OBJECTIVES The aim of this study is to investigate the relationship between the thickness of the roof of the glenoid fossa in the temporomandibular joint (TMJ) and the existence and types of condylar bone change. MATERIALS AND METHODS Helical CT was used to measure the thickness of the roof of the glenoid fossa at its thinnest part in 37 orthodontic patients with temporomandibular disorders. ...

BACKGROUND The skeletal morphology of the temporo-mandibular joint (TMJ) is constantly remodeled. AIMS AND OBJECTIVES A comparative study was undertaken to determine and characterize the differences in the skeletal morphology of TMJ of children and adults. MATERIALS AND METHODS The study was conducted on 30 children cadavers and 30 adult volunteers. Parameters that could reflect TMJ skeleta...

BACKGROUND Sphenoorbital meningiomas are surgically challenging because of their nature to extend to adjacent structures. Here, we describe a case of recurrent sphenoorbital meningioma extending into the sphenoid sinus, pterygopalatine fossa, and infratemporal fossa, which was resected using combined simultaneous transcranial and endoscopic endonasal approaches. CASE DESCRIPTION A 62-year-old...

Objectives: This study was undertaken to evaluate glenoid fossa changes in response to twin block appliance therapy and to correlate the changes in glenoid fossa with changes in craniofacial morphology. Materials and methods: The present study was conducted on pre and post-treatment cephalograms of 30 (15 males and 15 females) myofunctionally treated, Angle’s Class II div. 1 patients with the m...

Posterior fossa surgery is demanding and hides a significant number of obstacles starting from the approach to the wound closure. The risk of cerebrospinal fluid (CSF) leakage in posterior fossa surgery given in the literature is around 8%. The present study aims to introduce a sandwich closure of the dura in posterior fossa surgery, which reduces significantly the number of CSF leaks (3.8%) in...

OBJECTIVE The aim of this study was to determine the posterior cranial fossa volume, cerebellar volume, and herniated tonsillar volume in patients with chiari type I malformation and control subjects using stereological methods. MATERIAL AND METHODS These volumes were estimated retrospectively using the Cavalieri principle as a point-counting technique. We used magnetic resonance images taken...

OBJECTIVES The central location and complex neurovascular structures of the posterior cranial fossa make tumor resection in this region challenging. The traditional surgical approach is a suboccipital craniotomy using a microscope for visualization. This approach necessitates a large surgical window and cerebellar retraction, which can result in patient morbidity. With the advances in endoscopi...

Dandy-Walker complex (DWC) is a malformative association of the central nervous system. DWC includes four different types: Dandy-Walker malformation (vermis agenesis or hypoplasia, cystic dilatation of the fourth ventricle and a large posterior fossa); Dandy-Walker variant (vermis hypoplasia, cystic dilatation of the fourth ventricle, normal posterior fossa); mega cysterna magna (large posterio...

Bilobed flaps were first introduced to close small nasal defects. We reconstructed a defect of the popliteal fossa using a random-pattern bilobed flap. We recommend the use of random-pattern bilobed flaps as a reliable technique for covering defects of the popliteal fossa.

OBJECTIVE To develop a novel approach of transseptal puncture guided by intracardiac echocardiography and to assess its efficacy. METHODS Transcatheter intracardiac echocardiography with a 9 MHz rotating transducer was performed to guide transseptal puncture in 12 patients (mean age 43.1 years, range 31-68) who underwent radiofrequency catheter ablation of left sided accessory pathways. Initi...
