Purpose: To illustrate variations of the vascular anatomy of the subscapular system highlighting practical implications on surgical access, patient positioning, and strategies to maximize the exposure of vascular pedicle., Methods: A retrospective review of patients undergoing reconstruction with a scapular tip free flap over a 2-year period at a tertiary referral center., Results: Forty patients were included. In 25 (62.5%) cases, the thoracodorsal artery (TD) ended bifurcating into latissimus dorsi (LD) and angular branch (AB), with the serratus artery branch arising from the LD pedicle; this vascular pattern was defined as "LD-dominant." In 10 (25%) cases, the TD bifurcated into LD and AB, with the serratus artery branch arising from the latter vessel, defined as "AB-dominant." Lastly, there was a trifurcation pattern in 5 (12.5%) patients. There was considerable variability in the distal branching pattern. Twenty-two (55%) patients had 2 LD branches; in 11 (27.5%) cases, there was only 1 LD branch, and 7 (17.5%) cases had 3. Thirty-seven patients (92.5%) had 1 AB; in the remaining three cases (7.5%), there were 2. The entry point of AB was located 4.86 cm (mean) ± 0.75 cm from the fibrous tip. The arm positioning and scapular retraction were the key maneuvers to facilitate pedicle exposure and dissection, with the shoulder abducted and scapula retracted away from the body., Conclusion: The subscapular vascular anatomy is highly variable. Knowledge of anatomic variability alongside surgical pearls to harvest STFF could facilitate the introduction of this flap into the toolkit of head and neck reconstructive teams., (© 2022.

Objectives/hypothesis: Free flap transfer offers a versatile option for reconstruction in head and neck surgery, with success rates over 95%. There remains a substantial re-exploration rate of roughly 5% to 15%, with early recognition of compromise essential to flap survival. Monitoring techniques are highly desirable, with the gold standard being clinical monitoring. The Cook-Swartz Doppler (CSD) probe utilizes Doppler technology to inform clinicians about real-time flow. We aim to describe our adoption of this technology in 100 consecutive free flaps., Study Design: Prospective case series., Methods: Prospective data were collected from July 2014 to June 2015 on 100 consecutive free flaps performed at a head and neck unit in London, Ontario. All patients had a CSD inserted for arterial and venous monitoring., Results: A total of 100 free flaps were performed on 99 patients. Sensitivity was 87.1% and specificity was 85.7%. Positive predictive value was 98.8% and negative predictive value was 33.3%. False-negative and false-positive rate were 1.0% and 12.0%, respectively. The exploration rate was 12%, with no flap loss and two partial debridements. The CSD was helpful in management in 9% of cases and was clinically unhelpful in 11% of cases, with 10 of 11 abnormal signals ignored. There were three unique CSD complications; one retained wire, one pedicle laceration during extraction, and one clot around the probe interrupting signal., Conclusions: The CSD is a helpful adjunct to clinical monitoring but has unique complications, which were not previously described. Pros and cons must be considered for new centers adopting this technology., Level of Evidence: 4 Laryngoscope, 131:E1854-E1859, 2021., (© 2021 American Laryngological, Rhinological and Otological Society Inc, "The Triological Society" and American Laryngological Association (ALA).)

Background: The scapular system free flap has been increasing in popularity to reconstruct short segment mandibular bony defects. It is important to assess donor site morbidities systematically., Methods: Prospective cohort study using objective measures of range of motion (ROM) and shoulder strength were measured. Subjective disability was evaluated with validated questionnaires-Neck Disability Impairment Index and Shoulder Pain and Disability Index., Results: Twenty-six patients were recruited-19 with scapular tip and 7 with lateral border scapular free flap. Decreased ROM on the operated side was noted for shoulder abduction, shoulder flexion, and external rotation. No significant difference was noted for shoulder extension. Strength was reduced for shoulder flexion, shoulder abduction, and external rotation. Subjective measurements did not indicate significant shoulder function disruption., Conclusion: Patients with scapular free flap reconstruction did not experience significant shoulder morbidity. Measures of shoulder ROM and power were objectively affected; however, subjective measures of shoulder disability were not significantly affected., (© 2019 Wiley Periodicals, Inc.)

Background: The scapular tip free flap (STFF) is becoming more popular for oromandibular reconstruction. This article reviewed the early and late outcomes in a larger series over 9 years., Methods: We conducted a retrospective review of all consecutive patients who underwent oromandibular reconstruction using the STFF at London Health Sciences Centre. Demographic information, surgical data, and complications were collected and analyzed., Results: From April 2008 to March 2017, 81 STFFs were performed in 80 patients. The average bony reconstruction measured 5.4 cm. Bone-only flaps were utilized in 24 cases (29.6%). Five cases (6.2%) required a single osteotomy. There were 3 (3.7%) flap failures. There were 7 plate extrusions and 11 cases of radiographic nonunion., Conclusion: The STFF is a reliable option with acceptable early and long-term results. The STFF may be considered as a first line option especially for shorter bone defects or in conjunction with complex soft tissue requirements., (© 2018 Wiley Periodicals, Inc.)

Purpose of Review: The current article reviews the most recent publications of computer-assisted reconstruction using bony free flaps, emphasizing on comparative reports using these novel techniques., Recent Findings: Computer-aided reconstruction has shown some benefits in comparison with traditional techniques and some of the perceived limitations are currently being addressed in the latest reports. Still, there is a lack of appropriate comparative studies and unblinded measurements to establish solid conclusions., Summary: Despite the application of new technologies showed encouraging results, it is premature to state that the traditional technique should be replaced by the modern approaches.

