To evaluate mechanisms of discrepant responses to the nondepolarizing muscle relaxant rocuronium among normal and injured facial nerve-innervated orbicularis oris and tibial nerve-innervated gastrocnemius, and to provide information for the proper use of muscle relaxants to balance evoked electromyography (EEMG) monitoring and immobility in general anesthesia. ⋯ The affinity of AChR at end plates and different number of AChR per unit fiber cross-sectional area may be the mechanisms for differential sensitivities to neuromuscular blockers between facial nerve-innervated muscles and somatic nerve-innervated muscles. The lower EEMG responses in the impaired facial nerve-innervated muscles may result from the lower AChR density at end plates compared with the normal facial nerve-innervated muscles.

Alcohol abuse is associated with an increased incidence of postoperative complications in surgical patients and is a significant risk factor for the development of head and neck cancer (HNCA). We sought to determine the relationship between alcohol abuse and in-hospital mortality, postoperative complications, length of stay, and costs in HNCA surgery. ⋯ Alcohol withdrawal is associated with an increase in postoperative medical and surgical complications, length of hospitalization, and hospital-related costs in HNCA surgical patients. Aggressive measures to prevent the development of AWS in patients who abuse alcohol are warranted.

Numerous professional societies, clinical practices, and hospitals provide Internet-based patient education materials (PEMs) to the general public, but not all of this information is written at a reading level appropriate for the average patient. The National Institutes of Health and the US Department of Health and Human Services recommend that PEMs be written at or below the sixth-grade level. Our purpose was to assess the readability of endoscopic sinus surgery (ESS)-related PEMs available on the Internet and compare readability levels of PEMs provided by three sources: professional societies, clinical practices, and hospitals. ⋯ Current Internet-based PEMs related to ESS, regardless of source type, were written well above the recommended sixth-grade level. Materials from the hospitals/university-affiliated websites had lower readability scores, but were still above recommended levels. Web-based PEMs pertaining to ESS should be written with the average patient in mind.

Diagnostic transnasal flexible endoscopy (TNFE) is a commonly used office procedure in otolaryngology. Currently there is a paucity of data on the impact of TNFE on physiologic parameters. This is relevant with the advent of office-based endoscopic procedures. The goal of this study is to measure the impact of topical decongestion, anesthesia, and diagnostic TNFE on vital signs: systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR), and oxygenation (O(2) sat). ⋯ Diagnostic TNFE and topical lidocaine can have an impact on physiologic parameters; however, these changes are unlikely to be clinically significant.

No specific otoplasty method has been considered as the absolute standard in patients with prominent ears showing thick and strong auricular cartilage. ⋯ The conchal cartilage-grafting adhesion technique creates a naturally shaped smooth antihelix, allowing the prominent ear to predictably and permanently set back. We believe that the method is indicated in adult patients showing thick and strong auricular cartilage.
