RESUMEN

Computer-aided design and computer-aided manufacturing and digitally simulated surgeries have revolutionized maxillomandibular reconstruction. In particular, this technology has increased the accuracy and facilitated the process of dental implantation in fibula free flaps. Despite the efficacy of virtual planning, there is a minor degree of translational difference between digital and intraoperative measurements, which may affect the precision of implant and fibula orientations. This is especially concerning during the last stage of fibula insetting, where the graft segments have the potential to roll, yaw, or pitch. The objective of this study is to describe an advanced prosthodontic technique that ensures the fibula grafts and implants remain in a restorable position during final insetting. We describe the technique and workflow of the implant-borne articulation splint through a case presentation and demonstrate results at 4 months postoperative and postradiotherapy. Given the degree of investment placed in virtual planning, free flap reconstruction, and endosteal implants, a technique that ensures optimal restorability of each implant is pivotal. Larger studies are still required to fully elucidate the cost-effectiveness and long-term results of the implant-borne articulation splint.

RESUMEN

PURPOSE: The aim of this systematic review is to compare the perioperative characteristics and outcomes of submental artery island flap (SAIF) to free tissue transfer (FTT) in head and neck reconstruction. MATERIALS AND METHODS: Screening and data extraction were done with Pubmed, Embase, and Web of Science databases by two independent authors to identify randomized and observational studies that compared patient outcomes for SAIF vs. FTT for reconstruction head and neck cancer ablative surgery. Data were pooled with random-effects meta-analysis to determine pooled difference in means (DM), absolute risk differences, and 95% confidence intervals (CI). Heterogeneity was assessed with the I-squared statistic. RESULTS: Initial query yielded 997 results, of which 7 studies met inclusion criteria. The pooled sample sizes for the SAIF and FTT cohorts were 155 and 198, respectively. SAIF reduced mean operative time by 193 min (95% CI -160 to -227), reduced hospital stay by 2.1 days (95% CI -0.9 to -3.4), and had a smaller flap area of 22.5cm2 (95% CI 6.5 to 38.4). SAIF had a 5% higher incidence of partial flap necrosis than FTT (95% CI, 1 to 10), but all other perioperative complications, including recurrence rate in malignant cases, were statistically comparable. CONCLUSIONS: The SAIF requires less operative time, hospital stay, and has comparable perioperative outcomes to FTT, but the area of flap harvest is significantly smaller. The findings of this study add to the growing body of evidence demonstrating the safety and reliability of SAIF in head and neck reconstruction.

RESUMEN

The "Jaw in a Day" (JIAD) technique, first described by Levine and colleagues, establishes immediate functional occlusion through a single-stage maxillomandibular reconstruction with concurrent implant placement and provisional prosthesis delivery. In this study, the authors describe 2 cases exemplifying the reconstructive principles of JIAD. One patient underwent mandibular reconstruction with the JIAD technique and another patient underwent JIAD with an optimized rapid sequence computer-aided design and computer-aided manufacturing (CAD-CAM) for composite maxillomandibular reconstruction. Immediate implant-borne prosthesis was fixated and all implants osseointegrated into the neomandible. Although the authors' patient outcomes are consistent with the literature, the published reports of JIAD remain limited, and further studies are required to assess the long-term functional and aesthetic outcomes as well as cost-effectiveness of this approach.

RESUMEN

Tracheoarterial fistula is a rare complication of tracheostomy with an incidence of less than 1%. Survival of this disease entity is low, and it likely results from a major open operation in a high-risk surgical group. In our review of the literature, a tracheoinnominate artery fistula is the most commonly reported arterial fistula. However, we present a rare case of tracheo-left subclavian artery fistula. We have identified 1 previous case of tracheo-left subclavian fistula as a source of massive tracheal bleeding. In our case report, we describe the successful management of this disease by endograft placement. Owing to its rarity, there are no guidelines on the management approach to tracheoarterial fistulas, but given the difficulty of controlling this problem via median sternotomy, the placement of a covered stent may be the best therapy. Initially, case reports showed a role for endograft placement as a temporizing measure, but the risk of infection may be sufficiently low to justify this approach as a definitive therapy. Upon a 6-month follow-up, our patient remains without recurrence of bleeding or infection, and computed tomography angiography of the chest with 3D reconstruction has shown patency of the endovascular stent with resolution of the associated pseudoaneurysm.

