Abstract

BACKGROUND: The sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available.

OBJECTIVE: The purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants.

METHODS: This was a retrospective case series that described nine patients who, between June 2011 and September 2016, underwent endoscopic sinus surgery for CRS after a sinus lift procedure. The presenting symptoms of the patients, medical management, imaging results, operative procedures, and outcomes were reviewed.

RESULTS: The majority of patients developed symptoms (mucopurulent nasal drainage, facial pain and/or pressure, nasal congestion, and foul smell) within 3 months of implant placement and were treated with at least three courses of antibiotics before referral to an otolaryngologist. All the patients underwent wide endoscopic maxillary antrostomy, with no surgical complications or postoperative reports of infection. There was a statistically significant improvement in 22-item Sino-Nasal Outcome Test scores (t(8) = -2.908; p = 0.02) and discharge, inflammation, and polyps/edema endoscopic scores ([z = -2.539; p = 0.011) between pre- and postsurgical treatment. Four patients had their dental implants removed before presentation. Among the five patients who presented with intact dental implants, none required removal before or after functional endoscopic sinus surgery.

CONCLUSION: Functional endoscopic sinus surgery was a reasonable and efficacious treatment option for patients who presented with paranasal sinus disease after a sinus lift. Dental implant removal may not be a requirement for successful treatment of CRS associated with sinus lift procedures.
