Abstract
The development of the TMD test has offered a mechanism of repeated ambulatory non-invasive assessment of intracranial pressure (ICP). Previous studies have demonstrated that TMD measurements correlates with direct ICP measurements (Reid et al. 1990) (Ernst et al. 1995). Since the test depends on the patency of the cochlea aqueduct, and since this is more likely to be patent in children than adults (Wlodyka. 1978), the paediatric population is particularly suitable for assessment of the TMD test. When the patient has had a previous baseline TMD test performed, TMD will accurately predict raised ICP in children with spina bifida and blocked CSF shunts (Moss et all 991, Sugarman 1994). The detection of normal ICP by TMD assessment has been shown to enable shunt surgery to be avoided (Sugarman 1994).
