ABSTRACT
Background and Objectives@#Interposition using acellular allograft between perforated septal flaps is a popular procedure among surgeons because of its usefulness. However, allograft dermal matrix itself tends to become infected sometimes, and can easily undergo necrosis or be displaced from the implanted site. Here, the authors would like to introduce a newly devised interposition graft made up of allograft and cartilage, which is easy to manipulate and can be fixed in the desired position.Subjects and Method We performed a retrospective chart review from January 2018 to August 2020. A total of 12 patients with septal perforation who received surgical treatment were included in this study. Acellular human dermal allograft (MegaDerm® ; L&C Bio) was used as an interposition allograft piled up by autologous cartilage, and it was positioned between the mucoperichondrial flaps via the endonasal approach. @*Results@#The most common etiology was previous septal surgery (n=8); in one case, the etiology was repeated electrocauterization due to frequent epistaxis; the etiology was not verified for three cases. All 12 cases achieved the result of complete septal perforation closure. All patients on follow-up inquiry reported marked improvements in the visual analogue scale score (mean value, 4.1 to 1) and Nasal Obstruction Symptom Evaluation scale (mean value, 7.3 to 1.8). @*Conclusion@#Composite graft made up of cartilage and allograft dermal matrix achieved successful results without having to fix the graft. It can be an alternative technique to treat septal perforation for inexperienced surgeons and with a limited operation field.
ABSTRACT
Background and Objectives@#Measurement of sleep parameters in both supine and non-supine positions is important for the diagnosis of positional obstructive sleep apnea (OSA). However, the influence of right and left lateral decubitus positions (RLDP and LLDP, respectively) on sleep parameters is relatively unknown and has not been well investigated. This study was performed to verify the associations between sleep parameters and lateral decubitus sleep position. @*Methods@#A retrospective study was performed on 38 patients who were diagnosed with OSA and underwent surgical interventions from January 2014 to December 2016. Preoperative sleep parameters were evaluated with WatchPAT, and patients who slept sufficiently in both RLDP and LLDP to accurately analyze sleep parameters were enrolled in the study. Basic clinical data including body mass index (BMI) and nasal endoscopic findings of patients were assessed. @*Results@#The difference in peripheral arterial tonometry apnea-hypopnea index (pAHI) and PAT respiratory disturbance index (pRDI) between RLDP and LLDP showed no association with the side of deviated nasal septum. Patients with higher BMI showed higher pRDI in LLDP than RLDP (p=0.038). The difference in sleep position percentage between RLDP and LLDP was negatively correlated with the difference in pRDI (p=0.023). @*Conclusion@#Higher BMI patients with OSA might benefit more from sleeping in RLDP than LLDP. Patients slept longer in the lateral decubitus position that produced lower pRDI. Not only supine and non-supine positions, but also RLDP and LLDP need to be evaluated in patients with OSA.
ABSTRACT
Background@#Although long-term dopamine agonist (DA) therapy is recommended as a first-line treatment for prolactinoma, some patients may prefer surgical treatment because of the potential adverse effects of long-term medication, or the desire to become pregnant. This study aimed to determine whether surgical treatment of prolactinomas could be an alternative to DA therapy. @*Methods@#In this retrospective study, 96 consecutive patients (74 female, 22 male) underwent primary pituitary surgery without long-term DA treatment for prolactinomas at a single institution from 1990 to 2010. All patients underwent primary surgical treatment in the microscopic transsphenoidal approach (TSA). @*Results@#The median age and median follow-up period were 31 (16–73) years and 139.1 (12.2–319.6) months, respectively. An initial overall remission was accomplished in 47.9% (46 of 96 patients, 33 macroadenomas, and 13 microadenomas) of patients. DA dose reduction was achieved in all patients after TSA. A better remission rate was independently predicted by lower diagnostic prolactin levels and by a greater extent of surgical resection. Overall remission at the last follow-up was 33.3%, and the overall recurrence rate was 30.4%. The permanent complication rate was 3.1%, and there was no mortality. @*Conclusion@#TSA can be considered a safe and potentially curative treatment for selective microprolactinomas as an alternative to treatment with a long-term DA.
