Children's Speech

Purpose The purpose of the study was to (a) compare the speech sound production abilities of 2-year-old children who are hard of hearing (HH) to children with normal hearing (NH), (b) identify sources of risk for individual children who are HH, and (c) determine whether speech sound production skills at age 2 were predictive of speech sound production skills at age 3. Method Seventy children with bilateral, mild-to-severe hearing loss who use hearing aids and 37 age- and socioeconomic status–matched children with NH participated. Children's speech sound production abilities were assessed at 2 and 3 years of age. Results At age 2, the HH group demonstrated vowel production abilities on par with their NH peers but weaker consonant production abilities. Within the HH group, better outcomes were associated with hearing aid fittings by 6 months of age, hearing loss of less than 45 dB HL, stronger vocabulary scores, and being female. Positive relationships existed between children's speech sound production abilities at 2 and 3 years of age. Conclusion Assessment of early speech sound production abilities in combination with demographic, audiologic, and linguistic variables may be useful in identifying HH children who are at risk for delays in speech sound production.

AbstractSubstantial loss of cochlear function is required to elevate pure-tone thresholds to the severe hearing loss range; yet, individuals with severe or profound hearing loss continue to rely on hearing for communication. Despite the impairment, sufficient information is encoded at the periphery to make acoustic hearing a viable option. However, the probability of significant cochlear and/or neural damage associated with the loss has consequences for sound perception and speech recognition. These consequences include degraded frequency selectivity, which can be assessed with tests including psychoacoustic tuning curves and broadband rippled stimuli. Because speech recognition depends on the ability to resolve frequency detail, a listener with severe hearing loss is likely to have impaired communication in both quiet and noisy environments. However, the extent of the impairment varies widely among individuals. A better understanding of the fundamental abilities of listeners with severe and profound hearing loss and the consequences of those abilities for communication can support directed treatment options in this population.

The World

During the last several decades, cochlear implant has been fully recognized in treatment of severe hearing loss. Development of modern technology enabled inconceivable possibilities of technical qualities of the device as well as development of usable coding strategies, which led to extraordinary results in patient rehabilitation. Although cochlear implantation has become one of the routine operative procedures throughout the world nowadays, it gives rise to certain complications. These complications, though rare, can sometimes be very serious, even with fatal outcome. If cochlear implantation is performed by experienced and well-educated team of experts, the possibility of complications is minimal and is certainly not the argument against cochlear implantation as a method of treatment of severe hearing impairments.

Indian Scenario

Introduction: Otosclerosis usually manifests as a progressive conductive or mixed hearing loss occurring clinically to varying degrees in 0.5% - 1% of the general population. Stapedectomy /stapedotomy is the current treatment of choice for conductive component of Otosclerosis. Materials and Methods: Sixty patients attending the department of ENT of a Medical College Hospital in Bangalore between October 2012 and October 2017 were included in the study.  Results: The incidence of otosclerosis is highest in the 3rd and 4th decade. Bilateral symptoms were present in 25% and 75% had unilateral symptoms, right side being more common in our study. Tinnitus and vertigo with deafness are seen in 60% and 25 % of the patients respectively.  Ninety percent of the patients presented with moderate to moderately severe hearing loss. Twenty four (40%) out of 60 audiograms studied showed Carhart's notch. Postoperativeclosure of a-b gap to within 10dB could be achieved in 65% cases. The p value calculated comparing pre and post op results is <0.0001 and significant. Vertigo was found to be most common post-operative complication (35%) followed by sensorineural hearing loss (6.6%). Other complications observed during the study include -  tympanic membrane tears, foot plate extrusion, lax long process of incus, perilymph leak. Conclusion: From the assessment of the postoperative hearing gain and postoperative complications, it can be concluded that small fenestra stapedotomy gives satisfactory post-operative outcome and may be appropriatein the Indian scenario.
