[History of frontal sinus surgery and current view of the problem. Part 1]

Surgical treatment of inflammatory diseases of the frontal sinus is one of the biggest challenges of modern otorhinolaryngology. Close proximity of the frontal sinus and frontal sinus drainage pathways to the skull base, the orbit and the anterior ethmoid artery, great limitations with its visualization and instrumentation, and high risk of the frontal recess scarring cause difficulties in either endoscopic or external approaches to the frontal sinus. At the same time endoscopic approach to the frontal sinus is considered as preferred method of frontal sinusitis surgical treatment by majority of peers nowadays. The introduction of extended approaches to the frontal sinus pathology treatment with frontal sinus floor and interfrontal sinus septum drill-out as well as superior septectomy with common drainage pathway formation gave an opportunity to greatly decrease a rate of indications for external frontal sinus procedures. In this paper historical backgrounds of endonasal approaches to frontal sinuses are presented, current controversies in proper selection of extent and methods of the frontal sinus surgery are analyzed and endoscopic as well as external approaches to frontal sinuses are summarized.
