Diagnostic Difficulties of Plunging Ranula: A Review of 18 Cases. Despite advancements in imaging techniques and cytological analysis, plunging ranula remains a challenging surgical, radiologic, and pathologic phenomenon. Of the 18 patients we evaluated at our institution, we highlight three cases that illustrate the high rate of misleading imaging and cytological results when assessing plunging ranula. Imaging results, biopsy findings, operative techniques, and pathological reports were reviewed from patients who had either a preoperative or postoperative diagnosis of ranula and underwent surgery by a single head and neck surgeon at a tertiary care center. Of the 18 identified patients, computed tomography was correct on preoperative imaging 73% of the time and magnetic resonance imaging

Sclerotherapy for the intraoral ranula with bleomycin: technical considerations and preliminary experience. Ranula is a mucous cyst that occurs in the sublingual gland (SLG) in the floor of the mouth. It can be classified into two types based on origins: One is the the lesser sublingual gland (LSLG) in the anterior segment and the Rivini duct, which is connected to it, and the other is the greater sublingual gland (GSLG) in the posterior segment. Because of the anatomical characteristics, surgical resection of the cysts carries the risk of damaging adjacent tissues and has a high recurrence rate. Intralesional injection of sclerotherapy may be a better alternative treatment. We summarized 65 cases of ranula treated with intralesional injections of bleomycin(BML). According to the origin

Ethanol Ablation of Ranulas and Risk Factor Analysis for Recurrence. Ethanol ablation (EA) was shown to be safe and effective for treating ranula, but few studies have assessed long-term outcomes and recurrence of ranula after EA. To evaluate the long-term outcomes and the risk factors for recurrence and receipt of subsequent surgery in patients who underwent treatment with EA for ranula . This case-series study was conducted at a single tertiary hospital and assessed patients who were treated with EA between July 2009 and March 2021. Among 70 consecutive patients, those with follow-up loss or who were followed up for less than 24 months were excluded. EA for ranula. The primary outcome was recurrence at last follow-up after single or multiple EA sessions. Secondary outcomes included

Amylase as a Diagnostic Tool for Plunging Ranula: Clinical Series and Description of the Technique. This study describes a technique of measurement for neck cyst amylase content and reviews the experience of a tertiary referral center for cases of suspected plunging ranula. A retrospective study was performed at the Manukau Surgical Center in Auckland, New Zealand. Patients with a possible diagnosis of plunging ranula based on clinical presentation and diagnostic aspiration of the cyst contents were included. Demographic data, imaging and laboratory findings were collected, along with findings from surgery and histology. The technique for measuring the amylase of the aspirated cyst contents was also carefully recorded. The 37 cases of confirmed plunging ranula included in this study had

The piercing-stretching suture technique for the treatment of simple oral floor ranula. Oral floor ranulas are pseudocysts located in the floor of the mouth that result from the extravasation of mucus from a sublingual gland. Historically, there has been little consensus on the ideal first-line treatment. Currently, definitive treatment involves sublingual gland excision, which can injure ; post-operative sialendoscopy was conducted in two paediatric patients. The surgical procedure was successful in all patients, and complete recovery of the ranula was seen in all but one of the patients who underwent suture replacement. No major or minor complications were encountered. This minimally invasive procedure may be considered a reliable and first-line treatment for management of simple oral

Sclerotherapy of ranulas with OK-432 - a prospective, randomized, double-blinded placebo-controlled study. Ranula is a rare benign cystic lesion in the floor of the mouth, which can herniate through the mylohyoid muscle and become a plunging ranula. Treatment for ranulas is currently surgical excision of the sublingual gland. Sclerotherapy with OK-432 is a well-established treatment of lymphatic malformations, but not yet thoroughly evaluated on ranulas. Objectives: To evaluate sclerotherapy of ranulas with OK-432 in a randomized double-blinded trial. 20 patients with plunging or intraoral ranula were randomized to two double-blinded injections with OK-432 or saline. Effect on the ranula and evaluation of symptoms and QOL were investigated. Treatment response differed significantly between OK-432

The importance of sublingual gland removal in treatment of ranulas: A large retrospective study. Investigate the efficacy of sublingual gland removal for the treatment of simple and plunging ranulas. After IRB approval, a retrospective review was performed on patients treated for a ranula from February 2013 to May 2018 at Texas Children's Hospital in Houston, TX. Clinical data was collected from medical records and patients were contacted in November 2018 to obtain additional information about recurrences or complications. This study included 52 patients with ranulas (10 plunging, 42 simple; M:F 21:31) with a mean age of 9.68 years. Eighteen patients provided information in the extended follow-up period. Simple ranulas were treated with intraoral excision of the cyst and the sublingual gland

The anatomical basis and rational for the transoral approach during the surgical excision of the sublingual salivary gland for the management of plunging ranula. The aim of this study was to illustrate and confirm that the complete intraoral excision of the sublingual gland alone, is anatomically the most rational approach, for the management of plunging ranula. We retrospectively reviewed clinical charts of diagnosed HIV-infected patients presenting with plunging ranula. The intraoral approach was used for the complete excision of the sublingual gland with evacuation of the pseudocystic content only. Neither extra oral approach, nor ranula dissection / drainage was performed. The surgical procedure was performed using local anesthesia. Pre- and postoperative MRI-scan investigations were

Bilateral Plunging Ranulas in South Auckland: Evidence for a Genetic Basis. We present a series of bilateral plunging ranula patients to examine the etiology, diagnosis, treatment, and prognosis of this condition. A retrospective chart review was performed on all cases of plunging ranula treated at the Department of Otolaryngology-Head and Neck Surgery, Counties Manukau District Health Board , New Zealand, between 2001 and 2019. There were 17 patients with bilateral plunging ranulas from a total of 187 plunging ranula patients. Eight patients were of Pacific Island descent; six were Maori; and three were Asian. There were no European patients with bilateral plunging ranulas. There were three types of bilateral plunging ranula patients: 1) Metachronous plunging ranulas-Five patients

Plunging ranula with lingual nerve tether: Case report and literature review. Plunging ranulas are most often treated surgically; various surgical approaches may be necessary depending on the unique characteristics of each case. Here, we present the case of a plunging ranula noted on imaging to have a cordlike tether, which was revealed intraoperatively to be the lingual nerve. This case illustrates the importance of preoperative imaging for surgical planning, and when a transcervical approach may be the best choice for plunging ranulas.

