The radial forearm fasciocutaneous free-tissue transfer for tracheostomy reconstruction

Management of Parastomal Recurrence Following Total Laryngectomy

Parastomal recurrence occurs in around 5% of patients undergoing total laryngectomy for laryngeal squamous cell carcinoma. It carries a poor prognosis which has changed little over the last 50 years, and poses a significant challenge to the head and neck surgeon. At present, surgical excision offers the only realistic chance of cure, although patients must be selected carefully following thorough work-up and in-depth multidisciplinary team discussion. This article provides a review of the literature on the management of parastomal recurrence following total laryngectomy.

Free Flap Transplantation on the repair of defects caused by oral and maxillofacial tumors resection

Objective

To investigate the efficacy of free flap transplantation on the repair of tissue defects after oral and maxillofacial malignant tumor resection and its effects on serum sialic acid (SA) and interleukin-2 (IL-2).

Methods

Fifty-eight patients with oral and maxillofacial tumors were enrolled and set as the observation group. After the tumor resection, free flap transplantation was performed for postoperative repair. The postoperative efficacy, adverse reactions and follow-up indicators were observed. Moreover, 55 patients with benign tumors were enrolled into the control group, and 55 healthy persons were set as the healthy group. The levels of SA and IL-2 of the three groups were detected.

Results

In the observation group, 55 patients were successfully repaired (94.83%); 15 patients had adverse reactions after surgery. The follow-up duration was two to four years, and 45 patients survived for three years, with a survival rate of 77.59%. Before treatment, the serum SA level of patients with oral malignant tumor was significantly higher than those of the control group and healthy group, while the IL-2 level was significantly lower than those of the other two groups, and the differences were statistically significant (P<0.05). The serum IL-2 level in the observation group one day and fourteen days after surgery was higher than that before surgery, while the serum SA level was lower than that before surgery; the differences were statistically significant (P<0.05).

Conclusion

The application of free flap transplantation in the repair of postoperative tissue defects of oral and maxillofacial tumor resection is effective and has less complications, and the determination of both serum SA and IL-2 levels offers important references to recovery of patients with oral and maxillofacial tumors and prognosis evaluation.

Trichloroacetic Acid Chemocauterization: A Simple Method to Close Small Tracheocutaneous Fistula

OBJECTIVES

To evaluate the effectiveness of chemocauterization using trichloroacetic acid with or without suturing for the small tracheocutaneous fistula closure

METHODS

The Seoul National University Hospital database was analyzed retrospectively for 55 patients with a small tracheocutaneous fistula measuring less than 5 × 5 mm(2). Of these, 39 patients were treated by chemocauterization only, and 16 patients were treated by chemocauterization with suturing. Demographic, perioperative data, and treatment outcomes were evaluated for all patients.

RESULTS

The success rate of single trial was 56.4% (31/55), and the final success rate after repeated procedures if indicated was 80.0% (44/55). There were no statistically significant differences in age, sex, cannulation period, fistula size, presence or absence of maturation suture during tracheostomy, number of procedures, and success rates. Interval between decannulation and procedure was significantly different among 2 groups.

CONCLUSIONS

Trichloroacetic acid chemocauterization could be a simple, noninvasive, and safe method to close small tracheocutaneous fistula.

Tracheostoma reconstruction with the supraclavicular artery island flap

Tracheostoma wounds are complex defects that commonly occur in patients with vessel-depleted necks after cervical lymphadenectomy, who have multiple medical comorbidities, and a history of radiation therapy. The authors report reconstruction of 5 tracheostoma wounds using a pedicled, supraclavicular artery island flap as a reconstructive alternative. There were no flap losses, fistulas or leaks, revisions, or other complications. The supraclavicular artery island flap is a versatile, reliable, and effective option for tracheostoma reconstruction.

Microsurgical reconstruction of combined tracheal and total esophageal defects

OBJECTIVE

Lesions involving both the trachea and the esophagus are often considered inoperable because of the lack of reliable reconstruction. The purpose of this study was to review our experience of combined supercharged jejunal and other flaps for tracheal and esophageal reconstruction.

METHODS

A retrospective review of 5 consecutive cases with combined tracheal and total esophageal defects was performed. The esophageal defect was reconstructed with a supercharged jejunal flap, and the trachea was reconstructed with a free anterolateral thigh flap or a pedicled muscle flap.

