RESUMEN
Objective:According to the characteristics of endoscopic transnasal and transoral surgery for infratemporal fossa tumors, we divided and named subzones of the infratemporal fossa, to explore the approaches of endoscopic transnasal and transoral surgery for infratemporal fossa tumors, and to analyze their advantages and disadvantages. Methods:We retrospectively analyzed the clinical data of 36 patients with benign tumors of infratemporal fossa successfully resected through nose or mouth under endoscope, summarized and analyzed the localization characteristics of these tumors in infratemporal fossa, and made a subzone naming rule of infratemporal fossa. We also summarized the selection principles, advantages and disadvantages of endoscopic transnasal and transoral surgical approaches. Results:The infratemporal fossa area is divided into ABC area. Area A is the fat pad area posterolateral of maxillary sinus. Area B is further divided into B1 ï¼above the plane of maxillary sinus floor, anterior styloid processï¼, B2 ï¼below the plane of maxillary sinus floor, anterior styloid processï¼, and B3 ï¼posterior styloid process to anterior vertebraï¼; Area C is retropharyngeal and eustachian tube area. The location of the tumor in the infratemporal fossa determines the choice of transnasal and transoral approaches. All tumors were completely removed, and no tumor recurred during the follow-up. A few patients had temporary local sensory function decline, and recovered during the follow-up. Conclusion:The infratemporal fossa region naming rule according to the characteristics of endoscopic transoral and transnasal surgery approach is simple and practical, which can effectively guide the operation of the infratemporal fossa region and has clinical application value.

OBJECTIVES: To analyze the clinical features and otologic manifestations of first branchial cleft anomalies (FBCAs) and the disparity between Work's classification, and to explore the relationships between postoperative facial paralysis and features of FBCAs. STUDY DESIGN: Retrospective clinical study. METHODS: A retrospective analysis of 109 patients with FBCAs was conducted, including clinical characteristics and otologic features. Pearson chi-square tests and Fisher's exact tests were used to compare disparity between Work's classification, and the impact factors of postoperative facial paralysis among 86 patients who were explored in follow-up. RESULTS: Patients with FBCAs presented with otologic symptoms, including cysts or fistula in the external auditory canal (EAC) and periauricular (43.2%), microtia (3.7%), EAC web (1.8%), otitis media (1.8%), and otorrhea (4.6%). Eighty-five cases (78.0%) were type I FBCAs and 24 (22.0%) were type II. Compared to type I FBCAs, type II (58.3%) was more likely to be located deep to the facial nerve (FN) and to have superficial parotidectomy on them (79.2%). This difference was statistically significant (P < .001). FBCAs deep to the FN had a higher incidence of postoperative facial paralysis (P < .05). CONCLUSION: The majority of patients (55.0%) had otologic symptoms. The FBCAs of Work type II was commonly deep to the FN and superficial parotidectomy was frequently performed. Postoperative facial paralysis was associated with FBCAs located deep to the FN, but not with Work's type. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1008-1014, 2022.

Objective:To investigate the application and efficacy of pedicled middle turbinate mucosal flap in transnasal endoscopic repair of cerebrospinal fluid rhinorrhea. Methods:15 patients with cerebrospinal fluid rhinorrhea were retrospectively analyzedï¼including 13 patients with simple cerebrospinal fluid rhinorrhea ï¼86.7%ï¼ and 2 patients with cerebrospinal fluid rhinorrhea with meningoencephalocele ï¼13.3%ï¼. According to the location of the fistula, the pedicled middle turbinate mucosal flap under nasal endoscopy was used to repair cerebrospinal fluid rhinorrhea, in which 5 cases ï¼33.3%ï¼ had leakage at the top of the sieve and 8 cases ï¼53.3%ï¼ had leakage at the sieve plate. Two cases had leakage at the lateral racess of sphenoid sinus. Results:All cases of cerebrospinal fluid rhinorrhea were repaired successful and the mucosa epithelialized well in the operative area. There was no recurrence of cerebrospinal fluid rhinorrhea or other complications during the follow-up period of 4-24 months ï¼average 13 monthsï¼. Conclusion:The pedicled middle turbinate mucosal flap has a high success rate for repairing cerebrospinal fluid rhinorrhea, and the nasal cavity damage is small, which is worthy of clinical promotion.

