Hypervascular floor of mouth tumor: Rare presentation of oral cavity squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common malignancy affecting the oral cavity and commonly presents as an exophytic lesion with red or white granular ulcerations. Most diagnoses are confirmed by biopsy and clinical features; however, early SCC has been shown to hide within benign appearing lesions, such as vascular tumors, resulting in missed diagnoses and delay in treatment. The following case report will discuss a patient who presented with a mass in the floor of the mouth which appeared as a vascular tumor on exam and imaging. This was originally thought to be benign based on FNA findings however was found to harbor invasive squamous cell carcinoma on final pathology. The goal of this case report is to provide a background on the variable presentations of OSCC, vascular tumors, and uncommon presentations for which specialists should be aware of in their practice.

Examining Trends in Implantable Arterial Doppler Usage Among North American Head and Neck Microsurgeons: A Survey Study.

BACKGROUND: There are variations in implantable arterial Doppler usage for microvascular free tissue monitoring among North American surgeons. Identifying utilization trends among the microvascular community may elucidate practice patterns that may be useful in determining protocols. Furthermore, study of this information may yield novel and unique applications in other disciplines such as vascular surgery. METHODS: Electronically disseminated survey study shared with a large database of North American head and neck microsurgeons. RESULTS: Seventy four percent of respondents use the implantable arterial Doppler; 69% report use in all cases. Ninety five percent remove the Doppler by the seventh postoperative day. All respondents felt that the Doppler did not impede care progression. Any implication of flap compromise was followed with a clinical assessment in 100% of respondents. If viable, 89% would continue monitoring after clinical examination, while 11% would take the patient for exploration regardless of clinical examination. CONCLUSIONS: The efficacy of the implantable arterial Doppler has been established in the literature and is supported by the results of this study. Further investigation is required to establish a consensus on use guidelines. The implantable Doppler is more often used in conjunction with rather than substitution for clinical examination.

Forked Paramedian forehead flap combined with nasolabial flap for pre-radiation coverage of exposed maxilla in the Total Rhinectomy patient.

Total rhinectomy is ontologically necessary for large and locally invasive carcinomas of the nasal cavity owing to the complex three-dimensional structure of the nose. Reconstruction options include singular or combined options of local tissue rearrangement, free flap reconstruction, and prosthetic reconstruction which may be delayed in the setting of post-ablative radiation therapy. If significant bony exposure is present prior to radiation, there is a substantial risk of osteoradionecrosis and the ensuing sequalae. In these cases, coverage of the bony defect may be advantageous prior to radiation and final reconstructive treatment. We present a case of a total rhinectomy defect for squamous cell carcinoma in a patient who had significant bony exposure prior to radiation which was resurfaced with a combined forked paramedian flap and nasolabial flap. The patient went on to be treated with a full course of radiation and had planned for a post-treatment nasal prosthesis.

Impact of smoking on donor site following rectus flap harvest for head and neck reconstruction.

OBJECTIVES: The rectus abdominis myocutaneous free flap has been widely used as a reconstructive option in head and neck reconstruction with great success. Challenging the popular assumption, this study sought to examine the effects of smoking on donor site complications in this population. METHODS: Multi-institution retrospective study of 103 patients (50 active smokers, 28 former and 25 never smoked). RESULTS: Overall complication rate was 14.5 %. Hernia rate 4.8 %, evisceration 0 %, dehiscence 2.9 %, infection 6.7 %. Smoking history did not significantlly influence complication rates (chi square test, p = 0.33). Abdominal wall closure technique also did not influence the complication rate (chi square test, p = 0.58). CONCLUSIONS: The rectus abdomonis myocutaneous free flap has an acceptable complication rate that does not appear to be influenced by smoking history. While patients should be counseled regarding smoking cessation, smoking habits should not delay treatment nor obviate consideration of rectus flap utilization.

Reviewing the External Jugular to Internal Jugular Vein Bypass for Circumventing Venous Congestion: Technique Description And Case Correlates.

This study reviews the operative technique of external jugular vein to the internal jugular vein (IJV) bypass and discusses its advantages of decreasing postoperative complications in bilateral neck dissection patients. A retrospective chart review was performed on 2 patients at a single institution with prior bilateral neck dissection and jugular vein bypass. The tumor resection, reconstruction, bypass, and postoperative management were led by the listed senior author (S.P.K). An 80-year-old (case 1) and a 69-year-old (case 2) underwent bilateral neck dissection with the creation of a micro-venous anastomosis. This bypass allowed for improved venous drainage without adding significant time or difficulty to the procedure. Both patients recovered well in the initial postoperative period with maintained venous drainage. This study describes an additional technique that the trained microsurgeon can consider during the index procedure and reconstruction that can benefit the patient without adding significant time or technical challenges to the remaining portion of the procedure.

Long segment spinal reconstruction of C3-T1 utilizing single strut fibula free flap following debridement and corpectomy for chronic osteomyelitis.

