When mold material is impacted in the ear canal and visualization of the middle ear is obscured, we advise against simple piecemeal removal. Such cases are best managed by an experienced otologist.

Tympanic membrane retraction pockets involving the pars tensa are not uncommon in clinical practice. Recurrent infections, ossicular erosion and cholesteatoma are the recognized sequelae. The management options include surveillance, medical treatment and surgery. The surgical procedures range from grommet insertion to extensive tympanoplasty procedures. We report our experience with simple excision and grommet insertion, performed in 31 ears in 26 patients as day cases. The follow-up ranged from 8 to 34 months with a mean of 16 months. The procedure was successful in 23 ears (success rate of 74%). Recurrence of retraction occurred in seven ears and in one ear there was a persistent perforation. Age, previous grommet insertion and severity of retraction did not have a statistically significant influence on the final outcome. We conclude that excision and grommet insertion is a simple, safe and efficient procedure for the management of tympanic membrane retraction pockets and can be considered in preference to extensive tympanoplasty.

ObjectiveThis study sought to compare disease recidivism rates between canal wall up mastoidectomy and a canal wall down with obliteration technique.MethodsPatients undergoing primary cholesteatoma surgery at our institution over a five-year period (2013–2017) using the aforementioned techniques were eligible for inclusion in the study. Rates of discharge and disease recidivism were analysed using chi-square statistics.ResultsA total of 104 ears (98 patients) were included. The mean follow-up period was 30 months (range, 12–52 months). A canal wall down with mastoid obliteration technique was performed in 55 cases and a canal wall up approach was performed in 49 cases. Disease recidivism rates were 7.3 per cent and 16.3 per cent in the canal wall down with mastoid obliteration and canal wall up groups respectively (p = 0.02), whilst discharge rates were similar (7.3 per cent and 10.2 per cent respectively).ConclusionOur direct comparative data suggest that canal wall down mastoidectomy with obliteration is superior to a canal wall up technique in primary cholesteatoma surgery, providing a lower recidivism rate combined with a low post-operative ear discharge rate.
