Spring Obturators: A Functional Solution for Palatal Defects

Abstract

Introduction: During the severe second wave of the COVID-19 pandemic, India faced a notable increase in cases of COVID-19-associated mucormycosis, a serious fungal infection caused by Mucorales species. This infection is highly angioinvasive and spreads rapidly. Many patients underwent bilateral subtotal maxillectomy due to the aggressive nature of the fungus. Reconstructing the resulting defect is challenging, and there is limited data on creating delayed surgical obturators for these cases. Aim: This design aims to produce an appliance that is easy to fabricate, adjust, cost-effective, and comfortable for patients. Materials and Methods: The surgical obturator will use a spring made of 22 gauge stainless steel wire. The thick gauge addresses postsurgical trismus and creates a seal between the acrylic plate and the dorsum of the tongue during swallowing, aiding in the patient's ability to take a soft diet initially. Conclusion: The spring obturator represents a novel, patientcentric solution for addressing the functional and structural challenges associated with bilateral subtotal maxillectomy due to mucormycosis. Its simplicity and affordability make it a promising option for widespread clinical application.
