“…( 3 ) found 49 published cases between 2000 and 2013. The intrusion of dental implants into the maxillary sinus as well as the different techniques for the maxillary sinus floor elevation have caused that the number of cases reported are steadily increasing ( 4 - 5 ). The incidence of dental implant displacement into the maxillary sinus should be much higher than the estimated in the literature.…”

Implant migration into the nasal fossa is a rare complication and it requires extraction by anterior rhinoscopy. We report a clinical case of placement of short dental implants, fixed or intruded in the nasal fossa floor, which was aspirated by the patient and spontaneously expelled a few days later. To the best of our knowledge, there have been no reports of spontaneously expulsion through the nasal cavity. Key words: Dental implant, nasal cavity, accidental migration.

“…Depending on when it occurs, implant migration into the maxillary sinus is classified as early or late displacement. Early displacement can happen at the time of surgery due to an incorrect surgical technique ( 3 ), excessive force during implant placement ( 5 ), surgical inexperience ( 9 ), a poor or a lack of primary stability at the time of implant placement ( 3 , 9 ), inadequate bone quality or quantity ( 3 ), autoimmune reaction, or changes in intranasal sinus pressure ( 2 ). Late displacement may occur after implant loading due to early loading ( 9 ), inflammatory reactions that cause peri-implantitis and bone loss or implant overload, among others ( 3 ).…”

In this case, the reason for the displacement was related to micro-movements in the implant caused by the complete removable prosthesis used as a provisional solution.…”

Background The replacement of maxillary posterior teeth often challenges the clinician due to bone resorption after dental exodontia and low bone quality. Currently, attempts are being made to shorten treatment times by placing implants simultaneously to sinus lift procedures in borderline cases, which can lead to complications such as displacement of implants into the maxillary sinus. Clinical Case A 54-year-old patient who was planned for complete rehabilitation of the maxilla through a fixed implant-supported prosthesis on 6 implants. At the level of the 3rd sextant, a sinus lift was performed with a lateral window approach (Caldwell-Luc type) and the simultaneous placement of two implants, one of which migrated into the sinus. The implant was displaced after 4 months when the second stage (uncovering) implant surgery was performed for the connection of the healing abutments. The implant was removed a week after the migration, since it had moved to the tuberosity area in the sinus and the lateral window had been performed in a more mesial position, so the patient was recommended to sleep on the right side to achieve the displacement of the implant to a more favourable area, removing it after a week through the same approach. Discussion Surgical strategies for the removal of a migrated implant are essentially divided into two main approaches: endoscopic transoral and endoscopic transnasal (and combined). Conclusions In case of intra-operative migration of the implant into the sinus, it is recommended to remove it as soon as possible to avoid a possible sinus pathology of iatrogenic origin. Key words: Dental implant complications, dental implant, dental implant displacement, maxillary sinus, case report.

“…Visualizing the MS floor and anterior wall has a pivotal role in several sinonasal conditions, among which it is worth mentioning antrochoanal polyps, especially in the pediatric population, recalcitrant MS infections, often of fungal origin, and complications of dental procedures such as fixture dislocation and maxillary sinus grafting failures. In all these settings some authors advocate the use of IA in selected cases, often coupled with traditional MA, 5,[20][21][22] with generally optimal, albeit nonsystematic, results, in small case series.

“…Straight, 45 and 90 nasal forceps, straight and curved probes and elevator and small-tipped mildly-curved suction tips can be inserted and rotated 360 (thus allowing reaching all the fixtures in the specimens), while extremely curved instruments can be easily inserted through the window but with limited rotation. Nevertheless, as it already happened for other in vivo proposals of IA, 5,[20][21][22] we still have to systematically assess which surgical and clinical results we might yield combining our modified IA with other endoscopic accesses. Last, at present we have only minimal in vivo data on the window size obtainable in the pediatric population.…”

Background While middle antrostomy (MA) is the most common approach to the maxillary sinus (MS), it is known for not allowing to fully inspect the whole MS, especially in its inferior and anterior portions. To overcome this limitation, alternative approaches have been proposed, such as inferior antrotomy (IA) and canine fossa accesses (CFA). Objective Given the lack of studies on the MS floor visualization with different accesses, our study aims, in a cadaver lab setting, to systematically compare three different approaches (MA, IA and CFA) in these regards. Methods Eight cadaver heads, previously submitted to CTscan, were prepared inserting fixtures corresponding to teeth 2, 4, 6, 11, 13 and 15 and into the canine fossae. Three approaches were prepared: a wide MA, an IM and a CFA. We endoscopically evaluated, for each specimen, side, access type and scope angle (0°, 30°, 45°, and 70°), which fixtures were visible on the maxillary sinus floor and whether the canine fossa fixture was visible (MA and IA only). Results IA allowed to visualize all fixtures in nearly all cases (14/16 with 70° endoscope), while MA showed poor visualization results (3/16 with 70° endoscope); CFA failed to gain full visualization in most specimens (7/16 with 70°endoscope). Such difference was statistically significant. MA proved unable to visualize the canine fossa fixture in most cases while IA showed excellent possibilities. All differences were statistically significant (p < .001, Mcnemar’s test). Conclusions Our data show that the IA grants a statistically significant superior surgical field vision when compared to MA and CFA, though in vivo validation of these results is still required.
