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 ...

This article is divided into six sections that are related to six commonly used operations for surgery on the maxillary sinus. The authors discuss maxillary sinoscopy, the Caldwell-Luc procedure, extended middle meatus antrostomy, endoscopic maxillary sinus antrostomy, minimally invasive sinus technique, and balloon sinus procedures. In each of these procedures, the authors discuss potential co...

OBJECTIVES/HYPOTHESIS The aim of this study was to evaluate the nature and incidence of long-term maxillary sinus adverse events related to endosseous implant placement with protrusion into the maxillary sinus. STUDY DESIGN Retrospective cohort study. METHODS All patients who underwent placement of endosseous dental implants with clinical evidence of implant penetration into the maxillary s...

INTRODUCTION The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS Three radiologists analyzed 109 cone beam computed tomography (CBCT) images. The Kappa test was used to assess the intra- and inter-rater agreem...

PURPOSE To evaluate the frequency, morphology, and locations of maxillary sinus septa using cone beam computed tomographic (CBCT) imaging of the entire maxillary sinus and to analyze factors influencing the presence or absence of septa. MATERIALS AND METHODS CBCT images of the maxilla taken during a 1-year study period (October 1, 2012, to September 30, 2013) were evaluated for the presence a...

This study measured maxillary sinus volume as an aid in determining the volume of graft bone needed before grafting autogenous bone to the maxillary sinus floor. Maxillary sinus volumes were measured from computerized tomographic images of 38 sinuses using a 3-dimensional reconstruction system. When the sinus-lift procedure was simulated, volumes (mean +/- SD) of the inferior portion of the sin...

Maxillary antrolith is a mineralized mass found very rarely in the maxillary sinus formed by exogenous or endogenous origin [1,2]. These mineralized bodies have been variously described as rhinoliths, antral rhinoliths, antral stones, antral calculi, antroliths, sinoliths, maxillary sinus stones and antrorhinoliths. The maxillary sinus is covered by ciliated pseudostratified columnar epithelium...

This study is aimed at assessing the reliability of morphometric measurements performed on the frontal sinus, nasal septum and maxillary sinus in personal identification using three dimensional Cone Beam Computed Tomography. This study propounds the significance of combined use of all three particularly maxillary sinus and nasal septum pattern in individual identification. This retrospective st...

Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin. Two main surgical app-roaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus tech-niques. However, the treatment is not only surgical removal. We are reporting one case of foreign body like a hand sewing needle entered into ...
