The palatal overlap flap: a modification of the maxillary swing procedure to prevent ascending infection.
The maxillary swing procedure provides an excellent approach to the anterior skull base region and to the clivus. The osteotomy should not be standard; it should vary with the size and position of the central skull base tumor being resected. The main reason for publishing this article is to draw attention to a method of preventing ascending infection from the oral cavity to the intracranial area using the palatal overlap flap. Examples of this approach are provided.
