Combination Biologic Therapy with Mepolizumab and Dupilumab for Severe Eosinophilic Granulomatosis with Polyangiitis and Chronic Rhinosinusitis with Nasal Polyp.

We report the case of a 55-year-old female with eosinophilic granulomatosis with polyangiitis and chronic rhinosinusitis with nasal polyp. Rhinosinusitis recurred 6 months after full-house endoscopic sinus surgery. Although conventional treatment with azathioprine and mepolizumab with steroids was given, it was difficult to simultaneously control both rhinosinusitis and eosinophilic granulomatosis with polyangiitis. Clinical examinations showed polyps in the olfactory cleft, and the patient's anosmia gradually became persistent. Even after administering mepolizumab for a certain period of time, symptoms did not improve, but when the biologic agent was switched to dupilumab, an improvement in recalcitrant chronic rhinosinusitis with nasal polyp was observed. While dupilumab was administered intermittently for refractory chronic rhinosinusitis with nasal polyp, the rhinosinusitis improved and symptoms such as worsening of eosinophilic granulomatosis with polyangiitis paresthesia were observed. Both symptoms gradually subsided 19 months after starting intermittent administration, leading to the discontinuation of dupilumab administration. Rhinosinusitis in the setting of eosinophilic granulomatosis with polyangiitis may be refractory in some cases, and this case provides findings demonstrating the strong effect of dupilumab on eosinophilic inflammation.

Acceptability, Safety, and Feasibility of Transnasal and Peroral Ultrathin Endoscopy Using GAGLESS Mouthpieces: A Prospective Randomized Trial.

BACKGROUND/AIM: Esophagogastroduodenoscopy (EGD) is an effective screening method for early detection of gastric cancer. The GAGLESS mouthpiece has a structure that widens the pharyngeal cavity and suppresses the pharyngeal reflex. This study aimed to investigate the acceptability, safety, and feasibility of transnasal and peroral ultrathin endoscopy using GAGLESS mouthpieces (Clinical Trial Number: UMIN000036922). PATIENTS AND METHODS: This study was a multicenter, prospective, randomized, open-label trial performed using a questionnaire. The study included 101 consecutive patients who visited the participating medical institutions between June 2019 and March 2022 (median age=47 years, range=24-87 years; all male). Patients aged ≥20 years at the time of consent acquisition who were the first to undergo EGD were included in the study. The primary endpoint was the degree of distress during EGD, as determined using a visual analog scale (VAS). RESULTS: The VAS score during endoscopic passage through the pharynx was significantly better in the transnasal endoscopy group than in the oral endoscopy group (2.420 vs. 4.092, p=0.001). There was no significant difference in the VAS scores between the two groups during anesthesia or throughout the examination. Compared with nasal endoscopy, oral endoscopy with a GAGLESS mouthpiece did not reduce the VAS score but did significantly improve gastric visibility. CONCLUSION: For patients in whom there was difficulty in inserting a nasal endoscope, using a GAGLESS mouthpiece rather than a conventional mouthpiece may be more useful in reducing pain.

In Vivo Measurement of Ear Ossicle and Bony Wall Vibration by Sound Stimulation of Cartilage Conduction.

The cartilage-conduction pathway was recently proposed as a third auditory pathway; however, middle-ear vibrations have not yet been investigated in vivo. We aimed to measure the ossicles and bone vibration upon cartilage-conduction stimulation with a non-contact laser Doppler vibrometer. We recruited adult patients with normal ear structures who underwent cochlear implant surgery at our hospital between April 2020 and December 2022. For sound input, a cartilage-conduction transducer, custom-made by RION Corporation (Tokyo, Japan), was fixed to the surface of the tragus and connected to an audiometer to regulate the output. A posterior tympanotomy was performed and a laser beam was directed through the cavity to measure the vibration of the ossicles, cochlear promontory, and posterior wall of the external auditory canal. Five participants (three men, mean age: 56.4 years) were included. The mean hearing loss on the operative side was 96.3 dB HL in one patient, and that of the other patients was off-scale. The vibrations were measured at a sound input of 1 kHz and 60 dB. We observed vibrations of all three structures, demonstrating the existence of cartilage-conduction pathways in vivo. These results may help uncover the mechanisms of the cartilage-conduction pathway in the future.

