Background and Objectives Granular myringitis is troublesome for otologist because uncertain etiology and often been overlooked due to vague clinical symptoms and signs. The ideal treatment is elusive. Our study was to investigate the clinical characteristics of granular myringitis and analyzing the effect of the two different strategies, including carbon dioxide laser (CO2 laser) and caustic agent cauterization to manage granular myringitis. Study Design: Retrospective review Subjects and Methods One hundred and thirty patients with granular myringitis receiving treatment at a single medical center from July 2009 to January 2018 were enrolled. We retrospectively reviewed the charts and surgical records. The main two different strategies to manage focal refractory granular myringitis were analyzed, including carbon dioxide laser and caustic solution. We also recorded the clinical course and determine which strategy is better. Results One hundred and thirty patients with granular myringitis were enrolled. 47/130 (36.1%) had previous otologic procedures. Frequent ototrrhea is the most common symptom (66.1%). Posterior-inferior quadrant is the most common site of involvement (58%). The successful rate of CO2 laser, caustic agent were 94.9% and 79.2%. The recurrence rate was comparable between CO2 laser and caustic agent. No major complication was found in either individual group. Conclusion: Otologic procedure may be a predisposing factor of focal chronic myringitis. Ear drops had poor efficacy compared to other treatments. It can be apply only on minor and fresh symptom cases. In this study, we suggest CO2 laser can be the first line treatment, especially for the troublesome or refractory GM cases, which had the higher successful rate and less complication comparing to caustic agent cauterization.

Ingrown toenails are one of the most common pathologic conditions encountered in podiatric medical practice. Many methods of treatment for ingrown toenails have been used and studied, including chemical matrixectomies, surgical approaches, and CO2 laser ablation. This study is a retrospective review of a new technique that consists of resection of the involved nail matrix using a No. 15 blade and controlled cauterization using a CO2 laser. The technique was performed on 381 painful ingrown toenails, and all of the patients were followed up postoperatively for an average of 34 months. The results showed minimal pain, a low recurrence rate, rapid return to activity, and good cosmesis. (J Am Podiatr Med Assoc 95(2): 175–179, 2005)

Abstract Background Acne scars, is a challenge for dermatologists, despite having multiple treatment modalities like microneedling, dermabrasion, Fractional CO2 Laser, dermal fillers, etc. However, monotherapy has been hardly satisfactory because of the polymorphism seen with the scars. Objective Comparison between microneedling with platelet rich plasma versus Fractional carbon dioxide laser with platelet rich plasma in treatment of atrophic post acne scars. Patients and methods This study was carried out in department of dermatology, venereology and andrology, in Kobry El-Kobba Military complex during the period (from September 2018 to July 2020 ) on 20 patients of both sexes aged from 20 to 60 years old presenting with Goodman and Baron Grade II, III, IV acne scars . Results The study revealed a statistically significant difference (p = 0.017) between Goodman and Baron scar grades on the right side of the face before and after treatment indicating that microneedling with platelet rich plasma was effective in improving acne scars. Also, there is a statistically significant difference (p = 0.010) between Goodman and Baron scar grades on the left side of the face before and after treatment, indicating that fractional CO2 laser with platelet rich plasma was effective in improving acne scars. Conclusion and recommendation Further controlled and randomized studies are needed to validate our findings in a larger cohort of patients and longer follow up. Also, number of sessions might be more than 3 sessions.

Purpose Because of its affinity for water-based tissues, carbon dioxide (CO2) laser has become an instrument of choice for treating oral mucosa conditions, ranging from inflammatory to malignant lesions. The aim of this work is to systematically evaluate the outcomes of laser surgery over a wide range of lesions, while providing a solid and reproducible protocol for CO2 laser surgery in the outpatient management of oral lesion. Methods Seventy-eight patients underwent 92 laser outpatient procedures for treatment of a wide range of benign and malignant lesions. We performed 60 removals, 11 exeretic biopsies, 15 vaporizations, and 3 vaporization/removal combined. We analyzed laser parameters applied for each technique and provided a systematic evaluation of surgical results. Results No problems occurred intraoperatively in any of the patients. Five patients complained marginal pain, while 3 patients had postsurgery bleeding. All treatments were successful, with the notable exception of 3 relapsing verrucous proliferative leukoplakias and an infiltrating squamous cell carcinoma of the tongue requiring radicalization. We did not record any adverse reactions to drugs or lesions due to laser action. Concordance between clinical diagnosis and pathology results was at 94.8%. Conclusions Our data indicate that CO2 laser is a solid choice for outpatient treatment of oral lesions. This technique grants painless and almost bloodless treatment, with negligible recurrence rates. Providing a solid reference for laser settings and operative techniques could provide a foundation for further exploring this tool while offering the basis for a positive comparison between different surgical techniques and options.

Limited mouth opening (LMO) is a frequent complication of systemic sclerosis (SS). Its management is complex and there are limited treatment options. We report four patients with SS and severe LMO [interincisal distance (IID) <30 mm] treated with pulsed carbon dioxide (CO2) laser. Pulsed CO2 laser treatment of the white lips was performed after all patients had signed a written informed consent in the absence of alternative treatment. Treatment was carried out under locoregional anaesthesia using a Sharplan 30C CO2 laser in the Silk Touch® resurfacing mode. One to three laser sessions were performed at intervals of 8-12 months between sessions. Assessments were performed at 3 and 12 months with measurement of the IID using a ruler, calculation of the Mouth Handicap in Systemic Sclerosis (MHISS) scale and global evaluation by the patients. Adverse events were also reported. In all four patients, an improvement in IID occurred 3 months after the first session with a mean gain of +5 mm (range: 2-7). At 12 months, a mean gain of +8.5 mm (range: 7-10) in IID was observed. The MHISS score decreased by a mean of -14 (range: 11-17). All patients showed improvement of lip flexibility or mouth opening, allowing better phonation and mastication and easier dental care. Adverse effects were transient erythema and/or dyschromia. CO2 laser appears to be effective and well tolerated in the improvement of LMO in SS.