RESUMEN

PURPOSE: To assess the prognostic value of neutrophil-to-lymphocyte ratio (NLR) in patients with unresectable intermediate- or advanced-stage hepatocellular carcinoma (HCC) treated with yttrium-90 radioembolization (RE). MATERIALS AND METHODS: Retrospective chart review was performed for 176 patients with intermediate- or advanced-stage HCC treated with RE between August 2000 and November 2012. The appropriate NLR cutoff was determined by receiver operating characteristic curves. Demographic, clinical, radiographic, and pathologic parameters were compared between patients with a normal NLR (< 5) and those with an elevated NLR (≥ 5) before RE. Barcelona Clinic Liver Cancer (BCLC) stage-stratified univariate and multivariate analyses were conducted to determine variables associated with overall survival. RESULTS: Under univariate analyses, patients with a normal NLR were found to have longer survival than individuals with a high NLR in intermediate/advanced-disease and advanced-disease cohorts. A multivariate Cox proportional-hazards model in the advanced-disease group confirmed that elevated NLR, high α-fetoprotein level, and low albumin level were independent predictors of worse survival. CONCLUSIONS: This study provides stage-dependent evidence for the prognostic role of NLR in the radioembolized HCC cohort. Patients with BCLC stage C disease with elevated NLR may not derive benefit from RE, and other intervening modalities should be explored in this subpopulation.

RESUMEN

OBJECTIVE: To perform a matched comparison of surgical and postsurgical outcomes between our robotic and laparoscopic hepatic resection experience. BACKGROUND: The application of robotic technology and technique to liver surgery has grown. Robotic methods may have the potential to overcome certain laparoscopic disadvantages, but few studies have drawn a matched comparison of outcomes between robotic and laparoscopic liver resections. METHODS: Demographics, intraoperative variables, and postoperative outcomes among patients undergoing robotic (n = 57) and laparoscopic (n = 114) hepatic resections between November 2007 and December 2011 were reviewed. A 1:2 matched analysis was performed by individually matching patients in the robotic cohort to patients in the laparoscopic cohort based on demographics, comorbidities, performance status, and extent of liver resection. RESULTS: Matched patients undergoing robotic and laparoscopic liver resections displayed no significant differences in operative and postoperative outcomes as measured by blood loss, transfusion rate, R0 negative margin rate, postoperative peak bilirubin, postoperative intensive care unit admission rate, length of stay, and 90-day mortality. Patients undergoing robotic liver surgery had significantly longer operative times (median: 253 vs 199 minutes) and overall room times (median: 342 vs 262 minutes) compared with their laparoscopic counterparts. However, the robotic approach allowed for an increased percentage of major hepatectomies to be performed in a purely minimally invasive fashion (81% vs 7.1%, P < 0.05). CONCLUSIONS: This is the largest series comparing robotic to laparoscopic liver resections. Robotic and laparoscopic liver resection display similar safety and feasibility for hepatectomies. Although a greater proportion of robotic cases were completed in a totally minimally invasive manner, there were no significant benefits over laparoscopic techniques in operative outcomes.

RESUMEN

IMPORTANCE: Rhytidectomy, or face-lift surgery, is the mainstay of facial rejuvenation and is constantly evolving. There is continuous research to improve outcomes and minimize complications of this surgery. OBJECTIVE: To synthesize the updated techniques in rhytidectomy published during the past 5 years, including surgical technique, advances in anesthetic technique, minimally invasive techniques, and adjunctive procedures performed at the time of rhytidectomy. EVIDENCE REVIEW: On February 8, 2018, a literature search was performed of the PubMed and Cochrane databases using the search terms, face-lift or rhytidectomy and techniques. Articles published from February 8, 2013, to February 8, 2018, that related to techniques of facial rejuvenation in the lower one-third of the face by lifting and supporting tissue with 5 or more patients were included. Systematic reviews and primary literature were considered; narrative reviews, validation studies, and anatomic studies were eliminated. The initial search resulted in 604 articles after duplicates were removed. This was reduced to 84 articles after dual independent review screening. FINDINGS: Of the 84 articles included, 51 (61%) regarding techniques of face-lifting in the past 5 years pertained to soft-tissue techniques; 14 (17%) pertained to implants or adjunctive medications, such as tissue sealants; and 12 (14%) related to adjunctive techniques performed in addition to face-lifting, such as fat grafting, resurfacing, and liposuction. All studies found the techniques reported therein to be effective, with similar or fewer complications compared with the literature. However, according to the Oxford Centre for Evidence-Based Medicine criteria, the level of evidence of the studies was generally poor, because 45 of the studies (54%) were case series (level 4 of evidence). CONCLUSIONS AND RELEVANCE: Several new techniques have been explored for rhytidectomy or face-lift in the past 5 years, including soft-tissue techniques, introduction of implants or topical medications such as tissue sealants, and concomitant adjunctive techniques to enhance results. The overall quality of the evidence is poor, with most articles using case series with nonvalidated measures to evaluate outcomes. There is considerable room for improvement in the literature if additional studies using cohort designs and validated outcomes are performed to validate the quality of the techniques introduced during the past 5 years.

