چکیده
150 Maxillary sinus hypoplasia (MSH) is the underdevelopment of maxillary sinus antrum and it is usually associated with other anomalies, such as uncinate process and infundibular passage. Hypoplasia is classified into three: Type I is mild hypoplasia, normal uncinate and infundibulum; Type II is significant hypoplasia with hypoplastic or absent uncinate and pathological infundibular passage; Type III is cleft-like sinus and absent uncinate1.

CT evidence of mucosal thickening in the maxillary antra in patients with nasopharyngeal carcinoma.
CT scans of the maxillary antra in a group of 51 patients with nasopharyngeal carcinoma were compared with those of a control group of 50 patients. Inflammatory thickening of the antral mucosa was demonstrated in 39 of 42 patients with grade WHO (World Health Organization) 2 and 3 nasopharyngeal carcinoma. Biopsy of the antral mucosa in eight of these patients established inflammation and exclu...
متن کاملTreatment Approach for Maxillary Hypoplasia in Cleft Patients: Class III Elastics with Skeletal Anchorage (Report of Two Cases)
Introduction: Treatment ofcleft lip and palate patients requires a multidisciplinary plan. These patients usually have a hypoplastic maxilla due to the prior surgical scars. Orthognathic surgery to advance the maxilla in these patients is not very efficient; therefore, orthopedic interventions during an appropriate age seems to be essential. Case Report: In this article, two cleft lip and pa...
متن کاملThe role of plain radiographs in the diagnosis of chronic maxillary rhinosinusitis in adults.
BACKGROUND Computed tomography is currently the gold standard for the diagnosis of chronic rhinosinusitis. However, this facility is not readily available in many developing countries. Thus, plain sinus radiography is still widely in use in our practice. OBJECTIVES To assess the diagnostic value of plain radiographs in adult patients with uncomplicated chronic maxillary rhinosinusitis. METH...
متن کاملThe role of transmembrane chloride current in afterdepolarisations in canine ventricular cardiomyocytes.
The physiological role of chloride currents (Icl) in cardiac cells is poorly understood. The aim of the present study was to reveal the role of Icl in the genesis of early and delayed afterdepolarisations (EADs and DADs, respectively). First we identified Icl under action potential voltage clamp conditions as the anthracene-9-carboxylic acid (ANTRA) (0.5 mmol/l)-sensitive current. The ANTRA-sen...
