RESUMO
Introduction: The chin is one of the most visible facial structures. Chin surgery, was initially described, for, the treatment of facial abnormalities, advancing the mandibular symphysis; achieved anterior displacement of the base of the tongue showing some value in the treatment of snoring and obstructive sleep apnea, and achieved adequate lip competence. We designed the Basal Extended Mentoplasty (BEM) based on the needs of patients orthodontically compensated, but dissatisfied with the appearance of his face as well as upper airway problems looking for a solution to this, design and planning the advances of the chin. Materials and Methods: Patients operated in the service of Maxillofacial Surgery, Specialist Hospital, "Dr. Bernardo Sepulveda "XXI Century National Medical Center, during the period of 2015-2019, orthodontically compensated patients, with labial incompetence and Class II skeletal. Sixty-five patients were operated during this period, and eight cases are presented. Results: Lip competition, osseointegration of the segments is observed, with a proper projection of the lower third, no nerve or vascular damage in the area. Conclusions: The design of the osteotomy is for orthodontically compensated patients with labial incompetence and Class II skeletal, giving a result mandibular lengthening. The BEM achieved adequate lip competence demonstrated by an interlabial gap of 0 mm, achieved adequate osseous consolidation of the fracture site with a more harmonious facial balance and profile, without nerve or vascular damage with spectacular results.
RESUMO
Background: Temporal muscle has great versatility to cover defects, caused by resections or large soft tissue losses of the middle facial third, has been used for more than 100 years. In the skin, the temporal muscle is transformed by the phenomenon called skin dermalization and mucolization in the oral cavity. Purpose: This article shows how the temporal muscle is divided into two segments (bipartition) or three segments (tripartition) achieving a transposition of the muscle to cover large empty spaces caused by orbital exenteration or in maxilectomy. In coronal slice tomography, we demonstrate the perfect adaptation of the temporal muscle to the periorbital soft tissues in 360 degrees of the orbital region. In the defect produced by the maxilectomy, a perfect seal is obtained to achieve the separation of the nasal cavity from the oral cavity. Methods: The treatment was carried out in 3 immunocompromised adult patients, who presented mucormycosis of the middle third of the face and could not swallow or feed. Results: The result we have in the survival of rhinocerebral mucormycosis is very high, due to extensive resections. Achieving that the patient has an adequate swallowing. Conclusion: We consider that the treatment is excellent due to the proximity of the temporal muscle to the surgical defect, achieving the objective of reconstruction without rejection.
RESUMO
Se presenta el manejo quirúrgico para el dolor de la articulación temporomandibular (ATM) como la mejor alternativa de tratamiento cuando los desórdenes internos articulares alcanzan rangos de dolor moderado y grave. Se describe la técnica retroauricular modificada sin sección del conducto auditivo externo que representa un método seguro y eficaz para abordar la ATM y controlar en forma definitiva la sintomatología. El éxito de este tratamiento ha sido comprobado en 118 casos operados de enero de 1990 hasta octubre de 1992.
