Congenital Abnormalities*

Augmentation rhinoplasty is one of the most popular aesthetic procedures in Asians. Numerous alloplastic implants have been used, however alloplastic implants may cause many problems in nasal and perinasal areas because of thin soft tissue cover. For these reasons, an ideal implant should be nonpalpable, readily exchangeable and biocompatible. Among these alloplastic implants, Gore-Tex(R) is a polymer of carbon bound to fluorine composed of solid nodes connected by very fine fibers. It has been reported that this material become permeated and surrounded by mature connective tissue, forming a strong supporting envelop for the material, yet the implant is easily removed because of limited tissue ingrowth. Since it's development, Gore-Tex(R) has found many applications in the field of facial plastic and reconstructive surgery. From November, 2001 to December, 2002, Gore-Tex(R) implants were removed from 17 patients due to several problems such as; decreased dorsal height, tip deformity, chronic inflammation. The implants were very hard to remove and coinciding injury of the surrounding tissue were inevitable. An analysis of the length and thickness changes in these removed implants was made. The results showed, decrease in length and thickness with a volume loss averaging, 46.3% in 45x4.0mm implants, 49.3% in 50x5.0mm implants. In view of the experiences of 17 cases of Gore-Tex(R) implants in rhinoplasty, we have concluded that Gore-Tex(R) implants were structurally unstable, fibrovascular tissue ingrowth into pores were minimal, the implants were very hard to remove and the implants caused a postoperative volume reduction. Therefore, Gore-Tex(R) use in augmentation rhinoplasty should be approached with caution.

The reconstruction of hypopharynx after ablation of carcinoma is quite challengeable to plastic surgeons and requires the recovery of anatomic continuity and its own function such as swallowing and speech. Various surgical methods have been evolved through the years from local flap to microvascular free flap. The latter, obviously has improved the surgical outcome playing a main role in reconstruction of hypopharynx and universally been divided into visceral free transfer and fasciocutaneous free flap. Though lots of surgical options are reported depending on the shape and size of defect, patient's desires or surgeon's empirical background, no general agreement about the reconstruction of hypopharynx exists because the advantage of the one flap can be a disadvantage of the other and vice versa. The fasciocutaneous free flaps were used for reconstruction of hypopharynx in 18 patients, radial forearm free flap for 14 and anterolateral thigh perforator flap for 4 patients, respectively and indicated following that the first is the patients have partial defect that retain the remnant mucosa more than 50% of hypopharyngeal circumference. the second indication is the patient with previous abdominal operation and the third is the patient with risk of long ischemic time of transferred bowel. the last cases is the elderly patient with other comorbid condition even though the remnant mucosa are less than 50% of hypopharyngeal circumference. We have designed the flap to have a sufficient lumen of neohypopharyngeal diameter more than 4cm and the cephalic margin of hypopharynx be wider than caudal one, like a funnel shape, to eliminate the size discrepancy between the pharyngeal and esophageal lumen. The small triangular flap extension was designed in the caudal margin to prevent the distal enteric anastomosis site from the stricture, making the circumference of distal margin to be enlarged. In this paper, we contemplate our speculation for use of fasciocutaneous free flap for reconstruction of hypopharynx with surgical finesse to get a fine surgical outcome.

PURPOSE: Torus palatinus is a bony prominence at the middle of the hard palate. The size varies from barely discernible to very large, from flat to lobular. This oral exostosis is not a disease or a sign of disease, but if large, may be a problem. So, we present the clinical and histopathologic features and applied therapy and provide a comprehensive review of the rare case of the symptomatic exostoses. METHODS: A 37-year-old woman had slowly growing exophytic nodular mass of the bone that arises the midline suture of the hard palate. The patient was concerned about discomfort associated with movement of her tongue and about frequent irritation of the palatal mucosa during mastification of the hard food. The patient had a large, unilobulated torus palatinus. It extended from the area adjacent to the canine to a point beyond the junction with the soft palate. The mass was oblong in shape, measuring about 3cm long, 2cm wide, and 0.8cm in height. RESULTS: Before surgical intervention a CT was obtained for the sake of estimating the thickness of the bone between the exostoses and the maxillary antrum and floor of the nose. The surgical procedure was performed with the patient under general anesthesia. Removal of the exostosis was performed after midline mucoperiosteal incision with osteotome and diamond burr. Histologic finding revealed decalcified dense bony tissue, the presence of lacunae, and normal osteocytes. CONCLUSION: Surgical removal is recommended when one or more of the following condition exist: interference with the construction of prosthesis, interference with oral function, irritation or pathology of the overlying tissue, inability of the patient to maintain proper oral hygiene, and fear of malignancy or other psychologic trauma. We report a rare case of the torus arising in hard palate with symptoms.

PURPOSE: Retronychia is the embedding of the nail into proximal nail fold. Retronychia starts with disruption of the longitudinal growth of the nail. With the growth of a new nail, the old one is pushed upwards and backwards. This leads to embedding of the top nail into the ventral aspect of the proximal nail fold and results with chronic paronychia. We present a case of retronychia that was rarely reported in the literature. METHODS: A 46-year old female presented with a 3-month history of painful right first, 2nd, 3rd toenail changes. Although she was initially treated with broad spectrum antibiotics, she did not response to therapy. Later, she presented to our department because of progressively worsening pain that impaired her walking. Physical examination revealed with proximal nail fold erythema, painful swelling, yellowish nail discoloration, and distal onycholysis. Bacterial and fungus culture showed no organism. Treatment was surgical nail avulsion under local anesthesia. RESULTS: The postoperative course was uneventful. 10 months later, the patient had a normal growing nail and was free of symptoms. CONCLUSION: We report a case of retronychia on toenail. Retronychia is a proximal nail plate ingrowth into the proximal nail fold which is associated with multiple generations of nail plate misaligned beneath the proximal nail. Management consisted of simple avulsion of superimposed nail. Retronychia is suspected with a persistent paronychia, particularly in the setting of trauma. Avulsion of the top nail confirms the diagnosis and may be curative if the underlying nail appears healthy.

