Avicenna authored The Canon of Medicine, a principal medical textbook for over 600 years. Our primary goal is to systematically review and translate relevant portions of The Canon in its original Arabic and correlate to Sardo's 2014 translation, focusing on otolaryngology, to present an accurate representation of Avicenna's impact and highlight notable discrepancies. Secondarily, we aim to review the literature for citations discussing Avicenna's contributions to otolaryngology and identify misinterpretations. Notably, Avicenna may have described the shape of the cochlea 500 years before its believed discovery in humans by Eustachius (1552) and Falloppius (1561). There are also obscurities in Avicenna's descriptions of the etiology of epistaxis and airway management. It is essential to remain critical of historical texts and safeguard the accurate propagation of information to preserve the integrity of historical context and timelines of scientific advancement.

Objectives/hypothesis: The head and neck are two of the most common locations for cutaneous melanoma. We present the first population-based analysis of geographic differences in anatomic subsite, clinicopathologic and demographical traits, histopathologic subtype, treatment modality, and disease-specific survival (DSS) of cutaneous head and neck melanoma (CHNM).Study Design: Retrospective database analysis.Methods: The Surveillance, Epidemiology, and End Results database was queried for cases of CHNM reported between 2000 and 2013. Patients were grouped into East, Midwest, South, and West regions of the United States. Overall incidence, demographic traits, primary tumor site, clinicopathologic traits, histopathologic subtype, treatment modality, and DSS were compared among regions.Results: There were 49,365 patients with CHNM identified. The West (4.60) and the South (4.42) had significantly higher incidence (per 100,000) than the East (3.84) and Midwest (3.65) (P < .05). DSS was significantly different among regions (P < .0066). The East (5 years: 89.4%, 10 years: 84.1%) had the highest DSS rate, and the South (5 years: 87.0%, 10 years: 81.8%) had the lowest DSS rate. The Midwest (5 years: 88.4%, 10 years: 84.3%) and West (5 years: 88.3%, 10 years: 83.5%) had intermediate DSS. On multivariate analysis, the South had an elevated hazard ratio (1.17, 95% confidence interval: 1.05-1.30) when compared to the West.Conclusions: Geographic region may play a significant role in CHNM. Incidence is higher in the South and the West. Incidence, histologic subtype, treatment modality, and DSS vary among regions. DSS is lower in the South than the West, even after accounting for other major prognostic factors.Level Of Evidence: 4. Laryngoscope, 127:2763-2769, 2017. [ABSTRACT FROM AUTHOR]