Factors Associated with Complications after Total Pharyngo-Laryngo-Esophagectomy and Free Jejunal Flap Reconstruction.

INTRODUCTION: Free jejunal flap (FJF) reconstruction is a standard procedure for pharyngeal and cervical esophageal defects resulting from head and neck cancer resection. However, improvements in patients' quality of life after surgery require a further statistical approach. METHODS: An observational, retrospective, multivariate analysis was designed to report the incidence of postoperative complications and their association with clinical factors in 101 patients who underwent total pharyngo-laryngo-esophagectomy and FJF reconstruction for head and neck cancer at a university hospital between January 2007 and December 2020. RESULTS: Postoperative complications were observed in 69% of patients. In the reconstructive site, anastomotic leak, observed in 8% of patients was associated with vascular anastomosis in the external jugular vein system (age-adjusted odds ratio [OR]: 9.05, p = 0.044) and anastomotic stricture, observed in 11% of patients was associated with postoperative radiotherapy (age-adjusted OR: 12.60, p = 0.02). Cervical skin flap necrosis was the most common complication (34%) and was associated with vascular anastomosis on the right cervical side (age- and sex-adjusted OR: 4.00, p = 0.005). CONCLUSION: Although FJF reconstruction is a useful procedure, 69% of patients suffer a postoperative complication. We suppose that anastomotic leak is related to the low blood flow resistance of the FJF and inadequate drainage of the external jugular venous system, and anastomotic stricture is related to the vulnerability of the intestinal tissue to radiation. Furthermore, we hypothesized that the location of the vascular anastomosis may affect the mesenteric location of the FJF and the dead space in the neck, leading to the development of cervical skin flap necrosis. These data contribute to increasing our knowledge about postoperative complications related to FJF reconstruction.

Reconstruction for Bilateral Internal Jugular Vein Perfusion Disruption.

When resecting the internal jugular veins bilaterally in surgery for head and neck cancer, it is necessary to perform neck dissection in two stages or to reconstruct the internal jugular veins in one stage. Reconstruction of the internal jugular vein using grafting or direct anastomosis to the external jugular vein have both been reported. We report the case of a 53-year-old man with accidental injury to the left internal jugular vein after resection of the right internal jugular vein for supraglottic cancer. The left internal jugular vein was damaged near the inflow of the subclavian vein, making vein grafting difficult. Therefore, internal jugular venous return was reestablished by end-to-side anastomosis of the left internal jugular vein to the left external jugular vein system. In this surgical procedure, by incising the internal jugular vein obliquely, it was not necessary to match the calibers of the internal jugular vein and the external jugular vein system, and a smooth hemodynamic body was reconstructed. In addition, we were able to reconstruct the internal jugular vein while preserving blood flow in the external jugular vein system. End-to-side anastomosis of the internal jugular vein to the external jugular system is an option for internal jugular vein reconstruction.

Olanzapine for The Prevention of Nausea and Vomiting Caused by Chemoradiotherapy with High-Dose Cisplatin for Head and Neck Cancer.

