Risk Factors for Emergency Room Visits Among Patients With Head and Neck Cancer: A Longitudinal Cohort Study Within the Korean Healthcare System.

Objectives: A substantial proportion of patients with head and neck cancer (HNC) require emergency room (ER) visits or unplanned hospitalizations during or after treatment with various modalities. We investigated HNC cases that necessitated ER visitation after cancer treatment, aiming to identify potential risk factors in the context of the Korean healthcare system.

Methods: This single-center cohort study examined patients with HNC who received cancer treatments at Samsung Medical Center in 2019 (n=566).

A Modified Approach for Preventing Anterior Glottic Web Formation Using Mitomycin C in Bilateral Vocal Fold Lesions.

Laryngeal keel insertion, mucosal suture, application of mitomycin-C (MMC), and staged operations are approaches to prevent the anterior glottic web, but there are limitations. Our study suggests a modified approach to prevent the formation of an anterior glottic web. This retrospective single-institution tertiary center study (N = 23) involved the simultaneous removal of bilateral vocal fold lesions with topical MMC application.

Thyroid Gland Flap for Prevention of Pharyngocutaneous Fistula After Total Laryngectomy.

ObjectivesPharyngocutaneous fistula (PCF) is the one of the major complications after total laryngectomy (TL), which can result in saliva leakage, rupture of major vessels, and increased hospitalization. Several flaps have been tried to prevent PCF during TL, and they are usually associated with donor site morbidity and uncertain viability in case of previously irradiated patients. This study aimed to report a novel bilateral pedicled thyroid gland flap (TGF) technique for delicate and effective reinforcement of neopharynx suture line after TL.

A novel FGFR2 mutation in tyrosine kinase II domain, L617F, in Crouzon syndrome.

The purposes of this study were to find a novel mutation of FGFR2 in Korean Crouzon syndrome patients and to identify the functional consequences of this mutation. The samples consisted of 16 Crouzon patients. Peripheral venous blood was collected from the patients.

Differential diagnosis for inappropriate upper incisal display during posed smile: contribution of soft tissue and underlying hard tissue.

The amount of upper incisor display (UID) during smile and conversation is one of the most decisive components in aesthetic judgment. The purpose of this study was to find which soft tissue and underlying hard tissue factors contributed to the amount of UID during posed smile (PS) and at rest posture (RP). The subjects consisted of 76 young adults (33 men and 43 women; mean [SD] age, 24.