Cervical vertebral osteomyelitis (CVO) is a complex destructive pathology that presents as a significant challenge to reconstructive surgeons. Advanced cases of CVO involving neurologic deficits, spinal column instability, or refractory infection require surgical intervention with bony debridement and decompression followed by spinal reconstruction, realignment, and stabilization. Reconstruction of the spine is typically performed through an anterior approach with or without posterior instrumentation. Restoration of the anterior spinal column can be performed with titanium or PEEK cages, allograft bone or vascularized autograft bone. Anterior spine reconstruction using vascularized osseous free flaps has been well documented in the medical literature; however, to our knowledge, we report the largest osteomyelitic anterior cervical spine defect that has been reconstructed using a single strut osseous free flap. This was a complex case of cervical osteomyelitis in a patient with prior C4-C7 anterior cervical corpectomy and fusion who presented with instrumentation failure and septicemia. Anterior column reconstruction required a vascularized fibular strut spanning six vertebral levels from C3-T1, as well as a trapezius myocutaneous pedicled flap for posterior soft tissue coverage.

Revisiting the Cervicodeltopectoral Flap for Reconstruction of Cutaneous Head and Neck Defects: Technique Description and Clinical Presentation Correlates.

STUDY DESIGN: Technique Description with clinical presentation Correlates. PURPOSE: Revisit and discuss the advantages of the cervicodeltopectoral flap (CDP) as an alternative to microvascular reconstruction for head and neck cutaneous defects. METHODS: Retrospective chart review was performed on 2 patients with prior large cutaneous facial defects after tumor resection followed by cervicodeltopectoral flap reconstruction. These cases were performed at a single institution. The tumor resections, flap reconstructions, and postoperative management were led by the listed senior author (SPK). RESULTS: A 78-year-old (Clinical presentation 1) and 62-year-old (Clinical presentation 2) were evaluated for large nonmelanoma skin cancers of the face. Due to significant comorbidities, neither patient was an ideal candidate for microsurgical reconstruction. In both cases, lesion resection and CDP flap reconstruction was performed. The reconstruction allowed for successful coverage without significant donor site morbidity for each patient. CONCLUSIONS: The authors propose the addition of the CDP flap to the armamentarium of the head and neck reconstructive surgeon as a safe and reliable alternative to microvascular reconstruction.

Common Carotid-to-Internal Jugular Arteriovenous Loop for Single-Stage Microsurgical Reconstruction in the Radiated Vessel-Depleted Neck.

ABSTRACT: Management of head and neck defects in a radiated field can be quite challenging owing to the dearth of vasculature and significant degree of post-radiation fibrosis. In this setting, arteriovenous (AV) loop vascular grafts can bypass nonviable local vessels to provide viable and reliable inflow and outflow vessels for free tissue transfer in an otherwise hostile environment. Prior reports of the Corlett loop utilizing a cephalic vein transposition has been described however a common carotid-to-internal jugular AV loop has not been recently reported. Three patients underwent carotid artery to internal jugular vein AV loop creation to facilitate free-flap reconstruction secondary to radiation-induced vessel depletion. The specific technique described utilizes the saphenous vein as a donor and spares the cephalic vein for the possibility of flap complication. All three cases resulted in successful reconstruction, maintaining healthy tissue, vascular flow, and flap viability at all follow-up intervals. In our experience, vascular augmentation via AV loop formation provides reliable vascular inflow and outflow in the vessel-depleted neck to facilitate microvascular reconstruction. Sparing the cephalic vein yields an additional salvage mechanism in the event of venous congestion.

Potential Complications With Cryopreserved Cadaveric Veins in Arteriovenous Loop Formation for Head and Neck Microvascular Reconstruction.

ABSTRACT: Vessel depletion in the head and neck from radiation or previous surgical intervention adds to the operative complexity by limiting reconstructive options. Arteriovenous (AV) loop vascular grafts provide a conduit to bypass these nonviable local vessels to provide adequate blood flow. In certain situations, autologous donor vascular options are deficient or not readily available for creation of the AV loop. Cadaveric vein grafts provide an alternative option in these circumstances, but the efficacy and safety has not yet been delineated. In this study we discuss our experience utilizing cryopreserved cadaveric vein grafts for AV loop creation in head and neck reconstruction. In our initial cohort we aim to elucidate potential challenges and complications associated with the use of cadaveric vein grafts.

Open Versus Closing Wedge Osteotomy and Application to Mandibular Reconstruction.

PURPOSE: To review the specific techniques of closing wedge osteotomy and open osteotomy, compare their clinical and radiographic outcomes, and apply these findings to mandibular reconstruction. METHODS: A thorough review of the otolaryngology, facial plastic and reconstructive surgery, oral and maxillofacial surgery, and orthopedic surgery literature was conducted in the Ovid MEDLINE, EMBASE, and Google Scholar databases using the terms 'osteotomy' and 'mandibular reconstruction.' RESULTS: Traditionally, open osteotomies were thought to result in greater rates of malunion. However, multiple meta-analyses within the orthopedic literature have refuted this. Closing wedge osteotomies, on the other hand, may increase the chance of damaging a perforator. Again, no studies have evaluated the relationship between type of osteotomy and flap survival or wound healing. The particular type of osteotomy performed often depends on the type of osseous flap being utilized. CONCLUSIONS: Open osteotomies are a viable and even preferred alternative, particularly in flaps without consistent perforators, such as scapular free flaps.

