[PMID: 38106372 PMCID: PMC10723904 DOI: 10.1155/2023/8817274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 08/29/2023] [Accepted: 11/03/2023] [Indexed: 12/19/2023] Open
Abstract
Venous malformation (VM) originates from a congenital venous network disorder, configuring about 40% of the vascular anomalies that occur in the head and neck region. The usage of diode lasers in the treatment of VM is associated with various advantages, such as short operating time and few postoperative complications. Nevertheless, for larger and deeper VM treatment, it may require more than one session for the complete resolution of the lesion. Laser surgery for oral VM may induce heat accumulation due to excessive irradiation causing adverse events postoperatively, including pain and ulcer formation with scarring. In this clinical case, it was recommended to use the leopard technique (LT) to reduce the lesion size, evaluate the remaining unhealed lesion, and apply different laser techniques to obtain the complete resolution of the lesion.

Abstract
BACKGROUND Infantile hemangioma (IH) is a common vascular tumor in female infants, which can lead to aesthetic issues and facial scarring. This study aimed to investigate the inhibitory effects and underlying mechanisms of 755 nm long-pulsed alexandrite laser on IH. METHODS Hemangioma endothelial cells (HemECs) were exposed to 755 nm long-pulsed alexandrite laser to evaluate its impact on cell proliferation and apoptosis. A patient-derived xenograft model was established to assess the inhibitory effects of laser treatment on IH in vivo. RESULTS In vitro, 755 nm long-pulsed alexandrite laser effectively suppressed the proliferation of HemECs and induced cell apoptosis. Laser treatment significantly inhibited the volume and weight of tumors, accompanied by significant downregulation of vascular endothelial growth factor A (VEGFA), vascular endothelial growth factor receptor 2 (VEGFR2), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) expression levels in both hemangioma cells and tumors. Additionally, laser treatment resulted in the conversion of VEGFA165a to VEGFA165b. TUNEL staining demonstrated increased apoptosis in tumor cells after laser treatment, along with upregulation of cleaved caspase-3 and Bax, and downregulation of Bcl-2. CONCLUSION In addition to the principle of selective photothermal decomposition, modulation of the VEGF/PI3K/Akt axis may serve as a potential mechanism for IH treatment using a long pulse-width 755 nm laser. This sheds valuable light on the molecular mechanisms underlying IH pathogenesis and potential therapeutic targets while providing a theoretical basis for the safe and efficient management of proliferative IH using laser therapy.

Abstract
Long-pulsed neodymium:yttrium-aluminum-garnet (Nd:YAG) lasers have recently been used for the treatment of vascular lesions refractory to conventional vascular lasers. The aim of this study was to evaluate the clinical efficacy and safety of long-pulsed Nd:YAG laser treatment for vascular disorders. Laser irradiation was performed using two approaches: the 532 nm Nd:YAG laser was used to irradiate the dorsal skin fold in mice and the 1064 nm Nd:YAG laser was used to irradiate the leg of mice without skin incision. The specimens were observed immediately after laser treatment using a laser Doppler perfusion imaging system. Red blood cell (RBC) extravasation and hemorrhage were observed using the hematoxylin and eosin stain. The diameter of blood vessel under 30 μm was disrupted with a laser pulse at a fluence of 12 J/cm2 and a wavelength of 532 nm regardless of pulse duration. The veins and arteries of approximately 1 mm in size were ablated with laser pulses at a fluence of 140 J/cm2 and above and a wavelength of 1064 nm. Selective photopyrolysis can be achieved with either 532- or 1064 nm Nd:YAG laser pulses in vascular diseases based on the depth and size of the vessel.

Abstract
Purpose Assessment of the clinical effectiveness and safety of 755-nm long-pulse alexandrite laser combined with 0.5% timolol maleate eye drops in treating thicker infantile hemangioma (IH). Materials and Methods Retrospective analysis of IH treated with 755-nm long-pulse alexandrite laser and topical timolol in the Second Affiliated Hospital of Wenzhou Medical University from October 2019 to October 2020. Seventy-eight cases were included, with a five-week laser treatment interval. Treatment status was documented during the 35 weeks before each treatment, the effect was assessed at the visual analog scale (VAS), and side effects were recorded. During the 6-month follow-up period, the recurrence and residual skin lesions were monitored. The relationship between IH thickness, treatment duration and VAS was analyzed. Results Among the 78 children with hemangioma, 4 children were treated with a combination of propranolol, fractional laser and cinnamyl alcohol injection due to poor curative effect. Finally, the lesions were effectively alleviated. At the 5th, 15th, 25th, and 35th weeks of treatment, the average VAS of 74 children were 3.56 ± 1.20, 4.61 ± 1.43, 5.63 ± 1.60, and 6.63 ± 1.72, respectively. We analyzed VAS in different thickness groups with Repeated Measures Analysis of Variance(RMANOVA). The results show that the VAS of the thickness 2–3 mm and 3–5mm groups were higher than the 5–7mm and 7–8mm groups (F group = 440.54, P <0.05, F time = 448.31, P <0.05). During the 6-month follow-up period, none of the 74 children relapsed and the residual skin lesions gradually vanished. Conclusion Combined treatment of IHs with a 755-nm long-pulse alexandrite laser and 0.5% timolol maleate eye drops which has apparent clinical efficacy and safety reduce residual skin lesions and decrease the IH recurrence rate.

