Background Reconstruction after removal of a malignant tumor in the head and neck region is crucial for restoring tissue integrity, function, and aesthetics. We retrospectively analyzed patients who underwent intraoral reconstruction surgery using radial forearm free flaps (RFFF) and anterolateral thigh free flaps (ALT) at a single institution to provide more information supporting the choice of a reconstruction method after removal of head and neck cancer. Methods The charts of 708 patients who underwent head and neck reconstruction between 1998 and 2018 at the Department of Plastic and Reconstructive Surgery at our institution were retrospectively reviewed. Patients' age, sex, and history of radiation therapy, diabetes mellitus, and smoking were retrieved. The primary cancer site, types of defects, and complications were investigated. Results Overall, 473 and 95 patients underwent reconstruction surgery with RFFF and ALT, respectively. RFFF was more often used in patients with cancers of the pharynx, larynx, esophagus, or tonsil, while ALT was more frequently used in patients with cancers of the mouth floor with tonsil or tongue involvement. The proportion of patients undergoing ALT increased gradually. Flap failure and donor site morbidities did not show significant differences between the two groups. Conclusions RFFF and ALT flaps resulted in similar outcomes in terms of flap survival and donor site morbidity. ALT can be an option for head and neck reconstruction surgery in patients with large and complex defects or for young patients who want to hide their donor site scars.

The aim of this paper is to describe the linguistic differences of two Koreas with a special emphasis on the phonetic aspect of Seoul and Pyongyang speech. The sources of the North Korean speech material used in the study are 1) the Pyongyang radio and TV broadcasts, 2) interviews of north Korean defectors and 3) speech material of north Korean scholars collected by the writer in london, Warsaw, France and China between 1989 and 1994. The most noticeable phonetic differences of Seoul and Pyongyang speech are abstracted as follows: 1) The vowels /이/, /에/ and /애/ are higher and fronter in Pyongyang speech than in Seoul speech. 2) The vowels /우/ and /으/ of Pyongyang speech are somewhat fronter than the corresponding vowels of Seoul speech. 3) The Pyongyang vowels /으/ and if are produced with rounded lips compared to the corresponding Seoul vowels. 4) The Pyongyang vowel /h) is much lower in tongue position and at the same time somewhat fronter than the corresponding Seoul vowel. 5) The consonants /r ,i ,n / are pronounced in Pyongyang as alveolar affricates or something close to them whereas they are pronounced in Seoul as post-alveolar affricates. 6) Unlike in Seoul speech there is a very strong tendency in Pyongyang speech to reduce aspiration feature in consonant seouences such as /ㅂ+ㅎ/, /ㄷ+ㅎ/, /ㄱ+ㅎ/. 7) /ㄴ/ and /ㄹ/(flap) freely occur word-initially in Pyongyang speech whereas they are restricted in Seoul speech. 8) Unlike in Seoul speech the phonemic contrast of long and short vowels are generally not functional in Pyongyang speech. Thus the vowels pronounced long in Seoul speech are usually pronounced short in Pyongyang speech.

The purpose of this study is to describe the clinical availability of a variety of intraoral local flaps in reconstruction of oral soft tissue defects, Forty patients with oral soft tissue defects were treated by tongue, buccinator, palatal, labial, facial artery musculomucosal, buccal fat pad, and masseter muscle crossover flap. Total 43 intraoral flaps were used to reconstruct a variety of intraoral soft tissue defects, such as oronasal fistula, oroantral fistula, traumatic deformities and other. The age of patients ranged from 7 to 72 years, with mean age of 39.6 years. Follow up period ranged from 2 to 66 months, mean follow up period of 21.6 months. There were 9 complications, of which four were partial necrosis, three infections, one total necrosis, and 1 speech problem. Except for total necrosis, most of the recipient sited healed uneventually without severe morbidity. We consider that a variety of intraoral local flaps can be available for reconstruction of small of moderate large intraoral soft tissue defects.

Background: The paradigm of tonsillectomy has shifted from a treatment of recurrent throat infection to one of multi-discipline management modalities of sleep-disordered breathing (SDB). While tonsillectomy as a treatment for throat problems has been performed almost exclusively by otorhinolaryngologists, tonsillectomy as a part of the armamentarium for the multifactorial, multidisciplinary therapy of sleep-disordered breathing needs a new introduction to those involved in treating SDB patients. This study has its purpose in sharing a series of tonsillectomies performed at the Seoul National University Dental Hospital for the treatment and prevention of SDB in adult patients. Methods: Total of 78 patients underwent tonsillectomy at the Seoul National University Dental Hospital from 1996 to 2015, and 23 of them who were operated by a single surgeon (Prof. Jin-Young Choi) were included in the study. Through retrospective chart review, the purpose of tonsillectomy, concomitant procedures, grade of tonsillar hypertrophy, surgical outcome, and complications were evaluated. Results: Twenty-one patients diagnosed with SDB received multiple surgical procedures (uvulopalatal flap, uvulopalatopharyngoplasty, genioglossus advancement genioplasty, tongue base reduction, etc.) along with tonsillectomy. Two patients received mandibular setback orthognathic surgery with concomitant tonsillectomy in anticipation of postoperative airway compromise. All patients showed improvement in symptoms such as snoring and apneic events during sleep. Conclusions: When only throat infections were considered, tonsillectomy was a procedure rather unfamiliar to oral and maxillofacial surgeons. With a shift of primary indication from recurrent throat infections to SDB and emerging technological and procedural breakthroughs, simpler and safer tonsillectomy has become a major tool in the multidisciplinary treatment modality for SDB.

A flathead fish, collected from the water off Cheju lsland is tentatively identified as Inegocia guttata of the family Platycephalidae for the first time from Korea. Inegocia guttata is similar to Cymbacephalus beauforti in morphological characters, but differs from C. beauforti in lacking dermal flaps on eyes and having pored scales much fewer than oblique scales slanting backward and downward above the lateral line, single and tongue - like interopecular flap, nasal spines and circled blackish spots in the pectoral and ventral fins. A new Korean name, "Akoyangtae", is proposed for the I. guttata.

A calcifying epithelial odontogenic tumor (CEOT) was first described as a separate entity in 1955 by Pindborg, and has since been referred to as Pindborg tumor. CEOT is characterized by the presence of squamous-cell proliferation, calcification and amyloid deposits, and accounts for only 1% of all odontogenic tumors. CEOT is a benign, though occasional locally invasive, slow-growing neoplasm. It is located either intraosseously or extraosseously, and is usually associated with an unerupted permanent tooth. A 24 year-old female visited our clinic, presenting with a palatal swelling and intra-oral ulcer. After an incisional biopsy, the lesion was confirmed to be odontogenic tumor. A tumor resection and reconstruction surgery with tongue flap were performed.
