Hemangiomas of the tympanic membrane are extremely rare. We present the third reported case and, to our knowledge, the first capillary hemangioma of the tympanic membrane. These deep purple polypoid tumors are asymptomatic while small but enlarge slowly to erode adjacent structures. They arise characteristically from the lamina propria of the tympanic membrane without involving the middle ear. ...

The cuticle in the tympanal area of immature crickets, Teleogryllus commodus (Walker), is ultrastructurally indistinguishable from that elsewhere on the prothoracic leg. It is only in the pharate adult that changes associated with development of the tympana first appear. In pharate adults and adults the external layer of the tympana consists of a layer of electron-dense material overlying a lay...

(a) Tympanic membrane was taken as the site of recording temperature because it is having same arterial supply as that of hypothalamus–the thermoregulatory center. The tympanic membrane is supplied by maxillary artery and stylomastoid branch of occipital or the postauricular artery which are the branches of external carotid artery(2), whereas hypothalamus is supplied by branches of internal car...

Introduction: Chronic suppurative otitis media (CSOM) is defined as a chronic inflammation of the middle ear and mastoid cavity, which presents with recurrent ear discharges or otorrhoea through a tympanic perforation. The disease usually begins in childhood as a spontaneous tympanic perforation due to an acute infection of the middle ear known as Acute Otitis Media (AOM). The objective of this...

OBJECTIVES To assess the accuracy of a new noninvasive temporal artery (TA) thermometer in infants; to compare the accuracy of the TA thermometer with that of a tympanic thermometer, using rectal thermometry as the criterion standard; and to compare the tolerability of the TA thermometer with that of the tympanic and rectal thermometers. DESIGN Prospective evaluation of the accuracy of TA and...

Frequency-response curves of the tympanum and lateral body wall (lung area) were measured by laser Doppler vibrometry in three treefrog (Smilisca baudini, Hyla cinerea, Osteopilus septentrionalis) and four dendrobatid frog (Dendrobates tinctorius, D. histrionicus, Epipedobates tricolor, E. azureiventris) species. The high-frequency cut-off of the body wall response was always lower than that of...

Aim: Aim of this study was to describe an effective technique for mastoid cavity obliteration and reconstruction attic region in canal wall down Tympano mastoidectomy for unsafe chronic otitis media and to review its efficacy in producing a dry, low maintenance, small mastoid cavity. Material and method: In this prospective study, 100 patients were selected who were undergoing procedures for ac...