Background: Chemotherapy-induced nausea and vomiting (CINV) are the most common and distressing adverse events in patients receiving anticancer therapy. Radiotherapy also induces nausea and vomiting, so concurrent chemoradiotherapy-induced nausea and vomiting (CRINV) are significant problems for patients undergoing chemoradiotherapy. Conventionally, three-drug combination therapy with dexamethasone, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist, and neurokinin-1 (NK1) receptor antagonist has been used to prevent CRINV induced by concurrent chemoradiotherapy with cisplatin for patients with head and neck cancer (HNC). Nonetheless, CRINV still remains a problem. The effectiveness of adding olanzapine to prevent CINV has been reported, suggesting the efficacy of four-drug combination therapy for CRINV. However, its effectiveness has hardly been reported in patient receiving chemoradiotherapy for HNC. Methods: A total of 109 patients with HNC who received concurrent chemoradiotherapy with cisplatin from April 2014 to March 2021 were included and divided into the following two groups according to antiemetic treatment regimen: the conventional group (Con group; n = 78) who received three-drug combination therapy and the olanzapine group (Olz group; Olz group, n = 31) who received four-drug combination therapy with olanzapine. Acute (0 to 24 h from cisplatin) and delayed (25 to 120 h from cisplatin) CRINV were then compared using the Common Terminology Criteria for Adverse Events. Results: No significant difference in acute CRINV were observed between both groups (P = 0.5761, Fisher's exact test). However, the Olz group had a significantly lower incidence rate of delayed CRINV over Grade 3 compared to the Con group (P = 0.0318, Fisher's exact test). Conclusion: Four-drug combination therapy with olanzapine was effective in suppressing delayed CRINV due to chemoradiotherapy with cisplatin for HNC.

[Transoral Robotic Surgery for Head and Neck Cancer].

Robotic surgery for head and neck cancer [transoral robotic surgery (TORS)] was covered by insurance in Japan in 2022. The number of hospitals performing this surgery is gradually increasing. The indications for TORS are Tis, T1, and T2, without extra nodal involvement of metastatic lymph nodes of oropharyngeal, hypopharyngeal, supraglottic carcinoma. In TORS, the important point is not only robotic manipulation technique, but also knowledge of pharyngeal inside-out anatomy, setting of retractor, docking of the robotic arm and instrument, and accurate evaluation of the extent of tumor invasion. The introduction of single-port robot might affect the expansion of surgical indications for TORS.

Serum periostin levels in adolescents.

BACKGROUND: The significance of periostin as a biomarker of Th2-induced airway inflammation has recently been highlighted in adult patients with allergic diseases. It may help identify drug-responsive inflammatory phenotypes, particularly in children. However, little is known about the usefulness of this parameter as a biomarker for allergic diseases in children. Furthermore, it is not known how much adolescent bone metabolism affects allergic inflammation. OBJECTIVE: To evaluate the relationship between serum periostin levels and allergic diseases in adolescents, we investigated periostin levels and the prevalence of allergic diseases. METHODS: We conducted a cross-sectional observational study of 100 males and females in two age groups: age 9-12 years (pre-early adolescence) and 13-15 years (post-early adolescence). Serum periostin levels were determined using Enzyme-Linked Immuno Sorbent Assay (ELISA). Presence of allergic diseases and allergy sensitization were obtained via a self-reported survey and the Multiple Antigen Simultaneous Test (MAST). The protocol was registered in a clinical trial registry as UMIN 000036051. RESULTS: There were no significant differences in serum periostin levels between pre-early and post-early adolescents. There were no differences by gender. Age and Body Mass Index were not significantly associated with serum periostin levels. Periostin levels were elevated in adolescents with allergic diseases overall compared to healthy adolescents [mean (95%CI): 41.6 (33.4, 49.7) vs. 28.6 (21.9, 35.3) ng/ml; P < 0.05]. CONCLUSIONS: The effects of bone metabolism on serum periostin levels may be limited at 9-15 years of age. Further studies are required to determine reference values in adolescents.

Photoimmunotherapy with surgical navigation and computed tomography guidance for recurrent maxillary sinus carcinoma.

