The injection of paraffin for cosmetic purpose is an illegal method as it evokes late complications such as the development of grauuloma, migration of foreign body, inflammation, ulceration, embolic phenomenon, etc. However, paraffin has been used by some unauthorized people for the augmentation of the soft tissue, i.e. face, breasts, as they can easily reansform the body contour in a short time and paraffin is not expensive to do so. Paraffinoma has been reported frequently as a delayed or late complication of foreign body reaction in the field of plastic surgery. And various mehtods of its surgical treatment also has been a topic of plastic surgeon, as postoperative outcome is not satisfactory. As the nose is located at the center of face, the patients who are suffering from paraffinoma in nose could not conceal their deformed appearance by cosmetics. Therefore the only method of improvement is surgical removal of paraffinoma. Paraffinoma of nose has been removed by transcolumellar, infracartilaginous, intercartilaginous incision. However, complete removal of the foreign material does not seem to be possible, may leave complications such as hematoma and overlying skin necrosis, and the remaining foreign material does not permit symmetric appearance. We experienced excision of paraffinoma by direct incision on nasal dorsum. 3 patients with paraffinoma of nose were successfully treated without any complications by vertical elliptical excision on the dorsum of the nose, and scars on nasal dorsum were acceptable with satisfaction by patients. Therefore, the authors concluded that excision of paraffinoma by direct incision on nasal dorsum is a good method for symmetric resection of foreign material, low risk of complication.

Short nose is characterized by decreased distance from the nasion to tip defining point and increased nasolabial angle with increased nostril show. Lengthening the short nose is arguably the most difficult operation in aesthetic rhinoplasty. We have described here a simple and easy technique that lengthen the short nose by using silicone implant has been popular among Asian for augmentation rhinoplasty. Through open rhinoplastic approach, wide undermining of the nasal skin is performed to allow redraping of the skin over the lengthened skeletal framework without excessive tension. Alar cartilage is released from upper lateral cartilage and relocated caudally. After relocation of alar cartilage, silicone implant is inserted in subperiosteal pocket and immobilized by nonabsorbable suture material at dorsal aspect of septal cartilage. Narrow caudal end of implant is sutured between medial crura of alar cartilage which were caudally rotated. This implant not only raise the nasion but can move the tip-defining point caudally by keeping the alar cartilage in new position. Tip graft is done with conchal cartilage. We have got the satisfactory result in cosmetic aspect without any complications.

In patients having a short nose with a short septal length and/or severe columellar retraction, a septal extension graft is a good solution, as it allows the dome to move caudally and pushes down the columellar base. Fixing the medial crura of the alar cartilages to a septal extension graft leads to an uncomfortably rigid nasal tip and columella, and results in unnatural facial animation. Further, because of the relatively small and weak septal cartilage in the East Asian population, undercorrection of a short nose is not uncommon. To overcome these shortcomings, we have used the septal extension graft combined with a derotation graft. Among 113 patients who underwent the combined procedure, 82 patients had a short nose deformity alone; the remaining 31 patients had a short nose with columellar retraction. Thirty-two patients complained of nasal tip stiffness caused by a septal extension graft from previous operations. In addition to the septal extension graft, a derotation graft was used for bridging the gap between the alar cartilages and the septal extension graft for tip lengthening. Satisfactory results were obtained in 102 (90%) patients. Eleven (10%) patients required revision surgery. This combination method is a good surgical option for patients who have a short nose with small septal cartilages and do not have sufficient cartilage for tip lengthening by using a septal extension graft alone. It can also overcome the postoperative nasal tip rigidity of a septal extension graft.

Among several techniques to maintain the lengthened cartilagenous tip structure, septal extension graft with septal cartilage or rib cartilage is most widely used. But in many cases, nasal tip rigidity with unnatural appearance on smiling is one of the major drawbacks of septal extension graft. The authors used a piece of elastic cartilage graft harvested form ear that can act as a cushion buffer between alar cartilage and septum instead of directly fixing the alar cartilage to extended septum for obtaining a less stiff nasal tip with sufficient nasal tip elongation. We called this graft "derotation graft". Derotation graft was performed in 1197 patients via the open nasal approach. Among them, 432(36%) patients had preoperative short nose deformity and 765(64%) patients developed intraoperative cephalic rotation of the tip resulting from procedures for tip projection such as columellar strut. Excellent results were achieved in 1110(93%) patients. 87(7%) patients had unsatisfactory results requiring a revision surgery because of overcorrection or undercorrection of tip rotation, poor tip projection and visible graft on supratip. Derotation graft is a simple, and effective procedure for short nose correction preventing with less post-operative nasal tip rigidity.

Extravasation necrosis due to intravenously administered fluids and drugs is an increasing problem in hospital practice. The incidence of extravasation is variable but skin necrosis is a potentially devastating complication of intravenous therapy. Local injection of hyaluronidase has been recommended for several types of infusion extravasations. The previous studies found hyaluronidase to be effective in the prevention of necrosis following intradermal nafcillin, 12% dextrose, sodium bicarbonate, aminophylline or vince alkaloids.The objectives of the study are to determine the dosage of hyaluronidase which is effective in reducing extravasation necrosis caused by 10% calcium-gluconate and to establish how soon after this extravasation it must be given to retain its effectiveness.Study I evaluated control versus only normal saline group and normal saline with hyaluronidase groups (dose:75,150,300,450 units; all in volume 2 ml, treatment delay:immediate, 15-minutes delay, half hour delay, one hour delay, three hour delay). Size and rate of eschar were compared between groups. Study II was undertaken to examine the evolution of calcium-gluconate induced soft tissue injury in the rabbit. The histologic findings of extravasation sites were compared between groups. A statistically significant protective effect was found in the treated group versus the nontreated group within 15 minutes to 30 minutes. The most effective protection was achieved by the immediate injection of 300 units dosage of hyaluronidase.In conclusion, in the 10% calcium gluconate-induced extravasation, the given data suggest that one can expect the most protective effect with a 300 units dosage of hyaluronidase and within half-hour delay in the treatment group.
