ABSTRACT
Los quistes de retención mucosa y los mucoceles son las lesiones máscomunes de los senos paranasales. Éstos comparten características muysimilares y su diferencia estará determinada por su etiología. A diferencia del quiste de retención mucosa, cuyo comportamiento es mucho más sutil, el mucocele causa fenómenos infl amatorios locales, y algunas veces,reabsorción ósea de las estructuras adyacentes. El tratamiento será laenucleación quirúrgica. En el caso clínico que presentamos a continuación,se evidencia una lesión quística que se expone a través del alvéolo no cicatrizal de extracción traumática realizada semanas atrás, además se presenta la técnica que utilizamos para el cierre de fístula oroantral.
Mucus retention cysts and mucoceles are the most common lesions of the paranasal sinuses. They share very similar characteristics and the difference between them depends on their etiology. Unlike mucous reten-tion cysts, whose behavior is much more subtle, mucoceles cause local infl ammatory phenomena and sometimes bone resorption of adjacent structures. The treatment called for is surgical enucleation. The clinical case presented deals with a cystic lesion protruding through the non-cicatricial alveolus following a traumatic extraction performed weeks earlier. We also present the technique used to close the oroantral fi stula.

Cysticercosis is a potentially fatal parasitic disease that rarely involves the oral region in humans. This study includes 21 lesions seen in 16 Latin American patients. There were 8 men and 8 women, with an age range from 6 to 67 years (mean 33.6 years). Most cases appeared as asymptomatic submucosal nodules that resembled mucous cysts or benign mesenchymal neoplasms. Most were found in the tongue (11 cases), followed by buccal mucosa and the lower lip (4 cases each) and upper lip (2 cases). These were well circumscribed, and ranged in size from 1 to 2.5 cm in diameter. Typical histologic features of viable cysticerci were observed in 15 cases, and the presence of colloid degeneration and granular mineralization were detected in only 1 case. In all cases, simple surgical excision was sufficient to ensure complete removal of the lesions without postoperative complications. It is important to carry out a detailed study in every case, in order to exclude the presence of the parasite in other sites.

OBJECTIVE: To study the effects of pilocarpine hydrochloride on whole salivary gland production in Mexican patients affected by hyposalivation secondary to radiotherapy of the head and neck region. STUDY DESIGN: With previous written informed consent, 20 patients affected by hyposalivation secondary to head and neck radiation therapy (>40 Gy) were evaluated through the whole saliva test (WST) before, during and after ten weeks of treatment with pilocarpine hydrochloride (5 mg t.i.d.). Hyposalivationrelated symptomatology was assessed before and at every week by means of a questionnaire with an ordinal scale ranging from 0-10. Salivary production values recorded at the end of the study and those obtained before treatment were compared by means of student's t test. A paired Wilcoxon test was used to compare the differences in the oral symptoms, such as oral dryness, soreness, ability for speaking and swallowing before and after treatment. RESULTS: Initial WST had a mean salivary production of 0.8 cm (s.d. 0.7), with a range from 0 to 2.9 cm). After ten weeks of treatment salivary production increased to a mean of 2.24 cm (s.d. 0.7), with a range from 1.2 to 4.0 cm. There was a salivary flow increase of 64.5% (p<0.001). In addition, there were significant improvements in oral dryness, mouth comfort, ability to speak and ability to swallow (p<0.01). Adverse effects were usually minimal and they did not cause withdraw from the study in any case. CONCLUSIONS: Administration of 5-mg pilocarpine hydrochloride tablets three times daily significantly improved salivary production and clinical symptomatology secondary to radiation-induced hyposalivation with minimal side-effects. In addition, this study showed that WST is a fast, technically simple and highly reliable method to study salivary production in prospective studies.
