Objective: Vocal cord polyps are benign lesions of the larynx that are frequently seen and are treated surgically. These lesions generally develop in the free edge of the vocal cords, and form an incomplete glottal closure accompanied by irregular vibration of the vocal cords. In this study, the aim is to investigate the effect of surgery on vocal cord vibration in patients with vocal cord polyps who are treated with the endolaryngeal cold knife microsurgery. Method: Patients treated with endolaryngeal microsurgery at our clinic between 2014 and 2016, who were reported as vocal cord polyps by postoperative pathology result, and who regularly coming for follow-up examinations were included in the study. Using a scale which was first described by Hirano and Bless and modified and confirmed to be reliable in a study performed by Gürbüz et al., the preoperative and postoperative second month images of the patients were statistically compared. Results: 10 of the 25 patients included in our study were female (40%) and 15 were male (60%). In all patients, vocal cord polyps were unilateral, and were located in anterior 1/3 of the vocal cord in 12 patients (48%), and in medial 1/3 of the vocal cord in 9 patients (36%). It was determined that impaired vocal cord vibratory functions showed statistically significant recovery in the postoperative period compared to the preoperative period (p<0.05). Conclusion: Successful endolaryngeal cold knife microsurgery excision can correct impaired vibratory functions of vocal cords in patients with vocal cord polyps. [ABSTRACT FROM AUTHOR]

Objective: The objective of the study is to determine the incidence of occult lymph node metastasis detected in patients with head and neck cancer who applied to our clinic. Methods: Medical files of 107 patients who had been diagnosed as head and neck cancer between 2007 and 2012 were retrospectively examined. The patients who were accepted as N0 both clinically and radiologically at the time of diagnosis and those who had undergone neck dissection in addition to the treatment of primary tumor were included in the study. The patients were grouped based on the diagnosis of the primary tumor. Histopathology results of the patients and those with lymph node metastasis were documented. The proportion of the patients with occult lymph node metastases was calculated and primary tumor sites with a higher probability of occult lymph node metastases were determined. Results: A total of 64 patients were included in the study who were diagnosed as laryngeal (n=42; 65.6%), oral cavity (n=15; 23.4%), parotid gland (n=5; 7.8%), nasal cavity (n=1; 1.5%) and auricular (n=1; 1.5%) carcinomas. Histopathologically lymph node metastases were detected in patients with laryngeal (n=12; 70.5%), oral cavity (n=4; 23.5%) and parotid gland (n=1; 5.8%) carcinomas. Laryngeal cancers were subdivided into supraglottic (n=4), transglottic (n=7) and glottic (n=1) cancers. The highest rate of metastasis was detected in patients with transglottic laryngeal carcinoma. Conclusion: Occult lymph node metastasis is an important issue which should be kept in mind in cases with head and neck cancers. Location of primary tumor is an effective influential factor concerning this issue. As a result of this study, we thought that occult lymph node metastases are frequently seen in patients with transglottic laryngeal cancers. [ABSTRACT FROM AUTHOR]
