Tumors rarely arise in the sublingual salivary glands. They should be considered malignant until proved otherwise. Adenoid cystic carcinoma is most commonly encountered malignant tumor of the sublingual gland. We report a case of adenoid cystic carcinoma arising from the sublingual gland. Moreover, the sublingual gland had anatomic variation of main duct(Bartholin's duct) which is connected to Wharton's duct.

Sialolithiasis is relatively common disease of the salivary gland in the field of Oral & Maxillofacial surgery. Obstruction of salivary secretion by a sialolith can result in swelling and pain, as well as infection of the gland. The swelling is usually correlated to meals, when salivary secretion is enhanced. Sialolithiasis occurs mainly in the submandibular gland(92%) and to a lesser degree in the parotid gland(6%). The sublingual gland and the minor salivary gland are rarely affected(2%). This is a report of rare case, the authors have experienced, within the left sublingual gland and the minor salivary glands. It is multiple sialolithiasis(about 22 silaoliths) in the sublingual and the minor salivary glands which has very low incidence of sialolithiasis. The pathosis were removed using transoral sialolithotomy with sublingual sialadenectomy.

Ranula is a mucocele caused by extravasation of the sublingual gland on the floor of the mouth. The most common presentation is a cystic mass in the floor of the mouth. A portion of the sublingual gland could herniate through the mylohyoid muscle, and its extravasated mucin can spread along this hiatus into submandibular and submental spaces and cause cervical swelling. This phenomenon is called plunging ranula. A variety of treatments for ranula has been suggested and include aspiration of cystic fluid, sclerotherapy, marsupialization, incision and drainage, ranula excision only, and excision of the sublingual gland with or without ranula. Those various treatments have shown diverse results. Most surgeons agree that removal of the sublingual gland is necessary in oral and plunging ranula. Four patients with ranula were investigated retrospectively, and treatment methods based on literature review were attempted.

The mucocele is a mucus extravasation cyst arising from the salivary gland. Although it is a common?lesion of the minor salivary gland, it is uncommon when it originated from the submandibular gland. The ranula is a form of mucocele which specifically occurs in the floor of the mouth and the sublingual gland is generally accepted as the origin of ranula. They can be classified into two types based on extent: simple ranula are confined to the sublingual space and plunging ranula extend into the adjacent space. It is difficult to differentiate the submandibular gland mucocele from the plunging ranula because both of them can occupy the submandibular space. A 37-year old male visited our clinic with the chief complaint of left facial swelling. The patient's history revealed that he had suffered from a cystic lesion on the left side of the floor of the mouth 10 months previously. He supposed the cystic lesion had come from trauma at other dental clinics. Using CT and MRI, we diagnosed a simple ranula on the sublingual space and a submandibular gland mucocele. We then excised the mucocele with the submandibular gland by an extraoral approach and the sublingual gland by an intraoral approach under general anesthesia. We report a rare case of an enormous submandibular gland mucocele which extended into the pterygoid plate and parapharyngeal space with good surgical results.

It was performed to evaulate the effects of occlusion of mandibular gland and sublingual gland on the mandibular gland in dogs. The occlusion of mandibular gland and sublingual gland was induced by ligature in clinically normal dogs, and ultrasonograpic appearance, hematological changes and histological changes of the mandibular gland were observed daily during 6 days. The results were as follows. 1. The length, width, circumference and area of the mandibular gland in clinically normal dogs were 25.1 mm, 8.4 mm, 56.4 mm and 163.0 $\textrm{mm}^2$ in the left, and 23.4 mm, 8.0 mm, 53.3 mm and 141.6 $\textrm{mm}^2$in the right. 2. The length, width, circumference and area of the mandibular gland were gradually increased after ligature of the salivary duct, and revealed maximum values, as 33.4 mm, 10.9 mm, 73.0 mm and 287.2 $\textrm{mm}^2$, respectively, at 24 hours after ligature, and returned to normal size at 3 days after ligature. 3. The size of the opposite mandibular gland without ligature was also gradually increased until 24 hours, and returned to normal size at 3 days, similar to the changes of the mandibular gland with ligature. 4. There were no significant changes after ligature of the salivary duct in hematological findings. 5. In histopathological findings, the major of glandular alveoli was enlarged at 24 hours after ligature of the salivary duct, and neutrophils and monocytes were infiltrated at 6 days after ligature.

