Scapular Tip Free Flap for Head and Neck Reconstruction

Perioperative pain management after scapular tip free flap harvesting for head and neck reconstruction using mini-catheters to inject the local anesthetic

PURPOSE

Although functional and esthetic results after the use of a scapular tip free flap (STFF) in head and neck reconstruction, and the related donor-site morbidity, have been extensively described, data regarding acute postoperative donor-site pain management are lacking. Purpose of this study is to explore the use of mini-catheters to administer local anesthetics for donor-site pain management after reconstruction using STFF.

METHODS

Patients who underwent head and neck reconstruction using a STFF were prospectively enrolled and, through a perineural catheter placed in the donor site during the surgical procedure, a bolus of chirochaine was injected before the patient regained consciousness and at 8, 16, and 24 h postoperatively. Before and 40 min after each dose administration, donor-site pain on a numerical rating scale (NRS; 0-10) was evaluated.

RESULTS

Study population consisted of 20 patients (40-88 years). At 8 h, the pain scores before and after the injection were 0-10 (mean 3.35) and 0-5 (mean 1.25), respectively. At 16 h, the pain scores before and after the injection were 0-8 (mean 2.55) and 0-4 (mean 0.55), respectively. At 24 h, the pain scores before and after the injection were 0-8 (mean 1.30) and 0-4 (mean 0.30), respectively.

CONCLUSION

Statistical analysis confirmed a significant difference between the pain scores before and after administration at 8, 16, and 24 h (p < 0.001, p < 0.001, and p = 0.003, respectively). Mini-catheters for local anesthetic administration represent an effective strategy for pain control after STFF harvesting for head and neck reconstruction.

Use of scapular tip flaps in the reconstruction of head and neck defects: a systematic review and meta-analysis

Scapular tip flaps (STF) may be used as an alternative to traditional methods of reconstruction of head and neck cancer (HNC) defects. This study aimed to establish the success and complication rates for STF in HNC reconstruction. A literature search was conducted on PubMed, BMJ Journals, DARE, EMBASE databases and Cochrane (CENTRAL) register. (Registry CRD42023428012). A total of 23 studies fulfilled the inclusion criteria with 474 patients who underwent reconstructive procedures using the STF. 100% of STF used were free flaps (STFFs). The most common reason for reconstruction was following malignancy (81.4%, n = 386). The pooled success rates in all studies using scapular tip flaps in head and neck reconstruction was 99% (95% CI, 97 to 100, p = 1.00; I2 = 0). Pooled total complication rates were 38% (95% CI, 25 to 51, p < 0.01; I2 = 90%). 19.6% required return to theatre with only 1.5% being for repeat flap coverage. The STF demonstrated an overall success rate of 99%. This is higher than other documented success rates with mainstay flaps for HNC defect reconstruction. Complication and re-operation rates were also like recorded rates. This review demonstrates the advantage of STF as a safe and versatile reconstructive option for HNC related defects. Evaluation of the literature is limited by poor-quality studies and comparability bias.

Stacked fibula flap for unilateral total maxillectomy reconstruction with orbital preservation

Unilateral total maxillectomy is indicated for locally advanced maxillary tumors that require complete removal of the midface bony structure and inferior orbital rim. Reconstruction of this defect is challenging due to aesthetic and functional concerns. A retrospective review of patients at two tertiary-care institutions undergoing unilateral total maxillectomy reconstruction with a stacked fibula flap from 2018 to 2022 was performed. Each patient's clinical course was reviewed, and attention was focused on the demonstration of surgical steps with photos. Twenty patients underwent stacked fibula flap reconstruction for unilateral total maxillectomy orbital preservation defects. Surgical extirpation was performed for malignancy (80%, 16/20) and for osteoradionecrosis or benign tumor in 20% (4/20). The complication rate was 30% (6/20). Most flaps survived (95%, 19/20). We present a modified, reproducible method of fibula flap reconstruction for unilateral total maxillectomy with orbital preservation that only requires two segments and maintains positive aesthetic and functional results.

