Surgical treatment and follow-up of solitary bone cyst of the mandible:a report of seven cases.
2001
We have operated on and followed up seven patients with simple mandibular bone cysts. The clinical data are shown in Table 1. All cysts were asymptomatic, and were found as a result of routine radiographs. They were all in dentulous areas in the mandible (5 in the anterior zone). Only case 5 gave a clear history of trauma in the region of the cyst 7 years before diagnosis. Vitality of the pulp of adjacent teeth was confirmed in all cases except case 6, in whom endodontic orthograde treatment of the teeth included in the lesion zone had previously been done. In all cases, the radiographs showed a unilocular radiotransparent lesion with clearly defined margins
Three-dimensional images contribute to the diagnosis of mucous retention cyst in maxillary sinus
2011
Objective: To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). Study Design: A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned, and control panoramic radiographs were obtained 6 to 46 months after the initial radiograph. When MRCMS was found on control radiographs, CBCT scans were obtained. Cysts were measured and compared on radiographs and scans. The Wilcoxon, Spearman and Kolmorogov-Smirnov tests were used for statistical…
Prevalence and distribution of odontogenic cysts in Sicily: 1986-2005.
2008
The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, whereas only 37 were non-odontogenic. In the former group, the most frequent lesions were radicular cysts (84.5%), followed by dentigerous OCs (11.4%). Inflammatory radicular cysts were observed more in male gender, younger age at diagnosis and anterior maxilla as site of presentation. Unlike dentigerou…
Endoscopic and endoscope-assisted neurosurgical treatment of suprasellar arachnoidal cysts (Mickey Mouse cysts).
2005
Suprasellar arachnoid cysts represent less than 10% of all intracranial arachnoid cysts. Some of them may be quiescent throughout life, some may become symptomatic as they become enlarged and some disappear spontaneously. In this study we discuss the surgical strategies for endoscopic and endoscope-assisted treatment of suprasellar (Mickey Mouse) cysts and analyze the clinical results and experience collected over some years in our department upon doing these operations routinely. Between December 1996 and December 2003, 13 patients (7 female and 6 male patients), mean age 29 years, underwent endoscopic or endoscope-assisted procedures for suprasellar cysts at our department. The indication…
Improving the disease awareness: how a communication campaign brings hidradenitis suppurativa to the light
2019
Background: Hidradenitis suppurativa is an inflammatory skin disease that presents a recurrence of painful and suppurating lesions in the apocrine gland-bearing regions, with a strong impact on the patients’ life quality. Despite its peculiar presentation, early forms are often underestimated by patients and this would inevitably result in late diagnosis and delayed therapy. Objectives: Improved communication around the disease could facilitate self-diagnosis and a quicker response from healthcare practitioners, especially in this moment when we dispose of effective treatment against this disease. Methods: A HS awareness campaign was conducted for 2 years with the help of a media agency and…
The supracondylar approach to the jugular tubercle and hypoglossal canal.
1998
BACKGROUND Circumscribed lesions of the hypoglossal canal and of the jugular tubercle still remain a surgical challenge. So far, transpetrosal, transcondylar suboccipital, and extreme lateral approaches have been used to access this region. These surgical procedures bear a high risk for neurological deficits. Therefore, we introduce a new minimally invasive extradural approach to the hypoglossal canal that also allows access to the lateral aspects of the jugular tubercle. METHODS After a paramedian retromastoid skin incision, a basal suboccipital craniectomy lateral to the foramen magnum toward the jugular tubercle is performed. With this approach the occipital condyle and the lateral osseo…
Bolus-enhanced renal spiral CT: technique, diagnostic value and drawbacks
1994
Abstract In addition to pre- and postcontrast renal CT scans, early bolus-enhanced spiral scans during demarcation of the corticomedullary junction were acquired in 85 patients. The diagnostic value and drawbacks of the three imaging series in the evaluation of renal disease were assessed. Renal calcifications and calculus disease detected at precontrast scans (18%) were obscured after contrast administration and excretion in most cases. In the detection of renal lesions bolus-enhanced spiral CT and delayed postcontrast scans had an identical diagnostic yield (94%). Bolus-enhanced spiral CT was superior in the assessment of lesion vascularity and vascular anatomy as well as opacification of…
Are mucous retention cysts and pseudocysts in the maxillary sinus a risk factor for dental implants? A systematic review
2020
Background Mucous retention cysts and pseudocysts of the maxillary sinus are benign lesions present in up to 13% of adult patients. Different surgical approaches for sinus lift and dental implant placement in the presence of these lesions have been proposed. Material and Methods A systematic review was performed following the PRISMA statement recommendations to answer the PICO question: Does the aspiration or removal of mucous retention cysts/pseudocysts before or during sinus lifting and dental implant placing, affect the survival of the implants? The study was pre-registered in PROSPERO (CRD42020185528). Included articles quality was assessed using the “NIH quality assessment tool” and “T…
An observational retrospective study of odontogenic cyst´s and tumours over an 18-year period in a Portuguese population according to the new WHO Hea…
2020
Background Odontogenic cysts and tumours of the jaws represent one of the most prevalent groups of oral-maxillofacial lesions. We aimed to evaluate the clinical and pathological characteristics of a cohort of odontogenic cysts (OC) and odontogenic tumours (OT) of the jaws in a Portuguese population. Material and Methods This observational retrospective study analysed patients diagnosed with either an OC or OT of the jaws at a central hospital of Oporto, Portugal, between 1988 and 2006. Data collected from patients’ files included demographic, clinical, radiological and histopathological information. Recurrence was evaluated using univariate and multivariate analysis. Results The sample cons…
Mucinous cystadenomas and intraductal papillary mucinous tumors of the pancreas in magnetic resonance cholangiopancreatography.
2000
Background and Study Aims: In mucin-producing tumors of the pancreas, diagnosis using endoscopic retrograde cholangiopancreatography (ERCP) is limited to cystic formations that communicate with the main pancreatic duct. Magnetic resonance cholangiopancreatography (MRCP) is a new, sophisticated method which is currently under evaluation. The authors describe the usefulness of MRCP in diagnosis of mucin-producing tumors. Patients and Methods: Six patients with mucin-producing tumors were investigated using MRCP and ERCP. Imaging was compared with surgery and histopathological examinations. Results: Three patients were found to have mucinous cystadenomas (MC), two patients had intraductal papi…
