Case ReportsBuccal-masseteric mycotic abscess as a consequence of dental procedures.
Trismus may represent an external sign of masticatory or lateral pharyngeal abscess that in rare cases is the consequence of pathogen action by micro-organisms introduced in deep tissues after inferior alveolar block. The case presented shows a buccal-masseteric mycotic abscess following restorative procedure involving inferior alveolar anesthesia on the same side. A 49-year-old woman was referred to the Dental Clinic (University of Trieste) complaining of a progressive inability to open her mouth since one week associated to a hemifacial edema in the right parotid region. ⋯ Introduction of micro-organisms during anesthetic alveolar block is a documented source of infection and may occur after dental procedure involving inferior alveolar anesthesia. Complete medical history, cultural exam with sensitivity test to antibiotics and RM or computed tomography (CT) images, are necessary to perform an adequate treatment plan and to administer a correct therapy. Presence of trismus, accompanied by pain or facial edema after dental procedure or during dental or perioral infections has to be carefully considered by clinician to diagnose as soon as possible a deep spaces infection and to avoid serious or life-threatening complications.

A median and ulnar nerve block was administered for endoscopic carpal tunnel release. Three (14.2%) of 21 patients required further anesthesia with local anesthetic agents and sedation. No solution ran back to the surgical site. This technique is rapid and reliable, and it seems to be suitable for outpatient surgery.
