Background:
s/Aims: Early liver graft regeneration after living donor liver transplantation (LDLT) is critical for patient outcomes, yet prospective volumetric data from Indian recipients remain limited. This study quantifies early graft regeneration and identifies predictors using computed tomography (CT) volumetry.
Methods:
In this prospective single-center study, 34 consecutive adult LDLT recipients underwent CT volumetry on postoperative days 7 and 30.
Results:
Mean baseline graft volume was 607.9 ± 137.9 cm3 , increasing to 957.3 ± 175.7 cm3 at day 7 (+62%, p < 0.001) and 1,293.4 ± 247.0 cm3 at day 30 (+111%, p < 0.001), achieving 93% ± 22.7% of predicted standard liver volume (SLV). Multivariate analysis identified recipient body mass index (BMI) (β = 29.4 cm3 /kg/m2 , 95% CI 14.4–44.4, p < 0.001) and graft-to-recipient-weight ratio (GRWR) (β= 435.9 cm3 per unit, 95% CI 95–777, p = 0.015) as independent predictors of day-30 graft volume (adjusted R2 = 0.349). Left-lobe grafts showed higher proportional growth than right-lobe grafts (174% ± 41% vs. 103% ± 34%, p < 0.001) with comparable absolute volumes (p = 0.56). Younger recipients (19–41 years) demonstrated greater regeneration than older recipients (56–64 years; 160% ± 32% vs. 109% ± 38%, p = 0.01). Mild macrosteatosis (< 30%) did not impair regeneration.
Conclusions
Liver graft regeneration in this Indian LDLT cohort was rapid, with near-complete SLV restoration by 30 days. BMI and GRWR independently predicted volumetric recovery, supporting personalized graft selection and the expanded use of left-lobe grafts.

Archives of Craniofacial Surgery 2025;26(6):244-254
Background:
Cleft palate results from incomplete fusion of the palatine shelves during embryonic development and varies in severity. It affects speech, hearing, and feeding, often leading to complications such as nasal regurgitation and recurrent infections. The condition is common worldwide and frequently coexists with cleft lip. Surgery remains the primary treatment, aiming to restore both palatal length and function. In this study, Furlow’s double Z-plasty and von Langenbeck palatoplasty have been compared for their effectiveness in minimizing complications and improving outcomes.
Methods:
This study included 22 children aged 6 to 18 months with non-syndromic complete cleft palates, randomly assigned into two groups. Group A underwent von Langenbeck’s palatoplasty with intravelar veloplasty, while Group B underwent Furlow’s double opposing Z-plasty.
Results:
Preoperative palatal measurements were comparable between the two groups. Cleft width did not significantly affect surgical outcomes, and both techniques effectively achieved tension-free closure. Von Langenbeck’s repair with intravelar veloplasty was as effective as Furlow’s palatoplasty in achieving palatal lengthening, while offering the additional advantage of being an anatomically based repair associated with lower fistula rates.
Conclusion
Von Langenbeck’s repair with intravelar veloplasty is as effective as Furlow’s palatoplasty in achieving palatal lengthening and provides the advantage of an anatomically sound repair with a reduced fistula rate.

Neurospine 2024;21(1):253-260
Objective:
To evaluate preoperative disability’s influence on patient-reported outcomes (PROs) following surgery for degenerative spondylolisthesis (DS).
Methods:
DS patients who underwent surgical intervention were retrospectively identified from a single-surgeon spine registry. Cohorts based on Oswestry Disability Index (ODI) < 41 (milder disability) and ≥ 41 (severe disability) were created. Demographic differences were accounted for with 1:1 propensity score matching. For the matched sample, perioperative and PRO data were additionally collected. PROs assessed included mental health, physical function, pain, and disability. Pre- and up to 2-year postoperative PROs were utilized. Average time to final follow-up was 15.7 ± 8.8 months. Improvements in PROs and minimal clinically important difference (MCID) rates were calculated. Continuous variables were compared through Student t-test and categorical variables were compared through chi-square tests.
Results:
Altogether, 214 patients were included with 77 in the milder disability group. The severe disability group had worse postoperative day (POD) 1 pain scores and longer hospital stays (p ≤ 0.038, both). The severe disability group reported worse outcomes pre- and postoperatively (p < 0.011, all), but had greater average improvement in 12-item Short Form health survey mental composite score (SF-12 MCS), 9-Item Patient Health Questionnaire (PHQ-9), visual analogue scale (VAS)-back, and ODI by 6 weeks (p ≤ 0.037, all) and PHQ-9, VAS-back and ODI by final follow-up (p ≤ 0.015, all). The severe disability cohort was more likely to achieve MCID for SF-12 MCS, PHQ-9, and ODI (p ≤ 0.003, all).
Conclusion
Patients with greater baseline disability report higher POD 1 pain and discharge later than patients with milder disability. While these patients report inferior physical/mental health before and after surgery, they report greater improvements in mental health and disability postoperatively.

Objective:
To evaluate the effect of Veterans RAND 12-item health survey mental composite score (VR-12 MCS) on postoperative patient-reported outcome measures (PROMs) after undergoing lateral lumbar interbody fusion.
Methods:
Retrospective data from a single-surgeon database created 2 cohorts: patients with VR-12 MCS ≥ 50 or VR-12 MCS < 50. Preoperative, 6-week, and final follow-up (FF)- PROMs including VR-12 MCS/physical composite score (PCS), 12-item Short Form health survey (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), visual analogue scale (VAS)-back/leg pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected. ∆6-week and ∆FF-PROMs were calculated. Minimal clinically important difference (MCID) achievement rates were determined from established cutoffs from the literature. For intercohort comparison, chi-square analysis was used for categorical variables, and Student t-test for continuous variables.
Results:
Seventy-nine patients were included; 25 were in VR-12 MCS < 50. Mean postoperative follow-up time was 17.12 ± 8.43 months. The VR-12 MCS < 50 cohort had worse VR-12 PCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, and ODI scores preoperatively (p ≤ 0.014, all), worse VR-12 MCS/PCS, SF-12 MCS, PROMIS-PF, PHQ-9, and ODI scores at 6-week postoperatively (p ≤ 0.039, all), and worse VR-12 MCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, VAS-LP, and ODI scores at FF (p ≤ 0.046, all). The VR-12 MCS < 50 cohort showed greater improvement in VR-12 MCS and SF-12 MCS scores at 6 weeks and FF (p ≤ 0.005, all). The VR-12 MCS < 50 cohort experienced greater MCID achievement for VR-12 MCS, SF-12 MCS, and PHQ-9 (p ≤ 0.006, all).
Conclusion
VR-12 MCS < 50 yielded worse mental health, physical function, pain and disability postoperatively, yet reported greater improvements in magnitude and MCID achievement for mental health.
