Santosh G Honavar, Fairooz P Manjandavida, Vijay Anand P Reddy
Orbital extension is a major cause of death in children with retinoblastoma in the developing countries. Delayed detection and inappropriate management contribute to poor outcome. Conventional treatment including primary orbital exenteration or chemotherapy or radiotherapy alone result in mortality as high as 70%. The recent understanding on the role of sequential multimodal therapy with a combination of high-dose chemotherapy, followed by appropriate surgery, radiotherapy, and additional adjuvant chemotherapy has helped dramatically improve life salvage...

BACKGROUND: Sunken upper eyelid is a commonly found deformity among Asians, mostly due to the aging process and excessive orbital fat removal during oriental blepharoplasty procedures. This deformity is frequently accompanied by multiple, poorly defined upper eyelid folds and blepharoptosis. To date, autologous fat graft has been the treatment of choice for this group of patients. However, accurate placement of the graft in the orbital fat is quite challenging, and it can result in contour irregularities when injected into the preseptal plane...

Most boney and cartilaginous lesions of the orbit and periorbital compartments are benign, grow endophytically, and are composed of dense lamellar bone (eburnated or ivory osteomas). An 87-year-old woman had a well-circumscribed, firm, round, and exophytic lesion of the brow region for at least 15 years. Excisional surgery disclosed an osteocartilaginous lesion with an enveloping pseudocapsule (periosteum/perichondrium) and a narrow stalk connecting it to the frontal bone. The periphery of the lesion displayed lamellar bone which appeared to be replacing a central cartilaginous zone...

Thyroid-associated ophthalmopathy (TAO) is a common autoimmune syndrome affecting the thyroid and orbit. It can result in the fibrosis of extraoular muscles and hyperplasia of adipose tissue. The mechanism of TAO is not clear and there was few effective treatment. Recently, orbital decompression was performed on more and more patients. The surgery can improve the appearance of the patient and relieve the symptoms caused by the high orbital pressure. Therefore, it is necessary to re-evaluate the clinical value of the orbital decompression and surgical indications...

INTRODUCTION: Petrositis is a rare but severe complication of acute otitis media and mastoiditis. Despite efficient antibiotic therapy, there are still reports of both intratemporal and intracranial complications of otitis media with the potential risk of high morbidity and mortality. Petrositis has traditionally been treated with surgery, but recent advances in imaging, with improved antibiotic treatment, allow more conservative management. CASE REPORT: In this case report we describe the clinical course and treatment of a 33-year-old man with petrous apicitis who presented with severe otalgia, retro-orbital pain, and sixth cranial nerve palsy Gradenigo syndrome...
