The purpose of this study was to analyze the treatment and posttreatment maxillary changes achieved with maxillary protraction therapy. The cephalometric records of 25 consecutively treated Chinese children with Class III malocclusions (mean age 8.4 years) were analyzed for cephalometric A point changes, which were then compared with an untreated, age and sex matched Class III control sample. A...

The maxillary sinus haematoma is an uncommon cause of a maxillary sinus mass. It presents with a variety of symptoms, the most common being epistaxis. Although histologically benign, it may be clinically progressive. Radiological findings can range from a benign appearance to a more aggressive process, including bony erosion. Surgical evacuation is the mainstay of therapy. We describe our exper...

Maxillary sinus foreign bodies are commonly due to penetrating trauma and iatrogenic events. A foreign body is usually identified during initial assessment and subsequently removed. We present a rare method of maxillary sinus trauma with retained and subsequent discharged foreign body twelve years following the initial injury.

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

PURPOSE The purpose of this retrospective study was to compare the performance of cone-beam computed tomography (CBCT) and panoramic radiography in detecting the presence and location of maxillary sinus septa. MATERIALS AND METHODS This study included radiographic examination of 104 maxillary sinuses of 52 individuals (26 females, 50% and 26 males, 50%) whose panoramic radiographs and CBCT im...

PURPOSE This study investigated the relationship between the roots of the maxillary molars and the maxillary sinus using cone beam computed tomography (CBCT), and measured the distances between the roots of the maxillary molars and the sinus floor as well as the thickness of the bone between the root and the alveolar cortical plate. MATERIALS AND METHODS The study sample consisted of 83 patie...

The maxillary permanent canine acts as the corner stone of occlusion and plays a key role in smile design. Any morphological defect or eruption anomaly, affecting the maxillary permanent canine has a negative impact on the smile and facial esthetics of the person. The etiology of impacted maxillary permanent canine is multifactorial. Maxillary transverse discrepancies have been reported in 7 – ...