Photoimmunotherapy (PIT) using lasers to target treatment areas is effective for unresectable locally advanced or unresectable locoregionally recurrent head and neck cancer; however, there are only two devices to target the treatment area. One illuminates tumour tissue through a needle, and the other illuminates tumour tissue superficially. Treating lesions surrounded by bone, such as in maxillary sinus cancer, is difficult. We report the first case of PIT for unresectable recurrent maxillary sinus cancer employing surgical navigation and computed tomography guidance in a 56-year-old man. Although he underwent concurrent chemoradiotherapy for cT4bN0M0 maxillary sinus cancer, the tumour recurred at the primary site 6 months post treatment. Chemotherapy was performed for approximately 1 year; however, the tumour progressed. The tumour involved the anterior wall of the maxillary sinus and caused bone destruction; thus, we believed that PIT with a needle device was possible if the puncture was carefully performed. We used a surgical navigation system for neurosurgery and computed tomography guidance to ensure that intraoperative punctures were accurately performed. The operation time was 1 h 52 min and the treatment was completed as planned. Tumour necrosis and volume reduction were obtained with no severe adverse events, which reduced the patient's pain.

Risk Factors of Free Flap Complications in Reconstruction for Head and Neck Cancer.

Background: Although head and neck reconstruction using free flaps has become a common procedure, flap complications remain a concern. This study aimed to analyze the risk factors of free flap complications and to identify the causes of these complications. Methods: We studied 97 patients with head and neck cancer with intraoral defects who underwent reconstruction using free flaps at Tottori University Hospital between 2011 and 2020. We used a retrospective cohort study design to investigate whether flap complications, including flap necrosis (total and partial) and flap dehiscence, were related to various factors, including the underlying disease condition, treatment status, and surgical factors. Results: Of the 97 patients analyzed, total flap necrosis was observed in one patient (1.0%). The incidence rate of flap complications, including flap necrosis and flap dehiscence, was 29.9%. When the time taken to perform one vascular anastomosis, including preparation of the recipient vessel and flap vessel, exceeded 30 min, the incidence rates of flap necrosis (total and partial) (odds ratio, 8.30; 95% confidence interval, 1.91-36.00; P = 0.005) and flap dehiscence (odds ratio, 3.46; 95% confidence interval, 1.05-11.36; P = 0.041) increased significantly. Conclusion: The time taken to perform one vessel anastomosis was the factor that contributed the most to the incidence of flap complications. Reconstructive surgeons should reduce the incidence of flap complications by keeping the known risk factors of the surgery in mind and by aiming to complete a vascular anastomosis time, including the time taken for the preparation of vessels, of ≤ 30 min per vessel during surgery.

Primary Closure With Posteriorly Based Lateral Tongue Flap Reconstruction After Transoral Videolaryngoscopic Surgery for Tonsil Cancer.

INTRODUCTION: Transoral surgery for head and neck cancer provides excellent oncologic outcomes while preserving speech and swallowing function. When neck dissection and resection of oropharynx are performed concomitantly, there is a risk of creating a communication defect or developing a pharyngocutaneous fistula. To prevent pharyngocutaneous fistula, we performed the reconstruction using a posteriorly based lateral tongue flap for communication defect. PATIENT: A 72-year-old male with oropharyngeal cancer (tonsil cancer) T2N1M0 underwent concomitant transoral videolaryngoscopic surgery and neck dissection. The lateral wall of the oropharynx was resected with the pharynx constrictor muscle and parapharyngeal fat due to infiltration of the parapharyngeal space by the tonsil cancer. The posteriorly based lateral tongue flap was used to close the perforation. There was no leakage to the neck postoperatively. The patient had no problem with phonation or oral intake and remained free of disease at 12 months after treatment. CONCLUSION: For a small defect confined to the oropharyngeal lateral wall, the posteriorly based lateral tongue flap should be considered as a useful option for reconstruction of the oropharynx without impairment of posterior function.

Nasogastric Tube Syndrome: A Severe Complication of Nasointestinal Ileus Tube.

