The displacement of an entire tooth into the adjacent anatomical area is an uncommon complication of a tooth extraction. We encountered a 23-year-old woman who had previously undergone surgery under local anesthesia to remove the lower third molar about 12 weeks prior and the upper third molar was extracted 2 days prior to visiting this hospital. Upon admission, she complained of a swallowing discomfort and a mouth opening limitation. Panoramic radiograph and a CT scan revealed a displacement of the entire tooth into the lateral pharyngeal space. The tooth was retrieved via the transoral approach under general anesthesia. The removed tooth had an indentation formed by a dental bur. Therefore, it was concluded that the tooth displaced into the lateral pharyngeal space was the lower third molar. This report describes an unusual case of a third molar that was displaced into the lateral pharyngeal space with a review of the relevant literature.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.

Berardinelli lipodystrophy syndrome is a rare autosomal recessive disorder, characterized by loss of body fat, muscular hypertrophy, acanthosis nigricans, hepatomegaly, hyperlipidemia, insulin resistant diabetes, and elevated metabolic rate. The mechanism(s) responsible for these abnormalities is not known. We report a forteen-month old girl with Berardinelli Lipodystriphy Syndrome, who had signs above mentioned, with a brief review and its related literatures.

7.Postoperative Refractive Outcomes of Biometric Formulas in Phacovitrectomy with Gas Tamponade
Korean Journal of Ophthalmology 2023;37(4):322-327
Purpose:
To investigate the refractive accuracy of intraocular lens (IOL) power calculation for biometric formulas in phacovitrectomy.
Methods:
This retrospective study included 357 eyes of 357 patients who underwent phacovitrectomy using four commonly available IOL power formulas: Hoffer Q (87 eyes), Holladay 1 (78 eyes), Holladay 2 (91 eyes), and SRK/T (101 eyes). The mean refractive error (ME) and the mean absolute refractive error (MAE) were calculated based on the predicted postoperative refraction error, and they were compared using analysis of variance test. Subjects were divided into high myopic eyes (axial length, ≥26 mm) and nonhigh myopic eyes (axial length, <26 mm).
Results:
The ME and the MAE after phacovitrectomy did not show a significant difference among the four IOL power formulas (p = 0.546 and p = 0.495, respectively). There was no significant statistical difference in formulas when the eyes were grouped into high myopia and nonhigh myopia (ME: p = 0.526 and p = 0.482, respectively; MAE: p = 0.715 and p = 0.627, respectively). The ME showed myopic shift in all formulas regardless of IOL formula used. The ME showed greater myopic shift in high myopia group than nonhigh myopia group in all formulas.
Conclusions
Our study did not find evidence for superiority of any formula in phacovitrectomy. However, in phacovitrectomy, possible myopic shift should be considered for IOL power calculation. Especially, in phacovitrecotmy in patients with high myopia, more myopic shift should be considered when selecting IOL.
