Autologous fat transplantation to the velopharynx for treating mild velopharyngeal insufficiency: A 10-year experience.

BACKGROUND: For the last two decades, autologous fat transplantation has been used to treat mild velopharyngeal insufficiency (VPI); however, there is still disagreement about its effectiveness. The aim of the study was to evaluate the procedure by using speech analysis and magnetic resonance imaging (MRI). PATIENTS AND METHODS: This is a prospective study of 47 non-syndromic patients with mild VPI who underwent autologous fat transplantation to the velopharynx between 2006 and 2015. Thirty-two patients had a cleft palate, all of which had been repaired before fat transplantation. Eight patients developed VPI after adenotonsillectomy, one after uvulo-palatoplasty and six had VPI of unknown etiology. Twelve patients underwent two procedures of fat transplantation. Preoperative and 1-year postoperative audio recordings were blinded for scoring independently by three senior speech therapists on a five-point scale. Preoperative and 1-year postoperative MRIs were obtained during phonation, measuring the velopharyngeal distance and the velopharyngeal gap area. Correlations between the speech outcomes and MRI were calculated. RESULTS: Audible nasal emission was the only speech parameter that improved significantly postoperatively (p = 0.005). A significant reduction in both velopharyngeal distance (p < 0.005) and the gap area (p < 0.005) was found after treatment. A significant improvement in the mobility of the velum was observed after treatment (p = 0.03). There was no significant correlation between speech outcomes and MRI. CONCLUSIONS: Autologous fat transplantation for the treatment of mild VPI, although significantly reducing audible nasal emission, made no significant improvement in hypernasality or nasal turbulence. No complications were observed.

Impact of orthognathic surgery on velopharyngeal function by evaluating speech and cephalometric radiographs.

BACKGROUND: Maxillary retrognathia is a well-known consequence of abnormal facial growth in patients with cleft lip and palate. Orthognathic surgery improves facial appearance and occlusion but may induce velopharyngeal insufficiency. The aim of this study was to evaluate the effect of orthognathic surgery on velopharyngeal function by using speech analysis and lateral cephalometric radiographs. PATIENTS AND METHODS: We conducted a retrospective study of 47 patients who underwent maxillary advancement ±â€¯mandibular setback between 2006 and 2016. Preoperative and 1 year postoperative audio recordings were blinded for scoring by three trained speech therapists. Preoperative and 1 year postoperative lateral cephalometric radiographs were used to obtain information about skeletal movement and its relationship with the velopharyngeal area. Correlations between speech outcomes and cephalometric radiographs were determined. RESULTS: Hyponasality improved significantly after surgery (p < 0.05), whereas hypernasality deteriorated significantly only in patients who underwent maxillary advancement alone (p < 0.05). No difference in speech parameters was found between patients with hypernasality or patients who had a pharyngoplasty preoperatively and the rest of the group. No correlation was found between the amount of maxillary advancement and hypernasality. A significant correlation (r < -0.49, p < 0.05) was found between the preoperative velar length and hypernasality postoperatively. CONCLUSIONS: Maxillary advancement has a negative impact on velopharyngeal function, whereas bimaxillary surgery seems to protect from deterioration. No difference was found in the amount of maxillary advancement or in velopharyngeal measurements between the Le Fort I group and the bimaxillary group. A short soft palate is a predictor of hypernasality after orthognathic surgery.

Quality of life, patient satisfaction and cosmetic outcome after breast reconstruction using DIEP flap or expandable breast implant.

In a cross-sectional postal survey, we compared patient-reported outcomes in patients undergoing breast reconstruction with the deep inferior epigastric perforator (DIEP) flap or an expandable breast implant (EBI). We included 34 consecutive patients who had breast reconstruction with DIEP flap and 30 patients with EBI. Outcomes were assessed using the Short Form 36 (SF-36) quality of life questionnaire, two study-specific patient satisfaction questionnaires and a visual analogue scale (VAS) on cosmetic result. There were no significant differences in SF-36 subscale scores between the two groups. On the study-specific questionnaire, more patients in the DIEP group were satisfied with the appearance of their breast (P<0.0005) and reported an improved social relationship (P=0.02), and fewer patients were sad about their body image (P=0.01) after reconstruction than in the EBI group. On the other study-specific items, satisfaction was similar in the two groups. On all five VAS items, DIEP patients reported better cosmetic results than EBI patients. We conclude that patient satisfaction and cosmetic outcome were better after breast reconstruction with the DIEP flap compared with EBI, while there was no difference in health-related quality of life.

Curve progression and spinal growth in brace treated idiopathic scoliosis.

The risk of progression of idiopathic scoliosis is correlated primarily to factors that predict potential remaining skeletal growth. The aim of the current study was to evaluate spinal growth, measured as the length of the scoliotic spine on serial longitudinal radiographs, and its relationship to progression of the scoliotic curve. The retrospective study was based on measurements made on standing anteroposterior radiographs of 60 patients with adolescent idiopathic scoliosis. In all patients, a Boston brace was prescribed during the followup period. Despite brace treatment, a significantly greater average progression rate of the scoliotic curve was seen in periods of rapid to moderate growth (> or = 10 mm per year) compared with periods of small or no growth (< 10 mm per year). The difference in progression rates concerned the increase of the Cobb angle and the increase of lateral deviation and axial rotation. These findings indicate the length of the spine measured on subsequent radiographs is an excellent parameter to determine spinal growth and thus an excellent predictor of scoliosis progression. With the presented growth charts, which were derived from the measured individual growth velocity values of the patients in the study, it is possible to predict future spinal growth at different chronologic ages.
