Developmental anatomy of the tympanic membrane and its relation with the malleus handle was studied using fetal temporal bone specimens. During 16th week of gestation the intermediate mesodermal layer which consist of two laminas-radial layer laterally and circular layer medialy-originate around the tympanic ring as loose connective tissue. The inner circular layer hold the malleus handle and fuses with the periosteum (or perichondrium). The outer radial layer which is thicker than the outer circular layer contains copious blood vessels. After 30th week of gestation conjunction between malleus handle and inner circular layer become loose and lost except outer surface of the malleus handle. Only at the tip of the malleus periosteum is thick and hold by the circular layer which seems to become the umbo.

Taste disorders can be caused by various factors, including zinc deficiency, adverse drug reactions, cold and xerostomia, and the number of patients seeking medical assistance for such disorders is increasing. However, because taste disorders are often difficult to treat, some medical institutions will not treat these complaints.In the Department of Otolaryngology at Osaka Dental University Hospital, a clinic was opened on September 1, 2004, to treat patients with taste disorders.We treated 1 outpatient who lost one side of parotid gland due to malignancy, then lost the function of the remaining salivary gland due to Sjögren's syndrome.Subjects comprised 17 patients complaining of taste disorders with xerostomia without subjective symptoms of other otolaryngological diseases.In the present study, 4 patients were prescribed zinc by another physician, but only 2 patients actually displayed zinc deficiency. Zinc administration did not improve symptoms in any of the patients.According to the diagnostic criteria for xerostomia in our department, 17 patients had xerostomia, and 4 of these 17 patients were diagnosed with Sjögren's syndrome. These patients were instructed to gargle with cevimeline hydrochloride, and taste sensation improved in 12 patients.We have examined 17 patients to data and consider this number insufficient to draw definitive conclusions but the data we have currently suggests to the following conclusions:1. Latent Sjögren's syndrome should be suspected in patients presenting with taste disorder with xerostomia.2. In taste disorder patients with xerostomia, gargling with cevimeline hydrochloride appears very useful.3. One patient had lost a side of salivary gland, and Sjögren's syndrome caused loss of function of the remaining salivary gland. In this patient, favorable results were also obtained by gargling with cevimeline hydrochloride.
