BACKGROUND: Malar augmentation is a common cosmetic procedure utilizing silastic materials. We describe an uncommon complication of a silastic implant eroding into the anterior maxillary sinus wall resulting in chronic rhinosinusitis (CRS). METHODS: A literature review is presented describing the presentation, surgical management and outcome of this uncommon adverse event. RESULTS: An 80 year old female with a history of bilateral cosmetic malar implants placed approximately 25 years ago presented to our office with a 4-5 month history of left-sided symptoms consistent with chronic sinusitis, and was found to have intrasinus penetration of her left malar implant...

Background. One of the most problematic regions for endosseous implants is the posterior maxilla, not only having poor bone density, but also lacking adequate vertical height as a result of sinus pneumatization. The purpose of the present study was a radiologic, histological, and histomorphometrical evaluation, in humans, of specimens retrieved from sinuses augmented with decellularized bovine compact particles, after a healing period of 6 months. Methods. Four patients, with atrophic resorbed maxillas, underwent a sinus lift augmentation with decellularized bovine compact bone from bovine femur...

Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique that also exploits the guided surgery approach for design and preparation of a lateral window for sinus augmentation, the Low Window Sinus Lift...

PURPOSE: This human case series presents the clinical and histologic results of five cases of peri-implantitis with subsequent sinus graft infections. Complications may follow maxillary sinus augmentation procedures. It is possible to have an inflammatory reaction, movement of the implant inside the sinus, formation of an insufficient quantity of osseous tissue, and the production of an oroantral fistula. Complications following maxillary subantral augmentation procedures are relatively rare; however, the risks and benefits of any surgery must be carefully evaluated at the onset...
