Comparative Performance of Lateral Wall and Perimodiolar Cochlear Implant Arrays.

OBJECTIVE: The physical shape of cochlear implant (CI) arrays may impact hearing outcomes. The goal of this study was to compare post-operative speech and melody perception between patients with lateral wall (LW) and perimodiolar (PM) electrode arrays across a range of lengths and manufacturers. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary Care Hospital. PATIENTS: 119 adult patients with post-lingual hearing loss who underwent cochlear implantation. MAIN OUTCOME MEASURES: A total of seven different electrodes were evaluated including 5 different LW electrodes (CI422 [Cochlear American], 1J [Advanced Bionics], Medium [Med El], Standard [Med El], Flex28 [Med El]) and 2 PM electrodes (Contour [Cochlear American], MidScala [Advanced Bionics]). Speech perception outcomes (n = 119 patients) were measured by Consonant-Nucleus-Consonant (CNC) scores collected 3, 6, 12 and 24 months after implantation. Melody perception outcomes (n = 35 CI patients and n = 6 normal hearing patients) were measured by Melodic Contour Identification (MCI). RESULTS: CNC scores increased over time after implantation across all array designs. PM designs exhibited higher CNC scores compared to LW electrodes, particularly 6-months after implantation. Pre-operative pure tone averages did not correlate with post-operative CNC scores. PM arrays outperformed LW electrodes in terms of MCI scores. CONCLUSIONS: The physical shape of cochlear implant electrode arrays may impact hearing performance. Compared to LW designs, PM arrays appear to offer superior speech perception during the first 6 months after implantation, with performance equalizing between groups by 24 months. Compared to LW designs, PM arrays also appear to afford superior melody perception.

Association of Patient Self-esteem With Perceived Outcome After Face-lift Surgery.

IMPORTANCE: It is well understood that optimal psychological health is imperative to success in aesthetic surgical procedures. Self-esteem is a very sensitive psychological factor that can influence patients' motivations for seeking surgery as well as their perceptions of outcomes. OBJECTIVE: To use the Rosenberg Self-Esteem Scale (RSES) to correlate the outcome of rhytidectomy as perceived by the patient to further understand the association of self-esteem and the results of aesthetic facial rejuvenation. DESIGN, SETTING, AND PARTICIPANTS: A prospective study was conducted of 59 consecutive patients undergoing rhytidectomy performed by a single surgeon at a private practice from July 1 to October 31, 2013. The RSES was used to establish preoperative baseline scores and scores at a 6-month postoperative follow-up. A paired t test was used to compare statistical data before and after surgery. Change in self-esteem and the patient's evaluation of the surgical outcome was assessed. Analysis was conducted from July 1 to December 1, 2014. MAIN OUTCOMES AND MEASURES: Patients' change in self-esteem level after rhytidectomy, as assessed by the RSES. RESULTS: Of the 59 patients, 50 completed a 6-month postoperative questionnaire; mean age was 58 years (range, 37-73 years); 48 were women; and 44 were nonsmokers. The mean difference between baseline and 6-month scores showed an increase of 0.3 (baseline, 24.3; 6-month follow-up, 24.6), which was not statistically significant (P = .69). Subdivision of patients into groups by self-esteem level showed a statistically significant improvement in self-esteem after surgery in the group with low self-esteem, with a mean difference in the RSES score of 3.7 (P = .01), whereas the group with high self-esteem showed a decrease in the RSES score of -3.1 (P = .03) and the group with average self-esteem showed a nonsignificant increase of 0.5 in the RSES score (P = .59). The perceived change in youthful appearance (mean, 8.9 years) did not correlate with self-esteem changes. CONCLUSIONS AND REVELANCE: Patient's self-esteem before surgery may partially determine the quality-of-life outcome after surgery. Patients with low preoperative self-esteem saw an increase in self-esteem after surgery, those with average preoperative self-esteem experienced no change, and those with high preoperative self-esteem experienced a decrease in self-esteem after surgery. In our study, self-esteem measurements did not correlate directly with the positive effect of the surgical outcome, as patients showed no mean change in self-esteem, but patients thought that they appeared a mean of 8.9 years younger after their face-lift surgery. These findings underscore the complex nature of the human psyche as it relates to aesthetic surgery and demonstrates that patients exhibit a wide spectrum of psychological reactions after face-lift surgery.
