Objective:
This study aimed to evaluate the surgical success of a modified inlay tympanoplasty technique, known as circumferential subannular tympanoplasty, for anterior and subtotal perforations.
Methods:
This prospective study was performed in a tertiary care teaching hospital between October 2013 and April 2016. A total of 58 adult patients of both sexes with anterior or subtotal perforations underwent circumferential subannular tympanoplasty under local anaesthesia. In this technique, after tympanomeatal flap elevation, the temporalis fascia graft is placed directly onto the annulus instead of being tucked underneath the tympanic membrane remnant. Outcome data were graft uptake and hearing improvement.
Results:
This technique had a surgical success rate of 97 per cent and led to significant hearing improvement.
Conclusion:
Circumferential subannular tympanoplasty has a definitive role in managing anterior and subtotal perforations.
