Abstract
Objective:To evaluate the therapeutic effects in terms of disease clearance and hearing improvement of canal wall up mastoidectomy in combination with Type I tympanoplasty in otitis media.Methods:A total of 78 patients (81 ears) with otitis media were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty. The postoperative tympanic membrane morphology, average of pure-tone hearing thresholds and average air-bone gap were used as the indices for evaluating therapeutic effects.Results:The patients were followed up for two years in average. All the tympanic membranes recovered, with the ear canals being dry. There were five cases (5 ears) of tympanic membrane retraction and one case of otitis media recurrence. Hearing was effectively recovered by 76.54% (62/81) after surgery.Conclusion:Combining canal wall up mastoidectomy with Type I tympanoplasty can treat otitis media safely and effectively due to high postoperative dry ear canal rate, satisfactory reconstruction of hearing and maintenance of ear morphology.

Mastoidectomy preserving the bony external auditory canal and tympanoplasty are referred to as closed technique or combined approach tympanoplasty that was first proposed by Sheehy and Janson,[1,2] aiming to improve the classical mastoidectomy
After rational selection of indications, 78 patients (81 ears) with otitis media were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty
A total of 78 patients (81 ears) with otitis media who were enrolled in our hospital from March 2009 to January 2012 were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty
Summary
Mastoidectomy preserving the bony external auditory canal and tympanoplasty are referred to as closed technique or combined approach tympanoplasty that was first proposed by Sheehy and Janson,[1,2] aiming to improve the classical mastoidectomy. The aim of this combined therapy is to eradicate infectious foci while retaining the bony external auditory canal. Hearing can be well maintained even patients take part in water sports or wearing hearing aid devices. This method better meets the pathophysiological requirements. Some otologists prefer open surgery to this protocol owing to high requirements of surgical technique and apparatus as well as inappropriate selection of indications that may lead to high recurrence rate.[3,4]
