A Consistent, Reliable Landmark to Assist in Placement of Orbital Floor Reconstruction Plates After Blowout Fractures.

Objective: To define a reliable and consistent landmark, the superior posterior wall of the maxillary sinus, and to describe how this landmark can be used when repairing orbital floor fractures.

Methods: Retrospective chart review. Patients >18 years old diagnosed with unilateral orbital floor and/or zygomaticomaxillary complex fractures.

Outpatient Surgical Management of Orbital Blowout Fractures.

There is ample investigation into the optimal timing and approach to orbital blowout fracture (OBF) repair; however, less attention has been directed toward postoperative care. This is a multicenter IRB-approved retrospective review of patients with OBF presenting to our study sites between November 2008 and August 2016. Those with isolated OBF, over 18 years of age, and who had not suffered additional facial injuries or globe trauma were included.

Correction of Lower Eyelid Retraction with En Glove Placement of Porcine Dermal Collagen Matrix Implant.

The authors conducted a retrospective case series of patients undergoing a lateral tarsal strip procedure with "en glove" placement of an acellular porcine dermal collagen matrix for correction of mild to moderate lower eyelid retraction. A detailed description of this minimally invasive technique with retrospective analysis of outcomes is provided. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

Restrictive Strabismus Following Frontotemporal-orbitozygomatic Craniotomy.

The frontotempotal-orbitozygomatic craniotomy (FTOZ) is a standard approach for large sphenoid wing meningiomas (SWMs). Nevertheless, resection of these tumors is not without ophthalmologic risks. This series presents two patients with acute postoperative restrictive strabismus following tumor resection and orbital wall reconstruction.

Diagnosing Distensible Venous Malformations of the Orbit With Diffusion-weighted Magnetic Resonance Imaging.

Purpose: To compare the diffusion-weighted imaging of nonthrombosed distensible venous malformations of the orbit with that of other histologically-proven orbital tumors.

Design: Retrospective case-control study.

Methods: Patients with nonthrombosed distensible venous malformations of the orbit and patients with other histologically-proven orbital tumors were selected for chart review.

Open globe injury with an interesting intra-ocular foreign body.

Cases of penetrating ocular trauma due to osseous material are limited, so reported incidents are valuable in determining outcomes and proper treatment courses. We report a case of an open globe injury of the left eye with an intraocular foreign body occurring after a firework exploded in the hand of a 22-year-old man. The patient presented with light perception vision in the injured eye with a full-thickness limbal laceration and dense hyphema obscuring fundoscopy.

Primary hepatoid adenocarcinoma of the orbit.

Purpose: To report a case of primary hepatoid adenocarcinoma of the orbit.

Observations: An adult patient was referred for evaluation of an orbital mass. Histopathology of the orbital biopsy indicated a carcinoma with hepatoid features.

Persistent Upgaze Restriction after Orbital Floor Fracture Repair.

Here we present two cases of marked postoperative upgaze restriction after successful repair of orbital floor fracture and release of inferior rectus entrapment. In both cases, follow-up imaging showed enlargement of the inferior rectus, and gradual resolution of gaze limitation was observed over several months of conservative management. Thus, in patients with postoperative findings suggestive of residual inferior rectus entrapment, follow-up imaging is indicated prior to returning to the operating room.

Lacrimal Sac Smooth Muscle Tumor of Uncertain Malignant Potential.

A 13-year-old male presented with recurrent left nasolacrimal duct obstruction following endoscopic dacryocystorhinostomy 4 years prior at an outside institution. The past medical history was significant for stage IV neuroblastoma, diagnosed at age 2, requiring surgical resection, induction chemotherapy, autologous bone marrow transplantation and radiation, currently in remission. Preoperative CT scan demonstrated a 2 cm ovoid mass centered in the left lacrimal fossa, consistent with dacryocystocele; however, a solid tumor could not be ruled out.

Paranasal Sinus Mucocele as a Late Complication of Dacryocystorhinostomy.

A 50-year-old female presented with a slowly enlarging painless mass of the right medial canthus. The past surgical history is significant for external dacryocystorhinostomy for acquired nasolacrimal duct obstruction 10 years prior and subsequent endoscopic and external revisions. Imaging revealed a large fronto-ethmoidal sinus mucocele extending into the right medial orbit.

Delayed periocular hemorrhage after upper blepharoplasty.

Periocular and orbital hemorrhage are rare complications of blepharoplasty, with a reported incidence of 0.055%. These complications are even less common more than 48 h after surgery.

An aggressive sphenoid wing meningioma causing foster kennedy syndrome.

Foster Kennedy syndrome is a rare neurological condition with ophthalmic significance that can manifest as acute visual loss. It is classically characterised by unilateral optic nerve atrophy and contralateral papilledema resulting from an intracranial neoplasm. Physicians should consider Foster Kennedy syndrome in patients who present with visual loss and who have a history of intracranial neoplasm.

Clinical, radiographic, and audiometric predictors in conservative management of vestibular schwannoma.

Objective: Vestibular schwannomas (VS) can be managed by observation. The goals were to examine clinical, radiographic, and audiometric variables at presentation and during observation that may predict which patients fail conservative management.

Methods: A retrospective chart review was performed of 202 patients who elected observation primarily.

Frequency and phenotypic implications of mitochondrial DNA mutations in human squamous cell cancers of the head and neck.

Mitochondrial genomic mutations are found in a variety of human cancers; however, the frequency of mitochondrial DNA (mtDNA) mutations in coding regions remains poorly defined, and the functional effects of mitochondrial mutations found in primary human cancers are not well described. Using MitoChip, we sequenced the whole mitochondrial genome in 83 head and neck squamous cell carcinomas. Forty-one of 83 (49%) tumors contained mtDNA mutations.
