This study aimed to analyze the clinical applicability, surgical technique, and outcomes of the pedicled osteomyocutaneous pectoralis major flap, highlighting the joint involvement of the Head and Neck Surgery and Oral and Maxillofacial Surgery teams. An analysis was conducted of a series of four cases involving patients with advanced neoplasms, in whom oncologic resection and reconstructive planning assisted by prototyped biomodels (3D printing) were performed. The technical differential lay in the pre-molding of the reconstruction plate on the biomodel during the preoperative period, ensuring precise maintenance of the intercondylar distance and passive rigid fixation. Immediate reconstruction was performed using the pectoralis major flap with incorporation of a rib segment. The results demonstrated the vascular robustness of the technique and the effectiveness of preoperative planning, which optimized intraoperative time and ensured an anatomical reconstruction. Postoperative complications were managed conservatively, without compromising rib-to-mandible bone union. It is concluded that collaboration between the specialties, combined with technical refinement through biomodeling, makes the pectoralis major flap a safe, predictable, and essential salvage alternative for the functional and structural rehabilitation of high-complexity patients. 2026-01-07T00:00:00Z https://repositorio.ufu.br/handle/123456789/48108 Title: Planejamento virtual em implantes zigomáticos pós-trauma: relato de caso no SUS Abstract: Introduction: The rehabilitation of extensive maxillofacial defects resulting from high-energy trauma represents a significant surgical and prosthetic challenge, particularly in the presence of severe bone loss and complex anatomical alterations. Zygomatic implants constitute a predictable alternative, enabling oral rehabilitation without the need for bone grafting. This study aims to report the clinical case of a young female patient, a victim of a high-energy motorcycle accident, with severe maxillary destruction, rehabilitated with virtually planned zygomatic implants in a public healthcare setting. Case report: A 24-year-old female patient was referred from another service after initial management of comminuted maxillary and mandibular fractures, presenting with occlusal alterations and extensive tooth loss. Initially, occlusal correction was performed through mandibular osteotomy in the symphysis region. Subsequently, virtual surgical planning was carried out for the placement of zygomatic and conventional implants for maxillary rehabilitation. Zygomatic implants associated with conventional implants were placed using three-dimensionally printed surgical guides. The patient evolved without complications and is currently in the prosthetic finalization phase. Conclusion: Therefore, zygomatic implants associated with virtual planning constitute a safe, predictable, and viable alternative for the rehabilitation of severely traumatized maxillae. 2026-01-07T00:00:00Z https://repositorio.ufu.br/handle/123456789/48042 Title: Orthognathic surgery and temporomandibular disarrangement: a critical review of a complex relationship and two cases report 2026-01-07T00:00:00Z https://repositorio.ufu.br/handle/123456789/48041 Title: Abordagem Diagnóstica e Terapêutica do Carcinoma Adenoide Cístico: Relato de caso Abstract: Carcinoma Adenoid Cystic (CAC) is a malignant neoplasm of the salivary glands, being one of the most common salivary gland tumors, representing approximately 6 to 10% of all salivary carcinomas and among head and neck malignancies representing 1%. Clinically, it appears as a swelling or a tolerable nodule, with slow growth, invasive behavior and is more common in adults aged between 50 and 70 years. The most common treatment for this pathology is surgical resection with a safety margin, associated with radiotherapy, however the surgical procedure usually causes important structural deformities. The present work reports the oral rehabilitation of a male patient, 48 years old, diagnosed with CAC in the left maxillary sinus, who underwent partial maxillectomy, at the Hospital de Clínicas de Uberlândia, involving from the region of tooth 14 to the end of the contralateral maxilla. Due to the large oral defect caused by the surgery, lack of supporting tissue, including in the palate area, a rehabilitative intervention was necessary. To improve oral rehabilitation, it was necessary to install four osseointegrated implants in the maxilla, together with the creation of a metal crown on tooth 18, to support an integrated partial denture (PPR) associated with the clip bar system. The patient was irradiated and requested chemotherapy sessions. The treatment proposal aims to reestablish the functions of the stomatognathic system, restoring aesthetics, phonetics and chewing capacity, improving comfort and thus improving the patient's quality of life. After installation, weekly monitoring will be carried out for control. 2025-12-11T00:00:00Z
