RESUMO
PURPOSE: The aim of the study is to compare the operative time and postoperative complication outcomes for bone-anchored hearing aid (BAHA) implants using two different techniques: the C-shaped incision technique and the linear incision technique. METHODS: An analysis was carried out of 38 patients implanted with transcutaneous BAHAs during a 4-year period in a single otolaryngology department. RESULTS: The implantation was carried out under general anesthesia. Operative time was significant lower with the linear technique compared to the C-shaped technique (76.55 min, SD 16.75 vs. 93.17 min, SD 19.82; p = 0.007). There was no difference in postoperative complications between the two techniques. CONCLUSIONS: The use of linear incision for transcutaneous BAHA system implantation is associated with a reduced surgery time compared to the C-shaped technique, with no increase in postoperative complications.

OBJECTIVES: To compare nitric oxide (NO) serum levels in women with and without preeclampsia. METHODS: 106 women were classified into preeclampsia group (n = 40) and normotensive group (n = 66). NO content was measured in the serum. Clinical and laboratorial data were recorded for comparison. RESULTS: Preeclampsia presented a significant increase in nitrate and NOx levels compared to the control group. Uric acid, gestational age, systolic and diastolic blood pressure, and creatinine showed correlation with nitrates and NOx. CONCLUSION: Increase of NO was observed in preeclampsia women. Failure in the mechanism of action, dependent on cyclic GMP, may justify this finding.

HYPOTHESIS: Anomaly in the incudostapedial articulation (IS) may be responsible for persistent conductive hearing loss (HL) in Down's syndrome (DS) patients. Our goal was to perform a detailed histopathologic assessment of the role of the IS joint in the conductive HL. BACKGROUND: In addition to other disabilities, 38% to 78% of patients with Down's syndrome (Trisomy 21) have CHL, some of which are persistent despite maximum treatment. The cause of the persistent conductive HL remains unclear. METHODS: Retrospective analysis of temporal bone histopathology. Analyses of the midsection through the IS joint of 21 temporal bones (13 subjects) patients with DS and 31 temporal bones (18 subjects) from healthy subjects, performed by 2 blinded authors. The length of 7 different parameters of the width of the IS joint was measured and compared between the 2 groups. RESULTS: The IS joint of patients with DS was significantly wider than the normal control. As opposed to the control, it did not decrease because of age. CONCLUSION: The persistent conductive HL in some patients with DS might be caused by anomaly of the IS joint. In severe cases, corrective surgery should be considered.

As Infecções dos espaços profundos do pescoço, apesar da diminuição de sua prevalência, ainda são causa de elevada morbimortalidade na população. Essa patologia sempre foi um grande desafio tanto para o médico generalista quanto para o especialista, uma vez que o diagnóstico requer alta suspeita clínica e seu tratamento depende, além do manejo clínico e cirúrgico adequado, de boas condições de saúde e bem-estar do paciente. Este artigo tem como objetivo revisar a anatomia do pescoço e as infecções que acometem tais espaços, demonstrando a sintomatologia e seu tratamento específico

A ototoxicidade secundária ao uso de medicações é um acontecimento presente na prática médica diária e que deve ser evitada. Para tal, torna-se imprescindível o conhecimento das drogas potencialmente tóxicas à orelha interna, bem como a detecção precoce dos danos por elas provocados. Este artigo tem como objetivo destacar os fármacos de maior impacto no desenvolvimento de ototoxicidade, bem como sugerir medidas para sua prevenção
