Median fistulaon the dorsum nasi is regarded as rare malformation.
A case of a female aged 22 of this malformation was described here. The fistula was accepted as the secondary fistule due to the infection of the dermoidcyst as it antecedents. Treatment by fistelectomy brought her some cosmetic improvement.
The authors discussed about the genesis of fistula on the dorsum nasi.

The author, I experienced a case of congenital Naso-Frontalhernia. The patient was a baby-boy who was a new-born 35 day. His physical characteristics were immature infant, anemia and situs inversus viscerum. For the treatment of hernia, I attempted to resect the hernial contents. Hernial opening was 1cm in diameter. Operative wound was covered with periosteum, muscles and skin. In post-operative stadium, this case was given a great deal of antibiotics. He completely cured on the 22 day. Recently, he has been healthful in the course of 8 months after the operation.

Two cases of the brain abscess are reported. The first case was recognized in a old man aged 64 without any obvious cause and recovened with non-operative treatment. It was very difficult to determine the affected side of the brain in this case. The second case, a boy aged 10, suffering from the abscess of the left sided temporal lobe as a complication of chronic otitis media with pseudo-cholesteatoma was treated surgically. The abscess was not able to be found until three times of operative procedures had been done. The agent of infection was shown to be staphylococcus.

A case of a male child aged 6 years, who had an unilateral, incomplete mandibulo-facial dysostosis associated with rare deformities of the ear, was reported. There was no significant family history concerning the congenital abnormalities. He was born at full term after what appeared to have been an uneventfull pregnancy. It was considered as one of causal factors that the early rupture of the faetal membran had made his birth very difficulf. His mental and bodily development was assured to be normal by the pediatric examination. On the otological and radiographic examination, we found that he had very complicated and various deformities on the left side of the head, face and neck.
Significant findings among these deformities are listed as follows.
1. A fissure, having been operated several days after his birth, extending laterally from the left angle of the mouth.
2. The grossly deformed left auricle, microcia, lop ear and auricular appendixes, displaced to caudo-ventrally at the angle of the lower jaw. There was an opening of soft external auditory meatus, covered with the deformed auricle, directed latero-cranially and ended at the ossal part.
3. Although asymmetry of palpebllar fissure was recognized, there were no manifest eye signs relating to this syndrom.
4. The atrophia of the left zygomatic arc and branch of the mandibule, as one of representative signs of dysostosis mandibulo-facialis, was marke also in this case.
5. Paralysis of the left facial nerve caused by the lesion in the facial canal.
6. On the radiographic examination of the left temporal bone, the poorly developed mastoid cells, antrum and tympanic cavity were recognized. Moreover, dislocation of the left pyramis, deformity of labyrinth capsule, and a large notch at the internal porus of the acoustic nerve, were demonstrated.
7. About an average of 30db hearing loss of bone conduction of the left ear was revealed by audiometrtic examination. Audiogram of the right ear was almost normal pattern.
Based on the radiographic findings of the left pyramis, we assumed the perceptive type hearing loss of the left ear to the conginital damage of the accoustic nerve.
A reviw of literatures was done, and the geneses of these congenital abnormalities were discussed.

It is well known that benign tumors originate seldom in the trachea. Especially the occurence of neurinoma in the trachea is extrmely rare. The authors reported a large pedunculated neurinoma originated from the 1st and 2nd tracheal ring in a 12 year-old-boy who complained chiefly incereasing dyspnea and cough, sputum and noisy stridor simultaneously. Tracheotomy was done first, and the tumor was exstirpated with forceps through the stoma of tracheotomy successfully. No subsequent complications, and no recurrens fur 1.5 years.

1. It is generally recognized that the transition part of the lip shows special attitude in some lesions such as Behget's syndrome. The author attempted to made the histological and histopathological studies on the rabbit lip to evaluate the reason of the above mentioned clinical speciality of the transition part comparing with the skin and the mucous membrane of the lip.
2. The fine structure of the rabbit lip with special regard to the distribution of the small vessels were observed by intravascular injection of resin or India ink. In the transitition part, the epitheliar layer is thickest, the papillae show marked development, and the small vessels in the connected tissue are abundant compared with the other parts.
3. The histological changes of the lip were observed in the rabbits which had been previously put in allergic state with subcutaneous injection of bovine blood serum and resensitized by the intraarterial injection of the antigen through the external maxillary artery. Slight serous inflammation was observed in each part.
4. When adrenalin was added as a modified element at the time of resensitization, the allergic histological change which showed the type of serous exudative inflammation increased generally.
5. In case that adjuvant was added, the change increased strikingly as serous exudative inflammation.
6. Through the above three experiments of sensitization, the allergic histological changes were observed stronger in the transition part than the other parts.
7. The similar allergic histological changes were observed also in the lung, heart and kidney.
8. From those results, the present author concluded that the special attitude of the transiton part of the lip against Behget's syndrome was probably explained by the allergic theory.
