Furlow – pharyngeal flap – velopharyngeal insufficiency –
resonance- Speech outcome. |
| |
Objective: This is a retrospective study comparing between Furlow and
Pharyngeal Flap techniques in treatment of velopharyngeal insufficiency
regarding complications and resonance outcomes (including hypernasality,
articulation errors, air emission, speech intelligibility).
Patients and Methods: Twenty eight patients were operated for correction of
velopharyngeal insufficiency between April 2010 and July 2012. Patients
fulfilled two criteria; velopharyngeal dysfunction unresponsive to speech
therapy and a moderate (40-50 percent) coronal gap on nasopharyngoscopy.
Sixteen patients were subjected to Furlow technique and twelve patients to
pharyngeal flap technique. All patients were evaluated preoperatively and 7
to 10 days post-operatively to evaluate the organic aspect then 2 to 6 months
postoperatively with perceptual speech analysis and flexible fiber-optic
nasopharyngoscopy. The patients were assessed for resonance rating to be
compared with preoperative one.
Results: Both Furlow and pharyngeal flap have a significant effect on
treatment of hypernasality. Pharyngeal flap has a significant effect on
management of pharyngalization of fricatives and facial grimace. Furlow has
a significant effect on treatment of regurgitation. No significant difference was
observed between Furlow and Pharyngeal flap techniques regarding
complications and resonance outcomes.
Conclusion: Pharyngeal flap technique and Furlow double opposing Z plasty
technique, both are effective in treatment of hypernasality and have no
significant difference in the postoperative resonance outcome and rate of
development of postoperative complications when used for management of
velopharyngeal insufficiency. |