ABSTRACT
Background and Objectives@#Ranula is a type of pseudocyst caused by the leakage of saliva from the mouth floor, mainly the sublingual gland, and is classified into a simple ranula and a plunging ranula according to its location clinically. Currently known surgical treatment for ranula includes incision and drainage, marsupialization, ranula excision, and sublingual gland resection. The aim of this study was to help decision making for the treatment of ranula by analyzing the complications including the recurrence rate of each treatment.Subjects and Method We retrospectively reviewed 148 patients with ranula who had been treated from March 2000 to November 2019. All of the patients underwent one of the following treatments: incision and drainage, marsupialization, ranula excision, and sublingual gland resection. Complications including recurrence rate of each treatment were analyzed. @*Results@#Of 144 patients, 92 were simple ranula and 52 were plunging ranula. Four patients underwent incision and drainage, 24 patients with marsupialization, 12 patients with ranula excision, and 104 patients with sublingual gland resection. The recurrence rates according to the treatment of total ranula were 100%, 29.2%, 50.0%, and 8.7%, respectively, in the order of incision and drainage, marsupialization, ranula excision, and sublingual gland resection. There were no complications other than the recurrence of the ranula. @*Conclusion@#In the treatment of ranula, sublingual gland resection is considered to be the most appropriate method with minimal risk of complications and a low recurrence rate.
ABSTRACT
Background and Objectives@#Vocal process granulomas (VPGs) are benign lesions of the larynx, typically contact granulomas (CG) and intubation granulomas (IG). The two diseases are known to have different clinical manifestations despite having the same pathological features. The purpose of this study was to analyze the treatment results for CG and IG and to obtain clinical information.Materials and Method We retrospectively reviewed the medical records of patients diagnosed with VPG between January 2015 and December 2018. The patient’s age, sex, medical history, lesion size, lesion type, reflux finding score, response to treatment, duration of treatment, and follow-up period were compared. @*Results@#In total, 32 patients were included in the study, of which 18 were CG and 14 were IG. In the CG group, males were dominant (n=15, 83.3%), whereas in the IG group, females were dominant (n=11, 78.6%) (p=0.0009). The response to medical treatment using proton pump inhibitor and steroid inhaler was better in the IG group (11/14, 78.6%) than in the CG group (7/18, 38.9%) (p=0.036). Of the 14 patients who did not respond to medical treatment, 5 received botulium toxin injections, and all 5 had complete remission. The duration of medical treatment was significantly longer in the IG group (p=0.0029). @*Conclusion@#IG was more common in female, and CG was more dominant in male. IG had better response to medical treatment using proton pump inhibitor and steroid inhaler than CG.
ABSTRACT
Background and Objectives@#Functional aphonia refers to in which by presenting whispering voice and almost producing very high-pitched tensed voices are produced. Voice therapy is the most effective treatment, but there is a lack of consensus for application of voice therapy. The purpose of this study was to examine the vocal characteristics of functional aphonia and the effect of voice therapy applied accordingly.Materials and Method From October 2019 to December 2020, 11 patients with functional aphonia were treated using voice therapy which was processing three stages such as vocal hygiene, trial therapy, and behavioral therapy. Of these, 7 patients who completed the voice evaluation before and after voice therapy was enrolled in this study. By retrospective chart review, clinical information such as sex, age, symptoms, duration, social and medical history, process of voice therapy, subjective and objective findings were analyzed. Voice parameters before and after voice therapy were compared. @*Results@#In GRBAS study, grade, rough, and asthenic, and in Consensus Auditory-Perceptual Evaluation of Voice, overall severity, roughness, pitch, and loudness were significantly improved after voice therapy. In Voice handicap index, all of the scores of total and sub-categories were significantly decreased. In objective voice analysis, jitter, cepstral peak prominence, and maximum phonation time were significantly improved. @*Conclusion@#The voice therapy was effective for the treatment of functional aphonia by restoring patient’s vocalization and improving voice quality, pitch and loudness.

ABSTRACT
Osteogenesis imperfecta is a heterogeneous group of connective tissue diseases that is predominantly characterized by bone fragility and skeletal deformity. Two siblings with undiagnosed type I osteogenesis imperfecta underwent orthognathic surgery for the treatment of facial asymmetry and mandibular prognathism. The authors report two cases of combined orthodontics and orthognathic surgery in patients with type I osteogenesis imperfecta, mandibular prognathism, and facial asymmetry.
