Reconstructive considerations after resection of malignant melanoma in the head and neck

Little has been written about reconstructive methods after resection of melanomas in the head and neck region. We investigated reconstructive methods retrospectively related to the site and size of the melanomas resected by examining the medical records of 28 patients who had malignant melanomas of the head and neck resected at our hospital from 1984 to 2001. The tumour distribution was 12 in the cheek, 6 in the conjunctiva, 2 in the upper lip, 2 in the lower lip, one each in the lower eyelid, eyebrow, scalp, nose, and auricle. Reconstructive methods were 18 skin grafts, seven local flaps, and three free flaps. Three patients who had skin grafts required secondary reconstruction using free flaps. No local recurrences were observed. Reconstructions with local flaps give better aesthetical and functional results than free flaps and skin grafts. Immediate reconstruction with a flap is safe and it does not affect observation of local recurrences.     

Computerized imaging for soft tissue and osseous reconstruction in the head and neck

Recent developments in computer-aided medical imaging coupled with the related emergence of computer-aided design and manufacturing technology have had a significant effect on our management of patients with congenital and acquired head and neck deformities. In our institution, plain film skull radiography, cephalometry, and pluridirectional tomography have been largely replaced by high-resolution CT scanning augmented by planar reformations and three-dimensional surface reconstructions. A sophisticated computer-assisted radiologic imaging unit has been established to assist the surgeon and researcher. This marriage of advanced radiographic techniques, industrial computer-aided design technology, and clinical surgery have allowed us to better define aberrant anatomy, design new operative solutions for familiar as well as unusual problems, and quantitate changes of surgery and growth over time.

The tooth as a foreign body in soft tissue after head and neck trauma

Thorough evaluation of dentition is important in the management of craniofacial trauma. Avulsed or fractured teeth in the pulmonary and gastrointestinal tracts can lead to serious complications that are well described. However, the penetration of avulsed teeth into soft tissues of the head and neck is unusual and may not be recognized. Two cases in which a tooth became a foreign body in these soft tissues are illustrative. One patient had bronchoscopy for possible aspiration of an avulsed maxillary canine; it was later found embedded in the premaxillary tissues. The other patient had a right mandibular molar propelled into the posterior triangle of the left side of the neck. Physicians must be aware of dental injury resulting from facial trauma and account for all teeth as part of their evaluation, keeping an open mind as to where a missing tooth might be located.     

Adult head and neck soft tissue sarcomas

BACKGROUND: The purpose was to determine the optimal treatment for adult patients with head and neck soft tissue sarcomas. METHODS: We conducted a review of the pertinent literature. RESULTS: Local control after surgery alone or combined with radiotherapy was obtained in approximately 60% to 70% of the patients. The probability of local control is influenced by histologic grade, tumor size, and surgical margins. Patients with high-grade tumors and/or positive margins have improved local control if adjuvant radiotherapy is used. Distant metastases occurred in 10% to 30% of patients. The 5-year overall and cause-specific survival rates varied from approximately 60% to 70% and are affected by age, histologic grade, previous treatment of tumor, invasion of deep structures, and adequacy of surgery. CONCLUSIONS: The optimal treatment for adult head and neck soft tissue sarcomas is surgery. Adjuvant radiotherapy improves outcomes for those with high-grade tumors and/or positive margins. Radiotherapy alone will cure a small subset of patients with unresectable tumors.     

The role of parotidectomy in the treatment of cutaneous head and neck melanoma

Sixty-five patients with melanoma underwent parotidectomy as part of the initial treatment. Clinical evaluation of the parotid nodal status was inaccurate. Patients with parotid nodal metastases had a significantly decreased survival at 5 years, 22 percent compared with 67 percent in the patients with uninvolved nodes. Distant metastasis was the first indication of treatment failure in most of the patients with parotid involvement.     

