Objects: Anterior cervical plating decreases the risk of pseudarthrosis, increases rate of fusion following anterior cervical discectomy and fusion (ACDF). Dysphagia is a common complication of ACDF, with the anterior plate implicated as a potential contributor. A zero-prole, stand-alone interbody spacer has been postulated to minimize soft-tissue irritation and postoperative dysphagia, but studies are limited. We are reporting our ndings in term of clinico-radiological outcomes following the use of such devices in the treatment of cervical spine degenerative diseases with a focus on the course of postoperative prevertebral soft-tissue thickness and the incidence of dysphagia. The authors conducted a prospective analysis of all Methods: patients who had undergone ACDF between December 2018 and December 2019. All patients received a Zero-P implant (DePuy Synthes Spine).The Neck Disability Index (NDI),Modied Japanese Orthopaedic Association Score(mJOA) and visual analog scale (VAS) scores for arm and neck pain were documented. Dysphagia was determined using the Bazaz criteria. Prevertebral soft-tissue thickness, spinal alignment, intervertebral disc height were assessed as well. The nal outcome was assessed with Odom's criteria. Total 30 patients Results: were studied prospectively, and data were collected and analyzed. 17 male and 13 female consecutive patients, with a mean age of 48.28 ± 8.17 years, underwent ACDF with Zero-Prole spacer (42 total operated levels) in the dened study period. There were signicant improvements in neck and arm VAS scores, the NDI and mJOA scores following surgery at last follow up. The neck VAS score improved from a mean 7.34 ±1.87 to 1.04 ± 0.09 (p<0.01) . The arm VAS score improved from 7.22±2.03 to1.03±0.10 at latest follow up. NDI score improved signicantly from preoperative 31.94±6.73 to 12.87±5.24 and mJOAscore improved from preoperative 9.53±1.98 to 15.6±1.26 at last follow up. Immediate postoperative dysphagia was experienced by 36.67% of all patients. Complete resolution of dysphagia was demonstrated at the latest follow-up. Prevertebral soft-tissue thickness at postoperative 48 hrs decreased across all levels from a mean of 15.87 ±0.69 to 11.81 ± 0.53 mm at last follow up. Cervical alignment and intervertebral disc height were also improved signicantly after surgery. Radiographic fusion was achieved in 100% of implants. No correlation was found between prevertebral soft-tissue thickness and Bazaz dysphagia score. Majority of the patients had excellent outcomes in odom's criteria. Conclusions: Zero-Prole device is a safe and effective alternative for the treatment of cervical degenerative diseases. Chronic dysphagia rates are comparable to or better than those for previously published case series.

Object Anterior cervical plating decreases the risk of pseudarthrosis following anterior cervical discectomy and fusion (ACDF). Dysphagia is a common complication of ACDF, with the anterior plate implicated as a potential contributor. A zero-profile, stand-alone polyetheretherketone (PEEK) interbody spacer has been postulated to minimize soft-tissue irritation and postoperative dysphagia, but studies are limited. The object of the present study was to determine the clinical and radiological outcomes for patients who underwent ACDF using a zero-profile integrated plate and spacer device, with a focus on the course of postoperative prevertebral soft-tissue thickness and the incidence of dysphagia. Methods Using a surgical database, the authors conducted a retrospective analysis of all patients who had undergone ACDF between August 2008 and October 2011. All patients received a Zero-P implant (DePuy Synthes Spine). The Neck Disability Index (NDI) and visual analog scale (VAS) scores for arm and neck pain were documented. Dysphagia was determined using the Bazaz criteria. Prevertebral soft-tissue thickness, spinal alignment, and subsidence were assessed as well. Results Twenty-two male and 19 female consecutive patients, with a mean age of 58.4 ± 14.68, underwent ACDF (66 total operated levels) in the defined study period. The mean clinical follow-up in 36 patients was 18.6 ± 9.93 months. Radiological outcome in 37 patients was assessed at a mean follow-up of 9.76 months (range 7.2–19.7 months). There were significant improvements in neck and arm VAS scores and the NDI following surgery. The neck VAS score improved from a median of 6 (range 0–10) to 0 (range 0–8; p < 0.001). The arm VAS score improved from a median of 2 (range 0–10) to 0 (range 0–7; p = 0.006). Immediate postoperative dysphagia was experienced by 58.4% of all patients. Complete resolution was demonstrated in 87.8% of affected patients at the latest follow-up. The overall median Bazaz score decreased from 1 (range 0–3) immediately postoperatively to 0 (range 0–2; p < 0.001) at the latest follow-up. Prevertebral soft-tissue thickness significantly decreased across all levels from a mean of 15.8 ± 4.38 mm to 10.1 ± 2.93 mm. Postoperative lordosis was maintained at the latest follow-up. Mean subsidence from the immediate postoperative to the latest follow-up was 4.1 ± 4.7 mm (p < 0.001). Radiographic fusion was achieved in 92.6% of implants. No correlation was found between prevertebral soft-tissue thickness and Bazaz dysphagia score. Conclusions A zero-profile integrated plate and spacer device for ACDF surgery produces clinical and radiological outcomes that are comparable to those for nonintegrated plate and spacer constructs. Chronic dysphagia rates are comparable to or better than those for previously published case series.

