OBJECTIVE To describe the technical parameters and findings of blink reflex (BR) and laryngeal adductor reflex (LAR) in children during the intraoperative neuromonitoring (IONM) of brainstem and posterior fossa surgery. METHODS Retrospective review of 17 patients (1-16 years old) who underwent posterior fossa surgery with multimodal IONM, including BR and/or LAR (tube-based methodology with adhesive electrodes), CoMEPs, and free-running EMG. We analyzed the elicitability of each modality, number of intraoperative events and the first modality to raise an alarm.

OBJECTIVE To analyze the contribution of brainstem reflexes in intraoperative neuromonitoring (IONM): blink reflex (BR), H masseter reflex (H), trigeminal hypoglossal reflex (THR), and laryngeal adductor reflex (LAR) during the monitoring of brainstem and posterior fossa surgery, to other well-known cranial nerve monitoring techniques for the trigeminal, facial, vagus and hypoglossal nerves, such as corticobulbar motor evoked potentials (CoMEPs) and free-running EMG.
