Analysis of cost and outcomes in bony versus soft tissue midface free flap reconstruction

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Outcomes and cost of soft tissue versus bony midface free flap reconstruction (MR) with and without virtual surgical planning (VSP) were evaluated.

Methods

Retrospective review of MR including ischemic time (IT), operative duration (OD), length of stay (LOS), and total cost (TC). Eighty-one soft tissue and 76 bony MR (VSP = 23) were reviewed.

Results

Bony MR was used for higher complexity defects (p = 0.003) and was associated with higher IT (p < 0.001), OD (p < 0.001), LOS (p = 0.032), and TC (p < 0.001). VSP was associated with a mean 111.2 ± 37.9 minute reduction in OD (p = 0.004) compared to non-VSP bony flaps. VSP was associated with higher itemized cost, but no increase in TC (p = 0.327).

Conclusions

Bony MR was used for higher complexity MR and was associated with increased TC, LOS, OD, and IT. VSP shortened OD with no significant increase in TC.

4-Hexylresorcinol (4HR) is a food additive and class I histone deacetylase inhibitor. In this study, we examined the effects of 4HR administration on the submandibular gland in a growing rat model.

Comparison between connective tissue graft and xenogeneic acellular dermal matrix to treat single gingival recession: A data reanalysis of randomized clinical trials

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objectives

There are few studies comparing xenogeneic acellular dermal matrixes (XDMs) with connective tissue graft (CTG) to treat single gingival recession (GR). The present study involved a reanalysis of previous studies and comparison of CTG or XDM to treat single RT1/GR.

Materials and methods

Fifty patients from three previous randomized clinical trials treated either by CTG (n = 25) or XDM (n = 25) were evaluated after 6-month. Clinical, patient-centered, and esthetic parameters were assessed. Pearson's correlation and regression analyses were also performed.

Results

Greater recession reduction (RecRed), percentage of root coverage (%RC), and complete root coverage (CRC) were observed in the CTG group (p ≤ 0.02). Gingival thickness (GT) and keratinized tissue width (KTW) gains were higher in the CTG group. The CTG group showed better esthetic at 6-month. Logistic analyses reported that GT([OR] = 1.6473) and papilla height (PH) (OR = 8.20) are predictors of CRC. GT*XDM interaction was a negative predictor of CRC (OR = 7.105−5). GT at baseline acted as a predictor of RecRed in both groups (p = 0.03). The XDM graft impacted RecRed and %RC negatively. Baseline PH was a predictor of %RC for both grafts.

Conclusion

CTG was superior for treating RT1/GR, providing better root coverage outcomes and tissue gains over time. GT, PH, and graft type were classified as predictors of CRC.

Clinical significance

CTG presented better outcomes to treat single RT1 gingival recession when compared to the XDM.

Intraoperative Redosing of Surgical Antibiotic Prophylaxis in Addition to Preoperative Prophylaxis Versus Single-dose Prophylaxis for the Prevention of Surgical Site Infection: A Meta-analysis and GRADE Recommendation

alexandrossfakianakis shared this article with you from Inoreader
imageObjective: The aim of this study was to determine the effect of preoperative surgical antibiotic prophylaxis (SAP) with additional intraoperative redosing compared to single-dose preoperative surgical antibiotic prophylaxis on the incidence of surgical site infections (SSI). Summary Background Data: Preoperative SAP is standard care for the prevention of SSI. During long surgical procedures, additional intraoperative redosing of SAP is advised, but there is great variability in redosing strategies and compliance rates. Methods: We performed a systematic search of MEDLINE (PubMed), Embase, CINAHL and CENTRAL on June 25th, 2021 according to PROSPERO registration CRD42021229035. We included studies that compared the effect of preoperative SAP with additional intraoperative redosing to single dose preoperative SAP (no redosing) on SSI incidence in patients undergoing any type of surgery. Two researchers performed data appraisal and extraction of summary data independently. Meta-analyses were stratified per study type. We used a generic inverse variance random-effects model to estimate a pooled odds ratio with corresponding 95% confidence intervals (CIs). Results: We included 2 randomized controlled trials (RCT) and 8 cohort studies comprising of 9470 patients. Pooled odds ratios for SSI in patients receiving intraoperative redosing compared to those without redosing were 0.47 (95% CI: 0.19–1.16. I2 = 36%) for RCTs and 0.55 (95% CI: 0.38–0.79, I2 = 56%) for observational cohorts. There was considerable clinical heterogeneity among antibiotics used and redosing protocols. GRADE-assessment showed overall low certainty of evidence. Conclusion: Intraoperative redosing of SAP may reduce incidence of SSI compared to a single dose preoperative SAP in any type of surgery, based on studies with considerable heterogeneity of antibiotic regimens and redosing protocols.

Amylase as a Diagnostic Tool for Plunging Ranula: Clinical Series and Description of the Technique

alexandrossfakianakis shared this article with you from Inoreader

Objectives

This study describes a technique of measurement for neck cyst amylase content and reviews the experience of a tertiary referral center for cases of suspected plunging ranula.

Methods

A retrospective study was performed at the Manukau Surgical Center in Auckland, New Zealand. Patients with a possible diagnosis of plunging ranula based on clinical presentation and diagnostic aspiration of the cyst contents were included. Demographic data, imaging and laboratory findings were collected, along with findings from surgery and histology. The technique for measuring the amylase of the aspirated cyst contents was also carefully recorded.

Results

The 37 cases of confirmed plunging ranula included in this study had a submandibular cystic swelling that was aspirated. Imaging features consistent with a plunging ranula were seen in 89% of the study group. All cases had detectable levels of amylase of ≥3 U/L in the ranula contents. There was large variability (range: 5–560 U/L) in the concentration of amylase, with 70% of the cases demonstrating an amylase concentration below 200 U/L. Aspirates were typically described as viscous (87.5%) and yellow or straw-colored.

Conclusion

The combination of clinical presentation, imaging and the presence of amylase in the cyst contents is diagnostic for plunging ranula.