Assessment of micromotion at the bone-bone interface after coracoid and scapular-spine bone-block augmentation for the reconstruction of critical anterior glenoid bone loss-a biomechanical cadaver study

BACKGROUND

Glenoid bone loss is among the most important risk factors for recurrent anterior shoulder instability, and a bony reconstruction is recommended in cases of critical bone loss (> 15%). The commonly used surgical techniques, including coracoid transfer, are associated with considerable complications. The aim of this study was to assess the motion at the glenoid-bone-block interface after coracoid and spina-scapula bone-block reconstruction of the anterior glenoid.

METHODS

Twelve cadaveric shoulders were tested. A 20% bone defect of the anterior glenoid was created, and the specimens were randomly assigned for glenoid augmentation using a coracoid bone block (n = 6) or a scapular spine bone block (n = 6). The glenoid-bone interface was cyclically loaded for 5000 cycles with a force of 170 N. The micromotion was tracked using an optical measurement system (GOM ARMIS) and was evaluated with the GOM Correlate Pro software.

RESULTS

The most dominant motion component was medial irreversible displacement for the spina-scapula (1.87 mm; SD: 1.11 mm) and coracoid bone blocks (0.91 mm; SD: 0.29 mm) (n.s.). The most medial irreversible displacement took place during the first nine cycles. The inferior reversible displacement was significantly greater for spina-scapula bone blocks (0.28 mm, SD: 0.16 mm) compared to coracoid bone blocks (0.06 mm, SD: 0.10 mm) (p = 0.02).

CONCLUSIONS

The medial irreversible displacement is the dominant motion component in a bone-block reconstruction after a critical bone loss of the anterior glenoid. The spina-scapula and coracoid bone blocks are comparable in terms of primary stability and extent of motion. Thus, spina-scapula bone blocks may serve as alternatives in bony glenoid reconstruction from a biomechanical point of view.

Osseointegration and Bone Resorption of Scapula Tip Free Flaps in Mandibular Reconstruction

OBJECTIVES

Bone resorption of more conventional vascularized bone grafts have been well described showing minimal resorption over time. Few studies have evaluated osseous union and bone resorption in scapula tip free flaps (STFF) in the reconstruction of mandibulectomy defects. We aimed to describe our series on STFF with respect to osseous union and bone resorption over time.

METHODS

Retrospective chart review of patients receiving STFF from January 2014-January 2017 (n = 25). A neuroradiologist analyzed follow-up CT scans to assess (1) STFF complete, partial, or no osseous union with native mandible and (2) STFF volume change over time in a subset with multiple follow-up scans (n = 18).

RESULTS

Twenty-three of 25 patients (92%) showed complete or partial STFF osseous union with native mandible either distally or proximally. STFF volume change ranged from +4.8 to -54% (median -0.5%) over median follow-up interval of 23 months. History of chemoradiation therapy, bisphophonate use, sex, age, or smoking history did not correlate with bone resorption.

CONCLUSIONS

STFFs shows high rates of osseous union and limited bone resorption that is equivalent to, or less than, vascularized fibular and iliac crest flaps. Clinically, this translates into both optimal healing and functional and cosmetic outcomes, especially in the setting of prior therapies.

Mandibular reconstruction in head and neck cancer: which is the gold standard?

INTRODUCTION

The aim of this study is to perform a systematic review to compare the outcomes of the different surgical options for mandibular reconstruction in head and neck cancer.

MATERIAL AND METHODS

93 articles were selected. Four groups were identified: titanium plate without flaps, titanium plate covered by soft tissue flap, bone tissue flaps and double flaps. We compared patients' characteristics, site of mandibulectomy, type of reconstruction and complications.

RESULTS

4697 patients were reported. The groups were not homogeneous regarding the type of defect and the treatment history. A significant difference in terms of post-operative complications was found between group 1 and group 2 (p < 0.00001), and between group 2 and group 3 (p < 0.00001). Total complications rate for group 4 was significantly higher when compared to group 3 (p < 0.00001), but no significant difference was found with group 2.

