Objectives: To determine if cochlear duct length and cochlear basal diameter, measured using routinely available radiology software, affect hearing outcomes after cochlear implantation with two different length electrodes.

Methods: 55 patients who received a Med-El Flex electrode were retrospectively reviewed. 34 patients received the Flex 31 electrode (31mm) and 21 patients received the Flex 28 electrode (28mm).

Article Synopsis
  • A study examined if preassessment before colonoscopy enhances bowel preparation quality and helps protect renal function in chronic kidney disease (CKD) patients.
  • Conducted over 12 months, the study included 1,704 patients, analyzing the impact of preassessment across three risk groups defined by comorbidities.
  • Results showed preassessed patients had significantly better bowel prep, with a 52% increase in quality for higher-risk patients, and a notable difference in kidney function change between preassessed and non-preassessed groups.

Background: Reduced nasal nitric oxide (nNO) has been shown in patients with chronic rhinosinusitis (CRS) but its clinical significance remains uncertain. The objective of this study was to measure nNO changes in patients undergoing endoscopic sinus surgery (ESS) for CRS and to explore its relationship to clinical measures of sinus mucosal health postoperatively.

Methods: This was a prospective study of CRS patients undergoing ESS.

Objectives/hypothesis: To investigate whether a contralateral routing of signal (CROS) microphone combined with a unilateral cochlear implant (CI) results in hearing improvement after a prolonged trial period.

Study Design: A prospective experimental trial was undertaken on a group of 10 postlingually deafened adults who are experienced CI users.

Methods: Participants completed audiometric testing and validated questionnaires with their unilateral CI alone, followed by addition of a CROS microphone (CI-CROS).

Introduction. Previous work has shown a strong association between alterations in cochlear vasculature, aging, and the development of presbycusis. The important role of vascular endothelial growth factor (VEGF) and its receptors Flt-1 and Flk-1 in angiogenesis suggests a potential role for involvement in this process.

Background: The microvascular anastomosis remains a technically sensitive and critical determinant of success in free tissue transfer. The microvascular anastomotic coupling device is an elegant, friction-fit ring pin device that is becoming more widely used.

Objective: To systematically review the literature to examine the utility of the microvascular coupler in free tissue transfer.
