Removal of unusual, large high-velocity metallic maxillary sinus foreign bodies by a modified free bone flap technique

Abstract

Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin.Potential complications related to foreign bodies include recurrent sinusitis, rhinolith formation, cutaneous fistula,chemical poisoning, facial neuralgic pain and even malignancies.Two main surgical approaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus techniques. We are reporting two unusual cases of large high-velocity foreign bodies removed by a modified maxillary lateral antrotomy,with free bone flap repositioning and fixation with a titanium miniplate.

Removal of a Fixation Screw That Was Forced Into the Postsuperior Maxillary Sinus Wall

“…Recommended methods of extracting foreign bodies that have migrated include the Caldwell-Luc approach, in which the maxillary sinus is opened up from the canine fossa, as well as a method involving the use of a nasal endoscope. 11,12 In our patient, (1) computed tomography findings suggested that the screw had invaginated into the bone, (2) the transnasal approach was expected to be difficult considering the position of the invagination, and (3) careful surgery was required because the screw was close to the skull base. Taking all these factors into account, we selected a method wherein the canine fossa was drilled open to gain a sufficient surgical field, and we extracted the foreign body.…”

Removal of Maxillary Sinus Metallic Foreign Body Like a Hand Sewing Needle by Magnetic Iron

“…Two main surgical approaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus techniques. 1 The best treatment option to remove displaced implants into the maxillary sinus is the functional endoscopic sinus surgery. The advantage of this surgery—apart from removal of the displaced implant from the maxillary sinus—is the creation of adequate patency from the natural maxillary ostium.…”

“…1 There is a possibility of foreign bodies penetrated into the maxillary sinus due to the special features of the posterior aspect of the maxillary bone. In this area, the bone is poor quality and quantity.…”

Removal of wood fragments from the maxillary sinus: a case report

“…Recurrent infections, neuralgia, chemical poisoning, antrolith formation and cutaneous fistulae may result from the presence of foreign bodies in the maxillary sinus 5 . To avoid complications, the body must be removed either by the classical surgical Caldwell-Luc technique or through the more recent endoscopic procedures used in the diagnostic and treatment of these conditions.…”
