Operation Definition
Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection procedures remove an entire ear, nose, or sinus structure without replacing it, most often to treat cancer, extensive chronic infection, or irreversible structural damage. A total mastoidectomy, which clears out diseased mastoid air cells down to the bone in cases of severe chronic otitis media or cholesteatoma, is a common example, as is total or subtotal removal of a nasal or sinus structure for tumor control. Total auriculectomy, removing the entire external ear, may be performed for skin cancer that has invaded the ear's cartilage framework.
Because resection removes the whole body part rather than just a portion, it's a more definitive and often more disfiguring intervention than partial excision, and it's usually reserved for situations where conservative treatment or partial removal wouldn't adequately control disease. Reconstruction, if performed, happens as a separate step - sometimes in the same operative session, sometimes staged for later.
Anatomy & Axis Detail
Frontal Sinus, Right
The right frontal sinus lies within the frontal bone above the orbit and adjacent to the anterior cranial fossa, draining through the frontonasal duct into the middle meatus. Resection removes the entire sinus, an uncommon but significant procedure reserved for frontal sinus osteoma, mucocele with bony erosion, malignancy, or severe post-traumatic disease, and may involve an open osteoplastic flap with obliteration or an endoscopic Draf III approach. Because the posterior sinus wall borders the dura and frontal lobe, resection carries risk of cerebrospinal fluid leak and intracranial complication, and the operative record should specify the technique and any obliteration material used. This distinguishes true resection from simple trephination or endoscopic drainage of the sinus.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Coding & Documentation
Resection applies only when documentation confirms the entire named body part was removed, not a portion of it; removing part of a turbinate or part of the septum is Excision, not Resection, so coders need to read the operative note carefully for words like 'total,' 'complete,' or a clear statement that the whole structure was taken. Pathology reports describing the specimen can help confirm the extent of removal when the operative note is ambiguous.
The most frequent error is applying Resection to procedures that actually removed only a portion of a body part, inflating the code to a higher-acuity procedure than what was performed. Coders should also be alert to mastoidectomy terminology, since 'cortical' or 'simple' mastoidectomy is usually a partial procedure (Excision) while 'radical' or 'total' mastoidectomy meets the threshold for Resection.
