Successful resection of laryngocele with temperature-controlled plasma technique aid on endoscopy: A case report.

INTRODUCTION AND IMPORTANCE

There are many ways to manage laryngocele, including external approach and endoscopic approach. The endolaryngeal technique has gained popularity and many of the authors reviewed have begun to use this technique for the treatment of internal laryngoceles duo to the advent of microlaryngoscopic surgery and the CO2 laser during the last two decades. In this article, we describe the management of a large congenital laryngocele with temperature-controlled plasma technique (coblation) aid on endoscopy and along with review of literature.

PRESENTATION OF CASE

a 19-year-old female was admitted to our hospital with a 5-month history of poor breathing, accompanied by sleep snoring, obstruction during swallowing, foreign body sensation after eating. Laryngoscopy revealed a cystical mass lie in the left cavum laryngis and epiglottis, and caused laryngeal stenosis.

CLINICAL DISCUSSION

Low-temperature plasma technology facilitates tissue resection at temperatures ranging from 40 to 70 degrees Celsius, thereby minimizing thermal injury and preserving the integrity of local mucosal structures. Laryngocele resection was performed via microlaryngoscopy using a temperature-controlled plasma technique (coblation). The patient's course during the follow-up period was uneventful, with no evidence of disease recurrence at the 4-year postoperative follow-up evaluation.

CONCLUSION

Microlaryngoscopy involving the use of a coblation is a safe therapeutic procedure for the treatment of internal laryngoceles. Airway management is very important for success of operation of endoscopic approach.
