Fungal rhinosinusitis is an important pathological entity, a highly controversial topic in the medical world today, by the various research directions it offers. In order to be able to predict a patient’s prognosis and his response to treatment, first we must have a classification of fungal rhinosinusitis. The authors considered it is important to make a distinction between invasive and noninvasive forms of fungal rhinosinusitis. The most important step in the management of fungal rhinosinusitis is to have a correct diagnosis, based on strong criteria, which will lead to a better prognosis of this disease. Because of its invasiveness potential, especially in patients at risk, it is essential to have a correct and fast diagnosis in case of fungal rhinosinusitis, in order to begin the treatment as fast as possible, for a favourable prognosis. The only way to establish diagnosis in a reliable way is to make a detailed clinical examination and to take biopsy samples.

A cerebrospinal fluid (CSF) leak occurs when there appears a fistula between the dura and the skull base and it is usually characterized by discharge of cerebrospinal fluid from the nose. Cerebrospinal fluid leaks may have many etiologies, the most common being trauma. The most common site of dural lesion is the cribriform plate of the ethmoid. Diagnosis can be achieved by a multitude of techniques, high-resolution computed tomography being the modality of choice and it may be completed with magnetic resonance imaging or cisternography. Treatment may be either conservative, either surgical, related to the cause, the site and the duration of CSF leak. Conservative treatment usually includes strict bed rest, elevated bed head and no straining, nose blowing or stretching, with resolution of the majority of traumatic CSF leaks in seven days. Surgical treatment consists of a variety of approaches (intracranial/extracranial, open/endoscopic). The future trend is represented by minimally invasive endoscopic approaches, with a success rate of almost 90%; however, open transcranial or extracranial interventions still have indications in the surgical management. CSF leaks must be correctly diagnosed and treated, because the risk of intracranial complications increases 10-fold when the leakage persists.

Thyroglossal duct cyst (TDC) has an increasing incidence. We present a series of three cases that benefited from the use of ultrasonography performed first hand by the ENT specialist. All cases underwent Sistrunk procedure and the diagnosis was confirmed by pathology results: one uncomplicated TDC, a thyroglossal duct carcinoma, and an infected TDC with the risk of becoming a diffuse cervical suppuration. Ultrasonography performed first hand by the ENT specialist enables a quick and thorough planning of the surgical procedure and management of the case.

The nasal swell body (NSB) is considered to be an enlarged region of the nasal septum, which is located superiorly to the inferior nasal turbinate and anteriorly to the middle nasal turbinate, with a potential effect upon the airflow nasal valve. The histological studies of the NSB demonstrated that it is a glandular formation, not a venous structure, and it is formed by septal cartilage and bone, as well as a thick mucosa. Recent studies emphasized the functional role of the nasal swell body and it is thought to interfere with the nasal airflow and air humidification, due to its proximity to the internal nasal valve and its histological characteristics (venous sinusoids and seromucinous glands). The nasal swell body is strongly related to the presence of rhinosinusal chronic inflammations (allergic rhinitis and chronic rhinosinusitis) and the septal deviation. In case of the presence of the nasal swell body, surgical treatment is not commonly done, due to the absence of a consensus between the ENT practitioners. Most of them consider surgery as being too aggressive because of the presence of seromucinous glands, with slight impact upon the nasal obstruction. Most probably, the lack of consensus is determined by inconsistent anatomical and histological study results.
