Impact of orthognathic surgery on voice and speech: a systematic review and meta-analysis

CONCLUSIONS: Orthognathic surgery may have little or no impact on vocal characteristics during vowel production. However, due to the confounding factors involved, estimates are inconclusive. The most prevalent articulatory disorders in the preoperative period were distortion of the fricative phonemes/s/ and/z/. However, further studies must be carried out to ensure greater robustness to these findings.REGISTRATION: PROSPERO (CRD42022291113).PMID:37467104 | DOI:10.1093/ejo/cjad025
