The atypical presentations of skull base osteomyelitis pose a diagnostic challenge. This case highlights that even otitis media is a potentially fatal infection in older patients with diabetes. Early diagnosis and aggressive management of skull base osteomyelitis are of upmost importance and will ensure a more favorable prognosis.
  Crista galli is extremely important in the endoscopic transcribriform approaches and some extradural approaches. Because of its clinical significance, the morphometric properties of crista galli should be well known.  https://www.selleckchem.com/products/tertiapin-q.html  In this study, it was aimed to examine the morphometry and the pneumatization incidence of the crista galli in cone beam computed tomography (CBCT) images.
 
  In this retrospective study, the length and width of the crista galli were measured in CBCT images of 300 healthy individuals. Besides, the presence of crista galli pneumatization was examined.
 
  The length and width of the crista galli were determined to be as 14.03 ± 2.93 mm and 3.73 ± 1.48 mm, respectively. Pneumatized crista galli was detected in 53 out of 300 individuals (17.67%). There was no statistical difference between the presence of pneumatization and both length and width values of the crista galli (P = 0.876 and P = 0.478, respectively). In addition, no relationship was determined between age and the presence of pneumatization (P = 0.167).
 
  In this study, it is seen that the length (range 6.00-23.40 mm) and width (range 1.40-8.00 mm) of crista galli are in a very wide range. Besides, it is seen in the literature that the incidence of crista galli pneumatization is in a very wide range (2.4% to 66.6%). Based on the available data, it will not be possible to determine a specific range of values for crista galli morphometry. Therefore, the authors think that CT imaging is extremely important in preoperative evaluation.

  Isolated intraorbital mucocele without anatomical communication between the sinus and orbital cavity, and all orbital walls are intact is rare. It may lead to many orbital symptoms including proptosis, diplopia, orbital pain. Traditionally, many cases of typical paranasal sinus mucocele are successfully treated with endoscopic marsupialization. Most of the isolated intraorbital mucoceles were treated with complete removal of the mucocele via an external approach. However, there are many disadvantages of the external approach, and a case of isolated intraorbital mucocele in medial orbit treated by endoscopic intranasal marsupialization was reported. Here, the authors report a case of isolated orbital mucocele in inferior orbit treated by endoscopic intranasal marsupialization.

  An ossifying fibroma (OF) is a type of benign fibro-osteoma that rarely involves the sinonasal cavity. Recent developments in endoscopic sinus surgery allow the removal of large benign tumors from the nasal cavity and sinuses. Here, the athors report the case of a 48-year-old female who underwent endoscopic sinus surgery under general anesthesia to completely remove a large OF involving the sphenoid sinus and nasal cavity. No recurrence was noted during the recent 3-year follow-up. Endoscopic resection of OFs is an excellent choice for very experienced surgeons, affording the advantages of direct observation as well as visual enhancement and magnification, thus reducing intra- and post-operative morbidity.

  Tonsillitis is a very common condition. It is usually of viral origin, is self-limiting, is generally treated conservatively in practice. Complications can be divided into non-suppurative and suppurative. According to the literature search, there is no reported case of posterior plica perforation caused by recurrent tonsil infections. The authors aimed to present the first case of posterior plica perforation caused by recurrent tonsillitis in the literature.
