High-Frequency Horizontal Semicircular Canal Function in Certain Menière’s Disease

Objectives: To characterize video head impulse testing (vHIT) in definitive Menière’s disease and to investigate the relationship between vHIT results and other audiovestibular function tests. Design: Fifty-four patients with certain Menière’s disease, that is, patients with clinically definite Menière’s disease and endolymphatic hydrops visualized by locally enhanced inner ear MR imaging, were recruited for this study. All patients underwent vHIT. The vestibular-ocular reflex gain at 60 ms and refixation saccades were the outcome parameters measured. Saccades were characterized by determining the saccade frequency, their mean latency, and their mean velocity. Results: Seven of 54 patients had bilateral normal vHITs. Clearly pathologically vHITs with decreased gain and refixation saccades were observed in further seven patients. The majority of patients exhibited vHITs with refixation saccades but normal gain. Saccades mostly occurred bilaterally. There was no correlation between vHIT gain or saccades and caloric irrigation, cervical vestibular evoked myogenic potential or audiometry for Menière’s ears. Furthermore, vHIT gain or saccades correlated neither with age nor with the duration of the disease. Conclusions: Pathological low vHIT gain values are rarely observed in patients with certain Menière’s disease, while refixation saccades occur very frequently. In the majority of patients, saccades occur bilaterally. In Menière’s disease, in contrast to vestibular neuritis, there is no compensatory decrease of saccade latency over time.

[Clinical features of the recurrence of idiopathic benign paroxysmal positional vertigo].

[Clinical features of the recurrence of idiopathic benign paroxysmal positional vertigo].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2018 Jan 20;32(2):118-121

Authors: Tian YS, Wang SZ, Liu Y, Wang D, Guo LR

Abstract
Objective:To investigate the clinical features of the recurrence of idiopathic benign paroxysmal positional vertigo(IBPPV)patients.Method:Patients with IBPPV were enrolled and were followed-up for 36 months after being well controlled.The data of the patients including age,gender,and co-morbidities(hypertension,diabetes,hyperlipidemia)were analyzed.Characteristics of the patients with recurrent BPPV were compared with those without recurrence.Result:Two hundred and one patients were enrolled and twenty-two(10.9%)patients presented recurrent IBPPV within 36 months.Among them,about 16% showed changes in the involved semicircular canals.50% recurrence occurred within 6 months after the first treatment.The recurrence rate of BPPV in 50-60 years old patients(50%)is higher than other patients(P=0.04).No significant difference in terms of gender or co-morbidities(hypertension,diabetes,hyperlipidemia)was observed between the two groups.Conclusion:The incidence of recurrence in idiopathic BPPV patients was 10.9%in the present study.The mean period of 50% recurrence after a symptom-free interval was about 6 months.Furthermore,different semicircular canals were involved in about 50% of patients during recurrence.BPPV recurrence was not correlated with age,gender or co-morbiditie.

Effects of Rhinoplasty on Labyrinthine Function.

Effects of Rhinoplasty on Labyrinthine Function.

Aesthet Surg J. 2018 May 11;:

Authors: Tekin AM, Soylu E, Turan Dizdar H, Yilmaz F, Bayazit YA

Abstract
Background: Rhinoplasty is a common surgical procedure that is requested and accepted by patients for cosmetic and functional reasons. Osteotomies are performed on nasal bone, maxillary crest, or vomer to fix the deviations of the nasal dorsum or septum. During the percussion of the osteotomes with the surgical mallet, the vibration energy diffuses to the cranium. Auditory and vestibular systems may be affected by these vibrations.
Objectives: To assess the effects of rhinoplasty, in which osteotomies were performed using a hammer, on the audiovestibular system.
Methods: Thirty adults who underwent rhinoplasty were included in the study group. Ten age and gender matched adults who had nasal surgery without surgical mallet or osteotome served as the control group. The patients in both groups were assessed using pure tone audiometry, tympanometry, distortion product otoacoustic emission testing, and vestibular evoked myogenic potential, as well as video head impulse tests (vHIT) before the operation and one week after the operation.
Results: On auditory assessment, there was no significant difference between the study and control groups regarding pure tone thresholds at frequencies of 250 Hz to 8 kHz (p>0.05) as well as otoacoustic emissions. The vestibular assessment performed by using vestibular evoked myogenic potential and vHIT did not reveal a statistically significant difference between the groups, before surgery, and after surgery (p>0.05).
Conclusions: Rhinoplasty appears to be a safe operation in terms of audiovestibular functions, and osteotomy, in which a hammer is usually used, does not have an impact on hearing and balance functions of the ear.

Are You There for Me? Joint Engagement and Emotional Availability in Parent-Child Interactions for Toddlers With Moderate Hearing Loss.

Are You There for Me? Joint Engagement and Emotional Availability in Parent-Child Interactions for Toddlers With Moderate Hearing Loss.

Ear Hear. 2018 May 11;:

Authors: Dirks E, Rieffe C

Abstract
OBJECTIVES: This study examined joint engagement and emotional availability of parent-child interactions for toddlers with moderate hearing loss (MHL) compared with toddlers with normal hearing (NH) and in relation to children's language abilities.
DESIGN: The participants in this study were 25 children with MHL (40 to 60 dB hearing loss) and 26 children with NH (mean age: 33.3 months). The children and their parents were filmed during a 10-minute free play session in their homes. The duration of joint engagement and success rate of initiations were coded next to the level of emotional availability reflected by the Emotional Availability Scales. Receptive and expressive language tests were administered to the children to examine their language ability.
RESULTS: Groups differed in joint engagement: children with MHL and their parents were less successful in establishing joint engagement and had briefer episodes of joint engagement than children with NH and their parents. No differences between groups were found for emotional availability measures. Both joint engagement and emotional availability measures were positively related to children's language ability.
CONCLUSIONS: Children with MHL and their parents are emotional available to each other. However, they have more difficulties in establishing joint engagement with each other and have briefer episodes of joint engagement compared with children with NH and their parents. The parent-child interactions of children with better language abilities are characterized with higher levels of emotional availability and longer episodes of joint engagement. The results imply that interactions of children with MHL and their parents are an important target for family-centered early intervention programs.

Burden of Hearing Loss on Communication Partners and Its Influence on Pursuit of Hearing Evaluation.

Ear Hear. 2017 Sep/Oct;38(5):e285-e291

Authors: Schulz KA, Modeste N, Lee JW, Roberts R, Saunders GH, Witsell DL

Abstract
OBJECTIVE: Describe how the burden on the communication partner (CP) from the patient's hearing loss, as perceived by both the patient and their CP, influences a patient's pursuit of hearing evaluation.
DESIGN: Cross-sectional design. Demographics, perception of patient's hearing loss, and associated burden on the CP were collected from both patient and CP via online questionnaires. Patients and their CPs from Duke University Medical Center Otolaryngology Clinic, 55 to 75 years of age, being seen for any reason, who indicated a CP has expressed concern about their hearing. Final sample was 245 matched pairs.
RESULTS: Based on completed questionnaires, on average, patients perceived their own hearing loss as more burdensome to the CP than the CP did. However, CPs of patients who believed themselves to have no hearing handicap scored the patient's hearing loss 54.3% higher than the patient. The patient's perspective about the amount of burden their hearing loss placed on the CP predicted patients seeking a hearing evaluation.
CONCLUSIONS: Recognition of early stage hearing loss and associated burden on CPs may be delayed in patients; CPs may help elucidate unrecognized concerns. Educational approaches that raise awareness of burden of hearing loss on CPs along with hearing loss indications could be a feasible, multidimensional strategy to promote help seeking behaviors.