CONCLUSION

These results suggest that mandibular reconstruction using a microvascular bone flap is the best surgical option in patients without significant comorbidities.

Comparing donor site morbidity in osteocutaneous radial forearm versus fibula free flap for mandibular reconstruction

PURPOSE

The osteocutaneous radial forearm free flap has gained popularity as a less morbid option for oromandibular reconstruction compared to the fibular free flap. However, there is a paucity of data regarding direct outcome comparison between these techniques.

METHODS

Retrospective chart review of 94 patients who underwent maxillomandibular reconstruction intervened from July 2012-October 2020 at the University of Arkansas for Medical Sciences. All other bony free flaps were excluded. Endpoints retrieved encompassed demographics, surgical outcomes, perioperative data, and donor site morbidity. Continuous data points were analyzed using independent sample t-Tests. Qualitative data was analyzed using Chi-Square tests to determine significance. Ordinal variables were tested using the Mann-Whitney U test.

RESULTS

The cohort was equally male and female, with a mean age of 62.6 years. There were 21 and 73 patients in the osteocutaneous radial forearm free flap and fibular free flap cohorts, respectively. Excluding age, the groups were otherwise comparable, including tobacco use, and ASA classification. Bony defect (OC-RFFF = 7.9 cm, FFF = 9.4 cm, p = 0.021) and skin paddle (OC-RFFF = 54.6 cm2, FFF = 72.21 cm2, p = 0.045) size were larger in the fibular free flap group. However, no significant difference was found between cohorts with respect to skin graft. There was no statistically significant difference between cohorts regarding the rate of donor site infection, tourniquet time, ischemia time, total operative time, blood transfusion, or length of hospital stay.

CONCLUSIONS

No significant difference in perioperative donor site morbidity was found between patients undergoing fibular forearm free flap and osteocutaneous radial forearm flap for maxillomandibular reconstruction. Osteocutaneous radial forearm flap performance was associated with significantly older age, which may represent a selection bias.

Tenants of Mandibular Reconstruction in Segmental Defects

The premises of mandibular reconstruction are the restoration of occlusion and mandibular contour for the purpose of preserving the facial identity, oral airway, and effective speech and mastication. Establishing functional occlusion is the primary tenant in all mandibular reconstruction. In cases of segmental defects, particularly in dentate regions of the mandible, there has been a paradigm shift over the past two decades in how surgeons are approaching the restoration of load-bearing mandibular continuity with capacity for dental implantation. Here we discuss considerations for deciding the most effective method of reconstruction in segmental defects.

A Modified Technique for Harvesting Scapular Tip Flap and to Allow 2 Teams to Work at the Same Time

AIM

The main aim of the present report is to describe a modified technique of tip scapular flap harvesting to allow 2 surgical teams to work at the same time and to shorten surgical times.

MATERIALS AND METHODS

The medical records of 25 patients that had undergone maxillary or mandibular reconstruction by using a free scapular tip flap were retrospectively reviewed to identify the possible advantages and disadvantages of this type of flap.

RESULTS

Thirteen patients analyzed in this series underwent maxillary reconstruction with tip scapular flap, while the other 12 patients underwent mandibular reconstruction. No failures, partial failures, or infections were evidenced in this series. Scapular tip flap allowed for acceptable esthetic and functional outcomes. In all cases, the patient was placed supine. No major complications were observed at the donor site during follow-up.

CONCLUSION

Scapular tip flap might be extremely useful for head and neck reconstruction. Pedicle length, versatility, and reliability represent the major advantages of this reconstructive recourse. Moreover, the resistance of the scapular vascular system to atherosclerosis could be helpful in patients showing contraindications to free fibula flaps.

