RESUMO
BACKGROUND: Measurements of postoperative velopharyngeal dysfunction (VPD) can be used to determine the efficacy of a palatoplasty operation. Hypernasality and audible nasal air emission are typical manifestations of VPD during speech. We aimed to longitudinally compare VPD outcomes in postpalatoplasty patients who underwent Furlow repair versus straight line repair with intravelar veloplasty (IVVP). Additionally, we examined the relationship between VPD outcomes and select pre-existing patient characteristics. METHODS: Retrospective chart review was performed to identify primary palatoplasty patients treated from April 2012 to March 2021. Variables collected included gender, syndromic status, primary language, Veau cleft type, type of speech assessment, age at time of surgery, degree of hypernasality, presence of audible nasal air emission, and overall adequacy of velopharyngeal function. Pearson χ2 test and multivariable t tests were used to analyze variables. Logistic regression was used to control for statistically significant variables. RESULTS: Of the 118 patients included, 38 received a Furlow procedure and 80 received a straight line with IVVP procedure. Audible nasal air emission was present in 57.3% of straight line with IVVP patients and 42.9% of Furlow patients, with no statistically significant difference between groups. Clinically significant hypernasality was present in 42.1% of straight line with IVVP patients and 22.9% of Furlow patients (P=0.05). Velopharyngeal function was classified as adequate in 63.5% of straight line with IVVP patients and 83.3% of Furlow patients (P=0.03). However, after stratifying by syndromic versus nonsyndromic status, there was no statistically significant difference between straight line with IVVP and Furlow patients for postoperative hypernasality and velopharyngeal function. CONCLUSIONS: This study suggests that there are no statistically significant differences between straight line with IVVP and Furlow palatoplasty techniques regarding speech outcomes including hypernasality, audible nasal air emission, and overall VP function. Furthermore, select patient characteristics such as gender, primary language, syndromic status, age at repair, and Veau cleft type do not significantly impact postoperative speech outcomes.
RESUMO
BACKGROUND: Velopharyngeal insufficiency (VPI) results from incomplete closure of the velopharyngeal (VP) sphincter with oral pressure consonants during speech. Maxillary hypoplasia is common among cleft children and often requires LeFort I advancement. This results in anterior movement of the soft palate with the bony maxillary segment. Consequently, the size of the VP sphincter is increased and may result postoperative VPI or worsening of prior VPI. To better counsel our patients and their families of the risk of VPI after LeFort I advancement, we chose to evaluate our own cohort. METHODS: We conducted an institutional review board-approved prospective review of all cleft children presenting to Texas Children's Hospital who underwent LeFort I advancement after previous palatoplasty between 2013 and 2016 in a three-surgeon, consecutive patient series. Data collected included age, sex, ethnicity, cleft type, prior secondary speech surgery, presence of preoperative fistula, planned distance of advancement, orthognathic surgery performed, and any concurrent procedures performed. Primary outcomes measured included preoperative and postoperative VP function and hypernasality as measured by a certified speech pathologist. RESULTS: Velopharyngeal function was unchanged in 67% of our cohort after LeFort I advancement. Of those patients, 83% had evidence of VPI preoperatively, and 17% had normal speech preoperatively. Twenty-two percent of the patients displayed worsening VP function after surgery, and 6% displayed evidence of improvement. Velopharyngeal function was unable to be assessed in 6% of patients. Nasality ratings worsened in 39% of patients, were unchanged in 39%, and improved in 22%. Of the patients with incompetent VP function after surgery, 50% already received or are currently scheduled for secondary speech surgery, 25% declined secondary surgery, and 25% are pending scheduling. CONCLUSIONS: Although VP function remains unchanged in a majority of patients after LeFort I advancement, VPI should be carefully screened for after surgery. If detected, secondary operations to correct speech should be strongly considered.
