Management of Mucormycosis Resultant Hemimaxillectomy Defect from Interim Hollow Obturator to Definitive Two-Piece Magnet Retained Prosthesis - A Case Report

Abstract

In case of large surgical defects, single-piece hollow bulb obturator prosthesis may increase the height and weight of the prosthesis resulting in loss of retention and difficulty while insertion and removal of the prosthesis. In the present case, patient presented with a large hemimaxillectomy defect with restricted mouth opening. A novel strategy for rehabilitating the patient with a major palatal deformity and restricted mouth opening by fabricating two-piece prosthesis is described in this case report.

Post maxillectomy definitive rehabilitation in post-covid mucormycosis patients using conventional and 3D printed obturator: A twin case report

“…Mucormycosis is an invasive fungal infection commonly reported during second wave of Covid-19 especially in patients who underwent oxygen therapy and corticosteroid medication [1,2]. The rhinocerebral form of mucormycosis is the most common form affecting the oral, nasal, orbital and paranasal sinus regions.…”

“…Surgical resection in these patients results in complete or partial maxillectomy due to which the patient has drastic dimensional changes in the extraoral and intraoral region including collapsed facial form and profile, inadequate soft tissue support, reduced lower facial height, oro-antral communication, and unesthetic senile appearance. It also affects mastication, speech, swallowing, facial expression and mandibular movements [1,3].…”
