medial maxillectomy

medial maxillectomy

A radical procedure used to excise benign and low-grade malignancies of the medial aspect of the maxilla, the lateral nasal wall, ethmoid sinuses and lacrimal sac, in which the maxilla is removed with the tumour.
 
Approach
Lateral rhinotomy incision or midfacial degloving. The medial maxillectomy has been replaced by endoscopic sinus surgery where possible, but the lateral rhinotomy approach is still useful given the wide field it provides. It is also of value when combined with a craniofacial approach for aggressive neoplasms of the skull base.

Historically, surgical treatment has involved aggressive open procedures such as medial maxillectomy. (2) But the advent of endoscopic techniques for both meticulous removal of tissue and subsequent direct observation of the nose and sinuses has enabled surgeons to switch to a closed endoscopic procedure to remove inverting papillomas.
The patient underwent a right medial maxillectomy via a Denker extended maxillary anterior antrostomy approach.
They range from the simple to the complex--debridement of the necrotic mucosa; Caldwell-Luc surgery; medial maxillectomy, ethmoidectomy, and sphenoidotomy; and radical maxillectomy with orbital exenteration.
The traditional extemal approach has been a medial maxillectomy via a lateral rhinotomy or midfacial degloving.
The following morning, the patient underwent a lateral rhinotomy, medial maxillectomy, and excision of the lesion.
[5] The primary advantages of the Le Fort approach are that it offers good access to the posterosuperior nasopharynx with minimal bone removal (unlike lateral rhinotomy and medial maxillectomy), and it poses no direct risk to major vessels and cranial nerves as long as the surgeon adheres to its boundaries.

Endoscopic sinus surgery was selected on the basis of the preoperative findings, and left endoscopic medial maxillectomy was performed under general anesthesia.
The surgical approaches that can be used for infrasellar craniopharyngiomas include the lateral rhinotomy approach, Denker's medial maxillectomy approach, the transpalatal approach, and the transsphenoidal approach.
(1) Then, 1 to 2 months following the completion of radiotherapy, surgery is performed, usually involving a craniofacial resection or medial maxillectomy. (1) Exclusion criteria for surgery include invasion of the cavernous sinus, orbital apex, or brain, or extensive disease of the infratemporal fossa.
The two recurrences that occurred were after a combined open lateral rhinotomy and transpalatal approach for stage II tumour (patient ID# 6) and via a Weber-Ferguson medial maxillectomy approach for stage IIIa tumour (patient #13).
