“…The last search was conducted on July, 21st of 2008. Eleven papers published and indexed in MedlinePubMed, assessing presence of antral septa were found (2,3,(5)(6)(7)(8)(9)(10)(11)(12)(13). Septa origin: Classification According to Underwood (5), the maxillary sinus floor is frequently divided into three basins: a small anterior one over the premolar region; a large median one descending between the roots of the first and second molars, and a small posterior one corresponding to the third molar region.…”

This review analyzes articles published on the presence of septa in maxillary sinuses. An automated search was conducted on PubMed using different key words. This search resulted in 11 papers in which the presence of antral septa was assessed. These septa are barriers of cortical bone that arise from the floor or from the walls of the sinus and may even divide the sinus into two or more cavities. They may originate during maxillary development and tooth growth, in which case they are known as primary septa; or they may be acquired structures resulting from the pneumatization of maxillary sinus after tooth loss, in which case they are called secondary septa. Several methods have been used in their study, direct observation on dried skulls or during sinus lift procedures; and radiographic observation using panoramic radiographs or computed tomographs. Between 13 and 35.3% of maxillary sinuses have septa. They can be located in any region of the maxillary sinus and their size can vary between 2.5 and 12.7 mm in mean length. Some authors have reported a higher prevalence of septa in atrophic edentulous areas than in non-atrophic ones. If a sinus lift is conducted in the presence of maxillary sinus septa, it may be necessary to modify the design of the lateral window in order to avoid fracturing the septa.

“…The presence of anatomic variations within the maxillary sinus, such as septa, have been reported to increase the risk of sinus membrane perforation during sinus elevation procedures (1)(2)(3)(4). Maxillary sinus septa were first described by Underwood in 1910 (5).…”

Summary: Maxillary sinus septa and bony bridges were observed using dry skulls in childhood, classified based on Hellman's dental age, to clarify maxillary sinus septum formation.Eighty-eight maxillary sinuses of 44 dry skulls and a cone-beam computed tomography (CBCT) unit were used. The locations of the septum, defined as a pointed bony structure originating from the inferior wall, and bony bridge, defined as a bony structure between the maxillary sinus wall and dental germ, were antero-posteriorly recorded, and the superoinferior distance, distance from the bony palate, and angle to the median palatine suture were measured.The rate of septum presence in the maxillary sinus was high (41.7%) in IIIC, and the septa were located in the deciduous molars, premolars, and molars. Also, all bony bridges were related to the median maxillary sinus wall, and the rate of the maxillary sinus showing a bony bridge was high in IIA and IIIA.

Introduction: Bone atrophy and pneumatization of the maxillary sinus resulting from tooth loss, associated with low bone density in the region, often provide inadequate quantity and quality for the installation of osseointegrated implants. Aim: In the present work, a literary review was carried out to identify and compare the main techniques of maxillary sinus surgery, commenting on the available graft materials. Methodology: A bibliographic search was carried out in the main PUBMED databases, in which works were published that were published from 1955 to 2017. 86 articles met the criteria for inclusion laboratory studies, case reports and systematic reviews as well as literature that were developed In the human species; In which they had done the lifting of the maxillary sinus with allocation of the grafting material. Results: In view of a careful research and tabulations of the respective articles, the result was that in many cases it is necessary to perform a surgical procedure to increase bone height, called maxillary sinus lift. The two techniques used for this purpose are the traumatic technique and the atraumatic technique, with or without bone graft. Conclusion: Maxillary sinus lift is a safe, reliable and successful surgical procedure, provided that the fundamental principles of the technique are strictly adhered to. The risks involved are small, with possible post-operative complications amenable to treatment through medication and / or surgical interventions.
