Abstract

Backgrounds: Thermoplastic masks are used for patient immobilization in radiotherapy. Water bath and dry heat oven are used for thermoplastic masks warming before molding on the patient’s skin.

Objective: To compare the effectiveness and satisfaction between water bath and dry heat oven for thermoplastic mask molding in radiotherapy.

Materials and methods: The effectiveness of the water bath and the oven was examined in 3 categories: 1) preheat time, 2) mask warming time, and 3) mask molding time. The data of 20 patient who used thermoplastic masks were collected from August to September 2020. The thermoplastic masks were separated to new short mask, new long mask, reused short mask, and reused long mask. In addition, the satisfaction survey of usage a water bath and an oven for thermoplastic mask molding was evaluated by questionnaire from the radiotherapists.

Results: The results of effectiveness of the water bath and the oven were: 1) The average preheat time to 67 °C of the water bath was longer than the oven, 2,772.0±20.8 seconds and 103.3±5.8 seconds, respectively.  2) The mask warming time of the water bath was significantly shorter than the oven. 3) The mask molding time was not significantly different between using the water bath and the oven. The satisfaction survey from the radiotherapists which relevance with the water bath in very good levels was mask molding time, restore time for reusable, and reshape in a specific area. Meanwhile, the oven was very impressed in the mask’s cleanliness and the clean-up method.

Conclusion: The overall effectiveness of thermoplastic mask molding for radiotherapy by using the water bath and the oven was not different. The satisfaction scoring parameters of the water bath was maximum in reshape in a specific area, but the oven is cleanliness.
