Clinical Effects of Radiofrequency Coblation for Adult Laryngopharyngeal Vascular Lesions

Abstract

Objective To explore the feasibility and efficacy of transoral radiofrequency coblation surgery (TRS) in the treatment of adult laryngopharyngeal vascular lesion (LVL). Methods A total of 15 patients with LVL were retrospectively studied, including 11 capillary lesions and five cavernous lesions (there was one case with two separate lesions). All of the lesions were treated with TRS alone (capillary lesion) or with a combination of TRS and sclerotherapy (cavernous lesion). The treatment efficacy was evaluated according to the modified Achauer criteria: grade 1, no change in size; grade 2, a decrease of < 50% in size; grade 3, a decrease of ≥ 50% but < 100%; and grade 4, the disappearance of the lesion with no recurrence for at least 6 months. Results The surgical procedures were successfully completed in all patients. According to the modified Achauer criteria, the treatment outcomes were grade 4 for 10 capillary lesions and one cavernous lesion; grade 3 for one capillary lesion and one cavernous lesion; grade 2 for one cavernous lesion; and grade 1 for two cavernous lesions, respectively. No complications related to the surgery, including bleeding, dysphagia, and infections, occurred after treatment. Conclusion The TRS is an effective treatment option for LVL, especially for patients with laryngopharyngeal capillary lesions. Level of Evidence 4 Laryngoscope, 131:566–570, 2021

Clinical Characteristics, Classification, and Management of Adult Nasopharyngolaryngeal Hemangioma

“…In our patient cohort, therapeutic effects were evaluated by clinical manifestations, physical examination, nasal fiberendoscopy, and/or postoperative imaging examination (magnetic resonance imaging [MRI]). According to the evaluation criteria in previous publications, 14,20,21 four levels of therapeutic efficacy were listed: level I, tumor was unchanged or even increased in size; level II, tumor significantly reduced in size, but less than 1/2; level III, tumor reduced by more than 1/2, but did not disappear completely; level IV, tumor totally disappeared without functional loss and recurrence at least 6 months. All patients were scheduled to clinic observations 1 month after surgery, and then followed-up every 3 to 6 months; 96.9% (n = 94) of patients had a full-range postoperative follow-up and intact clinical information was gathered; 3 patients were lost in our follow-up due to the changes of contact ways.…”

“…5 Due to its rarity, scattered case reports regarding the clinical management of ANPLH in nasopharynx, oropharynx, hypopharynx, and/or larynx are available. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] However, no large-scale investigations focusing on ANPLH have been published. Therefore, our current study aims to clarify the clinical features, classification, and therapeutic strategies of patients with ANPLH based on a relatively large sample size, which will deepen our understanding of ANPLH and standardize the clinical management for these patients.…”

“…Previous study indicates that ANPLH is a residual lesion from the infancy and childhood 5 . Due to its rarity, scattered case reports regarding the clinical management of ANPLH in nasopharynx, oropharynx, hypopharynx, and/or larynx are available 4–19 . However, no large‐scale investigations focusing on ANPLH have been published.…”
