Abstract
ObjectiveThis study aimed to evaluate the dimensions of pharyngeal airways among nonsyndromic cleft lip and palate (CLP) patients, comparing them with a healthy control group.DesignSystematic review and meta-analysis.Patients and ExposuresPatients with CLP.ComparisonPatients without CLP.Main Outcome MeasuresPrimary outcomes included the volume of different pharyngeal sections, total pharyngeal airway volume, and the minimum cross-sectional area of the pharynx. Secondary outcomes were to assess the effect of cleft type, age, and sex on pharyngeal airways.ResultsA comprehensive search of MEDLINE, Web of Science, EMBASE, Scopus, and Cochrane's CENTRAL (up to August 2023) identified 39 clinical studies meeting PECO criteria, with their risk of bias assessed using the Risk of Bias in Non-randomized Studies of Exposure tool. Of these, 33 were included in a random-effects inverse variance meta-analysis. The results indicated that nonsyndromic CLP patients demonstrated a significant reduction in the volumes of total pharyngeal airway (P = .01), velopharynx (P < .001), and oropharynx (P < .001) compared to healthy individuals. No significant differences were observed between groups regarding nasopharynx (P = .60) and hypopharynx (P = .36) regions. The minimum cross-sectional area was significantly smaller in CLP patients compared to healthy individuals (P = .02). The cleft type, age, and sex showed no significant effects on the extent of dimension reduction in pharyngeal airways (P > .05).ConclusionThe pharyngeal airway dimensions, particularly in the middle sections (velopharynx and oropharynx), are significantly reduced in nonsyndromic CLP patients when compared to the healthy controls. Variations in CLP type, patient age, and sex do not significantly influence this decrease in dimensions.
期刊介绍：
The Cleft Palate-Craniofacial Journal (CPCJ) is the premiere peer-reviewed, interdisciplinary, international journal dedicated to current research on etiology, prevention, diagnosis, and treatment in all areas pertaining to craniofacial anomalies. CPCJ reports on basic science and clinical research aimed at better elucidating the pathogenesis, pathology, and optimal methods of treatment of cleft and craniofacial anomalies. The journal strives to foster communication and cooperation among professionals from all specialties.