Ductal papillomas are rare benign lesions of the salivary glands with two distinctive types, intraductal and inverted. The rarest anatomical location where intraductal papillomas occur is the major salivary glands. In the present study, we report an intraductal papilloma of the left sublingual gland with the relevant clinical, imaging, and histopathological findings and postoperative follow-up. To our knowledge, this is the fourth case of an intraductal papilloma of a sublingual gland to be reported in the international literature. We present this rare case because of its clinical and radiological imitation of a ranula.

Objectives: This study evaluated the clinical results of partial sublingual glandectomy accompanying the excision of ranula as new treatment modality. Materials and Methods: A total of 43 patients who were treated between 1999 and 2007 for oral or plunging ranula were reviewed. All patients were treated surgically by various methods with a total of 55 different procedures performed. Ten cases of partial sublingual glandectomy with excision of the ranula were conducted. All excised specimens were examined. We compared the clinical outcomes resulting from each treatment method. Results: The recurrence rates for marsupialization, excision of ranula, marsupialization with gauze packing, total excision of sublingual gland and ranula, and partial sublingual glandectomy with excision of ranula were 50%, 25%, 25%, 0% and 10%, respectively. Of the 10 patients treated by partial sublingual glandectomy with ranula excision, only one experienced recurrence (10%), i.e., plunging ranula. None of the ranulas contained an epithelial lining, and the excised portion of the feeding sublingual glands showed degenerative changes. Conclusion: In removal of ranulas, we found that excision of the attached sublingual gland, which removed the feeding portion and degenerative acinar cells, yielded good outcomes. Thus, as a new conservative method for treatment, we recommend partial sublingual glandectomy to accompany excision of the ranula.

The plunging ranula is a kind of ranula that goes over the mouth floor to the neck and other adjacent tissue. Sublingual gland is gently accepted as origin of plunging ranula. Plunging ranula develops commonly because of rupture of sublingual gland duct by trauma and extravasation of salivary secretion to the adjacent tissue. It is not true cyst so that there is no epithelium. And it consisted with thin connective tissue, inflammation cell infiltration and salivary secretion. Left without treatment, it can grow into the 10 cm more huge lesion. This report is a case of 73 years old female who was diagnosed as plunging ranula with review of literature. She presented 5 cm submandibular swelling at first. When surgery was delayed because of patient's condition, the lesion grew into the l2cm huge size. We performed excision of sublingual gland, submandibular gland and plunging ranula and had a good result without recurrence.

The plunging ranula or cervical ranula is amucous extravasation cyst of the sublingual gland. It is slightly common in females, shows no side preference, and is more prevalent in the second and third decades of life. It typically manifests as a painless, nonmobile swelling in the neck. The pathogenesis of plunging ranula is the discontinuities of the mylohyoid muscle in a position that would allow extravasation of sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophages stuffed with mucin. The correct diagnosis is essential for the most effective treatment, which is exicision of the sublingual gland. The plunging ranula must be differentiated clinically and histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst, lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor. We report a case and review the literatures, in our case, 23-year old man were diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent surgery via a cervical approach. The ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although total sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods.

Purpose: A plunging ranula is relatively uncommon and represents a mucus escape reaction occurring from a disruption of the sublingual salivary gland. It is a common condition found in young adults, even though the reported age range is 2 - 61 years. We report our experience of a complete excision of a plunging ranula via the intraoral and submandibular approach. Methods: A 23-year-old man had a large protruding mass in the right submandibular area. Initially, the protruding mass appeared bilaterally but the left side disappeared spontaneously. The MRI findings revealed a homogenous fluid attenuation mass in the submandibular space, suggesting a ranula. The sublingual gland was extirpated through the intraoral approach and the ranula excised totally via the submandibular approach. Results: The patient had an uneventful postoperative course without infection, paralysis and tongue sensory changes, etc. The pathology findings were characteristic of a pseudocyst without a lining epithelium or endothelium but with a vascular fibro-conective tissue wall filled with mucinous fluid. No recurrence was observed on the submandibular area during the 8 month follow-up period. Conclusion: The combined intraoral approach and submandibular approach is an effective and highly recommended method for sublingual gland extirpation and complete excision of a plunging ranula.
