Soft tissue calcifications in the head and neck region: A CBCT based retrospective study

Abstract

Background: Soft tissue calcifications are most commonly seen in two-dimensional radiographs. Some may be physiological, and some may be pathological and need treatment. CBCT images provide valuable information about anatomic structures and pathologies. These soft tissue calcifications can be seen clearly in CBCT without superimposition and can be diagnosed appropriately. Aim and Objectives: This study aimed to assess the type and prevalence of calcifications found in CBCT volumes obtained for various diagnostic purposes. The objective of the present study was to determine the prevalence of soft tissue and to find their anatomic location, size, and type as well as their relation to age and gender. Materials and Method: Three hundred full-skull CBCT volumes were retrieved retrospectively from the age-group of 9–75 yrs and were evaluated for calcifications. The study sample included CBCT volumes taken for all diagnostic purposes, and those which contained artifacts were excluded. Results: Of 300 CBCT volumes, 133 were females, and 167 were males. Among them, 446 calcifications were encountered in 177 individuals. Their distribution was pineal gland calcification (24.8%), tonsillolith (18%), choroid plexus calcification (24%), pulp stone (12.4%), calcified stylohyoid chain (8%), sialolith (4%), triticeous cartilage calcification (2%), phlebolith (3%), and extracranial carotid artery calcification (1%). Conclusion: Although most of the calcifications are asymptomatic and require no treatment, correct identification of these findings will reduce further diagnostic assessment and provide more appropriate treatment plans. It will also provide the ability to evaluate underlying diseases comprehensively, and practitioners will have life-saving information by early diagnosis.
