Sphenoid sinus pyocele after transsphenoidal approach for pituitary adenoma.

Transsphenoidal pituitary adenoma surgery is related to a low morbidity rate. The complications that can occur are classified as intra- and extracranial. The aim of the study is to discuss one group of these complications involving the sphenoid sinus: mucocele and its possible transformation into pyocele.

Clivus chordoma: is it enough to image the primary site?

Chordomas are rare malignant tumors arising from embryonic remnants of the primitive notochord, around which the skull base and vertebral column develop. They are locally aggressive but metastasize rarely. To our knowledge, this is the first reported case of synchronous intraosseous chordomas.

Technique and results of the anterior-to-posterior-to-anterior approach in revision endoscopic sinus surgery.

Objective: To perform the anterior-to-posterior-to-anterior technique in revision endoscopic sinus surgery, and to assess the effects and safety of this technique in treating recurrent chronic sinusitis and nasal polyps.

Methods: One hundred and thirteen patients with recurrent chronic sinusitis and nasal polyps received anterior-to-posterior-to-anterior revision endoscopic sinus surgery. This surgical technique has 5 important steps, including exposing the choana, enlarging the maxillary sinus ostium, opening the sphenoid sinus and posterior ethmoid sinus anteriorly to posteriorly, resecting the ethmoid sinus posteriorly to anteriorly, and opening the frontal sinus posteriorly to anteriorly.

Clinical predictors for germline mutations in head and neck paraganglioma patients: cost reduction strategy in genetic diagnostic process as fall-out.

Multiple genes and their variants that lend susceptibility to many diseases will play a major role in clinical routine. Genetics-based cost reduction strategies in diagnostic processes are important in the setting of multiple susceptibility genes for a single disease. Head and neck paraganglioma (HNP) is caused by germline mutations of at least three succinate dehydrogenase subunit genes (SDHx).
