Prelacrimal Recess Approach for Maxillary Sinus Inverted Papilloma: Preliminary Study / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES@#Various surgical approaches have been employed for the complete resection of inverted papilloma (IP) of the nose and paranasal sinus. Sacrificing the inferior turbinate (IT) and nasolacrimal duct (NLD) is often unavoidable due to the anatomy of maxillary sinus. However, the prelacrimal recess approach (PLRA) provides a wider entrance to the maxillary sinus without the ablation of NLD and IT. We present seven cases of IP successfully treated by the PLRA.SUBJECTS AND METHOD: We collected data from seven different cases involving patients who underwent resection of IP by means of the PLRA from 2016 to 2017. If the lesion could not be removed first via middle meatal antrostomy (MMA), then PLRA was attempted. The surgical specimens were all confirmed to be IP.@*RESULTS@#Preoperative imaging studies demonstrated that the lesions of IP were located mainly in the maxillary sinus. All of the seven patients had unilateral lesions and all tumors were completely resected via PLRA. The follow-up ranged from 3 to 24 months, during which no recurrence or complications were observed in any of the seven patients.@*CONCLUSION@#PLRA provides an adequate operation field without unfavorable scars. It allows the preservation of sinus structure and function. PLRA is feasible and can be used for the diffuse maxillary sinus IP.

A Case of Hepatocellular Carcinoma Metastasis to the Dorsal Tongue / 대한이비인후과학회지

Hepatocellular carcinoma (HCC) is a common neoplasm, and its metastasis to the head and neck area is rare. We herein describe a unique case of HCC metastasis to the dorsal tongue. A 54-year-old male who was already diagnosed with HCC visited our hospital complaining of dysphagia and a progressively enlarging dorsal tongue mass. We operated to excise on the mass using CO₂ laser including mucosal margin and deep margin. The diagnosis of HCC metastasis was confirmed immunohistochemically. After 2 weeks of follow-up, the patient did not exhibit any evidence of complication and could eat orally without any problem. Further treatment to the other metastatic lesion was rejected, and the patient was followed up for more than six months. We introduce this first case of metastatic HCC in the dorsal tongue. With the extended life expectancy of HCC patients, the incidence of rare metastasis is expected to increase.

A Case of Fish Bone-Induced Submandibular Gland Stone / 대한이비인후과학회지

Sialolithiasis is the most common disorder associatd with major salivary glands. It may form in any salivary glands or ducts, but is reported to occur more often in the submandibular gland than in the parotid or sublingual gland. Although the pathogenesis is not perfectly revealed, there appear to be several factors that predispose the submandibular gland duct to be a common site of sialolithiasis. Sialolithiasis occurs as a consequence of the precipitation of calcium salts around a central nidus of desquamated epithelial cells, inflammatory cells, mucoid gels or foreign body. However, it is not a common thing that foreign body entered into the salivary duct through duct orifice may act as the initiating factor. We have recently experienced a case in a 52-year-old female, in which sialolithiasis seems to have formed due to a a foreign body, a fish bone, in the right submandibular gland duct.
