Plastic surgery; its principles and practice . e soft palate the depth towhich the tissues are split. The tissue internal to the line FG should be loosened andturned inward. The insert represents a transverse vertical section along the line The margins of the flaps M and N, and the upper plane of the soft palate are suturedtogether. The insert indicates the method of turning and suturing. 3. The mucoperi-osteal flap O is then shifted over the sutured line and secured, and the lower plane of the softpalate is sutured. defect was too wide for the edge-to-edge closure. The diagrams willfully explain the principle (Fig. 253). Lanes method is based on the Davies-Colley method. Lane raisesa flap of mucoperiosteum from one side, with its base close to the marginof the cleft. Then on the opposite side the mucoperiosteal flap isundermined through an incision along the margin of the cleft. Thefree edge of the flap from the opposite side is then drawn into this pocket,and is held by sutures (Figs. 254-260). HARELIP AND CLEFT PALATE 291. Fig. 254.—Lanes operation for complete unilateral cleft palate (Binnie).—Reflect theflap outlined by the dotted line 7, 5. 6, 8. Make the incision through the mucoperiosteumto the bone on the hard palate, but only through the subniucosa in the soft palate. Theline 5 to 6 is made on the outer surface of the alveolus near the reflection of the mucosa tothe cheek. When the flap is raised the posterior palatine vessels are caught and the side of the cleft attached to the septum pull the uvula and soft palate forward toexpose the nasal surface. Divide the posterior external edge of the soft palate 4, 3,through the submucosa and extend this incision along the nasal surface of the hard andsoft palate to the cleft 3, 2. The incision down to the bone is continued along the cleft 2, i,and across the alveolus margin i, 9.