Sublingual gland excision for the surgical management of plunging ranula. A plunging ranula is a pseudocystic collection of mucin extravasated from the sublingual gland into the floor of mouth and through the mylohyoid muscle into the neck. While the lining of a ranula is non-secreting and resection of the sublingual gland is adequate for simple sublingual mucoceles, many surgeons attempt to address plunging ranulas with extensive transoral and transcervical dissections. We review our experience managing plunging ranulas with intraoral sublingual gland excision and ranula drainage alone. This is a case series of patients with plunging ranulas who underwent transoral sublingual gland excision and ranula drainage in the past 10 years at the Massachusetts Eye and Ear. All ranulas were

Plunging Ranula in a 78- year- old Male – a Rare Case Report The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis of plunging ranula is based

Ranula: Current Concept of Pathophysiologic Basis and Surgical Management Options. There is no consensus opinion on a definitive surgical management option for ranulas to curtail recurrence, largely from the existing gap in knowledge on the pathophysiologic basis. To highlight the current scientific basis of ranula development that informed the preferred surgical approach. Retrospective cohort study. Public Tertiary Academic Health Institution. A 7-year 7-month study of ranulas surgically managed at our tertiary health institution was undertaken-June 1, 2008-December 31, 2015-from case files retrieved utilising the ICD-10 version 10 standard codes. Twelve cases, representing 0.4 and 1.2% of all institutional and ENT operations, respectively, were managed for ranulas with a M:F = 1:1

Excision of sublingual gland as treatment for ranulas in pediatric patients. The aim of this case study is to demonstrate that post-operative complication rates of sublingual gland excision for treatment of ranulas are equal to or less than alternative methods with a lower recurrence rate than other surgical methods. This was a retrospective review of pediatric patients from 2004 to 2015  at Children's Hospitals and Clinics of Minnesota. Sixteen ranulas and 6 plunging ranulas were treated via sublingual gland excision during this time frame. Data examined included age, gender, scans of the lesion, location and size of lesion, surgical procedures, complications, and recurrence. There were 22 patients who met criteria. Only one patient had recurrence of the lesion (4.5%). One patient reported

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

Plunging ranula: surgical management of case series and the literature review Plunging ranulas are rare; report of this condition is particularly limited in our environment. We present case series in children; with all cases having both oral and cervical components. It is important to note this type of presentation of plunging ranula and their appropriate management.

Ancient schwannoma in the sublingual space masquerading as a plunging ranula Ancient schwannomas are benign, slow-growing tumours derived from the neural sheath. They are characterized by degenerative changes which are not seen in the common schwannoma. An unusual case of ancient schwannoma of the sublingual space is reported to highlight the diagnostic challenge that this tumour presents. A 49 -year-old male patient presented with an 8-month history of a right-sided neck swelling, palpable in the anterior part of the submandibular triangle. Pre-operative imaging showed a non-enhancing mass in the sublingual space spilling into the submandibular triangle, consistent with a plunging ranula. Fine needle aspiration cytology was inconclusive. However, histopathology of the lesion confirmed

Pediatric epidermoid cysts masquerading as ranulas: A case series. Pediatric neck masses represent a variety of differential diagnoses. A common pathology in pediatric cystic neck tumors include ranulas, mucus retention cysts due to salivary gland obstruction. Epidermoid cysts are lesions infrequently encountered in the pediatric population and may appear similarly to ranulas on computed tomography imaging. MRI more easily differentiates these masses, and should therefore be the preferred imaging modality. Due to their distinct intraoperative management, ranulas and epidermoid cysts should be distinguished preoperatively through proper workup.

The epidemiology of plunging ranula in South Auckland. Estimate the incidence rate and provide basic descriptive epidemiologic characteristics of plunging ranulas in a multi-ethnic population. Case series with chart review. The study group comprised all Counties Manukau Health (CMH, Manukau City, Auckland, New Zealand) patients presenting to the CMH Department of Otolaryngology with a diagnosis of plunging ranula from January 2001 to December 2013, as recorded in the departmental case register. Non-CMH domicile patients were excluded. South Auckland comprised the base population, as serviced by CMH. The 2006 New Zealand census data was used for population demographics. A total of 134 cases of plunging ranula were identified. The overall annual crude incidence rate was 2.4 per 100,000 person-years

Are the patients with anatomic variation of the sublingual/Wharton's duct system predisposed to ranula formation? To evaluate ranula development according to anatomic variation of the ductal system of sublingual gland (SLG), especially the presence of Bartholin's duct. The anatomic variation of SLG duct was prospectively investigated and compared between 55 consecutive patients with ranulas treated by SLG excision (group 1) and another 15 consecutive patients undergoing similar surgeries for other conditions (group 2). The ductal structures of SLGs and submandibular glands (SMG) were also compared between the pediatric patients and adult patients with ranulas. In 32 of 55 patients with ranulas (58.2%) and 1 of 15 patients without ranulas (6.7%), the SLG showed an anatomic variation
