Abstract

SummaryObjectivesTo describe the lateral graft type 1 tympanoplasty technique using AlloDerm® for tympanic membrane reconstruction in children and to compare its surgical and audiometric outcomes with the traditional underlay type 1 tympanoplasty.MethodsThe records of 34 consecutive children undergoing type 1 tympanoplasty between 2004 and 2005 were reviewed; 18 received lateral graft tympanoplasty with AlloDerm® and 16 received underlay tympanoplasty (8 AlloDerm® and 8 temporalis fascia). Pre- and post-surgical audiograms, speech reception threshold, closure rate and complication rate were evaluated using one-way and repeated measures ANOVAs.ResultsChildren who underwent lateral graft type 1 tympanoplasty pre-operatively had larger tympanic membrane perforations, worse pure tone averages, air bone gaps and speech reception thresholds as compared with children undergoing underlay type 1 tympanoplasty (P < 0.001). Pure tone averages and air bone gaps improved significantly with surgery in both lateral and underlay type 1 tympanoplasty groups (P < 0.05), with both groups achieving comparable postoperative audiometric outcomes (P > 0.01). The lateral graft group demonstrated a higher perforation closure rate (94%) as compared with both underlay groups (88%). Complication rates were virtually non-existent.ConclusionsDespite larger perforations and worse pre-operative audiometric scores, children who underwent lateral graft type 1 tympanoplasty achieved comparable postoperative audiometric results and perforation closure rates as compared with children who underwent underlay type 1 tympanoplasty. Results suggest that lateral graft type 1 tympanoplasty using AlloDerm® is effective for tympanic membrane reconstruction in children and should be used when temporalis fascia is not available or the extent of the perforation limits its use.
