Subantroscopic laterobasal sinus floor augmentation (SALSA): an up-to-5-year clinical study.
OBJECTIVE
The aim of the article was to introduce a new subantroscopic laterobasal sinus augmentation (SALSA) tecnique as a minimally invasive approach to maxillary peri-implant surgery.


METHODS
The SALSA technique consists of the following steps: (1) microsurgical opening of the subantral space (SAS) with detachment of the sinus membrane (SM) under supported videoendoscopy; (2) enlargement of the SAS by laterobasal tunnelling; (3) subantroscopic examination of the SAS with (4) optional reinforcement or repair of the SM; (5) implant site preparation with subantroscopic identification of the cavities; and (6) precise stepwise placement of graft material under endoscopic control.


RESULTS
Since 1996, 118 sinus augmentations have been performed on 83 patients using particulate alloplastic augmentation material (tricalcium phosphate) with various amounts of autogenous bone and blood. Mean augmentation height was 8.6 mm (range, 1 to 15 mm). Twenty-eight perforations of sinus mucosa were observed without further complication (1 case of sinusitis was treated and re-augmented endoscopically). Of 211 titanium screw-type implants placed, 11 failures were observed.


CONCLUSIONS
SALSA is a predictable surgical technique. With this minimally invasive method, adequate bone height can be achieved.


CONCLUSIONS
SALSA may offer advantages related to lower morbidity, conservation of bone volume and blood supply, optimized view of the surgical field, and high acceptance by patients.
