“…Careful presurgical planning that takes into account the exact structure of the maxillary sinus and possible anatomical variations is essential to avoid perforation of the sinus mucosa. With normal sinus anatomy, preparation and horizontal rotation of a trap door in the maxillary sinus wall is possible, provided that the Schneiderian membrane is sufficiently lifted (ten Bruggenkate and van den Bergh, 1998; van den Bergh et al, 2000;HatanoVan et al, 2004). A septum represents one of the most significant anatomical limitations to the correct positioning of the sinus membrane.…”

“…The internal structure of the maxillary sinus is a critical determinant for complications in certain oral surgical procedures (Ten Bruggenkate and van den Bergh, 1998;Vitkov et al, 2005). Careful presurgical planning that takes into account the exact structure of the maxillary sinus and possible anatomical variations is essential to avoid perforation of the sinus mucosa.…”

“…The presence of anatomic variations within the maxillary sinus, such as septa, has been reported to increase the risk of sinus membrane perforation during the sinus elevation procedure (Tatum, 1986;Betts and Miloro, 1994;Krennmair et al, 1999;Van Den Bergh et al, 2000;Kim et al, 2006). This anatomic variation was first described by Underwood in 1910 and, therefore, has sometimes been referred to as Underwood's septa.…”

“…The convex sinus floor usually reaches its deepest point at the first molar region. Several conical elevations projecting into the sinus floor and corresponding to the roots of the first and second molar teeth sometimes perforate (Van den Bergh et al, 2000;Williams et al, 1995). The loss of teeth causes remodeling and resorption of the surrounding alveolar bone and eventually leads to an atrophic edentulous ridge (Misch, 1999).…”

The anatomical structure of the maxillary sinus is fundamental to maxillofacial surgery. The presence of septa, located at the inner surface of the maxillary sinus, increases the risk of sinus membrane perforation during sinus elevation for dental implant surgery. The aim of this study was to evaluate the anatomy of maxillary sinus septa.Data in this study was obtained from a total of 205 cases. One hundred and seventy-seven patients were partially edentulous (PE) whereas 28 patients had no teeth. Dental computerized tomography (dental CT) was used in the assessment of 410 sinus segments (205 left and 205 right segments). The prevalence of sinus segments with septa was found to be 145/410. Septa were detected in 91 of the 177 PE cases. There were a total of 26 septa in 18 of the 28 completely edentulous (CE) cases. A total of 165 septa were detected in these segments. The prevalence of septa was 46.4% (26/56) in the CE, and 39.2% (139/354) in the PE segments. Thirty septa were found in the anterior, 110 in the middle and 25 in the posterior region. All detected septa were located mediolateral direction. Their relative position: lateral, middle or medial were also noted. The height measurements of the septa varied amongst the different positions. In view of the fact that septa of various heights and courses can develop in all parts of the maxillary sinus, timely and adequate assessment of the inner aspect of the maxillary sinus is essential to avoid complications during sinus augmentation procedures.

“…Since the Alabama implant meeting at Birmingham in 1976, when Tatum 1 introduced a surgical technique involving the maxillary sinus, good results have been reported with this method. [2][3][4] The traditional method involves a trapdoor approach by opening a bony window via a top hinge in the lateral maxillary sinus wall, 5,6 modifying the original technique reported by Tatum. With all the advantages of the original method, there are limitations for the surgical approach into the sinus under poor anatomic conditions, such as a thick lateral maxillary sinus wall or sinus septum in the surgical field.…”
