#1
David R Jordan, Bazil Stoica
The gracillimus orbitis muscle is an anomalous, accessory, or supernumerary extraocular muscle that, although is rarely seen clinically in the human orbit, has been identified in 5% to 14% of dissected cadaver orbits. It arises from the medial surface of the levator near its origin and runs forward between the levator and superior oblique muscles resembling one of the other extraocular muscles. More anteriorly, it becomes thinner, less well defined, and mostly fibrous. Its major insertion is into the fascia surrounding the trochlea, while other fibers may travel to the supratrochlear artery, intermuscular septum, the levator or medial rectus muscle, and the fascia surrounding the superior ophthalmic vein...

PURPOSE: Epiphora is sometimes associated with an absent or occluded lacrimal drainage punctum (or puncta). This study uses noninvasive "enhanced depth" anterior segment optical coherence tomography (OCT) to give improved characterization and understanding of absent or fully occluded puncta and the underlying canaliculus. METHODS: Anterior segment spectral domain OCT images were collected prospectively from 9 lower puncta of 6 patients with epiphora and absent or fully occluded puncta, not amenable to dilation in clinic, to see if a canaliculus was visible on OCT imaging below the occluded punctum...

BACKGROUND: Ptosis after botulinum toxin injection is a disturbing complication. Decongestant and antiglaucoma eyedrops are frequently prescribed for temporary improvement of eyelid ptosis. Although frequently cited on informal communications, the effect of these drugs on eyelid position has never been compared in a formal study. OBJECTIVE: To measure the effect of low-concentration, nonmydriatic selective alpha agonist eyedrops on upper eyelid position. METHODS AND MATERIALS: This nonrandomized clinical trial enrolled 20 healthy subjects aged 18 to 50 years...

This case with unilateral complete blepharoptosis and slight limitation of upgaze as ocular findings due to midbrain infarction represents an unusual form of intra-axial oculomotor nerve involvement. A 65-year-old man was admitted with acute unilateral ptosis of the left eyelid and gait ataxia. He had chronic hypertension in the medical history. The neurologic examination revealed that he had a complete ptosis of the left eyelid, slight limitation of elevation in the left eye, bilateral dysmetria, and gait ataxia...

Jennifer Murdock, Preeti J Thyparampil, Michael T Yen
Chronic progressive external ophthalmoplegia (CPEO) is a mitochondrial myopathy with slowly progressive, often symmetric blepharoptosis and limitation of ocular motility in all directions of gaze. The authors present an unusual case of CPEO that initially presented with the unique features of markedly asymmetric facial weakness and the lack of blepharoptosis. However, over the subsequent three decades, the patient developed progressive facial and eyelid dysfunction more consistent with a classical description of CPEO...

A 23-year-old male presented to the emergency department with right eye pain, right upper eyelid ptosis, blurry vision, and binocular diplopia that developed immediately after he bent over in a parking lot and the antenna of a car penetrated his right upper eyelid. An extensive workup was performed, and he was found to have an isolated traumatic oculomotor nerve palsy with pupil involvement. No other ocular findings of a traumatic injury were present. The patient was observed for 14 months, during which he continually improved, with almost complete resolution of his diplopia, anisocoria, and ptosis...

BACKGROUND: Midface advancement is a keystone intervention in the treatment plan of syndromic hypoplasia of the midface. Although earlier authors had been using a combination of smaller incisions to acquire enough access to perform the different osteotomies, Tessier popularized the bicoronal incision. This approach can be time-consuming however and leaves an ear-to-ear scar. The authors describe an endoscopically assisted piezo-electric Le Fort III osteotomy performed through minimal invasive access...

BACKGROUND: The B2 receptor antagonist icatibant is approved for treatment of attacks of hereditary angioedema. Icatibant has been reported to decrease time-to-resolution of angiotensin-converting enzyme (ACE) inhibitor-associated angioedema in one study of European patients. METHODS: Patients with ACE inhibitor-associated angioedema (defined as swelling of lips, tongue, pharynx or face during ACE inhibitor use and no swelling in the absence of ACE inhibitor use) were enrolled at Vanderbilt University Medical Center from October 2007 through September 2015 and at Massachusetts General Hospital in 2012...

E V Boiko, V F Chernysh
: Ophthalmic literature currently lacks definiteness in classifying surgeries aimed at eyelid closure. In Western countries the term tarsorrhaphy is most commonly used, while in Russia another term - blepharorhaphy - is widely accepted. The latter seems more appropriate as the sutures are passed through all palpebral layers, not just the cartilage. It has also been suggested that temporary blepharorhaphy, which implies that we use only sutures to bring the eyelids together, and therefore, the procedure cannot be permanent, should be called simple blepharorhaphy...

N R Marchenko
Treatment of allergic diseases of eyelids and conjunctiva (conjunctivites and blepharoconjunctivites) often presents difficulties due to peculiarities of their pathogenesis - allergic and vascular reactions, disorder of lacrimal production, meibomian gland dysfunction, and possible bacterial contamination. It has been suggested to use Ocumethyl, which contains zinc sulfate (binding, drying, anti-inflammatory, and antiseptic effect), diphenhydamine hydrochloride (an Н1-antihistamine that decreases capillary permeability and helps resolve conjunctival and eyelid edema), naphazoline hydrochloride (a sympathomimetic notable for its strong, rapid, and long-lasting vasoconstrictive effect), and methylene blue (antiseptic effect, disintoxication, and antioxidant activity)...

Synthetic biodegradable scaffolds such as polylactic acid coated polyglycolic acid (PLA-PGA) are especially suitable for engineering shaped cartilage such as auricle, but they induce a serious inflammatory reaction particularly in the immunologically aggressive subcutaneous site, leading to resorption of the engineered autologous cartilage. Our previous study in a rabbit model has demonstrated 2 weeks of in vitro precultivation could significantly alleviate the post-implantation inflammation induced by PLA-PGA engineered cartilaginous grafts, but reproduction of this result failed in a preclinical goat model...

#18
Wolfgang Funk
BACKGROUND: Producing youthful facial appearance by face-lifting often comes along with an undesired loss of patient's individual phenotype. This may result from insufficient preservation of retaining ligaments, the "guardians of facial identify," and from severance of the intersegmental connections of the superficial musculo-aponeurotic system (SMAS), which tether, structure, and compartmentalize facial soft tissue into defined, relevant anatomical zones. METHODS: The technique reported here preserves most retaining ligaments...
