2019年2月1日 · The frontal sinus outflow tract, also known as the frontal sinus drainage pathway, are the structures through which mucus from the frontal sinus flow normally. Depending on the references, the term is used variably, including. 1. Huang BY, Lloyd KM, DelGaudio JM, Jablonowski E, Hudgins PA.

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele f …

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis.

The purpose of this pictorial essay is to provide a visual guide to the frontal sinus drainage pathway (FSDP), associated anatomic structures, and normal variations in sinus anatomy (Figs 1 – 9). Suggested readings provide more detailed descriptions of paranasal sinus anatomy and terminology for further study (1 – 9). F ig 1.

2017年12月1日 · Direct sagittal para-midline MDCT scan in bone window. It shows the frontal sinus outflow tract (FSOT) including the frontal infundibulum, ostium and recess respectively in the direction of the drained secretions from the sinus towards the …

Obliteration of the frontal sinus, with complete mucosal removal, plugging of the frontonasal outflow tract, and fat grafting of the entire sinus cavity, is an option in some cases.

The two theories of embryological origin are that the FS develops as a result of direct expansion of the infundibulum and frontonasal recess, or as an ascending epithelial migration of the anterior ethmoid cells that infiltrate the frontal bone between its 2 walls during the 16 th week. The FS begins as an insignificant pneumatization in the ...

2015年1月14日 · The relevance of these injuries in the context of frontal sinus trauma is their relationship to nasofrontal outflow tract obstruction as well as the position of the cribriform plate and potential for intracranial violation.

Meticulous anatomical knowledge is mandatory to approach endoscopically the frontal sinus area safely and manage its diseases successfully. The aim of this study was to identify the various drainage patterns of the frontal sinus.

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path...