The Impact

Objective: To evaluate the impact of soft tissue thickness (STT) on root coverage achieved with different periodontal plastic surgery procedures. Background: Gingival recession has been managed successfully through various surgical approaches, with great variability in outcomes. Anatomic characteristics of the recipient site and selected technique account in part for this variability. Gingival flap thickness is one of the most critical site-related characteristics. Methods: An electronic search was conducted on the major databases (PubMed, Embase, Web of Science). Human prospective studies with at least 6 mo of follow-up and with a numeric baseline measurement for gingival thickness were eligible. Only studies including nonsmoking patients were considered. Variables included surgical approach, participant characteristics, local anatomic factors, and follow-up time. Primary outcome was mean percentage root coverage (%RC) achieved, and complete root coverage was a secondary outcome. Results: A total of 42 studies were included (35 randomized controlled trials, 5 case series, 1 prospective cohort study, and 1 controlled clinical trial). Across studies, the pooled %RC was 81.9% (95% CI, 79.1% to 84.7%). The %RC was not significantly associated ( P = 0.267) with baseline soft tissue thickness; however there was a significant ( P = 0.031) inverse relationship between STT and %RC after 12-mo follow-up. Subgroup analysis showed that for no graft, there was a significant ( P = 0.025) positive relationship between STT and %RC with the exclusion of the single outlier study based on STT. Conclusions: STT plays a limited role in predicting root coverage across all approaches; when flaps are performed with no graft, the effect of STT is most critical. The length of time following surgery appears to influence outcomes, with 12-mo follow-up offering greater insight. Knowledge Transfer Statement: The results of this study can suggest to clinicians which periodontal plastic surgery technique to employ when treating challenging cases. In particular, it can be helpful when selecting the treatment approach to treat thin phenotype sites. This study could help clinicians provide a more appropriate treatment decision in such cases.

Nineteen fingertip amputations with exposed bone were treated with a semi-occlusive dressing. The quantity and quality of the regenerated soft tissue was examined. In all 19 fingers there was sufficient uncomplicated healing such that secondary surgical procedures were not needed. At follow-up 6–18 months after the injury, soft tissue thickness around the bone of the distal phalanx measured 6.0 mm (SD 1.6) on the palmar aspect (opposite side 7.0 mm (SD 0.8)) and 4.2 mm (SD 1.7) distally (opposite side 4.5 mm (SD 0.8)). The two-point discrimination was 4 mm (SD 2) (opposite side 3 mm (SD 1)). The skin healed almost without scarring and the dermal ridges reformed. The regeneration of the soft tissue thickness to almost 90% of its former extent is higher than we expected.

Objective:  This study aimed to determine the prevertebral soft tissue thickness among normal patients aged 0-14 years old in a tertiary government training hospital, to compare these values with divergent criteria in the standard otorhinolaryngology and radiology texts used in our institution, and to recommend adoption of a set of criteria based on the results.  Methods Study Design:  Descriptive Study Setting: Tertiary Government Hospital  Subjects and Methods:  Lateral cervical radiographs taken from May 2007 to August 2009 which were initially read as normal were collected.   Fifty (50) patients, 39 males and 11 females, aged 0-14 years old meeting inclusion criteria were reviewed and prevertebral soft tissue thicknesses (PVST) and cervical vertebral body diameter at levels C2, C5, C6 were measured and compared to criteria set by standard otorhinolaryngology and radiology textbooks.  Results:  The average PVST at C2 ranged from 4.02 mm for 2–3 year-olds (n= 2) to 8.16 mm for 1 –2 year-olds (n=2).   The average PVST at C5 ranged from 8.11mm for 1–2 year-olds to 10.75 mm for for 0-1 year-olds. The average PVST at C6 ranged from 7.13 mm for 1 – 2 year-olds to 10.36 mm for  0-1 year-olds. Only 12% of the patients satisfied the criteria set by Keats and Lusted, while 100% satisfied Duncan’s criteria, 94% and 98% satisfied Wippold’s 1st and 2nd criteria respectively.  Conclusion: All of the PVST criteria mentioned in Cummings’ Textbook of Otorhinolaryngology Head and Neck Surgery had a more than 90% accuracy compared to only 12% for those mentioned in Keats and Lusted’s Atlas of Roentgenographic Measurement.  Therefore, we recommend the use of any criteria for  PVST contained in the former over the latter.  Keywords:  Prevertebral soft tissue thickness, cervical vertebra
