Background: For a long time, the hypertrophied tonsils impact on velopharyngeal closure has been a point of
concern.
Objectives: To identify the alterations in the velopharyngeal valve (VPV) closure patterns following
adenotonsillectomy in Arabic-speaking children, to predict the incidence of complications as nasal regurgitation or
open nasality.
Patients and methods: This observational prospective research was performed on 100 patients, with hypertrophied
adenoid and tonsils, who were collected from outpatient clinic of Benha University Hospitals. All cases underwent
preoperative laboratory investigations, otorhinolaryngology examination and video-nasoendoscopy and speech
assessment before and after adenotonsillectomy.
Results: The VP closure pattern was insignificantly different between both groups. However, the Nasality was
significantly different among the 3 studied periods (P
