Bilateral nasolabial cyst: a rare case.

Nasolabial cysts are rare non-odontogenic cysts characterised by their extraosseous appearance and are always located near to ala nasi. They are painless and located beneath the mucosa leading to soft tissue swelling and elevation of nasal ala. Bilateral nasolabial cyst is a rare occurrence. This case report describes the clinical diagnostic features and multimodal imaging appearance of nasolabial cyst with review of literature.

Recurrence rate of odontogenic keratocyst treated by enucleation and peripheral ostectomy: Retrospective case series with up to 12 years of follow-up

BACKGROUND: Odontogenic keratocysts have been reported with high recurrence rates in the literature so various treatment modalities from simple enucleation to resection have been performed to achieve the cure. The purpose of this retrospective study was to investigate the recurrence rate of odontogenic keratocysts (OKCs) treated by enucleation and peripheral ostectomy. MATERIAL AND METHODS: An electronic search of the database of the Hacettepe University, Faculty of Medicine, Department of Pathology, was undertaken to identify patients histologically diagnosed with OKCs treated at Department of Oral and Maxillofacial Surgery between 2001 and 2015. RESULTS: In total, 81 patients were studied. The mean age at the time of diagnosis was 42 years, and the male:female ratio was 1:0.7. OKCs were located primarily in the posterior mandibular region (41%). Twenty-seven patients were re-examined to determine the recurrence rate. The mean follow-up period was 5 years (range, 1-12 years). The recurrence rate was 14.8%. The relationship between location of the lesion and recurrence was not statistically significant (p= 0.559). There was also no statistically significant relation between the recurrence rate and treatment option of teeth involved in the lesion (p= 0.579). CONCLUSIONS: The authors conclude that treatment of OKCs by enucleation with peripheral ostectomy is associated with minimal morbidity and is preferred over other aggressive treatment modalities. Meticulous radiographic examination and careful surgical resection may decrease the recurrence rate of OKCs

A case report on a nasolabial cyst presenting with a nasolacrimal sac cyst.

Nasolabial cysts are rare, nonodontogenic soft tissue developmental cysts that occur in the maxillary lip and nasal alar regions. Patients with this type of cyst generally presents with an asymptomatic soft swelling that may obliterate the nasolabial fold, elevate the nasal ala or the floor of the nose and fill the labial vestibule intraorally. The exact origin of nasolabial cysts is uncertain. The seed theory suggests that these cysts develop from a misplaced epithelium of the nasolacrimal duct because of their similar location and histologic appearance. This report aimed to present a case of nasolabial cyst presenting with a nasolacrimal sac cyst.

A rare case of bilateral nasolabial cysts.

Nasolabial cysts are rare non-odontogenic cystic lesions representing around 0.7% of all maxillofacial cysts. They usually present as unilateral painless swellings, sometimes with epiphora and dacryocystitis as well as pain in cases of rapid growth or infection. We have reviewed the literature and present an extremely rare case of bilateral nasolabial cysts in a young Afro-Caribbean man presenting with chronic nasal blockage, epiphora and rhinorrhoea. We describe our successful surgical management using a sublabial approach for complete excision, leading to a disease-free outcome at 6 months follow-up. Other modalities have been described, from endoscopic marsupialisation to simple aspiration. However, with the exception of complete surgical excision, all other surgical techniques are associated with a high recurrence rate. We therefore advocate complete surgical excision as described below for optimal results.

Nasopalatine duct cyst, a delayed complication to successful dental implant placement: diagnosis and surgical management.

The dental literature reports frequently on both the success and survival of dental implants, whereby the focus remains on the biological response of hard and soft tissue to the implants. The predication and anticipation of adverse implant events can then lead to the preemption of implant loss. However, biological situations can arise that are outside the control of the clinician. The author reports a case history of the late manifestation of a nasopalatine duct cyst in close proximity to a dental implant and its subsequent surgical management.

Endoscopic endonasal marsupialization of nasopalatine duct cyst.

Nasopalatine duct cyst is one of the most common cysts among the nonodontogenic cysts in the maxillofacial area. This lesion usually does not show specific symptoms except for pressure from large cysts or infectious symptoms. Surgical removal including the epithelial lining is considered the treatment of choice. There are few reports of cases of endoscopic marsupialization treatment of large cysts, which have the risk of oronasal fistula. Here, we reviewed 3 cases of nasopalatine duct cyst treated with intranasal marsupialization and compared treatment results with those of conventional surgical enucleation. We suggest that endoscopic marsupialization could be used as an initial treatment option in selective cases.

