Abstract

Objectives: A clear knowledge of the location of the maxillo-facial foramina is essential for clinicians while performing endoscopic surgeries and regional nerve blocks. In the present study, a detailed analysis of the supraorbital foramen (SOF) and supraorbital notch (SON) of South Indian skulls is reported and the data are compared with those from other races and regions.Methods: Anatomical variation of SOF/SON was studied in 83 adult human skulls bilaterally, using “travelling Vernier’smicroscope”. The skulls belonged to the cadavers of South Indian origin. The parameters used were distanced between the SON/SOF and the nasal midline; distance between the SON/SOF and the frontozygomatic suture (FZS); shape and height of the SOF; transverse diameter of the SON; the presence of accessoryforamina (ACF) and their number; as well as the location and distance from the main SON/SOF.Results: SON was more frequently found than the SOF. Themean distance of SON/SOF to the nasal midline was 22.24 mmon the right side and 22.2 mm on the left side. The mean distanceof SON/SOF to the frontozygomatic suture was 29.34 mm on theright side and 28.7 mm on the left side. While the mean height ofSOF was 3.5 mm on the right side and 3.04 mm on the left side.Also, the mean transverse diameter of SON was 5.17 mm on theright side and 5.58 mm on the left side. The accessory supraorbitalforamina were observed in 66.25�0of cases.Conclusion: There is a difference in the position and dimensions of SOF /SON between different races and people of different regions. Anatomical knowledge of SON /SOF is important in facilitating local anesthetic, forehead lifting, blepharoplasty and other craniofacial surgical procedures.

4. Separate Belly and Tendon of Flexor Digitorum Superficialis to the Fifth Digit.

Abstract

Variation in the origin of long flexor tendons in the anterior compartment of forearm is common. During routine cadaveric dissection at Melaka Manipal Medical College (Manipal Campus), we observed a separate muscle belly and tendon of flexor digitorum superficialis (FDS) to the fifth digit in the right upper limb of a 60 year-old male cadaver. The anomalous muscle belly originated from the common flexor tendon from the medial epicondyle of the humerus and continued as a thin tendon at the middle of the forearm to get inserted into the middle phalanx of the fifth digit. This can be considered as a case of split flexor digitorum superficialis. Such muscle variations and knowledge of their frequency, appearance, and location can be helpful for surgeons.
