Purpose: This study assesses the relationship of CSA, cranialization and radiographic glenoid loosening following TSA in the long-term follow-up.
Methods: 26 shoulders with TSA were examined radiographically postoperatively and after a mean 12.6 years. Severe cranialization was defined as direct humeral contact with the acromion and/or acetabularization of the acromion.
Results: A CSA ≥35° was associated with severe cranialization. Glenoid loosening was present in 6/24 shoulders (25%). Severe cranialization was associated with glenoid loosening (p = 0.003).
Conclusion: A postoperative CSA ≥ 35° was associated with severe humeral cranialization after TSA in the long-term follow-up. Severe cranialization correlated with glenoid loosening.Level of evidence IV - retrospective cohort study.

Rosai-Dorfman sphenoorbital histiocytosis with intraparenchymal invasion: Do we have to consider this skull base pathology as a malignant disease?
Surg Neurol Int
September 2024
Center for Cranial Base Surgery, Hospital Angeles Pedregal, Mexico City, Mexico.
Article Synopsis
- Rosai-Dorfman disease (RDD) is a rare histiocytosis often presenting with systemic symptoms, but this case highlights its unusual progression to the brain after skull base involvement.
- The presented case involves a 57-year-old male with severe headaches and a tumor mass affecting several areas, culminating in surgical intervention that revealed RDD.
- The study emphasizes the need for timely surgical treatment to prevent local and systemic disease progression, despite RDD typically being regarded as benign.
Delayed Post-traumatic Frontal Mucocele Occurrence: A Case Report.

Department of Neurosurgery, Athens General Hospital "Georgios Gennimatas", Athens, GRC.
Article Synopsis
- Mucoceles are benign cysts that form when the sinus openings get blocked, leading to potential complications like erosion and expansion into surrounding areas.
- The case presented highlights the development of a frontal mucocele after head trauma, stressing the need for prompt diagnosis and treatment.
- Treatment usually involves removing the mucocele and may require procedures to reconstruct the area to ensure good cosmetic results.
Multidisciplinary approach to severe intracranial, intraorbital allergic fungal sinusitis.
Am J Otolaryngol
December 2024
My Michigan Ear, Nose & Throat, Midland, MI, USA.
Article Synopsis
- Allergic fungal sinusitis (AFS) is a serious condition that leads to bone destruction and can affect the orbit and skull base, prompting the need for surgical intervention when medical management fails.
- The study reviewed 30 cases of AFS with both intracranial and intraorbital involvement, revealing that most patients were young, predominantly male, and many were African American with low-income insurance status.
- Post-surgery, patients experienced an average hospital stay of 4.8 days, with most undergoing combined surgical techniques from specialists, while a significant portion also received follow-up allergy care.
How I do it: single-staged emergency neurosurgical management of frontal penetrating craniocerebral injury with depressed skull fracture.
Acta Neurochir (Wien)
January 2024
Neurosurgery department, Sainte-Anne Military Teaching Hospital, 2 Boulevard Sainte-Anne, 83800, Toulon Cedex 9, France.
Context: Penetrating craniocerebral injury associated with depressed skull fracture is an infrequent yet timely neurosurgical emergency. Such injury frequently occurs in the frontal region during traffic accident or stone throw in the civilian setting. As military neurosurgeons, we present our experience in the surgical debridement and reconstruction of this peculiar type of traumatic brain injury.

Background: Frontal sinus injuries are relatively rare among facial bone traumas. Without proper treatment, they can lead to fatal intracranial complications, including meningitis or brain abscesses, as well as aesthetic and functional sequelae. The management of frontal sinus injuries remains controversial, with various treatment methods and outcomes being reported.
