ABSTRACT
Low-grade, polymorphic adenocarcinomas occur mainly in females and are usually associated with the small salivary glands of the palate. The tumors are malignant, but not aggressive. Regional neck as well as distant metastasis is rare and the mortality rate is low. Cribriform adenocarcinoma of the salivary glands is a rare tumor, currently ranked among low-grade, polymorphic adenocarcinomas of the salivary glands. However, it differs from carcinomas in this group as it metastasizes to the cervical lymph nodes and exhibits frequent primary localization in the small salivary glands at the base of the tongue. Despite the tendency to metastasize, patient prognosis remains favorable. A case of a 72-year-old woman with neck metastases of cribriform adenocarcinoma, of unknown primary origin, is reported. The primary tumor origin was ultimately determined using nuclear magnetic resonance, histological verification was difficult due to the presence of an intact mucosal cover over the tumor. Cribriform adenocarcinoma is known to have a number of characteristics in common with a typical low-grade, salivary gland adenocarcinoma. However, in contrast to low-grade adenocarcinomas, the tumor presented with neck lymph node metastasis.
ABSTRACT
A scar flap is formed with the pedicle at the lateral part of the columella base at the cleft side, that is, in the center of the affected region. It enables flap placement according to individual need. A prospective evaluation was performed in a group of 76 patients with cleft lip and palate, all operated on by the same plastic surgeon. The flap was used to improve the height of the columella and the extent of nasal mucosa on the frontal septum and on the nostril base in the vestibule. In the lip, the flap raised its height and improved proportionality. The average area of flap used in a unilateral deformity was 42 mm. Both flaps in a bilateral deformity were 77 mm. The average follow-up was 22.4 months. Neither local nor general complications were noted apart from a recurrence of the deformity of the nasal septum in 7.9% of patients. The nasal passage was improved in 59.9% of patients and normalized in 19.6% upon follow-up rhinomanometry, but nevertheless, only one third of patients overcame their dynamic stereotype of breathing by the mouth. Anthropometric measurements showed an absence of statistically significant differences between patients after surgery and healthy individuals in crucial parameters (nasal tip projection, length of columella, nasolabial angle, nasal angle, and lip angle). The loss of the stigmatizing deformity is based on rotation of the nasolabial angle in relation to the aesthetic axis of the face. Direct examination proved aesthetic and functional improvement as statistically significant in 92.1% of patients.
