Single perforator based anterolateral thigh flap for reconstruction of large composite defects of oral cavity

Composite defects of oral cavity are a reconstructive challenge. Anterolateral thigh flap provides large and pliable tissue for reconstruction of these defects. However, wide variations in the vascular anatomy, variable perforator number and location are reported. The aim of this study was to evaluate the reliability of single perforator based large anterolateral thigh for reconstruction of complex oral cavity defects following ablative surgery. We report a series of 25 consecutive patients who underwent reconstruction of oral cavity defects with anterolateral thigh flap based on single perforator between August 2009 and August 2010. The mean flap dimension was 261cm(2) (range 80-540cm(2)). In 21 patients the flap was bi-paddled and used for inner and outer lining for cheek. None of the flaps developed perforator insufficiency. Two flaps were lost due to delayed neck wound sepsis after 7th post operative day. This study establishes safety and reliability of using a large and/or bi-paddled anterolateral thigh flap based on single perforator for reconstruction of complex oral cavity defects.     

Assessment of the perforators of anterolateral thigh flaps using 64-section multidetector computed tomographic angiography in head and neck cancer reconstruction

Background

The anterolateral thigh (ALT) flap is a frequent choice for free flap transfer in head and neck cancer reconstruction because of its versatility. Preoperative mapping of the perforator pedicles of an ALT flap is still a challenge because of variations in vasculature. Although computed tomographic angiography (CTA) is used increasingly to evaluate the peripheral vasculature, the use of this method for evaluating the perforators of an ALT flap has not been described in detail.

Methods

From September 2008 to March 2009, 32 patients underwent preoperative CTA before free ALT flap transfer for head and neck cancer reconstruction. The perforators were marked on a 64-section multidetector CT image for each patient. The preoperatively mapped perforators were compared with the actual intraoperative findings. Flap success rates and associated morbidity and complications were recorded.

Results

Preoperative CTA identified major variations in perforators. Eighty-four were found by preoperative CTA; 64 of these were mapped to be explored during the operation, and 13 additional perforators were identified during surgery. The accuracy rate of identifying the branching origin of the ALT perforators was 98% (63/64). All of the ALT flaps survived except for one with necrosis (survival rate 97%). There was no donor site morbidity.

Conclusions

Preoperative mapping of perforators by CTA proved valuable in free ALT flap transfer and shortened the operation time significantly. This modality provides useful information for head and neck cancer reconstruction in difficult cases, especially in patients with large or through-and-through defects that might need multiple perforators in flap design.

Use of the double-paddle anterolateral thigh flap for locally advanced tongue carcinoma requiring second site reconstruction

BackgroundAdvanced oral tongue carcinoma can present with extension beyond the oral cavity. Operative defects after resection may involve multiple anatomical sites and significantly impact speech and swallowing. Dependence on long-term enteral feeding is not uncommon for these patients. The anterolateral thigh (ALT) flap is one of the most reliable and flexible flaps used in the reconstruction of total and subtotal tongue defects. The double-paddle flap modification may be a more suitable option for complex oral tongue defects after advanced tumor ablation.MethodsCase series of 31 patients with oral tongue squamous cell carcinoma that were classified as stage IV. The age of patients ranged from 32 to 63 years. We designed the double-paddle ALT flaps to reconstruct the two-site surgical defects (tongue defect and pharynx or neck skin defect). Postoperative viability of the flap was checked by clinical observation. The last examination was performed at 3-months after the completion of adjuvant chemoradiotherapy. The functional capacity of our patients was evaluated by three physicians (Head and Neck Surgeon, Radiation Oncologist, and Physiatrist) using a Speech Intelligibility Score and the Functional Oral Intake Scale.ResultsA total of 31 patients with surgical defects after total or subtotal tongue resection for cancer underwent double-paddle ALT flaps for reconstruction from March 2018 to December 2019. The dimension of flaps from 8 × 12 cm to 10 × 18 cm were divided into double-paddle from 8 × 5 cm to 10 × 10 cm. There was one case of pedicle thrombosis, one case of postoperative bleeding, three cases of neck infection, and six cases of salivary fistula. Our patients were seen in follow up from 6 to 36 months, with median follow-up of 23.5 months. The survival rate of ALT flap was 100%. All of our patients achieved an oral diet by 9 months after surgery. The mean score speech intelligibility was 2.74 ± 0.68 (4-point ordinal scale). The 2-year disease-free survival rate was 61.3%.ConclusionsThe double-paddle ALT flap is a reliable flap suitable for oral defects involving multiple subsites after ablative procedures. The majority of patients demonstrated acceptable functional rehabilitation.Clinical question/ level of evidenceTherapeutic, IV.     