Donor Site Morbidity and Quality of Life after Microvascular Head and Neck Reconstruction with a Chimeric, Thoracodorsal, Perforator-Scapular Flap Based on the Angular Artery (TDAP-Scap-aa Flap)

Extensive defects in the head and neck area often require the use of advanced free flap reconstruction techniques. In this study, the thoracodorsal perforator-scapular free flap technique based on the angular artery (TDAP-Scap-aa flap) was postoperatively evaluated regarding the quality of life and the donor site morbidity using the standardized SF-36 and DASH questionnaires (short form health 36 and disabilities of the arm, shoulder and hand scores). Over a five-year period (2016−2020), 20 selected cases (n = 20) requiring both soft and hard tissue reconstruction were assessed. On average, the harvested microvascular free flaps consisted of 7.8 ± 2.1 cm hard tissue and 86 ± 49.8 cm2 soft tissue components. At the donor site (subscapular region), only a mild morbidity was observed (DASH score: 21.74 ± 7.3 points). When comparing the patients’ postoperative quality of life to the established values of the healthy German norm population, the observed SF-36 values were within the upper third (>66%) of these established norm values in almost all quality-of-life subcategories. The mild donor site morbidity and the observed quality of life indicate only a small postoperative impairment when using the TDAP-Scap-aa free flap for the reconstruction of extensive maxillofacial defects.

Reconstruction of oral cavity defects using myogenous‐only scapular tip free‐flaps

Background

Oral cavity reconstruction is very challenging anatomical subsite to reconstruct. Large defects often require free tissue reconstruction to provide the best chance of form and function. Additionally, free tissue reconstruction aids to prevent fistula formation. We aimed to determine outcomes of oral cavity defect reconstruction using scapular tip free flaps with a myogenous intraoral component.

Methods

All patients with a mandibular or maxillary bony defect that included a disruption of the intraoral mucosa component between 07/1/14 and 07/31/17. Patients were reconstructed with a scapular tip free flap, which included a muscular component that was used to recreate the oral mucosa. The primary study outcomes were flap success rates, development of orocutaneous or oronasal fistula, rate of resuming oral diet as well as the occurrence of medical and surgical complications in the first month following surgery. The tested hypothesis was formulated before data collection began.

Results

Twenty‐five patients were identified by the study criteria. There was one (4%) flap that failed, while orocutaneous fistula occurred in two patients (8%). Prior history of osteoradionecrosis was a statistically significant predictor of overall complication (p < .05).

Conclusions

Intraoral myogenous reconstruction allows for re‐mucosalization of the oral cavity defect and is associated with high viability and low‐complication rates. In patients with amenable oral mucosal defects, a myogenous scapular tip free flap is a suitable reconstructive option.

Cephalometric and Functional Mandibular Reconstructive Outcomes Using a Horizontal Scapular Tip Free Flap

Scapula tip free flaps (STFFs) have become an increasingly popular option for head and neck reconstruction. The aim of this study is to demonstrate the feasibility of using the STFF in a horizontal orientation to take advantage of the anatomy of the scapular tip bone to re-create a mandibular symphysis. Eight patients underwent oromandibular reconstruction with a horizontally oriented STFF between October 2016 and June 2020. Virtual surgical planning was used to design the bony reconstruction in 6 cases. Primary outcomes, including flap survival, complications, and return to oral diet, were collected. Cephalometric measurements were obtained to compare preoperative and postoperative mandibular projection and width. All flaps survived without compromise, and no fistulas developed postoperatively. Seven patients returned to taking an oral diet. Cephalometric analysis revealed comparable measurements between preoperative and postoperative mandibles and reconstructed mandibles, respectively. STFFs may be oriented horizontally to reconstruct large anterior mandibular defects with satisfactory results.

Four Lessons Learned from Complications in Head and Neck Microvascular Reconstructions and Prevention Strategies

Free flap reconstruction in the head and neck region is a complex field in which patient comorbidities, radiation therapy, tumor recurrence, and variability of clinical scenarios make some cases particularly challenging and prone to devastating complications. Despite low free flap failure rates, the impact of flap failure has enormous consequences for the patients.

