The business of rhinoplasty has undergone changes in keeping with increased competitive pressures locally, nationally, and internationally. Patient demands and progress in the field have abolished the 'cookie-cutter' nose, with patients now requesting extensive discussions and predictions with computer photoimaging. The R-Factor Question and The D.O.S. Conversation are effective tools in rhinoplasty consultations. These tools provide patients with the clarity of what surgery can do for their lives and help patients overcome the fear produced by the overwhelming amount of information available. By helping our patients achieve the next level of success in their lives, we guarantee ourselves a busy practice filled with happy patients. The rhinoplasty consultation is the key to beginning this relationship of success

OBJECTIVE: To determine the reliability of the House-Brackmann facial nerve grading scale in the setting of differential function across its branches. STUDY DESIGN: Prospective. SUBJECTS AND METHODS: Eleven physicians with different levels of clinical experience and three upper-level medical students were provided with digital video clips of 11 patients with differential facial nerve functioning, and asked to report facial nerve function as a traditional global score and as a regional score on the basis of the House-Brackmann scale for the forehead, eye, nose, and mouth. Agreements between the traditional global score and the regional scores, as well as inter-rater agreement, were analyzed. RESULTS: In patients with variable facial weakness, a single House-Brackmann score did not fully communicate facial function. The single House-Brackmann score most strongly correlated with the regional scoring of the nose/midface (59%), followed by the mouth (51%), eye (48%), and forehead (35%). Overall inter-reader reliability was relatively strong for the midface (kappa = 0.503) and global scores (kappa = 0.541), followed by the mouth (k = 0.419), the forehead (k = 0.330), and the eye (k = 0.302). There was a marked tendency for reader agreement to increase among those with more clinical experience. CONCLUSION: Regional assessment using the House-Brackmann grading scale more fully communicates facial function and increases in reliability with experience

BACKGROUND: In the past, surgeons believed that in order to eradicate regional disease, a radical or modified radical neck dissection was necessary. An evolution in surgical principles and the popularization of primary chemoradiation has raised the questions regarding the role of neck dissection and the extent of neck dissection following therapy. The aim of this study was to determine the efficacy of selective neck dissection (SND) for patients with N2 or N3 disease following treatment with primary radiation therapy or chemoradiation. METHODS: A retrospective review of 58 patients with stage III or IV head and neck squamous cell carcinoma was conducted. The primary sites included base of tongue (n = 15), hypopharynx (n = 12), tonsil (n = 16), larynx (n = 11), and unknown primary (n = 4). Definitive treatment consisted of either concomitant chemoradiation (67.2%) or external beam radiation therapy (32.8%). In the monotherapy group, all patients received a total curative dose of 66 to 72 Gy in once-daily fractions of 180 to 200 cGy. The combined chemoradiation group received a similar radiation schedule and a 4-day continuous infusion of cisplatin (20 mg/m(2)/day) and 5-fluorouracil (1000 mg/m(2)/day). A planned SND of levels II to IV was performed on all the patients 3 to 6 weeks after completion of definitive medical therapy. RESULTS: Seventy neck dissections were performed on 58 patients with advanced neck disease following radiation or chemoradiation. The median time of follow-up was 34 months (range, 9-71 months) following the neck dissection. Pathologically, 22.4% (13/58) of the patients had viable tumor cells identified in the neck dissection specimen. Seventy-two percent of the patients are currently alive, and 28% died as a result of distant disease, local or regional recurrence, or other causes. Of patients who died from distant disease, 11% had pathological evidence of residual tumor cells identified in the neck dissection specimen. Of patients who died from local or regional disease, 50% had pathological evidence of residual tumor cells identified in the neck dissection specimen. CONCLUSION: The rate of regional recurrence following SND is similar to reported rates following modified/radical neck dissection. This suggests that SND provides an appropriate surgical option for advanced neck disease in select patients following adjuvant therapy.

Lung cancer is the leading cause of cancer deaths world-wide. Recent advances in cancer biology have led to the identification of new targets in neoplastic cells and the development of novel targeted therapies. At this time, two targeted agents are approved by the FDA in advanced non-small cell lung cancer (NSCLC): the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) erlotinib, and the anitangiogenic bevacizumab. A third agent, cetuximab, which was recently shown to enhance survival when used with cisplatin and vinorelbine as first line therapy for advanced NSCLC, will likely be approved by regulatory agencies. With more than 500 molecularly targeted agents under development, the prospects of identifying novel therapies that benefit individual patients with lung cancer are bright.

Voice production involves precise, coordinated movements of the intrinsic and extrinsic laryngeal musculature. A component of normal voice production is the modification of pitch. The underlying neural networks associated with these complex processes remains poorly characterized. However, several investigators are currently utilizing neuroimaging techniques to more clearly delineate these networks associated with phonation. The current study sought to identify the central cortical mechanism(s) associated with pitch variation during voice production using event-related functional MRI (fMRI). A single-trial design was employed consisting of three voice production tasks (low, comfortable, and high pitch) to contrast brain activity during the generation of varying frequencies. For whole brain analysis, volumes of activation within regions activated during each task were measured. Bilateral activations were shown in the cerebellum, superior temporal gyrus, insula, precentral gyrus, postcentral gyrus, inferior parietal lobe, and post-cingulate gyrus. In the left hemisphere, activations in the medial and middle frontal gyri were also observed. Regions active during high pitch production when compared to comfortable pitch were evident in the bilateral cerebellum, left inferior frontal gyrus, left cingulate gyrus, and left posterior cingulate. During low pitch generation, activations were present in the inferior frontal gyrus, insula, putamen, and cingulate gyrus in the left hemisphere. The inferior frontal gyrus in the right hemisphere produced greater activity than the area of the left hemisphere during high and low pitch generation. These results suggest that a single-trial design is sensitive enough to begin to delineate a widespread network of activations in both hemispheres associated with vocal pitch variation
