Quiste inflamatorio con tejido calcificado: presentación de un caso clínico / Inflammatory cyst with calcified tissue: presentation of a clinical case

Objetivo: Describir un caso de quiste odontogénico in- flamatorio cuya presentación imagenológica no es la habitual. Caso clínico: Acude a la clínica profesional de Pato- logía Oral de la Universidad Andrés Bello una paciente de género femenino de 13 años, sin antecedentes mórbidos, con un hallazgo radiográfico de lesión mixta ubicada entre los premolares inferiores derechos. Es derivada al posgrado de cirugía oral y maxilofacial para que le realicen una biopsia excisional de la lesión con una hipótesis diagnóstica de tumor odontogénico adenomatoide. Una vez realizado el estudio histopatológico, se define la lesión como quiste odontogénico inflamatorio, que por las características clínicas-radiográficas podría corresponder con un quiste residual de un diente tem- poral. Debido a la variabilidad en la presentación clínica e ima- genológica de las lesiones quísticas maxilofaciales, el estudio anatomopatológico es imprescindible para un correcto diag- nóstico y tratamiento (AU)

Aim: To present a case of inflammatory odontogenic cyst with unusual imaging presentation. Clinical case: A 13-year-old female patient, with no history of morbidity, with a radiographic finding of a mixed lesion located between the lower right premolars. The patient visited the professional Oral Pathology clinic of the Andrés Bello University and was referred to postgraduate oral and maxillofacial surgery for an excisional biopsy of the lesion, with a diagnostic hypothesis of adenomatoid odontogenic tu- mor. After the histopathological study, the lesion was defined as an inflammatory odontogenic cyst, which, based on clini- cal-radiographic characteristics, could be a residual cyst of a primary tooth. Due to the variability in the clinical and imaging pres- entation of maxillofacial cystic lesions, anatomopathological study is essential for correct diagnosis and treatment (AU)

Effects of dexmedetomidine for retrobulbar anesthesia in orbital ball implants after enucleation surgery.

Background: Dexmedetomidine (DEX) can prolong the duration of local anesthetics, but the use of retrobulbar DEX has not been fully elucidated. This study was designed to determine the effects of adding DEX to lidocaine‑bupivacaine for retrobulbar block in orbital ball implants after enucleation surgery. Materials and Methods: A total of 200 patients of both sexes aged 30–60 years of American Society of Anesthesiologists I and II, scheduled for orbital ball implants after enucleation surgery, were enrolled for the study. Patients were randomly assigned into one of the two groups: Control (n = 100) received lidocaine‑bupivacaine retrobulbar block, DEX (n = 100) received lidocaine‑bupivacaine plus 1 ug/kg DEX retrobulbar block. Hemodynamic data, duration of motor and sensory blocks, pain by visual analog scale, bispectral index (BIS), side effects, consumption of dezocine as a rescue analgesic, patient and surgeon satisfaction were recorded. Results: Duration of analgesia was prolonged in the DEX, compared with the control group ([258.35 ± 66.82 min] as [130.75 ± 29.52 min], [P < 0.05]). The median number of postoperative analgesic requests per patient during the first 24 h was decreased in the DEX group (P < 0.05). In the first 24 postoperative hours, DEX group consumed significantly less dezocine (P < 0.05). BIS values and mean arterial pressure remained lower in the DEX group, but within the safe range (P < 0.05). The side effect profile was similar between the two groups. Patients and surgeon satisfaction were higher in the DEX group (P < 0.05). Demographic characteristics were comparable in both groups (P > 0.05). Conclusion: Retrobulbar DEX reduces consumption of rescue analgesic, prolonged the duration of retrobulbar block, improved postoperative pain, provided better sedation effects, and increased patient and surgeon satisfaction after orbital ball implants after enucleation surgery.
