Characterization of consultations for odontogenic abscesses in a major Chilean hospital

OBJECTIVES: To characterize consultations for odontogenic abscesses at the dental and maxillofacial unit of the public emergency hospital in Santiago, Chile. METHODOLOGY: descriptive study, involving consecutive sampling of patients with diagnosis of odontogenic abscess, conducted between august and september 2016. descriptive statistics were performed to determine the frequency of diagnosis, affected tooth, sex and need for hospitalization. RESULTS: odontogenic abscesses accounted for 6.3 percent (n=414) of a total of 6,535 consultations. males represented 59 percent; 42 percent of odontogenic abscesses presented in molars and maxillary premolars. the vestibular space was the most frequently affected anatomical space (50 percent), associated in 53 percent of the cases to submucosal abscesses. ninety-eight per cent of patients were successfully treated on an outpatient basis, 2 percent required hospitalization, mainly associated to abscesses involving the deep submandibular space. CONCLUSION: odontogenic abscesses account for a low percentage of dental emergencies at the public emergency hospital in Santiago, Chile. most cases receive outpatient treatment.

Schwanoma Lingual en un Adolescente: Revisión de la Literatura a Propósito de un Caso / Schwannoma of the Tongue in an Adolescent: A Short Literature Review Apropos of a Case

El Schwanoma corresponde a un tumor neurogénico benigno, derivado de las células de la cresta neural, específicamente de las células de la vaina periférica nerviosa llamadas schwannocitos. El 25% de éstos, se presentan en cabeza y cuello, y sólo un 1% se presentan en la cavidad oral, principalmente en la lengua. Presentamos un caso de una niña de 13 años de edad con diagnóstico de Schwannoma de lengua. El propósito de este reporte es enfatizar que el schwanoma lingual es un diagnóstico diferencial a considerar, pese a su baja prevalencia, entre todas las otras lesiones linguales en niños o adolescentes.

A schwannoma is a benign neurogenic tumour originating from schwannocyte of the nerve sheat. A 25% of all schwannomas are seen in the tissues of the head and neck and only a 1% of them are located in oral cavity, especially in tongue. We report the case of a 13 year old girl diagnosed with a schwannoma of the tongue.
