Velopharyngeal insufficiency (VPI) is a phenomenon that can occur due to anatomical or neurological causes of the soft palate. VPI can make the patient difficult to articulate through hypernasality and nasal emission. There has been needed the customized treatment, as VPI can occur for many causes. We present the case of 21-year-old male who took palate plastic surgery 20 years ago for congenital submucosal cleft palate. As he had poor contraction of both lateral side of velopharynx, he was diagnosed with coronal type VPI. Through sphincter pharyngoplasty, he can obtain improvement of articulation accuracy. We would like to share this challenged case.

Objectives The purpose of this study is to find the cephalometric variables which are significantly correlated with the apnea-hypopnea index (AHI) in suspected Korean obstructive sleep apnea (OSA) patients. Methods We examined lateral cephalogram and attended-full night laboratory polysomnography of the 40 participants who complained of OSA symptoms. The correlation analysis was conducted to find the cephalometric variables which are significantly correlated with the AHI. Results The correlation analysis showed that the higher AHI was associated with the longer distance between hyoid and mandibular plane (p = 0.023), the longer distance between C3 and hyoid (p = 0.014), the longer tongue length (p = 0.003), the larger inferior tongue area (p = 0.008), the larger anterior displacement of the hyoid bone (p = 0.024), the longer distance between posterior nasal spine and the tip of the soft palate (p = 0.021), and the larger cross-sectional area of soft palate (p = 0.001) of cephalogram in erect position. The higher AHI was correlated with the longer distance between hyoid and mandibular plane (p = 0.008), the longer tongue length (p = 0.037), the larger inferior tongue area (p = 0.013), the thicker uvula (p = 0.004), the longer distance between retrognathion and hyoid (p = 0.025), and larger cross-sectional area of soft palate (p = 0.001) of cephalogram in supine position. Conclusions The present preliminary results showed the candidate measurements of cephalogram which are significantly correlated with the AHI in suspected OSA.

Snorer와 정상인의 상기도 부위 연조직의 차이를 비교하며, 자세의 변화에 따른 snorer와 정상인의 상기도 부위 연조직 크기의 변화를 알아보고자 여성에서 snorer군 25명과 정상군 20명을 대상으로 직립위와 앙와위에서 측모 두부방사선 계측 사진을 촬영한 후 연구개, 혀 및 상기도에 관한 거리와 면적을 계측하고 통계학적으로 분석하여 다음과 같은 곁과를 얻었다. 1. 직립위와 앙와위에서 snorer군은 정상군에 비해 혀의 길이가 길고 높이가 높았으며 기도가 좁고 길며 설골은 하방에 위치하였고 넓은 연구개와 좁은hypopharynx를 가졌다. 앙와위에서 snorer군은 이와 더불어 정상군보다 더 넓은 혀와 더 좁은 oropharynx를 가졌다. 2. 직립위에서 앙와위로 자세의 변화에 따라 정상군과 snorer군 모두에서 기도의 길이가 감소하였고 설골이 더 상방위치 되었다. snorer군에서는 이와 더불어 혀의 길이와 높이, 기도의 두께와 oropharynx 면적은 감소하였으며 혀와 연구개 면적은 증가하였다.

Orthodontic treatment of cleft patients is difficult as the growth is different from that of normal ones. So it is very important to know the characteristic features of the craniofacial morphology and growth pattern in unilateral cleft lip and palate patients. The materials for this study consisted of 55 normal males and 50 unilateral cleft lip and palate ones who received cheiloplasty and palatoplasty previously. The cleft subjects were divided into 4 groups according to their ages kto find out the growth pattern of hard and soft tissue, and to compare the features with those of normal ones. Each cephalogram analysed by McNamara method and others. The obtained results were as follows 1. In the unilateral cleft lip and palate subjects, forward growth of the maxilla was smaller than that of normal ones from 9 years old. So the maxilla was retruded. The maxillary incisors were severely retruded in all age groups. 2. The mandibular overall length and its anteroposterior position did not show any significant differences between two groups. But the height of ramus was very short and the mandible had vertical growth tendency to compensate for undergrowth of the maxilla in cleft subjects after 12 years of age. 3. Horizontal growth of the soft tissue in middle face was smaller than that of any other facial region from 9 years old. The vertical growth rate of upper lip was decreased as growing old. 4. In cleft subjects, the upper and lower facial component angle and the facial convexity angle were large. So their facial profile changed to straight or concave as growing old.

