, surgical, and oncological work teams in the resolution of this type of facial neoplasms.

Relationship between anterior crossbite, growth pattern and mandibular development: A narrative reviewConstanza Paz Lillo Fritz Valentina Arlette Morales Ahumada Constanza Paz Lillo Fritz Valentina Arlette Morales Ahumada Torres Lefián Torres Lefián -
During the process of growth and development of children, multiple structural changes occur in the facial skeleton, wich are closely related to habits, functions, and individual genetics, among other factors. When an anterior crossbite develops it alters the function of the stomatognathic system, and possibly affects the facial growth pattern and normal jaw development. The objective of the present narrative review is to relate the facial growth pattern in children with anterior crossbite and how it influences in mandibular development.

Modification of the intermaxillary fixation technique in patients treated with aligners a case reportXimena Toledo Felipe Soto Paola Berdeja Rodrigo Fariña -
The use of clear aligners in patients undergoing orthognathic surgery constitutes an alternative to conventional orthodontic-surgical preparation, presenting certain advantages such as comfort, aesthetics, lower cost and surgical time reduction. The objective of this article is to present, regarding a case, a clear aligner modification applied to surgical orthodontics, which allows intermaxillary fixation (IMF) without resorting to the installation of microimplants. Based on our findings, we can affirm that the modification of the technique presented is capable of providing satisfactory and stable long-term results in a surgical context, presenting numerous advantages with respect to the use of conventional fixed appliances.
KEY WORDS: Orthognathic surgery, clear aligners, intermaxillary fixation, surgical splints.

Surgical management and follow-up of custom implant treated orbito-zygomatic fracture: case report and literature reviewGonzalo Martinovic Paz Martínez Gastón Salas Felipe Soto Sofía Escobar -
Orbital floor fractures are common injuries in the maxillofacial region, typically caused by blunt trau- ma. Clinical manifestations involve facial asymmetry, enophthalmos, diplopia, and restricted ocular motility. These fractures can be treated by either conservative or surgical approaches. We present the case of a 59-year- old patient with a history of orbitozygomatic fracture, resulting from a car accident, treated using a custom- made polyetheretherketone (PEEK) implant at the Hos- pital Militar de Santiago. Using virtual planning software and 3D printing technology, a PEEK implant was designed and positioned via a transconjunctival approach. Long-term follow-up showed favorable evolution without loss of visual acuity and evidence of bone regeneration at five years. This case highlights the advantages of PEEK in orbital reconstruction, including its adaptability and biocompatibility, while acknowledging challenges such as cost and infection risk, underscoring its potential in modern maxillofacial surgery.
