Enophthalmos developed in a 44-year-old woman with history of respiratory infection but not of sinus disease. Sinus roentgenograms and MR revealed opacification of the right maxillary antrum, deviation of the nasal septum to the right, obstruction of the right osteomeatal complex, and diminished volume of the right maxillary sinus.

OBJECTIVE The availability of a low dose radiation technology such as Cone Beam Computed Tomography (CBCT) in dental practice has increased the number of scans available for forensic purposes. Moreover, specific software allows for three-dimensional (3D) characterization of the maxillary sinuses. This study was performed to determine whether sinus maxillary volumes can be useful to identify gen...

OBJECTIVES The purpose of the present study was to explore the maxillary sinus anatomy, its variations and volume in patients with a need for maxillary implant placement. MATERIAL AND METHODS Maxillary sinus data of 101 consecutive patients who underwent spiral computed tomography (CT) scans for preoperative implant planning in the maxilla at the Department of Periodontology, University Hospi...

BACKGROUND We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the p...

Introduction: Maxillary sinus lift combined with implant placement without grafting allows bone formation in the sinus. However, bone volume in severely atrophic maxilla is often insufficient to ensure initial stability of implants. The purpose of this study was to evaluate the outcome of maxillary sinus augmentation by graft-free two-stage sinus lift using titanium bone fixation device and imp...

introduction a mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. mucopyocele is an infected mucocele. case report we presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. computed tomography scan showed opacification of the left maxillary sinus expanding thr...

BACKGROUND: Insufficient bone volume is a common problem encountered in the rehabilitation of the edentulous posterior maxillae with implant-supported prostheses. Bone volume is limited by the presence of the maxillary sinus together with loss of alveolar bone height. Sinus lift procedures increase bone volume by augmenting the sinus cavity with autogenous bone and/or commercially available bio...

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

Endosseous implants are frequently used for prosthetic reconstruction in the edentulous patient. Sufficient volume and density of the alveolar bone for implant integration and load bearing are prerequisites for good clinical outcome. Bone resorption following the extraction of posterior maxillary teeth sometimes results in severe loss of bone in vertical and ⁄ or horizontal dimensions, which ma...

ameloblastomas are slow growing, locally invasive, benign odontogenic tumors of an epithelial origin, accounting for approximately 1% of all oral tumors. a 40-year-old man presented with a chief complaint of a swelling over the left side of his face of 4 years’ duration. on examination, gross facial asymmetry was detected, and a well-defined swelling was noted intraorally involving the left max...