Introduction of the American Academy of Facial Plastic and Reconstructive Surgery FACE TO FACE Database.

The American Academy of Facial Plastic and Reconstructive Surgery FACE TO FACE database was created to gather and organize patient data primarily from international humanitarian surgical mission trips, as well as local humanitarian initiatives. Similar to cloud-based Electronic Medical Records, this web-based user-generated database allows for more accurate tracking of provider and patient information and outcomes, regardless of site, and is useful when coordinating follow-up care for patients. The database is particularly useful on international mission trips as there are often different surgeons who may provide care to patients on subsequent missions, and patients who may visit more than 1 mission site. Ultimately, by pooling data across multiples sites and over time, the database has the potential to be a useful resource for population-based studies and outcome data analysis. The objective of this paper is to delineate the process involved in creating the AAFPRS FACE TO FACE database, to assess its functional utility, to draw comparisons to electronic medical records systems that are now widely implemented, and to explain the specific benefits and disadvantages of the use of the database as it was implemented on recent international surgical mission trips.

Implantable arterial doppler efficacy in free flap reconstruction: A systematic review and meta-analysis.

The implantable arterial doppler (IAD) is frequently used to postoperatively monitor free flaps with high accuracy, but there are no guidelines for its use. Bedside exam is used adjunctively to determine necessary intervention. This systematic review seeks to discover why the doppler is used adjunctively despite its established record of accuracy. Criteria for inclusion and exclusion were established. In total, 280 articles were found on PubMed and Web of Science, then screened accordingly. Data from 22 articles were analyzed using a bivariate hierarchical random effects model. Twenty-two studies yielded 2996 total patients undergoing 3127 free flap procedures. The meta-analysis found a high sensitivity of 0.809 (95% CI = 0.709, 0.880) and specificity of 0.966 (95% CI = 0.947, 0.979). False-positive rate was found to be 0.034 (95% CI = 0.021, 0.053). Positive and negative predictive values were 0.711 (95% CI = 0.581, 0.817) and 0.979 (95% CI = 0.966, 0.988). Positive and negative likelihood ratios were 24.7 (95% CI = 14.5, 39.5) and 0.20 (95% CI = 0.12, 0.30). The established efficacy of the IAD is supported by this study. Clinical exams may remain as the final adjunct due to the risks of inaccurate IAD signals. Further studies are warranted to optimize its use for future practice guidelines.

Delayed skin grafting protocol following Integra™ application for non-radiated scalp reconstruction for decreased wound depth and improved contour.

The clinical use of Integra™ has expanded to include scalp reconstruction since its FDA approval in 1996. Integra™, or dermal regeneration template, can be utilized in patients who are elderly with multiple medical comorbidities. Well-established Integra™ techniques utilize skin grafting 1-2 weeks following evidence of template vascularity. Most studies show the time to graft placement as <30 days, with almost all <52 days. No single article proposes a time frame for applying STSG after neodermis regeneration. Therefore, we aimed to describe our protocol to define a time frame for delaying scalp reconstruction with STSG following dermal regeneration. Over the last several years, the senior author has utilized a delayed reconstruction with skin grafting method where-in Integra™ is applied to either debrided bone or exposed pericranium in selected patients, and allowed to mature for ~6 weeks before performing skin grafting. The results have been predictable, reproducible, and have yielded high levels of patient and provider satisfaction due to the improved contour cosmesis. In this pictorial essay, the authors' novel protocol is detailed.

Analysis of vein grafting versus arteriovenous loop in microvascular head and neck reconstruction: Multicenter series of 36 patients.

BACKGROUND: The utilization of an arteriovenous loop is an underreported technique that affords the creation of reliable vascular options. Understanding the efficacy and impacting variables of microvascular reconstruction with an arteriovenous loop can be critical to its use. METHODS: Multi-institutional study of 36 patients who underwent vein grafting or AV loop with free tissue transfer. RESULTS: 58.3% of patients received prior radiation and 38.9% prior flap reconstruction. Flap success for vein grafting was 76% and AV loop was 100% (p = 0.16). Success for the radiated cohort was 90.5% and non-radiated 80% (p = 0.63). Flap success for the radiated, vein grafted patient was 83.3% and 100% flap success rate for radiated, AV loop patient (p = 0.49). Overall flap survival was 83.3% versus 97% overall success rate in the United States. CONCLUSION: The AV loop is a viable modality for vessel-depleted free tissue reconstruction. Radiation and previous surgery do not significantly impact flap success rates.
