%X <B>UNASSIGNED: </B>Patients with empty nose syndrome usually suffer from paradoxical nasal congestion, nasal dryness, epistaxis and suffocation. Conservative management is general option for the empty nose syndrome. However, there are several patients who continually complain of symptoms. If symptoms persist, surgical options are considered. Therefore, we reviewed surgical and regenerative treatment options of empty nose syndrome.<BR><B>UNASSIGNED: </B>PubMed, Embase, Scopus, Cochrane Register of Controlled Trials, and Google Scholar were searched from the earliest date provided in the database until December 2022. In the studies, treatment outcomes were measured by patient symptom scores such as Sino-Nasal Outcome Test (SNOT-20, 22, and 25), and Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) along with various clinical examiniations.<BR><B>UNASSIGNED: </B>Twenty-eight studies were analyzed. Submucosal injectable materials, allografts/xenografts/cadaveric implants, autologous implants, and synthetic implants were used. Among them, polyethylene implant was most commonly used (23.3%), followed by autologous, homologous, or cadaveric costal cartilage (20%). The most common administration site was the anterior-inferior lateral nasal wall. Most of the studies showed that surgical intervention brought significant improvements in clinical findings including endoscopic exam, acoustic rhinometry, and CT, as well as patients reporting nasal symptom-, psychological-, or overall health-related quality of life questionnaires. However, several studies did not confirm improvement effects in some psychological-related questionnaires or saccharin transit time. The average follow-up duration was 12.0 (2.0-27.6) months. Postoperative adverse effects were reported in only two studies.<BR><B>UNASSIGNED: </B>Several surgical options and recent tissue regeneration techniques have shown its positive efficacy in treating empty nose syndrome. However more detailed investigations with a larger number and a randomized control study are needed to establish a standardized protocol in treating empty nose syndrome patients.
