“…When accesses to the antral cavity from the lateral wall are contraindicated, entry to the sinus cavity transcrestally or palatally are the viable alternatives. An indication for palatal approach is illustrated in Figure 14 where the existing sinus graft is inadequate and more graft is needed via a re-entry procedure (Figure 6) [3,41].…”

“…Schneiderian membrane perforation is the most common intra-operative complication associated with sinus augmentation procedures [42]. Frequency rates ranging from 11% up to 56% have been reported [41,43]. Membrane perforation has been related to a higher post-operative infection incidence as it threatens the coverage and containment of the bone graft [44,45].…”

Rehabilitation of patients with endosseous implants in the posterior maxilla poses a challenge as a result of sinus pneumatization and ridge atrophy. Sinus augmentation has been established to be a reliable procedure to facilitate implant therapy. However, despite the predictability of the techniques and biomaterials employed in sinus graft procedures, intra-operative complications still occur leading to increased surgical time, abortion of the surgery, post-operative infections and loss of implant. Based on the clinical findings and literature review, a hierarchical decision tree to minimize intra-operative complication is proposed. Several host-related factors, which can influence the outcome of the procedure, are identified. The factors are health status of the sinus, size and location of the endosseous anastomosis, lateral wall thickness, membrane thickness, remaining residual bone height, and presence of sinus floor cortication.

“…As seen in this case, incomplete bone formation can be managed with re-entry procedures, but incomplete bone formation often results in unusual sinus floor morphologies that make conventional sinus approaches difficult. A recent case report describes an unconventional palatal approach for managing sinus floor anatomy complicated by previous sinus grafting [15]. …”

BackgroundPatients with resorbed edentulous alveolar ridges in the posterior maxilla often require lateral window sinus augmentation procedures prior to implant placement. Lateral window sinus augmentation procedures can produce incomplete bone augmentation as consequence of surgical and healing complications producing unusual and complex sinus anatomy. Although incomplete bone formation after sinus augmentation has been described in a previous case reports, this is the first case report that describes grafting these compromised sites prior to implant placement.Case presentationA 65-year-old male patient with no known medical conditions presented with severe chronic localized periodontitis and a combined periodontal-endodontic lesion affecting three first molars. Initial ridge preservation and lateral window sinus augmentation resulted in incomplete bone formation and complex sinus floor anatomy on both right and left sides. A dilating balloon technique on one side and a palatal approach on the other side were utilized for additional sinus augmentation using particulate allograft and resorbable collagen membranes. Healing was uneventful, and implants could be placed and restored at all sites. Periodontal maintenance was conducted every 3 months, and the implants have been in function and periodontally healthy for 2 years.ConclusionDespite initial failure of sinus augmentation to produce suitable implant sites, it is possible to rescue these sites with re-entry grafting procedures and allow successful implant placement and restoration.

Maxillary sinus augmentation through a lateral window is reported as one of the most predictable bone augmentation procedures before implant placement. The elevation of the membrane represents a delicate and crucial step that allows the creation of the space for the bone graft material. If the elevation is not completed, the regenerated bone might be inadequate for the implant placement. In this case, a new intervention will be necessary to complete the bone augmentation. Reaccessing from a lateral window, however, would be challenging due to thickness of the buccal boney wall because of the first grafting procedure; therefore, a different approach has to be used. The aim of this case report is to present the palatal window technique for treating incompletely augmented maxillary sinus. The detailed step-by-step diagnostic and surgical procedures are described, and the advantages and limitations of the technique are discussed through a review of the literature.