PURPOSE: According to various medical publications, it is believed that epinephrine should not be injected in fingers. However numerous articles show the successful use of local anesthetic with epinephrine in the digits. Epinephrine-mixed lidocaine solution enables to maintain a bloodless field for operation and provides long duration of local anesthesia when patient was wide awake. METHODS: From May 2009 to December 2009, ten patients underwent flexor tendon reconstruction with local anesthesia using epinephrine. No tourniquet was necessary. Before operation, all patients were injected with local anesthetics using 1% lidocaine 20 mL and 0.1% epinephrine 0.1 mL. RESULTS: There was no case of digital necrosis nor gangrene in the epinephrine injection. All 10 patients actively could move the finger through a full range of motion. All procedures were performed without sedation nor tourniquet and we could obtain a good vision of operative field and patients were comfortable. The patient make his or her fingers move through a full range of active motion before the skin is closed. Phentolamine was not required to reverse the vasoconstriction in any patients. CONCLUSION: The assertation that epinephrine should not be injected into the fingers is clearly no longer valid. The epinephrine injection allowed the authors to adjust flexor tendon surgery without risks associated with general anesthesia. It also enables to ensure longer anesthetic duration and bloodless operative field, and prevent post operative complications. In case of flexor tendon surgery, the use of epinephrine injection is recommended because of the advantages of local anesthesia.

PURPOSE: The fingertip is the most commonly injured part of the hand and its injury frequently results in avulsion or crushing of a segment of the nail bed and fracture of the distal phalangeal bone. Restoration of a flat and smooth nail bed is essential for regrowth of a normal nail, which is important not only for cosmetic reasons but also for tactile capability of the fingertip. It is also anatomical reduction of the distal phalanx to promote patient's cosmetics and prevent nail bed deformity. Absence or no replacement of the nail plate results in obliterated proximal skin fold. When the avulsed nail plate cannot be returned to its anatomic position or when it is absent, we use a synthetic material for splinting the nail bed and alternative reductional method for distal phalangeal bone fracture, especially, instead of hardwares. METHODS: From January of 2006 to June of 2009, a total of ten patients and fourteen fingers with crushing or avulsion injuries of the fingertip underwent using the artificial nails for finger splint. We shaped artificial nails into the appropriate sizes for use as fingernail plates. We placed them under the proximal skin fold and sutured to the fold proximally and to the lateral and medial edges of the nail bed or to the distal fingertip. Our splints were as hard as K-wire and other fixation methods and more similar to anatomic nail plates. Artificial nails were kept in place for at least 3 weeks. RESULTS: No artificial nail related complication was noted in any of the ten cases. No other nail fold or nail bed complications were observed, except for minor distal nail deformity because of trauma. CONCLUSION: In conclusion, in order to secure the nail bed after injury and reduce the distal phalangeal bone fracture, preparing a nail bed splint from a artificial commercial nail is a cheap and effective method, especially, for crushed or avulsion injuries of the fingertip.

PURPOSE: Schwannoma, a benign peripheral nerve tumor, is slow-growing, encapsulated neoplasm that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma occurring in the superficial radial nerve rare. This is a report of our experience with schwannoma arising from the superficial radial nerve with neurologic symptom. METHODS: A 55-year-old woman presented with eight-month history of progressive numbness and paresthesia in dorsum of the thumb and index finger. Physical examination revealed a localized mass on the midforearm. Sonographic examination showed an ovoid, heterogenous, hypoechoic lesion, located eccentrically in related to the superficial radial nerve. The lesion was mobile in the transverse but not in the longitudinal axis of the nerve, which was thought to favour schwannoma rather than neurofibroma. At operation, a 20 x 15 mm ovoid, yellowish grey mass was seen arising from the superficial radial nerve. The tumor present as eccentric masses over which the nerve fibers are splayed. Using operating microscope, the tumor was removed, preserving the surrounding nerve. RESULTS: Histology confirmed that the mass was a benign schwannoma. There were no postoperative complications. After two months the patient had no clinically demonstrable sensory deficit. CONCLUSION: An unsusual case of a schwannoma of the superficial radial nerve is presented. In case with neurologic symptom, prompt surgical decompression must be made to prevent further nerve damage and to restore nerve function early.

Craniosynostosis is the term that designates premature fusion of one or more structures in either crania1 vault or cranial base. Various surgical methods including frontal bone advancement and crania1 vault remodeling have been developed in order to correct craniosynostosis. Nowadays, distraction osteogenesis technique has been successfully used by many plastic surgeons. We have experienced several patients with craniosynostosis who had surgical correction using distraction device. All patients obtained satisfactory results and no relapses were observed during the follow-up period. However, previous approaches have required bicoronal incisions and extensive scalp mobilization for adequate exposure. The specific technique of using the endoscope in assisting and perfoming osteotomies and inserting distraction devices made less blood loss, less blood transfused, less operative time, shorter length of stay, overall less expenses, and less visible scars. In conclusion, the endoscopic technique for early correction of craniosynostosis is safe and can be used for correction of other various deformities of craniosynostosis. Because of the minimal invasive technique, the patients with craniosynostosis can be treated at a very early age.
