Silent sinus syndrome: a case presentation and comprehensive review of all 84 reported cases.

Objectives: The term silent sinus syndrome has been used to describe the constellation of progressive enophthalmos and hypoglobus due to gradual collapse of the orbital floor with opacification of the maxillary sinus, in the presence of subclinical chronic maxillary sinusitis. Currently, it is believed to occur as a result of the sequence of events following maxillary sinus hypoventilation due to the obstruction of the ostiomeatal complex.

Methods: In this study, we present a case of true silent sinus syndrome.

Cutaneous mucormycosis of the head and neck with parotid gland involvement: first report of a case.

Cutaneous mucormycosis is an uncommon, life-threatening, opportunistic fungal infection that is a distinctly different entity from the more frequent although still uncommon rhinocerebral form that is better known to otolaryngologists. We describe what to our knowledge is the only reported case of cutaneous mucormycosis of the face with parotid gland involvement, which occurred in a 56-year-old man. The diagnosis was established by tissue biopsy.
