Bleomycin sclerotherapy following doxycycline lavage in the treatment of ranulas: A retrospective analysis and review of the literature.

OBJECTIVE: A ranula is a mucus-filled salivary pseudocyst that forms in the floor of the mouth, commonly arising from the sublingual or submandibular salivary glands following obstruction or trauma. Complete excision of the injured gland and removal of the cyst content is the first-choice therapy, but has the potential for complications related to injury to nearby structures. As such, minimally invasive approaches such as percutaneous sclerotherapy have been investigated. We aim to contribute to the literature by assessing the efficacy and safety of our technique through our experience with 18 patients over the last decade. METHODS: This retrospective study evaluated 18 patients with intraoral and plunging ranulas treated by percutaneous bleomycin ablation. The primary endpoint was the treatment result. Secondary endpoints included bleomycin dosage and complications. RESULTS: The study evaluated 12 males and six females with a median age of 23.5 years (range 13-39 years). At a final follow-up of at least 2 months (6.5±5.5 months), four patients demonstrated complete response (22%) and 14 patients demonstrated residual presence, recurrence, or regrowth of the lesion (78%). There were no statistically significant associations between outcomes and history of prior treatment, number of treatments, and size or type of ranula. No complications were noted. CONCLUSIONS: Our findings indicate that bleomycin, while safe for use in various head and neck malformations, is of limited utility in ranula therapy when the offending gland is not addressed primarily.

Sclerotherapy for Benign Cystic Lesions of the Head and Neck: Systematic Review of 474 Cases.

OBJECTIVE: The role of sclerotherapy for vascular lesions of the head and neck is well established. However, the efficacy of sclerotherapy for benign cystic lesions of the head and neck is less clear. The objective of this review is to determine the efficacy and safety of sclerotherapy for benign cystic lesions of the head and neck. DATA SOURCES: PubMed/MEDLINE, Cochrane Library, and Embase. REVIEW METHODS: The PRISMA guidelines (Preferred Reporting Systems for Systematic Reviews and Meta-analyses) were followed for this systematic review. Studies of patients with benign head and neck cystic masses treated primarily with sclerotherapy were included. Thirty-two studies met criteria for inclusion. RESULTS: A total of 474 cases of sclerotherapy were reviewed. Agents comprised OK-432, ethanol, doxycycline, tetracycline, and bleomycin. Lesions in the analysis were ranula, thyroglossal duct cyst, branchial cleft cyst, benign lymphoepithelial cyst, parotid cyst, thoracic duct cyst, and unspecified lateral neck cyst. A total of 287 patients (60.5%) had a complete response; 132 (27.9%) had a partial response; and 55 (11.6%) had no response. OK-432 was the most widely utilized agent, with a higher rate of complete response than that of ethanol (62.0% vs 39.4%, P = .015). Fifty-three cases (11.2%) required further surgical management. One case of laryngeal edema was reported and managed nonoperatively. CONCLUSION: Sclerotherapy appears to be a safe and efficacious option for benign cystic lesions if malignancy is reliably excluded. Efficacy rates are comparable to those of sclerotherapy for vascular malformations. The rate of serious complications is low, with 1 incident of airway edema reported in the literature.

Treatment of oral ranula in HIV-positive patient.

HIV-associated salivary gland disease refers to the pathology in head and neck lesions such as ranula, salivary gland swelling, xerostomia, and benign lymphoepithelial cysts in the parotid gland. Here, we present a unique case of the ranula patient with HIV infection treated with OK-423 sclerotherapy. Case report: The patient was a 42-year-old Japanese male with a few months history of oral floor swelling. Computed tomography (CT) showed a low-density area limited within the right floor of the mouth. Magnetic resonance imaging (MRI) revealed a distinct T2-high intensity area localized on the same location. The puncture fluid was bloody mucus, and the cytology was no malignancy. We diagnosed a simple ranula. He was, however, found to be HIV-antibody positive at the examination before treatment by chance. He was referred to the department of infectious diseases and definitively diagnosed HIV infection by western blot. We chose OK-432 sclerotherapy because of its minimally invasive and the risk of HIV infecting medical staff. Two times OK-432 injection made the lesion disappear. Conclusion: The case indicated that OK-432 sclerotherapy could be effective for ranula related to HIV.

Percutaneous treatment of ranulas: ultrasound-guided drainage with salivary gland chemical ablation.