Role of cone-beam computed tomography in diagnosis and management of nasopalatine duct cyst.

Nasopalatine duct cysts (NPDCs) are the most common nonodontogenic cyst of the jaw, with a reported prevalence of between 1% and 11.6% of all jaw cysts.1 It is believed to arise from epithelial remnants of the nasopalatine duct, the communication between the nasal cavity and anterior maxilla in the developing fetus. For huge NPDCs, total excision is difficult, and there is an increase in the possibility of postoperative complications including submucosal hematoma, wound dehiscence, wound infection, injury to tooth roots, injury to nasopalatine neurovascular bundles, paresthesia of the anterior palate, facial swelling, and oronasal fistula formation. This article discusses a case with a large NPDC, which was managed surgically without any complication. Radiological findings emphasizing the importance of cone-beam computed tomography in diagnosis and optimized treatment planning of NPDCs are discussed.

Nasopalatine duct cyst as a complication of dental implant placement: a case report.

This report demonstrates the association between the development of a nasopalatine duct cyst and implant surgery, involving 2 implants positioned 4 years after teeth extraction at a site unaffected by any prior local endodontic disease or radiolucency. The cyst was removed and the residual void was filled with deproteinized bovine bone. Two-year follow-up showed no cyst recurrence, the normal anatomy was partly restored, and one of the implants showed clinical signs of re-osseointegration.

Diagnóstico e tratamento do cisto nasolabial: relato de caso clínico / Diagnosis and treatment of nasolabial cyst: case report

O cisto nasolabial é um cisto de desenvolvimento não odontogênico raro, que acomete os tecidos moles entre a asa e base do nariz e o lábio superior podendo levar a assimetria facial. Sua patogênese é ainda muito discutida, no entanto, seu diagnóstico é clínico confirmado pelo exame anatomo-patológico. O tratamento clássico é a enucleação da lesão. O objetivo deste artigo é descrever as características, o diagnóstico e o tratamento do cisto nasolabial e relatar um caso clínico.

Nasolabial cyst is arare non-odontogenic development cyst, which affects soft-tissues between the ala and the base of the nose and the upper lip and may lead to facial asymmetry. Its pathogenesis is still controverse, although clinical diagnosis is confirmed by the anatomo-pathological examination. The treatment is enucleation of the lesion. The aim of this article is to describe the characteristics, diagnosis and the treatment of nasolabial cysts and report a clinical case.

Diagnosis and surgical management of nasopalatine duct cysts.

Nasopalatine duct cyst also known as nasopalatine cyst is a developmental, epithelial, non-neoplastic cyst that is considered to be the most common nonodontogenic cyst in the maxillofacial region. It is one of the many pathologic processes that may occur within the jaw bones, but it is unique in that it develops in only a single location--in the midline anterior maxilla. Nasopalatine cysts are usually asymptomatic and may be discovered during routine clinical and/or radiologic examination. The current study reports 18 cases of nasopalatine duct cyst that were diagnosed and treated at the Department of Oral and Maxillofacial Surgery at Ramadi Teaching Hospital, Anbar Province, Iraq. A correct diagnosis can only be made after proper clinical, radiographic, and histopathologic examination.

Large median palatine cyst.

Median palatine cyst is a rare fissural cyst of nonodontogenic origin located in the midline of the hard palate, posterior to the palatine papilla. Only 21 cases have been reported in the literature, and documented here is a median palatine cyst of the largest dimension thus far.A 14-year-old male patient presented with a 5 × 5-cm(3) mass distal to the palatine papilla of 5 years' duration. Magnetic resonance imaging revealed a 5.3 × 4.6 × 4.2-cm(3) cystic mass involving the midline of the hard palate. Complete enucleation of the cyst was performed with no recurrence, but an oronasal fistula developed 13 months postoperatively. A 1 × 4-cm(2) posteriorly based oral mucoperiosteal rotational flap was designed, raised, and transposed to reconstruct the palate. The oral mucoperiosteal flap was viable, and no sign of fistula was found 3 years postoperatively.Treatment of medial palatine cysts through enucleation is known to be relatively simple and curative. However, large lesions may lead to large defects that require a method of reconstruction and may also elicit bony defects in the hard palate, leading to an increase in postoperative complications such as oronasal fistulas.We report our experience of a large median palatine cyst, the largest documented to date, with a brief review of the literature.

