Abstract Background The da Vinci single‐port (SP) robot is a new instrument for transoral robotic surgery (TORS) in oropharyngeal cancers (OPSCCs). We describe one‐year SP surgical outcomes and compare them to da Vinci Si outcomes. Methods Retrospective cohort study at a high‐volume TORS center. Consecutive patients undergoing TORS SP procedures from 10/2018 to 09/2019 were included. SP OPSCC outcomes were compared to a historical cohort of Si OPSCC patients. t tests were used to compare continuous variables; χ 2 or Wilcoxon rank‐sum tests were used to compare nonparametric categorical variables. Results Seventy‐eight patients underwent SP TORS. The bleed rate was 5.1%, mortality rate was 2.6%, and conversion rate was 0%. Compared to the Si cohort, OPSCC patients undergoing TORS SP procedures saw no significant differences in operative time or post‐TORS bleeds ( P > .05). Conclusions The SP is a comparably safe surgical instrument. Overall learning curve for the SP was rapid among experienced TORS surgeons.

Objectives/HypothesisDesign and test a novel biomaterial for injection laryngoplasty aimed to increase the duration of effectiveness of micronized acellular dermis.Study DesignAnimal model.MethodsInjection laryngoplasty was performed in three groups (n = 5) of New Zealand White rabbits. Acellular dermis was either used alone as a control (group 1), was combined with undifferentiated stem cells (group 2), or with predifferentiated chondrocytic cells (group 3). Groups 2 and 3 were supplemented with growth factors. Animals were sacrificed 4 and 12 weeks after laryngoplasty and histologic analysis was completed. The major outcome measure was volume of tissue remaining.ResultsAfter 4 weeks, the mean volume of tissue remaining was 341 ± 89 mm3, 295 ± 102 mm3, and 133 ± 15 mm3, for groups 1 to 3, respectively. At the 12‐week time point, volumes were 62 ± 62 mm3, 235 ± 35 mm3, and 107 ± 99 mm3. After 12 weeks, there was a significantly higher volume in group 2 compared to group 1 or 3 (P = .01, P = .04). Volumes between week 4 and week 12 were significantly lower in group 1 (P = .02), but not significantly different for groups 2 and 3 (P = .38, P = .74). Histologic evaluation revealed a robust lymphocytic infiltration in all cases as well as morphologic and immunophenotypic features suggestive of chondrogenic differentiation in a single animal.ConclusionsMicronized acellular dermis combined with stem cells and growth factors showed significantly less resorption 12 weeks after injection laryngoplasty compared to micronized acellular dermis alone. Groups using novel tissue‐engineered biomaterial showed a lower resorption rate over time compared with acellular dermis alone.Level of EvidenceNA. Laryngoscope, 128:160–167, 2018
