Differentiation between IgG4-related Mikulicz disease and Sjögren's syndrome: A review case report and literature review.

Rationale: IgG4-related diseases cause lesions in various organs throughout the body. In otorhinolaryngology, IgG4-related Mikulicz's disease is suspected and diagnosed based on the presence of lesions of the head and neck, salivary and lacrimal gland enlargement, and bilateral sinus opacity concentrated on the maxillary sinuses. However, in some cases, it is necessary to consider about differentiation between IgG4-related Mikulicz's disease and Sjögren syndrome.

A Structural Analysis of Tympanic Compartments of the Middle Ear in Patients With Down's Syndrome: A Temporal Bone Study.

Unlabelled: : Hypothesis: There may be findings peculiar to the temporal bones of children with Down's syndrome (DS). The purpose of this study is to investigate the temporal bone histopathology of the children with DS.

Background: Otitis media with effusion is a highly prevalent condition with DS.

Temperature Measurements of the Semicircular Canal During Green Laser Irradiation of the Canal: A Preliminary Study.

Background: Laser irradiation of the semicircular canal (SCC) is a good treatment for intractable benign paroxysmal positional vertigo. However, there were few reports on the temperature changes during laser irradiation.

Objective: To measure the internal temperature of the SCC and vestibule during green laser irradiation of the SCC and investigate morphologic changes using human temporal bones.

Quantitative assessment of vestibular otopathology in granulomatosis with polyangitis: A temporal bone study.

Objective: To investigate the temporal bone histopathology of vasculitis, especially in the vestibular organs, in granulomatosis with polyangitis (GPA).

Methods: Using light and differential interference contrast microscopy, we examined 12 human temporal bones from six deceased GPA patients and 12 histopathologically normal human temporal bones from six deceased age-matched patients.

Results: In the GPA group, three patients had undergone tympanostomy tube placement.

Structural Analysis of Tensor Tympani Muscle, Tympanic Diaphragm, Epitympanum, and Protympanum in Menière's Disease: a Human Temporal Bone Study.

Hypothesis: We hypothesized that there would be significant anatomic differences of the tensor tympani muscle (TTM), tympanic diaphragm, epitympanum, and protympanum in patients with versus without Menière's disease.

Background: The effects of tenotomy on Menière's disease suggested it relieves the pressure on the inner ear of the contraction of the TTM and of negative middle ear pressure.

Methods: Using human temporal bones from patients with Menière's disease, two studies were conducted.
