Sternocleidomastoid flap for pedicled reconstruction in head & neck surgery- revisiting the anatomy and technique

Surgical closure of enlarged tracheoesophageal fistula after laryngectomy: A systematic review of techniques

OBJECTIVES

The objectives of the study were (1) systematically review the data on surgical closure of enlarged tracheoesophageal fistula after laryngectomy and (2) to perform a comparison of reconstruction of surgical techniques.

METHODS

Systematic review was performed using PRISMA methodology. Cumulative patient data were compared between patients reconstructed with vascularized tissue (sternocleidomastoid fascia and muscle, pectoralis major, deltopectoral, radial forearm) and those closed primarily (two-layer, three-layer, and tracheal transposition).

RESULTS

Fourteen studies reported outcomes for the reconstruction of tracheoesophageal fistula. Primary closure was used in 98 patients, vascularized flap in 74, and occlusive device in 8. Vascularized flap resulted in successful closure of the fistula in 89 % of cases compared to primary closure in 62 % (p = 0.0003).

CONCLUSION

Systematic review of the literature supports an improved surgical closure rate with vascularized flap interposed between the esophageal and tracheal lumens compared to primary closure.

Features of the use of ladder myoplasty of a gunshot wound to the laryngopharynx: Case report

INTRODUCTION AND IMPORTANCE

The laryngopharynx wound is considered to be one of the most severe wounds of neck both in war and in peace, as it may cause life threatening changes in the whole body (asphyxia, bleeding, shock). Important aspects of surgical treatment are to ensure full breathing, acceptable ways of feeding, and the use of reliable wound closure techniques aimed to prevent digestive tract failure and to maintain the framework and aerostasis of the laryngotracheal region.

CASE PRESENTATION

A case of unilateral multiple wounds of the laryngopharynx was described in the article. The features of diagnostics, surgical treatment and conservative therapy in the postoperative period with this injury were presented. The wounded man was urgently operated. During surgery the pharynx was mobilized. The metal fragment was removed. The wound of the pharynx was sutured with a two-row suture. The next stage of the surgical treatment was myoplasty. In the case of the patient, the purpose of myoplasty was additional sealing of the pharyngeal suture and myoplasty of the thyroid cartilage injury zone for the purpose of aerostasis. Because of the size of the wounds and their anatomical localization, we used the mobilized lower edge of the Musculus sternocleidomastoideus for myoplasty and proposed the method of ladder myoplasty developed by us.

CLINICAL DISCUSSION

In myoplasty method the following criteria must be followed: the muscle flap must be of sufficient length and width, so as not to cause excessive tension in the myoplasty area; the flap must be thick enough to avoid necrosis that may cause subsequent infectious complications; when taking the flap, the most sparing operative access should be used to avoid functional and anatomical disorders; the volume of the taken muscle flap must not lead to functional and anatomical disorders.

CONCLUSION

The proposed method of ladder myoplasty using Musculus sternocleidomastoideus is unique, and proves its high efficiency in unilateral multiple laryngopharyngeal injuries, and can be recommended for wide clinical implementation in such clinical situations.

Facial Reconstruction Using Sternocleidomastoid (SCM) Flap: A Review of the Literature

The sternocleidomastoid (SCM) flap has been used for a long time in protective coverage of major vessels, reconstruction of intraoral pharyngeal, closure of pharyngo-cutaneous fistulas, and augmentation of soft tissue defects in the oral and maxillofacial region. However, this flap is not yet commonly used due to doubtful blood supply to the flap. This flap offers favorable esthetic results, combined flap, rich vascularization, and the possibility of shifting the two heads of the muscle. Thus, this flap has been used broadly in the maxillofacial region to reconstruct the defects of the post-parotidectomy, mandible, pharynx, and floor of the mouth defects. Previous studies discussed the use of a SCM flap following parotidectomy. However, few studies explained the use of SCMs in facial reconstruction. This study aims to review published articles discussing the use of SCMs for facial reconstruction.

Digital surgery group versus traditional experience group in head and neck reconstruction: a retrospective controlled study to analyze clinical value and time-economic-social effect

Objective

Discuss the application value of digital surgical technology in the reconstruction of head and neck defects after tumor resection and comprehensively evaluate time-economic-benefit cost.

Methods

A retrospective analysis of head and neck cancer patients who underwent reconstructive operations in head and neck surgery at Sichuan Cancer Hospital from January 2015 to January 2021 was performed. According to the inclusion and exclusion criteria, a total of 52 cases were included, including 25 cases using digital surgery (DS) and 27 cases using the conventional surgery (CS). The clinical-pathological characteristics, postoperative complications, functional aesthetic evaluation indexes, and time-cost-satisfaction evaluation indexes between the two groups were compared and statistically analyzed. Typical cases using digital surgery were shared.

Results

Outcomes between the two groups were comparable, and there was no significant difference in survival outcome and follow-up time between the two groups (P > 0.05). There was no significant difference between the two groups in the defect size, pathological type, other major clinicopathological features, or operation-related indicators (P > 0.05). The incidence of titanium plate displacement, deformation or exposure, and facial scar deformity in the DS group was significantly lower than that in the CS group (P < 0.05). However, there was no significant difference in other short-term or long-term complications (P > 0.05). The incidence of dysphagia and eating disorders in the DS group was significantly reduced (P < 0.05). The speech and social functions were improved, but not significantly (P > 0.05). Meanwhile, there was no significant difference in the evaluation index of facial aesthetics in this study (P > 0.05). Furthermore, the total operation time, preparation time of bone flap from the donor site, osteotomy time, and reconstruction time in the DS group were significantly lower than those in the traditional operation group (P < 0.05), but the shaping time and vascular anastomosis time of recipient area could not be shortened (P > 0.05). In addition, there was no significant difference in total hospitalization days between the DS group and CS group (P > 0.05), but the time of ICU treatment and postoperative intravenous nutrition support in the DS group were shorter than those in the CS group (P < 0.05). In particular, the preoperative doctor-patient communication of the DS group was more effective, and the treatment satisfaction of patients including their families was higher after operation (P < 0.05).

Conclusion

Comprehensive application of digital surgical technology (CAD, CAM, VR, MA, etc.) in the reconstruction of the head and neck after tumor resection is feasible in clinical practice, which can not only improve the accuracy of repair, decrease some surgical complications, better preserve and improve patient’s diet and speech function, and reduce the operation and hospitalization time, but also increase the treatment cost. Furthermore, it is conducive to doctor-patient communication and improves patient satisfaction.
