Clinical efficacy of Hogan posterior pharyngeal flap in repairing velopharyngeal insufficiency secondary to cleft palate in older patients.

Objectives: The clinical effects and surgical procedures of Hogan posterior pharyngeal flap in the treatment of the older patients with velopharyngeal insufficiency (VPI) after cleft palate repair were investigated.
Methods: A total of 33 patients (aged 10-35 years; average of 20.4 years) with VPI secondary to cleft palate were included. They underwent Hogan posterior pharyngeal flap to improve velopharyngeal closure function. The clinical efficacy of the ope-ration was evaluated with Chinese speech clarity measurement and nasopharyngeal fiberscope (NPF), and the velopharyngeal closure was graded. The average follow-up time was 13.3 months.
Results: The wounds of all patients were healed by first intention, and speech assessment showed that the consonant articulation increased and the rate of hypernasality and nasal emission decreased significantly ( P <0.05). NPF examination showed that the postoperative velopharyngeal closure function significantly improved, 30 cases (91%) were gradeⅠ, and 3 cases (9%) were grade Ⅱ.
Conclusions: Hogan posterior pharyngeal flap for VPI secondary to cleft palate can significantly improve velopharyngeal closure.
