It may also be acquired, seen in glassblowers due to continual forced expiration producing increased pressures in the larynx which leads to dilatation of the laryngeal ventricle (sinus of Morgagni).
When Valsalva was transferred to Parma Morgagni succeeded to his anatomical demonstratorship.

Among his more celebrated pupils were Antonio Scarpa (who died in 1832, connecting the school of Morgagni with the modern era), Domenico Cotugno (1736–1822), and Caldani (1725–1813), the author of the magnificent atlas of anatomical plates published in 2 volumes at Venice in 1801–1814.
The epoch-making work of Morgagni, based on clinical-anatomical observations, provides a definitive insight into the location of the condition and into many pathologic features.
