Virtual Surgical Planning in Subscapular System Free Flap Reconstruction of Midface Defects.

OBJECTIVES: Reconstruction of the midface has many inherent challenges, including orbital support, skull base reconstruction, optimizing midface projection, separation of the nasal cavity and dental rehabilitation. Subscapular system free flaps (SF) have sufficient bone stock to support complex reconstruction and the option of separate soft tissue components. This study analyzes the effect of virtual surgical planning (VSP) in SF for midface on subsite reconstruction, bone segment contact and anatomic position. MATERIALS AND METHODS: Retrospective cohort of patients with midface defects that underwent SF reconstruction at a single tertiary care institution. RESULTS: Nine cases with VSP were compared to fourteen cases without VSP. VSP was associated with a higher number of successfully reconstructed subunits (5.9 vs 4.2, 95% CI of mean difference 0.31-3.04, p = 0.018), a higher number of successful bony contact between segments (2.2 vs 1.4, 95% CI of mean difference 0.0-1.6, p = 0.050), and a higher percent of segments in anatomic position (100% vs 71%, 95% CI of mean difference 2-55%, p = 0.035). When postoperative bone position after VSP reconstruction was compared to preoperative scans, the difference in anteroposterior, vertical and lateral projection compared to the preoperative \u27ideal\u27 bone position was82% of measurements. There were no flap losses. CONCLUSION: VSP may augment SF reconstruction of the midface by allowing for improved subunit reconstruction, bony segment contact and anatomically correct bone segment positioning. VSP can be a useful adjunct for complex midface reconstruction and the benefits should be weighed against cost

Alone but Flowing: The Effects of Autotelic Personality and Extraversion on Solitary Flow

Flow, a psychological state of intense engagement in and enjoyment of an activity, can arise during both solitary and socially-interactive experiences. Whereas people high in extraversion have difficulty achieving flow in solitude, those with an autotelic personality—a combination of traits that make people particularly prone to flow—readily experience flow in both solitary and interactive conditions. This Stage 1 report preregisters an experiment to investigate whether autotelic personality mitigates the negative association between solitary flow and extraversion. Participants and their romantic partners (target N=190) will play the game Perfection™ in three conditions (order will be counterbalanced): alone (solitary condition), in the presence of their partner without interaction (mere-presence condition), and collaboratively (interactive condition). We hypothesize that autotelic personality will positively predict flow in all conditions, whereas extraversion will positively predict flow in the interactive condition and negatively predict flow in the solitary and mere-presence condition. We further hypothesize that the (negative) effect of extraversion on flow in the solitary condition will be weaker among participants high in autotelic personality. The findings will shed light on the role of personality in promoting solitary flow experiences, and particularly how traits might interact to determine optimal and non-optimal conditions for achieving flow
