measured. Independent variables included age at CI implantation, preimplantation CNC score, time since CI activation,
hours of daily CI use, type of HL (prelingual, perilingual, or
postlingual), duration of HL, and degree of contralateral HL.
Results: Average daily device use was 11.04 hours per day
(range, 1.42-16.62 hours). Average speech perception score
was 48.62% (range, 0%-96%). Multiple regression analysis
revealed that hours of CI use per day (P < .001) and HL type
(P < .002) were significantly associated with speech perception
scores (adjusted r2 = 0.26, aim 1). Duration of CI use per day
was not significantly correlated with age at CI implantation,
preimplantation CNC score, time since CI activation, type of
HL, duration of HL, or degree of contralateral HL (aim 2).
Conclusions: Our results demonstrate that speech perception
outcomes are significantly but modestly correlated with duration of daily CI use and type of HL. No independent variables
were found to significantly impact hours of daily device use.

Otology/Neurotology

Development of Otology-Specific HealthRelated Quality-of-Life Instrument: Ear
Outcome Survey-16 (EOS-16)
Maija Liisa Hytönen, PhD, MD (Presenter); Juha Laakso;
Juha T. Silvola, MD, PhD; Jussi Jero; Saku Sinkkonen, MD, PhD
Objectives: A very important outcome measure in patient
care is its impact on patient's health-related quality of life
(HRQoL), which can be measured by HRQoL instruments.
Previous ear-specific HRQoL instruments have some limitations, such as being suitable only for 1 specific ear disease,
relevant aspects are missing, or items are unevenly weighed.
Also, the length of optimal recall period is unknown. For these
reasons, we developed a new survey to cover chronic ear diseases with balanced emphasis between categories of symptoms, hearing problems, need for care, and psychosocial
impact.
Methods: The items (questions and claims) were partly
based on existing surveys. Items were then reduced, modified,
and validated by thorough analysis. Patients were recruited by
nationwide participation of university otolaryngology centers.
Recruiting otologists evaluated the severity of the disease and
disability caused by it. We included adult patients with no
prior ear surgery. Patients also responded to a general HRQoL
instrument named 15D.
Results: A total of 186 patients were included. The relevance
and necessity of the original 24 questions were thoroughly
investigated, and 16 items were selected to the final EOS-16.
The most suitable recall period was 3 months. For validation,
Ear Outcome Survey-16 (EOS-16) scores were compared
with an additional patient group and healthy controls. EOS-16
correlated well with 15D as well as physician's evaluation of
the severity of the disease and disability caused by it.
Conclusions: EOS-16 is a new tool that was created taking
into account the existing literature on QoL surveys and the
versatility of patient populations. It is validated and can be
used for patients with different chronic ear diseases as a
HRQoL and patient-reported outcome measure instrument.

Diagnosis of Eustachian Tube Dysfunction
With Traditional Chinese Version of ETDQ7, Tympanogram, Dynamic Slow-motion
Video
Ching-Ching Chiu, MD (Presenter); Sheng-Chiao Lin;
Yu-Hsi Liu, MD
Objectives: Eustachian tube dysfunction (ETD) is associated
with many middle ear diseases, but a standard diagnostic tool
is still lacking. This study aims to establish the comorbidity
ratio and to evaluate the correlation of dynamic slow-motion
video endoscopy (DSVE), tympanogram, and the Chinese
version of the 7-Item Eustachian Tube Dysfunction
Questionnaire (ETDQ-7) in the patients with ETD.
Methods: We prospectively enrolled 57 patients diagnosed
with ETD and 51 healthy cases in a control group. The personal medical history, 2-way translated Chinese ETDQ-7, pure
tone average, tympanogram, and DSVE were collected and
performed. Categorical variables were compared using Pearson
chi-square test or Fisher exact test. The Pearson correlation
was calculated for DSVE, ETDQ-7, and tympanogram.
Results: Significantly higher rates of tinnitus, repeated otalgia, throat foreign-body sensation, facial or head dullness,
pain, and depression tendency were noted in the ETD group.
Comorbidity analysis revealed a significantly higher rate of
gastroesophageal reflux and smoking (P < .05) in the ETD
group but no statistical significance among allergic rhinitis or
chronic sinusitis compared with the control group. A significantly higher correlation between DSVE grading and scores of
ETDQ-7 but no positive findings among DSVE and tympanogram were noted.
Conclusions: Aural symptoms were common among ETD
patients; however, medical education and treatment for
depression as well as smoking should also be considered. The
ETDQ-7 score was significantly correlated with the severity
of obstruction over the nasopharyngeal office of the Eustachian
tube evaluated by DSVE through our research. Therefore,
other etiology or disease should be considered if the results
show inconsistency over ETDQ-7 and DSVE.
The Effect of Ear Involvement on the Clinical
Features and Prognosis on Antineutrophil
Cytoplasmic Antibody-Associated Vasculitis
Masahiro Okada, MD (Presenter); Yuuki Hosokawa;
Masato Teraoka; Hiroyuki Yamada, MD; Naohito Hato, MD
Objectives: The concept of otitis media with antineutrophil
cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV)
was recently proposed by the study group of the Japan
Otological Society. Early diagnosis of ANCA-associated vasculitis (AAV) localized to the ear is possible, yet little is
known about the effect of ear involvement on the clinical features and prognosis of AAV.
Methods: We retrospectively examined 36 patients diagnosed with OMAAV and 44 patients diagnosed with AAV
without ear involvement (non-OMAAV) at Ehime University
