Neonatal Nasal Obstruction

medical illustration of Diagram showing the synapse between two neurons (or nerve cells) during excitotoxicity. Excessive amounts of glutamate, a neurotransmitter, is being released from the axon terminal of the presynaptic neuron into the synaptic cleft. The receptors become overactivated, allowing high levels of calcium to enter the neuron, which activates enzymes to damage cell structures like the calcium pump. Excitotoxicity may be involved in CNS injuries and neurological diseases.
Next medical illustration of Balloon dilation and drainage of frontal sinus using XprESS device. The instrument is advanced through the nasal passages. This surgical procedure is performed on patients with sinusitis.