ABSTRACT
Granular cell tumor is rare tumor origination from Schwann cell. It occurs extremely rarely in pediatric age. Treatment is complete resection, but this may not always be possible because of the risk of airway stenosis or vocal cord paralysis. Six year-old male patient visited otolaryngology clinic due to dyspnea and stridor. Posterior glottis mass was indentified and was partially resected to confirm histology and resolve airway obstruction. One year after operation, the patient was living well without re-growing of tumor. We report a case of granular cell tumor in pediatric larynx with a review of literature.
ABSTRACT
The infratemporal fossa consists of critical structures affecting patient quality of life. Though abscess formation in the infratemporal fossa is very rare, drainage is highly recommended to avoid severe complications. We recently experienced a rare case of infratemporal fossa abscess. Such an abscess is easy to misdiagnose due to its rarity. Endoscopic drainage of the infratemporal fossa was conducted in this case, and its limited invasiveness was an advantage for a conservative approach. We present this case with a brief review of the approach to abscess of the infratemporal fossa area.
ABSTRACT
Objectives@#. This study aimed to elucidate the patterns of upper airway collapse in obstructive sleep apnea (OSA) patients with a low body mass index (BMI). @*Methods@#. We designed and conducted a retrospective cohort study. Consecutive patients diagnosed with OSA who underwent drug-induced sleep endoscopy (DISE) were included. Patients were classified into four groups according to their BMI. Age, sex, and polysomnography data were investigated. The patterns of upper airway collapse were characterized by the structures involved (soft palate, tongue base, lateral pharyngeal wall, and epiglottis). We compared the patterns of upper airway collapse in the supine and lateral decubitus position among the four BMI groups using the chi-square test and multivariate binary logistic regression analysis. @*Results@#. A total of 627 patients (male, 517; mean age, 47.6±12.8 years) were included, consisting of 45, 79, 151, and 352 patients who were underweight or lower normal-weight (defined as the low BMI group), upper normal-weight, overweight, and obese, respectively. Severity indicators of OSA, such as the overall apnea-hypopnea index and duration of SaO2 below 90%, were significantly lower in patients with a low BMI than in obese patients, while their average oxygen saturation was significantly higher. The most common obstruction site in the supine position was the tongue base in patients with a low BMI (100%), whereas this obstruction site was significantly less common in obese patients (54.8%). Tongue base obstruction was mostly relieved in the lateral position, with no discernible obstruction in 86.7% of the low BMI patients. @*Conclusion@#. Airway obstruction in OSA patients with a low BMI is mostly due to tongue base obstruction, which improves in the lateral position. These characteristics should be kept in mind when considering treatment options for this subgroup of OSA patients.

Lipoma is the most common benign neoplasm in adults. While it is commonly found in the neck, trunk, and extremities, it is extremely rare in the nasal cavity, paranasal sinus, or nasal septum. To our knowledge, there have been only a few cases of septal lipomas reported in the English literature. A 32-year-old woman visited Kosin University Hospital complaining of left nasal congestion and throat discomfort. Upon nasal endoscopy examination and CT, we found a polypoid mass of 2.7×1.5 cm with an elongated neck occupying a region left of the nasopharyngeal to the oropharyngeal cavity. The mass was completely removed via endoscopic endonasal surgery under general anesthesia and was identified as a fibrolipoma in the histopathological examination. We report a case of a successfully treated fibrolipoma originating from the posterior margin of the nasal septum.

Necrobiotic xanthogranulomatous reaction is a multiorgan, non-Langerhans cell histiocytosis with an unknown etiology. Occurrence in the salivary gland is extremely rare. We recently identified a case of necrobiotic xanthogranulomatous sialadenitis in a 73-year-old Korean woman who presented with a painless palpable lesion in the chin. There was no accompanying cutaneous lesion. Partial resection and subsequent wide excision with neck dissection were performed. Pathological examination showed a severe inflammatory lesion that included foamy macrophages centrally admixed with neutrophils, eosinophils, lymphocytes, plasma cells, and scattered giant cells, as well as necrobiosis. During the 12-month postoperative period, no grossly remarkable change in size was noted. Necrobiotic xanthogranulomatous inflammation may be preceded by or combined with hematologic malignancy. Although rare, clinicians and radiologists should be aware that an adhesive necrobiotic xanthogranuloma in the salivary gland may present with a mass-like lesion. Further evaluation for hematologic disease and close follow-up are needed when a pathologic diagnosis is made.

