BACKGROUND: Silent sinus or imploding antrum syndrome is a very rare condition, consisting of a usually asymptomatic spontaneous collapse of the sinus walls and floor of the orbit. It is associated with negative pressures, and when this occurs, it presents with manifestations such as enophthalmos, hypoglobus, and tilt flow orbital floor. As its incidence is very low, it is frequently missed as a diagnosis, and in fact there are currently fewer than 150 cases reported in the literature...

PURPOSE: To study the types of acquired restrictive strabismus treated in a tertiary hospital and the outcome of treatment with botulinum toxin. METHODS: We performed a 10-year retrospective study of patients with restrictive strabismus aged ≥18 years who were treated with botulinum toxin. Treatment was considered successful if the final vertical deviation was ≤5 PD, horizontal deviation ≤10 PD, with no head turn or diplopia. RESULTS: We included 27 cases (mean age, 61...

Neurofibroma is a slow growing benign tumour of the peripheral nerve sheath which is frequently associated with neurofibromatosis type 1 (Prakash et al., 2014). Isolated solitary occurrence of neurofibroma in the maxillary sinus is rare with only 29 reported cases in the literature. We present a rare case of a 70-year-old gentleman who was referred to ENT with a right maxillary sinus neurofibroma with extension into the right inferior orbit. He has significant proptosis, ptosis, and limitation in abduction of the right eye...

Osteosarcoma in the craniofacial region is rare. A 43-year-old female, the patient, self-detected a 3-cm tumor of the right frontoparietal region 4 months before. An incisional biopsy was performed and a osteosarcoma was reported. At admission, a 4 × 5 cm tumor was present on the right frontoparietal region, without extending to the orbital region but the patient underwent surgery 2 months after admission. The delay was due to 2 episodes of upper respiratory tract infection that required resolution. At the time of surgery the tumor measured 8 × 9 cm...

OBJECTIVE: With orbital floor fracture incidence rates increasing year by year, many patients require surgical treatment to improve diplopia, limitation of extraocular muscle movement (EOM), enophthalmos, and midface appearance. With the use of high-density polyethylene, titanium screws, titanium plate, and titanium mesh to repair an orbital floor fracture, enophthalmos and midfacial deformity correction procedures have made great progress. However, attenuating diplopia and the limitation of EOM are still difficult problems to prevent...

Two surgical procedures for ectropion correction are compared: the widespread "lateral tarsal strip" and the more recently introduced "tarsal belt" techniques. A retrospective interventional patient series of 40 patients with mono or bilateral ectropion are investigated.Distances of lower lid margin from interpupillary line before surgery and after 1, 6, 12, and 24 months in tarsal belt and lateral tarsal strip surgical procedure are compared. The postoperative distance is reduced in both the groups of patients, but as regard the tarsal belt the amount of correction is greater and more stable over time and this difference is statistically significant...

Blow-in fracture of the zygomaticomaxillary complex that was displaced into the orbital cavity could be associated with ophthalmologic injuries, ranging from visual acuity to ocular motility limitation. Appropriate reduction and realignment of the fractured bone is necessary as early as possible for recovery of function and esthetics. However, limitation of accessibility and visibility makes it difficult for delicate surgery and increases the risk of damage of adjacent anatomic structures, such as optic nerve and extraocular muscles...

BACKGROUND: Sleep is integral to biologic function, and sleep disruption can result in both physiological and psychologic dysfunction including cognitive decline. Surgery activates the innate immune system, inducing neuroinflammatory changes that interfere with cognition. Because surgical patients with sleep disorders have an increased likelihood of exhibiting postoperative delirium, an acute form of cognitive decline, we investigated the contribution of perioperative sleep fragmentation (SF) to the neuroinflammatory and cognitive responses of surgery...

INTRODUCTION: When prepping for navigation surgery, a reference frame must be fixed to the patient's head with a Mayfield clamp, bone anchor, headset, or headband. Fixation of the clamp or bone anchor with a screw or head pins is invasive, whereas use of a headband or headset is noninvasive. However, during orbital surgery for blowout fractures or orbital tumors, surgeons or instruments can interfere between the reference frame and the optical tracking navigation system, even if using noninvasive fixation...

Introduction Due to the close anatomical relationship between the paranasal sinuses and the orbit, involvement or injury of the orbit from paranasal sinuses procedures may occur. Objectives We aimed to study the early and delayed effect of endoscopic sinus surgery on intraocular pressure (IOP). Methods We included in the study 38 patients with chronic rhinosinusitis (CRS), undergoing FESS. We performed FESS with the standard anterior to posterior approach. We measured IOP at the same time one day before surgery as well as day 1 and 6 weeks after surgery...

BACKGROUND: The ability to correct unnatural-appearing, high, and deep double eyelid folds has been limited by the lack of redundant upper eyelid skin and the presence of prior incision line scars in patients. METHODS: From January 2000 to September 2011, 256 patients with high and deep double eyelid folds underwent our fold-lowering procedure. The first dissection was made at the superficial layer between the orbicularis oculi muscle and orbital septum/retroorbicularis oculi fat...

OBJECTIVE: Acute invasive fungal sinusitis (AIFS) is a frequently fatal infection for which extensive and debilitating surgical debridement is a mainstay of therapy. Resulting defects are often composite in nature, mandating free tissue-transfer reconstruction. Outcomes data for free flap reconstruction are limited. The purpose of this study was to examine surgical outcomes and survival in patients undergoing free flap transfer following invasive fungal sinusitis. STUDY DESIGN: Retrospective case series...

Intravenous glucocorticoids are used for Graves' orbitopathy, alone or associated with/followed by additional treatments (orbital radiotherapy, orbital decompression, palpebral or eye surgery). However, the relation between associated/additional treatments and other variables with Graves' orbitopathy outcome following intravenous glucocorticoids is not clear. Thus, the present study was conducted to investigate retrospectively the impact of associated/additional treatments and other variables on Graves' orbitopathy outcome after intravenous glucocorticoids...

We describe 2 paediatric patients who developed large orbital conjunctival epithelium-lined inclusion cysts postsurgery. Case 1 underwent Ahmed glaucoma valve implant surgery 8 months ago and case 2 underwent strabismus surgery 7 years ago. Both cases had either symptomatic strabismus or a mass causing some degree of proptosis or incomitance due to lesions in the intraorbital space. Following total excision of the cysts all associated symptoms were resolved. Conjunctival cysts following ocular surgery can develop anywhere in the anterior segment; however, large orbital cysts following anterior segment surgery are quite rare...
