Tonsillectomy is the one of operation that is performed the most commonly in otolaryngology field. Many changes that include range of voice, tone, voice quality and resonance were made by tonsillectomy. Sometimes, any patients taken tonsillectomy has suffer from these voice problem after tonsillectomy. However there are less study for these problems until now. Then, we studied to find the anatomical findings that affected the voice quality when tonsillectomy was performed. We evaluated the voice in 2 groups, one is the group showed the normal pharyngeal space by using the transnasal fiberscopy, the other is group showed medially bulging tonsil at pharyngeal cavity by using same method, with perceptual evaluation, nasalance score, nasality, oral formant and nasal formant. We used the computerized speech analysis system, the nasometer and the spectrogram in the CSL program. We could not find any differences in perceptual evaluation between two groups. But objective measures were provided. Nasalance score and nasality on the nasometric analysis were increased significantly and oral formant on the spectrogram was changed singnificantly after tonsillectomy in Group 2. Authors thought medially bulging tonsil in the pharynx is able to affect the voice quality after tonsillectomy when we evaluted through the nasal cavity by the using of fiberscopy and this evaluation would be important especially in singers.

With recent developments in medical technology and the introduction of various types of lasers, the role of fiberoptic laryngeal laser surgery (FLS) in laryngology has been significantly expanded. FLS are typically performed under local anesthesia, and patients may return to normal activities immediately after the procedure. This corresponds to the current trend of minimally invasive surgery and may limit unnecessary general anesthesia, reduce medical costs, and increase patient compliances. Main indications of FLS procedure were vocal polyp, recurrent respiratory papillomatosis, vocal fold granuloma and vocal fold dysplasia. In this review, we discuss practical tips and unique value of FLS.

The first case was a 20 year old female who has been suffered from epigastric pain, and anorexia for 2 years. A thumb tip sized pulsion diverticulum 4cm above the esophagocardial junction was elicited by esophagogram and on exploration. A diverticulectomy with long esophagocardiomyotomy was performed. The second case was a 30 year old house wife who has had postprandial epigastric pain for 2 months accompained with frequent vomiting. Fiberscopy and esophagogram showed epiphrenic diverticulum of the esophagus. Same operative procedures were carried out and obtained a good result as first case. The third case was a 55 year old house wife who was admitted to this Chest Surgery Department because of regurgitation and intermittent vomiting for approximately 3 months. Esophagogram showed a large epiphrenic diverticulum of the esophagus. On exploration, a tennis ball sized pulsion diverticulum was found on the anterolateral wall of the esophagus. A partial esophagectomy including the diverticulum and esophagoesophagostomy was performed. The specimenshowed some erosive changes of the mucosal surface of the diverticulum and also the esophagus suggestive of diverticulitis and esophagitis. She has been satisfactory result until 4 months postoperatively, when she developed regurgitation and epigastric pain. Esophagogram showed stenosis of the operative site. Readmission and esophageal dilatations were done and improved without any problem. Epiphrenic or supradiaphragmatic diverticulum of the esophagus is a rare condition. Pathophysiologically, the conditions accompanied the spasm of the esophagus, many authors prefered the procedures of a diverticulectomy plus long esophagocardiomyotomy rather than simple diverticulectomy or esophagectomy and esophagoesophagostomy. Here we report the cases and reviewed the literatures.
