Introduction: Treatment of oral melanomas utilizes the surgical excision-resection (Culp et al., 2013) and/or radiation therapy (Proulx et al., 2003), chemotherapy with carboplatin (Brockley et al., 2013), immunotherapy (Ottnod et al., 2013). Treatment based on surgical excision is usually palliative (Freeman et al., 2003). Aims: In the literature even though there are data concerning the prognosis of oral melanomas in dogs after surgery, are missing data after laser excision. Taking into account these findings we wished to present our experience regarding three cases of oral melanoma recurrence and immediate and long term laser surgery results. Materials and Methods: The casuistry consisted of three dogs with recurrent oral malignant melanomas, subjected to surgical reintervention. The initial diagnosis was melanotic melanoma in stage I or II. The animals were brought back at different time intervals from originally excision with electric scalpel. Before reintervention, dogs were subjected to clinical, paraclinical exam and biopsy. Excision of the tumor mass was made with an optical fiber hawing a diameter of 400µm, at a power of 10W and a wavelength of 940 nm with a diode laser. At 1, 2, 3, 6 and 12 months after laser reintervention the dogs were reexamined. Results: Average time in which appeared canine oral melanoma relapse was 58.6 days. After reexamination all cases where reinstatement in stage I. Operators times were held in conditions of comfort with wide access, minimum bleeding, effective hemostasis. After surgery at 24 hours on the intervention place a slight local redness, without swelling and bleeding was observed. Palpation revealed initially also a slight local sensitivity which completely disappeared in 48 hours. There were no grasping and chewing disturbances. Macroscopic healing occurred in 7-9 days. At last recheck performed at 12 months there were no evidences of tumour recurrence or metastasis. Conclusion: Diode laser excision of oral malignant melanoma in dogs can be an alternative palliative procedure to invasive surgical resection procedures. The average of free recurrence and metastasis time after laser surgery has exceeded 360 days in these three cases.

“…Furthermore, heat-related complications, such as delayed healing, increased scar formation or temporary oedema might exacerbate airway stenosis. Finally, the use of flammable materials in an atmosphere of high oxygen concentration makes airway fire a feared complication (Sullins 2002, Hansen & Sundset 2006, Du Rand et al 2011, De Lorenzi et al 2015. In veterinary medicine, diode laser therapy has recently been reported for the treatment of canine epiglottis chondrosarcoma (De Lorenzi et al 2015 ); to our knowledge there are no previous reports concerning tracheal tumour management.…”

“…Leonard described excision of one‐third of the epiglottis along its abaxial borders for management of epiglottic entrapment in 3 dogs, which resulted in complete resolution of inspiratory dyspnea in all cases. More extensive epiglottectomy techniques including subtotal/total epiglottectomy have previously been reported in only 4 dogs, 2 for management of recurrent ER and 2 for epiglottic chondrosarcoma . No major postoperative complications were reported in any case, although follow‐up time was not clearly stated in 2 dogs .…”

Objective To report intraoperative and major postoperative complications in dogs treated surgically for epiglottic retroversion (ER), compare the incidence of major postoperative complications between procedures, and report survival of surgically treated dogs. Study design Multi‐institutional retrospective study. Sample population Fifty dogs treated with 78 procedures. Methods Medical records of dogs diagnosed and surgically treated for ER from 2003 to 2017 at 11 institutions were reviewed. Complications were divided into intraoperative and major postoperative complications. Results Intraoperative complications occurred during 2 of 78 (2.6%) procedures. Thirty‐six major postoperative complications were documented in 22 dogs after 36 of 74 (48.7%) procedures. Postoperative complications occurred after 7 of 12 (58.3%) nonincisional epiglottopexy, 23 of 43 (53.5%) incisional epiglottopexy, 2 of 4 (50%) partial epiglottectomy, 2 of 12 (16.7%) subtotal epiglottectomy, and 2 of 3 (66.7%) other surgical procedures. Epiglottopexy failure was the most common major postoperative complication. The incidence of major postoperative complications did not differ between procedures (P = .1239), although, when combined, epiglottopexy procedures (30/55) had a higher incidence of complications than epiglottectomy procedures (4/16; P = .048). Thirty (60%) dogs were alive at a median of 928 days (range, 114‐2805), 8 (16%) were lost to follow‐up after 411 days (range, 43‐1158), and 12 (24%) were dead/euthanized after 301.5 days (range, 3‐1212). Median survival time was not reached after a median of 716 days. Conclusion Although intraoperative complications were uncommon, major postoperative complications were common, especially after epiglottopexy procedures. Clinical significance Although surgical treatment of ER is associated with a high rate of major postoperative complications, especially epiglottopexy procedures, long‐term survival can be achieved.
