“…Nevertheless, in the case of severe congenital malformations such as aural atresia, surgical treatment is diYcult even in the most expert hands and is burdened by a high rate of major complications such as restenosis of the auditory canal, recurrent otitis externa, cholesteatoma, facial paralysis and cosmetic results that are often debatable. Furthermore, even after the most brilliant treatment some form of sound ampliWcation is often required [30]. In a series of patients with bilateral aural atresia treated with reconstructive surgery, Chang et al [2] found a long-term residual air-bone gap that averaged 30 dB HL, whereas Digoy and Cueva [31] reported a mean residual gap of 23 dB HL.…”

The aim of this work is to reexamine our experience with the treatment of conductive and mixed hearing loss using the Baha system. The system was implanted in 47 patients (16 adults and 31 children under the age of 14), bilaterally in two cases. The causes of hypoacusis were bilateral congenital aural atresia (31 patients), bilateral chronic otitis media or outcomes of middle-ear surgery (Gillett et al. in J laryngol Otol 120:537-542, 2006), and otosclerosis (Pazzaglia et al. in Acta Orthop Scand 54:574-579, 1983). The following parameters were assessed: mean preoperative air- and bone-conduction thresholds for the frequencies of 500, 1,000, 2,000 and 4,000 Hz; mean postoperative threshold with the Baha; hearing improvement calculated by subtracting the postoperative threshold with the Baha from the preoperative threshold for air conduction in the better ear; speech audiometry test; improvement in the quality of life, calculated using the Glasgow Benefit Inventory for the adult patients and the Glasgow Children's Benefit Inventory for paediatric patients; frequency and type of surgical complications. Follow-up ranged from 6 to 38 months. The audiological results were satisfactory, with air-bone gap closure in 85.1% of cases. In terms of quality of life, assessment using the Glasgow Benefit Inventory showed a clear-cut improvement in health for all the 45 patients that answered to the questionnaires in our study. Out of the 49 operations that were performed, complications were reported in 3 cases (6.1%): 2 cases of skin regrowth around the titanium screw and one in which the abutment was not osseointegrated. The data from this study show that the Baha system offers a high percentage of success, which can significantly improve the patient's quality of life, and a low rate of complications.

“…The testing performed thus far included basic pure-tone average measures [5,[7][8][9][10][11], speech recognition thresholds [5,9,12], and hearing in noise testing [8]. Though these studies report a clinical follow-up of up to five years, none have systematically controlled audiometric tests beyond six months after BAHA insertion.…”

“…Binaural summation consists of an improvement in auditory thresholds and perceived sound intensity when stimuli are presented to both ears simultaneously [6]. The head shadow effect refers to the reduced sound pressure level in one ear when the stimulus is presented contralaterally [7]. The squelch effect is the central nervous system's ability to selectively perceive meaningful sound stimuli in background noise by analyzing auditory input presented to both ears simultaneously [8].…”

“…Several authors have reported favorable hearing results after BAHA implantation using conventional audiometric testing [5][6][7][8][9][10][11][12]. We designed this prospective longitudinal study to evaluate the performance of pediatric patients equipped with BAHA on a series of systematic tonal and vocal evaluations, with specific emphasis on speech discrimination in different sound environments with a minimum follow-up of one year.…”

“…Specialists largely agree that surgical treatment of aural atresia is one of the most difficult operations to perform, because the functional results tend to vary and are hard to predict [3], and there is a high rate of complications [2,4,5].…”