Authors experienced a case of intermediate grade mucoepidermoid carcinoma in 29-year-old female. The origin of this tumor might be mucus secreting cells of palatal mucous gland. The characteristic features were as follows: 1. In clinical examination, exopytic mass was observed in left hard palate and similar to pleomorphic adenoma. 2. In radiographic findings, destructive changes of left hard palate, nasal septum, nasal inferior turbinate and floor of maxillary sinus and soft tissue mass were observed. 3. Histopathologically, mucus-secreting cells, epidermoid cells and intermediate cells were observed and diagnosed as intermediate grade mucoepidermoid carcinoma.

Velopharyngeal function refers to the combined activity of the soft palate and pharynx in closing and opening the velopharyngeal port to the required degree. In normal speech, various muscles of palate & pharynx function as sphincter and occlude the oropharynx from the nasopharynx during the production of oral consonant sounds. Inadequate velopharyngeal function caused by neurologic disorder - cerebral apoplexy, regressive diseases - disseminated sclerosis, Parkinson's disease, congenital deformity - cleft palate, cerebral palsy and etc. may result in abnormal speech characterized by hypernasality, nasal emission and decreased intelligibility of speech due to weak consonant production. In our study, we constructed speech aids prosthesis - Palatal lift in acquired idiophathic VPI patient and assessed velopharyngeal function with various diagnostic instruments which can evaluate the speech characteristics objectively.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

The soft tissue triangle is an easily recognizable subunit of the nose. Therefore, deformities in this region resulting from trauma or complications after cosmetic surgery can have serious cosmetic impacts. Various reconstruction choices exist for deformities such as depression of the soft triangle but choosing the most appropriate treatment in each case remains a challenge. In the case described herein, a patient underwent augmentation rhinoplasty with a silastic implant and experienced implant exposure in the soft triangle area. After implant removal, the patient complained of depression in this area. The authors effectively solved this problem through a de-epithelialized composite tissue graft. In this report, we present this case and review similar cases of reconstruction of the soft triangle.

구순 구개열은 구강 악안면 부위에 발생하는 선천적 기형이다. 정상적인 연구개는 휴식 시에는 구강과 비강을 연결해 주고, 연하나 특정 발음 시에는 상방으로 이동하여, 구강과 비강을 분리하는 구개인두 폐쇄 운동을 한다. 구개인두 기능부전을 갖는 구개열 환자에서는 이 운동이 불완전하여 저작, 연하, 발음 시에 어려움을 겪는다. 이때, 구개 결손부를 폐쇄하기 위해 사용하는 보철물을 구개 폐쇄장치라고 한다. 구개 폐쇄장치는 구강과 비강을 분리하여 발음, 저작, 연하, 심미적 기능을 회복한다. 본 증례의 환자는 구개인두 기능부전을 갖는 선천적 구개열 환자로 구개인두 폐쇄를 이루기 위하여 모델링 콤파운드와 점막 조정재를 이용한 기능인상 과정을 시행하여 제작한 구개 폐쇄장치를 장착하여 기능적인 면과 심미적인 면에서 만족할만한 결과를 얻었기에 이를 보고하는 바이다.

Purpose: In rare cases, infectious disease can become the cause of palatal fistula as it usually occurs in immunocompromised patients. We are reporting this case because we have successfully reconstructed palatal fistula occurring due to infectious disease in a healthy adult. Methods: A 62-year-old female patient had visited our hospital with a palatal hole that had occurred after suffering from a severe febrile disease. An oro-nasal fistula measuring $1.5{\times}1.3cm$ has been observed in the junction of the soft palate and hard palate, and is presumed to be caused by an infectious disease according to the patient's history. It was reconstructed using a hinge flap and a mucoperiosteal flap. Results: For 6 months, no recurrence or complications had been observed. The post operative patient was satisfied with the improvement in nasal speech and fluid regurgitation. Conclusion: We reported this case since we had obtained a functionally satisfactory result by reconstructing the palatal fistula due to infectious disease in a healthy adult.
