The supraclavicular artery flap for lateral skull and scalp defects: effective and efficient alternative to free tissue transfer

Application of supraclavicular island flap in oral and maxillofacial reconstruction

Several surgical modalities are available for maxillofacial reconstruction as locoregional or microvascular free flaps.

PURPOSE

(a) Evaluate the reliability of the supraclavicular flap in cervico-orofacial region; (b) investigate the role of computed tomography angiography (CTA) in predicting the post-operative viability of the flap; (c) assess the speech, feeding, and esthetics after reconstruction using this flap.

METHODS

Eleven patients included in this study underwent either conventional or delayed harvesting of the supraclavicular flap (SCF). All the patients had diagnostic computed tomography angiography (CTA) of the supraclavicular flap before the surgery.

RESULTS

The mean harvesting time of the flap was 45.45 ± 4.16 min. The average length of the flap was 22.64 ± 1.12 cm, whereas the mean width of the flap was 6.14 ± 1.14 cm. The flap survived in 9 patients, while two patients had complete flap loss. After the surgery, three patients complained of speech difficulties. Two patients had swallowing problems. After the surgery, three patients complained of speech difficulties. Two patients had swallowing problems. Only two patients complained of weakness in the donor site. None of the patients reported that the weakness or pain at the donor site affected their daily activities or quality of life.

CONCLUSION

The pedicled SCF represents a safe and feasible option that can be used to reconstruct a wide array of maxillofacial oncologic defects. However, a study with a larger sample size is recommended to achieve more reliable clinical results for the modified delayed technique modification in terms of their effect on the survival of the supraclavicular flap.

Usefulness of supraclavicular flap in reconstruction following resection of oral cancer

Objective

To evaluate the usefulness of supraclavicular artery flap in reconstruction of defects following resection of buccal mucosa cancer.

Methods

Twenty-five patients who presented to R.L Jalappa Hospital and Research centre and diagnosed as squamous cell carcinoma of buccal mucosa staged T₂ and above were included in our study. All patients underwent wide excision of tumour and neck dissection. Six patients underwent hemi-mandibulectomy while 4 patients underwent marginal mandibulectomy depending on extent of the tumour along with neck dissection. The defect following surgery was reconstructed using the supraclavicular artery flap and were followed up for minimum 6 months during which they were assessed for the functional and aesthetic outcome using a scoring system. The details of the scoring system comprised of 7 attributes. Each attribute was given a score of 10 if the patients experienced that attribute, while a score of 0 was given if the patient did not experience that particular attribute.

Results

Seven (28%) patients had complete necrosis of the flap. One patient had a local recurrence 2 months following surgery and was lost to follow up. The remaining 17 patients were followed up for a minimum of 6 months and a scoring system was adopted to evaluate the functional and aesthetic outcome of the supraclavicular flap. We observed that 14 patients had an excellent outcome score (58%), 3 patients had a good outcome score (13%), while 7 patients (28%) had flap necrosis.

Conclusions

We find the supraclavicular flap to be safe, technically simple, sensate, thin, pliable and reliable regional fasciocutaneous flap in reconstructing intra oral defects. Preserving the external jugular vein and sacrificing supraclavicular nerves give good outcome.

[Reconstruction with supraclavicular island flaps : An option in oncological treatment of head and neck carcinomas]

BACKGROUND

Reconstruction of defects after extirpation of head and neck cancer is a highly challenging and complex surgical undertaking. Commonly used techniques, e.g., the radial forearm flap, the anterior lateral thigh flap, or flaps harvested from the chest-deltopectoral or pectoralis major-share numerous disadvantages, such as donor-site morbidity, poor color matching for cutaneous reconstruction, and excessive tissue bulk. The use of a supraclavicular artery island flap is a long-forgotten but increasingly popular option for reconstruction in the head and neck area.

MATERIALS AND METHODS

In the period 03/2013-02/2016, a total of 12 patients were treated with a supraclavicular island flap after surgical resection of carcinoma of the oral cavity, pharynx, parotid, or facial skin.

