Intravascular papillary endothelial hyperplasia of the maxillary sinus extending into the contralateral nasal cavity.

INTRODUCTION: Intravascular papillary endothelial hyperplasia (IPEH) predominantly occurs in the subcutaneous and dermal regions and rarely originates from the sinonasal mucosa. CASE PRESENTATION: We report on the case of a 58-year-old male patient who presented with progressive bilateral nasal obstruction, left-sided epiphora, and intermittent epistaxis. Computed tomography revealed a soft tissue opacity in the left maxillary sinus with intersinusoidal nasal wall demineralization, extending into the surrounding ethmoid cells and the right nasal cavity through a contralateral deviation of the nasal septum. Contrast-enhanced T1-weighted magnetic resonance imaging further confirmed these findings. The IPEH originating from the maxillary sinus extended into the contralateral nasal cavity, and it was successfully removed using an endoscopic endonasal approach, avoiding overly aggressive treatment. CONCLUSION: This case report highlights the diagnostic challenges of IPEH in the sinonasal region and the importance of considering IPEH as a differential diagnosis in patients presenting with nasal obstruction, epiphora, and intermittent epistaxis.

Clinical Approach to Dental Root Canal Filler-Induced Maxillary Sinus Fungal Mass Using Transnasal Endoscopy.

Accidentally extruded root canal filler within the sinuses may induce maxillary sinusitis with fungal mass. The authors describe 2 cases of gutta-percha-induced fungal masses in the left maxillary sinus of 2 women. The lesions were evaluated preoperatively using both computed tomography and magnetic resonance imaging, providing comprehensive insights into the condition. In one patient, the lesion was located such that it could be resected through the middle meatal antrostomy alone. However, the second patient presented with an anteroinferiorly situated lesion that necessitated not only a transnasal approach but also an endoscopic modified medial maxillectomy. Both patients recovered uneventfully after surgery. This case series is the first published report of 2 cases of gutta-percha-induced maxillary sinus fungal masses, with their imaging findings, successfully treated through different routes through transnasal endoscopic surgery. These reports highlight the need for a collaborative approach between dental practitioners and otolaryngologists. In addition to the patient's wishes, surgical interventions must consider the unique characteristics of each case and the potential for collaboration across different medical specialties.

A Patient With Lobular Capillary Hemangioma Originating From the Inferior Turbinate Following Cauterization With Silver Nitrate.

Lobular capillary hemangiomas (LCH), which usually originate in the skin and mucous membranes of the oral cavity, are uncommon from the posterior portion of the inferior turbinate. Although the exact cause of LCH in the nasal cavity has not been elucidated, trauma, caused by factors such as intranasal packing and habitual nose-picking, has been reported as one of the causes. In addition, 2 cases of LCH caused by submucosal resection with powered instrumentation to the inferior turbinate have been reported, suggesting that various types of traumas to the nasal mucosa can cause LCH. The authors report the first case of LCH formation in the posterior portion of the inferior turbinate after cauterization with silver nitrate.

A case of perilymphatic fistula caused by surgical drilling with preserved normal hearing.

We introduce our horrible experience of lateral semicircular canal exposure due to unintended drilling during left facial nerve decompression. Nearly half of the canal was drilled-out, however, the membranous labyrinth was preserved and the defect was covered with temporal fascia. Immediately after surgery, the patient complained of vertigo with right beating nystagmus. However, the patient could hear an audible tuning fork sound and the Weber-test showed left-sided deviation. The vertigo gradually subsided and the facial palsy was completely recovered 3 months after the surgery. One and half years later, the patient spent a normal life with normal hearing nevertheless after this terrifying episode.

Emergency videoendoscopic endonasal tracheal intubation for severe upper airway stenosis.

