1. Functional Reconstruction of Abdominal Wall in Prune Belly Syndrome Using Vastus Lateralis Muscle Flaps: A Prospective Observational Study.
This prospective observational study describes a bilateral, innervated vastus lateralis musculo-fascial flap transfer to reconstruct the anterior abdominal wall in Prune Belly Syndrome. EMG confirmed dynamic contractions with improved core function and symptoms linked to inadequate intra-abdominal pressure, representing the first reproducible functional reanimation of the abdominal wall in PBS.
Impact: It pioneers a physiologically dynamic reconstruction for a previously unsolved functional deficit in PBS, shifting focus from cosmetic contouring to true muscle function with objective EMG validation.
Clinical Implications: Offers a functional reconstructive option for PBS that can restore cough, defecation, and postural control by re-establishing intra-abdominal pressure; may influence surgical planning and long-term rehabilitation strategies in pediatric reconstructive surgery.
Key Findings
- Introduces bilateral pedicled, innervated vastus lateralis musculo-fascial flaps transposed to the anterior abdominal wall.
- Anchoring to the costal arch and pubic symphysis recreates the rectus abdominis functional vector enabling dynamic contraction.
- EMG and motor testing confirmed active muscle contraction with improved core function.
- Symptoms related to low intra-abdominal pressure (e.g., constipation, respiratory infections) were reduced.
Methodological Strengths
- Prospective observational design with objective EMG assessment of muscle activity.
- Physiologically grounded anchoring and reanimation concept with functional outcome measures.
Limitations
- Sample size and exact follow-up duration not specified; likely small due to rarity.
- No comparator group or randomized control to isolate effect size.
Future Directions: Define patient selection criteria, quantify donor-site morbidity, standardize rehabilitation, and validate durability and quality-of-life gains in multicenter prospective cohorts.
Prune Belly Syndrome (PBS) is a rare congenital disorder characterized by severe abdominal wall muscle deficiency, leading to significant impairment of respiratory, urinary, and gastrointestinal function. Despite numerous reconstructive attempts, no technique has achieved full functional restoration of the anterior abdominal wall. This paper introduces a novel dynamic reconstructive approach using bilateral pedicled musculo-fascial Vastus Lateralis (VL) flaps for functional abdominal wall reconstruction in PBS. Unlike traditional abdominoplasty-based procedures that mainly address cosmetic deformity, this method focuses on restoring true muscle dynamics and physiological function. The technique involves harvesting innervated, vascularized VL flaps from both thighs and transposing them to the anterior abdominal wall through a subcutaneous tunnel while preserving their neurovascular pedicles. The muscles are anchored to the costal arch superiorly and the pubic symphysis inferiorly, effectively recreating the functional vector of the rectus abdominis. This configuration enables dynamic contraction of the abdominal wall and reinstates the ability to generate intra-abdominal pressure required for coughing, defecation, and postural control. Follow-up assessment, including electromyography (EMG) and motor testing, confirmed active muscle contraction and marked improvement in core function. Patients demonstrated restored abdominal wall activity, enhanced motor abilities, and reduced symptoms related to ineffective intra-abdominal pressure, such as constipation and respiratory infections. This study presents the first reproducible surgical solution achieving both anatomical reconstruction and functional reanimation of the abdominal wall in PBS. The described technique offers a transformative step in pediatric reconstructive surgery, combining microsurgical precision with physiological restoration to improve long-term quality of life.
2. Comparison of efficacy and safety of fractional 1064 nm picosecond laser and low-fluence Q-switched Nd:YAG laser in the treatment of melasma.
In 99 women with melasma, fractional 1064 nm picosecond Nd:YAG achieved greater and faster mMASI reductions than low-fluence Q-switched Nd:YAG with comparable rates of post-inflammatory hyperpigmentation. PSNY also required lower fluence, supporting it as an efficient, safe alternative.
Impact: Provides head-to-head comparative effectiveness and safety data for two widely used laser modalities in melasma, informing device selection and treatment planning.
Clinical Implications: Supports preferential use of fractional 1064 nm picosecond Nd:YAG for faster improvement at lower fluence, with similar risk of post-inflammatory hyperpigmentation; may guide counseling and protocol optimization.
Key Findings
- PSNY achieved mean mMASI reductions of 23.7% after 2 sessions and 40.7% after 5 sessions.
- QSNY achieved mean mMASI reductions of 9.8% after 2 sessions and 29.5% after 5 sessions.
