Cupid's Bow Leveling and Preservation of Lip Height and Width: A Modified Rotation-Advancement Technique.

BACKGROUND: Several methods for cleft lip repair have been developed over time, with no clear method considered the standard. In the authors' department, the use of a modified rotation-advancement technique rather than the traditional rotation-advancement technique in unilateral complete cleft lip repair has increased over the past decade. This study aimed to determine which technique provides better outcomes. METHODS: This retrospective study was conducted by analyzing the preoperative and postoperative aesthetic nasal and labial anthropometric measurements of the frontal and basal views of 213 consecutive patients treated between October of 2013 and June of 2019. A total of 141 participants were treated with the traditional rotation-advancement technique, and 72 with the modified rotation-advancement technique. The inclusion criteria were nonsyndromic unilateral complete cleft lip repair with high-resolution, good-quality photographs; no presurgical nasoalveolar molding; no revision in the lip or nose areas; and at least 1 year of follow-up. RESULT: Patients who received the modified rotation-advancement technique had significantly improved Cupid's bow position and orientation ( P < 0.02 and P < 0.01, respectively) and enhanced vertical lip height symmetry ( P < 0.01) while preserving the lip width. The columellar length ( P < 0.03) and angulation ( P < 0.045) were also significantly improved, with enhanced nostril inclination in this group ( P < 0.06). CONCLUSIONS: According to the findings of the current study, modified rotation-advancement technique assisted surgeons in improving symmetrical leveling of the Cupid's bow and significantly aided in correcting lip height without compromising lip width. Moreover, the modified rotation-advancement technique resulted in better aesthetic nasal outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Evidence and mechanism by which upper partial fibulectomy improves knee biomechanics and decreases knee pain of osteoarthritis.

To investigate the change in short-term clinical outcomes and biomechanical properties of the knee in response to upper partial fibulectomy and to probe into the biomechanical mechanism underlying the clinical benefits of upper partial fibulectomy for medial compartment knee osteoarthritis (KOA). A total of 29 patients with medial compartment KOA underwent upper partial fibulectomy. Visual analog scale (VAS) pain, the hospital for special surgery knee score (HSS), hip-knee-ankle (HKA) angle (measured in the frontal plane), and flexion/extension range of motion of the knee were assessed before and up to 6 months after surgery. Patients and 20 healthy controls were evaluated by 3D gait analysis and dynamic lower limb musculoskeletal analysis. Both VAS pain and HSS score were significantly improved (p < 0.001) one day after surgery and steadily improved during the subsequent 6 months. HKA angle improved (p = 0.025) immediately and remained stable by 3 months after surgery. The decreased overall peak KAM (decreased by 11.1%) and increased HKA angle (increased by 1.80 degrees from a more varus to more neutral alignment) of affected and operated side by 6 months after surgery were observed. Muscle activity of biceps femoris caput longum of affected and operated side increased immediately and was equivalent to healthy controls by 6 months after surgery (p = 0.007). This pilot study provides biomechanical evidence of benefit from partial upper fibulectomy and indicates a plausible rationale for the improvement in clinical symptoms. Long-term clinical outcomes and precise biomechanical mechanism of partial upper fibulectomy should be further investigated. © 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