RESUMEN

OBJECTIVE: The aim of this systematic review is to compare the perioperative outcomes of robotic versus conventional neck dissection in patients with head and neck malignancy. METHODS: An electronic search of PubMed, Web of Science, and EMBASE databases was conducted. We included studies with direct comparisons of robotic and open neck dissections and performed dual, independent data extraction for primary outcomes of nodal yield, recurrence rate, subjective cosmetic assessment, operative time, length of stay, and rates of perioperative complications. Data were pooled using random effects meta-analysis to determine the standardized mean difference (SMD), absolute risk difference (RD), and 95% confidence intervals (CI). RESULTS: Eleven comparative studies comprising 225 robotic and 430 open neck dissections met the final selection criteria. All studies had low to moderate risk of bias. Robotic surgery improved cosmesis (SMD 1.15, 95% CI 0.73 to 1.56) but also increased operative time (SMD 1.94, 95% CI 1.25 to 2.63). Total nodal yield, pathological nodal yield, recurrence rate, rates of perioperative complications, and length of stay were not significantly different between the two groups, and the 95% CIs suggested that false negative results were unlikely. The results remained consistent after stratification by pathology and robotic technique. CONCLUSION: Although robotic neck dissection may offer similar perioperative outcomes compared to conventional neck dissection, it requires significantly more operative time. Whereas cosmesis was found to be superior among the robotic cohort, this must be viewed cautiously given the nonvalidated measurement tool that was used and the inherent reporting bias associated with it.

RESUMEN

OBJECTIVE: The aim of this systematic review is to compare the surgical outcomes of supraclavicular artery island flap (SCAIF) and free tissue transfer (FTT) in head and neck reconstruction. DATA SOURCES: PubMed, Web of Science, and EMBASE databases. REVIEW METHODS: Independent screening and data extraction were performed by 2 authors. Only studies that directly compared SCAIF and FTT were included. Data were pooled with random-effects meta-analysis to determine the standardized mean differences (SMDs), risk differences, and 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistics. The Methodological Index for Non-Randomized Studies tool was used to evaluate extent of bias in studies. RESULTS: The initial query yielded 661 results, of which 4 comparative studies remained for final analysis. The pooled sample sizes for the SCAIF and FTT cohorts were 100 and 84, respectively. SCAIF was associated with reduction of operative time by a large effect size (SMD, 1.65; 95% confidence interval, 0.78-2.52). The harvested flap areas and perioperative complications, including rates of total flap loss, partial flap necrosis, and recipient/donor site dehiscences, were comparable between the 2 procedures with low to high heterogeneity among studies. CONCLUSION: SCAIF requires less operative time and has comparable short-term perioperative results to FTT. The findings of this study support the viability of SCAIF as an alternative to FTT and provide evidence for its inclusion in the reconstructive armamentarium of major head and neck ablation and trauma.

RESUMEN

OBJECTIVE: Several surgical interventions are offered to patients with Ménière's disease (MD) who fail medical management. Although outcomes have historically been reported according to American Academy of Otolaryngology-Head and Neck Surgery guidelines, patient-reported outcome measures (PROMs) are increasingly used to evaluate treatments. This study reviews PROMs used to assess surgical treatments for MD and compares the effect of each intervention based on PROM scores. DATA SOURCES: PubMed, EMBASE, CINAHL, and Web of Science. REVIEW METHODS: This is a systematic review and meta-analysis of English-language studies that reported PROMs for surgical treatments of MD. Two independent investigators assessed study eligibility, rated the quality using Methodological Index for Non-Randomized Studies (MINORS), and abstracted data for comparative analysis. A random-effects model was used for meta-analysis of pooled data. RESULTS: Of 148 unique studies identified, 11 satisfied inclusion criteria. The Ménière's Disease Outcome Questionnaire (MDOQ) was the most commonly used survey. Interventions included intratympanic gentamicin, vestibular nerve section, endolymphatic sac surgery, and labyrinthectomy. Pooled analysis of 8 studies that used the MDOQ instrument demonstrated statistically significant improvements in quality of life but did not identify a difference between destructive and nondestructive procedures. CONCLUSION: Although our review shows significant improvements in PROM scores for both destructive and nondestructive interventions, there was no significant difference noted between treatment types. We cannot draw conclusions regarding the comparative effectiveness of specific interventions, and the results do not account for placebo effects or the natural history of the disease. Further investigation with randomized controlled trials should be considered in future studies.

