A 15 months old male pit bull terrier was shown submandibular swelling, which was extended from left submandibular area through mandibular symphysis to right submandibular area and toward around left neck. In history taking, recurrence of swelling was recorded after conservative surgical incision, drainage and dressing. Palpation revealed no pain and heating, partial flutuation and hardness. By paracentesis, it was showed blood-tinged tenacious exudate without bad-smelling. Left submandibular salivary gland was able to be movable freely and the size decreased to half of that of right submandibular salivary gland. It was diagnosed as cervical salivary mucocele. In operation, rostral portion of left sublingual salivary gland was observed to be damaged transversely, showed black color and leaked saliva. Submandibular gland and rostral portion of sublingual salivary gland were resected, after ligation of ducts of submandibular and sublingual salivary glands. At 15 days postoperation, serosanguineous exudate from operation wound was dramatically decreased and stable granulation tissue mass at this area was first palpated. At 39 days after operation, outline of left and right mandibular was appeared normal and skin tenderness of mandibular area was equal to that of the other body wall.

Mucoceles of the minor salivary glands are the most common cystic lesions affected the oral mucosa. They are believed to be the result of trauma to the salivary duct caused, for example, by biting the lip, cheek, or tongue. Surgical excision has been the most common treatment for these lesions, but occasional recurrences develop after excision because surgical trauma may damage the surrounding minor salivary glands Although various alternative nonsurgical approaches, such as steroid infection, application of gamma-linolenic acid, have also been reported, they are not used routinely, Lasers, particularly the carbon dioxide laser, have been used in the management of mucoceles. Although this treatment requires specialized equipment. Cryotherapy is another effective nonsurgical method for treating mucoceles. Clinically, cryotherapy has primarily been applied to the treatment of leukoplakia and hyperplastic, granulomatous, vascular, and pigmented lesions. Limited information, however, is available on the application of cryotherapy in salivary gland lesions, including mucoceles. A simple and easy cryotherapy to treat a mucocele on the lower lip is described. A 25 years old female patient with a mucocele on the lower lip was treated by direct application of liquid nitrogen with a cotton swab. The lesion was exposed to 4 or 5 cycles composed of freezings of 10-30 s and thawings of double the freezing times. No anesthesia was required. The lesion nearly disappeared without scar 10 days after the cryotherapy. Cryotherapy has become an established nonsurgical method, characterized by its simple application, therapeutic effectiveness, painless during the procedure and low incidence of secondary infection and hemorrhage.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Mucoceles are categorized into two subgroups, extravasation type and retention cyst type. The etiology of extravasation type mucocele is related to mechanical trauma to the minor salivary gland excretory duct, resulting in extravasation of mucus into the fibrous connective tissue so that a cyst-like cavity is produced, but the epithelial lining is absent. Retention cyst type mucocele results from obstruction of minor salivary gland excretory duct, and cystic cavity is lined by epithelial cells. This case report presents a mucocele occurred on the lower lip, and caused by suture silk unremoved for 3 years. Suture silk penetrated and tore the minor salivary gland duct on the lower lip with subsequent extravasation of mucus into the fibrous connective tissue.

Mucocele is a mucous retention phenomenon which is caused by a laceration to the duct of minor salivary glands causing extravasation of mucin into the connective tissue forming a cyst-like space. Sialolithiasis of minor salivary glands and chronic obstruction of salivary glands may also cause such a phenomenon. Mucocele is a smooth, rounded sessile mass with diameters varying from 1 to 15mm of sudden appearance. Mucocele tying directly beneath the mucosa may rupture spontaneously and decrease in size, but frequently recurs. Lower lip is most frequently affected, and the mouth floor and buccal vestibule may also be affected. Enucleation of the cyst is needed and removal of minor salivary glands, marsupialization and cryotherapy may also be done. The mucocele frequently recurs after its removal. A 1-year-old female patient visited the hospital with a complaint of a swelling on the lower lip since 4 months before. She had no pain history but 4 months ago, fell and such symptom appeared since then. On her first visit, a bullous solid, opaque lesion of 5mm in diameter was noted. Treatment choice of surgical approach and nonsurgical approach were explained to the guardian. Considering the patient's age, the guardian agreed to a nonsurgical procedure. Treatment was carried out by tieing 3-0 silk to the base of the lesion. One week later, the tie loosened and was re-tied. A week later, the mucocele disappeared. Mucocele on the lower lip may be usually be treated by surgical removal, but this may traumatize the surrounding minor salivary gland causing it to recur. Also, surgicial removal may induce an ischemic change causing sialometaplasia. In case of young patients or children with management problems, non-surgical methods such as this tie method may be used. This tie method does not need any local anesthesia and has no pain, no secondary infection, and low bleeding tendency.

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.

A mucocele is a thin-walled, bluish, fluctuant swelling occurring just beneath the oral mucosa and filled with mucoid material. It usually results from damage to a salivary gland following which there is extravasation of mucus into the tissues, or occasionally it forms from dilatation of the duct of a salivary gland. The accepted treatment of a mucocele is excision of the sac and the associated minor salivary gland. Use of the $CO_2$ laser in oral surgery has several advantages. It is a very precise means of cutting tissue and causes little adjacent nontarget tissue damage. There is excellent coagulation of small blood vessels and consequently operative hemorrhage is greatly decreased. There is instant sterilization of the operative site, which decreases bacteremia. The operation sites were completely healed without any infection or complication and discomfort from swelling or pain was not noted in all cases throughout the healing process. In addition, following this therapy, there is little contraction or scarring.

Mucocele is a clinical term of the localized superficial mucosal swelling caused by salivary retention after the obstruction or the rupture of minor salivary ducts. Various treatment methods have been suggested to lower its recurrence rate, including complete excision of lesion Biopsy punch can be used easily and simply for complete excision of mucocele. It has several advantages, such as convenience in use, low bleeding tendency, and nearly no requirements for post-operative management. In this case, biopsy punch was used for the removal of mucocele in an uncooperative child, which enable fast, simple and safe procedure, with a good result.

Mucoceles are common benign cystic lesions of the oral cavity that develop following extravasation or retention of mucous material from the major or minor salivary glands. Mucoceles are usually located in the lower lip (60 to 70% of cases), and the floor of the mouth is only involved in 6 to 15% of cases. Submandibular gland mucocele is extremely rare but should be considered in the differential diagnosis of swelling at the submandibular triangle in young children. We present the rare case of a 16-month-old child who was diagnosed with bilateral submandibular gland mucocele, presenting as serial swellings in both submandibular regions. We removed the cystic mass with the submandibular and sublingual glands to prevent recurrence.

Minor salivary gland sialolithiasis (MSGS) is a not uncommon oral mucosal disease. Its clinical appearance may mimic a mucocyst or other benign submucosal overgrowth. Stasis of saliva, which accompanies MSGS, usually results in minor salivary gland inflammation, with a chronic sialadenitis appearance. MSGS typically is a painless lesion but can become painful when the salivary gland parenchyma or excretory duct becomes infected, with or without pus. However, misdiagnosis of this condition is rather common, as the clinical appearance is asymptomatic. The most common location is the upper lip, and MSGS affects males and females, with a slight predilection for males. The sialolith causing MSGS may be obvious during surgical excision, as in the case reported. In other cases, sialolith may be absent or fragmented. Differential diagnosis includes mucocele, swelling due to local irritation like fibroma and diapneusia, chronic abscess of the oral mucosa, and neoplasms either benign (lymphangioma, pleiomorphic adenoma) or malignant. Histopathological examination is needed to establish clinical diagnosis.
