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
Sphenoid Sinus, Right
The right sphenoid sinus lies deep in the sphenoid bone at the skull base, flanked by the internal carotid artery and optic nerve within its lateral wall and situated just below the pituitary gland. Resection of the entire sinus is performed for sphenoid sinus malignancy or extensive disease such as mucocele or fungal sinusitis eroding adjacent structures, often via a transnasal endoscopic transsphenoidal approach. Its deep, central location and direct relationship to critical neurovascular structures make this one of the higher-risk sinus procedures, frequently performed jointly with neurosurgery when skull base involvement is present. The note should confirm removal of the sinus itself, as this approach is more commonly used simply to access the pituitary rather than to resect the sinus.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
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.
