Conservation of the quality of life after tumor surgery requires a total treatment plan for reconstruction such as postoperative occlusion, chewing and pronunciation function, as well as treatment of the original disease before surgery. A smooth transition from surgery to maxillofacial prosthodontic treatment will enable an early return to life after surgery. In cases of maxillary defects in which an oral nasal cavity fistula is expected after surgery, the appropriate application of an immediate surgical obturator (ISO), is an important factor in maintaining postoperative quality of life and early social reintegration.
