[Stapedectomy in congenital stapes fixation]

Area of Science:

• Otolaryngology
• Pediatric Otology
• Neurosurgery

Context:

• Congenital stapes fixation presents a surgical challenge in pediatric patients.
• Perilymph gushers during stapedectomy raise concerns, leading some surgeons to avoid the procedure.
• The pathophysiology of perilymph gushers in this context remains poorly understood.

Purpose:

• To evaluate the pre-operative presentation and post-operative hearing outcomes of pediatric patients undergoing stapedectomy for congenital stapes fixation.
• To investigate the incidence of perilymph gushers and significant sensorineural hearing loss in this specific patient cohort.
• To explore potential risk factors and pathophysiological mechanisms associated with perilymph gushers.

Summary:

• This study examined 10 children with congenital stapes fixation who underwent stapedectomy.
• No instances of perilymph gushers or significant sensorineural hearing loss were observed.
• The procedure successfully closed the air-bone gap in most patients, achieving hearing within 20 dB at speech frequencies.

Impact:

• This research suggests that stapedectomy for congenital stapes fixation in children can be performed safely with favorable hearing outcomes.
• Findings challenge the contraindication for surgical intervention in these cases.
• Understanding the association with male gender and potential internal auditory canal defects may refine surgical risk assessment.