RESULTS

Primary diagnosis included tracheostoma recurrence after a total laryngectomy for laryngeal cancer in 2 patients and tracheoesophageal fistula due to esophageal stenting for complications from prior treatment for non-Hodgkin's lymphoma, parathyroid cancer, and esophageal cancer in 3 patients, respectively. Tracheal and esophageal reconstructions were staged in 4 patients, and 1 patient received simultaneous reconstruction. Tracheal necrosis developed in 1 patient with a mediastinal tracheostoma, and the patient eventually died of infection 2 months later. The other 4 patients recovered well and resumed an oral diet.

CONCLUSIONS

Complex and often life-threatening lesions involving both the trachea and the esophagus are not necessarily inoperable. With careful planning, these combined defects can be safely reconstructed with multiple flaps with good functional outcomes and reasonable survival.

Anterolateral thigh free flap for tracheal reconstruction after parastomal recurrence

BACKGROUND

Stomal recurrence after total laryngectomy is 1 of the most serious issues in head and neck surgery, both because of the complexity of its management and because of its morbidity. Prior to the introduction of free-tissue transfer, mediastinal tracheostomy has been the standard reconstructive procedure with high rate of complications. The ideal reconstructive solution to these problems must provide well-vascularized soft tissues that can cover the defect after resection and also allow suturing of the tracheal remnant to skin edges without tension.

METHODS AND RESULTS

We describe a case of a 56-year-old man with stomal recurrence after total laryngectomy treated by the use of a tubed anterolateral thigh (ALT) flap to elongate the shortened trachea and simultaneously cover the cervical skin defect.

CONCLUSIONS

The ALT can be accepted as an ideal free-flap choice for stomal recurrence, because it has maximal reconstructive capacity and produces minimal donor-site morbidity.

Turnover Flap Closure of Recalcitrant Tracheostomy Fistula: A Simplified Approach

BACKGROUND

Chronic and nonclosing tracheostomy fistula can often significantly impair quality of life, vocalization, and local hygiene. Although many of these fistulas close on their own after decannulation or after local debridement, a significant percentage do not and require flap closure. In this article, the authors present their experience with a multilayered flap closure technique that has proven reliable, quick, and extremely easy to perform, even in recalcitrant cases.

METHODS

A medially based turnover skin flap closes the tracheal defect without tension and does not narrow the lumen. Double and layered local muscular coverage provides healthy soft-tissue coverage and eliminates a tethered and depressed scar appearance. Skin closure respects relaxed tension lines.

RESULTS

Six patients with recalcitrant tracheostomy fistula have to date undergone this repair without recurrence, and cosmesis has been excellent.

CONCLUSIONS

Complicated and recurrent tracheal fistulas are successfully treated with a tension-free, multilayered flap reconstruction; the design incorporates fundamental aesthetic and reconstructive principles.

Tracheostomal and Cervical Esophageal Reconstruction with Combined Deltopectoral Flap and Microvascular Free Jejunal Transfer after Central Neck Exenteration

BACKGROUND

Combined defects of the skin, larynx, pharynx, and esophagus after central compartment exenteration of the neck can be extremely difficult to reconstruct. The objective of this article is to evaluate reconstruction of the central compartment using a combination of free jejunal transfer for pharyngoesophageal reconstruction, together with regional deltopectoral flaps for tracheostomal reconstruction and cutaneous resurfacing. Myocutaneous flaps, such as pectoralis major and latissimus dorsi flaps, have been used previously for external coverage but can be bulky, causing obstruction of the tracheostoma.

METHODS

From 1995 to 2002, seven patients underwent reconstruction of the central compartment with seven jejunal and nine deltopectoral flaps. Five patients required resection for tracheostomal recurrence of squamous cell carcinoma, and two patients required resection for massive pharyngocutaneous fistulas. Flap survival, complications, and outcomes were evaluated retrospectively.

RESULTS

The mean age of the patients was 68.7 years and the mean length of follow-up was 1.9 years. Overall free jejunal and deltopectoral flap survival was 100 percent, with no partial loss. All patients maintained an adequate airway with stomal patency.

CONCLUSIONS

These complicated defects can be effectively repaired with free jejunal transfers to restore continuity of the alimentary tract and deltopectoral flaps to reconstruct the tracheostoma and surrounding cutaneous defects. The deltopectoral flap provides a large volume of well-vascularized tissue that provides reliable coverage of the newly reconstructed cervical esophagus and exposed major vessels following exenteration of the central compartment. Its thin, pliable nature allows suturing of the tracheal remnants to skin edges without tension and avoids intraluminal prolapse of excess soft tissues, thus maintaining stomal patency.
