The effect of maxillary advancement on articulation of alveolar consonants in cleft patients

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Le Fort I Osteotomy in Cleft Patients: Maxillary Advancement and Articulation

“…The method of speech evaluation is described in more detail in our other paper. 12 Articulation of the sounds /s/, /l/, and /r/ was evaluated using 30 separate words, 7 sentences, and a reading sample. The Finnish naming test originally designed for the Scandcleft project 26 was used when evaluating separate words.…”

“…27 The perceptual re-evaluations completed by 2 speech pathologists were compared against each other with Kappa statistics, and the intra-and inter-rater reliabilities were calculated and found to vary between good and excellent agreement (0.766-0.792 and 0.640-0.651, respectively). 12…”

“…It is well documented that maxillary advancement may have a positive effect on articulation in patients with clefts, 8–12 whereas velopharyngeal function can be adversely affected 8–10,13,14,15,16–20 . The articulation may improve as the malocclusion and the relationship between the lips and upper and lower teeth are normalized.…”

The Relationship Between Maxillary Growth and Speech in Children With a Unilateral Cleft Lip and Palate at 5 Years of Age

“…In addition, there may be intrinsic maxillary growth disturbance associated with cleft palates as patients with an unoperated cleft palate have been noted to have poorer maxillary growth when compared to noncleft cohorts (Ye et al, 2013;Shi & Losee et al, 2015). Children with a cleft palate are, therefore, known to be at risk of developing maxillary hypoplasia and subsequent retrusion, which results in malocclusion and malalignment of the jaws, lips, and tongue (Hagberg et al, 2019;Alaluusua et al, 2020).…”

“…Approximately 25% of young adults with a cleft palate may require orthognathic surgery for maxillary retrognathia after completion of skeletal growth (Woo, 2017). Maxillary advancement has been associated with deterioration in velopharyngeal function (Chanchareonsook et al, 2006;Fitzgerald & Smyth, 2019), but paradoxically, the improvement in the occlusal relationship of the jaws may improve articulation (Pereira et al, 2013;Hagberg et al, 2019;Alaluusua et al, 2020).…”
