Complicated Infantile Hemangioma of the Lip: Outcomes of Early versus Late Resection

Practical surgical technique using the SMISS approach for lip reduction in involuted lip infantile hemangiomas

BACKGROUND

Lip infantile hemangiomas tend to show less volumetric regression and are more susceptible to visible sequelae in the involuted stage. Some of them still require surgical management after propranolol therapy. This study aimed to evaluate the efficacy and safety of the Stepwise, Multi-Incisional, and Single-Stage (SMISS) approach applied to lip reduction for those with involuted lip hemangiomas.

METHODS

A retrospective review was performed to evaluate patients with lip hemangioma who received previous propranolol treatment and underwent the aforementioned procedure. Demographic characteristics, lesion morphology, and medical history were reviewed. The Visual Analog Scale was applied to assess the postoperative appearance. Complications within 12 months postoperatively were recorded.

RESULTS

A total of 18 patients with lip hemangioma were eligible. All patients received oral propranolol therapy before surgery, with treatment duration ranging from 6.0 to 23.0 months. Their age at surgery ranged from 2.5 to 9.0 years. The median Visual Analog Scale scores were 8.0, ranging from 4.0 to 10.0. No severe complications were reported.

CONCLUSIONS

This modified technique based on the SMISS approach has proven reliable and effective in improving the aesthetic outcome for involuted lip infantile hemangiomas. Practical surgical techniques still play an important part in the propranolol era.

Intralesional betamethasone versus oral propranolol for localized infantile hemangiomas of the lip

Infantile hemangiomas (IHs) of the lips are associated with an increased risk of incomplete involution and ulceration, causing disfigurement. Treatment with oral propranolol (OPT) has credible efficacy but takes months to complete. Thus, this study aimed to investigate the efficacy of intralesional betamethasone injection (IBI) as an alternative treatment for protruding localized IHs of the lips. To investigate the efficacies of OPT and IBI, we designed a prospective, noninferiority, parallel-group study. The primary outcome assessed was treatment response rate. Secondary outcome assessments included lesion size changes and surgical rate. Additionally, complication rates and treatment durations of OPT and IBI were compared. The treatment response rate of IBI was not inferior to that of OPT (95.7% vs. 76.0%, respectively; a difference of 19.7%, 95% confidence interval [CI], -4.4% to 41.6%). The average surgical rate in the IBI group was significantly lower than that in the OPT group (8.7% vs. 40%, respectively; p = 0.012), and the average duration of treatment for IBI was shorter than that of OPT (2.1 months vs. 6.3 months, respectively; p < 0.001). There were no severe adverse drug events in either group. If not managed properly, small, localized lip IHs may cause disfigurement in a child. Our study demonstrated that IBI is as effective as OPT in treating protruding localized lip IHs. Moreover, IBI treatment has a shorter duration and lower surgical rate than OPT. With proper care, IBI is an effective treatment modality for small and localized lip IHs.

Does Oral Propranolol Improve the Final Outcome of All Involuted Infantile Hemangiomas? A Matched Retrospective Comparative Study

BACKGROUND

Oral propranolol can effectively activate and accelerate infantile hemangioma (IH) involution; however, could the final outcome of oral propranolol treatment for IHs commensurate that of spontaneous involution?

OBJECTIVE

This study aimed to investigate the long-term therapeutic effect of oral propranolol for IHs.

METHODS

We present an individual matching comparative study with (1) oral propranolol therapy for mixed and deep IHs on the lips, nose, and parotid and (2) lesion type- and lesion location-matched untreated IHs as controls. Patients' follow-up photographs were assessed by 3 surgeons blinded of their treatment. Outcome measures were the quantification of the degree of sequelae ranging from 1 to 4 and the age at which IH achieved involution arrest.

RESULTS

Ten groups of oral propranolol and untreated patients with matched lesions were assessed. Average age at which lesions stabilized and reached no change in appearance was 1.7 years old and 6.3 years old for propranolol group and untreated group (t = 5.663, P < 0.001). There was no significant difference in the quantified degree of sequelae for oral propranolol group and untreated group upon follow-up (1.60 vs 1.40, respectively; t = 1.259, P = 0.240).

CONCLUSIONS

Oral propranolol therapy accelerates IH involution but does not have a superior effect than spontaneous involution on the overall outcome of problematic IHs.

Infantile Hemangiomas of the Lip: Complications and Need for Surgical Intervention

Background:

Infantile lip hemangiomas are challenging to manage due to the functional and aesthetic importance of the lips. Hemangiomas in this region may lead to significant complications including ulceration, feeding difficulties, and lip contour distortion requiring surgical intervention.

Methods:

A retrospective chart review of children with focal lip hemangiomas treated at our institution between January 2000 and December 2016 was conducted. Patient demographics, lesion characteristics, complications, treatments, and outcomes were collected. Lesions were classified based on depth (superficial, deep, or mixed depth), vermillion border involvement, and location.

Results:

One hundred and two patients with focal lip hemangiomas were identified; 45.1% were managed expectantly, 43.1% were treated medically, and 18.6% required surgery. Residual lip contour deformity following involution was the most common complication (26.5% of patients). Ulceration during the proliferation phase was reported in 14.7% of patients, leading to significant feeding difficulties in 9.8% of patients. All ulcerations occurred in lesions with a superficial component. None of the patients with superficial lesions underwent surgery; 27.1% of patients with deep or mixed depth hemangiomas required surgical treatment to restore lip contour.

