Evaluation of maxillary sinus after treatment of midfacial fractures

Comparison of Hand and Semiautomatic Tracing Methods for Creating Maxillofacial Artificial Organs using Sequences of Computed Tomography (CT) and Cone Beam Computed Tomography (CBCT) Images

“…Regarding the treatment of paranasal sinus pathologies (e.g., squamous cell carcinoma resection, reposition after traumatic injury), it is essential to realize and visualize the proper conditions of the pathological disorder and the surrounding anatomic structures. The maxillary sinus is the most frequently affected anatomic landmark in midfacial fractures (44). Furthermore, Cantini Ardila et al (45) concluded that there is a correlation between facial fractures and the sphenoid sinus and also sphenoid bone fractures.…”

A Hemangioma of the Zygomatic Bone: Management Ensuring Good Reconstructive and Aesthetic Results

“…If bone healing is poor, and bone loss develops even after placement of a titanium grid, sinus function can be disturbed, imparting a predisposition toward sinusitis. 24 Many authors recommend either embolization or external carotid ligation, 4,18,25,26 while others find that proximal vascular control is unnecessary if the margin of normal bone is adequate after resection. 4,25,27 Radiotherapy stops progression of the lesion, but does not address the cosmetic deformity and may cause tissue necrosis, slowing down bone and tooth growth, and causing telangiectasis and malignant degeneration 18 (►Fig.…”

Marked gastric uptake of Tc-99m methylene diphosphonate (MDP) in a patient with myeloma and hypercalcemia

“…After nasendoscopy, the patient's nasal mucosa was found to be entirely normal. Increased uptake of MDP in the paranasal sinuses may be posttraumatic or related to inflammatory or infective pathology ( 11 , 12 ). In our patient, there was no history of trauma or any other clinical evidence of inflammatory change in the nasal cavity or nasopharynx.…”