Nasogastric tube syndrome (NGTS) induced by a nasointestinal ileus tube is an uncommon but potentially life-threatening complication. NGTS often becomes serious and progresses to acute upper airway obstruction caused by bilateral vocal cord paralysis or laryngeal infection. Early detection and proper treatment of NGTS are necessary. We describe the case of a 78-year-old patient with this syndrome induced by a nasointestinal ileus tube. At administration, ileus was suspected based on physical examination and thoracoabdominal X-ray findings. A nasointestinal ileus tube was placed through the left nasal cavity. Three days after tube placement, hoarseness and wheezing were found during nutrition support team rounds. Upper airway obstruction was suspected and evaluated immediately with flexible laryngoscopy by an otolaryngologist. The nasointestinal ileus tube was removed. The symptoms decreased with prompt proper management. Immediate removal of the tube and early recognition of symptoms are the first steps in the treatment for this syndrome, in addition to the initiation of steroid, proton pump inhibitor, and antibiotic therapy. The cause of NGTS is thought to be continuous pressure on the hypopharynx and cervical esophagus. NGTS should be considered in patients with either nasogastric or nasointestinal ileus tubes. Early diagnosis and proper management of NGTS are important.

Use of Cervical Ultrasonography in Globus Sensation Investigation: A Retrospective Cohort Study.

BACKGROUND: A globus sensation is one of the most common complaints in otolaryngological practice. Patients with no associated abnormalities detected during the usual examinations performed in ENT clinics, are being diagnosed with globus sensation. Cervical ultrasonography is usually not performed in ENT clinics; however, it is useful in screening diseases of the subcutaneous tissue/organs, whose detection is not possible with the routine ENT examinations. The purpose of our study was to elucidate whether cervical ultrasound examination identifies abnormalities in patients with globus sensation. METHODS: A single-centre retrospective cohort study. Cervical ultrasonographic examinations were performed on patients with globus sensation at the Department of Otolaryngology, Head and Neck Surgery of Tottori university hospital, a tertiary care centre, from January 2013 to September 2017. The subjects were 74 patients who complained of globus sensation with no abnormality in general otolaryngological examination including laryngoscopy. RESULTS: Ultrasonography detected structural abnormalities in 60.8% of the patients with globus sensation: thyroid disorders in 41 patients, including: 35 patients with thyroid nodules, 4 patients with Hashimoto's disease, 1 patient with Grave's disease, and 1 patient with subacute thyroiditis; Sjögren syndrome in 2 patients; and cervical lipoma in 1 patient. Furthermore, 2 patients with thyroid disorders had concomitant esophageal cancer. CONCLUSION: Cervical ultrasonography identified thyroid disorders in patients with globus sensation, despite the normal ENT status. Therefore, it would be appropriate to adopt cervical ultrasonography as a routine examination at ENT clinics for patients with globus sensation.

Current Status of Transoral Surgery for Patients With Early-Stage Pharyngeal and Laryngeal Cancers in Japan.

As the laryngopharynx is closely related to swallowing, speech, and phonation, it is necessary to consider not only disease control but also a minimally invasive approach for the treatment of laryngopharyngeal cancer. Transoral surgery has been reported to be a minimally invasive method for treating these diseases. Transoral videolaryngoscopic surgery (TOVS) and endoscopic laryngo-pharyngeal surgery (ELPS) have been developed in Japan and recently emerged as treatments for patients with early stage pharyngeal and laryngeal cancers. However, securing an appropriate field of view and a narrow operating space during TOVS or ELPS are critical issues to be resolved for these surgeries. The clinical significance and safety of transoral robotic surgery (TORS) using the da Vinci Surgical System have been widely reported to provide surgeons with increased visualization and magnification, resulting in precise surgical margins and rapid functional recovery. In this context, a multi-institutional clinical study was conducted to evaluate the treatment outcomes of TORS for the treatment of laryngopharyngeal cancer in Japan, and the da Vinci Surgical System for oral robot-assisted surgery for these diseases was approved by the Pharmaceutical Affairs Agency in August 2018. This review provides an overview of the therapeutic effects of TOVS, ELPS, and TORS, with a particular focus on these therapeutic results in Japan.

Hemostatic Control with Gelatin Sponge and Quantum Molecular Resonance Coagulation in a Case of Glomus Tympanicum.

