ABSTRACT New procedure of vowel acoustic space (VAS) (of vowel acoustic triangles) transformation for the purpose of characterization of vowel production in individuals with long-term hearing loss (HL) was developed. OBJECTIVE: To characterize VAS of adult Russian speakers with long-term HL using newly developed acoustic indicators. MATERIAL AND METHODS: Recordings of sustained Russian cardinal vowels /a/, /i/, /u/ of 10 women and 10 men with long-term HL were acoustically analyzed. For each participant, two first formants of each vowel were measured and log-transformed (logF1, logF2). VAS was transformed into right triangles, their /u/ corners were moved to the origin, and their legs were aligned with axes. VAS was almost symmetrical, equal and have a maximum size in the control group consisted of subjects without hearing impai rment while these of long-term HL group VAS size tended to have reduced and VAS stretched along one axis. RESULTS: Our study showed that a new VAS normalization approach can distinguish at least three groups of people with long-term HL. CONCLUSION: There are those with vowel triangles stretched along logF1-axis, with vowel triangles stretched along logF2-axis, and with symmetrical vowel triangles. Causes of the VAS differences require further investigation. PMID:34783468 | DOI:10.17116/otorino20218605117 View on the web Inoreader. Take back control of your news feed.

Age features of the lower nasal passage according to endoscopy in children

xlomafota13 shared this article with you from Inoreader Age features of the lower nasal passage according to endoscopy in children Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(5):70-74. doi: 10.17116/otorino20218605170. ABSTRACT OBJECTIVE: To study the anatomical features of the lower nasal passage in children in the age aspect by analyzing the results of endoscopic examination of the nasal cavity. MATERIAL AND METHODS: The study included 377 children who did not have otorhinolaryngological and ophthalmological pathologies, as well as congenital anomalies in the architectonics of the nose. The distribution into 4 groups, depending on age, was carried out according to the main provisions of the classification of childhood periods by N.P. Gundobin: the first group - children under 1 year old - 80 (21.2%), the second group - from 1 year to 3 years inclusive - 97 (25.7%), the third group - from 4 to 6 years inclusive - 96 (25.5%), the fourth group (control) - from 7 years and older - 104 (27.6%). All patients underwent endoscopic examination of the nasal cavity using rigid en doscopes with a viewing angle of 0 and 30 degrees, 2.7 mm in diameter, and a fibroscope with an inspection angle of 0 degrees, 2.5 mm in diameter. RESULTS: The data on the features of the development of the lower nasal passage in children were obtained. Changes in such anatomical parameters as the diameter of the lower nasal passage, the location of the distal opening of the nasolacrimal canal and the lower turbinate itself in the nasal cavity are presented. Highlighted the peak age periods of the development of the lower nasal passage in children: the first 6 months, 3-4 years and 7-8 years of a child's life. It was revealed that in children under 6 months of age, the middle turbinates are closely adjacent to the lower ones, which, as a rule, are large, tightly pressed to the bottom of the nasal cavity, and therefore the lower nasal passages are extremely weakly expressed. With growing up, their diameter grows from less than 2.0 mm to an average value of 2.90±0.03 mm, while after 7 years, fully formed volumetric lower nasal passages are already noted. In newborns and children of the first year of life, the mouth of the nasolacrimal duct is as close as possible to the bottom of the nasal cavity, and during growing up it gradually shifts upward (finally settling in the area of the fornix of the lower nasal passage or in the area of transition of the fornix to the lateral wall of the lower nasal passage) and posterior to the anterior the end of the inferior turbinate (up to 4 years old is at a distance of less than 1.0 cm, from 4 to 6 years old - 1.0 cm, from 7 years old - 1.14±0.01 cm). CONCLUSIONS: The data obtained as a result of the study are necessary for an otorhinolaryngologist and an ophthalmologist for a full understanding of the processes of development and course, as well as methods of treating various combined rhinological and dacryological pathologies in children.

Hearing function in children after new coronavirus infection (COVID-19)

xlomafota13 shared this article with you from Inoreader Hearing function in children after new coronavirus infection (COVID-19) Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(5):28-34. doi: 10.17116/otorino20218605128. ABSTRACT The information about hearing status of patients who have had a COVID-19 is scattered. There are no studies among children population. OBJECTIVE: To evaluate hearing function in children after coronavirus infection. MATERIAL AND METHODS: 87 children aged from 5 months to 17 years who have had a new coronavirus infection were examined in three cities of Russia (St. Petersburg, Novosibirsk and Surgut). Audiologic examination depended on the age and included: otoscopy, TEOAE and DPOAE, ABR, impedansometry, pure tone audiometry, speech audiometry in quiet and noise. Fisher, LittlEARS and PEACH questionnaires were used as well. An evaluation of central auditory processing was performed in case of indications. RESULTS: In 80 children (92%) otoscopy didn't revealed any problems. All children had type A tympanogram. Acoustic reflex was registe red in 49 children (56%), wasn't registered on 1-2 frequencies in 27 (31%) children, was registered on only 1 frequency or wasn't registered at all in 11 (13%) children. OAE was present in 83 (95%) children. Audiometric thresholds in all children were within a normal range. Speech intelligibility in quiet and noise in most cases was normal. 7 children with poor speech intelligibility or low Fisher questionnaire results got an extended examination. Binaural fusion speech test, dichotic test, RuMatrix test, gap detection test data showed no signs of central auditory processing disorders. CONCLUSION: There are no cases of hearing loss or central auditory processing disorders were found in children after new coronavirus infection. Due to variety of symptoms and long-term consequences of COVID-19 further hearing examination is required in this group of patients.

A case of obliteration of a round window in otosclerosis

xlomafota13 shared this article with you from Inoreader A case of obliteration of a round window in otosclerosis Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(5):75-81. doi: 10.17116/otorino20218605175. ABSTRACT The article presents a brief review of the literature on the anatomy and physiology of the round window (RW) niche, the causes of occlusion, the diagnosis of this pathology, the features of auditory disorders and tactics when it is detected in patients with otosclerosis (OS). A clinical case of diagnosis and effective surgical treatment for obliteration of RW in a patient with advanced OS, which occurred in 2019 in 0.7% of cases, is described. Removal of RW niche obliteration was carried out with a curette and microcresis by smoothing the canopy over RW until partial visualization of the secondary membrane. It was this stage of the operation that made it possible to restore the normal hydrodynamics of the inner ear fluids and contributed to a functional result. Thus, the diagnosis of RW obliteration in patients with OS is difficult, but possible when us ing computed tomography of the temporal bones and assessing the mobility of the RW membrane or analyzing changes in hearing at the end of the operation, if it is performed under local anesthesia. The simultaneous performance of stapedoplasty and the removal of bone obliteration of RW makes it possible to safely achieve functional rehabilitation in patients with OS.

The significance of microanatomy of the round window in terms of cochlear implantation

xlomafota13 shared this article with you from Inoreader The significance of microanatomy of the round window in terms of cochlear implantation Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(5):42-47. doi: 10.17116/otorino20218605142. ABSTRACT Sensoneural hearing loss is a polyetiological disease, which is often a secondary reflection of systemic pathology and is associated with damage of the cochlea and auditory nerve receptors. An important point in the surgical stage of cochlear implantation is the introduction of an implant active electrode into the cochleostomy spiral channel through the cochleostoma or round window. However, the issue of intra-cochlear structures surgical trauma in such surgical intervention seems to be very important, as it may reduce the success of subsequent rehabilitation. Therefore, the study of the anatomy of the round window and adjuscent areas was the objective of this work. PMID:34783472 | DOI:10.17116/otorino20218605142 View on the web Inoreader.
