In this case report we describe a 27-year-old man who presented with progressive enophthalmos for 5 months without any other associated ocular symptoms such as pain, diplopia, or visual disturbance. Computed tomography showed that his progressive enophthalmos originated from a frontoethmoidal mucocele and this caused destruction of the lamina papyracea and shrinkage of the ethmoidal air cell. F...

Mucoceles are cystic formations lined with respiratory epithelium that contain a mucoid or mucopurulent fluid. Although benign, mucoceles are locally expansive, due to continuous production and accumulation of mucus, resulting in erosion and underlying bone remodeling. This may affect the orbit, skull base, or soft tissue of the face. Frontal, ethmoidal, and fronto-ethmoidal sinuses are the mos...

INTRODUCTION Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. CASE PRESENTATION We described a lateral frontal sinus mucocele w...

The following case illustrates how an orbital tumour may mimic a posterior segment mass on funduscopy by virtue of its indentation of the globe. Imaging techniques are shown to be vital in the elucidation of the true pathology. Case report A 30-year-old woman complained of severe throbbing pain in the right orbital region, associated with lacrimation and nausea, which had been intensifying over...

Frontal sinus mucoceles are benign, pseudocystic lesion deriving from the obliteration of the sinus ostium, resulting in a continuous mucous accumulation. The growing process of a mucocele leads to a progressive enlargement of the sinus cavity, thickening and eroding its bony walls up to invading the surrounding tissues. The surgical procedure through an endoscopic endonasal approach is the cur...

The purpose of this study was to determine the treatment modalities with sinogenic complications. We present a retrospective assessment of 11 patients who developed various types of complications, including an abscess within the temporal bone pyramid, frontal sinus and orbital mucocele, and a subperiosteal abscess with orbital apex syndrome. Three patients have suffered from decreased visual ac...
