Forty-four cases of developmental salivary gland defects in 43 patients were analysed
radiologically.
The obtained results were as follows,
1. It occurred more frequently in males(86%) than in females(14%). The age
distribution of patients ranged from 20 to 74 years with the average being 52.7 years.
2. All but one were located between the angle o( the mandible and the molar tooth.
Only one patient showed bilateral occurrence.
3. The shape of the deject was ovoid(15 cases), round(10 cases), or half-ovoid(8
cases).
4. Their size ranged from 5¡¿6 §® to 16¡¿30 §® with the average around 9¡¿14 §®.
5. Twenty-eight cases appeared to be surrounded partially(1/3 - 2/3) by a
hyperostotic border. The thickness of the hyperostotic bolder varied ; thick(14 cases),
moderate(11 cases), thin(9 cases), or mixed(6 cases).
6. Thirteen cases were in contact with the superior border of the mandibular inferior
cortex, 11 cases partially eroded the cortical plate, and 7 cases showed discontinuity of
the mandibular inferior cortex.
7. Twenty-three cases were located below the mandibular canal, 13 cases overlapped
the mandibular canal, and 2 cases showed slight deviation of the mandibular canal.
