This case series describes the prosthodontic treatment of five patients who were treated with surgical resection, with or without flap reconstruction, and had remaining oronasal fistulas following their maxillary neoplasms. All five patients obtained spontaneous closure of their partial maxillectomy defects following the use of a maxillary protective removable dental prosthesis that did not engage the fistula.
Nguyen et al. (2026) studied this question.
