Use of blue laser in a patient with postop restenosis of the choana after multiple surgical interventions for congenital choanal atresia

One of the most common complications following surgical interventions in nasal cavity is synechiae and scarring, which often leads to restenosis, particularly in cases of choanal atresia. Laser technologies, especially blue laser (wavelength 445 nm), represent a promising opportunity in rhinology for addressing these complications. Objective: to study the effectiveness and safety of blue laser for nasal synechiae and stenosis surgery in patients with congenital choanal atresia after multiple surgical interventions. In ENT department of Veltishev Institute 4 children have undergone choanal reconstruction following multiple attempts of choanoplasty. A clinical case of a 6-year-old girl diagnosed with bilateral complete choanal atresia, who underwent six surgical interventions within two years and was admitted with complete choanal restenosis is presented. The most common cause of restenosis after surgery for hoan atresia is the formation of synechiae in the surgical area. Traditional dissection of the synechiae in most cases leads to repeated stenosis. To reduce the recurrence rate in the patient, the authors used a blue laser. The blue laser demonstrated high effectiveness in the surgical treatment of postop restenosis, minimizing surgical trauma, preventing recurrences, and improving the patient’s quality of life. The results confirm the feasibility of using lasers in rhinology as a preferred method for treating restenosis and enhancing respiratory function.
