          Abstract

          RESUMEN Los quistes nasolabiales son lesiones quísticas poco frecuentes, que se presentan como ocupación de la fosa canina, el ala nasal o el vestíbulo nasal. Usualmente son asintomáticas, pero pueden infectarse. El diagnóstico se realiza con el examen físico y exámenes imagenológicos, como la tomografía computarizada y/o resonancia magnética. El tratamiento consiste en la extirpación quirúrgica completa por abordaje sublabial, o por marsupialización endoscópica transnasal. Se describen dos casos, uno de ellos es una paciente de sexo femenino que presenta deformidad nasal producto del crecimiento progresivo de un quiste nasolabial unilateral, y otro de un paciente de sexo masculino que presenta una celulitis facial severa, con una tomografía computarizada que muestra quistes nasolabiales bilaterales. Los quistes nasolabiales deben ser considerados como parte del diagnóstico diferencial en otorrinolaringología en cuadros de deformidad nasal y aumento de volumen facial.

          ABSTRACT Nasolabial cysts are a rare developmental cyst, presenting as a fullness of canine fossa, nasal ala or vestibule of the nose. They are usually asymptomatic but may become infected. The diagnostic approach includes physical examination and imaging studies such as computed tomography and/or magnetic resonance imaging. Treatment is complete surgical excision by sublabial approach, or transnasal endoscopic marsupialization. Here we describe two cases, one female presenting as nasal deformity due to progressive growth of unilateral nasolabial cyst, and a healthy young male presenting severe facial cellulitis, with a computed tomography showing bilateral nasolabial cysts. Nasolabial cyst should be incorporated in the differential diagnosis of nose deformities and facial swelling in otorhinolaryngology.

          Pulp sensibility and vitality tests for diagnosing pulpal health in permanent teeth: a critical review.

          The aim of this review was to critically appraise the literature related to pulp vitality and sensibility testing in order to determine the diagnostic accuracy of pulp tests with reference to a gold standard or control group. Implications of the results for research and clinical practice are also explored. The MEDLINE (Ovid), MEDLINE (PubMed), Embase and Cochrane databases were searched for English-language clinical trials in humans in which in vivo studies were designed to evaluate or compare the accuracy of selected pulp sensibility and pulp vitality tests in determining the state of pulpal health in permanent teeth. Studies were included only if the results were compared to a control group or to a valid gold or reference standard. Eight studies were identified. Shortcomings in research design were found to influence the findings. The limited number of studies investigating pulp vitality tests was insufficient to answer the research question. It was concluded from this critical appraisal of the literature that laser Doppler flowmetry appeared to be the most accurate method for diagnosing the state of pulpal health and came closest to serving as a gold standard. Pulp vitality tests proved superior to pulp sensibility tests for early and accurate assessments of the pulpal health of traumatized teeth. When accurately used and interpreted, pulp sensibility tests provide valuable diagnostic information, particularly when an electric pulp test is used in combination with either CO2 snow or Endo-Ice.

            Nasolabial cyst: a report of eight cases and a review of the literature.

            Nasolabial cyst is a cystic ectodermal developmental swelling which occurs as a cyst on the lateral half of the floor of the nasal vestibule at the base of the alae of the nose. Although, it is a rare disease, this is a report of eight cases in a population of 500,000 in one year. Seven of the patients were female aged between 25-50 years. Seven cysts were left-sided and one was bilateral. The purpose of this paper is to present an additional example of patients with nasolabial cyst. It may be a more common disease than previously thought.

              A new transnasal approach to endoscopic marsupialization of the nasolabial cyst.

              Nasolabial cyst is a mucus-secreting, nonodontogenic cyst in the nasofacial area. It is usually situated behind the ala nasi, extending backward beneath the nasal floor into the inferior meatus and forward into the labio-gingival sulcus behind the upper lip. Patients with nasolabial cysts generally undergo surgical removal of the cyst via a transoral sublabial approach. This article reports a simple, less invasive surgical procedure for the treatment of nasolabial cysts. A transnasal endoscopic marsupialization method was designed to treat patients with nasolabial cysts. From 1996 through 1998, 16 consecutive patients underwent this new surgical procedure. With patients under local anesthesia, the roof of the cyst, which was firmly attached to the mucous membrane of the anterior nasal floor, was removed transnasally with a sickle knife and scissors. Under the guidance of a nasoendoscope, the opening of the cyst was widened with bite forceps. Meanwhile, the cut edges of the nasal mucosa and the epithelium lining of the cyst were adequately matched. The nose was then loosely packed. All but 1 of the 15 patients were successfully treated with this technique, and the whole surgical procedure was usually completed within 15 to 20 minutes. Postoperative endoscopic and radiological findings revealed that the cyst was replaced by an air-containing sinus with a persistent opening at the anterior or anterolateral nasal floor. There has been no evidence of mucus accumulation in the newly created sinus or recurrence of the cyst during a mean follow-up of 16 months. Transnasal endoscopic marsupialization is a simple and effective surgical procedure for treatment of nasolabial cysts.
