Hypothyroidism denotes deficient production of thyroid hormone by the thyroid gland and can be primary (abnormality in thyroid gland itself) or secondary/central (as a result of hypothalamic or pituitary disease). The term 'subclinical hypothyroidism' is used to define that grade of primary hypothyroidism in which there is an elevated thyroid-stimulating ...

Treatment for otosclerosis involves patients' undergoing stapedectomy. Inadvertent damage to the chorda tympani nerve's (CTN's) secretory fibers during stapedectomy can result in inadequate secretory stimulation of the submandibular salivary glands (SMSGs) and sublingual salivary glands (SLSGs). Because most saliva originates from these glands, hyposalivation and subjective xerostomia manifest during resting ...
