RESUMEN
Background: This study aims to present a case of deep cervicofacial abscesses and demonstrate the efficacy of CT-guided drainage with a custom-designed puncture guide in a challenging anatomical location. The use of this type of guide is an innovative technique since CAD-CAM technology has not been used for this type of application until now. Material and Methods: A 76-year-old man with persistent facial swelling and trismus underwent surgical drainage initially, but symptoms persisted. A CT-guided transcutaneous approach was planned using a custom-designed positioning guide created with "in-house" 3D technology. The guide was fabricated using Surgical Guide resin, and the patient underwent successful CT-guided drainage. Results: The intervention facilitated precise drainage without damaging critical anatomical structures. The patient exhibited prompt clinical improvement, shortened hospitalization, and favorable aesthetic outcomes. Conclusions: CT-guided drainage, particularly when combined with a custom puncture guide, offers a less invasive alternative for challenging cervicofacial abscesses. This approach proves valuable in reducing procedure duration, minimizing soft tissue trauma, and enhancing preoperative planning, making it especially beneficial for patients with high anesthetic risk or complex anatomical considerations. Key words:Cervical abscess, 3D technology, drainage guide, percutaneous puncture.
RESUMEN
Solitary fibrous tumor (STF) is a mesenchymal tumor that mainly appears in the pleura. Its presence in the oral cavity is very uncommon, being the buccal mucosa the most frequent location. Imaging cannot distinguish this entity between other types of tumors, being histological and immunohistochemical studies essential for its diagnosis. Immunohistochemical stains typically show positive results for CD34, Bcl2, and CD99. Surgical removal with wide margins is the gold standard treatment, requiring a close follow up due to recurrence risk. We present a case report of a solitary fibrous tumor located in the buccal cheek mucosa and the surgical approach. Key words:Solitary fibrous tumor, Buccal mucosa, Intraoral, Immunohistochemical markers.
RESUMEN
The soft tissue outcome of the projection at the level of the nasomaxillary buttress is difficult to manage in cases of severe hypoprojection, being orthognathic surgery resolutive at the occlusal level but sometimes insufficient at the level of esthetic outcome. The literature describes the use of alloplastic prostheses and autologous bone grafts, but there are few documented cases of the use of premolded surgical cement for this purpose. The main advantage of the use of bone cement over the alternatives described is its ability to be premolded for customization, low cost, easy availability, speed of preparation and minimal comorbidity. This technical note describes the surgical steps and outcome of the use of surgical bone cement for projection augmentation at this level, including notes on preparation, premolding and fixation. Key words:Orthognathic surgery, maxillary surgery, surgical bone cement, nasomaxillary buttress.
RESUMEN
El uso de la planificación virtual ha demostrado en varios estudios una mayor predictibilidad de los resultados quirúrgicos, así como una reducción del tiempo quirúrgico y la posibilidad de comparar nuestros resultados con los esperados mediante una comparación con un TC postoperatorio. En esta nota técnica se describe cómo planificar de forma virtual la cirugía mediante tecnología 3D in house de fracturas en mandíbulas atróficas usando un software de uso libre. (AU)
The use of virtual planning has demonstrated in several studies greater predictability of surgical results, as well as a reduction in surgical time. In addition, we have the possibility to compare our results with the planning through a comparison with a postoperative CT. This technical note aims to describe how to plan surgery for fractures in atrophic mandibles using pre-surgical 3D technology and a free software. (AU)
