The challenges of reconstruction and rehabilitation of atrophic jaw with an autogenous graft from skull cap ­ a case report / Os desafios da reconstrução e reabilitação de mandíbula atrófica com enxerto autógeno de calota craniana ­ relato de caso

Introduction: One of the challenges of maxillofacial surgery is the rehabilitation of patients with severe bone loss, using implant-supported prostheses. This challenge is based on the small remaining bone structure, and on the need to reconstruct the structure for the rehabilitation with autogenous or exogenous grafts. Case report: We report the case of a patient with severe maxillary atrophy, where a skullcap graft was performed associated with implant placement and prosthetic completion 14 months after the start of treatment. Final considerations: We demonstrate clinical safety for the use of extraoral grafts without complications, representing a good alternative treatment for this group of patients.

Introdução: um dos desafios da cirurgia bucomaxilofacial é a reabilitação de pacientes com perda óssea severa, utilizando próteses implantossuportadas. Este desafio baseia-se na pequena estrutura óssea remanescente e na necessidade de reconstrução da estrutura para a reabilitação com enxertos autógenos ou exógenos. Relato de caso: Relatamos o caso de um paciente com atrofia maxilar grave, onde foi realizado enxerto de calota craniana associado à instalação de implante, com finalização protética 14 meses após o início do tratamento. Consideracoes finais: Demonstramos segurança clínica para o uso de enxertos extrabucais sem complicações, representando uma boa alternativa de tratamento para este grupo de pacientes.

Oral and Oropharyngeal Reconstruction with a Free Flap

Extensive surgical resection of the aerodigestive track can result in a large and complex defect of the oropharynx, which represents a significant reconstructive challenge for the plastic surgery. Development of microsurgical techniques has allowed for free flap reconstruction of oropharyngeal defects, with superior outcomes as well as decreases in postoperative complications. The reconstructive goals for oral and oropharyngeal defects are to restore the anatomy, to maintain continuity of the intraoral surface and oropharynx, to protect vital structures such as carotid arteries, to cover exposed portions of internal organs in preparation for adjuvant radiation, and to preserve complex functions of the oral cavity and oropharynx. Oral and oropharyngeal cancers should be treated with consideration of functional recovery. Multidisciplinary treatment strategies are necessary for maximizing disease control and preserving the natural form and function of the oropharynx.

Tunnelized-facial Artery Myomucosal Island Flap (t-FAMMIF) for Palatomaxillary Reconstruction: A Report of Two Cases

Use of the pedicled buccal fat pad in the reconstruction of intraoral defects: a report of five cases

The buccal fat pad is specialized fat tissue located anterior to the masseter muscle and deep to the buccinator muscle. Possessing a central body and four processes it provides separation allowing gliding motion between muscles, protects the neurovascular bundles from injuries, and maintains facial convexity. Because of its many advantageous functions, the use of the buccal fat pad during oral and maxillofacial procedures is promoted for the reconstruction of defects secondary to tumor resection, and those defects resulting from oroantral fistula caused by dento-alveolar surgery or trauma. We used the pedicled buccal fat pad in the reconstruction of intraoral defects such as oroantral fistula, maxillary posterior bone loss, or defects resulting from tumor resection. Epithelization of the fat tissue began 1 week after the surgery and demonstrated stable healing without complications over a long-term period. Thus, we highly recommend the use of this procedure.