Objectives: Plate extrusions after free tissue transfer for mandibular reconstruction can be problematic and generally require revision surgery. Our objective was to assess the predictors of plate extrusion and compare outcomes between fibular free flaps (FFF), lateral border scapular flaps (LBSF), and scapular tip free flaps (STFF)., Methods: Retrospective review of consecutive patients who underwent osseous free tissue reconstruction of the mandible (2008-2014) at Victoria Hospital, London, Ontario. Patient demographics and treatment-related information were collected., Results: We identified 134 procedures and 27 (20.2%) plate extrusions (21/61 FFF, 3/49 STFF, and 3/24 LBSF). Freedom from extrusion after 2 years was significantly associated with the use of FFF (P = .003, HR 6.09 1.82-20.44), performing 1 osteotomy (P = .03, HR 2.61 1.08-6.31), and anterior mandibular defects (P = .01, HR 2.66 1.25-5.66) in the univariate model. FFF's were employed more frequently in younger patients, with 2.4 mm plates, more anterior defects, and with a greater number of osteotomies (P < .001). However, after controlling for these variables in multivariate analyses the use of a FFF was the only significant predictor of extrusion at 2 years (P = .006, HR 3.68 1.46-9.28)., Conclusions: At our institution, use of the STFF predicts mandibular defects that are less prone to developing plate extrusion and FFF tended to be used more frequently in anterior defects with osteotomies. However, after controlling for these factors use of the FFF appeared to have higher rates of extrusion than scapular flaps. Further prospective studies controlling for defect variables are needed to elucidate the risk factors for plate extrusion., (© 2018 Wiley Periodicals, Inc.)

Background: The purpose of this study was to review our experience with the scapular tip free flap for mandibular reconstruction, describe the surgical approach, and highlight specific clinical applications., Methods: A retrospective review of all patients undergoing oromandibular reconstruction using a scapular tip free flap at the London Health Sciences Centre was undertaken. Patient demographics, surgical data, and early outcomes were collated., Results: Twenty patients were identified. The majority involved mandibular angle and short segment defects (16 of 20). Average length of the segmental defect was 6.2 cm with the longest measuring 8 cm. A single patient required an osteotomy. Six were revision cases. No vein grafts were required. One complete flap failure occurred., Conclusions: The natural scapular angle makes the scapular tip flap ideal for mandibular angle reconstruction. Short bone segments can be harvested with little donor-site morbidity. The long pedicle length may obviate vein grafts., (Copyright © 2012 Wiley Periodicals, Inc.)

Importance: Provides an approach to osseous free flap selection for reconstruction of segmental mandible defects that takes into consideration general medical status of the patient and reconstruction requirements; demonstrates the complementary qualities of fibular and subscapular system free flaps; and describes the different surgical indications for lateral border scapular and scapular tip free flaps., Objectives: To review our experience with osseous mandible reconstruction comparing the fibular and subscapular system free flaps, determine reconstruction-specific and general health variables that may differ between these patient groups, and present our approach to oromandibular reconstruction., Design: Retrospective study., Setting: Academic tertiary care medical center., Participants: A total of 110 patients (68 male, 42 female) undergoing single-stage oromandibular reconstructions with free-tissue transfers between May 1, 2006, and May 30, 2012., Intervention: Single-stage oromandibular reconstruction with free-tissue transfer., Main Outcome Measures: Differences in patient demographics, bone and soft-tissue aspects of the reconstruction, operative time, flap outcomes, and major postoperative complications between fibular, lateral scapular border, and scapular tip free flaps., Results: A total of 110 patients underwent 113 reconstructions, including 58 fibular free flaps (FFFs) (51.3%) and 55 subscapular system flaps (48.7%). Of the subscapular system free flaps, 27 flaps (49%) were scapular tip free flaps (STFFs) based on the angular artery branch of the thoracodorsal pedicle; the remaining 28 cases were lateral scapular border flaps (LSBFs). Patients undergoing reconstruction with FFFs were significantly younger than their subscapular system flap counterparts (56 vs 70 years, P < .001). Mean mandible defect lengths were similar for patients undergoing FFF and LSBF reconstruction (7.8 and 7.7 cm, respectively); STFFs were used to reconstruct significantly shorter defects (mean, 6.0 cm, P < .001). The FFFs were more commonly used for anterior mandible defects in which multiple osteotomies and limited soft tissue were required, while subscapular flaps were more commonly used for linear mandible defects with complex soft-tissue requirements. A single complete flap loss occurred in a patient who underwent reconstruction with an STFF; other complication rates were similar between groups., Conclusions and Relevance: The FFFs and subscapular flaps are complementary options for oromandibular reconstruction. The FFF is ideal for younger patients, extended defects, multiple osteotomies, and limited soft-tissue requirements. The subscapular system free flaps (LSBF and STFF) are excellent options for (1) elderly patients; (2) those with significant comorbidities, such as peripheral vascular disease; and (3) mandible defects associated with complex soft-tissue requirements. Furthermore, the STFF offers a reliable option to reconstruct short-segment defects, in particular, defects involving the angle of the mandible.
