MRI Assessment of Velopharyngeal Anatomy After Modified Furlow-Buccinator Flap in Late Primary Palate Repair

April 5, 2026 updated by: Dina Adel, Cairo University

MRI Assessment of Velopharyngeal Anatomy in Late Primary Cleft Palate Repair Using Modified Furlow With Buccinator Myomucosal Flap: A Case Series Study

The goal of this case series study is to learn if magnetic resonance imaging (MRI) can show how well the palate and throat muscles work at rest and during speech after late cleft palate repair. The surgery uses a technique in which the muscle from the cheek is used to close the gap and repair the cleft and therefore improve speech. The study will answer the question of whether this technique will provide better closure and improved speech in the participants who have not received early treatment. The participants will have the surgery and then have MRI scans 6 months after surgery while resting and speaking specific sounds. Complete speech assessments will also be done 6 months after surgery.

Study Overview

Detailed Description

This study will include about 10 children, age 5 years and older, with cleft palate who have not had previous palate surgery. All participants will have surgery using the modified Furlow palatoplasty with a buccinator myomucosal flap. This method is designed to improve muscle function and speech outcomes in children who have late cleft palate repair.

Six months after surgery, participants will have MRI scans. The scans will take pictures of the palate and throat muscles while resting and while saying sounds such as "EEE" and "SSS." These images will help researchers see how well the muscles close the gap between the nose and mouth during speech.

Participants will also have a speech evaluation six months after surgery. This will include articulation tests and scoring of speech clarity and nasal resonance.

The study will take place at Cairo University and New Giza University Hospital. By combining MRI results with speech assessments, researchers aim to show whether MRI is a useful tool for evaluating muscle function after this type of cleft palate repair. The findings may help guide future treatment for children who cannot have early surgery.

Intervention / Treatment
Experimental: Cleft palate group
Patients undergoing late primary cleft palate repair with Modified Furlow Palatoplasty combined with buccinator myomucosal flap
The procedure is performed under general anesthesia. After marking a palatal Z-plasty and infiltrating local anesthetic, the parotid duct and buccinator flap donor site are identified. On the left side, a posteriorly based oral myomucosal flap and an anteriorly based nasal flap are created by incising from the uvula to the hard-soft palate junction and laterally toward the hamulus. The levator muscle is fully detached. A small anteriorly based nasal flap is added. On the right side, an anteriorly based oral flap and a posteriorly based nasal myomucosal flap are raised with complete muscle disinsertion. The nasal Z-plasty is interdigitated and sutured, and the oral Z-plasty is closed with minimal muscle overlap. The remaining defect is filled with a right buccal myomucosal flap, which is elevated, tunneled to the palate, inset, and the donor site closed.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Velopharyngeal assessment
Time Frame: 6 Months
The points measured to assess velopharyngeal anatomy are: Velar Length Pharyngeal Depth, Effective Velar length, Velar thickness, VP Gap. All measurements will be in mm. 3D T2-weighted sequence is used to capture high-resolution anatomical details at rest. Rapid 2D sequences assess velopharyngeal closure during sustained phonation. Sagittal and oblique coronal views will be captured. The sagittal plane provides an overall view of velopharyngeal structures, while the oblique coronal plane is specifically designed to visualize the LVP and assess closure pattern. Measurements on the MRI will be taken by primary and secondary raters to examine the intra- and inter-observer reliability. All patients will have their MRI taken with the same machine with uniform MRI acquisition parameters
6 Months
VP ratio
Time Frame: 6 months
this is a ratio calculated by dividing Velar length/Pharyngeal depth.
6 months
EVP ratio
Time Frame: 6 months
This is a ratio calculated by dividing Effective Velar length/Pharyngeal depth
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Speech intelligibility
Time Frame: 6 months after surgery
By Standardized articulation tests, speech intelligibility will be scored according to speech intelligibility scale, ranged from 0 to 3 (0 = within normal limits, 1 = mild speech intelligibility, 2 = moderate speech intelligibility, 3 = severe speech
6 months after surgery
Hypernasality
Time Frame: 6 months after surgery
By Perceptual speech evaluation which will be done by the same speech pathologist for all patients. Perceptual speech assessment will be performed by recording the repeated different syllables, sentences and counting from 1 to 10 by the patients in a soundproof room. All the used sentences will be in Arabic language. The records will be assessed by the phoniatrician to detect the speech disorders as the severity of nasal resonance. the severity of nasal resonance will be scored according to the hypernasality scale ranged from 0 to 3 (0 = no hyper nasality, 1 = mild hypernasality, 2 = moderate hypernasality, 3 = severe hypernasality)
6 months after surgery
Nasal emission
Time Frame: 6 months after surgery
By Perceptual speech evaluation and will be evaluated qualitatively as absent or present.
6 months after surgery