Objective:To analyze the clinical effect of nasal endoscope-assisted nasal columella approach in the correction of nasal septum deviation and crooked nose deformity. Methods:The clinical data of 33 patients with deviation of nasal septum with crooked nose deformity in First Affiliate Hospital of Air Force Military Medical University from January 2016 to June 2019 were collected. All patients underwent surgery under general anesthesia. Nasal columella inverted "V" incision was used to expose and release. The deviated nasal septum cartilage and bone were removed with the assistance of nasal endoscope. Twelveï¼36.4%ï¼ patients underwent osteotomy of nasal bone and frontal process of maxilla at the same time, 13ï¼39.4%ï¼ patients used autologous nasal septum to reshape the tip, back and external nose. Results:During a follow-up of 18 months to 60 months, 30ï¼90.9%ï¼ patients were satisfied with the improvement of postoperative nasal function, 3ï¼9.1%ï¼ patients were basically satisfied; 23ï¼69.7%ï¼ patients were satisfied with the appearance of the nose after operation, 8ï¼24.2%ï¼ patients were basically satisfied, and 2ï¼6.1%ï¼ patients were dissatisfied. No postoperative complications such as nasal adhesion, nasal septum perforation, nasal septum hematoma and nasal dorsal collapse occurred in all patients. Conclusion:The nasal endoscope-assisted nasal columella approach and the correction of nasal septum deviation and crooked nose deformity can solve the nasal deformity and nasal ventilation function at the same time, realize the unity of cosmetology and function, and reduce the frequency and cost of surgical treatment at the same time. The effect is good, and the patients benefit greatly.

Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of nasal mucosa provoking T helper cell (Th) 17 response. Chlorogenic acid (CGA), one of the most abundant polyphenol compounds in various agricultural products, possesses antiviral, anti-inflammatory, and antibacterial properties. However, the effect of CGA on AR is unclear. Thus, our study explored the effect of CGA in modulating AR-related symptoms and immunoreaction, especially Th17 response. AR mice were induced by ovalbumin (OVA) administration and further treated with CGA or dexamethasone (Dex). The frequencies of rubbing and sneezing of AR mice were recorded. Histopathological analysis of nasal mucosa was conducted by Hematoxylin-Eosin and Periodic acid-Schiff stainings. The serum and nasal mucosa levels of OVA-immunoglobulin (Ig)E, interferon (IFN)-γ, retinoic acid-associated nuclear orphan receptor (ROR)-γt, and interleukin (IL)-17A were measured by enzyme-linked immunosorbent assay, quantitative reverse-transcription polymerase chain reaction (qRT-PCR), or Western blot. The ratio of CD4+IL-17+Th17 cells to CD4+ T cells in peripheral blood of AR mice was assessed by flow cytometer. CGA diminished the frequencies of rubbing and sneezing of AR mice in a concentration-dependent manner. CGA attenuated histopathological abnormalities and decreased goblet cell number in nasal mucosa of AR mice. CGA decreased the serum levels of OVA-IgE, ROR-γt, and IL-17A, while increasing the serum level of IFN-γ in AR mice. Meanwhile, CGA decreased the ratio of CD4+IL-17+Th17 cells to CD4+T cells in peripheral blood and the mRNA and protein levels of IL-17A and ROR-γt in AR mice. CGA ameliorated AR-related symptoms in mice by regulating Th17 cells, which could be a candidate for the treatment of AR.

Objective:To discuss the diagnosis and treatment process of skull base osteoradionecrosis and improve the recognization of this disease. Method:We reviewd skull base and nasopharyngeal osteoradionecrosis in 7 patients retrospectively, including 5 nasopharyngeal carcinoma, 1 squamous cell carcinoma of sphenoid sinus, 1 adenoid cystic carcinoma; 6 patientd received skull base debridement surgery and the other one attempted but failed because of her unstable condition. Result:Follow-up period ranged from 3 to 31 months ï¼mean 11.5 monthï¼. During the review time, 2 patients died, 1 patient still had osteoradionecrosis with partly alleviated clinical symptom. At the latest follow-up visit, she was diagnosed as tumor recurrence and was advised to take targeted therapy by multi-discipline team; the symptom was significant improved in the rest of the patients. Conclusion:Osteoradionecrosis of skull base is often associated with other post-radiotherapy related complications. Once diagnosed definitely, extensive skull base debridement surgery should be performed in early time, which can significantly relieve symptoms, improve living quality and reduce the incidence of lethal complications.
