Electrostimulation resulted in initial improvement but failed to offer long-term benefits. Nasal muscle exercises as a standalone treatment were not found to provide significant subjective improvement. Notably, the addition of electrostimulation to therapy with biofeedback and muscle exercises did not significantly improve nasal valve obstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Preliminary evidence suggests that there is insufficient high-quality data to support nasal muscle strengthening therapies, including biofeedback training, as effective treatments for nasal valve collapse. While uncontrolled studies report subjective and objective improvements, the highest level of evidence did not demonstrate statistically significant benefit. The limited and heterogeneous literature, along with potential publication bias, underscores the need for further well-designed studies to clarify efficacy and long-term outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/01455613261451133","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T13:51:26Z","timestamp":1778507486000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficacy of Nasal Myofunctional Therapy in Nasal Valve Collapse: A Review"],"prefix":"10.1177","author":[{"given":"Jordan Kai","family":"Simmons","sequence":"first","affiliation":[{"name":"Cedars-Sinai Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sai","family":"Reddy","sequence":"additional","affiliation":[{"name":"Temple University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2194-8488","authenticated-orcid":false,"given":"Wasiq","family":"Nadeem","sequence":"additional","affiliation":[{"name":"Keck School of Medicine University of Southern California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaitlynne","family":"Pak","sequence":"additional","affiliation":[{"name":"Cedars-Sinai Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry H.","family":"Chen","sequence":"additional","affiliation":[{"name":"Cedars-Sinai Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew K.","family":"Lee","sequence":"additional","affiliation":[{"name":"Cedars-Sinai Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/014556131809700615"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2018.05.009"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200302000-00033"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-198882010-00010"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00179951"},{"issue":"3","key":"e_1_3_3_7_2","first-page":"145","article-title":"Muscle-building therapy in treatment of nasal valve collapse","volume":"42","author":"Vaiman M","year":"2004","unstructured":"Vaiman M, Eviatar E, Segal S.