Conclusions:

Lip hemangiomas have high rates of complications that seem to be related to lesion morphology and phase of growth. Ulceration occurs during the early proliferative phase and is most frequently associated with mixed depth hemangiomas. Residual lip contour deformities are identified in the involution phase; presence of a deep component is the primary factor in predicting the need for surgical intervention in these patients.

Evidence-Based Medicine in the Treatment of Infantile Hemangiomas

Over the past decade, the treatment of infantile hemangiomas has undergone dramatic breakthroughs. This review critically evaluates the latest literature that supports the myriad treatment options for infantile hemangiomas. It chronicles the fading role of steroid therapy and evolution of propranolol use as the major treatment modality. Although propranolol is helping this disease become more of a medical disease and less of a surgical dilemma, the report also reveals a continued search to find nonsystemic treatment options. In summary, this is an evidence-based medicine review for the treatment of infantile hemangiomas.

Eighteen cases of soft tissue atrophy after intralesional bleomycin a5 injections for the treatment of infantile hemangiomas: a long-term follow-up

Pingyangmycin is a commonly used drug in China for the treatment of infantile hemangiomas (IHs) and vascular malformations. Also known as bleomycin A5, it has a similar chemical structure to bleomycin. The side effects of bleomycin include swelling, erythema, fever, headache, hyperpigmentation, ulceration, allergic reactions, and pulmonary fibrosis. We conducted this retrospective study to identify the correlation between bleomycin A5 injections and soft tissue atrophy. We performed a retrospective chart review of all patients with IHs who had this treatment and presented with soft tissue atrophy in our department from January 2011 through July 2013. Eighteen children with IHs (14 girls, 4 boys) were included in this study. The average age was 8.6 ± 3.8 years. All of the atrophied deformities were located at the injection site. Thirteen (72.2%) were located on the upper lip, three (16.7%) on the nose, and two (11.1%) on the cheeks. Seventeen (94.5%) received their first injection at the age of 1 or 2 months. The mean number of injections was 3.5 ± 1.6. The mean interval between injections was 1.2 ± 0.3 months. Eight of 18 patients (44.4%) had ulceration after injection. Intralesional bleomycin A5 injection is not safe for the treatment of IHs because it may lead to soft tissue atrophy. Other safer treatments, such as oral propranolol, should replace this treatment.

A retrospective study to classify surgical indications for infantile hemangiomas

Infantile hemangiomas (IHs) spontaneously involute, but some leave contour deformities necessitating surgical correction. There is a paucity of data reviewing predictive risk factors associated with a need for surgery to guide clinicians when counseling parents. Patients undergoing IH resection by a single surgeon from August 2004 to August 2011 were reviewed to determine patient (age, gender, birth history) and IH characteristics (size, location) associated with surgical intervention. Data were compared to published data from the Hemangioma Investigator Group (HIG). Statistical analysis was performed using Student's t-test, odds ratio, and logistic regression analysis. Out of 196 referred patients, 112 underwent surgery. There was a female preponderance (3.5:1). Two-thirds of patients (64.9%) first presented to the surgeon at ≤2 years of age, but most underwent surgery between 2 and 3 years (52.7%; average lag time, 11 months). 18 patients underwent surgery at ≤1 year of age. IH patients with preterm birth history had increased risk for needing surgical intervention (odds ratio 2.124, CI 1.31-3.44; p < 0.0012). A majority (84.7%) of resected IHs were located on the head or neck, significantly higher than the distribution from the HIG data (62.2%; p < 0.0001). Resected head and neck IHs were smaller than those below the neck (average, 8.85 cm(2) vs. 22.35 cm(2), p = 0.017). Preterm birth is associated with higher risk for requiring surgical intervention. IHs on the head and neck are more likely to be removed when compared to those below the neck, and at a smaller size threshold.

Complex vascular anomalies

The classification system for vascular anomalies now used by experts worldwide comprises two distinct disease entities that differ in their biologic and pathologic features: vascular tumors and vascular malformations. Vascular tumors include infantile and congenital hemangiomas, tufted angiomas, and kaposiform hemangioendotheliomas. Infantile hemangiomas, the most common vascular anomaly, generally have a predetermined life cycle (proliferation and subsequent involution). GLUT-1, a glucose transporter, is a marker for these specific lesions during all phases of development. Vascular malformations are classified according to their vascular tissue of origin and include capillary, venous, arteriovenous, lymphatic, and mixed malformations. Complex lymphatic malformations and complex mixed malformations, which may have most vascular components, are the most difficult vascular malformations to successfully treat. These lesions are present at birth and often expand or grow in response to trauma, infection, or hormonal changes. Imaging advancements have enabled more accurate assessments and improved management of vascular anomalies. In addition, many lesions are now being managed with targeted pharmacologic therapy. Propranolol and steroids are used for complex or disfiguring tumors, and new anti-angiogenesis inhibitors such as sirolimus are selectively used to treat lymphatic and venous lymphatic malformations that are poorly responsive to sclerotherapy, embolization, and surgical excision. Multimodal therapies are often essential for complex lesions and require the combined expertise of an interdisciplinary team.