METHODS

Acknowledging and predicting high risk intra- and postoperative situations and having planned strategies on how to deal with them can decrease their rate and improve the patient's reconstructive journey.

RESULTS

Herein, the authors present 4 examples of significant complications in complex microvascular head and neck cancer reconstruction, encountered for the last 10 years: compression and kinking of the vascular pedicle, lack of planning of external skin coverage in osteoradionecrosis, management of the vessel-depleted neck, and vascular donor site morbidity after fibula harvest.

CONCLUSION

The authors reflect on the causes and propose preventative strategies in each peri-operative stage.

Scapular free flap as a good choice for mandibular reconstruction: 119 out of 280 cases after resection of oral squamous cell carcinoma in a single institution

Microsurgical procedures for reconstruction after resection of head and neck tumours have become standardised and reliable. Among them, the scapular free flap is used less often, mostly to avoid excessive operating times. We hypothesise that complex reconstructions after resection of oral squamous cell carcinoma (OSCC) are successful even with time-consuming free flaps such as the scapular free flap. In this retrospective, single-centre study, we used the evaluation of medical records to investigate the postoperative outcome of microvascular reconstruction after ablative surgery of OSCC. Associations among the categorical variables were analysed using Pearson's chi squared test or Fisher's exact test. Among the continuous variables, the t test or Mann-Whitney U test were used as appropriate. For multivariate analysis, the logistic regression model was calculated. In the sample of 280 free flap reconstructions, we performed 142 radial forearm and 119 scapular free flaps. The American Society of Anesthesiology (ASA) score (p=0.006) and the duration of the operation (p=0.010) are independent factors which influence the need for operative revisions. The type of free flap is irrelevant for that. With 4.2% flap losses, scapular free flaps were successful; even in patients ≥ 70 years old (0 flap losses). Complex reconstructions after surgical resection of OSCC are successful even in aged patients. The scapular free flap is a good choice for mandibular reconstruction despite the time-consuming intraoperative repositioning of the patient. In an increasingly ageing group of patients, who have more vascular diseases, scapular free flaps could be a very successful alternative after ablative surgery of oral squamous cell carcinoma.

Reconstruction of Complex Oromandibular Defects in Head and Neck Cancer: Role of the Chimeric Subscapular Free Flap

The purpose of this study is to present the chimeric scapula tip-free flap as a reconstructive choice in composite head and neck defects and to highlight the experiences of the authors in this field.A retrospective study and a literature review were conducted. Data about preoperative condition, intraoperative images, and radiological and clinical documentation were collected.Excision of head and neck advanced cancers may result in large composite defects containing different types of soft tissue and bone. This topic is particularly challenging in salvage surgery after radiation therapy. In this setting, reconstructive techniques are very complex and traditionally require the use of multiple microvascular flaps. Chimeric free flaps, based on the subscapular system, allow complex reconstructions, providing both soft tissue and bone on a single vascular peduncle.The regional anatomy of the subscapular system and the possible chimeric flaps that can be harvested will be discussed, together with the reconstructive surgical technique used and the positioning of the patient. Two representative clinical cases of complex head and neck reconstruction after radiotherapy are presented.Different types of chimeric flap can be harvested from the subscapular system. These flaps can include different tissues: skin, bone, muscle on a single vascular peduncle. This characteristic is particularly useful in complex defects with different tissue types involved, following large en-bloc excision of advanced head and neck tumors.Free flaps based on the subscapular system can be an excellent reconstructive choice in complex head and neck defects.