Cheek-neck advancement-rotation flaps following Mohs excision of skin malignancies

The cheek-neck advancement-rotation flap has proved extremely useful for delayed reconstruction of the face following the microscopically controlled surgical excision (MCSE) of skin malignancies. We have recently used these flaps successfully to repair combined defects of the cheek and nose in eight patients, isolated cheek defects in six patients, combined defects of the cheek and lips in two patients, and isolated defects of the nose, temple, and an antral cutaneous fistula in each of three patients. Defects as large as 6.0 X 10.0 cm have been closed in one stage with this flap. This flap is extremely hearty and its scars can be well concealed. It is especially valuable in the elderly patient and should always be considered as one of the options for reconstruction of the face following MCSE of skin malignancies.     

A novel technique for cheek mucosa defect reconstruction using a pedicled buccal fat pad and buccinator myomucosal island flap

Reconstruction of cheek mucosa defects following tumor resections can be approached with several techniques, depending on size of the defect. Fasciocutaneous and perforators free flaps are widely employed today for such reconstructions. However, small defects or general health of the patient may limit their indications. Furthermore, approaching moderate size defects, some techniques, like temporalis muscle or fascia pedicled flaps, lead to contracture with limitation of mouth opening or trisma, and others, like intraoral local flaps, do not provide enough tissue for the reconstructions. In this work the authors propose, for reconstructing these kind of defects, the use of a buccinator myomucosal island flap and a buccal fat pad pedicled flap association. A case is reported and the surgical technique is explained. This new reconstructive technique can easily be used for reconstructing moderate-sized cheek defects, achieving optimal results: the internal mucosal lining is restored in few weeks without any retraction, contracture, of scars on the face limiting the aesthetic outcome and mouth opening.     

Oral squamous cell cancer: early detection and the role of alcohol and smoking

Defects in head and neck after tumor resection often provide significant functional and cosmetic deformity. The challenge for reconstruction is not only the aesthetic result, but the functional repair. Cancer may involve composite elements and the in sano resection may lead to an extensive tissue defect. No prospective randomized controlled studies for comparison of different free flaps are available. There are many options to cover defects and restore function in the head and neck area, however we conclude from experience that nearly all defects in head and neck can be closed by 5 different free flaps: radial forearm flap, free fibula flap, anterior lateral thigh flap, lateral arm flap and parascapular flap.     

Healing of lined and unlined parasitic and nonparasitic flaps

The importance of lining and maintaining a continuing in-continuity blood supply has been emphasized for optimum healing and decreasing the amount of contracture following full-thickness cheek resection. An experimental model has been designed to test this hypothesis. Twelve squirrel monkeys were used with carefully measured forehead flaps cut and placed into cheek defects of the same size. The flaps and defects were tattooed and cut as squares 1.5 cm on each side. In six, a full-thickness cheek defect was created leaving the forehead flap unlined when placed in the defect. In the remaining six a mucosal surface was retained leaving a lined flap following setting it into the cheek defect. At 3 weeks, three of the lined and three unlined flaps were divided creating parasitic flaps. Three lined and three unlined flaps were not divided, remaining as nonparasitic flaps. Healing characteristics were observed and measurements of total perimeter, external surface area, and tracings of the flaps were made at 3 weeks, 1 month, 2 months, and 3 months. Results in the models utilized do not verify any difference in the quality of healing or amount of contracture.
