Background: Basal cell carcinoma (BCC) is the most common skin malignancy, with the pigmented solid subtype being a rare variant. Surgical excision with clear margins remains the mainstay of treatment, but reconstruction of facial defects requires careful planning to optimize both function and aesthetics. Case Presentation: We report a case of a 59-year-old female with a pigmented solid BCC of the right cheek. Wide local excision was performed, achieving histopathologically confirmed clear margins. The resultant defect, extending from the midface toward the nasolabial fold, was reconstructed using a cervicofacial advancement-rotation flap. Novelty and Rationale: The cervicofacial flap was selected due to its robust vascularity, excellent tissue match, and ability to provide a tension-free closure with minimal donor site morbidity. The flap was elevated in a subcutaneous and sub-SMAS plane to preserve vascularity, primarily based on the perforators from the facial and transverse cervical arteries. Meticulous dissection in the preauricular and cervical regions allowed for optimal mobilization without compromising facial nerve integrity. A lateral undermining technique enhanced flap rotation and reduced standing cutaneous deformities, ensuring a natural contour. Outcome: The patient’s postoperative course was uneventful, with complete flap survival and no complications. At the 6-month follow-up, there was no evidence of tumor recurrence, and the patient expressed high satisfaction with the functional and aesthetic results. Conclusion: This case highlights the cervicofacial flap as a versatile and reliable option for large cheek defects following on
Flap Design & Planning:
Design the flap along relaxed skin tension lines to optimize scar camouflage and minimize distortion.
Ensure the flap has an adequate arc of rotation and sufficient length to cover the defect without excessive tension.
Flap Elevation & Vascular Considerations:
Elevate the flap in the subcutaneous and sub-SMAS plane to preserve vascular supply from the facial artery perforators and transverse cervical artery.
Gentle handling of tissues prevents compromising flap perfusion and reduces the risk of venous congestion.
Mobilization & Inset:
Adequate undermining in the cervical and preauricular region is essential for tension-free closure.
Lateral advancement techniques help redistribute tension and avoid excessive pulling on the medial cheek.
Burrow’s triangles or back-cuts can be used strategically to improve flap contour and prevent dog-ear deformities.
Inadequate Undermining
Insufficient mobilization can lead to tension at the closure site, risking partial flap necrosis and wound dehiscence.
Overly Tight Closure
Excessive tension on the flap can cause distortion of surrounding structures (e.g., lower eyelid retraction, alar distortion).
Neglecting Vascular Integrity
Too deep dissection in the preauricular area risks injuring facial nerve branches.
Over-thinning the flap may compromise vascularity, especially in smokers or patients with vascular comorbidities.
Poorly Planned Scar Placement
A poorly positioned scar may result in visible contour irregularities, particularly if it crosses cosmetic subunits.
Older patients or those with sun-damaged skin may have reduced skin elasticity, requiring a more conservative undermining approach.
Patients with a history of smoking or diabetes may have a higher risk of flap necrosis and should be counseled accordingly.
BeforeAfterThe patient had no significant underlying medical conditions. Three years prior to presentation, she underwent a biopsy of a pigmented lesion on her right cheek, which was not followed by definitive treatment. Over time, the lesion progressively enlarged, prompting further evaluation and eventual surgical management.
The patient presented with a lesion on the right cheek that had progressively enlarged over the past month. Initially, the lesion appeared as a black spot resembling a mole, which first developed five years ago. Over time, it became pruritic, fragile, and prone to bleeding. The patient had previously undergone a surgical procedure; however, the pigmented lesion reappeared and continued to expand, eventually leading to ulceration.
Currently, the patient reports minimal pain but denies pruritus or fever. The patient has a history of prolonged sun exposure due to her occupation as a farmer during her younger years. On physical examination: A well-demarcated, pigmented nodular lesion measuring approximately 3cm x 4cm was observed on the right cheek, with areas of central ulceration and peripheral pearly borders. The lesion exhibited telangiectatic vessels on its surface and an indurated, slightly elevated margin. No signs of regional lymphadenopathy were noted, and no other suspicious lesions were identified on the face or body.
Although basal cell carcinoma (BCC) has a low risk of distant metastasis, it can exhibit locally invasive behavior, necessitating complete excision with histologically confirmed clear margins. A 5 mm clinical safety margin is generally recommended for well-defined BCCs, but larger margins may be required for more aggressive subtypes or ill-defined lesions. Given the tumor’s location on the cheek, careful reconstructive planning was essential to restore both function and aesthetics while minimizing donor site morbidity.
The cervicofacial flap was selected as the optimal reconstructive approach due to its ability to provide well-matched tissue with minimal tension. This flap offers a reliable blood supply primarily from perforators of the facial and transverse cervical arteries, ensuring robust vascularization. Unlike local advancement flaps, which may cause distortion of surrounding structures, the cervicofacial flap allows for a tension-free closure with excellent contour restoration.
Surgical Plan: The cervicofacial flap was designed as a rotation-advancement flap, elevated in a subcutaneous and sub-SMAS plane to maximize vascularity while preserving the integrity of the underlying facial nerve. Adequate undermining in the preauricular and cervical regions ensured sufficient mobilization and reduced tension at the closure site. To prevent standing cutaneous deformities, lateral undermining was performed, allowing the flap to drape naturally over the defect. Donor site closure was achieved with minimal scarring along relaxed skin tension lines, optimizing aesthetic outcomes.
Patient Information: The procedure was planned under general anesthesia due to the extent of the flap elevation and the need for meticulous dissection. A single-stage reconstruction was favored to minimize patient morbidity and recovery time. The patient was counseled on potential complications, including hematoma, infection, and partial flap necrosis, though the cervicofacial flap’s robust vascularity significantly reduces these risks. Given the literature and clinical experience, an excellent functional and aesthetic outcome was anticipated.
Outline the tumor with a 5 mm clinical safety margin for wide local excision.
Mark the cervicofacial flap extending from the preauricular region down to the lateral neck, ensuring adequate length for rotation and advancement.
Design the flap with a gentle curve along relaxed skin tension lines to optimize closure.
Plan for undermining in the subcutaneous and sub-SMAS plane to improve mobility.
Wide local excision of the tumor with full-thickness skin removal, extending into subcutaneous fat.
Ensure histopathological confirmation of clear margins via frozen section if available.
Assess the size and depth of the defect to determine the required flap mobilization.

Gradual advancement and rotation of the flap toward the defect.
Perform lateral undermining to enhance flap mobility and reduce tension.
Tension-free closure of the defect with layered suturing:
Deep dermal sutures (e.g., absorbable 5-0 Vicryl) to reduce tension.
Skin closure with fine interrupted sutures (e.g., 6-0 nylon) along natural skin creases.
Donor site closure with primary approximation, ensuring minimal distortion of surrounding structures.
Place a closed-suction drain.

Flap Monitoring:
Regular assessment of flap color, temperature, capillary refill, and turgor to ensure adequate perfusion.
Watch for signs of venous congestion (bluish discoloration, edema) or arterial insufficiency (pale, cool skin), especially in the first 48 hours.
Wound Care & Dressing:
Apply a light pressure dressing to minimize hematoma formation while avoiding excessive compression that may compromise flap circulation.
Consider placing a closed-suction drain in the undermined cervical region if significant dead space is present.
Instruct the patient to keep the surgical area clean and dry, with dressing changes as needed.
