Nasal obstruction may cause or aggravate sleep disordered breathing but exact pathogenesis is not clear. The possible mechanism could be combination of alteration in upper airway aerodynaimcs, loss of nasal reflex or sensation, effect of mouth opening, and a genetic predisposition. Anatomical narrowing of nasal airway cause more rapid airflow and induce more negative inspiratory air pressure. So, it increases collapsibility of pharyngeal airway. Loss of nasal sensation to airflow block nasal reflex. Mouth opening decreases the activity of pharyngeal airway dilator muscles and narrowing the pharyngeal airway may occur. The treatment of nasal obstruction should be done according to the cause. The causes of nasal obstruction are various from problems of external nasal opening to nasopharynx. Relief of nasal obstruction may not cure sleep disordered breathing always. In some mild obstructive sleep apnea patients, treatment of nasal obstruction only may cure sleep disordered breathing. In some severe sleep apnea patients, treatment of nasal obstruction may increase compliance of continous nasal positive airway pressure.

Cystic metastasis in the neck from pharyngeal cancer has often been mistaken for either primary squamous cell carcinoma of branchiogenic origin or branchial cleft cyst. The distinctive histological and clinical features of cystic metastasis reviewed after its correct indentification can lead to the discovery of an unsuspected primary lesion and result in specific treatment options. Recendy, the authors experienced three cases of cystic metastasis in the neck from pharyngeal cancer ; one was from nasopharyngeal squamous cell carcinoma and the other two were from tonsillar squamous cell carcinomas. This report summarizes our experiences and review of the literatures.

양악 수술 시 상악골의 상방이동을 시행하였을 경우에 상기도의 공간적 구조변화를 평가하기 위하여, 술전, 술후, 술후 6개월 후의 간격으로 두부규격방사선사진을 촬영하여 그 변화량을 분석해 보았다. 술전 교정치료를 시행하여 상악은 Le Fort I 골절단술로 상방이동 시행하였고 동시에 하악은 후방이동 시키는 수술을 시행 받은 24명을 대상으로 하였다 (평균 연령22세 1개월, 남자 9명 여자 15명). 상악골 상방이동에 대한 상기도 공간의 변화와 그에 따른 관련성을 조사한 결과, PAS (R)부위는 술후 (T1) 감소하였으나 (p<0.01) 술후 6개월 후(T2)에는 다시 증가하여 술전과 비교 시, 크기 변화를 관찰할 수 없었고, PAS (NL) 부위는 술후(T1)와 술후 6개월 후(T2)에서 유의성 있는 크기 증가를 보였다. PAS (OL)의 경우, 술후 (T1)증가를 보이다가 술후 6개월 이후(T2)에서 감소하였다. 연구개의 두께는 술후 (T1) 증가를 보이다가 6개월 이후 (T2) 처음과 같거나 약간 감소하는 것으로 나타났으며 FH-uvular 각도는 술후 6개월 이후 증가하였다. 또한 상악골 상방이동에 대한 상기도 공간의 변화를 회귀분석 시행한 결과 양악수술 시 평균 $4.40{\pm}1.14mm$의 상악골 상방이동은 양악 수술 후 상기도 공간의 변화에 큰 영향을 미치지 않는 것으로 나타났다.

Despite the incidence of tuberculosis has been greatly reduced with chemotherpy, it is still a common disease in Korea. The pharyngeal and laryngeal tuberculosis usually result from direct contamination of the laryngeal or pharyngeal mucosa by sputum heavily laden with Mycobacterium tuberculosis, secondary infection from the lungs via lymphatic or hematogenous routes, or a primary affection from inhaled tubercle bacilli. Recently the authors experienced a pharyngolaryngeal tuberculosis and report this case with brief literatures review.

A female child with unilateral midpalatal cleft was successfully treated by Wardill V-Y pushback palatal flap and superiorly based pharyngeal flap simultaneously. The advantages of this method are to prepare the favorable background of postoperative speech correction and additional nasal lining. We can try this simultaneous operation in delayed cleft palate repair.

