Exostoses present benign bony overgrowths of the maxilla or mandible. The most common region of exostoses is located on the midline of the palate, known as palate tori. Exostoses can occur as single or multiple phenomenons which grow slowly and continuously over years with nearly no size limiation. Their existence, however, often remains unnoticed due to the condition staying mostly asymptomatic unless the overlaying mucosa becomes traumatised.
The condition is associated with temporomandibular dysfunction, tooth attrition, several medications and medical conditions.
Indications for a surgical removal are not only given mostly if the situation interferes with a planned removable appliance, but sometimes also if the size of the tori interferes with the oral function or if there are concerns of malignancy.
