Surgical outcome for empty nose syndrome: Impact of implantation site

Endonasal submucosal implantation has been confirmed to be beneficial for patients with empty nose syndrome (ENS). However, the optimal implantation site has not been defined. This study aimed to evaluate whether lateral nasal wall implantation is superior to inferior nasal wall implantation in terms of clinical benefits and improvements in quality of life.

Retrospective study in a tertiary medical center.

Consecutive ENS patients between 2010 and 2015 with operative histories of inferior turbinectomies and indicated for surgical implantation were enrolled, with at least 1-year follow-up. Patients were divided into lateral and inferior nasal wall groups. SinoNasal Outcome Test (SNOT)-22, Beck Depression Inventory (BDI)-II, and Beck Anxiety Inventory (BAI) were applied before and 1 year after implantation.

Of the total 30 ENS patients analyzed, 14 were in the inferior nasal wall group and 16 were in the lateral nasal wall group. There were no significant intergroup differences in demographic data and preoperative SNOT-22, BDI-II, and BAI scores. Postoperative assessment revealed that the lateral nasal wall group had significantly better SNOT-22 score improvements than the inferior nasal wall group, particularly regarding rhinological symptoms and sleep function.

Lateral nasal wall implantation may provide significantly better clinical outcomes than inferior nasal wall implantation, and thus may be the preferred, more optimal site for implant placement in ENS patients.
