ABSTRACT
BACKGROUND:
Methods to effectively overcome re-stenosis or atresia following reconstruction of external auditory canal are explored.OBJECTIVE:
To explore the effect of NiTi shape memory alloy netlike bracket to prevent the restenosis or atresia of newly constructed external ear canal in external canal atresia surgery. DESIGN, TIME ANDSETTING:
Case analysis of aural atresia patients from Department of Otorhinolaryngology Head and Neck Surgery, Third Hospital of Sun Yat-sen University was performed from January 2001 to June 2003.PARTICIPANTS:
Eight cases of aural atresia were selected, including 5 patients with congenital aural atresia, and 3 with postnatal aural atresia. All cases had different degrees of conductive hearing loss.METHODS:
All cases underwent external canals reconstruction by using NiTi shape memory alloy netlike brackets. MAIN OUTCOMEMEASURES:
Diameter of newly constructed aural canal and pure tone auditory threshold.RESULTS:
All the eight ears had a smooth and wide external ear canal during follow up. No restenosis of canal or cicatricial contracture was found. Pure tone auditory threshold of 7 ears had improved postoperatively.CONCLUSION:
NiTi shape memory alloy netlike bracket has definite effect to prevent the restenosis or atresia of new constructed external ear canal.
