Paramedian forehead flap reconstruction for skin tumors involving central subunit of face: An analysis of 37 cases

The Utility of the Paramedian Forehead Flap in Lower Eyelid Reconstruction

BACKGROUND

Malignant cutaneous eyelid tumors account for approximately 10% of all cutaneous cancers. Like other cancerous skin lesions, treatment commonly involves excision with wide margins, requiring tissue reconstruction. The use of the paramedian forehead flap (PMFF) has been described for reconstruction of the medial and upper eyelid, but literature is lacking for its use in lower eyelid anterior lamella reconstruction. We present a case series of patients who underwent reconstruction of lower eyelid defects using the PMFF.

CASE PRESENTATIONS

We present 2 patients who underwent reconstruction of lower eyelid defects using the PMFF surgical technique. The patients had previous history of lower lid repair with other reconstructive methods because of cancerous eyelid lesions. In addition, both received adjuvant radiation therapy, which led to development of ectropion. Postoperative signs, symptoms, and photographs were collected to monitor outcomes.

MANAGEMENT AND OUTCOMES

Reconstructions were performed by the collaborative efforts of a facial plastic reconstructive surgeon and oculoplastic surgeon using a staged PMFF approach. Postoperatively, both patients had significant improvement in ophthalmologic symptoms, particularly ectropion and lagophthalmos. At their most recent follow-up visit, they were satisfied with their functional and aesthetic outcomes.

CONCLUSION

The PMFF may be safely used to reconstruct defects of the lower eyelid anterior lamella. In this study, the PMFF has proven to be an excellent option for patients with complications after previous lower eyelid reconstructions or history of radiation therapy. Overall, the PMFF should be considered as part of the surgeon's reconstructive ladder when addressing lower eyelid defects.

The use of the paramedian forehead flap alone or in combination with other techniques in the reconstruction of periocular defects and orbital exenterations

PURPOSE

The paramedian forehead flap (PMFF) is a reconstructive option for large eyelid defects and orbital exenterations. We report a series of cases where PMFF reconstruction was carried out at various institutions in Australia.

METHODS

This study was a multi-centre, retrospective, non-comparative case series investigating the clinical outcomes of the PMFF for reconstructing periocular defects and orbital exenterations.

RESULTS

This case series describes twenty-seven patients (Female = 15, Male = 12), operated between 1991 to 2019, with a median age of 81 years (range: 45-93 years). Defect locations involved combinations of the medial canthus (16/27, 59.3%), upper eyelids (7/27, 25.9%), lower eyelid (4/27, 14.8%), both upper and lower eyelids (5/27, 18.5%), and orbital (7/27, 25.9%). There were no cases of flap necrosis. Minor post-operative complications were observed in ten patients with the most common being lagophthalmos. Median duration of follow-up was 17months (Range: 2months- 23years).

CONCLUSIONS

The PMFF is a versatile reconstructive tool for a range of periocular defects and orbital exenterations with minor post-operative complications.
