Laboratory Studies

No specific laboratory studies, imaging, or diagnostic procedures are required in the evaluation of microstomia. However, any systemic abnormalities that result from the underlying cause of the microstomia may affect the patient's ability to heal from the inciting event or to undergo anesthesia and surgery; thus, such systemic abnormalities should be sought. For example, patients with electrical burns should undergo an ECG because myocardial injuries, conduction abnormalities, or both are possible and must be promptly diagnosed. Computerized tomography or radiography of the chest may be useful in patients with scleroderma for determining the presence of pulmonary fibrosis. Endoscopic evaluation of the airway should be considered in patients with microstomia due to epidermolysis bullosa.

ECG is appropriate in cases of electrical burns because myocardial injuries, conduction abnormalities, or both are possible and must be promptly diagnosed.