PURPOSE: Upper airway stenosis is one of the most formidable situations in medicine and is frequently encountered in the ENT clinic. We introduce here our method of emergency endonasal endotracheal intubation under videoendoscopic observation. METHODS: Transnasal endoscopic observation was done, and the region of airway stenosis was detected. Then, the endotracheal tube was prepared and the endoscope was inserted into the tube. The endoscope with tube was inserted up to the larynx. Immediately after the administration of lidocaine to the larynx, the endoscope with tube was inserted to the endolarynx and then to the trachea. The endotracheal tube was tightly held in the nostril, and the endoscope was removed. RESULTS: We have encountered four cases this year. The primary disease developing airway stenosis was acute epiglottitis due to pharyngeal and deep neck abscesses in three cases and laryngeal edema due to Ludwig's angina. All patients underwent uneventful intubation, and dyspnea was immediately ceased. CONCLUSION: In cases showing severe suffocation, the clinician should perform airway maintenance even in an outpatient setting apart from a more monitored setting like the operation room. This technique resembles the usual nasal endoscopic laryngeal observation and is done even in the usual ENT office and/or emergency room. The supine position tends to worsen airway stenosis in patients with upper airway stenosis; however, this technique can be performed in a sitting or semi-sitting position. This method is less invasive for patients and also reduces the risk to the medical staff, especially in this COVID-19 era.

Cryosurgical ablation for treatment of common warts on the nasal vestibule.

BACKGROUND: Common warts rarely occur on the nasal vestibule. It should be treated more carefully than other skin lesions because scar contracture results in the narrowing of the external naris, causing nasal obstruction and reducing the patient's quality of life. In this report, we introduce our method for common warts on the nasal vestibule using handheld cryoablation devise. PATIENTS AND OPERATIVE METHODS: We performed a series of four cryosurgical ablation procedures to treat common warts on the nasal vestibule. All the procedures employed a reusable handheld cryoablation device (CRY-AC®, Brymill Cryogenic Systems, Ellington, CT). RESULT: All patients were successfully treated for four to six sessions without any adverse event. CONCLUSION: Cryotherapy for common warts on nasal vestibular is easily performed in an office setting under no anesthesia without bleeding. We believe this easy and safe procedure is suitable as the first line therapy for common wart on nasal vestibular.

Minimally invasive and inexpensive percutaneous abscess drainage using an indwelling needle cannula.

PURPOSE: Abscess is still a formidable disease and requires adequate drainage. Moreover, drainage in the head and neck area needs cosmetic care, especially in the pediatric population. In this report, we introduce our method of percutaneous abscess drainage using an indwelling needle cannula. PATIENTS AND METHODS: Ten pediatric and five adult patients with cervical and/or facial abscess treated with this drainage method were retrospectively reviewed. Using an indwelling needle cannula (18-14 G Surflow®, Terumo, Tokyo, Japan), abscesses were penetrated under ultrasonic examination. Once purulent retention was identified, the inner metal needle was removed and the outer elastic needle was left and fixed. The outer needle was connected to the tube for continuous suction drainage for large abscess. RESULTS: The primary diseases of these abscesses were cervical abscess of dental origin (5), purulent lymphadenitis (3), pyriform sinus fistula (2) and subperiosteal abscess due to mastoiditis (2), circumorbital cellulitis (1), infection of Warthin's tumor (1), and unknown origin (1). The median (range) duration of drainage was 4 days (3-9 days). Abscesses were successfully treated, and no patients required additional incision for abscess drainage. No apparent scars after drainage were observed. CONCLUSION: This technique resembles the usual venous placement of an indwelling needle cannula and is thought to be familiar to physicians. Although simple and inexpensive, this drainage is safe, effective, and minimally invasive for the treatment of abscess.

Impact of Reduced Acidic Earwax pH and Earwax-Determinant Genotypes in Acquired Middle Ear Cholesteatoma.

OBJECTIVE: The development of acquired middle ear cholesteatoma is associated with a single nucleotide polymorphism, 538G>A, in the human adenosine triphosphate-binding cassette transporter C11 (ABCC11) gene, which is a determinant of the earwax morphotype, such as wet- and dry-type earwax; however, the mechanism underlying this association is unclear. We focused on the earwax pH and aimed to elucidate the mechanism between ABCC11 genotypes and acquired middle ear cholesteatoma. STUDY DESIGN: Prospective observational study. SETTING: Single-center, academic hospital. METHODS: We recruited 40 patients with acquired middle ear cholesteatoma who underwent surgery and 115 controls with no history of middle ear cholesteatoma. We assessed the earwax pH and ABCC11 genotypes in all participants. Clinical information was collected from the patients with cholesteatoma. RESULTS: The earwax pH was significantly less acidic in patients with cholesteatoma and those carrying wet earwax genotypes (ABCC11 538G/G or 538G/A) than in the controls and those carrying the dry earwax genotype (ABCC11 538A/A), respectively. Furthermore, earwax pH was significantly positively correlated with high preoperative cholesteatoma stages in the patients with cholesteatoma. CONCLUSION: Our results show that the less acidic earwax pH was significantly related to the development and progression of acquired middle ear cholesteatoma. The less acidic earwax pH may play an important role in the mechanism underlying the association between acquired middle ear cholesteatoma and the ABCC11 gene at site 538.

