1/131. Transnasal endoscopic repair of congenital defects of the skull base in children.

    OBJECTIVE: To examine imaging findings and methods of endoscopic treatment of congenital skull base defects in children. DESIGN: Retrospective study and case series. SETTING: Academic tertiary care center. patients: Four patients (aged 12 and 14 months and 8 and 13 years) were included from 1995 to 1997. Three presented with a nasal glioma, which was recurrent in 1 case. The fourth patient presented with bacterial meningitis due to a spontaneous cerebrospinal fluid leak. Computed tomography and magnetic resonance imaging were used to locate the defect of the skull base. INTERVENTION: Transnasal endoscopic resection of the glioma or the meningocele, with immediate repair of the skull base defects using free mucosal flaps and/or pediculized mucosal flaps and/or conchal cartilage together with fibrin glue and nasal packing during a 3-week period. RESULTS: None of the 4 patients has experienced recurrent cerebrospinal fluid leaks or postoperative meningitis. CONCLUSIONS: The transnasal endoscopic repair of congenital meningoceles is a reliable technique in select pediatric patients. Computed tomography and magnetic resonance imaging provide information that can be used to help the surgical procedure.

2/131. Nasal haemangiopericytoma: report of two cases with literature review.

    Haemangiopericytoma (HPC) is a rare vascular tumour produced by proliferation of pericytes. One hundred and thirty-three cases of HPC have been reported in the nose and the paranasal sinuses. We present two more cases. Wide surgical excision via lateral rhinotomy, midfacial degloving, or endonasal removal is the treatment of choice. radiotherapy has been used post-operatively in cases of incomplete removal. life-long follow-up is required to evaluate local recurrence and late metastases.

3/131. Application of artificial dermis prior to full-thickness skin grafting for resurfacing the nose.

    Two patients with nasal skin defects resulting from excision of rhinophyma and multiple angiofibromas were treated with artificial dermis followed by full-thickness skin grafts taken from the postauricular region. The secondary skin grafts took completely in both patients, and the postoperative results were excellent. Although a two-stage operation is required, application of artificial dermis prior to full-thickness skin grafting is a reliable method for resurfacing the nose.

4/131. Superiorly based nasolabial interpolation flap for repair of complex nasal tip defects.

    BACKGROUND: Reconstruction of full-thickness defects of the nasal tip is one of the most challenging aspects of cutaneous oncologic surgery. It is imperative that the cutaneous surgeon be intimately familiar with all the available surgical options to provide for the best postoperative outcome. OBJECTIVE: To describe an additional surgical option for reconstruction of complex small to medium-size full-thickness nasal tip defects involving more than one cosmetic unit. methods: Three patients underwent reconstruction of complex full-thickness nasal tip defects using a two-stage nasolabial interpolation flap. RESULTS: Closure of each surgical defect was achieved with the two-stage nasolabial interpolation flap with good cosmetic results in the first postoperative year. CONCLUSIONS: The two-stage nasolabial interpolation flap is a useful tool in the reconstruction of complex full-thickness defects of the nasal tip.

5/131. Management of sinonasal hemangiopericytomas.

    The purpose of the present study is to report four cases of sinonasal hemangiopericytoma (HP) diagnosed and treated in our department between 1987 and 1998. The pretreatment findings and the treatment are described and discussed in the light of the literature. HP are unusual vascular tumors, featuring pericytes distributed around normal vascular channels. Two of these four cases were located in the nasal cavity and the other two were located in the maxillary sinus. Inside the nasal cavity, HP presented as a protruding reddish-gray mass with marked bleeding on contact. Electron microscopy and immunohistochemical techniques are essential for diagnosis and to distinguish HP from other sarcomatous tumors. Preoperative assessment included routine CT, MRI, arteriography and selective embolization. These tumors must be treated surgically with complete excision. An endonasal approach was performed in two cases of intranasal HP, while a combined external-endonasal approach was required for the other two cases of HP.

6/131. Angiectatic nasal polyps that clinically simulate a malignant process: report of 2 cases and review of the literature.

