Running title: A plunging ranula extended into parapharyngeal space Ranulas are lesion of sublingual gland origin, which occur in the floor of the mouth. Most ranulas, whether simple or plunging, are pseudocysts without and epithelial lining and ranulas have higher levels of salivary amylase and protein content. They can be classified into two types based on their extent: simple ranulas, confined to the sublingual space and plunging ranula which extend into adjacent spaces. Plunging ranula requires differential diagnosis with other lesions (neuroma, monomorphic adenoma, hemangioma, lipoma, dermoid cyst, lateral cervical cyst). The patient was diagnosed as plunging ranula. We experienced 17 years old male, visited to our department, who complain Rt. cervical swelling and in MRI view, this lesion involved sublingual, submadibular, parapharyngeal, skull base. We experienced a rare case of plunging ranula, extended into parapharyngeal space. We report the case.

Sublingual resection is known as the most effective treatment of choice to prevent recurrence in patients with plunging ranula. In this case report, we present our experience with a 37 year-old man with prolonged upper neck mass diagnosed as plunging ranula. He had persisting mass lesion even after 4 times of sclerotherapy. Due to fibrotic change the pseudocyst could not be drained after removing the sublingual gland. To resolve the mass lesion, ultrasonography guided transoral drainage was performed. Intraoperative ultrasonography may be useful for transoral drainage of plunging ranula difficult to approach after sublingual resection.

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.

하마종은 구강저에 발생하는 점액 낭종으로 주로 설하선과 관련된다. 즉, 하마종은 설하선 분비도관의 파열로 인하여 타액이 분비도관에서 빠져나와 주위의 연조직 내에 저류됨으로써 발생하는 가성 낭으로 정의되며, 원인은 설하선 도관의 파열이나 폐색이다. 하마종의 임상소견은 청색의 투명한 종창이 구강저의 소대를 중심으로 편측으로 발생하며, 무통성이며, 촉진시 파동성을 나타낸다. 조직소견은 결합 조직 내 와동이 형성되지만, 낭 벽은 상피세포가 아닌 육아조직으로 구성되는 가성 낭을 관찰할 수 있다. 하마종의 첫 번째 치료법으로는 하마종의 내벽이 구강점막의 일부가 되도록 만들어 주는 조대술을 고려할 수 있다. 본 증례는 특징적인 하마종의 임상소견을 보이는 환아에게 gauze-packing등을 동반한 조대술을 이용하여 치료한 증례로써 양호한 치료결과를 보여 보고하고자 한다.

A ranula is a pseudocyst that originates from the sublingual gland after trauma. Acute cases of ranulas that progress rapidly and cause respiratory distress are rare. Holoprosencephaly is a complex brain malformation caused by incomplete cleavage of the prosencephalon. Children with holoprosencephaly may experience upper airway obstruction due to the associated dentoalveolar malformations and oromotor dysfunctions. We present the case of an eight-year-old female patient with holoprosencephaly and a plunging ranula that manifested as an acute course due to difficult airway management. She required gastrostomy for oromotor dysfunctions related to feeding and swallowing and difficulty managing oral secretions. The sublingual gland and ranula were removed under general anesthesia. Postoperatively, urgent reintubation and close monitoring in the intensive care unit were required due to upper airway obstruction. We successfully managed the patient with close cooperation of a pediatrician and an anesthetist, and no recurrence was observed at the one-year follow-up. A ranula can be caused by trauma to the floor of the mouth in association with lingually inclined mandibular teeth, a type of dentoalveolar compensation seen in maxillary hypoplasia associated with holoprosencephaly. Careful consideration is needed in such cases since airway management can be difficult due to postoperative swelling and oromotor dysfunctions.

The authors experienced a non-painful, elevated, dome-shaped lesion on lower lip in Korean male of 22-year-old and a non-painful, elevated, dome-shape lesion on left side of mouth floor in Korean female of 36-year-old. And diagnosed the lesions as a mucocele and a ranula respectively, based on the comprehensive evaluation of data obtained from history taking, clinical and radiologic examination and histopathological findings. In these cases, the authors removed mucocele and ranula using the pulsed Nd:YAG laser with advantage of good hemostatic effect, and so we could minimize improper tissue destruction during operation. The excisional wounds of lower lip and mouth floor had a good healing process without any symptom of pain and any signs of bleeding and infection.

A plunging ranula is a pseudocyst caused by mucus secreted from the sublingual glands, and it is mainly observed on the mouth floor. Nowadays, sclerotherapy using picibanil has been performed instead of invasive surgical treatment, and studies are reporting safe and effective outcomes. In our study, more than 92% of the 25 patients had marked response after picibanil sclerotherapy, and no serious complications were observed. Picibanil sclerotheraphy can be considered as the primary treatment of plunging ranula for patients who refuse surgery under general anaesthesia.

Background and Objectives: A plunging ranula represents a mucus escape reaction occuring because of the disruption of the sublingual salivary gland. It is commonly a condition of young adults, although the reported age range is 6-43 years. There is said to be a slightly female preponderance of about 1.9:1(F:M). Surgical incision has been considered the definite treatment, but sometimes complete excision is very difficult. Non-surgical treatment of these lesions has been attempted, but the results have not been satisfactory. In this study, we present our experiences with picibanil (OK-432) sclerotherapy for a plunging ranula. Materials and Methods: We retrospectively reviewed 41 patients who have undergone sclerotherapy with picibanil for plunging ranula. Information was collected on age, sex, a number of injection, post-sclerotherapy side effect and outcome of treatment. Results: 17 patients (41.5%) showed a complete response, and 20 patients (48.7%) showed inter-mediate response. No response was seen in 4 patients (9.8%). As a side effect of intracystic OK-432 injection therapy, fever (26.8%) and pain(39.0%) were observed. However, fever and pain disappeared after several days in all cases. Conclusion: The results are showing that OK-432 injection is an effective and safe treatment for plunging ranula.

하마종은 구강저에 발생하는 점액 낭종으로 타액선 분비도관의 파열로 인하여 점액이 연조직 내에 저류되어 생기는 가성낭종이다. 구강저의 설소대를 중심으로 편측으로 발생하며 무통성이고, 병소의 크기가 증가함에 따라 피막이 얇아져서 청색의 투명한 종창이 되는 것이 특징이다. 병소의 크기가 큰 경우에는 연하 및 발음, 저작시 문제를 야기할 수 있지만 외부로 종창이 생기거나 감염되는 것은 드물다. 하마종의 치료법으로는 자발적으로 치유되는 것을 관찰하는 방법, 단순 절개 배농, 조대술, 절제술 등이 있다. 치료법 중 하나인 조대술은 낭벽의 일부분을 제거하여 구강 점막과 연결시켜주는 술식으로 보존적이며 소아에서 추천되는 방법으로 구강내 조직의 외형을 원형대로 유지할 수 있고, 해부학적 구조물을 손상시킬 위험성이 적은 장점을 가진다. 치료 후에 자주 재발될 수 있으며, 술 후 4개월 이내에 일어난다. 이 증례는 하마종을 주소로 내원한 8세 여아에서 조대술을 시행하고 관찰하였으며 재발소견 없이 정상적인 소견을 보인바 보고하는 바이다.

설하 점액류 1례와 하마종 2례를 각각 담열(痰熱)과 어열(瘀熱)로 변증하여 온담탕과 도홍사물탕을 처방해 호전을 보였으며, 장기 관찰에서 재발하지 않아 한약 치료가 구강 점액류 치료의 대안이 될 수 있으리라 판단된다.
