Synchrony in head and neck surgery: Feasibility and outcomes of simultaneous scapular free flap reconstruction

Geometric Study and Clinical Case Series for Mandible Reconstruction With a Single-Piece Scapular Free Flap

BACKGROUND

Virtual surgical planning (VSP) with simple cutting templates could help surgeons preoperatively plan scapula reconstructions in the vertical and horizontal orientations.

METHODS

Virtually, eight defects were created in ten healthy mandibles and reconstructed with the subject-specific scapula vertically and horizontally. In the clinical series, 15 single-piece scapula mandible reconstructions planned with in-house VSP and guided with simple templates were compared with 15 freehand reconstructions.

RESULTS

Virtually, the vertical placement outperformed the horizontal placement in dice score (DSC) and Hausdorff-95 for all but one defect. Clinically, the VSP cohort had shorter operative time (386.6 ± 111.6 min vs. 268.9 ± 50.6 min, p = 0.002), fewer tracheostomies (73% vs. 15%, p = 0.002), lower length of hospital stay (16.6 ± 13.5 days vs. 12.2 ± 8.1 days, p = 0.319), and higher complete/partial union to a non-significant degree (78% vs. 100%, p = 0.471).

CONCLUSION

A single-piece scapula free flap is a versatile option for mandibular reconstruction. VSP has time and cost savings potential and quality of life impact that should be further investigated.

Donor site morbidity after scapula free flap surgery of head and neck reconstruction: A systematic review and meta-analysis

BACKGROUND

The scapula free flap is becoming increasingly more utilized in head and neck reconstruction due to its natural geometry and soft tissue versatility. This study reviews the incidence rate, risk factors, and treatments of complications of scapula donor site morbidity.

METHODS

A review was performed for articles published between October 1990 and November 2022 in Medline (OVID), PubMed, Web of Science, and CENTRAL. After screening, 24 articles meeting the criteria were included.

RESULTS

Overall, 660 head and neck surgeries with the scapula donor bone across 24 studies were included. Twenty studies of 612 scapula free flaps reported a pooled postoperative complication rate of 10.7%, with no major complications. Seven studies of 199 scapula reconstructions showed a mean Disability of Arm, Shoulder and Hand (DASH) score of 14.39/100.

CONCLUSION

With its low rate of morbidity, the scapula flap presents itself as a good alternative for patients at risk for poor healing.

Improving Operating Room Efficiency in Otolaryngology-Head and Neck Surgery: A Scoping Review

OBJECTIVE

One minute of operating room (OR) time costs $36 to 37. However, ORs are notoriously inefficient. There is growing literature on improving OR efficiency, but no formal review of this topic within otolaryngology has been performed. This study reviews and synthesizes the current literature on improving OR efficiency within otolaryngology.

DATA SOURCES

MEDLINE, EMBASE, Web of Science, CINAHL, Cochrane Library, preprints.org, and medRxiv were searched on November 4, 2022.

REVIEW METHODS

Published English studies were included if they reported on metrics for improving OR efficiency within otolaryngology. There were no publication date restrictions. Articles were screened by 2 reviewers. Preferred Reporting Items for Systematic Reviews and Meta-analysis reporting for scoping reviews was followed.

RESULTS

The search yielded 9316 no-duplicate articles; 129 articles were included. Most of the studies reported on head and neck procedures (n = 52/129). The main tactics included surgical considerations: hemostatic devices, techniques, and team/simultaneous approaches; anesthetic considerations: local anesthetic and laryngeal mask airways; procedure location considerations: procedures outside of the OR and remote technologies; standardization: equipment, checklists, and personnel; scheduling considerations: use of machine learning for booking, considering patient/surgeon factors, and utilizing dedicated OR time/multidisciplinary teams for on-call cases.

CONCLUSION

The current literature brings to attention numerous strategies for improving OR efficiency within otolaryngology. Applying these strategies and implementing novel techniques to manage surgical cases may assist in offloading overloaded health care systems and improving access to care while facilitating patient safety and outcomes. Anticipated barriers to implementation include resistance to change, funding, and the current strain on health care systems and providers.

The Complications of Osseous Reconstruction in the Head and Neck: A Systematic Review and Meta-analysis

OBJECTIVE

To compare the postoperative complications of the fibular free flap (FFF), scapula free flap (SFF), and osteocutaneous radial forearm free flap (OCRFFF) following osseous reconstruction in the head and neck.

DATA SOURCES

PUBMED, EMBASE, Cochrane.

REVIEW METHODS

A literature search and systematic review were performed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. A meta-analysis of proportions was conducted using a random effects model to compare operative time and postoperative complications.

RESULTS

The systematic review identified 26 studies comparing at least 1 variable of interest. The odds ratio estimates favored reduced rates of flap failure with the OCRFFF when compared to FFF (0.7, confidence interval [CI]: 0.29-1.11, P < .001), while FFF and SFF were similar. The mean difference estimates for operative time significantly favored FFF over SFF (-51.04 minutes, CI: -92.73 to -9.35, P = .016) and OCRFFF over FFF (66.77 minutes, CI: 52.74-80.8, P < .001). The FFF was more prone to hardware exposure, longer hospital stays, and donor site complications. Recipient wound complications and fistula rates were similar for all flap types.

