Management of Facial Telangiectasias

Evaluation and Diagnosis

The American Academy of Pediatrics recommends evaluating facial telangiectasias to rule out underlying conditions, and if no associated pathology is found, they can be treated with pulsed dye laser (PDL) if they cause aesthetic or psychosocial concern 1
It is essential to determine if telangiectasias are localized or generalized, and associated with other signs or symptoms 2
A complete clinical evaluation should be performed, including the pattern of distribution, age of onset, and associated characteristics that may indicate underlying disorders 3
Ultrasound is the recommended initial imaging modality if hemangiomas or other vascular lesions are suspected 2, 4

Infantile hemangiomas in the involution phase can be considered in the differential diagnosis of facial telangiectasias 5
Cutaneous mastocytosis, especially telangiectasia macularis eruptiva persistens, is another condition to consider in the differential diagnosis 6

If telangiectasias are asymptomatic and do not cause significant functional or aesthetic problems, observation is a reasonable option 7
Parents should be educated about the condition and its possible evolution 3

Pulsed dye laser (PDL) is the treatment of choice for persistent facial telangiectasias 1
The advantages of PDL include preferential absorption of light by hemoglobin, efficacy for superficial telangiectasias, and minimal risk of scarring 1
Technical considerations for PDL treatment include using a wavelength of 595 nm, larger spot sizes (up to 10 mm) with higher fluences, and longer pulse durations to treat larger vessels 1

In children, laser treatment generally requires sedation or topical anesthesia 1
Possible complications of laser treatment include atrophic scarring, hypopigmentation (especially in individuals with darker skin), and ulceration (rare) 1, 4, 6

If telangiectasias are associated with other signs or symptoms suggesting a systemic disease, referral to a specialist is recommended 6
If lesions are extensive or cause significant aesthetic concern, referral to a specialist is also recommended 2
If laser treatment or other therapeutic modalities are required, referral to a specialist is necessary 1

Periodic evaluation is necessary to monitor the evolution of lesions 3
Reevaluation is required if new lesions or associated symptoms appear 3
Assessment of the psychosocial impact, especially during adolescence, is essential 3
