In this study, details of the infraorbital nerve's (ION's) anatomical course variants were compared using computed tomography (CT), and relationships between the variants and fracture patterns in the orbital floor were investigated. Fifty-two normal individuals and 50 patients with unilateral isolated orbital floor fractures were enrolled in this study. Four measurements in normal individuals and five measurements in fracture patients were obtained in parasagittal sections. The anatomical variations of the ION were categorized into three types according to the classification by Ferences et al...

PURPOSE: To determine the national estimates, demographics and costs of inpatient eye care in the United States (US). DESIGN: Retrospective cross-sectional study. METHODS: National Inpatient Sample (NIS), a representative sample of all US community hospitals, was used to analyze inpatient admissions with a primary ophthalmic diagnosis from 2001 to 2014. National estimates of the most prevalent diagnoses were determined, and descriptive statistics were calculated for demographics and costs...

PURPOSE: The purpose of the present study was to clarify the reasons for, types of, and degree of involvement of the orbital wall and the severity of orbital fractures in geriatric patients and to compare the differences between geriatric and younger adult patients. MATERIALS AND METHODS: A retrospective case-control study of geriatric patients aged at least 65 years (n = 72) and younger controls aged 20 to 50 years (n = 58) with a diagnosis of a unilateral isolated orbital fracture was designed and implemented...

The orbital bones are thin and exposed, making the orbital walls vulnerable to fractures. The floor of the orbit is the weakest portion of this 4-sided pyramid structure. Blunt force trauma is the primary mechanism of injury in young men between the ages of 18 and 30 years. Computerized tomography is the primary imaging technique to diagnose orbital fractures. Conservative versus surgical management is determined by maxillofacial and ophthalmology specialists.

Maxillary sinus mucocele can occur due to many medical factors such as chronic infection, allergic sinonasal disease, trauma, and previous surgery. However, it occurs mainly after Caldwell-Luc operation, usually more than 10 years after surgery. There are a few cases of maxillary sinus mucocele with ocular symptoms. Also, a case causing ocular symptoms because of invasion to the orbital floor is rare. Therefore, we report a case of a 55-year-old male patient who underwent Caldwell-Luc operation about 30 years ago...

PURPOSE: The inferior oblique muscle branch of the oculomotor nerve is susceptible to injury during orbital fat removal from the inferolateral quadrant of the orbit. Understanding the amount of removable orbital fat volume in this quadrant may be helpful in achieving maximum fat decompression without causing nerve injury. The aim of this study was to calculate the orbital fat volume in the inferolateral quadrant using computed tomographic (CT) images. METHODS: In this retrospective, observational study, contiguous 1-mm coronal CT images were obtained from 53 sides (30 patients)...

BACKGROUND: To compare clinical findings of orbital trapdoor fractures between adult and paediatric patients. METHODS: Paediatric patients were categorised into two groups by age: children (0-9 years) and adolescents (10-19 years). Adult patients were categorised into two groups by age: early (20-44 years) and middle-late adulthood (≥45 years). Demographic data, ocular and periocular complications, CT findings and binocular single vision field (BSVF) were compared among age groups...

PURPOSE: To evaluate the aesthetic and functional outcomes of autologous fat transfer using the SEFFI (superficial enhanced fluid fat injection) technique for reconstruction of the periocular area. METHODS: Autologous fat injections prepared with the 0.5 mL and 0.8 mL SEFFI technique were used in four patients for periocular rehabilitation. RESULTS: Case 1 (C1): A patient with left-sided progressive facial hemiatrophy underwent ipsilateral volumizing with 0...

INTRODUCTION: An ectropion is a complication that can arise from reconstruction in the infraorbital region. Often, this complication occurs despite proper positioning of the lower lid at the time of closure. Various transcutaneous approaches to orbit skeleton have investigated in view of complication arising from them. A subtarsal approach with a postoperative Frost suture gives an advantage to reduce the occurrence of ectropion especially after treatment of orbital floor fractures. MATERIAL AND METHODS: This case describes a method of subcuticular suturing technique for subtarsal incision of lower lid which can be used to support the lid during healing period, thus decreasing the rate of ectropion...

BACKGROUND: Resorbable mesh and porous polyethylene are frequently used alloplastic materials for the treatment of the orbital blowout fractures. The literature lacks reports comparing their long-term effects on experimental models. OBJECTIVE: Our aim was to radiologically and histologically evaluate the effectiveness and safety of porous polyethylene and resorbable mesh in a rabbit orbital blowout fracture model. METHODS: Twelve New Zealand white rabbits (24 orbits) were randomized to 4 groups...

We present the case of a woman referred to our department at 34 weeks of pregnancy with a fetal ultrasonographic scan showing a mass that had developed within the right maxilla with invasion of the orbit. A retrospective examination showed that this tumor had been present since the 12th week of pregnancy. At 39+4 weeks of gestation, a boy was born. He presented a black firm aspect in the maxilla. A computed tomographic scan and magnetic resonance imaging revealed a soft tissue swelling over the right maxilla, extending into the orbit but without invasion of the globe...

Bony hyperostosis is commonly associated with meningioma growth and is considered one of the characteristic signs on imaging; however, recurrence of meningiomas in the sphenoorbital area, including associated hyperostosis, is typically precluded by gross total resection of the lesion. This 63-year-old man presented with progressive double vision and proptosis in the right eye. He underwent frontotemporal craniotomy and partial removal after magnetic resonance imaging demonstrated a right sphenoorbital meningioma extending to the orbit and middle fossa...

BACKGROUND AND AIM: The otolaryngologist often meets with fractures of the orbital floor. The most serious complication is diplopia, arising as a result of herniation of the orbital contents, with or without fixation of the inferior rectus muscle. The aim of our work was to create a mathematical model to calculate the volume of prolapsed soft tissue of the orbit in blow-out fractures, as a factor in deciding on the need for surgical treatment. PATIENTS AND METHODS: In a retrospective study (2007-2013), we evaluated 80 patients with blow-out fractures, divided into two equal groups: 40 conservatively treated and 40 surgically treated patients...

Orbital floor fractures can produce acute constitutional symptoms and poor ocular outcomes. This study aims to determine the clinical and radiological predictors of tissue entrapment in pediatric orbital floor fractures and to explore the effect of operative timing on ocular outcomes. The authors reviewed medical records from pediatric patients with orbital floor fractures from 2007 to 2015. One hundred fifty-two patients with 159 orbital floor fractures were included. One hundred twenty-two (80.3%) patients were male, and the mean age was 12...

Computer-aided design/computer-aided manufacturing (CAD/CAM) guides are now widely used in maxillofacial reconstruction. However, there are few reports of CAD/CAM guides being used for scapular flaps. The authors performed the secondary maxillary and orbital floor reconstruction using a free latissimus dorsi muscle, cutaneous tissue, and scapular flap designed using CAD/CAM techniques in a 72-year-old man who had undergone partial maxillectomy four years previously. The patient had diplopia, the vertical dystopia of eye position, and a large oral-nasal-cutaneous fistula...

Backgroung and Aim. This work builds on our publication on the subject of creating a mathematical model for calculating the volume of proplaped soft tissue of the orbit in blow-out fractures, which aids us greatly in our choice of the most effective treatment immediately post-accident. PATIENTS AND METHODS: In this prospective study (2014 - 2016) we treated 29 patients with blow-out fractures. 18 (62%) were treated conservatively and in 11 (38%) we proceeded surgically. We decided whether surgical or non-surgical therapy was appropriate on the basis of clinical ENT, eye examination and the total volume of prolapsed orbital soft tissue...
