The associated disruption of palatal structure leads to abnormal velopharyngeal anatomy, frequently resulting in failure to achieve adequate closure of the velopharyngeal valve even after primary palatal repair.\n\nBuccal artery myomucosal flap Firstly described by Bozola this axial-pattern flap is based on and centered around the buccal artery, a branch of the internal maxillary artery. The flap extends from the maxillary tuberosity to the oral commissure and is primarily used for the closure of mucosal defects involving the posterior hard palate, soft palate, and maxillary alveolus.","This study is a prospective comparative and retrospective study designed to evaluate the donor site morbidity and buccinator muscle integrity after buccinator myomucosal flap in patients with velopharyngeal incompetence",[20],{"label":21,"type":13,"description":22,"interventionNames":23},"Buccinator Myomucosal Flap Group","Patients with velopharyngeal incompetence undergoing palatal lengthening using bilateral posteriorly based buccinator myomucosal flaps.",[24],"Procedure: Bilateral posteriorly based buccinator myomucosal flap surgery",[26],{"type":27,"name":28,"description":29,"armGroupLabels":30,"otherNames":13},"PROCEDURE","Bilateral posteriorly based buccinator myomucosal flap surgery","Palatal lengthening will be performed using bilateral posteriorly based buccinator myomucosal flaps in patients with velopharyngeal incompetence.",[21],[32],{"name":33,"role":34,"phone":35,"phoneExt":13,"email":36},"Abdelrahman S Ahmad, MBBCH","CONTACT","00201013858729","abdelrahamn.saleh@med.sohag.edu.eg",[38],{"facility":5,"status":39,"city":40,"state":13,"zip":41,"country":42,"countryCode":43,"cosmosGeoPoint":44,"geoPoint":49,"contacts":50},"RECRUITING","Sohag","82511","Egypt","EG",{"type":45,"coordinates":46},"Point",[47,48],31.69478,26.55695,{"lat":48,"lon":47},[51,53,56,58],{"name":52,"role":34,"phone":35,"phoneExt":13,"email":36},"Abdelrahman S Ahmad, MSc",{"name":54,"role":55,"phone":13,"phoneExt":13,"email":13},"Mostafa M Mohammad, MD","SUB_INVESTIGATOR",{"name":57,"role":55,"phone":13,"phoneExt":13,"email":13},"Ahmed S Mazeed, MD",{"name":59,"role":55,"phone":13,"phoneExt":13,"email":13},"Ahmad M Abd-elmoniem, MD",{"type":61,"investigatorFullName":62,"investigatorTitle":63,"investigatorAffiliation":5,"oldNameTitle":13,"oldOrganization":13},"PRINCIPAL_INVESTIGATOR","Abdelrahman Saleh Ahmad","Resident of Plastic Surgery, Faculty of Medicine, Sohag University, Egypt","100658626","donor-site-morbidity-and-buccinator-muscle-integrity-after-buccinator-myomucosal-flap-surgery-in-patients-with-velopharyngeal-incompetence-100658626",false,"NCT07853872","Donor Site Morbidity and Buccinator Muscle Integrity After Buccinator Myomucosal Flap Surgery in Patients With Velopharyngeal Incompetence","Evaluation of Donor Site Morbidity and Buccinator Muscle Integrity After Buccinator Myomucosal Flap Surgery in Patients With Velopharyngeal Incompetence","Inclusion Criteria:\n\n* Patients diagnosed with velopharyngeal incompetence undergoing palatal lengthening using bilateral posteriorly based buccinator myomucosal flaps.\n* Non-syndromic patients.\n\nExclusion Criteria:\n\n* Syndromic cleft patients with associated neuromuscular disorders.\n* History of previous cheek surgery affecting the buccinator muscle.\n* Patients who declined participation in the study.","ALL","18 Years",{"count":74,"type":75},15,"ESTIMATED","OBSERVATIONAL","The aim of this study is to evaluate donor site morbidity and buccinator muscle integrity following the use of buccinator myomucosa flap in patients with velopharyngeal incompetence.",[79,80,81,82,83,84],"Donor Site","Morbidity","Buccinator Muscle","Integrity","Buccinator Myomucosal Flap Surgery","Velopharyngeal Incompetence","2026-10-04",{"date":87,"type":88},"2026-10-06","ACTUAL",{"date":85,"type":88},{"date":91,"type":75},"2027-03-01",{"name":5,"class":6},1]
