Abstract
Materials and Methods.Thirty-eight participants who had undergone a partial maxillectomy and who were wearing dentomaxillary prostheses were enrolled between September 2014 and April 2016. The participants were allocated to 2 groups according to the type of defect after healing: 19 consecutive participants had a closed defect and 19 consecutive participants had an open defect. Masticatory function was evaluated objectively and subjectively. OHRQoL was assessed using the GOHAI questionnaire. Differences in the scores obtained by the 3 measures were compared between the 2 groups using the Wilcoxon rank-sum test (α=.05).Results.No significant differences were seen between the 2 groups in objective mixing ability, subjective masticatory score, or GOHAI (P>.05). Regarding the GOHAI physical function domain, only the swallowing item was significantly lower (P=.025) in participants with an open defect than in participants with a closed defect. Regarding the GOHAI psychological function domain, the item on patients’ psychological worries or concerns about their teeth, gingival tissue, or dentures was significantly lower (P=.045) in patients with an open defect than in those with a closed defect. Conclusions.The type of defect, closed or open, in patients who had undergone a partial maxillectomy might not influence their masticatory function and overall OHRQoL if they have adequate prosthetic rehabilitation.