    BACKGROUND: Approximately 5% of inflammatory or allergic sinonasal polyps develop extensive vascular proliferation and ectasia with deposition of pseudoamyloid. These so-called angiectatic nasal polyps (ANPs) can grow rapidly and exhibit an aggressive clinical behavior that could simulate malignancy preoperatively. OBJECTIVE: To systematically address the differential histologic diagnosis of ANPs. methods: We evaluated by light microscopy, immunohistochemistry, and electron microscopy biopsy and resection specimens from 2 large ANPs (8 and 10 cm in diameter) that presented in 2 adult men with life-threatening epistaxis and facial deformity, respectively. RESULTS: The tumors were firm, lobulated, and covered by smooth, partially ulcerated mucosa. Histologically, clusters of dilated, thin-walled blood vessels embedded in pools of congo red-negative eosinophilic material, associated with patchy necrosis and atypical stromal spindle cells, were seen. Electron microscopy and immunohistochemistry (CD34, factor viii) confirmed the endothelial nature of the cells lining the spaces, whereas the atypical stromal cells were classified as myofibroblasts. CONCLUSIONS: These 2 cases represent extreme examples of ANPs that clinically simulate a malignant process. awareness of the histological features of ANPs should prevent confusion of such lesions with other vascular or spindle cell lesions of the nasopharynx that would require different treatment and carry a different prognosis.

7/131. chondrosarcoma of the nasal septum.

    chondrosarcoma of the nasal septum is a rather uncommon tumour. Therefore, only limited numbers of cases have been described in the literature. This paper reveals one more case observed at the ORL department of Dicle University. In the present case, by using a transnasal and transpalatal approach, total resection of the tumour was performed in conjunction with postoperative radiotherapy.

8/131. The use of intensity modulated radiotherapy for the treatment of extensive and recurrent juvenile angiofibroma.

    These case series are presented to describe the application and advantages of intensity modulated radiotherapy (IMRT) for the treatment of extensive and/or recurrent juvenile angiofibroma. Two patients were diagnosed with recurrence at 11 and 13 months postoperatively, and one was surgically unresectable. The affected areas included the base of skull, cavernous sinus, pterygopalatine fossa, infratemporal fossa, posterior orbit and nasopharynx. Highly conformal IMRT was delivered with limited radiation doses to the optic nerves, optic chiasm, brainstem, brain, spinal cord, lens, retina, mandible, and parotid. The total dose delivered to the tumor varied from 3400 to 4500 cGy. The tumor shrunk radiographically in all three cases and there was no endoscopic evidence of disease in two cases at 15 months and 40 months. There was no acute toxicity. Late toxicity was limited to one episode of epistaxis and persistent rhinitis in one patient. In conclusion, IMRT provides several advantages over conventional radiotherapy in the treatment of recurrent juvenile angiofibroma.

9/131. Extraintestinal polyps in peutz-jeghers syndrome: presentation of four cases and review of the literature. Deutsche Peutz-Jeghers-Studiengruppe.

    peutz-jeghers syndrome (PJS) is a rare hereditary disorder characterized by hamartomatous polyps in the gastrointestinal tract and typical pigment lesions. Extraintestinal polyps have rarely been reported. Possible sites include the respiratory tract, urogenital tract, and gallbladder. We here describe four cases of extraintestinal polyps in PJS patients and review the literature on the need for operative therapy of extraintestinal polyps in PJS. Three nonrelated patients were examined who had PJS and polyps in the gallbladder; the fourth patient had PJS and recurrent choanal polyps. Surgery has so far been performed only for symptomatic polyps: one laparoscopic cholecystectomy and removal of the choanal polyps for recurrent infections of the respiratory tract. The remaining two patients reported no symptoms from the extraintestinal polyps. No malignant transformation was found in these patients, nor has such been reported in the literature on PJS. The frequent observation of this manifestation in our patients raises the question of clinical management: Is prophylactic surgery indicated? Since malignant transformation of PJS polyps in the intestine is extremely rare we see no reason for operative therapy as long as the polyps are small and asymptomatic. Regular sonographic controls are recommended since the risk of malignant transformation cannot be ruled out at present.

10/131. Schwannoma of the nasal septum: a case report with review of the literature.

    Schwannomas are neurogenic neoplasms rarely found in the sinonasal tract, where localization to the nasal septum is exceedingly rare (only 11 cases have been described in the western literature). We report the case of a 29-year-old white male with a schwannoma completely filling the left nasal fossa and arising from the bony part of the septum. A computer tomography (CT) scan and a biopsy suggestive of benign schwannoma were obtained before the lesion was removed by a degloving approach. The preoperative diagnosis of nasal septum schwannoma was confirmed. The patient is asymptomatic and without endoscopic evidence of recurrence 7 years after surgery. A review of the literature with particular emphasis on the clinical presentation, histological features, differential diagnosis and therapeutic options for such a rare lesion is included.
