Comparing responses with positive versus negative polarity clicks may help separate ABRs from cochlear potentials and alert clinicians to the possibility of an auditory neuropathy. Therefore, absent or abnormal ABRs in the presence of normal otoacoustic emissions need not always implicate a purely "central disorder," but might be consistent with dysfunction between outer hair cells and primary afferent fibers.

Sialendoscopy is safe and effective in managing non-neoplastic salivary gland disorders with low rates of major complications. Knowledge of options to navigate the rate-limiting steps, like dilation of the papilla and careful case selection, are key to successful outcomes.

Gastroesophageal reflux has an important role in the cause of numerous otolaryngologic disorders. Although medical management should remain the mainstay of GER therapy, antireflux surgery provided definitive and successful treatment of potentially life-threatening manifestations of GEROD.

An endoscopic approach to pediatric orbitofacial tumors is safe and effective. Although the risk of nerve injury may be higher, a thorough knowledge of frontotemporal anatomy and careful dissection will minimize this risk. The distinct advantage of an endoscopic approach is the absence of any facial scar in these young patients.