Minimally invasive surgical approach in a large mandibular solitary cyst: case report and review of the literature.

Solitary bone cyst (SBC) is an intraosseus radiolucent lesions that defers from real cysts for the fact that peripheral epithelial lining is totally absent. It could be classified as a psudocyst and occurs most frequently in young patients. In most cases SBC doesn't cause symptoms and it is often diagnosed accidentally during routine radiographic examination. A right diagnosis of this disease is also complicated because there are no pathognomonic radiographic signs and symptoms: so this form of pseudocyst is often misdiagnosed as a common odontogenic cyst. Despite numerous studies, the pathogenesis of the SBC is not yet established: the most widely accepted theory is that it could be the result of an intramedullary necrosis determined by a trauma. In this article we report a case of SBC in child treated with a minimal surgical approach. This new kind of treatment is much more conservative than the traditional one, it can be performed as outpatients, under local anesthesia and with few postoperative discomfort: For these reasons this minimal invasive technique appears to be particulary suitable for pediatric patients.

A huge midline premaxillary cyst as a late complication of maxillary surgery.

A median palatal cyst is an uncommon nonodontogenic cyst, and patients usually present with a painless swelling or the sensation of a mass. The mass is typically a well-defined fixed swelling along the midline. The mass can cause slight elevation of the nasal floor or swelling and drainage from the hard palate. Surgical resection is usually recommended as a definite treatment.We treated a 30-year-old man with a premaxillary mass with nasal obstruction. He had undergone surgery on both the maxilla and the mandible to correct malocclusion 10 years earlier. A physical examination revealed elevated mucosa of the nasal floor, resulting in near-total obstruction of the nasal cavity, and the gingival mucosa over the upper incisors was also swollen. Preoperative computed tomographic scan demonstrated a midline nonenhancing round cystic lesion in the premaxillary area. Surgical excision was performed via a sublabial approach under general anesthesia, and his recovery after surgery was uneventful.

Diagnosis and surgical treatment of a nasolabial cyst.

Nasolabial cysts are uncommonly diagnosed nonodontogenic soft tissue lesions located close to the nasal alar region of the face, presenting as extraosseous swelling in the region of the nasolabial fold. Nasolabial cysts are likely to remain undetected unless and until they become infected or are associated with facial deformity. Histologically, it is lined with nonkeratinized squamous epithelium or, more frequently, with respiratory-type cylindrical epithelium with goblet cells. The aim of this article was to present and discuss the surgical management of a case of nasolabial cyst and to briefly review the literature.

Expansive nasopalatine duct cysts with nasal involvement mimicking apical lesions of endodontic origin: a report of two cases.

INTRODUCTION: The nasopalatine duct cyst (NPDC) is the most frequent nonodontogenic cyst of the jaws and can be misinterpreted as an apical lesion of endodontic origin. METHODS: In the first case, a 17-year-old male patient was referred because of a pressure sensation in the anterior maxilla. The teeth #7, #8, #10, and #11 responded to cold sensitivity testing, and on tooth #9 an endodontic treatment had been performed 3 years ago. Only periapical radiographs had been taken, and a radicular cyst was suspected. In the second case, a 42-year-old man reported inconvenience wearing his upper removable partial denture. Suspecting a jaw cyst in the anterior maxilla, the general dental practitioner referred the patient. RESULTS: Limited cone-beam computed tomography scans visualized the expansion of the cysts and the involvement of the neighboring structures in both cases. In both patients, the NPDCs were treated first by marsupialization in local anesthesia and second with cystectomy in general anesthesia with reconstruction of the defect areas with bone gained from the iliac crest. The final diagnosis was achieved by histopathological examination. CONCLUSIONS: If not diagnosed early, the NPDC can expand through the palatal and/or buccal cortical wall and also into the nasal cavity. The more expansive the NPDC is becoming, the more complex the final diagnosis is and the subsequent surgical therapy.