Novel Geometry of an Extended Length Chimeric Scapular Free Flap for Hemimandibular Reconstruction: Nuances of the Technique Streamlined by In-House Virtual Surgical Planning and 3D Printing for a Severely Vessel-Depleted Neck

Subscapular-based flaps have historically maintained an unparalleled ability to provide a multitude of bone and soft tissue components based on a single vascular pedicle. However, these flaps are often not thought of as an ideal choice for composite defects requiring extended lengths of bone for reconstruction. The ability to harvest long segments of bone and reliably perform multiple contouring osteotomies is fundamental to long-span composite mandibular reconstruction, and microvascular surgeons are often met with significant reconstructive challenges when fibular free flaps cannot be used owing to variant vascular anatomy or occlusive atherosclerotic disease in these specific clinical scenarios. This challenge is further compounded by treatment-related vessel depletion in the neck, which reduces the availability of suitable recipient vessels in close proximity to the reconstruction. We present a case in which all of the aforementioned challenges presented in a single individual, who concomitantly required hemimandibular reconstruction with treatment related vessel depletion in the neck and unsuitable bilateral vascular anatomy in the legs precluding the use of a fibular free flap. This case demonstrates a previously unreported flap component geometry for hemimandibular reconstruction using an extended-length chimeric scapular free flap with scapular tip, lateral scapular border, and parascapular fasciocutaneous skin paddle components.

Reconstruction of maxillectomy and midfacial defects using latissimus dorsi-scapular free flaps in a comprehensive cancer center

BACKGROUND

The standard of care for sinonasal malignancies is a large surgical resection followed by radiotherapy. Midfacial defects resulting from maxillectomy require a complex reconstruction procedure. Given their adaptability, chimeric flaps such as latissimus dorsi-scapular (LDS) free flaps appear to be a good option.

MATERIAL & METHODS

We performed a single-center retrospective study of consecutive patients with sinonasal cancers where a LDS free flap was used for reconstruction. We assessed the postoperative complications and the functional, aesthetic and oncologic outcomes.

RESULTS

Eighty-four patients were included. Primary tumors were staged as T4a in 68% of cases; 38.3% of the patients received induction chemotherapy and 82.7% received adjuvant radiotherapy. Based on our classification of midfacial and palatal defects, the majority of the patients (69%) had a type IIa with interruption of the three facial pillars. The orbital floor was removed in 55.9% of cases. The median follow-up was 45 months. Total flap necrosis with no possible revascularization occurred in 5.9% of cases. For the orbital reconstruction, a revision procedure was needed for necrosis and/or infection of the costal cartilage graft in eight cases (17%). More than 90% of the patients had no functional disorders regarding speaking, swallowing and chewing. Soft palate involvement was a prognostic factor of speech (p < 10^-4) and swallowing (p = .005) disorders. Dental rehabilitation was realized in 70.2% of the patients. No severe complications were observed in the donor site, except for one seroma.

CONCLUSION

A LDS free flap is a reliable technique for the reconstruction of complex midfacial defects.

VIDEO: Preoperative CT Angiography for Scapula Osteocutaneous Free Flap Reconstructions

OBJECTIVE. The objective of this video article is to discuss the use of the scapular osteocutaneous free flap in reconstructive procedures. We attempt to discuss normal and variant vascular anatomy, image acquisition via CT angiography, and image interpretation as well as computer-assisted design and manufacturing. CONCLUSION. The scapular osteocutaneous free flap is commonly used for maxillary and mandibular reconstructive surgery. The complex vasculature supplying the scapular region allows flap versatility. There are anatomic variations in the origin of the circumflex scapular and angular arteries. Our method of performing and reporting CT angiography for patients scheduled to undergo scapular osteocutaneous free flap procedures provides a reliable and reproducible means of communicating important elements of vasculature to surgeons. This in turn can facilitate the manufacturing of custom scapular cutting guides and improve surgical outcomes.

