Bone-anchored hearing aids in infants and children younger than 5 years Davids T; Gordon KA; Clutton D; Papsin BCArch Otolaryngol Head Neck Surg 2007[Jan]; 133 (1): 51-5OBJECTIVE: While bone-anchored hearing aids (BAHAs) are currently indicated for rehabilitation in children older than 5 years with bilateral maximal conductive hearing loss, our objective was to capitalize on potentially important stages of auditory and speech-language development by providing BAHAs to children younger than 5 years. DESIGN: A retrospective review of surgical data of children receiving BAHA implants over a 10-year period. SETTING: The Hospital for Sick Children, Toronto, Ontario. PATIENTS: Twenty children 5 years or younger (mean +/- SD age, 3.21 +/- 1.65 years) served as the study group, while 20 older children (mean +/- SD age, 7.63 +/- 1.55 years) served as the comparison group. INTERVENTIONS: All patients received BAHA implants. Children with cortical bone thickness less than 2.5 mm underwent a 2-stage procedure; children with cortical bone thickness greater than 4 mm underwent a single-stage procedure. MAIN OUTCOME MEASURES: Traumatic and skin revision complication rates and implantation interstage intervals were compared between groups. RESULTS: The mean +/- SD interstage interval was 7.72 +/- 3.81 months for the younger children, which was significantly longer than for the older children (4.41 +/- 2.51 months) (P<.003). Two traumatic fixture losses occurred in the younger children, while 4 occurred in the older children. Skin site revision was required in 3 younger children. All children are currently wearing their BAHAs. CONCLUSION: Two-stage BAHA implantation with a prolonged interval between stages yields surgical success in younger children comparable to that routinely observed in older children.|*Hearing Aids[MESH]|Child, Preschool[MESH]|Female[MESH]|Hearing Loss, Conductive/rehabilitation[MESH]|Humans[MESH]|Male[MESH]|Postoperative Complications[MESH]|Prosthesis Implantation[MESH]|Reoperation[MESH]|Retrospective Studies[MESH]|Treatment Outcome[MESH] |