Abstract
Vascular anomalies are subdivided into vascular tumors (hemangiomas) and vascular malformations. They are frequently located in the head, neck, and oral cavity. They are common complaints reported in patients seeking treatment for aesthetic or functional issues. However, recent advances in the diagnosis and management of these lesions are improving treatment strategies. This review provides both basic and up-to-date knowledge on the most common vascular anomalies encountered by practitioners. Due to the wide variability of treatment options which often generates debate, this paper work aims to provide a comprehensive approach of these lesions based upon current concepts and practical clinical experience. Our article is about 4 patients who had consulted for one or several purplish, elevated, well limited and soft lesion. These lesions was not painful, but worrying for patients. Therapies for VAs continue to generate a dilemma for oral surgeons. Several treatment options were reported, including conventional surgery with or without adjunctive preoperative embolization, and drug therapies, such corticosteroids, intralesional injection of corticosteroids and intralesional injections of sclerosing agents. All of these therapeutic approaches carry a high risk of severe side effects such as scars, pain, and bleeding [7]. Nowadays, advances in the use of lasers have allowed doctors an effective treatment with minimal side effects [9]. All our cases described in this article were done by Pr Haitami, using the 980 nm Diode laser, and a complete healing was observed in about 8 months at the most. The laser is therefore a great help in the management of this type of lesion.

Early tongue carcinomas (clinical stage I and II): echo-guided three-dimensional diode laser mini-invasive surgery with evaluation of histological prognostic parameters. A study of 85 cases with prolonged follow-up. Lasers Med Sci 2019; 35:751-758. [PMID: 31834561 DOI: 10.1007/s10103-019-02932-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 11/27/2019] [Indexed: 12/15/2022]
Abstract
The management of patients with early stage (cT1-T2) tongue squamous cell carcinoma without clinicoradiologic evidence of neck node metastasis (cN0) has been widely debated over the last 3 decades and still remains controversial. Nevertheless, the identification of patients with low-stage tumours at high-risk for occult cervical metastases is imperative before planning treatments of primary tumours, as well as that of prognostic markers which may possibly select those patients who may benefit of additional workup after surgery in view of the high metastatic potential of the primary tumour. The pre-surgical evaluation of tongue malignant primary tumour (for assessing lateral and deep margins) along with diode laser surgery (with accurate incision, bleeding-free and with reduced/absent post-surgical complications) may lead to a more conservative but equally decisive surgical treatment, also with a greater patient compliance. We studied 85 consecutive cases of cT1-T2 N0 tongue squamous cell carcinoma who had been managed by the following diagnostic/therapeutic protocol: pre-operative high definition ultrasound examination for the evaluation of size and depth, followed by three-dimensional surgical excision by diode laser (wavelength of 800 ± 10 nm, output power of 8 W in continuous wave, flexible optic fibre of 320 μm in contact mode) and detailed histological analyses of well-established prognostic parameters (tumour grade, thickness, depth, front of infiltration and surgical margins) with statistical analysis. No post-surgical photobiomodulation was performed. Overall, 58.82% of patients were stage I, 18% stage II, and the most frequent histotype was squamous cell carcinoma (97.64%). Large nests invasion pattern was observed in 64 cases, expansive pattern in 9, invasion in single cells in 12; front of invasion involved the muscle in 62 cases, vessels in 6, nerves in 15; peritumoural vascular invasion was assessed in 6 patients and perineural invasion in 15. Selective neck lymphadenectomy was performed in 9 cases, and clinically occult node metastases were detected in two cases. At follow-up, 78 patients (98.73%) were alive and free of disease, one patient experienced tumour-related death, while the remaining 6 died for non-disease-related causes. All the histological prognostic parameters were statistically significant (χ2 test; p = 0.05), thus leading to a prognostic weight classification with a three-tiered stratification. On the bases of these results, the authors maintain that the reported diagnostic/therapeutic protocol, including the pre-operative echo-guided three-dimensional evaluation, the following diode laser mini-invasive surgery for tumour excision and the histological examination along with the proposed three-tiered stratification of histological prognostic parameters may allow proper management of clinical stage I and II early tongue carcinomas.

Abstract
Objective: To determine optimal settings for use of diode lasers to treat vascular malformations in the head and neck. Background: Diode lasers are generally accepted as effective tools to treat vascular malformations in the head and neck, yet there are no standardized treatment protocols for this treatment approach. Settings for these lasers, in addition to laser type and size and lesion depth are important variables for designing appropriate treatments for vascular malformations. Materials and methods: Vascular venous malformations (VeMs) were classified into five groups according to high-definition ultrasound measurements of superficial dimensions (<1, 1-3, and >3 cm) and lesion extension depth (≤5, and >5 mm). Using a 800 ± 10 nm diode laser for surgical procedures, we treated lesions by two different approaches: trans-mucous/cutaneous photocoagulation (8 and 12 W pulsed wave for cutaneous and mucosal lesions, respectively) and intralesional photocoagulation using a laser set to 13 W in the pulsed wave modality to treat both cutaneous and mucosal lesions. Results: We treated 158 vascular VeMs. According to preoperative staging, there were 52 lesions in Group A (superficial dimension <1 cm), 28 in Group B1 (superficial dimension from 1 to 3 cm, extension depth ≤5 mm), 16 in Group B2 (superficial dimension from 1 to 3 cm, extension depth >5 mm), 42 in Group C1 (superficial dimension >3 cm, extension depth ≤5 mm), and 12 in Group C2 (superficial dimension >3 cm, extension depth >5 mm). All Group A lesions showed complete healing after a single laser treatment, whereas 7%, 10%, 12%, and 16% of lesions classified in Groups B1, B2, C1, and C2, respectively, required further treatments. Conclusions: The laser settings defined in this study were associated with a reduced number of laser applications needed for effective treatment of vascular VeMs. Moreover, the cooling of irradiated tissues, together with prolonged application of a topical regenerative gel, provided good treatment acceptability, reduced the number of postoperative complications, and promoted faster healing of covering tissues.
