Background And Purpose: The direct transnasal approach is a less invasive approach to the sella turcica and represents an alternative to the sublabial transsphenoidal approach with minor oro-nasal complications. In this study, we describe this approach with emphasis on post-operative course.
Methods: We studied retrospectively 60 patients operated on consecutively by a transnasal approach between January 1996 and December 2000.
Results: There were 47 macroadenomas, 9 microadenomas and 4 non-adenomatous pathologies. Despite its narrowness, the transnasal approach was possible in all cases and allowed tumor removal as satisfactory as with the sublabial approach. Eight patients had complications not directly related to the approach: 1 death (meningitis with brain stem ischemia), 3 pituitary fossa hematomas, 4 rhinorrheas and 2 meningitis. Seven patients had complications related to the approach: 2 nasal obstructions, 1 nasal dryness, 2 sinusitises and 2 hyposmias. All these local complications were transitory and disappeared within 3 months.
Conclusions: In our experience, the direct transnasal approach is safe, quick and less invasive than the sublabial approach.

Parkinson's disease (PD) is a prevalent neurodegenerative disorder characterized by pathological changes, including the loss of dopaminergic neurons and abnormal aggregation of α-synuclein (α-syn). Certain cellular and molecular events are involved; however, the origin and significance of these events remain uncertain. The discovery of microRNAs (miRNAs) predicted to play a pivotal role in various regulatory processes has emerged.

Objective: Transcranial electrical stimulation (TES) is an effective technique to modulate brain activity and treat diseases. However, TES is primarily used to stimulate superficial brain regions and is unable to reach deeper targets. The spread of injected currents in the head is affected by volume conduction and the additional spreading of currents as they move through head layers with different conductivities, as is discussed in [1].

Background: The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.
Observations: The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively.

Objectives: Surgery is the only treatment for congenital choanal atresia (CCA). It is crucial to avoid postoperative restenosis or re-occlusion of the neo-choana. This study investigated the efficacy of a navigation-assisted endoscopic endonasal U-flap technique and a bioabsorbable steroid-eluting stent for CCA repair.

Background And Objectives: Congenital choanal atresia is a rare condition that occurs in approximately 1 in 7,000 to 8,000 live births and involves the obstruction of the posterior nasal airway. It may present as either unilateral or bilateral, with bilateral cases being more severe due to the risk of immediate neonatal respiratory distress. Bilateral congenital choanal atresia (BCCA) necessitates prompt medical intervention to prevent cyanosis and significant breathing difficulties.
