The maxillary sinus augmentation procedure has been gaining more acceptance among dental professionals. The aim of this review article is to provide an update about various aspects of anatomy, physiology, and common pathological conditions of the maxillary sinus and their clinical relevance to the sinus augmentation procedure and subsequent implant placement.

Enophthalmos developed in a 44-year-old woman with history of respiratory infection but not of sinus disease. Sinus roentgenograms and MR revealed opacification of the right maxillary antrum, deviation of the nasal septum to the right, obstruction of the right osteomeatal complex, and diminished volume of the right maxillary sinus.

150 Maxillary sinus hypoplasia (MSH) is the underdevelopment of maxillary sinus antrum and it is usually associated with other anomalies, such as uncinate process and infundibular passage. Hypoplasia is classified into three: Type I is mild hypoplasia, normal uncinate and infundibulum; Type II is significant hypoplasia with hypoplastic or absent uncinate and pathological infundibular passage; T...

A very low incidence of complications of rehabilitating jaw with implant therapy ismigration of dental implants into maxillary sinus. Implant migration into the maxillary sinus may be followed by sign of infection and oroantral communication. This way, paranasal sinus function will be appearing altered after the implant migration and hence implant removal is utmost important.

Endosseous implants are frequently used for prosthetic reconstruction in the edentulous patient. Sufficient volume and density of the alveolar bone for implant integration and load bearing are prerequisites for good clinical outcome. Bone resorption following the extraction of posterior maxillary teeth sometimes results in severe loss of bone in vertical and ⁄ or horizontal dimensions, which ma...

We have previously shown that unilateral nasal challenge with antigen causes an increase in the number of eosinophils in the ipsilateral maxillary sinus. Here we aimed to determine whether there was an eosinophil response in the contralateral maxillary sinus after unilateral nasal challenge with antigen. Twenty subjects with a history of seasonal allergic rhinitis and a positive nasal challenge...

adenoid cystic carcinoma is an uncommon, slow growing malignant salivary gland tumor that is characterized by wide local infiltration, perineural spread, propensity to local recurrence anddistant metastasis. in this paper, the authors present a case of adenoid cystic carcinoma affecting the palate and involving the maxillary sinus in a 60‑year‑old male patient along with a brief reviewof litera...

Ectopic eruption into the dental environment is common, whereas eruption into other sites is rare. Diverse anatomical locations such as the mandibular condyle, coronoid process, palate, maxillary sinuses and nasal cavity can infrequently be the site of ectopic tooth eruption. One of the nondental sites for ectopic eruption is the maxillary sinus. Here, we present a case of dentigerous cyst with...

OBJECTIVE The objective of this study is to present patients with sinus augmentation in the presence of an antral pseudocyst and the surgical procedure, complications, and outcome. STUDY DESIGN From 2002 to 2005, 109 patients were scheduled for 1- or 2-stage maxillary sinus floor augmentation (n = 129) because of inadequate alveolar bone height for implant placement. Radiographically, a signi...

A technique, the "Loma Linda pouch," is introduced for repairing the perforated maxillary sinus membrane during sinus grafting procedures. A collagen membrane is placed against the perforated site and subsequently covers the internal surface of the maxillary sinus. The collagen membrane is then folded along the lateral access window to form a pouch that surrounds and isolates the graft material.
