[The Antia-Buch flap technique in reconstruction of marginal ear defects]. / Le lambeau d'Antia-Buch dans la reconstruction des pertes de substance partielles de l'hélix.

INTRODUCTION: The aim of this study was to evaluate the results of ear defect reconstruction using the Antia-Buch flap technique and to compare it to other techniques described in international literature. MATERIALS AND METHODS: We performed 19 Antia-Buch flaps between November 1998 and November 2002: 15 cases after neoplastic treatment and four post-traumatic cases. Defect ranged between 15 and 40 mm. Between 30 and 40 mm, we used Fata's modification. The final assessment took into account patient satisfaction, cosmetic aspect of reconstruction assessed by the medical team, the presence of a notch at the helical rim and the degree of microtia. RESULTS: All ear reconstructions were successful. No complications were reported. Fata's modification was used for eight patients. All the patients were satisfied with the result in spite of a systematic microtia. The cosmetic aspect was considered as good for 16 patients, average for three. Nine patients presented with a notch at the helical rim. DISCUSSION: Reconstruction using the Antia-Buch flap is a simple and fast operative technique performed in a single operation under local anesthesia. It allows for a harmonious reconstruction of the helix and auricle with a tissue of same nature, and only a tiny cicatricial ransom, systematic microtia and frequent notch on the helical rim.

[Malignant triton tumor of the sinonasal tract]. / Tumeur triton ethmoido-nasale.

INTRODUCTION: The combination of a malignant peripheral nerve sheath tumor with rhabdomyosarcomatous elements has been termed Malignant Triton Tumor (MTT). This tumor was first reported in 1932 and the prognosis was poor. Involvement of the sinonasal tract is rare with only 10 case reports. CASE: We report the case of a 80-year-old woman who presented an obstruction of the right nasal fossa which developed over several years without anosmia. She consulted because of recurrent epistaxis. The CT-scan revealed a tumor occupying the right ethmoid the right maxillary sinus and the homolateral nasal fossa. Resection was achieved via an extended mediofacial route. The histological diagnosis was low-grade schwannosarcoma with a discretely extended rhabdomyosarcomatous component, i.e. MTT. No complementary treatment was given. Eight months later, the tumor relapsed with cerebral involvement. Despite new surgery with two teams, a neurosurgical and a radiotherapy team, the tumor relapsed at the ethmoid-nasal level. After five years, the patient is alive with local progression without metastasis. DISCUSSION: MTT of the sinonasal tract is a rare disease that clinicians should be aware of and that must be included in the differential diagnosis of malignant lesions involving the sinonasal tract. Most of the reported cases involving localizations other than the ethmoidonasal cavities, are associated with von Recklinhausen neurofibromatosis and occurr in young subjects (mean age 35 years). There have however been sporadic cases, mainly in older women or after radiotherapy. The prognosis is somewhat better for ethmoidonasal localizations.

Tumour of the juxtaoral organ.

The juxtaoral organ is a normal and constant structure of the oral cavity. It consists of benign epithelial nests. We describe an intraoral tumour of the juxtaoral organ in a child. The tumour was not diagnosed after clinical and radiological examinations because it is extremely rare. A histological examination revealed a tumour of the juxtaoral organ, presumed to be neuroid hamartoma. This is only the second time that a tumour of the juxtaoral organ has been described in a child. We also describe the location, the embryology, the histology and the function of this organ. This is important because this structure can be confused with carcinomas of the oral cavity when examining frozen sections.

[Cysts from the first branchial cleft. Apropos of a case ]. / Kystes de la première fente branchiale. A propos d'un cas.

We describe a case of branchial cyst from the first branchial cleft in an 8-year-old patient, emphasizing the diagnostic difficulties of this type of lesion and the clinical aspects as well as the details of surgical treatment. The embryogenic origin and the anatomic relation with the facial nerve is recalled. Surgical treatment is indicated.
