BACKGROUND The present study is aimed to ascertain the position of transverse axis of temporomandibular joint in living subjects by devising a new method, which remains hypothetical till date with a hope that it can help the biomechanical engineers and Orthodontic surgeons to go for manufacturing suitable prosthesis for patients with fractured jaw. MATERIALS AND METHODS The present study was conducted at MMIMSR, Mullana-Ambala, Haryana on 1200 subjects (600 males and 600 females) belonging to three states (Haryana, Himachal Pradesh and Odisha) of India. The superimposition method adapted in which two triangles have been constructed (i.e. triangle of closed mouth and triangle of opened mouth) by selecting three bony landmarks (Na-Nasion, Cy-Condylion and Go-Gonion) and taking three measurements (Na-Cy, Na-Go and Cy-Go). RESULTS The study revealed that in average the transverse axis is positioned 11 mm above Midramus Point (MRP) in 94.08% of total population, at MRP in 0.92% and below MRP in 5% cases. Similarity in the findings was seen between Haryanvi and Himachali population as well as between Himachali and Odisha males. It is above MRP in 95.58%, at MRP in 0.67% and below MRP in 3.75% of all males; above MRP in 92.58%, at MRP in 1.17% and below MRP in 6.25% of females of three states. CONCLUSION Bilateral symmetry is maintained in the position of transverse axis with minimum difference in females of three states compared to males. Bilateral symmetry is well maintained in Himachali females.

Potter's sequence is more appropriate terminology than potter facies, since not every individual with this syndrome has exactly the same set of symptoms and signs but they share a common chain of events triggered by different causes, leading to the same endpoint of reduced or absent amniotic fluid. It has a characteristic facial appearance associated with other abnormalities as Ophthalmic(Cataract), Cardiovascular (Ventricular septal defect. Fallot's tetralogy, Patent ductus arteriosus), and musculoskeletal (Clubbed feet, Sacral agenesis) . Here we are presenting two cases of potter sequence due to polycystic kidney disease ( type-i ) in association with other congenital anomalies ( absence of left diaphragm ,pericardial effusion, pulmonary hypoplasia ) which is rare and incompatible to life .
