Maxillary sinus augmentation with iliac autograft - a health-economic analysis

To estimate and compare the costs of maxillary sinus augmentation performed with autologous bone graft either from the iliac crest or from local bone harvested from the mandibula. To evaluate post-operative health-related quality-of-life parameters for patients subjected to sinus augmentation and iliac bone surgery.

The hospital records of 14 patients subjected to sinus augmentation with iliac autograft, and 14 patients treated with local autograft, were analysed with regard to costs related to surgery, hospitalization and sick leave. Post-operative health parameters were assessed with a questionnaire.

Mean hospital costs, administration excluded, for sinus augmentation with iliac autograft was €3447. Policlinic treatment alternatives e.g. local bone autograft with or without bone substitutes, rendered costs of approximately 42% thereof. The loss of production for a worker was 41% of the total cost (€9285). With regard to health-related quality-of-life and post-operative morbidity, most of the patients had recovered 14 days after the iliac graft surgery.

The cost for a sinus augmentation with iliac surgery exceeds that of a policlinic procedure manifold. Provided that a policlinic operation with local bone, with or without bone substitute, renders an adequate end result, the economic gain would be substantial and post-operative morbidity would be greatly reduced.
