Safety and Efficacy Concerns of Autologous Fat Grafting for Velopharyngeal Insufficiency.

OBJECTIVE: Autologous fat grafting of the velopharynx has been well described for the treatment of velopharyngeal insufficiency (VPI), with most studies purporting it as a technique with low morbidity useful in the treatment of mild VPI. Prompted by 3 cases of obstructive sleep apnea (OSA) following fat grafting of the velopharynx, we undertook a review of the outcomes of this procedure at our unit. DESIGN: Retrospective case series. PARTICIPANTS: All patients who underwent autologous fat grafting for VPI at the Royal Children's Hospital Melbourne. MAIN OUTCOME MEASURES: Preoperative nasendoscopy findings, perceptual speech assessment results, and rates of revisional surgery and complications. RESULTS: Twenty-eight patients were included in the study. Three patients (11%) developed severe OSA requiring removal of the grafted fat. In a subanalysis of cleft patients, there was a reported improvement in hypernasality in 63% though only 25% had complete resolution of their hypernasality. Patients who had an improvement in speech were more likely to have a velopharyngeal gap of less than 0.5 cm2 on preoperative nasendoscopy. All 3 patients who developed OSA had syndromes associated with hypotonia. CONCLUSIONS: This study raises serious concerns over the safety and efficacy of fat grafting for VPI. Overall, there was a relatively high complication rate with generally poor speech results in our series of patients. Stringent criteria should be used to select candidates for fat grafting, namely, a velopharyngeal gap less than 0.5 cm2 and the absence of a syndrome associated with hypotonia.

Healing time and incidence of hypertrophic scarring in paediatric scalds.

INTRODUCTION: Scald burns, which heal in less than 14 days, are seen to be at low risk of hypertrophic scar (HTS) formation. Consequently surgery is usually reserved for scalds likely to take more than 14 days to heal. With the use of silver based dressings over the past few years, anecdotally, we have observed a tendency to improved healing of scalds with conservative management and reduced need for surgical intervention. We aimed to investigate the effect of overall healing time of paediatric scalds on HTS formation over a five-year period (2011-15). METHODS: We retrospectively identified all new patients attending the Royal Children's Hospital (RCH) burns clinic from 31st January 2011-31st July 2015. Medical histories were reviewed for burns caused by scalds. Scar quality was determined from written records or clinical photographs. Patients were compared in groups based on healing time of <10 days, 10-14 days, 15-21 days, 22-30 days or >30 days. RESULTS: We studied 322 children, of which 52 (16.1%) developed HTS. There was a significantly higher incidence of HTS with increased time to healing (mean 34.5 days compared to 12.1 days, p<0.01). There were 25 patients that underwent surgical treatment with excision or debridement and split thickness skin graft of which 21 (84%) developed HTS. Grafting offered no benefit in HTS rate in the 22-30 days to heal group. CONCLUSIONS: Our study confirms that there is a link between prolonged healing time of scald wounds and HTS. The danger of slow healing for scarring despite grafting, suggests this operation should be performed earlier than current practice to allow complete healing in less than 3 weeks.

Fatty hypertrophy cause obstructive sleep apnea after fat injection for velopharyngeal incompetence.

INTERVENTION: Soft tissue augmentation of the posterior pharyngeal wall and the soft palate is reported to reduce velopharyngeal incompetence, and fat grafting in selected patients has shown effective and lasting results for restoring normal resonance. Potential complications of soft tissue augmentation for velopharyngeal incompetence include obstructive sleep apnea. PATIENT: An 8-year-old boy with velopharyngeal incompetence and a small velopharyngeal gap underwent a fat injection procedure and subsequently developed obstructive sleep apnea concomitant with a significant weight gain. Videofluoroscopy and nasendoscopy showed a remarkable enlargement of the grafted fat areas that required a soft palate debulking procedure, significantly improving obstructive sleep apnea. CONCLUSION: This is an unusual case where alteration in volume of grafted fat at the recipient site is suspected of causing obstructive sleep apnea. It is also an example of long-term fat graft survival and fat graft overgrowth.

