Three-dimensional evaluation of a giant torus in the maxilla and mandible that affected pronunciation: a case report

Introduction and importance: Tori in the maxilla and mandible are often clinically asymptomatic, but can often lead to issues such as obstruction of denture attachment and dysarthria. The authors describe a case involving a substantial torus in the maxilla and mandible that significantly affected speech articulation. Case presentation: A 72-year-old woman presented with a pronounced torus in the maxilla and mandible. Surgical resection of the lesion resulted in improved tongue movement. Through both pre and postoperative assessments, the authors evaluated pronunciation, generated a three-dimensional (3D) computed tomography (CT)–based image, and quantified the extent of bone removal. A 6-month follow-up demonstrated no recurrence of the condition. Clinical discussion: Surgical intervention leads to improvements in soft palate sounds. The surgical intervention proved effective in ameliorating speech articulation difficulties, and the application of 3D-CT image construction was valuable. Conclusion: To summarize, the authors successfully managed and treated a giant torus in the maxilla and mandible, a condition scarcely been reported in the literature. This report is the first to detail the application of 3D analysis for the evaluation a torus.