OBJECTIVES: There is a great deal of interest in the possibility that environmental factors may influence the risk of developing allergic rhinitis (AR) in early life. We investigated the simultaneous effects of mode of delivery and duration of breastfeeding on the development of AR in children. METHODS: Data from 1,374 children participating in the Allergic Rhinitis Cohort Study for kids (ARCO-kids study) was analyzed. All subjects were divided into AR or non-allergic rhinitis (NAR) groups. Data on environmental factors, mode of delivery and duration of breastfeeding were collected using a questionnaire. RESULTS: Compared with short-term breastfeeding (<6 months), long-term breastfeeding (≥12 months) was significantly associated with a lower prevalence of AR (adjusted odds ratio [aOR], 0.54; 95% confidence interval [CI], 0.34 to 0.88). Children in the AR group also had a higher cesarean delivery rate than those in the NAR group (39.1% vs. 32.8%, P=0.05). Regarding the combined effects of mode of delivery and duration of breastfeeding, long-term breastfeeding with a vaginal delivery strongly suppressed the development of AR, compared to short-term breastfeeding with a cesarean delivery (aOR, 0.47; 95% CI, 0.30 to 0.73). CONCLUSION: Long-term breastfeeding (≥12 months) and a vaginal delivery are associated with a lower risk of developing childhood AR.

PURPOSE: An enhanced recovery after surgery (ERAS) protocol incorporates up-to-date perioperative care principles; the primary aim in using an ERAS protocol is to reduce issues that delay the recovery and cause the complications. The aim of this study was to compare outcomes associated with head and neck cancer surgery with free-flap reconstruction before and after implementation of an ERAS protocol. METHODS: Outcomes were analyzed by dividing patients into 2 groups: 29 patients in the non-ERAS group and 60 patients in the ERAS group. The ERAS group performed a prospective observational cohort study of patients who underwent a head and neck cancer surgery with free-flap reconstruction in Ajou University Hospital from August 2015 to December 2017. The non-ERAS group retrospectively reviewed the medical records of patients who had undergone the same surgery from August 2012 to July 2015. RESULTS: Demographics, comorbidities, hospital length of stay (LOS), postoperative complications, starting time of rehabilitation, and postoperative periods before radiotherapy for the non-ERAS and ERAS groups were compared. Hospital LOS was significantly lower for patients whose care followed the ERAS protocol than for patients in the non-ERAS group (30.87 ± 20.72 days vs. 59.66 ± 40.43 days, P < 0.0001). CONCLUSION: In this study, hospital LOS was reduced through fast recovery after the implementation of the ERAS protocol. Therefore, the ERAS protocol appeared feasible and safe in head and neck cancer surgery with free-flap reconstruction.

PURPOSE: Whereas the majority of nasal polyps observed in Western populations are eosinophilic, non-eosinophilic nasal polyps are significantly more frequent in Asian countries. Given the importance of nuclear factor-kappa B (NF-κB) in inflammation, this study focused on the role of NF-κB in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNPs) in Asian patients. METHODS: A total of 46 patients were enrolled in this study (22 diagnosed with CRSwNPs, 10 with chronic rhinosinusitis without nasal polyps [CRSsNP], and 14 control subjects). Nasal polyps and uncinate tissues (UTs) were collected and the tissues prepared for hematoxylin-eosin staining and immunohistochemistric (IHC) analysis. Total RNA was isolated for real-time polymerase chain reaction for p65, interleukin (IL)-6, IL-8, intracellular adhesion molecule (ICAM)-1, IL-1β, tumor necrosis factor (TNF)-α, and eotaxin. RESULTS: In the CRSwNPs group, 50% of nasal polyps were non-eosinophilic. IHC revealed a significantly higher fraction of NF-κB p65-positive cells in nasal polyps of the CRSwNPs group than in the UTs of control and CRSsNP groups. No difference in NF-κB p65-positive cell fraction was observed between eosinophilic and non-eosinophilic nasal polyps. The mRNA expression of p65, IL-6, IL-8, and eotaxin was significantly higher in nasal polyps of the CRSwNPs than in the UTs of control and CRSsNP group. However, no difference in expression was observed between eosinophilic and non-eosinophilic nasal polyps, with the exception of IL-1β expression. CONCLUSIONS: Elevated expression of NF-κB- and NF-κB-associated inflammatory cytokines suggests NF-κB as the key factor for CRSwNPs pathogenesis in Asian patients. Understanding NF-κB-associated mechanisms will provide a deeper insight into CRSwNPs pathogenesis and ultimately improve therapeutic strategies for CRSwNPs.
