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.
BACKGROUND: Tongue-tie (ankyloglossia) is a congenital tongue anomaly that may be associated with speech articulation defects, impacting social integration and self-confidence in affected children. Intervention is aimed at improving functional speech outcomes and potentially mitigating orofacial developmental disturbances. Ankyloglossia has also been implicated in altering upper airway anatomy due to its restrictive nature. PURPOSE: The primary objective was to compare the effectiveness of z-plasty closure versus linear closure following lingual frenuloplasty in improving speech articulation. The secondary objective was to assess changes in oropharyngeal airway volume following surgical correction. STUDY DESIGN, SETTING, AND SAMPLE: This was a prospective randomized controlled study conducted at the dedicated cleft and craniofacial surgery unit of a tertiary academic center. Subjects were children with Kotlow Grade III/IV ankyloglossia and documented speech articulation defects, with exclusion criteria including developmental delay, syndromic diagnoses, or cleft lip/palate. PREDICTOR VARIABLE: The predictor variable was the surgical technique used post-lingual frenuloplasty:z-plasty closure or linear closure. OUTCOME VARIABLES: The primary outcome was speech articulation, which was measured using the percentage of correct vowels and consonants (PCVC) and speech intelligibility (SI) scores. The secondary outcome was change in oropharyngeal airway volume, as quantified by cone beam computed tomography (CBCT). COVARIATES: The covariates were age and sex. RESULTS: There was no significant difference in age (z-plasty: 6.46 ± 2.16 years vs linear closure: 6.80 ± 2.04 years; P = .6) or sex distribution (male/female: 8/7 vs 9/6; P = .7) between groups. Postoperatively, the z-plasty group demonstrated significantly greater improvement in percentage of correct vowels and consonants (mean change: 26.47 ± 2.94 vs 17.26 ± 2.18; P < .001) and SI scores (mean change: 2.06 ± 0.45 vs 1.2 ± 0.67; P < .001). Both groups showed increased oropharyngeal airway volume, with a larger mean percentage increase in the z-plasty group (12.11 ± 2.33% vs 10.43 ± 1.47%; P = .026). CONCLUSION AND RELEVANCE: Lingual frenuloplasty using z-plasty closure yields superior speech articulation outcomes and a greater increase in oropharyngeal airway volume compared to linear closure, likely attributable to enhanced tissue mobilization and reduced contracture. These findings support z-plasty as the preferred surgical approach for functional rehabilitation in ankyloglossia.
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.
Total endoscopic video-assisted mitral valve replacement represents a comparatively new advancement in cardiac surgery. It is associated with cosmetic benefits, minimal pain, and shorter hospital stay than right anterolateral thoracotomy approach of minimally invasive mitral valve replacement. Our study aims to delineate the advantages and disadvantages of these two minimally invasive techniques along with the relative improvement of quality of life. In this prospective randomized study, 40 patients undergoing isolated mitral valve replacement via right anterolateral thoracotomy approach (group A) and 40 patients undergoing the same procedure using the totally endoscopic method (group B) were randomly selected. Immediate postoperative outcomes, including duration of intensive care unit and hospital stay, were analyzed. Additionally, outcomes were assessed at 1 and 6 weeks, 6 months, and 1 year. Group B exhibited significantly lower pain scores (
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.
To evaluate the safety and efficacy of microwave ablation (MWA) in treating benign thyroid nodules and any advantage of modified hydrodissection (MHD) techniques while performing these procedures. This retrospective study included 76 consecutive patients treated for benign thyroid nodules using MWA. Patients were divided into 2 groups. Group 1 included patients treated before November 2019 using the hydrodissection technique (n = 38), and group 2 included patients treated using the MHD technique after November 2019 (n = 38). Hydrodissection-MHD was performed using 5% dextrose. A portable MWA device with a 2450 MHz frequency was used as the generator. MWA antennas with internal water-cooled units and temperature monitoring features with a 16G diameter, 100 cm body length, and 3 mm tip length were used for MWA procedures. Color Doppler ultrasound examinations, thyroid function tests, volume reduction ratios, Visual Analog Scales, and Cosmetic Scores were performed on the patients in the first, third, sixth, and every sixth months after ablation procedures. Complications and procedure times were also recorded. No significant differences in volume reduction ratios, Visual Analog Scale, or Cosmetic Score were observed between the groups at 3, 6, and 12 months. Lower complication rates ( 26.31% vs 7.89%, P = 0.03) and procedure times (10.30 vs 7.30 min; P = 0.04) were observed with the MHD technique. There were no residual or recurrent nodules or thyroid hormone deficiencies during the follow-up. MWA of benign thyroid nodules is safe and effective. Using the MHD technique lowers complication rates and procedure time.