묵납자루에서 첫 번째 새궁 (gill arch)의 새파 수는 17-21개 (평균 19개) 정도로 적은 편이었으며, 새파의 길이는 280~430 (평균 $360{\pm}35)mm$이었다. 새파 간의 간격은 130~210 (평균 $160{\pm}15)mm$이었다. 인두치의 저작면은 안쪽이 파여 있는 형태로 제1치는 저작면의 발달이 매우 미약하나 제2, 3, 4, 5치의 저작면은 발달되어 있었다. 인두치와 새파는 생활사의 초기에 완전히 형성되었다. 소화관의 길이는 체장의 $3.63{\pm}0.12$배로 매우 길었으며, 식도에서 연결되어 항문쪽으로 길게 배열되다가 한번 접히고 시계방향으로 5회 정도 감긴 후 항문으로 연결되어 있었다. 묵납자루는 주로 식물성플랑크톤의 일종인 부착조류를 주로 섭식하였으며 그 중 규조류의 비율이 가장 높았고, 그 이외에 원생동물, 깔따구 유충, 식물의 씨앗, 육상곤충 등도 소화관 내용물에서 관찰되어 초식성이 강한 잡식성으로 볼 수 있었다.

Introduction: To evaluate the 3-dimensional changes in the pharyngeal airway of skeletal class III patients after bimaxillary surgery. Materials and Methods: The study sample consisted of 18 Korean patients that had undergone maxillary setback or posterosuperior movement and mandibular bilateral sagittal split osteotomy setback surgery due to skeletal class III malocclusion (8 males, 10 females; mean age of 28.7). Cone beam computed tomography was taken 1 month before and 6 months after orthognathic surgery. Preoperative and postoperative volumes of the nasopharyngeal, oropharyngeal, and laryngopharyngeal airways and minimum axial areas of the oropharyngeal and laryngopharyngeal spaces were measured. Moreover, the pharyngeal airway volume of the patient group that had received genioplasty advancement was compared with the other group that had not. Results: The nasopharyngeal and laryngopharyngeal spaces did not show significant differences before or after surgery. However, the oropharyngeal space volume and total volume of pharyngeal airway decreased significantly (P<0.05). The minimum axial area of the oropharynx also decreased significantly. Conclusion: The results indicate that bimaxillary surgery decreased the volume and the minimum axial area of the oropharyngeal space. Advanced genioplasty did not seem to have a significant effect on the volumes of the oropharyngeal and laryngopharyngeal spaces.

Background: Israeli Arabs are considered as a developing society characterized by poverty and high levels of smoking among men. The purpose of this study was to describe their incidence, mortality and survival rates for oral and pharyngeal cancer between the years 1970-2006. Studies such as this in the Arab world, where the population is almost the same as the Arab population in Israel, are rare. Methods: The incidence and survival data were derived from all relevant registered data at the National Cancer Registry. The group of lesions included cancer of the lips, tongue, buccal mucosa, floor of the mouth, salivary glands, gums, palate and pharynx. Morphological description was according to WHO classification. Results: Most diagnosed patients were male. The mean age was 54.4 years, and mean years of survival were 3.83. The oropharynx was the most common site (28.3%) while the palate was the least frequent (3.12%). Squamous cell carcinoma (SCC) was the most common histological feature (66.3%), while basal cell carcinoma (BCC) was the least (3.9%). The overall 5 years survival rate was 59.4%, this being highest for BCC (82.1%), while SCC was significantly lower (56.2%) (p<0.001). Lip cancers survived better than other sites. Conclusions: Data from this society are similar to other developing societies in the majority of the results. The incidence of oral and pharyngeal cancer is lower among the Arab population, in comparison to the Jewish population in Israel.

Background: This study investigated the outcomes of pharyngeal flap surgery in Asian patients with velopharyngeal dysfunction (VPD), with a focus on postoperative improvements in speech articulation and complications. Additionally, this study explored whether the cause of VPD and the timing of surgery affected outcomes in terms of speech improvement. Methods: A retrospective review was conducted of the medical records of 72 Asian VPD patients who underwent pharyngeal flap surgery performed by a single surgeon from 1996 to 2014. Operative complications were analyzed for all 72 patients, and preoperative and postoperative speech articulation tests were compared for the subset of 43 patients in whom such testing was possible. The relationships of age at surgery and the cause of VPD with the extent of improvement in speech articulation were also investigated. Results: Nine of the 72 patients (13%) experienced wound-related complications. Furthermore, 34 patients (47%) reported persistent snoring lasting for over 3 months, and 16 (22%) reported snoring for over 1 year. Three patients (4%) underwent reoperation. Speech articulation scores significantly improved postoperatively across all groups. Younger age at surgery was associated with greater improvements in speech outcomes, but no significant relationship was found between the cause of VPD and the extent of the postoperative improvement in speech outcomes. Conclusion: Speech outcomes improved after pharyngeal surgery in Asian patients with VPD. Early surgery was associated with favorable speech outcomes, but no association was found between the cause of VPD and postoperative speech outcomes.
