Synchronous video laryngoscopy and sonography of the larynx in children.
Unlike laryngoscopy, laryngeal sonography is easily applicable, well tolerated by young children and less exhausting for the examiner. The aim of this study was to determine if sonography can adequately visualize the laryngeal structures and vocal fold movements of children. Synchronic video laryngoscopy and sonography of the larynx were performed in 35 children (aged 2-8 years) without a laryngeal disease. 10 investigators at differing stages of otolaryngological training were tasked with identifying vocal fold movement and specific anatomical structures after seeing (1) the sonography-only video and (2) the sonography video with a laryngoscopy video overlay. ⋯ Concerning the evaluation of the videos amongst the investigators: they identified >80 % of vocal fold movement and the targeted anatomical structures except the arytenoid cartilages (only up to 63 %), having the sonography only. In combination with the laryngoscopy video-overlay, investigator detection rates significantly improved (>90 % of vocal fold movement, p < 0.001; >90 % in most anatomical structures, (p < 0,001). Laryngeal sonography is a helpful diagnostic tool to identify laryngeal structures and the movement of the vocal folds in children.

With the exception of distant metastases, the presence of lymph node metastasis in the neck is accepted as the single most important adverse independent prognostic factor and an indicator of survival in squamous carcinoma of the head and neck. Neck dissection in its various forms is the standard surgical treatment for clinical, subclinical and subpathologic metastatic cancer to the neck. The pertinent literature from the beginning of the nineteenth century to the middle of the twentieth century was reviewed. ⋯ The greatest impetus to the status of this surgical procedure came from Martin and colleagues, who published a monumental report in 1951 of 1,450 cases that established the place and technique of radical neck dissection in the modern treatment of head and neck cancer. Neck dissection, for treatment of cervical lymph node metastases in head and neck cancer, was conceived and attempted in the nineteenth century, with some limited success reported by the end of that era. An effective operation was described and reported in the early twentieth century and evolved by the mid century into a fundamental tool in the management of patients with head and neck cancer.

Possible implication of Mdm2 as a prognostic marker in invasive laryngeal carcinoma.
Laryngeal squamous cell carcinoma is one of the most common malignant neoplasms of the head and neck. In Brazil, laryngeal tumors represent 2% of all cancers and are associated with approximately 3,000 deaths annually. Human papillomavirus (HPV) has been reported to play an important role in the etiology of laryngeal cancer. ⋯ Statistically significant differences (p < 0.05) in Mdm2 expression levels were observed in the in situ laryngeal carcinoma samples compared with the laryngeal carcinoma samples with metastasis. No statistically significant differences (p > 0.05) in either p53 or p27 expression levels were detected. These findings suggest that Mdm2 may be associated with the invasiveness and aggressiveness of laryngeal carcinomas.

Single dose of preoperative analgesia with gabapentin (600 mg) is safe and effective in monitored anesthesia care for nasal surgery.
This study was aimed to compare the intraoperative sedative and perioperative analgesic drug requirements and the incidences of postoperative side effects on the patients who received preoperative gabapentin or placebo. Sixty patients undergoing nasal septal or nasal sinus surgery were included. The patients received either 600 mg gabapentin (Group G) or placebo (Group P) orally, 1 h before surgery. ⋯ Time to first request for analgesic was 12.7 + or - 2.3 h in Group G, and 7.8 2.1 h in Group P (P < 0.0001). Total consumption of lornoxicam was lower in Group G (P < 0.004). We concluded that monitored anesthesia care combined with preoperative analgesia with a low dose of (600 mg) oral gabapentin is an efficient option with tolerable side effects for patients undergoing ear, nose and throat ambulatory surgery.

Surgical anatomy of the floor of the oral cavity and the cervical spaces as a rationale for trans-oral, minimal-invasive endoscopic surgical procedures: results of anatomical studies.
Over the past 10 years, several minimally invasive procedures for thyroid surgery have been developed. Because of extensive dissection in the thoracic and neck region, the name "minimal-invasive" is misleading. The aim of this study was to define a new trans-oral access to the cervical spaces especially to the thyroid on the basis of natural orifice surgery. ⋯ Therefore, the approach was modified by positioning the working trocars in the oral vestibule bilaterally. By this way, a road map for accessing all anterior cervical regions directly under the platysma muscle could be established and anatomical landmarks and areas of possible collateral damage could have been defined. This combined sublingual and bi-vestibular trans-oral endoscopic approach enables an easy access to all structures and spaces of the anterior neck region with respect to anatomical preformed layers neck, even to the thyroid as one of the more distant structures.
