PURPOSE: It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients. METHODS: Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a 30-mm long piece of skin, while allowing the 5 mm wide distal part of the skin to remain attached, to mimic a skin flap (hereafter called a "skin flap")...

BACKGROUND: Understanding the anatomy of the lower eyelid and the lid-cheek junction is important for surgical and non-surgical approaches. It is important to understand the correlation between the clinical presentation and the individual anatomy to direct an adequate treatment. METHODS: A review of the literature based on the authors experience combined with anatomical dissections was conducted to reveal the current concepts of the surgical and non-surgical anatomy...

Synkinetic movements are common among patients with incomplete recovery from facial palsy, with reported rates ranging from 9.1% to almost 100%. The authors propose the separation of the neural stimulus of the orbicularis oculi from that of the zygomatic muscular complex to treat eyelid closure/smiling synkinesis. This technique, associated with an anastomosis between the masseteric nerve and a central branch of the facial nerve, as well as with the use of a cross-facial nerve graft, resolves most of the spasms of the midface musculature, leading to a more relaxed tone when the mimic muscle is at rest and enhancing muscle excursion during voluntary and spontaneous smiling...

Epithelioid hemangioendothelioma (EHE) is an infrequent vascular tumor that has an intermediate prognosis between the prognosis of the angioma and that of the angiosarcoma. Its evolution is characterized by a tendency to recurrence and metastases. EHE has been reported in locations such as: lungs, liver, bone and soft tissues. There are very few reports of cases involving the head and neck region. The occurrence of EHE in the orbital region and/or the eyelid is extremely rare. The authors report a case of EHE in the right upper eyelid...

Mucinous carcinomas of the periorbital area are very rare malignant tumors and can be primary or secondary to metastasis. Primary mucinous carcinomas of the eyelid include, most commonly, primary cutaneous mucinous carcinoma with endocrine mucin-producing sweat gland carcinoma being a remote second.[1,2,3,4] To our knowledge, primary mucinous carcinomas of conjunctiva or lacrimal gland elements have not been described in the literature.[5,6] Metastatic carcinoma from visceral sites should also be considered in the differential diagnosis...

BACKGROUND: It is difficult to determine the amount of eyelid lift in levator resection surgery for congenital ptosis, especially when the surgery is performed under general anesthesia. We aim to introduce an objective and steady method with which to adjust eyelid height, and to identify other factors to be considered during surgery. METHODS: This is a retrospective, observational study of 110 eyes from 78 patients who underwent levator resection surgery for congenital ptosis...

BACKGROUND: Alveolar Soft Part Sarcoma is a rare malignant tumor of uncertain histogenesis, representing 0.5-1% of all soft tissue tumors. It occurs predominantly in head and neck regions, especially the orbit and the tongue, in infants, causing no specific symptoms for an extended period of time. CASE: A four year old girl was brought to consultation because of persistent swelling of her left upper and lower eyelid for the past six months. A 4 mm proptosis was noted on her left eye with significant upwards displacement of the globe...

A 50-year-old female presented with bilateral retinitis pigmentosa (RP) and acute angle closure (AAC) with fixed mid-dilated pupil and high intraocular pressure (IOP) in the left eye following left side periorbital botulinum toxin A injection for blepharospasm. Glaucomatous optic neuropathy and retinal nerve fiber layer defect were observed in the affected eye using optical coherence tomography although the IOP was maintained at <21 mmHg after the treatment. Botulinum toxin acts at the cholinergic synapse and inhibits acetylcholine release; hence, it can cause transient mydriasis and may lead to AAC in high-risk populations such as patients with RP...

With the rapid growth of the stem cell biology field, the prospect of regenerative medicine across multiple tissue types comes closer to reality. Several groundbreaking steps paved the way for applying stem cell biology to the several subfields within ophthalmology and oculoplastic surgery. These steps include the use of stem cell transplants as well as studies of various ophthalmologic pathologies at the molecular level. The necessity of stem cell transplant is readily apparent, having already been used for several studies such as artificial lacrimal gland design and eyelid reconstruction...

A 42-year-old woman presented with chronic history of left red eye for more than 12 months, treated with difference topical medication but without response. Ocular external examination demonstrated a firm palpable mass in the medial portion of the lower eyelid and slit-lamp evaluation of the lesion showed an ulcerated conjunctival nodule, keratin secretor. CT of the orbits revealed left-sided orbital mass located anteriorly, inferiorly and medially in the orbit, adjacent to the globe and orbit walls. Incisional biopsy of the lesion was consistent with invasive squamous cell carcinoma of the conjunctiva...

Congenital cranial dysinnervation disorders (CCDDs) comprise a heterogeneous spectrum of diseases characterized by congenital, non-progressive impairment of eye, eyelid and/or facial movements including Möbius syndrome, Duane retraction syndrome, congenital ptosis, and congenital fibrosis of the extraocular muscles. Over the last 20 years, several CCDDs have been identified as neurodevelopmental disorders that are caused by mutations of genes involved in brain and cranial nerve development, e.g. KIF21A and TUBB3 that each plays a pivotal role for microtubule function...

Lipoblastoma is a rare tumor that is not commonly seen in the orbit. The authors present clinical features, histopathologic findings, changes in the radiologic findings over time, and the radiological-pathological correlation of orbital lipoblastoma in an infant. A 3-month-old male infant presented with a palpable mass on the left upper eyelid. The patient was observed for 1 year with magnetic resonance imaging. At the age of 15 months, the patient underwent excisional biopsy. Histopathologic examination showed features of hypocellular lobules with a mixture of adipocytes of various stages of maturity and myxoid stroma separated by prominent fibrous septa, confirming a diagnosis of orbital lipoblastoma...

REVIEW
Armando Retana
Facial cosmetic surgery techniques are constantly updated to meet the expectations of patients who demand less invasive procedures and less recovery time. Current trends in lower eyelid surgery call for periorbital fat repositioning instead of excision of fat. Controversies still exist in chin augmentations regarding osseous genioplasty versus alloplastic chin implant. The benefits, disadvantages, and considerations of these procedures are discussed.

Immunoglobulin G4-related disease (IgG4-RD) is a comparatively new condition that may involve more than one organ. The lack of characteristic, pathognomonic clinical symptoms may delay the diagnosis of this disease. The diagnosis is based upon clinical manifestation, elevated serum levels of IgG4 and histopathologic examination with immunohistochemical staining to reveal infiltration of IgG4-positive plasma cells. The first line treatment is oral glucocorticoids. A CASE REPORT: 38-year-old woman with Hashimoto disease, chronic sinusitis and chronic hepatitis of unknown etiology was admitted to the Department of Endocrinology because of moderate eyelids swelling accompanied by redness for 3 years...

Over a 2 year period a 32-year-old woman developed swellings of all 4 eyelid margins accompanied by complete loss of eyelashes. An inflammatory dermatologic condition was considered the most likely cause. A full thickness right lower eyelid biopsy revealed a multinodular lymphoid tumor at the eyelid margin which immunophenotypically and genetically was diagnosed as an extranodal marginal zone lymphoma. The mode of presentation of the disease was considered to be most unusual, as was its B cell lineage, since the majority of primary cutaneous lymphomas are of T-cell origin...
