Facial Nerve Outcomes After Vestibular
Schwannoma Microsurgical Resection in
Neurofibromatosis Type 2
Catherine Sobieski (Presenter); Daniel E. Killeen, MD;
Samuel L. Barnett, MD; Jacob B. Hunter, MD; Brandon
Isaacson, MD; J. Walter Kutz, MD
Objectives: Neurofibromatosis type 2 (NF2) is a genetic disorder that presents with bilateral vestibular schwannomas
(VS). VS in NF2 usually present at an earlier age and with
greater tumor sizes than sporadic VS. The aim of this study is
to investigate facial nerve outcomes after microsurgical resection in NF2 compared with sporadic tumors.
Methods: This study is a single institutional retrospective
chart review at a tertiary referral center. All adult patients with
NF2 VS or sporadic VS who underwent surgical resection
from 2008 to 2018 with preoperative magnetic resonance
imaging and 10 months of postsurgical follow-up are included.
The primary outcome measure is postoperative facial nerve
outcome as assessed by the House-Brackmann (HB) facial
nerve score.
Results: A total of 175 sporadic VS and 15 NF2 VS met
inclusion criteria. The median diameter for NF2 VS was 33.5
mm (range, 8.7-46.1 mm) compared with 24.6 mm (range,
4.1-47.1 mm) for sporadic VS (P = .005). The median volume
for NF2 VS was 12.4 cm3 (range, 0.26-32.9 cm3) compared
with 3.17 cm3 (range, 0.01-30.6 cm3) for sporadic VS (P =
.003). The median follow-up was 24.3 months (range,
10-130.1 months). Median facial nerve function after 10
months for NF2 patients was HB 3 (range, 1-6) compared with
HB 1 (range, 1-6) for sporadic VS (P = .001). With multivariate logistic regression, NF2 tumors (odds ratio [OR] 10.78, P
= .002) and tumor volume ≥3 cm3 (OR 3.17, P = .048) were
significantly associated with HB ≥3 when controlling for age,
sex, translabyrinthine resection, extent of tumor resection,
prior surgery, and prior radiation.
Conclusions: Tumor volume >3 cm3 and NF2 tumors are
associated with poorer facial nerve outcomes at least
10 months following microsurgical resection.
Factors Associated With Quality of Life
After Cochlear Implantation in Older Adults
Alana N. Aylward, MD (Presenter); Morganne MurphyMeyers; Chelsea M. Allen, PhD; Geoffrey C. Casazz, MD;
Richard K. Gurgel, MD
Objectives: A study was conducted to determine hearingrelated quality-of-life outcomes for older cochlear implant
recipients and to evaluate what clinical factors are associated
with improved quality of life.
Methods: Adults older than 65 years receiving cochlear
implants at our institution between July 13, 2000, and April 3,
2019, were asked to complete the Nijmegen Cochlear Implant
Questionnaire (NCIQ) regarding hearing-related quality of
life. Chart review was undertaken to define clinical characteristics of these patients. Univariate and multivariate linear
regression models were developed for hearing-related quality
of life with independent variables sex, 11-factor modified
frailty index (mFI-11), duration of hearing loss, hearing aid
use, age at surgery, time since surgery, difference in hearing
scores, and processor type.
Results: A total of 380 surveys were distributed by mail, and
143 were returned. Twenty-eight patients (20%) had bilateral
implants, 115 (80%) had unilateral implants. Mean age at time
of survey was 80.7 years with mFI of 0.11. Mean duration of
hearing loss prior to implantation was 27.8 years, and 88% of
patients used hearing aids before cochlear implantation. Mean
NCIQ score was 57.9 out of 100. Mean improvement in pure
tone average with implantation was 52.6 dB on the left and
57 dB on the right. On univariate analysis, lower mFI score
(better health), longer duration of hearing loss, and improvement in pure tone average correlated with improved NCIQ
scores with P values of .003, .039, and .011, respectively. On
multivariate analysis, only improvement in pure tone average
remained significant with a P value of .012.
Conclusions: Hearing-related quality of life in older adults
receiving cochlear implants is correlated with improvement in
measured hearing outcomes.
Genetic Etiology of Deafness in a Large
Cohort of Cochlear Implant Recipients
Kristen L. Seligman, MD (Presenter); Aiden E. Shearer, MD, PhD;
Marlan R. Hansen, MD; Kathy Frees; Diana Kolbe; Camille
Dunn; Bruce J. Gantz, MD; Richard J. H. Smith, MD
Objectives: Deleterious genetic mutations in hearing loss
patients can not only determine the pattern and course of a
patient's hearing loss but may also predict performance after
cochlear implantation. The purpose of this study is to provide
a genetic epidemiological survey of pathogenic or likely
Otology/Neurotology
Results: Of 279 patients, 256 met the inclusion criteria
(mean age 47.7 years, 62.5% women). Operative approaches
consisted of translabyrinthine (n = 130), retrosigmoid (n =
64), and middle fossa (n = 62). Twelve (4.7%) had prior radiation and 5 (2.0%) underwent prior resection. Gross or neartotal resection was achieved in 237 (92.6%), and the FN was
anatomically preserved in all cases. A total of 227 (88.7%)
patients had good FN function immediately after surgery. Of
those with HB III-VI, 53.3% recovered to HB I-II within
6 months. Gross/near-total resection (odds ratio [OR] 1.97,
P = .014), good immediate FN grade (OR 3.38, P < .001), and
excellent EMG response defined as >100 µV response from
0.05 mA stimulus (OR 8.53, P < .001) were associated with
better long-term FN outcome. Excellent intraoperative EMG
was predictive of good FN outcome when tumor size and surgical approach were taken into account (OR 7.86, P < .001).
Conclusions: Surgical resection of VS can be accomplished
with minimal FN morbidity. More than half of patients with
facial palsy recover within 6 months. The presence of an
excellent EMG response may predict good FN outcome long
term, regardless of the operative approach.
