title: Reevaluation of bilateral same-day surgery for bilateral perforated chronic otitis media.
abstract: OBJECTIVE
  To evaluate the results of bilateral same-day surgery for bilateral perforated chronic otitis media in comparison with our previous report.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  Seventeen patients ranging in age from 5 to 70 years (mean, 52.5 yr), with bilateral perforated chronic otitis media.
  
  
  METHODS
  Two hundred cases of chronic otitis media were operated on at the Department of Otolaryngology, Hyogo College of Medicine from December 1998 to November 2002. Fifty-nine patients (29.5%) had bilateral disease and 17 patients (8.5%) underwent bilateral same-day surgery.
  
  
  RESULTS
  The postoperative air-bone gap was less than 10 dB on both sides in 5 of 17 (29%) and less than 20 dB in 15 of 17 (88%). The postoperative hearing level was less than 20 dB in both ears in 4 of 17 (24%), less than 30 dB in 7 of 17 (41%), and less than 40 dB in 10 of 17 (59%). The rate of closure of the ear drum was 20 of 22 (91%) in the simple underlay myringoplasty series and 9 of 12 (75%) in the conventional myringoplasty/tympanoplasty series. The rate of closure of the ear drum on both sides was successful in 4 of 5 (80%) that underwent simple underlay myringoplasty/simple underlay myringoplasty and 8 of 12 (67%) that underwent simple underlay myringoplasty/conventional myringoplasty/tympanoplasty, whereas that on at least one side was successful in 100%.
  
  
  CONCLUSIONS
  Bilateral same-day surgery for bilateral perforated chronic otitis media is possible if operative indications are considered. Furthermore, it will help patients save time and money.