RESUMEN

Objective To assist otolaryngologists in counseling patients with hoarseness who would benefit from injection laryngoplasty on whether or not to perform the procedure in the office vs the operating room. Data Sources Cochrane library, CINAHL, PubMed, and EMBASE. Review Methods Systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting standards of English-language articles that compared voice outcomes for in-office and in the operating room injection laryngoplasty. Two independent investigators assessed study eligibility, rated the quality using Methodological Index for Non-Randomized Studies (MINORS), and abstracted data for comparative analysis. Results Of 689 initial studies, 4 observational, comparative studies met inclusion criteria, with follow-up of 2 weeks to 12 months postinjection. Laryngoplasty was most commonly performed for vocal fold immobility with varied injectable materials (micronized dermis, hyaluronic acid, and calcium hydroxyapatite). Follow-up ranged from 2 weeks to 12 months. Voice outcomes improved in all studies, with comparable improvement for patients injected in the office vs the operating room ( P = .42 to P = .88). Meta-analysis of 3 studies showed no difference in Voice Handicap Index-10 voice outcomes by treatment setting (standardized mean difference -0.11, P = .441), with the 95% confidence interval (-0.405 to 0.176), making it unlikely that anything larger than a small or trivial difference was missed. Conclusion Our systematic review makes it unlikely that meaningful clinical differences exist in postprocedure voice outcomes for injection laryngoplasty in the office vs the operating room.

RESUMEN

Objective Up to 75% of patients with chronic rhinosinusitis (CRS) suffer with poor sleep quality and reduced quality of life. Endoscopic sinus surgery has demonstrated encouraging results in improving sleep function. The aim of this systematic review is to assess the change in sleep quality after surgery for CRS. Data Sources PubMed, Web of Science, EMBASE. Review Methods An electronic search was conducted with the keywords "sinusitis" or "rhinosinusitis" and "sleep." Studies were included only when adults underwent endoscopic sinus surgery and were evaluated pre- and postoperatively by the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), the Apnea-Hypopnea Index (AHI), the sleep domain of Sino-Nasal Outcome Test-22, or the sleep domain of Rhinosinusitis Disability Index. Results The database search yielded 1939 studies, of which 7 remained after dual-investigator screening. The standardized mean differences (95% CI) for the ESS, PSQI, and AHI were -0.94 (-1.63 to -0.26), -0.80 (-1.46 to -0.14), and -0.20 (-0.32 to -0.07), indicating large, moderate to large, and small improvements, respectively. All analyses displayed high heterogeneity ( I2 = 95%-99%). Conclusion Sleep quality, as measured by the ESS and PSQI surveys, shows substantial improvement after surgery for CRS, with smaller improvement seen for AHI. Generalizability of our results is limited by high heterogeneity among studies and by broad confidence intervals that cannot exclude small to trivial changes. The findings of this meta-analysis provide insight into the effect of CRS-related endoscopic sinus surgery on sleep quality, which should guide future research direction and counseling of patients in the clinical setting.

RESUMEN

Objective Evaluate if electrode design affects hearing preservation (HP) following cochlear implantation (CI) with full-length electrodes. Study Design Case series with chart review. Setting Tertiary referral academic center. Subjects and Methods Forty-five adults with low-frequency hearing (≤85 dB at 250 and 500 Hz) who underwent unilateral CI with full-length electrode arrays made by 1 manufacturer were included. HP was calculated with (1) mean low-frequency pure-tone average (LFPTA) at 250 and 500 Hz (MEAN method), (2) a percentile method across the audiometric frequency spectrum generating an S-value (HEARRING method), and (3) functional if hearing remained ≤85 dB at 250 and 500 Hz. Audiometric testing was performed approximately 1 month and 1 year postoperatively, yielding short-term and long-term results, respectively. Results Of 45 patients who underwent CI, 46.7% received lateral wall (LW) and 53.3% received perimodiolar (PM) electrodes. At short-term follow-up, LW electrodes were associated with significantly better HP than PM (LFPTA method: 27.7 vs 39.3 dB, P < .05; S-value method: 48.2 vs 21.8%, P < .05). In multivariate regression of short-term outcomes, LW electrode use was a significant predictor of better HP ( P < .05). At long-term follow-up, electrode type was not associated with HP. Younger patient age was the only significant predictor of long-term HP on multivariate analysis ( P < .05). Conclusion The LW electrode is associated with short-term HP, suggesting its design is favorable for limiting trauma to the cochlea during and directly following CI. Other factors, including age, are relevant for maintaining HP over the long term. The data support further investigation into what modifiable factors may promote long-term HP.