Combined underwater endoscopic and microscopic surgery for tympanic paraganglioma: A case report.

The resection of middle ear paragangliomas can be challenging given their vascular nature and the small volume of the tympanic cavity, particularly when the tumor in the hypotympanum is close or attached to the internal carotid artery (ICA). We performed combined underwater endoscopic and microscopic surgery for a Class B1 middle ear paraganglioma according to the modified Fisch classification. The suspicious bone in the hypotympanum and around the petrous ICA was drilled with underwater endoscopy. The feeding arteries, the caroticotympanic and inferior tympanic arteries, were suctioned and cauterized under microscopy. To the best of our knowledge, no case of middle ear paraganglioma treated with underwater endoscopy has been reported. Underwater endoscopy, providing a clear operative field with blood and bone dust irrigation, is a good indication for middle ear paragangliomas. In contrast, microscopic preparation for unexpected bleeding is important, particularly when the tumor closely extends to vital structures, such as the ICA or the jugular bulb.

Assessing the Efficacy of Tragal Pumping in a Novel Tympanostomy Tube-Rat Model.

Objective: Tragal pumping (TP) is a practice of pushing on the tragus to raise pressure within the external auditory canal and is a commonly recommended adjunctive maneuver believed to facilitate the introduction of ototopical medications into the middle ear cavity via a tympanostomy tube. To investigate the efficacy of TP in the penetration of eardrops into the middle ear cavity via tympanostomy tube, we established the novel tympanostomy tube-rat model. We investigated the histology of the middle ear to determine the efficacy in moving fluid into the middle ear. Study Design: Prospective controlled animal study. Setting: Animal laboratory in a university hospital. Methods: Ten rats were recruited, and a tympanostomy tube insertion and green dye eardrops into outer ears were performed on bilateral ears. TP was performed only on 1 ear and was not applied on the other ear in each rat. Green dye in a middle ear cavity in hematoxylin and eosin-stained temporal bone sections was evaluated by blinded experts in microscopic anatomy (staining grade) and by using Image J software (staining level). The results of these 2 methods were statistically validated. Results: The staining grade (P < .001) and the staining level (P < .001) were significantly higher in the ears which we applied TP than in the control ears. The results of 2 methods were significantly and positively correlated (r = .898, P < .001). Conclusion: Our results showed that the TP accelerate the penetration of eardrops into the middle ear cavity in the tympanostomy tube-rat model.

Congenital Aural Fistula Developing Between the Third and Fourth Hillocks of the Embryonal Helix and Presenting a Large Temporal Mass: A Case Report.

This report aimed to introduce a very rare presentation of congenital aural fistula and its treatment. A 13-year-old girl presented with a mass on the right temporal region with protrusion of the helix. She noticed a mass a month previously, and the mass gradually swelled with pain. Pus discharged from the pit behind the helix. Mastoiditis was suspected; however, the tympanic membrane was normal. Magnetic resonance imaging revealed a cystic mass in the temporal region. The surgical removal of the mass was performed using a postauricular incision. The mass was cystic and had a stem connected to the pit. Insertion of a probe into the pit showed a connection to the mass. The mass was totally removed with the skin around the pit. Histologically, the cyst connected to the fistula and its lumen was covered with squamous cells. A diagnosis of a congenital aural fistula developed posterior to the helix was made. Considering its location, the fistula had been formed between the third and fourth hillocks of the embryonal helix. Aural fistula developed posteriorly is very rare, and it mimicked a temporal tumor or mastoiditis with a protruding auricle. Careful observation of the skin and consideration from developmental aspects are needed for an accurate diagnosis.

Cholesteatoma Surgery With a Dehiscent High Jugular Bulb Treated With Surgery Assisted With Underwater Endoscopy: A Case Report.

