Pharyngocutaneous and tracheoesophageal fistula closure using supraclavicular artery island flap

Experience of using a supraclavicular flap in reconstruction of oral cavity defects

Introduction. In case of cancer of the oral mucosa at the first stage, the standard treatment approach is radical surgical intervention, with the formation of extensive defects leading to aesthetic and functional disorders. Taking into account the characteristics of defects, choosing a flap is a difficult task. Currently, there is a wide selection of regional and microvascular free flaps. However, not all flaps meet the requirements. The supraclavicular fasciocutaneous flap, being a regional flap, has a number of advantages: easy to harvest, reliable due to the constancy of the vascular pedicle, primary closure of the donor site, scarcity of hair, the possibility of closing various defects of the oral cavity.

 Aim. To evaluate the possibility of using a supraclavicular flap in patients with oral cancer to restore the defects after surgical treatment.

Materials and methods. The study included 10 patients with malignant tumors of the oral cavity who underwent surgical intervention with defect replacement using supraclavicular flap at the N. N. Blokhin National Medical Research Center of Oncology between February of 2015 and May of 2021. In 4 cases, buccal mucosa was affected; in 3 cases, the retromolar area; in 1 case, oral floor mucosa; in 1 case, mandibular alveolar ridge; in 1 case, mobile tongue. Flap sizes were 5–10 × 5–8 cm. Three (3) patients had history of radiotherapy, and 1 of them had a radical dose.

Results. In 4 patients without previous radiotherapy, partial flap necrosis was observed. In 1 patient, sutural diastasis in the oral cavity after partial flap necrosis was diagnosed. There were no cases of total flap necrosis and fistula formation. Suture dehiscence in the donor bed was observed in 1 patient only.

Conclusion. Use of supraclavicular flap is an option for oral cavity defect replacement after surgical intervention in patients with malignant tumors of the oral cavity producing satisfactory esthetic and functional results. The advantages of this flap are simple flap dissection, reliability of vascular pedicle, flexibility, possibility of replacing large defects, scant hair coverage.

Radial forearm free flap and a freka-trelumina tube for management of a refractory pharyngocutaneous fistula: A case report

The management of pharyngocutaneous fistulas (PCFs) is challenging. A multidisciplinary treatment approach according to the clinical needs of a patient is essential for PCF management. Here, we describe the use of a double-layer closure technique involving a radial forearm free flap (RFFF) and a Freka-Trelumina nasojejunal tube in the reconstruction of a refractory PCF.

Tracheoesophageal fistula and pharyngoesophageal stenosis repair by double skin paddle radial forearm flap

Tracheoesophageal fistula (TEF) constitutes a rare, but serious complication in laryngectomized patients, usually occurring after radiotherapy. TEF may occur spontaneously or may be due to enlargement of the TEF created for placement of a voice prosthesis. Surgical treatment of TEF can be complex, especially in the presence of a concomitant pharyngoesophageal stenosis (PES), and is associated with a high failure rate. In this article, we describe the surgical reconstruction technique for TEF associated with PES using a double skin paddle fasciocutaneous radial forearm free flap. The key points of this technique consist of correct positioning of the 2 skin paddles in order to reconstruct the anterior pharyngoesophageal wall and posterior tracheal wall, as well as de-epidermization of the intermediate part of the flap, which is then placed in the tracheoesophageal space.

Application of the Supraclavicular Artery Island Flap for Fistulas in Patients With Laryngopharyngeal Cancer With Prior Radiotherapy

OBJECTIVE

To evaluate the effect of the supraclavicular artery island flap (SAIF) in reconstructing pharyngocutaneous fistula in patients with laryngopharyngeal cancer with prior radiotherapy.

METHODS

Six patients with laryngopharyngeal cancer with pharyngocutaneous fistula due to previous radiotherapy and surgery during 2016 to 2019 were retrospectively analyzed. Initially, the fistula was treated conservatively. The SAIF was applied with double folding technique to reconstruct fistula in the patients who failed to heal after conservative treatment.

RESULTS

The fistulae closed in 4 patients after conservative treatment. After SAIF operation, fistula closure was achieved in the other 2 patients who received highest dose of radiation and had largest fistulae size. The flaps grew well and there were no donor-site complications in these 2 patients. All patients achieved oral feeding without any complications.

CONCLUSION

The SAIF is an effective and safe approach to reconstruct the pharyngocutaneous fistula after laryngopharyngeal surgery in patients with laryngopharyngeal cancer with previous radiotherapy, especially for those who have received high-dose radiation and have large fistula.

Supraclavicular Artery Island Flap: Critical Appraisal and Comparison to Alternate Reconstruction

OBJECTIVES/HYPOTHESIS

The supraclavicular artery island (SAI) flap may be a good option for selected head and neck reconstruction due to its reliability, ease of harvest, and favorable color match. The objective of this study was to examine the rates of complications for the SAI flap in head and neck oncologic reconstruction, with examination of risk factors and comparisons to alternative flaps often considered the gold-standard soft-tissue flaps for head and neck reconstruction: the pectoralis myocutaneous (PMC), radial forearm free flap (RFFF), and anterolateral thigh (ALT) flaps.

STUDY DESIGN

Retrospective cohort study.

METHODS

Consecutive SAI flaps were compared to PMC, RFFF, and ALT flaps (non-SAI flap group), all performed by the senior author from 2010 to 2018. The non-SAI flaps were included if an SAI flap could have been performed as an alternate flap. The groups were compared based on demographics, flap dimensions, site of reconstruction, operating time, total hospital stay, total hospital costs, and complications.

RESULTS

One hundred seven SAI flaps and 194 non-SAI flaps were identified. SAI flaps were used less commonly than non-SAI flaps for mucosal defects (P < .001). The SAI flap dimensions were narrower but longer than non-SAI flaps (P < .001). SAI flaps had higher rates of total complications, partial flap necrosis, flap dehiscence at the recipient site, fistula, donor site dehiscence, and minor complications compared to non-SAI flaps (all P < .05). SAI flaps had higher rates of total complications, recipient site dehiscence, fistula, and minor complications in both the oral cavity and all mucosal sites compared to non-SAI flaps (all P < .05). SAI flaps for mucosal reconstruction were associated with higher rates of total complications (54% vs. 34%, P = .04), flap dehiscence at the recipient site (32% vs. 14%, P = .03), and major complications (21% vs. 5%, P = .02), compared to cutaneous reconstruction. Complications were equivalent between SAI flaps and non-SAI flaps for cutaneous reconstruction (all P > .05). Multivariate analysis showed that SAI flaps were associated with any postoperative complication (odds ratio [OR]: 3.47, 95% confidence interval [CI]: 1.85-6.54), partial flap necrosis (OR: 5.69, 95% CI: 1.83-17.7), flap dehiscence (OR: 5.36, 95% CI: 2.29-12.5), donor site complications (OR: 11.6, 95% CI: 3.27-41.0), and minor complications (OR: 5.17, 95% CI: 2.42-11.0). Within the SAI flap group, SAI flap length >24 cm was associated with postoperative complications on multivariate analysis (OR: 5.09, 95% CI: 1.02-25.5, P = .048).

CONCLUSIONS

The SAI flap is best suited for cutaneous reconstruction of the face, neck, and parotid/temporal bone regions due to the favorable color match; the thin, pliable nature of the skin; ease of harvest; and equivalent complication rates compared to alternate soft-tissue flaps. However, the SAI flap is associated with more complications for oral cavity and mucosal site reconstruction when compared to RFFF and ALT flaps and should be used in selected cases that do not require complex folding. For all sites, flaps longer than 24 cm should be used with caution.
