The mean weighted closure rate for pediatric tympanoplasty was 83.4%. Subgroup analysis found age not to be a significant factor affecting the closure rate. Tympanoplasties performed on larger perforations or in children with abnormal contralateral ear findings were more likely to fail. Surgery may be best delayed until contralateral otitis media with effusion has settled.

Balance disequilibrium is a significant contributor to falls in the elderly. The most common cause of balance dysfunction is loss of sensory cells from the vestibular sensory epithelia of the inner ear. However, inaccessibility of inner ear tissue in humans severely restricts possibilities for experimental manipulation to develop therapies to ameliorate this loss. We provide a structural and functional analysis of human vestibular sensory epithelia harvested at trans-labyrinthine surgery. We demonstrate the viability of the tissue and labeling with specific markers of hair cell function and of ion homeostasis in the epithelium. Samples obtained from the oldest patients revealed a significant loss of hair cells across the tissue surface, but we found immature hair bundles present in epithelia harvested from patients >60 years of age. These results suggest that the environment of the human vestibular sensory epithelium could be responsive to stimulation of developmental pathways to enhance hair cell regeneration, as has been demonstrated successfully in the vestibular organs of adult mice.

Diffusion-weighted MRI is both sensitive and specific for the detection of recurrent or residual cholesteatoma following ear surgery. Non-EPI techniques are superior to EPI techniques.

Surgeons should be aware that their muscular fatigue levels will increase as an operation progresses; therefore, if possible, more complex parts of the operation should be performed as early as possible, or, in the case of a very long operation, a change in surgeon may be necessary.
