Long-term cognition and speech recognition outcomes after cochlear implantation in the elderly.

OBJECTIVE: The purpose of this study is to investigate how cognition, as measured using the Self-Administered Gerocognitive Examination Test (SAGE), and age affect speech recognition scores in older adults (age > 65) at one year and two years after cochlear implantation. STUDY DESIGN: This is a prospective study. SETTING: This study was conducted at a single institution. METHODS: Unilateral cochlear implantation was performed by two surgeons on adult patients (>65 years) with postlingual bilateral sensorineural hearing loss. There were 230 patients who underwent cochlear implantation from January 2016 to June 2023. Fifty-five of these patients completed the SAGE questionnaire before implantation, one year after implantation, and 2 years after implantation. Paired t-test analysis was used to evaluate pre- and post-operative speech recognition scores (CNC, AzBio in Quiet). RESULTS: Patients who had normal preoperative cognition on SAGE showed greater improvement in postoperative speech recognition tests at 1 year and 2 years after implantation compared with patients who showed preoperative cognitive impairment. There were no significant differences in postoperative speech outcome between age group 1 (between 65 and 80 years old) and age group 2 (over 80 years old) cochlear implant recipients. There were no changes in cognitive SAGE scores after 2 years implantation. CONCLUSION: Cognitive function, as measured by SAGE, is a more reliable predictor than age in determining speech recognition improvement after cochlear implantation. Cochlear implantation did not improve postoperative cognition.

Clinical performance, audiological outcomes, and quality of life of the Cochlear Osia ® system.

OBJECTIVE: The Cochlear Osseointegrated Steady-State Implant Bone Anchored Hearing Device (Osia) is a surgically implanted titanium apparatus that utilizes a piezoelectric actuator under the skin to address conductive and mixed hearing loss as well as single-sided deafness. The purpose of this study is to examine the clinical, audiologic, and quality-of-life outcomes in patients who underwent Osia implantation. METHODS: This is a retrospective study analyzing 30 adult patients (age 27-86) with conductive healing loss (CHL), mixed hearing loss (MHL), or single-sided deafness (SSD) who were implanted with the Osia device from January 2020 to April 2023 at a single institution by the senior author. Preoperative speech score testing (CNC, AzBio in quiet, AzBio in noise) were performed in all subjects while unaided, wearing conventional air conduction hearing aids, and wearing a softband BAHA. These preoperative speech scores were then compared to post-implantation speech scores using paired t-test analysis to assess for degree of speech improvement. In order to analyze quality of life after Osia implantation, each patient filled out the Glasgow Benefit Inventory (GBI) survey. The GBI is a series of 18 questions answered using a five-point Likert scale that addresses the changes in general health status, physical health status, psychosocial health status, and social support after a medical intervention. RESULTS: CHL, MHL, and SSD patients had significant improvement in hearing and speech recognition scores after Osia implantation compared to preoperative unaided hearing: CNC (14 % vs 80 %, p < 0.0001), AzBio in Quiet (26 % vs 94 %, p < 0.0001), and AzBio in Noise (36 % vs 87 %, p = 0.0001). Preoperative speech scores using the softband BAHA were accurate predictors of post-implantation speech scores and can serve to determine surgical candidacy for the Osia. Post-implantation Glasgow Benefit Inventory patient surveys demonstrated significant improvement in quality of life with patients scoring an average increase of +54.1 points in heath satisfaction. CONCLUSION: Adult patients with CHL, MHL, and SSD can receive significant improvement in speech recognition scores after implantation with the Osia device. This translates to improved quality of life, which was confirmed on the post-implantation Glasgow Benefit Inventory patient surveys.

Atypical Meningioma of the Sinonasal Tract.

This case report describes a patient with intellectual disability who presented with a neglected midline nasal mass eroding the anterior skull base, which was found to be a Grade II meningioma likely of the olfactory bulb. Points of interest include differential diagnosis of this atypical mass of the sinonasal tract, as well as decision-making in balancing appropriate management and quality of life in a patient with developmental delay who could not make decisions for herself. Literature review regarding the role of adjuvant radiation based on final diagnosis and extent of disease suggests that radiation can improve locoregional control and overall survival with atypical meningioma. Lack of clear information in the literature on these rare conditions can lead to poor understanding on the part of the treatment team and the healthcare proxies who are making decisions, making goals of care discussions and medical decision-making challenging. This case report seeks to add to the available data on management of atypical meningiomas of the sinonasal tract and olfactory bulb.

Buccal Mucosa Graft Harvest in Children and Young Adults: Case Series and Harvest Technique.

Buccal mucosa is a great choice for urethroplasty for urethral stricture repair because of ease of harvesting, pliability of the graft, and minimal donor site morbidity. These procedures are performed at our institution as a combined case with Pediatric Otolaryngology and Urology. Harvesting buccal mucosal grafts in younger patients is more technically challenging due to limited oral cavity access and smaller area available for tissue harvest, but is able to be performed safely and with limited morbidity with the addition of parotid duct cannulation and use of retraction sutures to the graft harvest technique. This retrospective case series reports harvest technique, outcomes, and complications of children and young adult males undergoing buccal or lower lip mucosal graft harvesting to repair congenital urethral strictures. Outcome measures were perioperative bleeding, trismus, pain, numbness, parotid duct injury and lip deformity. Six patients underwent nine harvest procedures. Technique modifications included application of anterior graft margin stay sutures to help stabilize the graft mucosa and cannulation of the parotid duct with lacrimal probes to avoid duct injury and to maximize graft size. Overall, buccal mucosal graft harvesting is a well-tolerated procedure with minimal complications using proper harvest technique.

Fentanyl effects on breath generation in C57BL/6J and A/J mouse strains.

We examined the effect of fentanyl on chemoresponsiveness in mouse strains divergent in the expression of spontaneous and post-hypoxic pauses. Frequency and tidal volume were recorded with plethysmography in A/J and C57BL/6J (B6) male mice. Mice selected at random received an intraperitoneal (IP) injection of either saline, low dose fentanyl (LDF = 0.04 mg/kg), or high dose fentanyl (HDF = 0.4 mg/kg) under hypoxia (8% O2) or hyperoxia (100%O2). LDF produced a decrease in frequency during hypoxia in B6, but not A/J, mice. HDF significantly decreased frequency and tidal volume in both strains under hypoxia and hyperoxia (p<0.01); naloxone, an opioid antagonist, reversed this response. The acute administration of fentanyl at any dose did not promote apneas in strains of mice exhibiting regular or irregular respiratory patterns. However, higher doses depressed respiratory frequency in both strains. The B6 mice responded with a depressive response to hypoxia that did not recover with reoxygenation, but did recover with time or naloxone.
