Cyst On Midline Floor Of Mouth

Floor of mouth dermoid cysts account for 1 6 of all dermoid cysts 2 and they usually present as a midline symmetrical slowly enlarging lesion.

Cyst on midline floor of mouth.

We present the first reported case of a multifocal floor of mouth fom cervical tgdc representing an atypical embryonic course. Sixteen cases of patients with a diagnosis of midline cyst of the floor of the mouth treated at the maxillofacial surgery department of the school of medicine and surgery of the federico ii university of naples naples italy were observed over a 10 year period between 1988 and 1998. At imaging they appear as midline simple cystic lesions and are often indistinguishable from ranulas fig 12. Most tgdcs occur in the region of the hyoid bone but have been found less commonly in areas from the oral cavity to the sternum.

Age sex localization diagnostic technique and type of treatment were evaluated. Cysts superficial to geniohyoid may cause posterosuperior displacement of the tongue dysphonia dysphagia 3 or airway obstruction 4. Sixteen cases of patients with a diagnosis of midline cyst of the floor of the mouth treated at the maxillofacial surgery department of the school of medicine and surgery of the federico ii university of naples naples italy were observed over a 10 year period between 1988 and 1998. Epidermoid cysts are lined by simple squamous epithelium and are more frequently seen in the floor of mouth than in the submandibular space.

An incision is made on the floor of the mouth horizontally above the sublingual caruncle. Age sex localization diagnostic technique and type of treatment were evaluated. During the surgery to remove this cyst doctors found another deeply embedded in the mylohyoid muscle at the floor of the mouth which required careful separation. A thyroglossal duct cyst tgdc is a common pediatric midline neck mass.

Figure 3 by blunt dissection the lesion is completely dissected figure 4 until its complete excision in a single piece figure 5. The piece is sent to histopathological study where it is diagnosed as thyroglossal duct cyst. Ranulae present as a swelling of connective tissue consisting of collected mucin from a ruptured salivary gland caused by local trauma.
