A Case of Sebaceous Trichofolliculoma on the Right Cheek / 대한이비인후과학회지

Sebaceous trichofolliculoma is a rare benign tumor and represents a variant of trichofolliculoma. Up to now, only 5 cases of sebaceous trichofolliculoma were reported in Korea. It generally presents as a centrally depressed solitary tumor and occurs in areas rich in sebaceous lobules. Microscopically, it shows cystic cavities with or without keratin-filled portion and sebaceous lobules. The lobules are connected to the cystic wall. We report a case of infected sebaceous trichofolliculoma on the right cheek accompanied by a unilateral microtia in a 16-year-old man. The patient was treated with oral antibiotics and surgical excision. By summariz-ing 12 past cases, 6 Korean and 7 international, we have put together clinical features of Se-baceous trichofolliculoma.

What Really Decides the Facial Function of Vestibular Schwannoma Surgery?

OBJECTIVES: To find the main cause of facial nerve dysfunction in vestibular schwannoma (VS) surgery and review the prognosis of facial function in relation to tumor size, preoperative facial function and surgical approach. METHODS: We reviewed the surgical outcome of 134 patients with VS treated in our department between 1994 and 2008. All patients included in the study had postoperative facial paralysis after surgical management of their VS. There were 14 women and 7 men. The mean age was 48.5 years, with a mean follow-up period of 57 months. RESULTS: Twenty-one patients (sustained facial palsy, 4; newly developed facial palsy, 17) had facial nerve paralysis after surgery: ten patients in large VS and eleven patients in small VS. In large VS group, 4 patients had facial nerve function of HB grade II, 3 patients had HB grade III, and 3 patients had HB grade IV. In small VS group, 9 patients had HB grade II and 2 patients had HB grade IV. Middle cranial fossa approach rather than translabyrinthine approach for the preservation of hearing, led to facial nerve deterioration and the patients who had facial nerve paralysis perioperatively, had resulted in permanent facial paralysis. CONCLUSION: The tumor size in VS is certainly one of the most important prognostic factors. However, VS tumor size alone should not be considered a unique prognostic indicator. The surgical approach used, which may be related to tumor size, based on the surgeon's experience, can be a deciding factor, and the status of the facial nerve injured by the tumor can influence postoperative facial nerve function.

Features of Facial Asymmetry Following Incomplete Recovery from Facial Paralysis

PURPOSE: The purpose of this study is to investigate peculiar patterns of facial asymmetry following incomplete recovery from facial paralysis that require optimal physical therapy for effective facial rehabilitation, and to decrease the incidence of avoidable facial sequelae. MATERIALS AND METHODS: This study involved 41 patients who had facial sequelae following the treatment of various facial nerve diseases from March 2000 to March 2007. All patients with a follow-up of at least 1 year after the onset of facial paralysis or hyperactive function of the facial nerve were evaluated with the global and regional House-Brackmann (HB) grading systems. The mean global HB scores and regional HB scores with standard deviations were calculated. Other factors were also analyzed. RESULTS: Four patterns of facial asymmetry can be observed in patients with incomplete facial recovery. The most frequently deteriorated facial movement is frontal wrinkling, followed by an open mouth, smile, or lip pucker in patients with sequelae following facial nerve injury. The most common type of synkinesis was unintended eye closure with an effort to smile. CONCLUSION: We described common configurations of facial asymmetry seen in incomplete recovery following facial nerve injury in an attempt to develop an optimal strategy for physical therapy for complete and effective facial recovery, and to decrease the incidence of avoidable sequelae.

A Case of Orbital Apex Syndrome Related to Sphenoid Fungal Sinusitis / 대한이비인후과학회지

Orbital apex syndrome (OAS) has been described previously as a syndrome involving damage to the oculomotor nerve, trochlear nerve, abducens nerve, and ophthalmic branch of the trigeminal nerve in association with optic nerve dysfunction. The conditions and symptoms of OAS are characterized by blindness, fixed dilated pupils, proptosis, ptosis of the eye and ophthalmoplegia. Infectious diseases involving the central nervous system, paranasal sinuses, and periorbital structures may lead to an OAS. We recently experienced a rare case of sphenoidal aspergillosis, which damaged the adjacent cavernous sinus structures and led to the definite symptom of OAS in a 75 year-old female. We present this rare case with a brief review of these disease's entities.