Surgical removal of tumor is the primary treatment of choice for glomus tympanicum (GT). However, because the tumor has abundant blood flow, bleeding control is crucial, and preoperative embolization may be performed. Here, we report the case of a 46-year-old female who visited our hospital with a complaint of right pulsatile tinnitus. A red pulsatile mass was found in the right tympanic cavity, and she was diagnosed with class B1 GT and subsequently underwent surgical treatment. We judged that bleeding could be controlled by intratympanic cavity manipulation alone and decided to perform transmeatal tumor resection without preoperative arterial embolization. After creating a tympanomeatal flap and performing an atticotomy, some pieces of Spongel® were inserted between the tumor and the tympanic wall. The Spongel® absorbed the blood and created a space between the tumor and tympanic wall, which allowed for the insertion of the tip of the Vesalius® handpiece to coagulate the tumor. The coagulation caused the tumor to shrink, thereby widening the space and allowing for further resection. Although the surgical manipulation caused bleeding, complete resection was achieved by the application of Spongel® and coagulation with Vesalius®. Since the tip of the Vesalius® was not burned, hemostasis was successfully achieved, and the operation proceeded while maintaining a clear field of view. There was little bleeding and no postoperative complications. The patient was discharged on the sixth postoperative day. One year after surgery, pure tone audiometry showed no change in the level of bone conduction. Spongel® and Vesalius® are useful tools that allow to safely perform surgeries even in narrow spaces such as the tympanic cavity.

Characteristics of repeated recidivism in surgical cases of cholesteatoma requiring canal wall reconstruction.

OBJECTIVE: Few reports discuss the characteristics of repeated recidivism of cholesteatoma. We describe the clinical characteristics of patients with cholesteatoma who experienced at least two recidivism episodes after initial surgery for cholesteatoma requiring canal wall reconstruction. METHODS: We reviewed the medical records of 11 patients who underwent surgery for cholesteatoma with canal wall reconstruction at our department between April 2008 and March 2018 and subsequently experienced two relapses that necessitated revision surgery involving tympanomastoidectomy with canal reconstruction. Patient age at the time of the first surgery ranged from 6 to 56 (mean, 25.7) years. Seven (63.6%) of the 11 patients were male. These 11 patients were classified according to the type of recidivism, and their characteristics (pathology, operation date, operation method, pattern of relapse, and position of recurrence) were investigated. RESULTS: Four cases involved secondary residual cholesteatoma, with the mean interval between the first revision surgery and the second revision surgery being 23.8 (range, 11-39) months. Secondary residual sites included the anterior tympanic cavity, tympanic sinus, and anterior end of the reconstructed cartilage of the canal wall. The other seven cases involved secondary recurrence, with the mean interval between the first and the second revision surgery being 26.1 (range, 12-57) months. The sites of recurrence were at the edges of the reconstructed cartilage. One notable case involved the cartilage junction, leading us to hypothesize that retraction of the temporal muscle flap and the patulous Eustachian tube was the underlying cause. CONCLUSION: For residual cholesteatoma, strict measures are necessary to maintain the operation under clear view, and more careful follow-up is necessary in patients who have had previous surgery at another hospital. For recurrent cholesteatoma, it was recognized that Eustachian tube function must be ascertained in advance, and careful observation of the reconstructed cartilage edge is necessary.

A Novel Concept for Surgical Management of a Traumatic Comminuted Cricoid Fracture.

The cricoid plays 2 key roles: phonation and maintenance of the airway frame, both of which are lost in cases of comminuted cricoid fractures. The management of these 2 functions becomes a challenge in planning surgical treatment. We report the treatment course in a case of traumatic comminuted cricoid fracture that was resolved with good airway and phonatory functions. A 25-year-old man fell down the stairs and complained of respiratory discomfort and hoarseness of voice. A computed tomography scan showed comminuted cricoid fracture; therefore, surgery was performed to restore the patient's airway and phonation functions. We found that the airway was maintained by the anterior part and that the phonation depended on the posterior part of the cricoid. This novel concept helped clarify the treatment goal in this case of comminuted cricoid fractures. Furthermore, it is important that the anterior part of the cricoid is reconstructed with sufficient internal diameter, while the posterior part of the cricoid is reconstructed in the correct position.

