According to a version of the story in the Iliad scholia (found nowhere else), when Zeus swallowed Metis, she was pregnant with Athena by the Cyclops Brontes.Although described by Hesiod as "having very violent hearts" (ὑπέρβιον ἦτορ ἔχοντας), and while their extraordinary size and strength would have made them capable of great violence, there is no indication of the Hesiodic Cyclopes having behaved in any other way than as dutiful servants of the gods.Walter Burkert suggests that groups or societies of lesser gods, like the Hesiodic Cyclopes, "mirror real cult associations (thiasoi) ... It may be surmised that smith guilds lie behind Cabeiri, Idaian Dactyloi, Telchines, and Cyclopes." Homeric Cyclopes
In an episode of Homers Odyssey (c. 700 BC), the hero Odysseus encounters the Cyclops Polyphemus, the son of Poseidon, a one-eyed man-eating giant who lives with his fellow Cyclopes in a distant land. The relationship between these Cyclopes and Hesiods Cyclopes is unclear. Homer described a very different group of Cyclopes, than the skilled and subservient craftsman of Hesiod. Homers Cyclopes live in the "world of men" rather than among the gods, as they presumably do in the Theogony. The Homeric Cyclopes are presented as uncivilized shepherds, who live in caves, savages with no regard for Zeus. They have no knowledge of agriculture, ships or craft. They live apart and lack any laws.The fifth-century BC playwright Euripides also told the story of Odysseus encounter with Polyphemus in his satyr play Cyclops. Euripides Cyclopes, like Homers, are uncultured cave-dwelling shepherds.
In severe cases, dilation and laser treatment only works temporarily, and the condition frequently recurs. Repeated procedures, especially stents, come with the risk of increasing the damaged area. Also, laser resection has a risk of damaging the cartilage underneath. For this reason, surgery is typically done. In addition to surgery, mitomycin can be applied topically and glucocorticoids can be injected.Idiopathic cases are usually treated via endoscopic balloon dilation, and dilation may be improved by injecting corticosteroids. It is also the safest and main treatment in pregnant women. It allows dilation via noninvasive measures such as expanding a balloon catheter via ventilation. Prognosis
The condition frequently recurs after dilation. The prognosis after surgery is good if it is done carefully to avoid complications. Epidemiology
The condition has decreased in frequency over time, due to improved management of people on a ventilator. The condition occurs in around 1% of endotracheal tube users. References
