Calculus formation in salivary glands (sialolithiasis) is one of the most common diseases of the salivary glands and is most commonly seen in the submandibular gland. Not only can the stones be small and inside the duct, they may also get larger and reside inside the gland. We can easily see submandibular sialolithiasis perforating the floor of the mouth in cases having sialolithiasis for decades and not having any treatment and its transoral removal as we look in the medical literature. A 52-yearold lady who had rejected surgical treatment for submandibular sialolithiasis for 25 years is presented as a case in this study. Treatment of the case was performed effectively by taking out the calculus transorally with a simple intervention whose examination revealed that the calculus was seen to perforate the floor of the mouth. It is aimed to stress with this case that transoral removal of submandibular sialolithiasis that perforates the floor of the mouth without performing external approaches is a method that has to be thought in the first step.
