“…Although 30 mJ equates the recommended pulse energy by Szyfter et al ( 31 ) and Hausler et al ( 10 ), results of the perforation were unsatisfactory. In addition, the total energy in all three samples was beyond the recommended total energy of 400 mJ to avoid inner ear damage ( 31 , 32 ). Hence in this study, we cannot conclude that the risk of inner ear damage could be reduced by using 30 mJ pulses.…”

“…A pulse energy of 60 mJ has been described by Lippert et al ( 30 ) as the optimal energy for footplate perforation. Another set of experiments showed that a single Er:YAG laser shot should not exceed 35 mJ and the total energy should not exceed 400 mJ to avoid inner ear damage ( 31 , 32 ).…”

Objective:Using a contact-free laser technique for stapedotomy reduces the risk of mechanical damage of the stapes footplate. However, the risk of inner ear dysfunction due to thermal, acoustic, or direct damage has still not been solved. The objective of this study was to describe the first experiences in footplate perforation in cadaver tissue performed by the novel Picosecond-Infrared-Laser (PIRL), allowing a tissue preserving ablation.Patients and Intervention:Three human cadaver stapes were perforated using a fiber-coupled PIRL. The results were compared with footplate perforations performed with clinically applied Er:YAG laser. Therefore, two different laser energies for the Er:YAG laser (30 and 60 mJ) were used for footplate perforation of three human cadaver stapes each.Main Outcome Measure:Comparisons were made using histology and environmental scanning electron microscopy (ESEM) analysis.Results:The perforations performed by the PIRL (total energy: 640–1070 mJ) revealed a precise cutting edge with an intact trabecular bone structure and no considerable signs of coagulation. Using the Er:YAG-Laser with a pulse energy of 30 mJ (total energy: 450–600 mJ), a perforation only in the center of the ablation zone was possible, whereas with a pulse energy of 60 mJ (total energy: of 195–260 mJ) the whole ablation zone was perforated. For both energies, the cutting edge appeared irregular with trabecular structure of the bone only be conjecturable and signs of superficial carbonization.Conclusion:The microscopic results following stapes footplate perforation suggest a superiority of the PIRL in comparison to the Er:YAG laser regarding the precision and tissue preserving ablation.

“…The usefulness of both CO 2 and Er:YAG lasers in stapes surgery have been confirmed with a decrease in the hearing threshold [11] . The 3-year follow-up of patients who received laser treatment showed that the Er:YAG laser was the safest type of pulsation laser for use in ear surgery because no facial nerve paralysis or adverse effects were observed in the inner ear function [12] .…”

OBJECTIVE:This study aimed to observe differences in the efficacy of laser and surgical treatments of middle-ear conductive hearing loss (MECHL). MATERIALS and METHODS:A total of 276 ears of 267 patients with MECHL were divided into laser (n=172) and surgical (n=104) treatment groups according to the treatment method. Changes in the air-bone gap (ABG) after treatment and at the time of final follow-up were compared. An ABG value <20 dB was defined as effective and an ABG value <10 dB, significantly effective. The long-term treatment effects were also compared at the time of final follow-up. Additionally, postoperative adverse reactions were recorded for both the groups. RESULTS:The mean follow-up period was 76.77±43.62 months (range: 12-168 months). No significant difference in ABG was found between the two groups (21.31±11.64 dB vs. 19.14±9.79 dB, p>0.05). However, the laser treatment group showed slightly better results than the surgical treatment group at the final follow-up, although the difference between the groups was not found to be significant (11.69±9.98 dB vs. 12.62±10.94 dB, p>0.05). There was no difference in the long-term treatment effects between the two groups (effective: 87.21% vs. 88.46%, p>0.05; significantly effective: 55.81% vs. 56.73%, p>0.05). The incidence rates of postoperative adverse reactions were not significantly different. CONCLUSION:The treatment efficacy of laser and surgical treatments for MECHL are similar.

“…Такой большой процент неподтверждения тугоухости связан с большим количеством факторов риска, при наличии которых дети направляются на 2-й этап скрининга, что создает повышенную загруженность аудиологической службы и влечет лишние расходы по реализации программы. В связи с этим созрела необходимость пересмотра протокола программы в отношении отслеживания детей c факторами риска [26].…”

The problem of diagnostics of congenital hearing impairment has acquired special importance in the light of new possibilities for the early rehabilitation of the patients presenting with this condition. The implementation of the programs of universal audiological screening into the clinical practice of Russia and many other countries made it possible to significantly reducethe time necessary to confirm congenital impairment of hearing and begin the rehabilitative treatment. The present paper was designed to analyze the international experience with the implementation of the programs of universal audiological screening of the newborn infants as exemplified by such countries as Great Britain, USA, Germany, and Poland. The main indicators of the quality and the efficiency of such programs are considered taking into account the results of the epidemiological studies on the prevalence of congenital hearing impairment. A total of 1.8 mln newborn infants were examined in Russia during 2013. The first stage of screening involved 96.7% of the children, and only 2.9% of them remained uncovered by the examination. As many as 5,659 children were found to present with the congenital loss of hearing,with the prevalence of this condition being 3 per 1.000 newborn infants and the prevalence of deafness 0.6 per 1.000. The principal problem to be resolved for the organization of the management of these patients, both in Russia and other countries, remains the enhancement of the availability of comprehensive diagnostic examination and the timelyreferral of the patients to such examination (if appropriate based on the results of the screening). The successful solution of this problem requires personalized recording of the screening data with the use of the commonly accepted medical information systems.
