The Importance of Radical Intravelar Veloplasty during Two-flap Palatoplasty

Background: The purpose of this study was to compare the two-flap palatoplasty technique for cleft palate repair, with and without radical intravelar veloplasty, with special emphasis on the fistula rate and speech outcome. Methods: A retrospective, time-series cohort of 213 consecutive patients with primary two-flap palatoplasty before and after the introduction of a radical intravelar veloplasty was studied. The main outcome measures were immediate postoperative complications, oronasal fistula rate, and speech. A perceptual speech evaluation was performed by two speech pathologists and included hypernasality, nasal emission, articulation, intelligibility, and overall velopharyngeal competence. The need for secondary palate surgery for velopharyngeal insufficiency was also analyzed. Results: There were no differences in postoperative complications between the two study groups. Postoperative morbidity occurred in six patients (2.8 percent) and consisted of two patients with respiratory compromise, two patients who required reoperation for bleeding, and two patients with oronasal fistula. Perceptual speech evaluation demonstrated significantly better speech outcomes (81.9 percent versus 49.5 percent, p < 0.001) and a significantly lower rate of secondary palate surgery for velopharyngeal insufficiency (29 percent versus 6.7 percent, p = 0.008) in the radical intravelar veloplasty group. The most important predictive factor of speech outcome was the addition of a radical intravelar veloplasty (odds ratio, 0.175; 95 percent confidence interval, 0.039 to 0.785). Conclusions: Despite study design limitations, such as experience bias and follow-up differences, this study demonstrates that radical intravelar veloplasty may enhance the functional results of the two-flap palatoplasty without increasing postoperative morbidity. A novel classification of the muscle repair is proposed based on the amount of muscle dissection and retropositioning.

Achieving growth and excellence in medicine: the case history of armed conflict and modern reconstructive surgery.

November 11, 2009 will mark over 90 years of commemorating Armistice Day, the end of World War I. Although conflict in the Middle East reminds us that WWI failed to end all wars, it did serve as both substrate and catalyst for the development of modern plastic and reconstructive surgery. This article will outline those ingredients most directly responsible for the growth of the specialty, tracing its development in response to armed conflict, and implications for continued excellence both in reconstructive surgery and other fields in the future.

Effectiveness and safety of autologous fat grafting to the soft palate alone.

BackgroundPosterior pharyngeal augmentation is an accepted method of treating velopharyngeal insufficiency (VPI). Techniques using autologous fat harvest, preparation, and grafting are well described. Based on the complications from retropharyngeal injection, we performed augmentation of the nasal surface of the palate to reduce hypernasality with decreased risks. MethodsAfter Institutional Review Board approval, a chart review from 2010 to 2013 identified 46 patients with cleft palate, subjective and nasoendoscopic evidence of VPI treated with autologous fat grafting to the soft palate. Speech evaluation of velopharyngeal function was compared before and after autologous fat grafting. ResultsA total of 61 autologous fat grafting procedures were performed in 46 patients. The average age of the study population is 5.59 ± 2.05 years. The majority underwent a single procedure (32/46 or 69.6%), 13 of 46 patients (28.2%) had 2 fat grafting procedures and only 1 patient (2.2%) had 3 fat grafting procedures. The fat was injected primarily in the soft palate. The recorded volume of fat grafted averaged 2.4 ± 1.1 mL. Average operative time was 39 ± 12.55 minutes. There were no local or donor site complications. Four patients were lost to follow-up. Of 34 patients with adequate speech follow-up, including Pittsburgh Weighted Speech Scale (PWSS) assessment, the average preoperative score of 8.17 ± 3.59 was reduced to 5.17 ± 3.14 postoperatively. Although 26 of 34 patients (76.5%) had an improvement in their PWSS score, only 13 of 34 patients (38.23%) saw an improvement in their PWSS category. ConclusionsAutologous fat grafting to the soft palate is a safe operation with minimal risks. Speech outcomes are subjectively enhanced in the majority of patients, with a full PWSS category improvement seen in 40% of the cases. Patient selection criteria to optimize results are provided.

Deep dopamine extravasation injury: a case report

We report the case of a 3-month-old girl with Downs syndrome, who sustained a deep and massive extravasation of dopamine, resulting in segmented, full-thickness skin necrosis and transient brachial plexus palsy of her left upper extremity. The patient was managed conservatively, including wound care, de-bridement of necrotic tissue, secondary wound healing and intensive physical therapy. The patient showed a satisfactory outcome with complete secondary closure of her wounds and full brachial plexus recovery after 1 year of follow-up. The mechanism of action of dopamine in the deep soft tissue, the difficulties of an adequate diagnosis of a deep dopamine extravasation and alternative treatments are presented in this article.

Further delineation of the Kapur–Toriello syndrome†

The Kapur–Toriello syndrome (KTS) is a rare multiple congenital anomaly syndrome, with presumed autosomal recessive inheritance based on the initial report of affected siblings. Here we report on a female with multiple anomalies, including cleft lip and palate, coloboma, mental retardation with cerebral atrophy, and imperforate anus who, upon re‐evaluation at 30 months, was recognized to have a columella that extended below the nares. This distinctive finding prompted the diagnosis of KTS. This is the 5th report of KTS, and the second female. Interestingly, both female cases also manifest an ano/rectal malformation, suggesting that this should be considered a component manifestation of this rare syndrome.

Safety profile of wire osteosynthesis in craniosynostosis surgery.

With the advent of resorbable systems, most surgeons have stopped using wires for craniofacial fixation. Although numerous large retrospective reports regarding craniofacial surgery have been published, no documentation exists regarding the disadvantages or complications associated with wires. We review our experience with 47 consecutive patients with bicoronal and unicoronal craniosynostosis where wire osteosynthesis alone was used. Nine patients (19.1%) developed wire-related complications, but only 5 patients (10.6%) required reoperations. No other complications were observed including growth restrictions, implant migration, or interference with radiographic imaging. These results are comparable to those reported in the literature for other fixation systems and demonstrate that wires are a safe means of fixation of the cranial vault in infancy.

IL-10 and IL-4 in skin allograft survival induced by T-cell depletion plus deoxyspergualin.

The mechanisms mediating T-cell depletion plus 15-deoxyspergualin (DSG)-induced prolonged allograft survival or tolerance are uncertain. The purpose of this study is to evaluate the role of IL-4 and IL-10 in prolonged allograft survival induced by T-cell depletion plus DSG. MHC mismatched skin allograft transplantation was performed, using wild-type and three separate knockout (i.e., IL-4–/–, Stat6–/-, or IL-10–/–) mice as recipients. Induction therapy consisted of T-cell depletion and or brief course of DSG. The data demonstrate that monotherapy with T-cell-depleting mAbs or DSG prolonged skin allograft survival, compared to controls, in wild-type Balb/c recipients [median survival time (MST) = 25 and 21 vs. 10 days, p < 0.007]. T-cell depletion plus DSG further augmented skin allograft survival in wild-type animals relative to monotherapy (MST = 35 days vs. 25 and 21 days, p < 0.006 vs. mAbs or DSG only), and was equally effective in IL-4–/– and Stat6–/– recipients. In contrast, combined therapy was no better than monotherapy in IL-10–/– animals (p > 0.05). Furthermore, skin allograft survival after combined therapy was shorter in IL-10–/– versus wild-type recipients (MST 20 and 41 days, respectively, p < 0.001). IL-4-mediated signaling through Stat6 is dispensable for prolonged allograft survival induced by T-cell depletion plus DSG. In contrast, IL-10 appears to be important for prolonged allograft survival induced by combined therapy in this model.
