Thixotropy of levator palpebrae as the cause of lagophthalmos after peripheral facial nerve palsy.
Patients with facial nerve palsy are at risk of developing corneal ulceration because of lagophthalmos (incomplete closure of the affected eyelid). Lagophthalmos could result from thixotropy of the levator palpebrae muscle--that is, the formation of tight crossbridges between the actin and myosin filaments of the muscle fibres causing stiffness of the muscle--rather than from paralysis of the o...
متن کاملPeripheral Facial Nerve Palsy after Therapeutic Endoscopy
Peripheral facial nerve palsy (FNP) is a mononeuropathy that affects the peripheral part of the facial nerve. Primary causes of peripheral FNP remain largely unknown, but detectable causes include systemic infections (viral and others), trauma, ischemia, tumor, and extrinsic compression. Peripheral FNP in relation to extrinsic compression has rarely been described in case reports. Here, we repo...
متن کاملLagophthalmos after facial palsy: current therapeutic options.
As the facial nerve carries sensory, motor and parasympathetic fibres involved in facial muscle innervation, facial palsy results in functional and cosmetic impairment. It can result from a wide variety of causes like infectious processes, trauma, neoplasms, autoimmune diseases, and most commonly Bell's palsy, but it can also be of iatrogenic origin. The main ophthalmic sequel is lagophthalmos....
متن کاملSurgical anatomy of the levator palpebrae insertion.
THE text-book description of the anatomy of the upper eyelid with particular reference to the septum orbitale (palpebral fascia) and especially the insertion of the levator muscle is unnecessarily vague or complicated from the surgical point of view. Thus the septum orbitale is described by some authors as arising from the orbital margin and ending where it blends with the aponeurosis of the le...
متن کاملCysticercosis of the levator palpebrae superioris.
Fig. 1A. Complete ptosis of the right eye at presentation. Dear Editor, Cysticercosis cellulosae, the larval form of the pork tapeworm Taenia solium, causes cysticercosis, in which humans serve as the intermediate hosts in the parasite life cycle. Cysticercosis is endemic in developing regions such as South America, India and China.1,2 However, a rise in a cysticercosis has been observed in ind...
