BACKGROUND. Polyps, cysts and mucocele are the commonest sinonasal tumors present unilaterally, as well as invasive tumors, such as inverted papillomas and squamous cell carcinomas. On the contrary, Schwannomas are rare lesions found in this area.

MATERIAL AND METHODS. We present a case of a 48-year-old female who presented with a 2-year progressive history of left nasal obstruction, cranio-facial fullness sensation and pain, with intermittent epistaxis. The CT scan of the nose and paranasal sinuses showed complete opacification of the entire left nasal cavity and maxillary sinus, causing a deviated nasal septum to the right side.

RESULTS. The tumor was completely excised endoscopically without any complication. Histopathology was consistent with that of a schwannoma.

CONCLUSION. The diagnosis of sinonasal Schwannomas remains challenging, as it is a rare tumor and sometimes its clinical behaviour and imaging may be misleading. The treatment of choice for paranasal sinus schwannoma is complete excision of the tumor with good prognosis.


ENT surgeons frequently encounter a variety of neoplastic, non-neoplastic and inflammatory masses involving the nasal cavity, the paranasal sinuses or the nasopharynx. Among these, the angiomatous polyp or angiectatic nasal polyps are rare and account for 4-5% of all inflammatory nasal polyps. They have variable growth patterns and clinical features. In angiomatous nasal polyps, there is a prominent component of dilated capillary-type blood vessels. We present a review of the literature regarding the most important features of this pathology and an unusual case of a large angiomatous polyp arising from the maxillary sinus.

The study was performed on 38 divers of the navy. The research consisted in an analysis of RTG images of paranasal sinuses performed during control examinations. The authors compared sinus aeration in particular tests and calculated planimetric indices. It was concluded that an exposure to pressure fluctuations caused changes in the image and aeration of maxillary sinuses, which however did not have an effect on the diving capabilities of the tested group. Moreover, it was revealed that in a certain group of the subjects an exposure to hyperbaric conditions did not manifest any detectable lesions in maxillary sinuses.


The barofunction of paranasal sinuses is of great significance in terms of diving safety and comfort. The paper aimed at determining the changes in the aeration of maxillary sinuses as a result of diving activities on the basis of a radiological image. Inter alia, it was observed that individuals who frequently practise diving show persistent changes in the radiological image of sinuses, however, usually they do not influence the diving capacity.