Measuring cranial vault volume with three-dimensional photography: a method of measurement comparable to the gold standard.

The gold standard for measuring cranial vault volume is a computed tomography (CT) scan. Computed tomography scans in the pediatric population carry the significant risk of inducing a malignancy later in life. In a novel study, we show that a three-dimensional (3D) photograph can be used to measure and track cranial vault volume changes in craniosynostosis patients. In a study of adequate power as determined by pre hoc analysis, we demonstrate a greater than 0.91 correlation coefficient between volume as measured by CT and 3D photograph in more than 70 patients presenting to a tertiary craniofacial center (P < 0.001). Volume above a plane running through the lateral canthus (ex) and tragus (t) sag-ex-t on the digital 3D photograph differs from CT by a mean percentage difference of 31.9% (SD, 14.0%; 95% confidence interval, P < 0.0001). A linear regression model was used to determine the equation describing the relationship between volume as measured by 3D photograph and CT; with this equation, the absolute volume of the cranial vault is easily determined using only the 3D image. Interrater reliability is high (>0.99, ICC). The ability to measure cranial vault volume from the 3D photograph adds an important dimension to the complete and objective analysis of skull growth and postoperative change.

Refining trunk contouring with reverse abdominoplasty.

BACKGROUND: The reverse abdominoplasty is an effective technique for selected patients seeking treatment for upper abdominal tissue excess and laxity. Specifically, the procedure is particularly effective in patients who have previously undergone conventional abdominoplasty or liposuction and have residual upper abdominal contour problems. It is a versatile technique that may be combined with a number of adjunctive procedures, notably autologous breast augmentation with the excess upper abdominal tissue. METHODS: The authors reviewed their experience with the reverse abdominoplasty in a series of 14 consecutive patients who underwent surgery over a five-year period. Patient case notes, as well as and pre- and postoperative clinical photographs, were analyzed. Furthermore, patients were directly questioned to assess their surgical result. RESULTS: The mean age of the cohort was 56.6 years and the majority of patients had undergone previous abdominal or breast aesthetic surgery. A mean of 6 cm of upper abdominal tissue was excised, weighing a mean of 326 g. There were no major complications and only three patients had to undergo minor revisional surgery postoperatively. CONCLUSIONS: The authors present their surgical outcomes and discuss the indications, benefits, and lessons they have learned from their experience with this useful technique in relation to the published literature. The ideal candidate for this procedure appears to be a patient who is older, presents with excess upper abdominal skin, has had a previous conventional abdominoplasty, and who has existing inframammary scars.

Fascial suspension mastopexy combined with augmentation mammaplasty.

BACKGROUND: We have modified our technique of fascial suspension mastopexy to be used in combination with augmentation mammaplasty. This study aimed to assess the results of the combined procedure in our first consecutive 10 patients. The surgery aims to maximize long-term upper-pole fullness as well as optimal projection and shape in volume-depleted ptotic breasts. METHODS: A retrospective case notes review was carried out, with details of patient demographics, indications, operative detail, and postoperative assessment recorded. In addition, patients were directly questioned to gain their opinion of the procedure. RESULTS: Nineteen breasts were operated on in ten patients. On preoperative assessment two women (20%) had grade 3 ptosis and the rest had grade 2 (83%). The majority of women had had children and had breast-fed (70%). The mean follow-up period was 33 months (range = 4-55) and overall patient satisfaction was high despite six of the 10 patients undergoing minor scar revisions for dog-ears under local anesthetic and two undergoing implant exchange to correct minor asymmetries. There were no major postoperative complications in this series. All patients demonstrated good projection and upper-pole fullness at postoperative review. CONCLUSION: The combined technique of fascial suspension mastopexy and breast augmentation with implants is a safe and reliable method to correct ptosis in volume-depleted breasts. Patients should be counseled on the possible need for minor revisional procedures. Importantly, the technique achieves excellent upper-pole fullness and the projected and rejuvenated breast has an overall pleasing result.