BACKGROUND: Ranulas are salivary pseudocysts in the floor of the mouth adjacent to damaged salivary glands. Current surgical management is drainage of the ranula with removal of the offending gland. An analogous percutaneous procedure could potentially offer similar treatment efficacy in a more minimally invasive way. OBJECTIVE: To evaluate the outcomes of a cohort of patients with ranulas treated with percutaneous ranula aspiration and chemical ablation of the source salivary gland to see whether this technique could be proposed as a minimally invasive treatment alternative. MATERIALS AND METHODS: This retrospective single-center study evaluated 24 patients treated percutaneously for ranulas between January 2004 and December 2014. All patients were treated with percutaneous ranula aspiration and chemical ablation of the offending salivary gland. Treatment success and any complications were recorded. RESULTS: Complete ranula eradication was successfully accomplished in 87.5% of the patients with no complications. CONCLUSION: Initial results suggest that our technique of percutaneous aspiration of ranulas and chemical ablation of the source salivary gland is safe and effective.

Prenatal Diagnosis and Intrapartum Management of Congenital Ranula.

A foetal sublingual cystic lesion was diagnosed by routine prenatal ultrasonography at 27 weeks of gestation. Foetal growth and amniotic fluid volume were normal. An ex utero intrapartum treatment (EXIT) procedure was performed, and the cyst was aspirated to allow breathing during planned Caesarean section. The cyst was totally excised when the newborn was 60 days old, and histopathological examination revealed a mucous cyst of the mouth floor.

Plunging ranula - patient characteristics, treatment, and comparison between different populations.

OBJECTIVES: To review our clinical experience and characteristics of Finnish patients with plunging ranula and compare our results with reports from other populations. DESIGN: A retrospective study from the electronic hospital records between 2005 and 2016. SETTING: The Department of Otorhinolaryngology and Head and Neck Surgery of Helsinki University Hospital, Finland. RESULTS: We describe the characteristics and treatment of 41 patients with MRI-confirmed plunging ranula. Most of our patients were young adults and 88% of them were male. Surgery and sclerotherapy were used for treatment. CONCLUSIONS: The vast majority of Finnish plunging ranula patients in our cohort were male, suggesting significant population-related differences in plunging ranula gender distribution. Transoral surgery seemed to result in lowest recurrence rate and was the most common treatment in our clinic.

Successful ablation of plunging ranula by ultrasound-guided percutaneous ethanol injection.

Evidence supporting any one treatment for plunging ranula is limited. Standard treatment-complete excision of the sublingual gland and ranula-is invasive and morbid given the close operative proximity to the submandibular duct and lingual nerve. OK-432 (Picibanil; Chugai Pharmaceutical Co., Tokyo, Japan) sclerotherapy has been studied as a less invasive treatment but is inaccessible in the United States. This report illustrates the successful management of a plunging ranula using ultrasound-guided percutaneous ethanol injection. Within 2 months of the procedure, the patient had complete resolution of the plunging ranula, with no associated side effects. We propose that ultrasound-guided percutaneous ethanol injection be considered for the management of plunging ranula. Laryngoscope, 127:2239-2241, 2017.

Plunging ranula with prestyloid parapharyngeal space, masticator space, and parotid gland extension.

Plunging ranula with prestyloid parapharyngeal space, masticator space, and parotid gland extension. INTRODUCTION: Ranulas develop from mucous extravasation secondary to sublingual gland duct obstruction or trauma. Plunging ranula usually dive into the submandibular space. METHODS: This is the first reported case of a plunging ranula with direct extension to the prestyloid parapharyngeal space, masticator space, and parotid gland with avoidance of the submandibular space. RESULTS: The patient presented with a tender parotid mass, of which the differential is broad, including parotitis, parotid malignancy, metastatic malignancy, lymphoma, as well as other infectious etiologies. When an intraoral component is not identified, other differential considerations would be thyroglossal duct cyst, branchial cleft cyst, parathyroid cyst, cervical thymic cyst, dermoid cyst, cystic hygroma, or benign teratoma. CONCLUSION: The case is unique due to ranula extension into multiple spaces. For optimal treatment, the sublingual gland along with its tract and contents needs to completely removed.

[Plunging ranula. Review]. / Ranulas à expression cervicale. Mise au point.

INTRODUCTION: Ranula is a pseudocyst of the sublingual gland, often of unknown etiology. In few cases, it can extend to the neck when passing through the mylohyoid muscle. Diagnosis is not always easy as other cervical cystic lesions may have the same clinical aspect. Some ranulas recur after removal. The aim of our study was to conduct a review about plunging ranulas, with a focus on the most useful paraclinical exams and the most effective treatment. MATERIAL AND METHODS: A review of the literature has been conducted in the PubMed database between 2015 and 2010 using following keywords: plunging ranula, recurrent plunging ranula. RESULTS: Thirteen articles reporting 37 cases of plunging ranulas have been selected. Among these cases, 3 recurred. Paraclinical exams consisted in US, CT scan and MRI. Main reported treatment was sublingual gland removal, sometime associated with marsupialization. DISCUSSION: The most useful paraclinical exam is CT scan. Total sublingual gland removal is the most efficient treatment.

