OBJECTIVE To clarify the spatial orientation relevant to the endoscopic sinus surgery (ESS) for the frontal sinus. METHODS Various dimensions of structures around the frontal recess were measured on 256 CT images of 128 Japanese patients using the multiplanar reconstruction technique. Measurements done in this study were: the distance from the nostril to the narrowest point of the frontal rec...

A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

UNLABELLED Frontal pneumosinus dilatans is a rare entity that is documented only by a few reports. It is an abnormal expansion of the aerated frontal sinus, with sinus walls of normal thickness. The expansion of the bone may be generalized or focal. It is not only an aesthetic problem but may also have functional consequences. We herein present the case of a 23-year-old woman who had been refer...

INTRODUCTION Piezosurgery, a method of bone cutting utilizing ultrasound vibrations, widely used in oral and maxillofacial surgery, is being used in a growing number of new clinical applications. Its main advantages are preservation of soft tissues, precise bone cutting, and the possibility of use in narrow spaces. Over the past 5 years, several authors have presented their experience with the ...

Inappropriate treatment of fractures of the frontal sinus can lead to serious complications. These fractures are often associated with soft tissue injuries and loss of bony structures. This case report shows the use of methyl methacrylate frontal prosthesis to treat a sequel of frontal sinus fracture; surgical options are discusses and one-year follow-up is present to show stability and good co...

A frontal mucocele is an epithelium-lined, mucuscontaining cyst filling in the frontal sinus. It is capable of expansion to erode the surrounding structures, which may result in severe complications such as orbital infection or intracranial lesions. The clinical presentation of frontal mucoceles includes frontal headache, swelling of the upper eyelid, and ophthalmic symptoms, such as proptosis ...

Abstract Background Frontal sinus carcinoma is commonly seen as an extension of the ethmoid sinus, overlying skin, or lacrimal gland. The existence this disease has been unclear. We aimed to describe occurrence primary frontal carcinoma. Methods conducted a systematic literature review and retrospective medical records at our institution in past 10 years. Results Sixty-four articles were includ...

Ossifying fibroma is a rare benign tumor of the nasal cavity and the paranasal sinus, and is easily misdiagnosed. In the present study, we report the clinical data in the case of a 46-year-old female patient, treated due to 5-day forehead swelling accompanied by dizziness. CT examination revealed dilation of the right frontal sinus, bone wall integration, dense masses in the cavity, multiple pu...

A mucocele of paranasal sinuses is a collection of mucus within an epithelial lined sinus whose outflow tract is permanently obstructed. The most common site for a mucocele is the frontal sinus; it is less common in the other sinuses. Frontal mucoceles present in different ways depending upon their size and duration, with symptoms often gradual and insidious. Symptoms are mainly ophthalmic and ...
