OBJECTIVE: Hypothyroidism is defined as an underactive thyroid gland and one of the reasons for inadequate stimulation of thyroid is dysfunction of the hormone regulating brain centers. Olfaction disorders have been considered as a problem in hypothyroidism. It has been hypothesized that olfaction disorders reduce olfactory stimulation and diminished olfactory stimulus may trigger hypothyroidism. In this study, an examination was made of the thyroid hormone levels, histologic features of thyroid glands, and vagal nerve network degradation in an experimental animal model of olfactory bulbectomy (OBX).
