ABSTRACT
ABSTRACT Sialolithiasis is the formation of calcific concretions within duct of a salivary gland that affects the submandibular gland with greater prevalence. Stafne bone cavity is a rare mandibular defect of unknown etiology, which commonly presents glandular tissue inside. The aim of this work is to report the first clinical case of sialolithiasis of the submandibular gland with associated Stafne bone defect. Although most of Stafne bone cavity are associated with the salivary gland, there are no studies that prove the association between the two injuries, and further studies are needed to elucidate the relationship between the injuries.
RESUMO A sialolitíase é a formação de cálculos no interior do ducto de uma glândula salivar que acomete com maior prevalência a glândula submandibular. O defeito ósseo de Stafne é um defeito mandibular raro de etiologia desconhecida, que comumente apresenta tecido glandular no interior. O objetivo desse trabalho é relatar o primeiro caso clínico de sialolitíase da glândula submandibular com defeito ósseo de Stafne associado.Apesar da maioria dos desfeitos ósseos de Stafne estarem associado à glândula salivar, não há estudos que comprovem a associação entre as duas lesões, sendo necessários mais estudos para elucidar a relação entre as lesões.
ABSTRACT
Introduction:The dentigerous cyst, also called a follicular cyst is an odontogenic cyst that develops in association with crown of an impacted tooth, predominantly in mandibular third molars of young patients. The Odontoma is a ectomesenquimal tumor of unknown origin that are more considered developmental malformations (harmatomas) than benign neoplasms. Occasionally, the dentigerous cyst is associated with odontoma. Objective:The article aims to report a case of surgical treatment of dentigerous cyst associated with compound odontoma and unerupted tooth in anterior region of the mandible. Case report: A male patient, 17 years of age, without systemic changes, was sent to the Center for Dental Specialties of Horizonte, Ceará, Brazil, specialty of Oral and Maxillofacial Surgery, for diagnosis and treatment of oral lesions visualized after periapical radiographic examination to determine failed eruption of element 42. Observing the periapical radiograph it was possible to visualize radiopaque lesion suggestive of a compound odontoma and a cystic capsule in association with the element 42. A panoramic radiograph was requested and it was planned a surgical removal of odontoma with curettage of bone cavity and removing the cystic capsule and element 42. There were no significant postoperative complications, the suture removal was performed 7 days after surgery where it was possible to observe a good healing, no swelling and no paresthesia. Conclusion: The treatment of choice is surgical excision of the lesions with the tooth associated to the cyst, it should be performed with proper planning, avoiding injury to vital structures and should not be delayed in order to avoid possible occlusion sequelae.
