In-and-out Technique: An In-house Efficient Predictive Hole Fabrication Workflow.

Virtual surgical planning (VSP) and three-dimensional (3D) printing can increase precision and reduce surgical time in craniofacial reconstruction. However, the elevated cost and manufacturing time of outsourced workflows is increasing the development of in-house solutions. One of the main challenges in in-house workflows is to create cutting guides that hold plate position information. This is due to the fact that hospitals usually lack the infrastructure required to design and 3D print custom-made plates. Including plate-positioning information in resection guides is especially relevant in complex reconstructions and when tumor extension limits plate placement before resection. Current in-house workflows revolve around the idea of 3D scanning the bent plate's shape and to fuse it with the VSP. The goal of this article is to share our technique to transfer plate position information to resection guides. Our protocol uses a 3D model of the reconstruction as an intermediate step to transfer the plate position of a bent stock reconstruction plate to cutting guides. Two patients who required mandibular reconstruction with fibula flap are presented to illustrate the technique. This workflow requires a 3D-printed model of the desired outcome, cutting guides, and a stock plate. Results were satisfactory in terms of cutting location and angulation, plate adaptation and condylar position. This technique allows for a simple, safe, cheap, and quick alternative to add reconstruction plate information to cutting guides.

Tumoración intraoral con extensión inframilohoidea. Un hallazgo poco frecuente / Mass on the floor of the mouth with neck extension. An uncommon finding

Se presenta el caso de una paciente mujer de 67 años que acudió al Servicio de Urgencias del Hospital Universitario 12 de Octubre derivada de otro centro por sospecha de un absceso cervical de origen odontogénico. Sin embargo, la exploración física sugería una glándula sublingual herniada hacia el espacio submental y el TC informaba de una imagen en reloj de arena, pero el resultado histopatológico no fue ni de ránula sublingual ni de quiste dermoide. A propósito de este caso, se ha llevado a cabo una revisión bibliográfica de las lesiones frecuentemente encontradas en el suelo de la boca y la región cervical

A 67-year-old woman attended the Emergency Care Unit at 12 de Octubre Hospital with the suspicion of an odontogenic abscess diagnosed in another hospital. She presented with pain at lower left canine and growing submental mass. However, clinical examination suggested a plunging ranula and CT scan showed a "clock sand-like" image which is typical in dermoid cysts. Anatomic pathology confirmed that the mass was a lymphangioma. A literature review has been done to understand and differentiate masses that can be found in this region
