Abstract:

Objective    To explore the approaches to repair large tympanic perforation complicated with narrowed external auditory canal. Methods    Over-under myringoplasty was performed in sixty patients (62 ears) who suffered  from large tympanic perforation and narrowed external auditory canal. Half  to one year follow-ups were carried out to observe the changes of hearing ability and healing rate of the perforations. Results     Successful healing was achieved in 58 ears with the healing rate at 93.5%. 53 ears(85.5%) demonstrated improved hearing ability. No one-sdie healing of the eardrum or cholesteatoma of skin graft occurred. Conclusion    Over-under myringoplasty is a satisfactory method to treat patients with large eardrum perforation and narrowed external auditory canal. It provides good exposure to ease eardrum transplantation. Moreover, it is helpful to place the graft stably and prevent possible adhesion between the eardrum and promontory.
