        A Simple, Reliable, and Inexpensive Intraoperative External Expansion System for Enhanced Autologous Structural Fat Grafting

        Oranges, Carlo M.,Tremp, Mathias,Ling, Barbara,Wettstein, Reto,Largo, Rene D.,Schaefer, Dirk J. Korean Society of Plastic and Reconstructive Surge 2016 Archives of Plastic Surgery Vol.43 No.5

        External volume expansion of the recipient site by suction has been proposed as a way of improving fat graft survival. The objective of this study was to present an innovative and simple intraoperative external expansion system to enhance small-volume autologous fat grafting (40-80 mL) and to discuss its background and its mechanism of action. In this system, expansion is performed using a complete vacuum delivery system known as the Kiwi VAC-6000M with a PalmPump (Clinical Innovations). The recipient site is rapidly expanded intraoperatively 10 times for 30 seconds each with a negative pressure of up to 550 mm Hg before autologous fat injection. During this repetitive stimulation, the tissues become grossly expanded, developing macroscopic swelling that regresses slowly over the course of hours following the cessation of the stimulus. The system sets various mechanisms in motion, including scar release, mechanical stimulation, edema, ischemia, and inflammation, which provide an environment conducive for cell proliferation and angiogenesis. In order to maintain the graft construct in its expansive state, all patients are encouraged postoperatively to use the Kiwi three times daily for one minute per session over the course of three days. The handling of this system is simple for both the patients and the surgeon. Satisfactory clinical outcomes have been achieved without significant complications.

      • The Phonetic and Linguistic Environment of Third Singular Allomorphs in Parent Input

        Purpose: The third person singular present tense morpheme (3s) has a protracted course of development for children with language disorders and for typically developing children compared to other phonetically or linguistically similar morphemes. This study’s objective is to describe the phonetic and linguistic environment of 3s allomorphs in parent input. Methods: Participants were 14 monolingual English-speaking parents of typically developing toddlers. Parents’ allomorphs of 3s were examined for sentence position, allomorph type, coda of the inflected verb, onset of the following word, and the verb’s input frequency both before and after the toddlers first used 3s. Results: At both measurement points, the majority of instances of 3s were sentence medial, took the form of an/s/or/z/allomorph, and both followed and preceded non-sibilant consonants. At the second measurement point, when emergence of 3s had begun for all children, parents inflected a significantly greater number of different verb types with 3s. Parents also inflected a greater number of verbs with low frequency in parent input at Time 2, as demonstrated through the calculation of a Weighted Verb Diversity score. Conclusions: The findings of this study are both compatible with previous investigations of phonetic and linguistic environment and also build on those findings by examining the environment in greater detail. Speech-language pathologists could consider selecting target verbs that are intransitive and end with sibilants to increase the salience of the 3s morpheme for clinical populations at risk for delayed acquisition of the 3s morpheme.
