Frontal Sinuses

Introduction. The primitive malignant melanoma of nasal mucosa and paranasal sinus is a rare tumor of uncertain etiology, with unpredictable biologic behavior and bad prognosis. Unlike skin melanomas, there are no risk factors and the disease is frequently manifested in older patients, whose clinical otorhinolaryngology complaints are normally non-specific and ranges from nasal obstruction to rhinorrhea and epistaxis. Unfortunately, this disease is diagnosed basically in advanced stages which makes the surgery difficult. Objective. To report a case of primitive malignant melanoma of nasal mucosa, ethmoid and frontal sinuses, that was diagnosed in 2015. It was performed a subtotal resection in another hospital in 24.08.2015, with a large local reccurence. Report. Our patient was a 78-year-old woman with bilateral nasal obstruction, light epistaxis and unilateral rhinorrhea. The ENT, CT and  MRI exams showed a tumour with important, invasion of the nasal cavity structures (billateral nasal bones, left frontal process of the maxilla, the superior midpoint of the nasal septum, bilateral middle and superior turbinates, left ethmoid and bilateral frontal sinuses). The patient was submited for surgery: total macroscopic resection in the combined endoscopic approach; transnasal and modified lateral rhinotomy with titaniul plates reconstruction of the external nose architecture. Conclusions. Malignant melanomas of nasal mucosa are, in general, diagnosed in advanced stages. Their histological characteristics in the mucosa makes difficult the surgical treatment, which is one of the most efficient options, because they are resistant to chemo and radiotherapy. The early diagnosis and a good surgical treatment plan are the best option for this tumor nowadays.

Abstract We present our experience with the surgical treatment of olfactory groove meningiomas using a pterional approach. This approach provides the advantages of previous techniques, such as preserving the frontal brain and superior sagittal sinus, early devascularization of the tumor, and late dissection of tumor borders. Moreover, it also compensates for the shortcomings of other techniques, e.g., compression of frontal bridging veins, late dissection of dorsal tumor aspects involving vessels and optic nerves as well as facultative infection and cerebrospinal fluid fistula-related complications caused by opening of frontal sinuses. To date, 11 patients were treated in this way. As we encountered no surgical complications in our series we are encouraged to present our procedure.

We have developed a technique to measure gas non-intrusive in scattering media, such as human tissue. The technique was first demonstrated for test samples in 2001 by our group and utilizes diode laser absorption spectroscopy to monitor molecular oxygen and water vapor. The focus of medical application has been on sinuses, both maxillary and frontal sinuses and the potential of the technique has been shown on volunteers. A spin-off company named GasPorOx AB has been formed with the aim to develop a product used to improve the diagnosis of the sinus infections. A portable fiber-guided system has been developed and is used in an ongoing initial clinical trial in collaboration with the Ear, Nose and Throat Clinic, the Oncology and Diagnostic radiology clinics at the Lund University Hospital.