CONCLUSION

Depending on the clinical context, the OCRFFF, FFF, and SFF are all robust options for reconstruction in the head and neck. The OCRFFF is associated with a reduced rate of flap failure and shorter operative times. The SFF requires longer operative times, although significant variation was observed between institutions. The FFF has broad reconstructive indications but is associated with more perioperative and long-term complications.

The versatility of the scapular free flap: A workhorse flap? A systematic review and meta-analysis

BACKGROUND

The scapular free flap (SFF) is essential in complex reconstructive surgery and often indicated in complex defects with compromised or poor local tissue integrity. This review aims to assess the versatility and reliability of the SFF during reconstruction.

METHODS

A comprehensive literature review of multiple databases was conducted following the PRISMA guidelines. An analysis of pooled data was performed to evaluate flap failure rate for any anatomical unit using SFF as the primary endpoints. Secondary endpoints included other complication rates after reconstruction such as partial flap loss, revision surgery, fistula, hematoma, and infection.

RESULTS

A total of 110 articles were included, with 1447 pooled flaps. The main recipient site was the head and neck region (89.0%). Major indications for reconstruction were malignancy (55.3%), burns (19.2%), and trauma (9.3%). The most common types of flaps were osteocutaneous (23.3%), cutaneous (22.6%), and chimeric (18.0%). The pooled flap failure rate was 2% (95%CI: 1%-4%). No significant heterogeneity was present across studies (Q statistic 20.2, p = .69; I2 .00%, p = .685). Nonscapular supplementary flaps and grafts were required in 61 cases. The average length and surface area of bone flaps were 7.2 cm and 24.8cm2, respectively. The average skin paddle area was 134.2cm2.

CONCLUSION

The SFF is a useful adjunct in the reconstructive surgeon's armamentarium as evidence by its intrinsic versatility and diverse clinical indications. Our data suggest a low failure rate in multicomponent defect reconstruction, especially in head and neck surgery. SFFs enable incorporation of multiple tissue types and customizable dimensions-both for vascularized bone and cutaneous skin-augmenting its value in the microsurgeon's repertoire as a chimeric flap. Further research is necessary to overcome the conventional barriers to SFF utilization and to better comprehend the specific scenarios in which the SFF can serve as the preferred alternative workhorse flap.

Virtual surgical planning for maxillary reconstruction with the scapular free flap: An evaluation of a simple cutting guide design

BACKGROUND

The study's objective is to assess the feasibility and utility of VSP for maxillary reconstruction with the scapular free flap.

METHODS

An open-source VSP platform was used to create the reconstruction models and simple guides. Clinical, operative, and postoperative data were collected.

RESULTS

Ten patients in the VSP cohort and 18 in the non-VSP control cohort were included in the study. There was a significant reduction in operative time (256.0 ± 69.4 vs. 448.1 ± 108.2 min, p < 0.01), tracheotomy rate (20% vs. 72%, p < 0.01), increased two-team utilization rate (80% vs. 0%, p < 0.01) and better reconstructive accuracy (7.5 ± 3.4 vs. 11.7 ± 7.6 mm, p = 0.048) for the VSP cohort.

CONCLUSIONS

Maxillary reconstruction planned with an in-house open-source VSP platform and accompanied simple guides can facilitate a two-team approach, reduce operative time, and improve structural accuracy. This open-source technology has great potential to be readily applied in other institutions to improve efficiency and outcomes.

Patient-reported outcomes and morbidity after head and neck reconstructions: An evaluation of fibular and scapular free flaps

BACKGROUND

Fibular (FFF) and scapular free flaps (SFF) are versatile tissue transfers for head and neck reconstruction. However, their relative morbidity has been sparsely studied. The primary goal of this study was to evaluate the morbidity and patient-reported outcome measures of these two reconstructive options.

MATERIALS AND METHODS

Case series of patients from 2017 to 2020 who underwent a FFF or SFF for head and neck ablation. Demographic and surgical outcome measures, such as Charlson Comorbidity Index (CCI), anesthetic time, donor site morbidity, and perioperative morbidity score (POMs) were extracted. Patients were contacted to complete the Decision Regret Scale (DRS), University of Washington Quality of Life (UW-QoL), Oral Health Impact-14, and limb specific functional outcome measures. Statistical analyses included a linear regression.

RESULTS

In total, 97 FFF (mean age 58.5, 62.9% male) and 55 SFF (mean age 64.8, 63.6% male) were included. Total surgical time was higher in the SFF group (p < 0.05) and they had more comorbidities (p < 0.01). SFF patients had lower POM scores on post-operative day three (p < 0.05) while FFF patients scored better on the UW-QoL Physical Domain (p < 0.01). The DRS for both groups (FFF mean DRS 22.7, SFF mean DRS 19.2) was similar. When adjusted for patient morbidity, however, the SFF group had less decisional regret (p < 0.05).

CONCLUSION

This is the largest comprehensive evaluation of patient-reported outcome measures for FFF and SFFs. SFFs required longer surgical times but had less early morbidity than FFFs. Patients who underwent either reconstructions reported mild decisional regret, proving these are generally well tolerated procedures.
