ABSTRACTAmeloblastic fibroma (AF) is rare benign odontogenic tumour which usually occurs in the first two decades of life. It can occur either the mandible or maxilla but it is most frequently found in the posterior region of the mandible. Treatment of AF in usual is a conservative approach, such as enucleation and curettage but the aggressive lesions require a radical approach. A more radical approach should be considered in older patients who have likely high recurrence tendency. This report describes a case of AF in a 38-year-old female patient identified during a routine radiographic exam. Tomographic examination through three-dimensional reconstruction indicated vestibular fenestration of the cortical bone, with involvement of lingual cortical bone as the lession extended to the posterior region. We removed the tumor under local anesthesia. In this case patient has continued to be followed frequently and has been disease-free for 3 years.

ABSTRACTAmeloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting with extensive AF of the mandible. He underwent a conservative enucleation. The tumour recurred 2 years after the initial surgery, requiring the second enucleation.The patient has continued to be followed closely and has been disease-free for 4 years. Recent evidence suggests that the recurrent rate of AF is relatively high, and malignant transformation of AF may occur after recurrences or multiple surgeries. A conservative treatment approach with close surveillance is recommended. Anatomical limitations should be taken into account, especially when enucleation of AF in the posterior portion of the jaw is performed. Current surgical pathologic issues of the tumour are also discussed. (Eur J Dent 2009;3:224-228)

Ductus arteriosus aneurysm (DAA) in adulthood is a rare entity. We retrospectively reviewed our medical records from the past ten years and identified eight cases of adult DAA (six males and two females aged between 69 and 89 years; mean, 76 years), using multi planar reconstruction and three-dimensional reconstruction computed tomography (CT) images. The aneurysm was suspected incidentally in all cases based on the results of chest radiographic screening or postoperative follow-up CT for lung or colon cancer. All eight patients were asymptomatic but had a history of or concurrent hypertension (n = 5, 62.5%), diabetes mellitus (n = 3, 37.5%), cerebrovascular disease (n = 3, 37.5%), ischemic heart disease (n = 1, 12.5%), and cardiac failure (n = 1). All patients had no history of trauma (n = 8, 100%). Six had a history of cigarette smoking. The aneurysm size ranged from 2.0 × 4.0 to 6.3 × 5.3 cm (mean, 3 × 5 cm). The surgical procedures used were four cases of total arch replacement and two cases of thoracic endovascular aortic repair. Two patients were not surgically treated. The median follow-up was 14.5 months (range, 2 months to 9 years). In the two patients who were not surgically treated, the aneurysm enlarged in one, and remained unchanged in the other. Of the six cases surgically-managed cases, one was lost to follow-up, and another patient died of an unrelated cause. The remaining four cases had no enlargement of the aneurysm. No ruptures were reported in any of the cases. DAA should be considered when a saccular aneurysm is located in the minor curvature of the aortic arch and extending toward the left pulmonary trunk in adult patients. Differentiating adult DAA is important, because it is associated with a high risk of rupture due to the fragile nature of true aneurysms.

Joint Ankylosis

SummaryTemporomandibular joint (TMJ) ankylosis is characterized by difficulty or inability to open the mouth. The ankylosis may be articular (‘true’) or extra-articular (‘false’). Clinical signs, radiographic studies, treatment and follow-up are presented in a retrospective study involving five cats and five dogs. The findings were compared with TMJ ankylosis in humans. CT imaging with three-dimensional reconstruction proved to be of great value in determining the extent of the abnormalities and helped with preoperative planning. Articular TMJ ankylosis occurred in six animals and extra-articular TMJ ankylosis was found in the other four cases. In three cats and in three dogs, the TMJ ankylosis was trauma related; the remaining patients were diagnosed with a tumour. Resection of ankylosing tissue in false ankylosis or gap arthroplasty in true ankylosis was successful in all of the trauma induced cases. In the two cats, with tumour related ankylosis, the ankylosis was caused by an osteoma and resection had a good prognosis, whereas the two dogs had to be euthanatized.

