xylocaine test and computed tomography of both styloid processes. All cases were divided into group-A and group-B and were managed conservatively, and by intraoral surgical approach. Group-A had 17 cases with length of styloid process <25 mm, and group-B had 13 cases with length of styloid process >25 mm. All cases were subjected to tonsillectomy and histopathological examination of the tonsils. In all cases the results and findings were noted and analyzed. Results: In present study of 30 cases, the mean age was 42 years. 27 cases were female while 3 were male. 20 cases had unilateral and 10 cases had bilateral symptoms. 26 cases had chronic fibroid tonsillitis and 4 cases had normal tonsils. 13 cases of group-B underwent styloidectomy. In 15 cases of group-A, the styloid process was not palpable and only tonsillectomy was done. In remaining 2 cases out fracture of styloid was carried out additionally. 28 patients became asymptomatic, 2 were lost to the follow up. There were no any serious complications noted during the management in all cases. Conclusion: Surgical management with intra oral approach is the successful treatment in cases of stylalgia. In our study the sizable percentage (86.66%) of fibrous tonsils as an etiological factor of stylalgia in absence of elongated styloid process indicates the need of concomitant tonsillectomy (by intra oral approach only) during the management.

Thottiyil, M. Mayilswami Amrita School of Medicine, Amrita Vishwa Vidyapeetham, Kochi, Kerala, India Aims and objectives: The term ‘corona mortis’ (CMOR) meaning crown of death refers to an anastomosis between the obturator and the external iliac or inferior epigastric arteries or veins. Located behind the superior pubic ramus, the name testifies to its importance, as considerable hemorrhage can occur when cut accidently during pelvic or groin surgeries or avulsed in fractures of the superior pubic ramus. The aim was to study, by detailed anatomical dissection, the prevalence and the morphological possibilities of the vascular connections termed ‘corona mortis’. Material and methods: Pelves of 16 adult cadavers were dissected to find out the prevalence of CMOR. In addition, 18 hemipelvises randomly available in the department of anatomy were also studied. The vascular composition of the CMOR was classified as pure arterial, pure venous or both together. Results were documented with digital photography. Results: CMOR was present in 23/32 (71.87%) hemipelvises of the 16 cadavers dissected. In 10/32 (31.25%) hemipelvises there were both arterial and venous CMOR. In 3 cadavers, their presence was bilateral. The venous CMOR was present in 10/32 (31.25%) and arterial CMOR in 3/32 (9.37%) cases. Among the random pelvic halves studied, the prevalence of arterial CMOR was 4/18 (22.2%) and venous CMOR 14/18 (77.77%) respectively. Conclusion: The prevalence of both artery and vein or vein alone on the superior pubic ramus is equal. The arterial CMOR is less common. CMOR has widespread clinical implications being closely related to superior pubic ramus, the acetabulum and the femoral
S33
ring. The findings and their clinical implications are discussed in this paper. Conflicts of interest The authors have none to declare. http://dx.doi.org/10.1016/j.jasi.2016.08.110
103 Morphology of extensor tendons of medial four fingers in adults and foetuses: A cadaveric study Biju UrumesePalatty ∗ , R. Nath, K.Y. Manjunath Amirta Institute of Medical Sciences, Amrita Viswa Vidya Peetham, Kochi 41, Kerala, India Aims and objectives: Hand is the most frequently used part of our body, rendering it vulnerable to injury. It is mandatory to enhance the existing anatomical knowledge of the extensor tendons of the hand and their common variations whenever reconstructive surgery is planned in this region. Material and methods: In the present study, data was collected by dissection of fifty hands of formalin fixed adult cadavers and stillborn full term fetuses. All extensor tendons to the fingers were identified cleaned and the number of the tendons strands and splits were recorded. Results: Extensor indicis tendons were absent in 2 (4%) hands. Extensor digitorum (ED) to the index finger was absent in one (2%) hand. The ED to middle finger in one case had multiple tendons (2%). In the case of ED to ring finger a single tendon was found in 22 (44%) cases and multiple tendons were recorded in 6 (12%) hands. ED tendons to little finger were absent in 29 (58%) hands. Extensor digiti minimi tendons was absent in one (2%) hand. Conclusion: Anatomical knowledge of extensor tendons and its anomalies is helpful in identifying and planning tendon transfer or graft surgeries. Presence of multiple tendons may be beneficial in tendon transfer operations. Conflicts of interest The authors have none to declare. http://dx.doi.org/10.1016/j.jasi.2016.08.111
104 Variation in popliteal vein Geetanjali UttamraoYadgire ∗ , S.S. Rawlani, A.M. Chauhan, D.R. Gudadhe Dr PDMMC, Amravati, India Aims and objectives: Popliteal vein is the main vein of lower limb, generally accompanied by the popliteal artery in the popliteal fossa. It ascends to continue as the femoral vein at the hiatus in the adductor magnus muscle. It is of great importance to have the knowledge of the veins of the lower limb and the venous anomalies, to avoid any vascular injury during the surgery on lower limb and for improved assessment and treatment of deep vein thrombosis. Hence, retrospectively to review and evaluate the types of variations and their frequency seen within the popliteal fossa, we carried out a cadaveric study in the department of anatomy of Dr PDMMC, Amravati.
