Abstract
The rehabilitation of a maxillectomy patient involves meticulous treatment planning and designing. Lack of retention and facial support and limited mouth opening are the major issues that lead to functional and psychological trauma in post-maxillectomy patients. The successful rehabilitation of a maxillary defect includes restoring the function, esthetics, and a complete obturation of the defect, enabling the patient to feed without nasal regurgitation. This case report describes the fabrication of an obturator with a modified design, namely a split-antral hollow bulb obturator and oral part that is retained with a ball attachment, for a patient with right-side acquired maxillary defect due to recurrent myxoma. The primary advantage of this modification is enhanced facial support and a self-retentive antral obturation that improved the quality of life of the patient after an extensive maxillectomy.
Highlights
Acquired maxillary defects are primarily due to neoplasm of the nasal and paranasal sinuses and osteomyelitis due to a bacterial or fungal infection
Prosthesis delivery to a maxillectomy patient improves the quality of life by eliminating nasal leakage, unintelligible speech, swallowing difficulties, impaired mastication, unesthetic appearance, and psychological suffering [5]
The success of the obturator prosthesis is affected by the maxillectomy procedure, which influences the remaining supporting structures of the oral cavity, the extent of the reconstructed defect, and its severity
Summary
Acquired maxillary defects are primarily due to neoplasm of the nasal and paranasal sinuses and osteomyelitis due to a bacterial or fungal infection. Due to the extensive nature of this intraoral defect (as shown in Figure 2), the obturator was fabricated in two parts, consisting of a hollow antral part and an oral part. It functions only when pushed by the second inferior part to engage the defect and support the eyeball This inferior one-third of the antral bulb is an extension of the oral part. The framework with the wax pattern was acrylized (heat-cure acrylic, DPI, Mumbai, India) The oral part contains the inferior hollow bulb, artificial teeth and the female part of the attachment
