“…Other authors provided as a measurement point (e.g. to determine the distance to the ethmoidal foramina) the anterior or posterior lacrimal crest [5,6,11,14]. The average result of the present measurements was 43.02 mm (no statistically significant side to side and gender differences), which is similar to the results obtained by other authors (43.77 mm and 42.0 mm) [1,23].…”

“…The starting point in this study is analogous to the point proposed by Ji et al [12] -it is an external bony point in the intersection between the horizontal line that divides the orbit in two equal parts (upper and lower) and the lateral bony margin. This point is equivalent to the Whitnall's tubercle -approximately 1 cm inferior to the frontozygomatic suture and approximately 4-5 mm behind the lateral orbital rim, where attached are the lateral canthal tendon, the lateral rectus check ligament, lateral horn of the levator aponeurosis, suspensory ligament of the lower lid (Lockwood's ligament), the lacrimal gland fascia and the orbital septum [5,16]. Lee et al [15] used for their measurements such horizontal CT images, in which the length of the lateral rectus muscle was largest.…”

“…The knowledge of the anatomy of orbit and periorbital region is important in order to better understand the lesions of this region and to perform safe and effective surgical treatment of these lesions (2). Good anatomical knowledge facilitates surgical procedures to the orbit and decreases the mortality and morbidity after the surgery.…”

AIM:We aimed to show the effects of neuronavigation and intraoperative imaging systems on the surgical outcomes of orbital tumors. MATERIAL and METHODS:Seventeen patients who underwent surgical treatment for orbital tumors by transcranial and transnasal approaches between 2008 and 2013 were analyzed retrospectively. Twelve of them were male and 5 were female. The mean age was 41.6 years. Neuronavigation systems were used in all cases. Four patients were operated using intraoperative imaging systems. RESULTS:The transcranial approach was used in 9 (53%) patients, endoscopic medial orbital approach in 4 (23.5%), endoscopic inferolateral approach in 1 (6%), cranioorbitozygomatic approach in 1, lateral approach in 1, and the combined (medial endoscopic and lateral) approach in 1 patients. Total resection was achieved in 5 patients, gross total excision in 2, subtotal in 9 and partial in 1 patients. CONCLUSION:Modern technology has made a significant contribution to the treatment of orbital tumors. Although technological equipments facilitate the excision of tumors, the level of resection is mainly determined by the nature of tumor and adhesion to the adjacent neurovascular structures. It should not be forgotten that advanced technology never replaces a good anatomical knowledge and surgical experience, but has a complementary role. BULGULAR: Çalışmada 9 hastaya (%53) transkraniyal yaklaşım, 4 hastaya (%23,5) endoskopik endonazal medial orbital yaklaşım, 1 hastaya (%6) inferolateral endoskopik yaklaşım, 1 hastaya kraniyo-orbitozigomatik yaklaşım, 1 hastaya lateral yaklaşım, 1 hastaya ise kombine (medial endoskopik+lateral) yaklaşım uygulandı. Beş hastada total, 2 hastada gros total, 9 hastada subtotal, 1 hastada ise parsiyel eksizyon yapılabilmiştir. KEywORDS SONUÇ:Modern teknolojinin, orbita tümörlerinin cerrahi tedavisinde cerraha büyük katkıları vardır. Her ne kadar bu teknolojik olanaklar, bu bölge tümörlerinin eksizyonlarını kolaylaştırsa da, yine de tümörün çıkarılma oranını, tümörün natürü ve çevre nörovasküler yapılara olan yapışıklığının derecesi belirlemektedir. İleri teknolojinin hiç bir zaman iyi bir anatomik bilgi ve deneyimin yerini tutamayacağı, ancak bunların tamamlayıcı konumda olabileceği unutulmamalıdır.

“…[6] Subperiosteal hemorrhage may occur after sudden increase in venous pressure during a variety of activities or by iatrogenic injury to numerous venous collaterals connecting the superior and inferior drainage systems. The proposed mechanism to develop subperiosteal orbital hematoma is bleeding from subgaleal vessels that enlarges and dissects the subgaleal space, extending to the orbit.…”

Periocular hematoma secondary to subperiosteal injury by a short needle

Bleeding and intraorbital hematoma is one of the most common complications of needle block for ophthalmic local anesthesia. We describe an unusual presentation of hematoma that originated in the subperiosteal space and extended to the subconjunctival and periocular area after a peribulbar block for phacoemulsification in a 55-year-old lady. It required an urgent surgical evacuation in order to reduce the intraocular pressure and save the eye. Detailed management to improve the outcome is discussed.
