Background and Objective : Vocal fold augmentation by injectable material under direct visual control is an easy and simple operation. However, when autologous fat or bovine collagen is used, the resoiption creates a problem. And autologous fascia is debating about absorption now days. We previously reported on the one year results of injected autologous auricular cartilage for volumetric augmentation in paralyzed canine vocal cord. This study evaluates the long-term histomorphologic results of injected autologous auricular cartilage for the augmentation of the paralyzed canine vocal fold at two year. Material and Methods . A prospective trial of autologous cartilage augmentation of vocal cord in animal model. Three dogs were operated upon. A piece of auricular cartilage was harvested from the ear and minced into tiny chips with a scalpel. Fat was harvested from inguinal area and minced with a scalpel. The minced cartilage and fat-paste (0.2ml) was injected using a pressure syringe into the paralyzed thyroarytenoid muscle using direct laryngoscopy. Three animals were sacrificed at 2 years. Each subject underwent laryngectomy and serial coronal sections of paraffin blocks from the posterior vocal fold were made. Results There was no significant complication perioperatively and during follow-up. The injected cartilage which appeared to have lost viability existed in the vocalis muscles until 24 months. Fibrotic change was exhibited in the surrounding injected cartilage. Conclusion : The autologous auricular cartilage graft is well tolerated and may be very effective material for volumetric augmentation on paralyzed vocal cord.

Sonoring is caused by the repeated obstructions of versatile upper air way structure during sleep and is known as a kind of disease entity varing from simple snoring to obstructive sleep opnea syndrome(OSAS) which can cause serious cardiopulmonary complications due to its hypoxic pathophysiology. It has been reported that over 30% of middle-aged person have the problems of snoring and its accompanied symptomes and signs. Cephalometric measurements, frequently used to measure sella-nasion-subspinale(SNA) and sella-nasion-supramentale(SNB) angles, can provide the informations about the posterior airway space(PAS), the mandibular plane(MP) and the position of hyoid bone. These informations are useful in determining the therapeutic modalities of the snoring and OSAS patients. However, with conventional routine upright position, it does not represent the actual images of obstructive mechanism during sleep but only show the images of awaken normal upper airway anatomy. Therefore we have taken dual images of a routine upright lateral and a supine cephalometric view to compare both.

Background and Objectives: The periorbita has been regarded as the crucial structure in decision of orbital exenteration in the patients with paranasal malignancies. The mass beyond the thickened periorbita on T2-weighted images was considered to be a positive finding of orbital invasion. The purpose of this study is to evaluate the oncological safety of endoscopic removal of infiltrated tumor onto the periorbita but not transgress into orbital fat. Patients and Methods: Five patients of advanced maxillary cancer, showing bony orbital wall destruction and infiltration onto the periorbita but not transgress into orbital fat, underwent partial or total maxillectomy. Preoperative Cl and MRI were performed in all cases and compared with intraoperative findings. The successful dissection between tumors and periorbita using bipolar nasal coagulation forceps and tumor forcep was performed under endoscopy. Results: The mean age was 54.4 (41-74) years. All tumors of five patients originated from maxillary sinus and extended to involve multiple different subsites according to AJCC (2002, 6^(th) ed.) Histopathology included four squamous cell carcinomas and one adenoid cystic carcinoma. Follow-up ranged from 30 to 121 months (mean 53.6 months). All cases showed no local recurrence on the periobita after endoscopic removal. One patient had local recurrence in the pterygopalatine fossa and the other had in the neck. Conclusion: Endoscopic removal of infiltrated tumor onto the periorbita using microdebrider, bipolar nasal coagulation forceps and tumor forceps can be oncologically safe technique in advanced maxillary cancer infiltrated onto the periorbita but not invaded into orbital fat.
