ABSTRACT
Leiomyosarcomas (LMSs) of the sinonasal tracts are rarely reported. We present a case of an LMS of the left inferior nasal concha, and discuss the management options with review of the literature. A 72-year-old female patient presented with epistaxis. Clinical examination and medical imaging showed a tumour arising from the left inferior nasal concha. An endoscopic resection was performed. Anatomopathological and immunohistochemical analyses revealed the tumour to be a grade 3 LMS with uncertain posterior margins. The patient was a Jehovah's Witness and refused more radical surgical resection due to religious beliefs; therefore, adjuvant conformal radiotherapy (60 Gy) was performed. LMS of the nasal cavity is a rare and locally aggressive tumour with a high tendency of recurrence, requiring radical surgical resection and long-term follow-up. The prognosis of a nasal cavity LMS is better than that of an LMS located in the paranasal sinuses.

Many studies have established high-frequency audiometry norms. Unfortunately the majority presents different averages for each decade, sex and frequency together with standard deviations. In order to solve these problems we established our norms on a widespread audiometer for each sex based on a strictly normal hearing sample. We calculated the linear regression between age and hearing loss for each frequency. We propose a set of equations to predict the "normal" threshold of a subject in function of age and sex.

Although osteomas of the paranasal sinuses are slowly growing bony benign neoplasms, they can cause very important orbital or neurological complications. A 58 year old man's osteoma with sinusitis, abscess and proptosis is reported. A review of the literature is presented and the importance of CT scanner, to appraise the enlargement of the tumor and so to select the best surgical approach, is defined.
