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...

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...

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 ...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

Few studies have compared the relationship of MSV in different craniofacial patterns. Hence, purpose this research was to evaluate maxillary sinus volume patterns using cone-beam computed tomography. This cross-sectional study included 100 pre-orthodontic patients mean aged 26.40 ± 6.77 (age ranged 21–64) years divided into anteroposterior and vertical skeletal groups. From cone beam tomography...

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...
