It is a radical technique. With delicate modified instruments, this technique can improve considerably the function because of the advances in technology that emphasize mucosal preservation

Objective: To investigate the long-term outcomes of patients with unilateral vocal fold paralysis resulting in dysphonia treated with lateral vocal fold autologous fat injection. To analyze the factors that may affect the long-term efficacy of the procedure. Methods: From July 2003 to June 2020, 163 patients (86 males and 77 females), aged 9-73 years (mean (34.50±12.94) years) with unilateral vocal fold paralysis resulting in dysphonia underwent transoral laryngoscopic injection of autologous fat into the lateral vocal folds. Subjective auditory perception assessment (GRBAS scale), objective acoustic assessment, voice handicap index (VHI) evaluation and stroboscopic laryngoscopy were compared before and after the surgery. Patients were followed up for 1 to 18 years, with median follow-up time of 6 years. SPSS 22.0 software was used for statistical analysis. Results: Of 163 patients, 17 patients (10.4%) had mild hoarseness (G1) and 146 patients (89.6%) had moderate to severe hoarseness (G2-3). Stroboscopic laryngoscopy revealed an arch-shaped vocal fold on the affected side, fixed in the paramedian position or abduction position, with obvious glottic closure fissure. Postoperatively, voice recovered to normal (G0) in 139 patients (85.3%), mild hoarseness (G1) in 18 patients (11.0%) and moderate hoarseness (G2) in 6 patients (3.7%). Of these, 131 patients (80.4%) showed significant improvement in hoarseness, 29 patients (17.8%) showed mild improvement and 3 patients (1.8%) showed no significant improvement in hoarseness. Objective acoustic parameters of Jitter, Shimmer, NHR and MPT improved significantly, as did VHI scores. Stroboscopic laryngoscopy showed medialization of the affected vocal folds, improved vocal fold closure and normal or nearly normal vocal fold mucosal waves. With a fat injection volume of 3.0-4.5 ml, the patient's subjective auditory perception scores of G, R, B and A improved more significantly within 3 months after surgery, and both VHI and MPT were significantly better since 1 year after surgery. With bilateral vocal fold injection, the B and A scores improved significantly from 1 month postoperatively compared to unilateral injections(unilateral vs. bilateral injection 1 month post-operation, t_{B scores}=1.42,t_{A scores}=1.51,P<0.05). Conclusions: The long-term efficacy of autologous fat injection in the paraglottic space for the treatment of unilateral vocal fold paralysis was stable. The efficacy of the surgery was related to the amount of fat injected, unilateral or bilateral of the injection.

Vocal cord paralysis is one of the most serious anesthetic complications related to endotracheal intubation. The practitioner should take extreme care, as bilateral vocal cord paralysis can obstruct the airway and lead to disastrous respiratory problems. There have been many papers on bilateral vocal cord paralysis after neck surgery, but reports on such a condition after lung surgery are very rare. We report a case of bilateral vocal cord paralysis detected after removal of a double-lumen endotracheal tube in a 67-year-old patient who underwent wedge resection by video-assisted thoracoscopic surgery. We also note that he recovered spontaneously without complications within a day.

Pediatric vocal ford paralysis is a vocal cord movement disorder caused by damage to the pediatric laryngeal motor nerves.It is mainly characterized by voice, breathing,and swallowing difficulties,and in severe cases,it can lead to choking in affected children. Currently, the diagnosis and treatment of this condition pose a significant challenge for pediatric otolaryngologists, as the goal is to minimize damage to the vocal folds and laryngeal framework.In order to standardize the diagnosis and treatment of pediatric vocal cord paralysis, the Pediatric Otolaryngology Committee of the Chinese Medical Association,in collaboration with multiple children's medical centers nationwide, have formulated this consensus document.
