Management of secondary nasolabial deformities after bilateral cleft lip repair / 中华整形外科杂志

<p><b>OBJECTIVE</b>To evaluate the method to correct the seconary nasolabial deformities after the surgical treatment in the patients with bilateral cleft lip.</p><p><b>METHODS</b>From January 2000 to June 2003, forty patients with secondary deformities following repair of bilateral cleft lip were treated with a combined treatment procedures. AU of the forty cases underwent the following preoperative treatments: alveolar bone graft in 28 cases, preoperative orthodontics in 22 cases, prosthodontics in 20 cases and orthognathic surgery or distraction osteogenesis treatment in 20 cases, respectively. In order to improve the enlongation of nasal column, reconstruction of Cupid's bow, philtrum and correction procedures, continuous incision was made from the vermilion in median of the upper lip, the scar edge, the bilateral sides of the nasal column to the inner side of the nose, even extending the bilateral incision to nasolabial groove and nostril fundus.</p><p><b>RESULTS</b>Forty patients were got the follow-ups for 3 months to 3.5 years and the satisfactory rate reached 95%.</p><p><b>CONCLUSION</b>It is natural to emphasize the setting up of odontomaxillary frame and then utilize the surgical procedure to correct the secondary nasolabial parenchyma deformities. The method could be feasible and reliable for the correction of the secondary nasolabial parenchyma deformities after bilateral cleft lip repair.</p>

CT assist in surgical design for the posterior pharyngeal flap / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To establish a method for assist design of the posterior pharyngeal flap (PPF).</p><p><b>METHODS</b>The width, length of velopharyngeal space in repose and phonation of "i" in 26 cases with VPI were measured with CT. The width and length of PPF needed, the location of the pedicle and the contact position with the soft palate were analyzed.</p><p><b>RESULTS</b>The width of velopharyngeal space in repose ranged from 15.10 to 37.25 mm, with the average of 27.01 mm, the length was 12.54 to 30.39 mm, with the average of 22.10 mm. The width in phonation of "i" was 9.11 to 34.06 mm, with the average of 17.69 mm, the position of the pedicle wasall located at the level of the first cervical vertebra or above and the contact area of the flap with the soft palate was in the middle posterior 1/3 mostly.</p><p><b>CONCLUSION</b>As a method to quantitatively evaluate velopharyngeal function, CT can assist in design for the PPF.</p>
