ObjectiveThe purpose of this prospective and randomized clinical study was to assess differences in patient morbidity between minimally invasive lateral sinus elevation (study group, n = 14) and conventional one-stage lateral sinus elevation (control group, n = 12). It was hypothesized that trauma to soft tissue was reduced in the study group.Materials and methodsOptical 3-D imaging was assessed blinded on days 1 and 7 after surgery to determine the visible soft tissue swelling of the upper lip and cheeks. Postoperative pain and discomfort were evaluated by a visual analogue scale (VAS; scale 0–10).ResultsImmediately and on day 1 after surgery, the study group patients rated pain and discomfort as 2.4 [SD 1.7] and 3.1 [SD 2.1], respectively, on the VAS; while, the controls rated 4 [SD 1.6] and 5.6 [SD 1.7], respectively. The mean facial soft tissue volume change, assessed on day 1 after surgery, was 5.0 cm3 [range: 0.2–9.2] for the study group and 15.5 cm3 (9.3–21.55) for the controls (p = 0.00).ConclusionsDespite the small number of patients in this prospective study, 3-D based minimally invasive one-stage lateral sinus elevation resulted in favourable patient morbidity with less postoperative visible facial soft tissue volume changes.
