INTRODUCTION Cleft lip and palate are craniofacial anomalies highly prevalent in the overall population. In oral clefts involving the alveolar ridge, variations of number, shape, size and position are observed in maxillary lateral incisors. The objective of this manuscript is to elucidate the embryonic origin of maxillary lateral incisors in order to understand the etiology of these variations....

We report a case of inflammatory pseudotumor in the maxillary sinus of the left side. Inflammatory pseudotumor in the paranasal sinus is very rare. It is difficult to make a diagnosis of inflammatory pseudotumor without a histopathological diagnosis, because it simulates malignant disease clinically. A 65-year-old man was admitted to our hospital because of headache and swelling of the left che...

Objective: To present skeletal class III patient treated with protraction face mask and bonded rapid maxillary expander in order to demonstrate the effects of face mask and bonded rapid maxillary expander on maxillary hypoplasia skeletal class III patient. Materials and methods: The patient was reported with skeletal class III malocclusion. The patient was 11 year 3 month old boy and his treatm...

OBJECTIVE The aim of this study was to analyze tooth movement and arch width changes in maxillary dentition following nonextraction treatment with orthodontic mini-implant (OMI) anchorage in Class II division 1 malocclusions. METHODS Seventeen adult patients diagnosed with Angle's Class II division 1 malocclusion were treated by nonextraction with OMIs as anchorage for distalization of whole ...

Objective: The aim of this study was to evaluate and compare the amount of preoperatively planned surgical movement of the maxilla and postoperatively obtained maxillary repositioning. Materials and Method: Thirty-one patients (16 female and 15 male) were included in this study. Fifteen combined maxillary advancement and impaction, 5 isolated maxillary impaction, and 11 isolated maxillary advan...

In flies, the maxillary palp possesses olfactory sensilla housing olfactory receptor neurons (ORNs), which project to the primary olfactory center, the antennal lobes (ALs). The labellum possesses gustatory sensilla housing gustatory receptor neurons (GRNs), which project to the primary gustatory center, the subesophageal ganglion (SOG). Using an anterograde staining method, we investigated the...

Radiologic maxillary sinusitis is an important risk factor for development of bronchopneumonia in mechanically ventilated patients. Nitric oxide produced within the paranasal sinuses is considered to provide an antibacterial environment and to modulate mucociliary clearance function. We hypothesized that a reduced formation of nitric oxide might contribute to the compromised local host defense ...

PURPOSE The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. MATERIALS AND METHODS Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam com...

AGENESIS OF MAXILLARY LATERAL INCISORS IN ORTHODONTIC PATIENTS AND THE RELATION TO OVERALL TOOTH SIZE Jane Wright, DDS Marquette University, May 2011 The maxillary lateral incisor is the second most frequently missing tooth in the dental arch with clinical management requiring a complex and multidisciplinary treatment approach. It has been suspected that teeth could be smaller in the maxillary ...

The most studied recess of the sphenoid sinus seems to be the lateral one, which is highly variable. Less attention seems to be paid to the maxillary recess, extending anterior, inferior and lateral towards the maxillary sinus. Twenty patients were referred for CT of the paranasal sinuses (axial CT), during a 3-month period. After examining the morphology of the sphenoid sinuses, the authors fo...
