Abstract
Background and Objectives The soft palate has morphological variations in lateral
cephalometric images. Several studies are available on the analysis of the dimensions of the
soft palate, but few have investigated the morphology of the soft palate. The aim of this study
is to investigate the relationship between morphological variations of the soft palate and
types of malocclusion in Ahvaz, southwest of Iran.
Subjects and Methods In this descriptive-analytical study, the lateral cephalometric images of
162 patients with abnormal skeletal pattern available in the archive of the Radiology
Department of Jundishapur School of Dentistry in Ahvaz were used. The radiographs were
divided into 6 groups (leaf shape, rat tail shape, butt like, straight line, distorted soft palate,
and crook shape) under the supervision of a radiologist. The data were analyzed to determine
the relationship between soft palate morphology and skeletal pattern .
Results The results showed that 51.2% of the patients’ skeletal pattern were class two, 37%
were class one, and 11.8% were class three . The most prevalent soft palate morphology
observed in this study was the "rat tail" shape, accounting for 61.7% of all participants. This
morphology was consistently the most common across all investigated skeletal
classifications. The "leaf" shape followed in prevalence, representing 18.5% of the sample.
The least frequent morphology, identified in only 2.5% of participants, was the "S-shaped"
type. This pattern of prevalence held true within each individual skeletal pattern as well.
Conclusion Rat tail shape of soft palate was by far the most common morphology while
distorted soft palate or S-shaped soft palate was the rarest form of soft palate in patients.
There is no relationship between the skeletal pattern of the jaw and the morphology of the
soft palate in the studied population .