Osteocutaneous flaps for head and neck reconstruction: A focused evaluation of donor site morbidity and patient reported outcome measures in different reconstruction options

With significant improvements in success rates for free flap reconstruction of the head and neck, attention has turned to donor site morbidity associated with osteocutaneous free flaps. In this review, we address the morbidity associated with harvest of the four most commonly used osteocutaneous flaps; the free fibula flap, the scapula flap, the iliac crest flap and the radial forearm flap. A comprehensive literature search was performed to identify articles relevant to donor site morbidity for these flaps. We assessed morbidity in terms of incidence of delayed healing, chronic pain, aesthetic outcomes, site specific complications and patient satisfaction/quality of life. Weighted means were calculated when sufficient studies were available for review. The radial forearm and free fibula flaps are associated with high rates of delayed healing of approximately 20% compared to the scapular (<10%) and iliac flaps (5%). The radial forearm flap has higher rates of chronic pain (16.7%) and dissatisfaction with scar appearance (33%). For the majority of these patients harvest of one of these four osteocutaneous does not limit daily function at long-term follow-up. The scapular osteocutaneous flap is associated with the lowest relative morbidity and should be strongly considered when the recipient defect allows. The radial forearm is associated with higher morbidity in terms of scarring, fractures, chronic pain and wrist function and should not be considered as first choice when other flap options are available.

Scapula pre-augmentation in sheep with polycaprolactone tricalcium phosphate scaffolds

A scapula free flap is a commonly used method to reconstruct intraoral defects of the mandible and maxilla. Despite its clear advantages, it shows some deficiencies concerning the amount and shape of the available bone, especially with respect to later implant placement. To overcome these limitations, we pre-augmented the scapula prior to a potential flap-raising procedure with polycaprolactone (PCL) tricalcium phosphate (TCP) scaffolds in a sheep model. In our study, the scapula angle was augmented with a block of PCL-TCP in three adult sheep. After 6 months, the amount of newly formed bone and scaffold degradation were evaluated using cone-beam computed tomography scans and histomorphometric analysis. All animals survived the study and showed no problems in the augmented regions. The scaffolds were attached firmly to the scapula and showed a bonelike consistency. A fair amount of the scaffold material was degraded and replaced by vital bone. Our method seems to be a valid approach to pre-augment the scapula in sheep. In further experiments, it will be interesting to determine whether it is possible to transplant a modified scapula flap to an intraoral defect site.

A Tip for the Reconstruction of Larger Maxillary Defects in Complicated Cleft Patients

Residual alveolar cleft deficits can be difficult to treat. This is particularly the case in older and multiply operated patients as well as those with large oronasal defects and extensive scar tissue. In large and recalcitrant defects vascularized free tissue transfer should be considered as a definitive procedure. Vascularized free tissue transfer provides a 95% success rate and provides excellent bone for placement of osseointegrated implants for dental rehabilitation (Schwabegger et al., 2004). We feel that the scapula tip has a number of important advantages. These include reduced morbidity from the donor site, good bone quality and contour for implant placement, and a longer pedicle length.

Scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of a maxillectomy defect: A minimally invasive transaxillary approach

The purpose of this study was to propose a novel, minimally invasive transaxillary approach for harvesting the scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of a maxillectomy defect. A retrospective case series study of 4 patients who underwent reconstruction using a scapular tip composite free flap through the transaxillary approach was conducted. The data (age, sex, pathology, previous treatment and adjuvant treatment) were collected and analysed. Total operation time, number of hospital days and the cosmetic and functional outcome of reconstruction were analysed. Two male and two female patients were enrolled in this study. The patients' ages ranged from 52 to 59 years. All the patients had maxillectomy defects, with at least a classification of Okay type II, which were successfully reconstructed using a scapular tip and latissimus dorsi free flap through a minimally invasive transaxillary approach. The entire operation time for the primary tumour surgery and reconstruction ranged from 6.2 to 12.1 h (mean, 11.1 h). The average length of the hospital stay was 13 days (range, 10-16 days). No major donor site morbidity was observed, and there was no graft failure that required revision or exploration surgery. The minimally invasive transaxillary approach for harvesting the scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of maxillectomy defect is a promising approach for more favourable functional and aesthetic outcomes when compared to the use of other bone containing free flaps and the classic approach for harvesting scapular tip and latissimus dorsi free flap.
