ABSTRACT
OBJECTIVES: A persistent insufficiency of glottal closure is mostly a consequence of impaired unilateral vocal fold movement. Functional surgical treatment is required because of the consequential voice, breathing and swallowing impairments. The goal of the study was to determine the functional voice outcomes after medialization thyroplasty with using autologous septal cartilage from the nose. METHODS: External vocal fold medialization using autologous nasal septal cartilage was performed on 15 patients (6 females and 9 males; age range, 30 to 57 years). Detailed functional examinations were performed for all the patients before and after the surgery and this included perceptual voice assessment, laryngostroboscopic examination and acoustic voice analysis. RESULTS: All the patients reported improvement of voice quality post-operatively. Laryngostroboscopy revealed almost complete glottal closure after surgery in the majority of patients. Acoustic and perceptual voice assessment showed significant improvement post-operatively. CONCLUSION: Medialization thyroplasty using an autologous nasal septal cartilage implant offers good tissue tolerability and significant improvement of the subjective and objective functional voice outcomes.

Objective To investigate a safe and effective method to correct the over rotation of nasal tip in rhinoplasty. Methods 16 cases, including 11 of primary and 5 of secondary over rotation of nasal tip, were corrected with strut grafts using autologous cartilage or combined with Medpor to reconstruct the supporting structures underneath to improve the upward and forward strength of the nasal tip in order to increase the nasal height and to correct the over rotation of of nasal tip. The shield and cap grafts were also used for the patients whose nasal tip were too low, with vertical dome division technique. Results 16 cases were corrected satisfactorily, the nasal lip angles were normal and there were no complications by follow-up from 6 months to 1 year. Conclusion It is necessary to provide powerful forward and upward strength to correct the over rotation of nasal tip effectively and safely, and proper cartilage grafts can im-prove the height of the nasal tip and correct the over rotation of the nasal tip further.
