  • Title: [Treatment possibilities for malignant melanomas of the palate, nasal cavity and paranasal sinuses].
    Author: Scherer H.
    Journal: Laryngol Rhinol Otol (Stuttg); 1984 Jan; 63(1):9-10. PubMed ID: 6700332.
    Abstract:
    Malignant melanomas of the mucous membranes are rare. Statistics reveal an incidence of 8-9% in all head and neck melanomas. The tumour predominates in the nasal cavity and the paranasal sinuses in the statistic compiled by Eneroth and Lundberg and in our patients (60%), while Conley found that in the USA the oral cavity contains half of the melanomas. 34% only were situated in the nose. The prognosis is very poor, because of the hidden localisation, insufficient signs and high malignancy of these tumours. The five-year survival rate is 15-17%. The treatment of choice is extensive local electrodesiccation together with a radical neck dissection, or local cryosurgery. Maximal attention has to be given to the topmost lymph nodes at the base of the skull in melanomas of the nasal cavity. They can be removed after resection of the digastric muscle and elevation of the parotid gland. In case of a massive involvement of the lymphatic tissue at the skull base, the dorsal half of the vertical mandibula can be removed to gain broad access to the skull base, the pterygoid fossa and the retro-mandibular space. Neck dissection in cases of tumours of the buccal region and the alveolus must include the buccal lymph nodes concomitant with the facial vein. They are situated lateral to the horizontal part of the mandible.
