The contralateral-based submental artery island flap: feasibility and oncological safety in oral cancer-related defect reconstruction.

ABSTRACT:

Objectives

Oncologic risk is a serious concern of submental artery island flaps. Here, we introduce the contralateral-based submental artery island flap (C-SAIF) and demonstrate its feasibility and long-term oncological safety in reconstructing oral cancer-related defects.

Methods

An anatomical study was performed concentrating on the pedicle length in seven cadavers. Then, a retrospective study was carried out on C-SAIF patients operated on by a single team. The standard surgical technique of C-SAIF was conducted. Outcomes including operative time, length of hospital stay, volume of intraoperative blood loss, and scores of the Multidisciplinary Salivary Gland Society (MSGS) questionnaire were compared with a similar cohort reconstructed with anterolateral thigh free flap (ALTF). In addition, oncological outcomes were evaluated by the 5-year cumulative survival rate between C-SAIF and ALTF patients.

Results

The pedicle length of C-SAIF was sufficient for the flap to be extended to the contralateral oral cavity. Fifty-two patients were included in the retrospective study, and nineteen of them underwent reconstruction with C-SAIF. The operative time of C-SAIF was shorter (p = 0.003), and the intraoperative blood loss was less (p = 0.004) than that of ALTF. There was no difference in MSGS scores. The results of survival analysis revealed comparable survival curves for the two groups in terms of overall survival, disease-specific survival, and disease-free survival.

Conclusion

C-SAIF is a feasible and reliable flap for reconstructing oral cancer-related defects. Moreover, it is an effective island flap to preserve the perforator and pedicle without compromising oncological safety.

Project description:ObjectivesTo explore the feasibility of making a submental perforator flap distal to the connecting line between the mastoid and the sternoclavicular joint under the guidance of neck-enhanced CT and repairing the postoperative defect of upper airway malignancy.Materials and methodsThis study retrospectively analysed 19 cases of upper airway malignant tumours treated in our department from January 2021 to September 2022, including 17 males and 2 females, aged 43-70 years.Site of lesions15 cases were in the laryngopharynx, 2 cases in the nasal cavity and paranasal sinus and 2 cases on the soft palate. All the lesions were malignant and at stages T2-4N0-2M0.Surgical methodThe extended submental perforator flap (size 22-15 × 6-7 cm) was prefabricated distal to the connecting line between the mastoid and the sternoclavicular joint. After tumour resection, the flap was used to repair the postoperative defect. Fifteen cases of laryngopharyngeal malignant tumours were repaired using the extended submental perforator flap with the vascular pedicle located on the opposite side of the tumour body. Two cases of nasal cavity and paranasal sinus tumours were repaired using the extended submental perforator flap combined with the temporalis muscle flap. The soft palate was completely removed in two patients with soft palate cancer and repaired using the folded extended submental perforator flap.ResultsBefore the surgery, the reflux vein was observed by neck-enhanced CT, including 12 cases returning to the internal jugular vein and 7 cases to the external jugular vein. All 19 cases in which flaps were used survived, and 1 case had a postoperative infection. All the patients had nasal feeding removed after surgery. The tracheal cannula was removed from the patients with laryngeal preservation, and the pronunciation was satisfactory. Among them, patients with soft palate cancer repair had mild nasal reflux symptoms with smooth breathing. During the follow-up period of 4-24 months, 18 patients had no tumour recurrence or metastasis, and 1 patient had cervical lymph node metastasis.ConclusionsThis study highlights the use of a submental perforator flap distal to the connecting line between the mastoid and the sternoclavicular joint to repair postoperative defects for upper airway malignancy as an innovative surgical approach that provides more tissue and good arteriovenous blood supply to adjacent sites. This method has high clinical value and provides an effective option for repairing postoperative defects of upper airway malignancy.
