A definitive maxillary obturator prosthesis can be used to rehabilitate a maxillary defect with the aim of improving speech, deglutition, and elimination of oronasal regurgitation. The aims of this study were (1) to determine the time required to fabricate a definitive maxillary obturator prosthesis and (2) to compare the fabrication and follow-up times between a patient's first and second definitive maxillary obturator prosthesis.
A retrospective review was completed of patients that had maxillary definitive obturators fabricated following head and neck surgery from 2002 to 2018 (n = 173). Demographics, clinical data, date of surgery, start date of fabrication, follow-up dates, and prosthesis follow-up data were collected.
The median time to delivery of the patient's first definitive maxillary obturator prosthesis from the date of surgery was 7.7 months for nonradiated patients and 9.6 months for radiated patients (P ≤ .05). Additionally, there was a significant difference in the median number of appointments to fabricate the 1st definitive maxillary obturator prosthesis as compared to the 2nd prosthesis (6 vs 5; P ≤ .05).
Fabrication timelines differed based on history of radiotherapy and patient experience. This data is helpful to set expectations for patients and practitioners regarding the process for prosthesis fabrication and follow-up.
定制的上颌阻塞器假体可用于修复上颌骨缺损,旨在改善言语、吞咽功能并消除口鼻反流。本研究的目的是:(1)确定制作定制上颌阻塞器假体所需的时间;(2)比较患者第一副和第二副定制上颌阻塞器假体的制作时间和随访时间。
对2002年至2018年接受头颈部手术后制作上颌定制阻塞器的患者进行回顾性研究(n = 173)。收集人口统计学资料、临床数据、手术日期、制作开始日期、随访日期和假体随访数据。
非放疗患者从手术日期到第一副定制上颌阻塞器假体交付的中位时间为7.7个月,放疗患者为9.6个月(P≤0.05)。此外,制作第一副定制上颌阻塞器假体与第二副假体的预约中位数存在显著差异(6次对5次;P≤0.05)。
制作时间线因放疗史和患者经历而异。该数据有助于患者和从业者对假体制作及随访过程建立预期。
