Comprehensive perioperative and minimally invasive post-operative defect approach of massive palatal pleomorphic adenoma: Case series

Abstract

Introduction and importanceExtensive Palatal post-operative defect management following excision of neoplasm is one of the most difficult challenges for oral and maxillofacial surgeons regarding its limited surgical access and visibility on narrow area, airway management difficulty during intubation, richness of maxillary vascular network resulting in enormous bleeding risk. Decision making regarding its surgical approach and impact on speech and mastication is important. This case series aim to describe comprehensive step by step perioperative and palatal defect management approach based on tumor pathological characteristic and anatomical perspective to achieve good surgical outcome. Cases presentationTwo cases of massive palatal pleomorphic adenoma were presented. Both of cases occurs in female patients. Lesions was crossing the midline, impair speech and causing discomfort. Preoperative diagnostic from CT scan and FNAB result was pleomorphic adenoma. Clinical discussionSurgery for both cases done with wide periosteal sacrificing excision, ostectomy and surgical obturator placement from intraoral approach under general anesthesia with nasal intubation. Eventually the wounds healed without wound dehiscence and fistula, no speech impairment and no sign of reccurency. ConclusionUnderstanding pathological characteristic of pleomorphic adenoma and basic anatomy of surrounding structure are important to formulate minimal invasive surgical and post-operative defect management planning and improve patient's quality of life.
