Case report: Sustaining an obturator prosthesis with zygomatic suspension wires in a case of subtotal maxillectomy and insufficient ridge supported retention: A case report Matheel AlRawas1, Farah Rashid2, Aparna Barman3, Taseef Hasan Farook4, Ayman ALOulabi5, Nafij Bin Jamayet6, Mohammad Khursheed Alam7 Abstract: Purpose: For making denture in maxillectomy cases is very difficult and challenging to get the retention to make the denture stable in its position during functioning. This case report describes a clinical condition in which patient was treated with a maxillary obturator with zygomatic suspension wiring due to insufficient retention in the palate. Materials and Methods: A 63-year-old patient had gone to a subtotal maxillectomy because following myofibroblastic sarcoma andwas issued with bilateral circum-zygomatic wiring hooks immediately after surgery. The patient had less than a third of their alveolar ridge remaining and did not provide sufficient retention on its own. The wires were used for the retention because natural retention could not get due to inadequate maxillary ridge. While the denture was being fabricated, a temporary feeding plate was provisioned to the patient. Counter hooks were implemented on the definitive upper denture, posterior to molars, to attach to the zygomatic suspension hook. Final upper denture was further reinforced with denture adhesive on it. A lower denture was also fabricated for the said case following conventional protocols of jaw relation determination. Results: The obturator provided with adequate seal and leak proof phonetics. The zygomatic wiring coupled with denture adhesive were sufficient to provide adequate retention. Conclusion: Zygomatic suspension wires coupled with counter hooked obturator prosthesis provide rehabilitation of patients with palatal defects with inadequate maxillary arch for retention.However long-term repeated use of such wires might expose the patient to secondary infections and should be kept in consideration Clinical Significance: Circum-zygomatic suspension wiring provide sufficient retention to sustain the upper obturator prosthesis in place. However, the retention was still inadequate, so denture adhesives were used to make it more stable.
