CPT® Code 31020

The procedure described by CPT® Code 31020 refers to a sinusotomy of the maxillary sinus, specifically an antrotomy performed intranasally. This surgical intervention involves the use of local anesthesia and a vasoconstrictor, which are administered through the nasal passage. The procedure begins with the injection along the lateral nasal wall, positioned below the inferior turbinate, to minimize discomfort and control bleeding during the operation. A trocar is then utilized to puncture the maxillary sinus through the same intranasal route, allowing access to the sinus cavity. Following the initial puncture, the opening is enlarged using through-cutting forceps, facilitating better access for drainage. The primary objective of this procedure is to drain the maxillary sinus, which may be necessary in cases of infection or blockage. During the process, specimens may be collected for culture and sensitivity testing to identify any infectious agents present. Finally, the sinus is irrigated to clear out any remaining debris or fluid, promoting healing and recovery. This procedure is typically indicated for conditions affecting the maxillary sinus, such as chronic sinusitis or other obstructive processes.
