Comparison of the Effect of the Rotation Palatoplasty and V-Y Pushback Palatoplasty Techniques on Palate Elongation With Magnetic Resonance Imaging
(Churchill Livingstone, 2015) Isik, D.; Bora, A.; Yuce, S.; Davran, R.; Kocak, O. F.; Canbaz, Y.; Atik, B.
Most surgical techniques used in cleft palate repair require the extension of the palate to the pharynx. However, no adequate information exists regarding the extent to which this elongation obtained during operation continues in late postoperative period. In this study, we compared and measured palate elongation in patients with a cleft palate who underwent a V-Y pushback or rotation palatoplasty, by means of magnetic resonance images obtained before and 1 year after surgery. The hard palate, soft palate, and total palate lengths were measured for all of the patients, and the velopharyngeal opening area width was calculated. In patients who underwent the V-Y pushback technique (n = 13), the total palate and soft palate lengths were shortened by an average of 0.10 and 0.14 cm after surgery, respectively. However, the hard palate length was elongated by an average of 0.13 cm. In the rotation palatoplasty group (n = 13), the total palate, hard palate, and soft palate lengths were elongated by 0.57, 0.10, and 0.49 cm, respectively. The velopharyngeal opening was narrowed by 0.06 cm(2) using the V-Y pushback technique and by 0.29 cm(2) using the rotational palatoplasty. This study demonstrated that the palate does not elongate during the V-Y pushback technique, as expected. However, rotational palatoplasty elongates the soft palate.
New Suggestions for Correction of the Severe Hypospadias Complications
(Turkish Society of Plastic Reconstructive, and Aesthetic Surgery, 2015) Işik, D.; Bilici, S.; Canbaz, Y.; Gecit, I.; Yüce, S.; Atik, B.
Background: Severe hypospadias complications are defined as large urethral fistulae, chordee recurrence, and severe scar or skin defect limiting urethral reconstruction from the penis skin, and complications persisting in spite of multiple operations. In this study, new flap techniques applied on six patients with severe hypospadias complications have been introduced. Methods: The 6 patients with hypospadias surgery complicationsand a mean age of 15.5 years, had undergone hypospadias repair operations an average of 4.5 times. Four cases had undergone repair using the Kutlay technique, one was repaired by island-formed penile skin flap, and the remaining case was repaired using a groin flap prefabricated by skin graft. Results: In one of the patients, meatal stenosis was found in the first postoperative month. It was treated by continuous and intermittent urethral catheterization. In another patient, purulent drainage was observed secondary to postoperative soft tissue infection. A 0.2 cm urethra-cutaneous fistula was observed on the subcoronal region in the postoperative sixth month in this patient. Other patients had no chordee recurrence, fistula, urethral stenosis or other complications. Conclusions: In patients with severe hypospadias complications, case-specific and reliable treatment options that may repair each component of the deformity should be used. As the severity of the deformity increases, more complicated and multiple-session techniques may be preferred for treatment.
