RESUMEN
Las ránulas son seudoquistes resultantes de la extravasación salival de las glándulas sublinguales. Diversos tratamientos han sido empleados, no obstante, la marsupializaión se ha demostrado es el método más utilizado. La modificación de la técnica convencional, haciendo un taponamiento con gasas medicadas, presenta bajos índices de recurrencia, mientras su aplicación cuidadosa. El objetivo de este trabajo fue evaluar los resultados obtenidos por el empleo de la técnica de marsupialización modificada en los casos de ránulas intraorales diagnosticadas en el Servicio de Estomatología de la Facultad de Odontología de la Universidade Federal do Ceará, entre marzo de 1999 a diciembre de 2010, y comparar estos datos con estudios previamente reportados en la literatura. Los datos, tras su colecta, fueron tabulados y analizados estadísticamente (SPSS, versión 17.0). Del total de 2.103 biopsias, 17 (0.8%) correspondieron a ránulas intraorales, con edad comprendida entre 10 y 34 años de edad (media de 22,9 años), siendo 82,4 mujeres y 17,6 hombres. El tamaño de las lesiones varió entre 0,3 y 4 cm, con un promedio de aproximadamente 1,8 cm. La técnica de marsupialización modificada empleada en 13 pacientes, presentó un solo caso de recidiva. Otras dos recurrencias fueron observadas cuando se utilizó la técnica de la extirpación de la lesión, usada en cuatro casos. Nuestros resultados mostraron que la marsupialización, con cambio de la técnica convencional, es un método conservador eficaz, aunque no estadísticamente significativo (p>0,05), debiendo ser elegido como primera opción en el tratamiento de ránulas intraorales, con tasas reducidas de recurrencia.
Ranulas are pseudocysts as a result of salivary extravasation of the sublingual glands. Various treatments have been used, however, has been shown marsupialization the most used. The modification of the conventional technique, carefully filling of the lesion with gauze soaked in nitrofurazone (Furacin ®), have low rates of recurrence. The aim of this study was to evaluate the results obtained using the technique of marsupialization modified in the treatment of intraoral ranulas diagnosed in the Service of Stomatology, Faculty of Dentistry at the Universidade Federal do Ceará, from March 1999 to December 2010, and compare these data with previously reported studies in the literature. The data, after collection, were tabulated and statistically analyzed (SPSS, version 17.0). Of the total of 2,103 biopsies, 17 (0.8%) were intraoral ranulas, aged between 10 and 34 years of age (mean 22.9 years), with 82.4 men and 17.6 women. The lesion size ranged from 0.3 to 4 cm, with an average of about 1.8 cm. Modified marsupialization technique used in 13 patients, presented a single case of recurrence. Two other recurrences were observed when using the technique of surgical excision, used in four cases. Our results showed that marsupialization, with change of the conventional technique is an effective conservative approach, although not statistically significant (p> 0.05), must be chosen as first choice in the treatment of intraoral ranulas, with reduced rates of recurrence.

PURPOSE: The objective of the study was to determine the relative frequency of odontogenic tumors (OTs) in the world population, directing an epidemiologic profile to these lesions. METHODS: Was conducted a search in epidemiologic studies involving OTs that are listed by PubMed and Ovid, EMBASE, and Cochrane Library, embracing the period from January 1960 to January 2010, to verify their incidence worldwide. We identified 195 articles, of which 19 articles were selected, considering the location, age, sex, histologic type, and World Health Organization classification. RESULTS: A total of 8544 OTs were found. The results showed a low frequency of malignant OTs in selected works. The most frequent tumor was ameloblastoma (39.6%), followed by odontoma (20.1%) and the newly included keratocystic OT (13.8%). CONCLUSIONS: These OTs are uncommon lesions in world population, and malignant OTs are very rare. The relative frequency of different kinds of OTs, the age, and the sex distribution show a marked geographic variation in incidence of those lesions. This was particularly notable in the ameloblastomas and odontoma, with the incidences being relatively well and weighted showing similar values to an average when compared with previous studies.
