\nThe incisive foramen divides the primary palate from the secondary palate. Either may occur in the complete or incomplete forms. Although anatomically distinct, they are commonly occur together.<\/p>\n
Steps in the Procedure<\/em><\/p>\n 1. The palate is exposed with a Jennings or Dingman mouth gag or cheek retractors<\/p>\n 2. A 2-0 silk suture is placed through the tongue to act as stay sutures to pull the tongue forward. Alternately, the tongue is retracted out of the operative field using a tongue retractor.<\/p>\n 3. The internal pterygoid muscle is identified as a marker for the plane of mobilization of the soft palate.<\/p>\n 4. A #15 scalpel is used to incise the mucosa and periosteum medial to the alveolar ridge.<\/p>\n 5. The incision is curved laterally (outwards toward the lips) at the posterior end of the alveolar ridge.<\/p>\n 6. The incision is continued posteriorly to a position in the plane of the uvula.<\/p>\n 7. A mucosal\/periosteal flap is raised via blunt dissection with a nasal freer the entire length of the incision.<\/p>\n 8. Care must be taken to not break through the mucosa at the cleft edge anteriorly.<\/p>\n 9. The mucosal\/periosteal flap is raised posteriorly to expose the tensor veli palatini muscle with care being taken to not disrupt the posterior palatine vessels.<\/p>\n 10. The internal pterygoid muscle and tendon is exposed at the posterior edge of the raised mucosal\/periosteal flap and the space medial is opened widely using blunt dissection and displacing the tonsils and tonsillar pillars medially.<\/p>\n 11. Blunt dissection with the nasal freer or sharp dissection with a #15 blade is performed to separate the flap from the palatine bone near the origin of the pterygoid muscle.<\/p>\n 12. The edge of the hamulus is identified by palpation and exposed with the internal pterygoid muscle serving as a landmark.<\/p>\n 13. Some surgeons fracture the hamulus using a small osteotome to release tension on the tensor veli palatini muscle, although this is controversial as it may lead to damage to the eustachian tube and impair function.<\/p>\n 14. A #15 scalpel is used to separate the soft palate from the posterior edge of the hard palate.<\/p>\n 15. The area of dissection is packed with gauze and the identical steps listed above are performed on the contralateral (opposite) side.<\/p>\n 16. A 5-0 Dermalene stay suture is placed through the uvula and gentle tension is placed on it.<\/p>\n 17. A #17 scalpel is used to make an incision along the medial margin of the cleft<\/p>\n 18. The edge of the hard palate is identified with sharp dissection to develop the layers of the oral mucosa and nasal mucosa.<\/p>\n 19. The edge of the soft palate is identified with sharp dissection to develop the layers of the oral mucose, nasal mucosa, and the middle muscle layer.<\/p>\n The incisive foramen divides the primary palate from the secondary palate.