Salivary gland disorders.

Patients with salivary gland disease present with certain objective and/or subjective signs. An accurate diagnosis for these patients requires a range of techniques that includes the organized integration of information derived from their history, clinical examination, imaging, serology, and histopathology. This article highlights the signs and symptoms of the salivary gland disorders seen in the Salivary Gland Center, and emphasizes the methodology used to achieve a definitive diagnosis and therapy.

What is new in management of pediatric ranula?

PURPOSE OF REVIEW: Ranula is extravasation mucocele arising from the sublingual gland, influencing the swallowing or eating; this review focuses on the most recent literature pertaining to pediatric ranulas and aims to comprehensively describe the methods of diagnosis and management approaches. RECENT FINDINGS: Ranulas consist of intraoral ranula and plunging ranula, which are frequently misdiagnosed, so it is vital for the differential diagnosis of pediatric ranulas to depend on the clinical examination, imaging and fine-needle aspiration cytology. Pediatric patients should first be observed for 6 months before other treatments. OK-432 could activate inflammatory reaction to induce shrinkage of pediatric ranulas. Marsupialization, incision with drainage and ranula excision alone, are associated with a high rate of recurrence, even marsupialization with packing and modified micromarsupialization should be prudently applied for primary treatment of intraoral ranula. Laser excision is considered an alternative treatment for intraoral ranula of pediatric patients because of low recurrence rates and surgical complications. Recently, sublingual gland with or without ranula excision is a reasonable and suitable choice for radical treatment in pediatric patients. SUMMARY: The principal goal of pediatric ranula management is radical sublingual gland excision, sealing the mucus extravasates and lowest complications.

Successful medical treatment for ranula in children.

OBJECTIVES: We compare the outcome of medical treatment for ranula versus surgery in children. STUDY DESIGN: Multicentric cohort study. METHODS: The case series includes 37 children with ranulas (diameter 2.7 ± 1.5 cm). Eighteen patients, including 3 who had relapsed after either simple marsupialization or ranula removal alone, received oral nickel gluconate, mercurius heel, and glandula submandibularis suis D10/D30/D200. Fifteen cases underwent marsupialization with packing, and 2 underwent sublingual gland and ranula en-bloc excision. Two patients who recovered spontaneously shortly after diagnosis were excluded. RESULTS: No recurrences occurred among medical patients. Of the 17 surgical patients, 3 treated with marsupialization with packing relapsed. With the 3 surgical failures from other centers a total of 6 of 20 relapses were considered. Swelling or tension was common in surgical cases but unusual in medical patients. CONCLUSIONS: In this case series oral medical treatment for ranula was very effective and more effective than marsupialization with packing.

Ránulas intraorales en una población brasileña: estudio retrospectivo del empleo de la marsupialización modificada / Intraoral ranulas in a brazilian population: a retrospective study of the use of modified marsupialization

Las ránulas son seudoquistes resultantes de la extravasación salival de las glándulas sublinguales. Diversos tratamientos han sido empleados, no obstante, la marsupializaión se ha demostrado es el método más utilizado. La modificación de la técnica convencional, haciendo un taponamiento con gasas medicadas, presenta bajos índices de recurrencia, mientras su aplicación cuidadosa. El objetivo de este trabajo fue evaluar los resultados obtenidos por el empleo de la técnica de marsupialización modificada en los casos de ránulas intraorales diagnosticadas en el Servicio de Estomatología de la Facultad de Odontología de la Universidade Federal do Ceará, entre marzo de 1999 a diciembre de 2010, y comparar estos datos con estudios previamente reportados en la literatura. Los datos, tras su colecta, fueron tabulados y analizados estadísticamente (SPSS, versión 17.0). Del total de 2.103 biopsias, 17 (0.8%) correspondieron a ránulas intraorales, con edad comprendida entre 10 y 34 años de edad (media de 22,9 años), siendo 82,4 mujeres y 17,6 hombres. El tamaño de las lesiones varió entre 0,3 y 4 cm, con un promedio de aproximadamente 1,8 cm. La técnica de marsupialización modificada empleada en 13 pacientes, presentó un solo caso de recidiva. Otras dos recurrencias fueron observadas cuando se utilizó la técnica de la extirpación de la lesión, usada en cuatro casos. Nuestros resultados mostraron que la marsupialización, con cambio de la técnica convencional, es un método conservador eficaz, aunque no estadísticamente significativo (p>0,05), debiendo ser elegido como primera opción en el tratamiento de ránulas intraorales, con tasas reducidas de recurrencia.