Epulis fissuratum is a pseudotumor growth located over the soft tissues of the vestibular sulcus caused by chronic irritation from poorly adapted dentures. Treatment indication for these lesions is surgical excision with appropriate prosthetic reconstruction. The hemostatic capacity of carbon dioxide (CO2) laser is well described in the literature as a useful tool in oral surgery, especially in patients with clotting disorders. This paper presents a case of a 72-year-old female patient referred to the 'Nossa Senhora da Conceição de Valongo Hospital' at Porto, Portugal, with a massive growth of vestibular oral mucosa in the mandible and maxilla associated with ill-fitting dentures, suggestive of epulis fissuratum. The patient was taking antithrombotic medication. The lesions were excised with CO2 laser, and no significant complications, such as hemorrhage, pain, swelling or infection, were recorded. Twenty days after surgery, both areas were completely reepithelizaded. Prosthetic rehabilitation and function were achieved with the fabrication of new maxillary and mandibular dentures. Follow-up 1 month and 1 year after treatment revealed the areas free of recurrence. The use of CO2 lasers is currently the gold standard in the excision of this type of lesion, especially in patients with hemorrhagic diathesis or under antithrombotic therapy.

AIM: The aim of the study was to confirm the efficiency and safety of the fractional CO2 laser in skin renewal and to check the possibility of having a synergistic effect in patients who besides carbon dioxide laser are treated with PRP (platelet-rich plasma) too.MATERIAL AND METHODS: The first group (Examined Group 1 or EG1) included 107 patients treated with fractional CO2 laser (Lutronic eCO2) as mono-therapy. The second group (Control Group or CG) covered 100 patients treated with neither laser nor plasma in the same period but subjected to local therapy with drugs or other physio-procedures under the existing protocols for treatment of certain diseases. The third group (Examined Group 2 or EG2) treated 25 patients with combined therapy of CO2 laser and PRP in the treatment of facial rejuvenation or treatment of acne scars.RESULTS: Patient’s satisfaction, in general, is significantly greater in both examined groups (EG1 and EG2) (p < 0.001). It was found the significant difference between control and examined group from the treatment in acne scar (Fisher exact two tailed p < 0.001). Patients satisfaction with the treatment effect in rejuvenation of the skin is significant (χ2 = 39.41; df = 4; p < 0.001). But, patients satisfaction from the treatment with HPV on the skin was significantly lower in examined group (treated with laser), p = 0.0002.CONCLUSION: Multifunctional fractional carbon dioxide laser used in treatment of patients with acne and pigmentation from acne, as well as in the treatment of scars from different backgrounds, is an effective and safe method that causes statistically significant better effect of the treatment, greater patients’ satisfaction, minimal side effects and statistically better response to the therapy, according to assessments by the patient and the therapist.

SummaryPolymethylmethacrylate (PMMA) cement is routinely used in a number of surgical procedures performed on human beings and animals. As the use of PMMA increases in veterinary medicine, the need for its removal during “revision” surgeries also increases. Common indications for removal of PMMA are infection, aseptic loosening, and fracture of the cement. Polymethylmethacrylate cement is often applied in areas of the body where typical mechanical methods of removal are dangerous or impossible. Cement placed near the spinal canal for the treatment of caudal cervical malformation-malarticulation syndrome or deep within the femoral medullary canal for total hip prostheses are examples. The ability to safely and easily remove cement should lower intraoperative complication rates associated with revision surgeries.The vaporization efficiency for removal of PMMA cement for three carbon dioxide laser modalities (continuous wave only, with Swift-Lase™ attachment, and with Fiberlase™ wave guide) were determined, as well as heat transferred to periosteal surface during PMMA cement vaporization, and gross pathology to the cortical bone at the maximum vaporization efficiency power. Cefazolin sodium was added to half of the samples to determine if the ablation ablation rate of PMMA would be affected. The C02 laser with wave guide was the most efficient modality for vaporization at 25 watts, and produced significantly less heat transfer to the periosteal surface than the heat of polymerization of the PMMA cement. Cefazolin sodium appeared to slightly decrease the vaporization efficiency, and all of the lasers produced gross and histologic lesions to the bone.Three laser types were compared for their ability to efficiently and safely remove polymethylmethacrylate (PMMA) cement. Vaporization rates were determined. The most efficient wattage for each laser modality was used to compare the heat transferred during PMMA removal as well as the pathology created by application of each laser modality to the cortical bone. The CO2 laser with wave guide at 25 watts was the most efficient modality for vaporization of PMMA cement, and produced significantly less heat transfer to the periosteal surface than the CO2 laser and the CO2 laser with Swift-Lase™.

AbstractThis study compares the relative thermal damage caused by a surgical CO2 laser and the Erbium: YAG laser when used to incise the human vocal fold in vitro. Results show that charring is completely eliminated when using the Erbium: YAG laser. The depth of coagulative necrosis adjacent to an incision is reduced from 510 ±m(µ 75) using the CO2 laser to 23 ±m(µ 12) using the Ebrium: YAG laser and at the base is reduced from 125 ±m (µ 45) using the CO2 laser to 12 ±m (µ 8 ) using the Erbium: YAG laser. The potential advantages regarding post-operative healing after laryngeal surgery are discussed.
