226 Angina bullosa haemorrhagica—a review of 14 cases M.R. Volkweis, S. Galeazzi, B. Trevisan ∗ Grupo Hospitalar Concei¸cão, Porto Alegre, Brazil
This article describes 14 cases of angina bullosa haemorrhagica. Angina bullosa haemorrhagica is a pathology restricted to the oral mucosa, commonly observed on the soft palate. It is characterized by a bloody bubble without systemic blood diseases associated or any other known illness related. The expression angina is used because the lesion can produce a chock sensation in the patient. The prognosis is good and the treatment is only symptomatic, avoiding secondary infection and improving the wound healing. That is a retrospective study performed on the records of clinical reports of the out patients clinic in fourteen cases diagnosed as this pathology. This lesion represents 1.5% of all the lesions observed during three years. The average age was 53 years, prevalence in females and the soft palate is the most common gender and anatomical location found. No alteration of blood exams was found in any patient. The clinical diagnosis can be easily achieved. Blood exams are recommended to eliminate the possibility of associated pathologies. Mouthwash with clorexidine was efficient to improve the wound healing. Conflict of interest: None declared. doi:10.1016/j.ijom.2011.07.489
227 Conservative treatment of the unicystic ameloblastoma: report of a case J.L. Silva Toro ∗ , H.D. Ghersi Miranda, E.A. Cabrera Gomez Oral and Maxilofacial Surgery, Universidad Peruana Cayetano Heredia, Lima, Peru
The ameloblastoma is defined as a locally aggressive and invasive tumor with a high capacity for recurrence. This aggressive and invasive behavior raises the question of conservative or radical choice of treatment, functional disorders, cosmetic and psychological results in the latter. Unicystic ameloblastoma is described as a lesion with specific morphological tables, a less aggressive biological behavior than the common ameloblastoma and a lower recurrence rate compared to conservative therapy, so we have a
case managed in the Department of Oral and Maxillofacial Surgery of the Peruvian University Cayetano Heredia in Lima, Peru, of a 9-year-old female with a facial asymmetry at the expense of a tumor in the left mandibular body of two months of evolution. It was decided immediately after admission to our institution incisional biopsy with aspiration with slim needle, obtaining a pathological diagnosis of type unicystic luminal ameloblastoma. Continues to be handled after 9 years with a procedure called marsupialization with curettage after a second surgical procedure and is demonstrated by the clinical and radiographic evaluation the non-recurrence of injury, having a disease-free tissue. The purpose of this research is to demonstrate the different methods of conservative treatment for the unicystic ameloblastoma demonstrating the service experience of our long-standing treatment that has shown great therapeutic effectiveness with a low recurrence rate at the end showing a treatment with less morbidity for the patient.

228 Complication prevalence in total resection of sublingual glands in ranulas: experience in a service of maxillofacial in Chile M. Barreda 1,2,∗ , G. Martinovic 1 , L. Canto 1 , S.

Introduction: Ranulas are lesion over the sublingual gland due to mucous retention in the ductal system or mucous extravasations resulting from rupture of the duct of the same gland. The main causes are trauma or obstruction of the ductal system, generating a higher incidence of this disease in children and young adults. Treatment for this condition is varied remains controversial. The technique that has shown less percentage of recurrence appears to be the total resection of the sublingual gland. Purpose: The aim of this study was to determine the prevalence of complications in ranula’s treatment under total resection technique of the sublingual gland. Materials and methods: A retrospective study of 20 patients operated in the Hospital Salvador of Santiago (Chile), between the years 2005 and 2009. Age and gender of the patients, postsurgical followup period of at least 3 months, neurological
1171
complications of the lingual nerve, injury to the duct of Wharton and recurrence of the injury were assessed. All specimens were subjected to histopathological analysis. Results: The patients were on average 17.25 years and there were 12 females and 8 males. From all patients studied only one had a relapse, representing a 1.6% of complications. Conclusions: Removal of sublingual gland represents an effective treatment with low morbidity rates. Thus, it should be chosen as first-line option in sublingual ranula management.

Aneurysmal bone cyst (ABC) is an expansive osteolytic lesion composed of variable sized spaces filled with blood, and it is considered a type of giant cell lesion. The prevalence is 1.4 per 100,000 individuals, representing about 1% of bone tumors. It can occur at any age but they are more common in patients younger than 20 years, approximately 10% are located in the head and neck region. Clinical features includes localized pain, fast growing swelling and also in some cases inferior alveolar nerve paresthesia. The recurrence rate is approximately 30% and the prognosis is favorable. The literature describes several protocols such as curettage, block resection with reconstruction, and therapeutic embolization for the treatment of ABCs. We present three cases of large mandibular ABC, analyzing the selection of the treatment determined by the size of the lesion and its biological behavior.
