Langerbeck's repair
restoration of levator veli palatini
mordified restoration of tensor veli palatini
Langerbeck's repair of cleft palate,without specific restoration of levator veli palatini or tensor veli palatini. Incisions along the margins of the cleft at the junction of oral and nasal mucosa. Lateral relaxing incisions were performed and the mucoperiosteal flap of hard palate were elevated on both sides except the ones with only soft palate cleft. The anterior end of the mucoperiosteal flap may be cut off for the purpose of tension relieving and would be resutured to the anterior area during closing. In the soft palate, the division was made between the oral mucous layer and the palatal musculature layer. Hamulus were broken for closing the cleft without tension. Closing was done by two seperated layers, one layer of nasal mucosa-palatal muscle, and one layer of oral mucosa.
The incision was made similar to Langerbeck's repair. During disection, the levator veli palatini was identified after the elevation of flap. The levator veli palatini was separate from the oral and nasal mucosa. During closing, the anterior end of levator veli palatini was rotated towards the midline and the two muscle bundle from the two sides were sutured in the midline. In this process, the tensor veli palatini was not intentionally identified or dissected.
Incision was made similar to Langerbeck's repair. During disection, the tensor veli palatini was identified after flap elevation. Its tendinous fibers was released from but still connected to the pterygoid process without breaking the hamulus or cutting off the tendinous fibers. If the tension is too strong during suturing, the tensor tendon could be partly dissected laterally meanwhile be kept continuity medially so that the tensor veli palatini could be rotated more medially. The levator veli palatini, tensor veli palatini, together with the palatine aponeurosis and the nasal mucosa from two sides were sutured in the middle line. The tensor veli palatini may not be jointed to the contralateral one directly.
