Abstract: Maxillary defects lead to deficits in mastication，swallowing，speech and facial symmetry，thereby resulting in the low quality of life. Obturator prostheses or vascularized free composite flaps can reconstruct the maxillary defects，which can partially restore the patients′ oral functions and facial esthetics. Evaluation of the outcomes of maxillary reconstructive surgery and/or obturator is an important basis for improving treatment strategies. The maxillary reconstructive outcomes are evaluated based on oral functions，facial esthetics and patients′ satisfaction，which will provide a reference for further clinical researches. 

Key words: maxillary defects, free flaps, obturator, oral function, quality of life