Free tissue transfer in reconstruction following soft tissue sarcoma resection

Background: Radical surgical resection remains the single‐most important treatment in the curative multimodal therapy of soft tissue sarcomas. Refinements in surgical techniques have resulted in the development of function preserving approaches increasingly avoiding limb amputation. Patients and methods: The records of all patients (n = 34) who underwent microsurgical soft tissue coverage subsequent to primary resection of soft tissue sarcoma of the upper or lower limb from 1999 to 2009 are reviewed regarding postoperative complications, time until start of adjuvant radiation and functional outcome (Toronto Extremity Salvage Score, TESS). Results: Thirty‐four patients (range: 21–86 years) received a total of 35 free flaps. Complete tumor resection was obtained in 33 patients, one patient required re‐excision ultimately resulting in tumor‐free margin status (R0 resection). Major complications were encountered in four cases including one patient with complete flap loss requiring an additional free flap and three patients with partial flap loss requiring split‐thickness skin graft procedures. Minor complications were observed in three patients (9%). Extremity salvage could be achieved in 33 patients with adequate postoperative ambulation (TESS 84 ± 18) and adequate use of the upper extremity (TESS 80 ± 22). One patient underwent amputation. Mean time until start of adjuvant radiotherapy was 37 days (range 24–56 days). Conclusion: A synergetic center‐based interdisciplinary approach is crucial in therapeutical management of soft tissue sarcomas with the aim of R0 resection status and limb preservation. Plastic surgery contributes by offering microsurgical reconstruction using free tissue transfer, thus broadening surgical possibilities. This increases the chance of both adequate oncosurgical resection and limb preservation. © 2011 Wiley‐Liss, Inc. Microsurgery 2011.     

Osseous free tissue transfer in head and neck reconstruction

Large palatomaxillary and oromandibular defects have a dramatic impact on speech, deglutition, mastication, and cosmesis. Traditional methods of reconstruction, such as locoregional flaps, free bone grafts, alloplastic materials, and prosthetic devices, have difficulty providing meaningful aesthetic and functional reconstruction of these defects. This article discusses current concepts in the reconstruction of large composite palatomaxillary and oromandibular defects with an emphasis on the role of free tissue transfer, including the factors to be evaluated when choosing a method of reconstruction, indications for specific donor sites, and recent technical refinements.     

Post-burn head and neck reconstruction using tissue expanders

Tissue expanders have become useful adjuvants in reconstruction after burn. This study reviews experience with of tissue expanders in the treatment of head and neck burns, from April 2002 to February 2007; 82 expanders were used for 72 patients, all of whom underwent reconstruction at least 6 months after complete healing. The only major difference in this study from other techniques was the preoperative approach for selecting flaps and implants. The use is described of tissue expanders to enhance the area and provide suitable tissue for large expanded flaps for reconstruction of the face and neck. This was based on previous laboratory studies demonstrating that large flaps with very narrow pedicles remain well vascularised and can be transposed to cover very large defects. Satisfactory results were achieved after reconstruction in all cases. Tissue expansion, if carefully planned and conducted, is part of the treatment of choice for post-burn reconstruction of the head and neck, allowing an expanded flap suitable for versatile coverage.     

Second free tissue transfers in head and neck reconstruction

OBJECTIVE: As the era of free tissue transfer for head and neck reconstruction matures, more patients are requiring second resections and reconstructions. Our objective was to evaluate: patient characteristics, reconstructive options, flap survival, perioperative morbidity, and mortality. STUDY DESIGN: Retrospective chart review. SUBJECTS AND METHODS: Sixty-five patients underwent a second free tissue transfer separate from the time of the primary flap. RESULTS: The most common (53%) reason for a second flap was tumor recurrence. The most common flaps used were radial forearm and fibula in both the first and second reconstructions. Larger flaps were used in the second reconstruction. In-hospital mortality was 4.6 percent; medical complications occurred in 5 percent of patients. Flap survival was 97 percent; 13 percent of second flaps returned to the operating room for complications. Eight patients had a third free flap. CONCLUSION: A second free tissue transfer is a viable resource in head and neck reconstruction. Acceptable rates of flap survival and complications are encountered.     

The role of modified neck dissection in the treatment of cutaneous melanoma of the head and neck

One hundred eighty-one patients were treated with a modified neck dissection for suspected or proved metastatic melanoma during a ten-year period. The overall failure rate in the neck was 16%. Eighty-three percent of the patients with neck recurrence died of disseminated disease. A modified neck dissection that preserves important functional and cosmetic structures but does not compromise cancer control seemed to be appropriate treatment for actual or suspected melanoma metastatic to cervical nodes.
