Temporal bone findings in the late stage of secretory otitis media
Abstract:
The temporal bone findings in a patient with secretory otitis media are presented. One ear had been fitted with tympanostomy tubes for five and the other for three years. Before death the latter ear had been without a tube for two years. Histological study revealed secreting tympanic mucosa with a very high density of goblet cells both in the ear with a ventilating tube in position and in the ear with an intact tympanic membrane. The case represents a late stage of secretory otitis media. It seems that ventilating tubes cause the degeneration and disappearance of subepithelial glands but the effect on goblet cells is less pronounced.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
