IMPORTANCE Noncongenital immature teratomas in the head and neck are extremely rare, and to our knowledge have not previously been reported in the maxillary sinus of a pediatric patient. OBSERVATIONS Teratomas are neoplasms that contain tissue from more than 1 embryonic cell layer that is foreign to the location where they arise and are most commonly found in the sacrococcygeal and gonadal re...

introduction a mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. mucopyocele is an infected mucocele. case report we presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. computed tomography scan showed opacification of the left maxillary sinus expanding thr...

Introduction. An antrolith is a calcified mass within the maxillary sinus. The origin of the nidus of calcification may be extrinsic (foreign body in sinus) or intrinsic (stagnant mucus and fungal ball). Most antroliths are small and asymptomatic. Larger ones may present as sinusitis with symptoms like pain and discharge. Case Report. We report a case of a 47-year-old lady who presented with he...

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

Calcifying epithelial odontogenic tumors are benign odontogenic neoplasms whose occurrence in the maxillary sinus is rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures. We report a case of a large calcifying epithelial odontogenic tumor of the maxilla, involving the maxillary sinus in a 48-year-old woman. The tumor was largely intraosse...

the silent sinus syndrome (sss) involves painless facial asymmetry and enophthalmos, which is theresult of chronic maxillary sinus atelectasis. in most cases, it is diagnosed clinically, however, usingthe characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification,and sinus volume loss caused by inward retraction of the sinus walls. obstruction of the maxil...

Introduction: Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate...

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...