A dehiscent high jugular bulb would be a pitfall in middle ear surgery especially for cholesteatoma. We report a case of cholesteatoma attached to a dehiscent high jugular bulb successfully treated with surgery assisted with underwater endoscopy. To the best of our knowledge, no previous study has reported a case of cholesteatoma with dehiscent high jugular bulb treated with surgery assisted with underwater endoscopy. Owing to the risk of jugular bulb injury, underwater endoscopy is a good indication for middle ear cases with a dehiscent high jugular bulb to obtain a clear operative field and avoid an unexpected air embolism.

Creutzfeldt-Jakob disease with dizziness initially presenting to the otolaryngology department.

Creutzfeldt-Jakob disease is a fatal transmissible prion disease of the central nervous system. Dizziness as an initial manifestation of Creutzfeldt-Jakob disease is rare. However, patients with Creutzfeldt-Jakob disease and dizziness may initially visit the otolaryngology department, but this is uncommon. We report the case of a 56-year-old woman with Creutzfeldt-Jakob disease who initially presented with dizziness as an emergency patient to the otolaryngology department. Primary position upbeat nystagmus was identified using a charge-coupled device camera with infrared illumination. Electronystagmography revealed impaired smooth pursuit and diminished optokinetic nystagmus. Based on these findings, we immediately suspected an intracranial cause of dizziness and reached a presumptive diagnosis of sporadic Creutzfeldt-Jakob disease, thus preventing severe transmission. This case emphasizes that Creutzfeldt-Jakob disease should be included as a differential diagnosis for patients with dizziness and abnormal eye movements, such as primary position upbeat nystagmus, which might be caused by intracranial disease.

Subtotal Petrosectomy With Preservation of Chorda Tympani for Petrous Bone Cholesteatoma: Case Report.

A petrous bone cholesteatoma (PBC) is a rare epidermoid cyst of the petrous portion of the temporal bone. The main treatment is subtotal petrosectomy (SP), which generally involves sacrificing the chorda tympani. We report a case of extensive supralabyrinthine PBC in an elderly patient undergoing hemodialysis that was treated by SP with anatomical preservation of the chorda tympani. To the best of our knowledge, preservation of the chorda tympani during SP has not been previously reported. For maintenance of postoperative taste and appetite, preservation of the chorda tympani is a meaningful maneuver whenever possible.

Upper and Lower Respiratory Mucous Membrane Plasmacytosis with a Cobblestone Appearance: a Case Report.

A 53-year-old woman with a recurrent sore throat, xerostomia, nasal obstruction, and nasal discharge came to our hospital. At the first visit, she did not have a fever, but a blood test showed an intense inflammatory response. She had oral mucosal erosion. She developed dyspnea 2 months later. Nasendoscopy, laryngoscopy, and bronchoscopy showed upper and lower respiratory mucosa cobblestone appearance. Microscopy of the nasal and pharyngeal mucosa biopsy found regular mononuclear inflammatory cell dense submucosal infiltrate, mainly plasma cells. A mucous membrane plasmacytosis diagnosis was made. Prednisolone 1 mg/kg/day rapidly improved bronchial symptoms and cobblestone appearance.

Association Between Earwax-Determinant Genotypes and Acquired Middle Ear Cholesteatoma in a Japanese Population.

OBJECTIVE: A single-nucleotide polymorphism 538G>A in the human ABCC11 gene is a determinant of the earwax morphotype. ABCC11 538GG and GA correspond to wet earwax and 538AA to dry earwax. Despite a putative positive correlation between the frequency of the 538G allele and the prevalence of cholesteatoma, minimal clinical information is currently available. We aimed to evaluate this association between the ABCC11 genotypes and acquired middle ear cholesteatoma. STUDY DESIGN: Case-control study. SETTING: Single-center academic hospital. METHODS: We recruited 67 Japanese patients with acquired middle ear cholesteatoma (cholesteatoma group) and 100 Japanese controls with no history of middle ear cholesteatoma. We assessed the ABCC11 genotypes for all participants. Clinical information was collected from the cholesteatoma group. The genotype data of 104 Japanese people from the 1000 Genomes Project who represent the general population were used. RESULTS: The proportion of participants with ABCC11 538GG or GA was significantly higher in the cholesteatoma group than in the control group or general Japanese population (P < .001). The ABCC11 538G allele frequency was also significantly higher in the cholesteatoma group than in the control group or general Japanese population (P < .001). Multivariate logistic regression analyses revealed a significant association between the ABCC11 genotype and acquired middle ear cholesteatoma (odds ratio, 5.49; 95% CI, 2.61-11.5; P < .001). CONCLUSION: Our results suggest that the ABCC11 genotypes could be associated with the development of acquired middle ear cholesteatoma among Japanese people.

