Direct Integration of 3D Printing and Cryogel Scaffolds for Bone Tissue Engineering.

Cryogels, known for their biocompatibility and porous structure, lack mechanical strength, while 3D-printed scaffolds have excellent mechanical properties but limited porosity resolution. By combining a 3D-printed plastic gyroid lattice scaffold with a chitosan-gelatin cryogel scaffold, a scaffold can be created that balances the advantages of both fabrication methods. This study compared the pore diameter, swelling potential, mechanical characteristics, and cellular infiltration capability of combined scaffolds and control cryogels.

A Rare Presentation of Intraosseous Sarcoidosis of the Mandible Presenting as Peri-Implantitis: A Case Report and Literature Review.

We describe a rare case of intraosseous sarcoidosis initially presenting as peri-implantitis, perform a review and analysis of 27 cases of intraosseous sarcoidosis, and provide a clinical review of this condition. We searched the literature for patients presenting with intraosseous sarcoidosis of the jaw through June 2020 using key phrases. Additional papers were included via a search of references and citing papers.

An Anatomic Predisposition to Mandibular Angle Fractures.

Purpose: To investigate a predisposition to mandibular angle fractures, a retrospective study was performed in which fractured mandibles were compared with healthy mandibles with no history of fracture. Other investigations of angle fracture risk have exclusively studied patients with existing fractures. In addition, the risk has not been comprehensively explained in conjunction with the specific features of mandibular anatomy.

A Rare Case of Odontogenic Chronic Suppurative Otitis Media.

Common causes of chronic suppurative otitis media (CSOM) include persistence of acute otitis media, cholesteatoma, and eustachian tube dysfunction. We describe a patient who presented with CSOM of several years duration refractory to medical management. Ultimately, a dental abscess was found on computed tomography (CT) to be the source of concurrent ipsilateral maxillary sinusitis and mastoiditis.

Utilization of tracheostomy in craniomaxillofacial trauma at a level-1 trauma center.

Purpose: The decision to perform a tracheostomy on patients with maxillofacial trauma is complex. There is little data exploring the role of tracheostomy in facial fracture management. We sought to profile the utilization of tracheostomy in the context of maxillofacial trauma at our institution by comparing patients who required tracheostomy with and without facial fractures versus those with facial fractures not requiring tracheostomy.

Facial soft tissue injuries as an aid to ordering a combination head and facial computed tomography in trauma patients.

Purpose: While the trauma computed tomography (CT) head scan is frequently ordered during resuscitation of multiply injured patients, determining when also to order facial CT in these situations can be difficult. Consequently, facial fractures are commonly missed on initial imaging evaluation. In acute trauma situations, facial soft tissue injury markers are often used to aid in this decision.

Facial computed tomography use in trauma patients who require a head computed tomogram.

Purpose: Head-injured patients admitted to a trauma center may or may not have associated facial fractures. Most head-injured patients undergo head computed tomography (CT) scan early in their evaluation. The question of adding a facial CT at the time of the head CT can be unclear.

Referral patterns for the treatment of facial trauma in teaching hospitals in the United States.

Purpose: The management of facial trauma is considered an integral part of the training of several specialties, including general plastic surgery, otolaryngology, and oral and maxillofacial surgery. Referral patterns of patients who have sustained facial trauma to these various specialty services, however, vary at different institutions according to physician preferences and protocols. The purpose of this project was to examine the referral patterns of facial trauma in the United States at teaching hospitals.
