Displacement of implant in the maxillary sinus is the common complication occur because of improper evaluation of available bone volume or inadequate osteotomy preparation.
When an implant that lacks sufficient primary stability in the host bone is displaced into the maxillary sinus it should be removed immediately before retrieval becomes more difficult. In addition, if the implant has perforated the sinus membrane it is possible that this could initiate acute maxillary sinusitis. In cases with less than 4 mm of crestal bone support, a staged approach with sinus lift grafting should be performed 4-6 months before a second surgery to place the implants.
Here's an interesting case that you can see their results

I agree with Dr. Sclar. An implant that is displaced into the maxillary sinus should be removed as quickly as possible. The one caveat is that the person who is retrieving this implant must have the requisite skills and experience to do so. If the implant was displaced into the maxillary sinus by a clinician who lacked experience in this lack of experience was the reason for the displacement I would certainly recommend against that individual attempting to retrieve the implant that was mistakenly displaced. Conversely, even in the hands of a clinician who is highly skilled, displacement can occur albeit very rarely. That skilled clinician should be able to retrieve the implant in short order.

Immediate retrieval Of implant from maxillary sinus sure is better then delayed . However this complication should be considered when applying implants to posterior maxill
In agreement with the other comments, implant removal should be done quickly with either intra-oral approach by lateral window or functional endoscopic sinus surgery
(FESS). The attached paper might be of your interest.
