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 novel bilateral pedicled, innervated vastus lateralis musculo-fascial flap transfer to recreate rectus abdominis dynamics in Prune Belly Syndrome. Electromyography confirmed active contraction with improved core function, enabling intra-abdominal pressure for coughing, defecation, and posture, and reducing constipation and respiratory infections.
Impact: Represents the first reproducible dynamic abdominal wall reanimation in PBS with objective functional verification. It could reshape pediatric reconstructive paradigms beyond cosmetic correction to true physiological restoration.
Clinical Implications: Offers a functional alternative to abdominoplasty-based reconstructions in PBS, emphasizing restoration of abdominal wall dynamics. Multidisciplinary planning should consider donor-site morbidity, growth, and long-term respiratory, gastrointestinal, and urologic outcomes.
Key Findings
- Bilateral pedicled, innervated vastus lateralis flaps recreated the rectus abdominis vector and enabled dynamic abdominal wall contraction.
- Electromyography and motor testing confirmed active muscle reinnervation with improved core function and intra-abdominal pressure generation.
- Patients showed reduced symptoms related to inadequate abdominal pressure (e.g., constipation, respiratory infections) and improved motor capabilities.
Methodological Strengths
- Prospective observational design with objective functional assessments (EMG, motor testing).
- Physiologic reconstruction using innervated, vascularized muscle preserving neurovascular pedicles.
Limitations
- Sample size and exact follow-up duration were not reported; likely small single-center series.
- No control group or standardized comparator; long-term durability and donor-site outcomes remain to be established.
Future Directions: Conduct multicenter prospective cohorts with standardized functional endpoints, quantify respiratory/GI/urologic outcomes, compare against abdominoplasty-based reconstructions, and evaluate long-term growth adaptation and donor-site morbidity.
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 a retrospective cohort of 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 safety and lower required fluence. Both modalities were effective, but PSNY provided a more rapid clinical response.
Impact: Direct head-to-head comparative data inform practical laser selection for melasma, addressing a common clinical dilemma with objective outcomes.
Clinical Implications: Fractional 1064 nm picosecond Nd:YAG may be preferred when rapid improvement is desired, using lower fluence while monitoring for post-inflammatory hyperpigmentation. Treatment plans should still individualize session numbers and intervals.
Key Findings
- PSNY achieved mean mMASI reductions of 23.7% after two sessions and 40.7% after five sessions.
- QSNY achieved mean mMASI reductions of 9.8% after two sessions and 29.5% after five sessions.
- Post-inflammatory hyperpigmentation occurred in 7.4% (PSNY) vs 13.3% (QSNY) without significant difference; PSNY required lower fluence.
Methodological Strengths
- Direct comparative groups with objective mMASI scoring and documented adverse events.
- Treatment intervals standardized (2–4 weeks) with assessment at defined timepoints.
Limitations
- Retrospective design without randomization; potential selection and confounding biases.
- All participants were female; short follow-up limited to weeks after sessions; energy parameters not fully standardized.
Future Directions: Prospective randomized trials comparing PSNY vs QSNY with standardized protocols, longer follow-up for relapse and PIH, and inclusion of diverse skin types.
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 undergoing a partial-incision modification of the Jones procedure achieved complete symptom resolution with a 4.3% recurrence rate and no major eyelid malposition complications. The technique preserves key anatomy, is minimally invasive, and yields favorable cosmetic and functional outcomes.
Impact: Provides a simplified, anatomy-preserving alternative to traditional approaches for involutional entropion with low recurrence and complication rates, emphasizing cosmetic outcomes.
Clinical Implications: Surgeons may adopt this partial-incision modification to minimize scarring and anatomical disruption while maintaining low recurrence. Patient counseling can emphasize both functional relief and cosmetically favorable results.
Key Findings
- Complete resolution of preoperative symptoms with satisfactory cosmetic and functional outcomes in all patients.
- Low recurrence rate of 4.3% (2 eyelids) over at least 6 months of follow-up.
- No ectropion, punctum displacement, or lower eyelid retraction; intraoperatively, retractors were thinned but not disinserted.
Methodological Strengths
- Clear surgical description with standardized key steps and preservation of critical anatomy.
- Systematic documentation of outcomes, complications, and patient satisfaction with minimum 6-month follow-up.
Limitations
- Retrospective single-center case series without a comparator limits causal inference.
- Modest sample size; longer-term durability beyond 6 months not established.
Future Directions: Prospective comparative studies versus other entropion techniques, longer follow-up to assess recurrence and cosmesis, and evaluation across diverse patient anatomies.
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.
