Objectives/Hypothesis: Severe vocal fold lesions such as vocal fold sulcus, scars, and atrophy induce a communication disorder due to severe hoarseness, but a treatment has not been established. Basic fibroblast growth factor (bFGF) therapies by either four-time repeated local injections or regenerative surgery for vocal fold scar and sulcus have previously been reported, and favorable outcomes have been observed. In this study, we modified bFGF therapy using a single of bFGF injection, which may potentially be used in office procedures.Study Design: Retrospective chart review. Methods: Five cases of vocal fold sulcus, six cases of scars, seven cases of paralysis, and 17 cases of atrophy were treated by a local injection of bFGF. The injection regimen involved injecting 50 mg of bFGF dissolved in 0.5 mL saline only once into the superficial lamina propria using a 23-gauge injection needle. Two months to 3 months after the injection, phonological outcomes were evaluated.Results: The maximum phonation time (MPT), mean airflow rate, pitch range, speech fundamental frequency, jitter, and voice handicap index improved significantly after the bFGF injection. Furthermore, improvement in the MPT was significantly greater in patients with (in increasing order) vocal fold atrophy, scar, and paralysis. The improvement in the MPT among all patients was significantly correlated with age; the MPT improved more greatly in younger patients.Conclusions: Regenerative treatments by bFGF injection-even a single injection-effectively improve vocal function in vocal fold lesions.
Objective/Hypothesis: Tracheoesophageal diversion (TED) can prevent damage to the respiratory system in patients with swallowing disorders and/or repetitive aspiration pneumonia; however, TED may cause the loss of phonation. Our previous study demonstrated that TED with tracheoesophageal puncture (TEP) prevents aspiration while retaining phonation. In this study, we aimed to further evaluate the feeding status and phonation of patients who underwent TED with TEP to verify the reproducibility of this procedure.Study Design: Case series study. Methods: We retrospectively reviewed the medical records of 11 patients who underwent TED with TEP for intractable aspiration from February 2017 to August 2019 at Fukuoka Sanno Hospital. We evaluated the preoperative penetration aspiration score (PPAS), daily activities, preoperative and postoperative food intake level scale (FILS) score, nutrition route, maximum phonation time(MPT), and postoperative communication method.Results: The study population included 10 men and 1 woman (mean age, 66 years; range, 44-81) with a PPAS of 6.8 ± 1.0. The FILS score changed from 2.1 ± 0.5 preoperatively to 7.5 ± 2.0 postoperatively (paired t-test, P < .05), while the MPT changed from 7.9 ± 4.1 to 10.3 ± 4.2 s (paired t-test, P = .9). Preoperatively, a gastric fistula (eight patients [73%]) was the main nutrition route, followed by a gastric tube (two patients [18%]). Postoperatively, the main nutritional route for eight patients (73%) was oral, while the remaining three patients (27%) used the oral route occasionally. All patients maintained laryngeal phonation function, and eight (73%) used only laryngeal phonation for communication.Conclusions: Patients with intractable aspiration who wish to retain phonatory function should be advised to undergo TED with TEP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
