ABSTRACT: To apply the technique of injection of a combination of autologous fascia lata and fat into the vocal fold via the cricothyroid gap for unilateral vocal fold paralysis and to evaluate the therapeutic effect in 12 patients who underwent the procedure.
Retrospective analysis of 12 patients.
A mixture of autologous fascia lata and fat was injected into the thyroarytenoid muscle of the paralyzed vocal fold in 12 patients.
Videolaryngostroboscopy was performed to observe the changes to the vocal fold. The patients' phonatory function before and after surgery was assessed by computerized acoustic analysis and by blinded perceptual evaluation.
Videolaryngostroboscopy demonstrated that the paralyzed vocal folds in these patients were pushed medially after the procedure. Statistically significant improvements were found in the perturbation measurements (jitter and shimmer), harmonics to noise ratio, and maximum phonation time. Ratings by a panel of voice experts also showed each voice to be statistically significantly improved after the procedure. No complications were noted.
A combination of autologous fascia lata and fat injected into the vocal fold for unilateral vocal fold paralysis is a safe and effective therapy.

ABSTRACT: To explore the intranasal surface localization of the lacrimal sac in endoscopic dacryocystorhinostomy.
Fifteen adult cadavers (30 sides) were studied, the data of projection position of the lacrimal sac on the lateral wall of nasal cavity were measured.
In 2/3 cadavers, the lacrimal sac is located above the axilla of the middle turbinate, and 1/3 lies below it. A majority of the lacrimal sac (2/3) are located below the entry point of the common lacrimal canaliculus, about 1/3 lies above it. Inner canthal ligament projects on the middle of the lacrimal sac, almost equal to the level of common lacrimal canaliculus. Thirty-two cases (thirty-nine sides) of chronic dacryocystitis were followed-up > 6 months after operation. Thirty-five sides were cured, 2 sides improved and 2 sides ineffective. The cure rate was 89.8%, improve rate 5.1% and ineffective rate 5.1%, respectively, and the total effective rate was 94.9%.
The central position of dacryocystorhinostomy should be 0.2 cm above the front of the axilla of the middle turbinate, to make an curved mucous membrane incision 0.8 cm above and 0. 4 cm below the front of the axilla of the middle turbinate and bone ostium about 1.2 cm x 1.0 cm. It is the best position in endoscopic dacryocystorhinostomy. Locating the inner canthal ligament with a bayonet type forceps to find the projection of lacrimal sac is also a simple and easy method.
