Middle turbinate stabilization technique in endoscopic sinus surgery.

BACKGROUND: Lateralization of the middle turbinate with scarring and obstruction of the middle meatus after endoscopic ethmoidectomy has accounted for a high percentage of postoperative complications. OBJECTIVE: To evaluate a suture stabilization technique of the middle turbinates in an attempt to solve this problem and preserve the middle turbinate. DESIGN: Retrospective chart review of 31 consecutive patients undergoing endoscopic sinus surgery with suture stabilization of the middle turbinate. RESULTS: With the technique of suture stabilization of the middle turbinate in 60 operated-on sides of 31 patients, 59 sides showed the middle meatus to be patent without synechia or maxillary sinus ostium obstruction postoperatively. CONCLUSION: The complication of lateralization of the middle turbinate with scarring and obstruction of the middle meatus after endoscopic ethmoidectomy can be prevented with suture stabilization of the middle turbinate, and the middle turbinate can be preserved.

CT recognition of lateral lumbar disk herniation.

Although computed tomography (CT) has been shown to be useful in diagnosing posterolateral and central lumbar disk herniations, its effectiveness in demonstrating lateral herniated disks has not been emphasized. The myelographic recognition of those herniations may be difficult because root sheaths or dural sacs may not be deformed. A total of 274 CT scans interpreted as showing lumbar disk herniation was reviewed. Fourteen (5%) showed a lateral disk herniation. The CT features of a lateral herniated disk included: (1) focal protrusion of the disk margin within or lateral to the intervertebral foramen; (2) displacement of epidural fat within the intervertebral foramen; (3) absence of dural sac deformity; and (4) soft-tissue mass within or lateral to the intervertebral foramen. Because it can image the disk margin and free disk fragments irrespective of dural sac or root sheath deformity, CT may be more effective than myelography for demonstrating the presence and extent of lateral disk herniation.

Differential diagnosis of intrasellar tumors by computed tomography.

The specificity of the computed tomography (CT) diagnosis of intrasellar adenoma has not been studied. We compared the CT findings in intrasellar meningiomas, craniopharyngiomas, aneurysms, and metastases with those of pituitary adenomas. Calcification was a features of intrasellar meningiomas, aneurysms, and craniopharyngioma,s but not a typical feature of adenomas. Low-density regions representing necrosis or cyst were found in most types of intrasellar tumors. Eccentricity, hyperostosis, and bone destruction were useful signs of aneurysm, meningioma, and metastasis, respectively. Since adenoma cannot always be distinguished from another intrasellar mass, angiography to demonstrate tumor angioarchitecture may be needed to characterize some neoplasms or to confirm an intrasellar aneurysm.

Supraglottic laryngectomy.

This paper describes the experience with subtotal supraglottic laryngectomy for laryngeal carcinoma at the Department of Otolaryngology of the Tulane University School of Medicine. Of 36 patients, 32 (89%) had local control of diseases at one year. Of 27 patients followed up for at least three years, 22 (81%) are free of disease. Postoperative aspiration was the most frequent complication, but was a serious problem in only one patient. Because of the significant functional advantage of partial laryngectomy, the high rate of disease control, and an acceptable complication rate, we believe supraglottic laryngectomy is the procedure of choice for laryngeal carcinoma in selected patients.
