Sinonasal Malignant Melanoma Variant: A Case Report.

Sinonasal malignant melanoma (SMM) is a rare malignant tumour among head and neck cancers predominantly found in adults 60 years and above. The commonly reported symptoms for sinonasal tumour lesions are nasal obstruction and recurrent, painless epistaxis as the symptoms are non-specific and can delay the diagnosis. Moreover, melanoma has a poor prognosis regardless of its location.

Outcomes of microdebrider-assisted versus radiofrequency-assisted inferior turbinate reduction surgery: a systematic review and meta-analysis of interventional randomised studies.

Background: The microdebrider technique was introduced in clinical practice to provide a better outcome in nasal obstruction caused by inferior turbinate hypertrophy. We conducted this systematic review to evaluate the effectiveness of this technique, by comparison with the radiofrequency-assisted modality.

Methodology: PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched to retrieve relevant randomised studies published prior to November 2019.

Accuracy of preoperative fine needle aspiration in diagnosis of malignant parotid tumors.

To determine the diagnostic accuracy of fine needle aspiration (FNA) for detecting malignant parotid tumors. Methods: We conducted a retrospective study of all patients diagnosed with benign or malignant parotid gland tumors in King Abdulaziz University Hospital,  Jeddah, Saudi Arabia, between January 2004 and May 2015. The records of 65 subjects were obtained.