A Case of Gorham-Stout Disease Treated with Fistula Closure by Transmeatal Approach.

Gorham-Stout disease, a rare and intractable disease of unknown etiology, causes systemic bone lysis and replacement with lymphoid tissue. Here, we report a case of Gorham-Stout disease with cerebrospinal fluid leakage in a 16-year-old boy. The patient complained of nasal discharge, right ear obstruction, fever, and headache. A computed tomography scan of the head showed osteolysis around the right internal carotid artery, vestibule, and cochlea and osteolytic changes in the left parietal bone. It was suggested that the patient had bacterial meningitis owing to the leakage of cerebrospinal fluid from the fistula caused by the temporal bone osteolysis. He was treated with meropenem, and a transmeatal fistula closure and a bone biopsy of the left parietal bone were performed. Intraoperatively, osteolysis was observed on the promontory and around the internal carotid artery. The fistula was closed by dense filling and compression around the fistula, in the middle ear cavity, and in the external auditory canal. The symptoms disappeared after the surgery. Bone biopsy showed the presence of a lymphangioma, and Gorham-Stout disease was diagnosed. Prophylactic bisphosphonate therapy was initiated. A 4-year follow-up revealed no progression of the disease.

Sequential Evaluation of Swallowing Function During Chemoradiotherapy for Head and Neck Cancer.

BACKGROUND: Many studies have addressed chronic dysphagia resulting from chemoradiotherapy for head and neck cancer (HNC) because of its severity, but changes in the swallowing function during chemoradiotherapy has been rarely reported. This study aimed to elucidate the changes in the swallowing function during chemoradiotherapy for HNC. METHODS: From April 2018 to July 2020, 20 patients who underwent definitive or postoperative chemoradiotherapy at our hospital for head and neck squamous cell carcinoma were evaluated by flexible endoscopy with the Hyodo scoring system for swallowing, the Penetration-Aspiration Scale (PAS), and the Functional Outcomes Swallowing Scale (FOSS). RESULTS: Assessments at the start of treatment, at 40 Gy, and at the end of treatment yielded these mean values: Hyodo score-0.39, 1.22, and 2.56; PAS-1.00, 1.05, and 1.5; FOSS-0.2, 0.55, and 1.1, respectively. The Dunn multiple comparison test was used for analysis to determine significance (P < 0.05). The Hyodo score and FOSS were significantly increased at the end of treatment versus initial evaluation; however, score was maintained at a tolerable level for oral intake. PAS did not show a significant increase. CONCLUSION: In conclusion, changes in the swallowing function during chemoradiotherapy for HNC were mild, and swallowing function was maintained at a tolerable level for oral intake.

Invasive Fungal Rhinosinusitis with Orbital Apex Syndrome Leading to Brain Abscess in a Patient with Ulcerative Colitis.

We report the case of a 65-year-old male who presented with a 1-week history of right periorbital pain and progressive visual loss. He had a history of ulcerative colitis and was taking oral corticosteroids and mesalazine. Neurological and radiological examination demonstrated a rare case of invasive fungal rhinosinusitis that began with orbital apex syndrome. Initial endoscopic sinus surgery was performed and fungal culture identified Aspergillus fumigatus. Although antifungal treatment was started empirically before the operation, the patient had improved orbital pain but continued to have decreased right vision. Five months after the first surgical procedure, his condition deteriorated, including loss of consciousness, and a right temporal lobe abscess was found and surgically drained. Since then, the patient received antifungal treatment for 4 years without recurrence. Invasive fungal rhinosinusitis with orbital apex syndrome should be treated with long-term postoperative antifungal medication. It should be noted that even in immunosuppressive individuals such as ulcerative colitis, fungal rhinosinusitis with orbital apex syndrome may become severe.
