Removal of Large Palatal Torus: Case Report 3 of 4
3. Discussion
The palatal torus is characterized by a benign bony protuberance located in the mid-
line of the palate, with a higher prevalence in females [1]. The etiology of torus develop-
ment is still unknown. However, recent studies have reported that its prevalence may be
closely related to heredity and environmental factors, including dietary habits, the use of
medications such as phenytoin, and the patient's nutritional status [3]. Torus exhibits
slow but progressive growth, with the highest growth rate between the second and third
decades of the patient's life [4,5]. The classification of the size of the palatal torus is based
on the shape and height from the base to the peak, with the following measurements:
small (0 to < 3 mm), medium (3 to < 5 mm), and large (≥ 5 mm) [1].
Generally, tori are asymptomatic, and the indication for surgical removal is closely
related to prosthetic rehabilitative treatment, as a donor source for bone grafts in implant
surgery, or at the patient's request. However, there are other reasons for surgical indica-
tion, such as chewing limitations, traumatic ulcers, food retention, high sensitivity, and
speech disorders [3]. When there is difficulty with the stability of a denture, the only
treatment is surgical excision, as well as in cases of ulcerations, dysphagia, and local
trauma, with surgery under local anesthesia [6] and flap repositioning that can be made
in four types: "Y" or double "Y" incision, semilunar incision with a lateral base, full-thick-
ness incision, and modified incision [6].
In the clinical case presented, a "Y" incision was chosen because the structure of the
lesion extended to the limits of the soft palate, although its base was on the hard palate.
"Y" incisions are the most commonly used due to the broad exposure they offer and the
minimization of risks of injury to the nasopalatine and greater palatine nerves [7]. After
flap creation, the mucoperiosteal detachment must be performed with great caution to
avoid tissue laceration. It is also important to be cautious during the osteotomy to prevent
the creation of an oroantral communication [7].
4. Conclusion
The clinical case illustrates the removal of a palatal torus in a patient indicated for
prosthetic rehabilitation with a complete denture. The surgical removal of the torus was
the first-choice treatment, with an individualized selection of the surgical access, requir-
ing caution during the osteotomy stage of the exostosis.
