The hypoplastic maxillary sinus and the orbital floor.

PURPOSE OF REVIEW: Hypoplastic maxillary sinus is a relatively rare clinical problem that has a variable presentation. The purpose of this article is to review the recent literature with regard to evaluation and treatment. RECENT FINDINGS: Most authors suggest that hypoplastic maxillary sinus results from the development of negative pressure resulting from an obstruction of maxillary sinus ventilation. Patients most frequently present with unilateral enophthalmos but some cases may be identified incidentally on imaging studies. SUMMARY: Hypoplastic maxillary sinus is a rare clinical entity with variable presentation. Evaluation and management are tailored to each individual patient's degree of disease and symptoms.

Orbital inflammation.

Orbital inflammation is a common problem in adults and children, accounting for the majority of all orbital processes. The presentation may be acute, subacute, or insidious. When the onset is acute, the process can be mistaken for orbital cellulitis. In insidious cases, such as the sclerosing subtype of inflammation, the chronic painless course may prompt concerns about a neoplastic infiltration such as lymphoma. Orbital inflammation can be divided into nonspecific, idiopathic, and other specific diagnoses. The differential diagnosis includes allergic, infectious (fungal, mycobacterial, and parasitic), and neoplastic (lymphoma or metastatic) disease. Orbital inflammation impacts neurologists and neuro-ophthalmologists because all of the entities can cause afferent dysfunction (decreased vision, abnormal color perception, afferent pupillary defect, and visual field defect) and dysmotility. The pattern of motility deficit may mimic the more familiar cranial nerve palsies. Advances in the diagnosis and management of nonspecific orbital inflammation and the specific entities that cause orbital inflammation are discussed.
