Three-wall orbital decompression superiority to 2-wall orbital decompression in thyroid-associated ophthalmopathy.

PURPOSE: We evaluated the results of the 2-wall and 3-wall orbital decompression in patients with Graves' disease. PATIENTS AND METHODS: In this study, we present a consecutive series of 12 patients (18 orbits) who were submitted to orbital decompression by endoscopic transnasal medial wall combined with transantral inferior wall approach and 7 patients (8 orbits) who were submitted to orbital decompression by endoscopic transnasal medial wall, transantral inferior wall combined with transcutaneous lateral wall approach. The degree of exophthalmos was evaluated with the Hertel exophthalmometer preoperatively and postoperatively in the 24th hour, and first, third, and ninth months. RESULTS: At the end of the third month, the exophthalmos decreased by a mean of 4.38 mm (range, 3 to 7 mm) with the 2-wall decompression and 7.75 mm (range, 5 to 12 mm) with the 3-wall decompression. Visual acuity maintained or improved during the follow-up period. Ocular motility disturbance occurred in 1 patient after 2-wall decompression and in 1 patient after 3-wall orbital decompression. Postoperatively, new-onset diplopia was seen in only 1 patient after 2-wall orbital decompression. CONCLUSION: The 3-wall (endoscopic transnasal medial wall, transantral inferior wall combined with transcutaneous lateral wall) approach is as safe as the 2-wall approach. Proptosis reduction is much better with the 3-wall orbital decompression.

Surgical approaches to juvenile nasopharyngeal angiofibroma.

INTRODUCTION: Juvenile nasopharyngeal angiofibromas are highly vascular, non-encapsulated tumours affecting predominantly young males. These lesions are benign histologically but they may become life-threatening with excessive bleeding or intracranial extension. MATERIAL AND METHODS: The surgical approaches to 22 male patients with nasopharyngeal angiofibromas are reviewed. A modification of midfacial degloving performed without rhinoplasty incisions and lateral osteotomies is described. RESULTS: The patients' ages ranged between 9 and 26 years (mean 14.9). Three stage I tumours, 8 stage II tumours, 6 stage III tumours and 5 stage IV tumours were included into this study. All stage I lesions and one stage II lesion were treated via transnasal endoscopic approach. A modified midfacial degloving approach was used for the removal of seven other stage II lesions, all six stage III lesions, and three stage IV lesions. A combined midfacial degloving-infratemporal fossa Fisch C-transcranial approach was the route chosen for the remaining two stage IV lesions. The complications encountered in the postoperative course include temporary facial palsy in one patient (following a Fisch C infratemporal resection), mild crusting in the nasal cavity in 8 patients, and facial paraesthesia in 6 patients whose tumours were resected via midfacial degloving, and rupture of the subpetrous part of the internal carotid artery in one patient. CONCLUSION: The suggested treatment of juvenile nasopharyngeal angiofibroma consists of an endoscopic transnasal approach for early stage lesions, and a modified midfacial degloving for almost all of the advanced lesions. The latter approach is very useful considering surgical exposure, duration of surgery, cosmetic outcome, and morbidity. It can be combined with an infratemporal approach or craniotomy if necessary.

Spontaneous cerebrospinal fluid rhinorrhea associated with empty sella: a transnasal-transsphenoidal repair of the fistula.

Spontaneous cerebrospinal rhinorrhea is a rare clinical condition. More commonly it develops due to cerebral tumors or hydrocephalus; it is seldom seen in association with empty sella syndrome. A sixty-three-year-old woman who presented with left nasal discharge was hospitalized on the suspicion of CSF rhinorrhea. Analysis of the nasal fluid revealed a clear color, a positive Pandy's test, and a positive result for glucose (72%). On magnetic resonance scans, herniation of the suprasellar cistern was observed into the sellar cavity, and the left sphenoid sinus was filled with contrast medium. The repair of the fistula was performed via a transnasal and transsphenoidal approach. The patient was followed-up for five years without any symptoms or recurrences.

[Orbital decompression by endoscopic transnasal and transantral approach in thyroid-associated ophthalmopathy].

OBJECTIVES: We evaluated the results of orbital decompression in patients with Graves' disease. PATIENTS AND METHODS: Orbital decompression was performed by endoscopic transnasal medial wall approach and transantral inferior wall approach in 18 eyes of 12 patients (8 males, 4 females; mean age 41 years; range 24 to 65 years). The degree of exophthalmos was evaluated with the use of the Hertel exophthalmometer preoperatively, and postoperatively in the 24th hour, first and third months. RESULTS: At the end of the third month, exophthalmos decreased by a mean of 4.4 mm (range 3 to 7 mm). Visual acuity and field defects improved considerably in all patients. Complications occurred in three cases (25%) including diplopia, displacement of one eye inferiorly, and maxillary sinusitis caused by the encroachment of the adipose tissue upon the ostium, respectively. CONCLUSION: With the increasing ease of surgical procedures and enhanced experience on the part of surgeons, successful treatment of exophthalmos has become possible with decreased complication rates.