An incidental latent adult hemophilia case found after a tonsillectomy.

Severe bleeding after a tonsillectomy may cause airway obstruction and be life-threatening. We report post-tonsillectomy bleeding in a 32-year-old patient with hemophilia A, who had not been aware of his disease for more than 30 years. He underwent tonsillectomy for recurrent tonsillitis. He denied episodes of bleeding tendency. The preoperative workup was normal, including platelet count, prothrombin time, and activated partial thromboplastin time. The surgery itself was uneventful, but severe bleeding from the inferior pole of the tonsillar bed developed 7 days after surgery. Emergency hemostasis was performed under general anesthesia in the operating room. The patient then remembered several episodes of bleeding tendency. Coagulation tests revealed a mild lack of coagulation factor VIII to 35%, and a diagnosis of hemophilia A was made. Hemophilia might only be found after surgery and can cause life-threatening complications. However, latent hemophilia detected after a tonsillectomy in a 32-year-old adult is very rare. A careful history of bleeding tendency is important to achieve a diagnosis of coagulopathy, perform a safer surgery, and prevent postoperative complications.

Endoscopy-Aided Combined Intraoral and Cervical Approach for a Huge Parapharyngeal Benign Tumor.

We introduce here our surgical approach for the removal of a huge parapharyngeal tumor in 3 cases. Surgery was done under general anesthesia using transnasal intubation. Transoral manipulation was performed first. Using a tongue retractor and an angle widener, a wide surgical field was provided. Incision was made on the palate around the tumor. Tumor was separated from the surrounding tissue, preserving the tumor capsule. Then, a 5-cm small skin incision was made. Both parotid and submandibular glands were pushed upward, and the parapharyngeal space was opened. The tumor was also separated from the surrounding tissue. These manipulations were done under endoscopic observation. Finally, the tumor was pushed laterally and safely removed intraorally. After removal of the tumor, the wounds were closed, and vacuum drainage was settled for a few days. No apparent problems, such as malocclusion and facial palsy, occurred, and the patients were free from disease for more than 10 years. For the removal of a large parapharyngeal tumor, the mandibular swing approach is usually used; however, this approach is invasive, and certain sequelae, such as facial wound and malocclusion, may occur. Our technique enables the safe and less invasive removal of such a huge parapharyngeal benign lesion.

Otitis Media With Effusion Caused by a Parapharyngeal Tumor Showing Normal Nasopharyngeal Findings.

The objective of this study is to evaluate otitis media with effusion (OME) among patients with parapharyngeal tumor. We have experienced 82 parapharyngeal tumor cases and encountered 14 patients complaining of hearing loss due to OME as the initial symptom. These patients showed normal nasopharyngeal findings and the presence of tumor had been detected long time after the beginning of their hearing symptoms (4 months to 13 years: median 2.5 years). Six patients had undergone ventilation tube insertion on the affected ear, which may lead to delay in diagnosis. Pathological examination was performed in 76 of 82 patients. Among these 76 patients, 13 showed OME. Seven patients had malignant lesions, whereas 6 had benign lesions. Therefore, malignant lesions are prone to occur with OME and its relative risk was 2.26 (95% confidence intervals, 1.16-4.42). This difference was statistically significant (P = .044, Fisher test). Otitis media with effusion is a very common disease and is well-known as a primary symptom of nasopharyngeal carcinoma. Therefore, nasopharyngeal observation is necessary for patients with intractable middle ear effusion. However, present 14 patients with OME showed normal nasopharyngeal findings and finally found after an imaging study. From our data, OME is an important but go-by symptom of parapharyngeal tumors. Imaging studies are potently useful for such patients with intractable OME.