- Post-inflammatory hyperpigmentation occurred in 7.4% (PSNY) vs 13.3% (QSNY) without significant difference.
- PSNY required lower energy fluence to achieve improvements.
Methodological Strengths
- Direct comparative analysis of two treatment modalities with a standardized outcome (mMASI).
- Multiple treatment sessions with consistent follow-up time points.
Limitations
- Retrospective design without randomization introduces selection bias.
- All participants were female; short-term follow-up limits durability assessment.
Future Directions: Prospective, randomized trials with diverse populations and longer follow-up to assess durability, optimal parameters, and recurrence.
Melasma is a persistent and recurrent condition that remains difficult to manage effectively. Both fractional 1064 nm picosecond Nd:YAG (PSNY) and low-fluence Q-switched Nd:YAG (QSNY) lasers have been applied in treatment, yet there is currently insufficient data to compare their efficacy and safety. This retrospective study evaluated 99 female patients with melasma, including 54 treated with PSNY laser and 45 with QSNY laser. Each patient received two to five laser sessions at 2-4-week intervals. Clinical efficacy was evaluated by the modified Melasma Area and Severity Index (mMASI) at baseline, as well as four weeks following the second and fifth treatment sessions, with adverse events carefully documented. The PSNY laser produced a mean mMASI reduction of 23.7% and 40.7% after two and five sessions, respectively, while QSNY treatment achieved reductions of 9.8% and 29.5%. Although both modalities were safe and effective, PSNY laser demonstrated faster clinical improvement and required lower energy fluence. Post-inflammatory hyperpigmentation occurred in 7.4% of PSNY-treated patients and 13.3% of QSNY-treated patients, with no significant difference between groups. In conclusion, fractional PSNY laser therapy provides a rapid, safe, and effective alternative to QSNY laser for managing melasma.
3. A Partial-Incision Modification of the Jones Procedure for Involutional Entropion: A Retrospective Study.
A retrospective series of 46 eyelids treated with a partial-incision modification of the Jones procedure achieved complete symptom resolution, 4.3% recurrence, and no major complications, while preserving eyelid anatomy. The technique sutures pretarsal OOM to lower eyelid retractors without disrupting the tarsus or lateral canthus.
Impact: Demonstrates a simplified, cosmetically favorable, and safe alternative for involutional entropion with low recurrence, informing oculoplastic practice.
Clinical Implications: Provides a minimally invasive option that preserves critical anatomy, minimizes visible scarring, and achieves low recurrence; may be favored for elderly patients prioritizing cosmesis and function.
Key Findings
- Retrospective series of 46 eyelids with at least 6 months follow-up.
- Complete resolution of symptoms with 4.3% (2 eyelids) recurrence.
- No ectropion, punctum displacement, or lower eyelid retraction observed.
- Technique preserves tarsus and lateral canthus while suturing pretarsal OOM to lower eyelid retractors.
Methodological Strengths
- Clear procedural description enabling reproducibility.
- Systematic follow-up with clinically meaningful outcomes and complication reporting.
Limitations
- Retrospective design without control group limits causal inference.
- Single-center with modest sample size may limit generalizability.
Future Directions: Prospective comparative studies to benchmark against standard Jones and other techniques, with longer-term recurrence, cosmesis, and patient-reported outcomes.
PURPOSE: To evaluate the efficacy and safety of a modified Jones procedure using a partial-incision technique for the correction of involutional entropion. METHODS: This retrospective study included 46 eyelids from 36 elderly patients with involutional entropion. A lateral partial-incision was made to access the lower eyelid retractors without disrupting the tarsal plate or lateral canthus. The pretarsal orbicularis oculi muscle (OOM) was sutured to the lower eyelid retractor with 6-0 Vicryl sutures to correct vertical laxity and improve lid position. Operative outcomes, recurrence, complications, and patient satisfaction were recorded. Patients were followed for at least 6 months. RESULTS: All patients achieved satisfactory aesthetic and functional outcomes, with complete resolution of preoperative symptoms. Only 2 eyelids (4.3%) experienced recurrence during long-term follow-up. No cases of ectropion, punctum displacement, or lower eyelid retraction were observed. Intraoperative findings revealed retractor thinning without disinsertion in all cases. CONCLUSION: This modified Jones procedure offers a safe, minimally invasive, and cosmetically favorable alternative for the treatment of involutional entropion. It simplifies surgical steps, preserves critical eyelid anatomy, and results in favorable outcomes with low recurrence and complication rates.
