Sinus Lift Complication after using Summer’s Ostetome Technique?
Dr. B. asks:
2 months ago I placed an implant in #14 area using a drill to prepare the osteotomy and Summer’s osteotome technique on the apical 3mm to raise the sinus floor. The procedure was uneventful and the area is healing very well. However the patient had emetic episodes on the night of the procedure and has been experiencing vertigo and light headedness since the procedure was performed especially when tilting her head backwards. Anybody have an idea what is going on here? Is any further treatment indicated at this time?

Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder and occurs due to head motion resulting in temporary vertigo. There are two main hypotheses to explain the development of BPPV.First, the cupulolithiasis theory, which is based on the attachment of otolithic debris to the cupula in crista ampullaris and the theory of canalithiasis, which is based on free-floating debris in the canal.There are always some debris or particles present in posterior semicircular canal. The presence of vertical upbeating and rotatory-type nystagmus toward the lower ear and the nystagmus developing in the opposite direction along with the occurrence of vertigo when brought back to sitting position confirm the diagnosis.A horizontal variant of BPPV was has also been reported on patients with positional vertigo and horizontal direction-changing positional nystagmus. The symptoms can be produced by rolling the head while the patient lies in a supine position.The treatment consists of canalith repositioning maneuvers appropriate for the semicircular canal involved.The problem with the above mentioned patient is the sustained vertigo for about two months.In those cases that the SOMMER’s osteotome technique has been used to elevate the maxillary sinus floor followed by some CNS signs or symptoms, it is prudent to check the patient for Battle’s sign, CSF otorrhea, radiographic detection of linear midface fractures and even the Caloric Test.