AbstractA 14-year female presented with an atypical looking tooth #7 with a sinus tract on tooth #8. A gutta-percha point inserted into the sinus tract confirmed the affected tooth #7. A radiographic examination of tooth showed a lateral radiolucency with respect to tooth #7. Cone-beam computed tomographic imaging was done for the three-dimensional reconstruction analysis. Dens invaginatus (Oehler’s type III) with pulp necrosis and chronic apical periodontitis was the definitive diagnosis. Use of the dental operating microscope and ultrasonics helped in the removal of the invaginated structure. At the two year follow-up, no clinical and radiographic evidence of infection was observed.

AbstractObjective:To report a unique case of unilateral blindness secondary to transnasal endoscopic surgery and stenting for right choanal atresia.Case report:A 24-year-old man was referred with right eye blindness and acute headache, occurring immediately after transnasal endoscopic surgical repair of unilateral right choanal atresia with placement of an endonasal stent. Maxillo-facial computed tomography with three-dimensional reconstruction showed the endonasal stent entering the right nostril, passing through the lamina papyracea into the orbit and running anterior to the optic foramen towards the superior orbital fissure. Despite stent removal and medical treatment (ceftriaxone and dexamethasone), permanent right eye blindness secondary to an irreversible lesion of the optic nerve was diagnosed. At three-month follow up, an uncommon, complete fibrous obliteration of the right nasal fossa was noticed.Conclusion:To the best of our knowledge, this is the only published report of unilateral blindness following transnasal endoscopic stenting for right choanal atresia. Causes of this complication, and ways of avoiding it, are discussed.

Abstract Objective: This study evaluated the long-term efficacy of globus pallidus internus (GPi) deep brain stimulation (DBS) in the treatment of Cranio Facial dystonia (Meige syndrome) and investigated the correlation between the volume of tissue activated (VTA) of the GPi and each subregion and movement score improvement.Methods: We retrospectively analyzed the clinical data of 13 patients with drug-refractory Meige syndrome who were treated with GPi DBS. Pre- and postoperative Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) scores were compared. Relationships between preoperative baseline variables and improvement in the BFMDRS-Movement (BFMDRS-M) score were analyzed. LEAD-DBS software was used for three-dimensional reconstruction of the GPi and implanted electrodes. Correlations between the GPi-VTA and score improvement were analyzed.Results: The average follow-up period was 36.6±11.0 months (18-55 months). The improvements in the BFMDRS-M score were 58.2% and 54.6% at 3 months after stimulation and at the final follow-up visit, respectively, and the improvements in the BFMDRS-Disability (BFMDRS-D) score were 53.6% and 51.7%, respectively. At the final follow-up visit, the improvements in BFMDRS-M scores for the eye, mouth, and speech/swallowing were significant (P<0.001). Age was an independent predictor of improvement in the BFMDRS-M score after DBS (P=0.005). A decrease in the BFMDRS-M score had significant positive relationships with the GPi-VTA (r=0.757, P=0.003). Conclusions: GPi DBS is an effective method to treat drug-refractory Meige syndrome. LEAD-DBS software can be used as an effective aid for visualization programing after DBS.

Introduction. Although conventional cystoscopy is considered to be the gold standard for diagnosis and follow-up of bladder tumors, it remains an invasive and costly procedure. With the advent of the multidetector CT (MDCT) scanners supported by specialized software virtual cystoscopy (VC) is possible. We assess the role of VC in diagnosing and evaluating bladder lesions.Materials and Methods. Between September 2010 and October 2011, 25 consecutive patients with cystoscopically confirmed bladder tumor underwent VC. The radiologists involved in this prospective study were blinded to the exact findings. After draining any residual urine with a catheter, the bladder was retrogradely insufflated with 200–600 cc of air. No intravenous or intravesical contrast was used. MDCT scan was performed in supine and prone positions and three-dimensional reconstruction of the urinary bladder was performed.Results. The examination was well tolerated by all patients with no complications. In total, 43 lesions were detected both with conventional cystoscopy and VC. Tumor size measured by CT ranged from 3 to 80 mm in diameter. The pathological report revealed noninvasive transitional cell carcinomas in all cases.Conclusion. VC has promising results in detecting exophytic bladder lesions. In the future it could be part of the diagnostic algorithm for bladder tumors.
