[Mastering endonasal dacryocystorhinostomy].

A persistent, symptomatic lacrimal duct stenosis is treated by dacryocystorhinostomy (DCR), with external (EX) or endonasal (EN) access. The basic indication is the same in all cases and either route can be used. The EX route seems better in terms of speed of surgery, learning curve and cost. It is logical to use the external route to treat the disorder when it is associated with a lacrimal sac diverticulum, an irreducible stenosis of the union canal, or a canthopexy. The EN route has been shown to be worth consideration whenever there is a nasal sinus disorder that can be repaired at the same time. Moreover, it is indicated in a rare case of lacrimal abscess that cannot be treated medically, where the risk of scarring would contraindicate standard surgery, or when DCR is recurrent. A series of prospective randomized studies is needed to determine whether the route materially influences the outcome. Until then, it is best to have both methods available for an unbiased case-by-case decision.

[Squamous cell carcinoma in a thyroglossal duct cyst].

OBJECTIVE: To present a case of squamous cell carcinoma developed on a thyroglossal duct cyst in an adult patient. Modalities of treatment and prevention are discussed. PATIENT AND METHODS: A 55-year-old woman had a thyroglossal duct cyst since childhood. Surgical resection had not been performed because of parental refusal. RESULTS: Diagnosis of malignant degeneration was suggested by an increase in volume associated with cervical pain. Surgery was incomplete because of carotid artery and laryngeal involvement. Postoperative radiotherapy was given. At two years follow-up, local progression was controlled by palliative chemotherapy. DISCUSSION: For most authors, the risk of recurrent infections is the main reason for surgical resection of a thyroglossal duct cyst during childhood. The risk of malignant degeneration is generally not put forward. It is rather uncommon for carcinoma to develop on a thyroglossal duct cyst. The risk is probably underestimated because surgery is generally performed early in childhood. CONCLUSION: This observation of malignant degeneration emphasizes the importance of surgical resection of thyroglossal duct cysts during childhood. We discuss treatment in the event of malignant degeneration.

[Hemangiomas and superficial vascular malformations of the face and neck].

Hemangiomas and superficial vascular anomalies of the head and neck form what usually calls the angiomas. Many terms exist in the literature for that reason the classification of the ISSVA, admitted by most of the doctors, helps us in naming the different anomalies. The processing of this pathology needs a multidisciplinary collaboration with doctors of different specialties. The evolution of the radiological, surgical techniques of laser, and who knows, of the research, allows to hope us to cure some of the particularly dangerous anomalies like the arteriovenous malformations. We presented here the different technics used in 2001 in the management of hemangioma and superficial vascular anomalies insisting on a multidisciplinary approach.

Aneurysmal bone cyst in the sphenoid bone: treatment with minimally invasive surgery.

Aneurysmal bone cysts are vascular lesions that destroy and expand bone. We report a recently treated case of an aneurysmal cyst of the sphenoid bone. A 14-year-old girl presented with frontal headaches, bouts of nausea, and vomiting. Computed tomography and magnetic resonance imaging showed typical features of an aneurysmal bone cyst. Arterial embolization was undertaken before surgery. The endoscopic transnasal procedure used allowed the complete removal of the aneurysmal bone cyst. This use of minimally invasive surgery makes this case of interest to surgeons of the skull base and sinuses.

[Endonasal dacryocystorhinostomy (DCR) with protected drill].

PURPOSE: To analyze the interest of protected drills to perform endoscopic endonasal DCR. MATERIAL AND METHODS: [corrected] Fifty patients suffering from chronic epiphora were operated successively. None of those patients had had prior nasal surgery. The same surgeons (BF and ER) did the surgical procedure for all the cases. The technical steps were: endoscopic visualization of the middle meatus and evaluation of the anatomic variations of the nose; identification of the lacrymal bag with a 1 mm light in the canaliculus; unciformectomy; the maxillary bone was drilled with a 3.2 mm bit (straightshot Xomed), protected and irrigated; the lacrymal bag was opened by cissors and the flap was pushed in the ethmoid and coagulated. RESULTS: The suction-irrigation system was efficient to clean the surgical site, with a good endoscopic control. The protected bit didn't damage the 4-mm optics and the septal wall mucosa, even in narrow noses. The staightshot bit (Xomed) was tough enough to drill the maxillary bone in only 68 % of the surgical cases. In 28 % the drilling was unsatisfactory and in 4 % it was inefficient. The functional results at 6 month were good in 85 %. There was no difference between normal and narrow noses. CONCLUSION: The concept of protected bits perfectly matches the endoscopic endonasal DCR. The visual comfort and security of the surgical procedure are increased. Short term results are equivalent to external DCR, but are rather inefficient and expensive.

[Is the uncinate process resection the key to endonasal dacryocystorhinostomy?].

Endonasal dacryocystorhinostomy is technically more difficult than the classic method and apparently less rational. The nasal fossa is a variable and potentially dangerous anatomic region. The uncinate process "opens the door" to the middle meatus and covers, in almost all cases, the junction between the lacrymal bone and maxillary concha. A marker almost always found. Uncinate process resection is a natural way to access the lacrymal apparatus. Associated with transillumination of the lacrymal duct, uncinate process resection, is in our opinion, a reliable and, most importantly, reproducible method for an endonasal approach to the lacrymal sac. With resection, endonasal dacryocystorhinostomy becomes a simple, safe and rapid procedure.

Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses: report of one case and a review of the literature.

Chondromyxoid fibroma is a rare benign tumor that usually occurs in the long bones. A 50-year-old patient presented with chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses. This is the fourth case reported to date in the literature. The clinical manifestations of the tumor were very limited, and the appearance at rhinoscopy was misleading. Radiologic imaging showed a soft tissue lesion invading the adjacent bony structures and the dura mater. Surgery was performed by a combined team of otorhinolaryngologists and neurosurgeons, and total excision of the tumor was achieved. The histologic diagnosis of this tumor is difficult because of its similarities to chondrosarcoma. [Editorial comment: The authors concisely review management of this rare tumor, emphasizing that complete surgical excision, rather than curettage, is required for long term control.]
