Summary
Three clinically oriented studies highlight how procedural choices can optimize both function and cosmetic outcomes. A pediatric RCT shows z‑plasty closure after lingual frenuloplasty significantly improves speech metrics and airway volume versus linear closure; a cardiac RCT suggests totally endoscopic mitral valve replacement reduces postoperative pain with cosmetic advantages; and a retrospective thyroid study shows modified hydrodissection lowers microwave ablation complications and procedure time without sacrificing efficacy.
Research Themes
- Technique optimization to balance functional outcomes and cosmesis
- Minimally invasive surgery with patient-centered recovery benefits
- Image-guided ablation procedural refinements to improve safety

1. Comparative Evaluation of Z-Plasty and Linear Closure in Ankyloglossia Patients: A Randomized Study of Effects on Speech Articulation and Airway Volume.
In a randomized pediatric trial of Kotlow Grade III/IV ankyloglossia, z-plasty closure after lingual frenuloplasty produced significantly greater gains in percentage of correct vowels and consonants and speech intelligibility than linear closure. Both groups increased oropharyngeal airway volume, with a larger percentage increase in the z-plasty group.
Impact: This RCT provides high-level evidence favoring z-plasty closure to optimize functional speech outcomes and airway metrics, directly informing surgical technique selection.
Clinical Implications: Surgeons should consider z-plasty closure following lingual frenuloplasty to maximize speech gains and airway volume improvements, and incorporate these data into shared decision-making with families.
Key Findings
- Z-plasty yielded larger PCVC improvement than linear closure (26.47 ± 2.94 vs 17.26 ± 2.18; P < .001).
- Speech intelligibility improvement was greater with z-plasty (2.06 ± 0.45 vs 1.2 ± 0.67; P < .001).
- Both groups increased oropharyngeal airway volume; z-plasty showed a larger mean percentage increase (12.11 ± 2.33% vs 10.43 ± 1.47%; P = .026).
Methodological Strengths
- Prospective randomized controlled design with balanced baseline demographics
- Objective outcomes including CBCT-based airway volume and validated speech metrics (PCVC, SI)
Limitations
- Single-center study with a relatively small sample size (n=30)
- Long-term durability and real-world functional outcomes beyond the postoperative period are not detailed in the abstract
Future Directions: Larger multicenter RCTs with longer follow-up should assess durability, impacts on feeding, sleep-disordered breathing, and patient-reported outcomes.
2. Outcomes following totally endoscopic mitral valve replacement versus mitral valve replacement through right thoracotomy: a prospective randomized controlled study.
In an 80-patient randomized trial comparing totally endoscopic video-assisted mitral valve replacement with right anterolateral thoracotomy, the endoscopic group showed significantly lower postoperative pain scores. Outcomes including ICU and hospital stay and patient follow-up assessments were conducted up to 1 year.
Impact: Provides randomized evidence that a totally endoscopic approach can reduce postoperative pain while offering cosmetic advantages, informing surgical strategy for eligible patients.
Clinical Implications: For appropriate candidates and experienced centers, totally endoscopic MVR may reduce postoperative pain and improve cosmetic outcomes; perioperative pathways should incorporate pain management and recovery protocols tailored to this approach.
Key Findings
- Prospective randomized comparison of totally endoscopic MVR (n=40) vs right anterolateral thoracotomy MVR (n=40).
- Endoscopic group had significantly lower postoperative pain scores (as reported in the abstract).
- Outcomes were analyzed immediately postoperatively and at 1 and 6 weeks, 6 months, and 1 year.
Methodological Strengths
- Randomized controlled design with predefined follow-up timepoints up to 1 year
- Comparative evaluation of two minimally invasive techniques relevant to patient-centered outcomes
Limitations
- Abstract provides limited quantitative detail beyond pain reduction; effect sizes for other endpoints are not stated
- Single-country setting and potential learning-curve effects may limit generalizability
Future Directions: Report detailed quantitative outcomes (LOS, ICU time, complications), conduct multicenter RCTs, and evaluate cost-effectiveness and patient-reported cosmetic outcomes.
3. Microwave Ablation of Benign Thyroid Nodules: The Importance of Modified Hydrodissection.
In a retrospective cohort of 76 patients undergoing microwave ablation for benign thyroid nodules, adopting modified hydrodissection reduced complication rates and procedure time versus conventional hydrodissection, with comparable volume reduction, pain, and cosmetic scores over follow-up. No recurrences, residual nodules, or thyroid hormone deficiencies were observed.
Impact: Demonstrates a simple procedural modification that improves safety and efficiency of thyroid MWA without compromising efficacy or cosmetic outcomes, relevant to interventional radiology practice.
Clinical Implications: When performing thyroid MWA, consider modified hydrodissection with 5% dextrose to reduce complications and procedure time while maintaining clinical and cosmetic outcomes.
Key Findings
- Retrospective comparison of conventional hydrodissection (n=38) vs modified hydrodissection (n=38) in 76 consecutive MWA cases.
- Modified hydrodissection reduced complications (26.31% vs 7.89%; P = 0.03).
- Procedure time was shorter with modified hydrodissection (10.30 vs 7.30 minutes; P = 0.04).
- Volume reduction ratios, VAS pain scores, and Cosmetic Scores were similar between groups at 3, 6, and 12 months.
- No residual/recurrent nodules or thyroid hormone deficiencies during follow-up.
Methodological Strengths
- Consecutive series with standardized device parameters and temperature monitoring
- Multiple follow-up assessments including imaging, thyroid labs, VAS, and cosmetic scores
Limitations
- Retrospective, non-randomized design with potential temporal and selection biases
- Single-center study with modest sample size; generalizability may be limited
Future Directions: Prospective randomized studies should validate safety gains, and cost-effectiveness analyses could quantify the value of modified hydrodissection.
