A systematic literature review and a meta-analysis of indirect sinus lift without the use of bone graft material was performed. A PubMed search was made from January 2005 to January 2012 with keywords: "sinus lift", "osteotome", "graft" and "maxillary sinus elevation". The inclusion criteria were: maxillary sinus lift technique with osteotomes with a minimum follow-up period of 5 months after s...

BACKGROUND Maxillary sinus mucoceles are relatively rare among all paranasal sinus mucoceles. With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons prefer transnasal endoscopic management of sinus mucoceles. The aim of this study is to describe the clinical presentation of maxillary sinus mucoceles and to establish the efficacy of endoscopic management of sinus muco...

BACKGROUND AND PURPOSE The infraorbital nerve arises from the maxillary branch of the trigeminal nerve and normally traverses the orbital floor in the infraorbital canal. Sometimes, however, the infraorbital canal protrudes into the maxillary sinus separate from the orbital floor. We systematically studied the prevalence of this variant. MATERIALS AND METHODS We performed a retrospective revi...

Fungus is one of the causes of chronic rhinosinusitis. If the fungus occupies the sinus but does not invade the sinonasal mucosa, this is called sinus fungus ball. Any association between anatomical variations and fungus ball remains unclear. Sinus fungus ball is defined as non-invasive chronic fungal rhinosinusitis occurring in immunocompetent patients, and the maxillary sinus is the most comm...

colleagues in this procedure as the zero degree endoscope was inserted into the nose through the left nostril, and was manipulated past the inferior concha into the middle meatus where the maxillary sinus was entered through the opening emoval of teeth where there is a close communication etween the maxillary sinus and the oral cavity can lead to he root being dislodged into the maxillary sinus...

INTRODUCTION Chronic rhinosinusitis with nasal polyposis is a common chronic disease that often affects maxillary sinus. Endoscopic sinus surgery is the most common procedure for treating the majority of maxillary sinus lesions. OBJECTIVE To demonstrate the role of canine fossa puncture during endoscopic sinus surgery procedure in patients with severe maxillary sinus disease. METHODS We pre...

BACKGROUND Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. CASE REPORT Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery...

INTRODUCTION Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contaminat...

A common dilemma in adult orthodontic treatment is deciding how best to treat missing posterior teeth. One treatment option is to orthodontically close the space. But closure can be difficult, especially if the open space is in the maxillary posterior area, because tooth movement through the maxillary sinus is limited. The increased difficulty of moving teeth in the maxillary sinus is similar t...

Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying membrane. We evaluated the location ...
