RESUMO
The sternohyoid, sternothyroid, thyrohyid and omohyoid constitute the infrahyoid group of anterior neck muscles. All these muscles are supplied by Ansa crvicalis related to the anterior wall of carotid sheath. During regular cadaveric dissection in the Department of Anatomy at AIIMS, Bhubaneswar, a case of right sided absence of sternohyoid muscle with left sided tendinous superior belly of omohyoid muscle was found. Though literature survey shows the tendinous belly (or absence) of superior belly of omohyoid muscle, but its presence in combination with absence of opposite side sternohyoid muscle is hardly reported. The omohyoid muscle has effect on intracerebral venous hemodynamics. Developing from a common muscle primodium the infrahyoid muscle group shows a number of variations. Because of increased use of Infrahyoid myocutaneous flaps for medium sized head and neck reconstruction surgery this knowledge will be helpful for handling and selecting a flap.
RESUMO
Heerfordt's syndrome is defined as a combination of facial palsy, parotid swelling, uveitis and fever in sarcoidosis cases. Heerfordt's syndrome as a cause of facial palsy is very rare. We report a case of alternating facial nerve palsy in a 52-year-old female initially treated for Bell's palsy. The patient was referred to the All India Institute of Medical Sciences, Bhubaneswar, India, in January 2013 for clinical evaluation. She was found to have a parotid swelling and anterior intermediate uveitis. A pathoradiological evaluation suggested sarcoidosis and a final diagnosis of Heerfordt's syndrome was made. Steroid treatment was initiated which led to an improvement in the facial palsy and uveitis as well as the disappearance of the parotid swelling with a corresponding decrease in angiotensin-converting enzyme levels. An English literature review was carried out to analyse the varied presentation of this syndrome. The analysis focused on presenting symptoms, biochemical markers and radiological findings of Heerfordt's syndrome cases