RESULTS

Using examples, reconstruction of the lateral tongue and tongue base following resection of a squamous cell carcinoma, and reconstruction of the parotideal region after total parotidectomy and neck dissection for a skin spinalioma that had infiltrated the parotid are reported. In both patients, the flap healed without problems and led to very good functional and cosmetic outcomes.

CONCLUSION

The supraclavicular island flap is a reliable and versatile flap for reconstruction in the head and neck region. Minimal donor-site morbidity, excellent cosmetic properties, and the relative ease of preparation and use compared to other distant flaps render it an excellent reconstructive tool for ENT surgeons.

Orofacial Soft Tissue Reconstruction with Locoregional Flaps in a Health Resource-Depleted Environment: Experiences from Nigeria

Background

Reconstruction of orofacial soft tissue defects is often challenging due to functional and aesthetic demands. Despite advances in orofacial soft tissue defect reconstruction using free flaps, locoregional flaps still remain an important option, especially in health resource-depleted environments. This retrospective study highlights our experiences in oral and maxillofacial soft tissue reconstruction using locoregional flaps.

Methods

A twenty-three years retrospective analysis of all patients managed in our department was undertaken. Information was sourced from patients' case notes and operating theater records. Data was analyzed using SPSS ver. 16 (SPSS Inc.) and Microsoft Excel 2007 (Microsoft).

Results

A total of 77 patients underwent orofacial soft tissue defect reconstruction within the years reviewed. Males accounted for 55 (71.4%) cases and trauma was the main etiological factor in 45 (58.4%) of the patients treated. When sites of defect were considered, the lip, 27 (32.1%), was the most frequent site followed by the nose, 17 (20.2%). Forehead flap, 51 (59.3%), was the most commonly used flap. Complications noted were tumor recurrences at the recipient bed in 3 (3.9%) cases, tumor occurrence at the donor site in 1 (1.3%) case and postoperative infection in 11 (14.3%) cases.

Conclusions

Locoregional flaps still have an important role in the rehabilitation of patients with orofacial soft tissue defects. They remain a vital tool in the armamentarium of the reconstructive surgeon, especially in health resource-depleted environments where advanced reconstructive techniques may not be feasible.

Reconstruction of Lateral Skull Base Defects

Objectives

To compare reconstructive techniques, operative times, duration of hospitalization, and need for subsequent flap revisions between reconstructive approaches to lateral skull base defects.

Study Design

Case series with chart review.

Setting

Tertiary academic referral center.

Subjects

Patients (n = 31) undergoing reconstruction of composite lateral skull base defects from 2002 to 2014.

Methods

Data were analyzed for demographics, tumor characteristics, reconstructive technique, operative time, duration of hospitalization, complications, and outcomes.

Results

Thirty-one patients were identified for inclusion. Lateral temporal bone defects resulted from resection of malignant lesions, including squamous cell carcinoma (n = 25), basal cell carcinoma (n = 2), and other carcinoma (n = 4). Defects were reconstructed with submental flaps (n = 16), pedicled latissimus dorsi flaps (n = 6), and free anterolateral thigh flaps (n = 9). All cases involved neurosurgery, neurotology, and head and neck surgery services. Although time of surgical resection was similar, time saving was noticed with submental reconstruction. Compared with free flaps, submental flap reconstruction was associated with significantly reduced total operative time (mean, 544 vs 683 min; P = .00817) and duration of hospitalization (4.9 vs 9.8 days; P = .02067). Submental flaps were significantly less likely to require revision debulking procedures (mean = 0.6) compared with latissimus dorsi flaps (mean, 1.3; P < .00001) and free flaps (mean, 1.6; P < .00001). There was 100% flap survival.

Conclusion

The musculocutaneous submental flap provides an excellent option for reconstruction of lateral skull base defects given its proximity, reliability, ease of harvest, and exceptional color match. Submental flap reconstruction was associated with reduced operative time, hospitalization duration, and flap revisions.
