Distal chip versus fiberoptic laryngoscopy using endoscopic sheaths: diagnostic accuracy and image quality.
Laryngeal visualization is the hallmark in the diagnostic approach of laryngeal disease. In addition to fiberoptic techniques, digital distal chip technology has been developed to improve visualization. Endoscopic sheaths are used in daily clinical practice to prevent cross-contamination. ⋯ Image quality was validated better in DCL as compared to FOL (p < 0.05). Interrater agreement in identifying laryngeal disease was 1.5 times higher in DCL (κ = 0.44) as compared to FOL (κ = 0.29). In this study, reflecting daily clinical setting using sheathed endoscopes, DCL is identical to FOL regarding diagnostic accuracy, but DCL is superior to FOL in image quality and interrater reliability.

Relative frequency of chronic postoperative pain in patients operated for chronic otitis media.
Chronic postoperative pain may lead to physical disability and psychosocial distress. In this longitudinal observational study, for the first time we evaluated the relative frequency of chronic postoperative pain in patients operated for chronic otitis media (COM) at two university hospitals. Patients were questioned about pain at the site of the surgical incision 3-6 months after the operation, and again 3 months after the first visit. ⋯ A significant decrease in the average score of VAS was observed from 5.18 to 2.64 within 3 months (P = 0.0001). Statistically significant correlation was observed between chronic postoperative pain and age, sex, acute postoperative pain and history of Irritable Bowel Syndrome or migraine, but after multivariate analysis, only the age group and severe acute post-operation pain were effective on incidence of chronic post-operative pain. In conclusion, surgery for COM is followed by chronic pain in about 32 % of patients, and some risk factors for the development of chronic postoperative pain after this surgery exist, including age and severe acute post-operation pain.

Quantitative study on endoscopic endonasal approach to the posterior sino-orbito-cranial interface: implications and clinical considerations.
The posterior sino-orbito-cranial interface is a critical area in the skull base since it represents a gateway to deeper vital regions. Quantification of the surgical freedom for any given point/area is an objective method for comparing in a reproducible way different surgical approaches. Three freshly injected cadaver heads (six sides) were dissected under the magnetic navigation control system. ⋯ Laterally extended lesions require an anteromedial maxillotomy, while more medially located lesions can be managed by means of a posterior septectomy. When addressing the posterior sino-orbito-cranial interface, the transnasal binostril approach and anteromedial maxillotomy both increase the SF. The choice between them depends on exact position, relationship and clinical behaviour of the lesion to treat.