Ranulas are pseudocysts as a result of salivary extravasation of the sublingual glands. Various treatments have been used, however, has been shown marsupialization the most used. The modification of the conventional technique, carefully filling of the lesion with gauze soaked in nitrofurazone (Furacin ®), have low rates of recurrence. The aim of this study was to evaluate the results obtained using the technique of marsupialization modified in the treatment of intraoral ranulas diagnosed in the Service of Stomatology, Faculty of Dentistry at the Universidade Federal do Ceará, from March 1999 to December 2010, and compare these data with previously reported studies in the literature. The data, after collection, were tabulated and statistically analyzed (SPSS, version 17.0). Of the total of 2,103 biopsies, 17 (0.8%) were intraoral ranulas, aged between 10 and 34 years of age (mean 22.9 years), with 82.4 men and 17.6 women. The lesion size ranged from 0.3 to 4 cm, with an average of about 1.8 cm. Modified marsupialization technique used in 13 patients, presented a single case of recurrence. Two other recurrences were observed when using the technique of surgical excision, used in four cases. Our results showed that marsupialization, with change of the conventional technique is an effective conservative approach, although not statistically significant (p> 0.05), must be chosen as first choice in the treatment of intraoral ranulas, with reduced rates of recurrence.

Pediatric oral ranula: clinical follow-up study of 57 cases.

OBJECTIVE: To present 57 cases of oral ranula in children, analyzing the clinical characteristics, treatment and outcome of these lesions. METHODS: The clinical histories of patients diagnosed with oral ranula, seen between 1998 and 2008 at the Oral and Maxillofacial Surgery Unit of a reference Children 's Hospital (0-14 years) were reviewed. All patients with clinical diagnosis of oral ranula were included. RESULTS: Fifty-seven patients, 21 boys and 36 girls, with a mean age of 5.1 years were included in the study. Thirty-two cases were located on the left side of the floor of the mouth. The lesion diameter varied between 1 and 3 cm in 27 cases, 22 were less than 1 cm, and 8 were larger than 3 cm. Fifty-four cases were asymptomatic and 3 ranulas had pain on swallowing. Twenty-two cases were resolved by opening with a tract dilator and 35 by marsupialization. Seven cases recurred at a mean of 12 months after treatment, three of these from the marsupialization group. CONCLUSION: The majority of the oral ranulas occurred in females, asymptomatic, on the left side of the floor of the mouth, with a mean size of 1 to 3 cm; all lesions were treated by surgery, of which 7 recurred.

Modern management and pathophysiology of ranula: literature review.

BACKGROUND: There is a lack of consensus about the appropriate treatment of ranula. The objective of the present investigation was to produce a scientific basis for treatment. METHODS: A review of the relevant literature is interpreted in the light of improved knowledge about the local anatomy and the pathophysiology of the salivary glands. RESULTS: The oral and plunging ranulas are cystic extravasation mucoceles that arise from the sublingual gland and usually from a torn duct of Rivinus. The sublingual gland is a spontaneous secretor and the salivary flow is resistant to obstruction, which is caused by fibrosis induced by the extravasation. The submandibular gland is not a spontaneous secretor, is less resistant, and does not give rise to ranulas. CONCLUSIONS: Effective treatment is removal of the involved unit of the sublingual gland or inducing sufficient fibrosis to seal the leak through which the mucus extravasates.

The therapeutic effect of OK-432 (picibanil) sclerotherapy for benign neck cysts.

BACKGROUND AND OBJECTIVES: In general, benign neck cysts are treated by surgical excision. This can present technical difficulties and frequent recurrences, because of insufficient surgery. Sclerosing agents such as OK-432 have been tested for the nonsurgical treatment of these cysts. We have assessed the efficacy of OK-432 sclerotherapy for benign neck cysts. MATERIALS AND METHODS: The study group consisted of 75 patients (42 men, 33 women) diagnosed with and treated for benign neck cysts between March 2001 and December 2007 by intralesional injection of OK-432. The liquid content of each cyst was aspirated as much as possible, and the same volume of OK-432 solution was injected. Patients were assessed by ultrasonography or computerized tomography, and therapeutic outcomes and adverse effects were evaluated by patient age, sex, cyst type, and number of injections. RESULTS: Of the 75 treated patients, 31 (41.3%) showed total shrinkage, seven (9.3%) showed near-total shrinkage (>90% of cyst volume), five (6.6%) showed marked shrinkage (>70% of cyst volume), and 17 (22.7%) showed partial shrinkage (<70% of cyst volume). No response was seen in 15 patients (20%). Despite repeated sclerotherapy, eight patients (10.7%) showed recurrences. Minor adverse effects of therapy included fever, localized pain, and odynophagia but these complications spontaneously disappeared within several days. CONCLUSIONS: OK-432 sclerotherapy is a safe and effective primary alternative to surgery in patients with benign neck cysts.
