Objective :
To investigate the characteristics of mortality of falls among the elderly in Haishu District, Ningbo City, Zhejiang Province, so as to provide insights into the improvement of fall control strategy.
Methods:
Data pertaining to surveillance of falls in Haishu District from 2017 to 2022 were collected from the Ningbo Municipal Digital Disease Prevention and Control Platform. The trends in mortality of falls in Haishu District from 2017 to 2022 were evaluated using annual percent change (APC). The distribution of demographic characteristics, locations of falls, injury sites, interval from fall occurrence to death and type of falls specified by age were descriptively analyzed.
Results:
A total of 1 206 deaths occurred due to falls among the elderly at ages of 60 years and older in Haishu District from 2017 to 2022, including 414 men and 612 women, with a male to female ratio of 0.67∶1. The average age was (85.20±8.42) years. The average annual crude mortality and standardized mortality of were 101.10/105 and 85.40/105 from 2017 to 2022, respectively, with no obvious changing trends (APC=5.797% and 5.337%, all P>0.05). The standardized death rate of falls in females was higher than that of males (102.60/105 vs. 69.55/105, P<0.05). The average annual mortality of falls appeared a tendency towards a rise with age among the elderly at ages of 60 years and older, with the highest mortality of 147.18/105 seen in the elderly at ages of 85 years and older. Falls predominantly occurred at home (836 cases, 81.48%) and on the same level (881 cases, 85.87%). The injury sites were mainly lower limbs (388 cases, 37.82%) and head (308 cases, 30.02%). In addition, the interval from fall occurrence to death mainly ranged from 24 hours to 6 months (757 cases, 73.79%).
Conclusion
The mortality of falls appeared a tendency towards a rise with age among the elderly at ages of 60 years and older in Haishu District from 2017 to 2022, which was higher in women than in men. The location of falls was predominantly at home and the type of falls predominantly at the same level. High attention to residential environments, and reinforcement of gender- and age-specific interventions are recommended.

Objective :
To explore the main points of clinical treatment of fourth branchial cleft deformity in special positions and to provide a reference for clinical practice.
Methods:
The clinical data of one case of a fourth branchial cleft deformity that occurred in the left anterior chest wall with a fistula below the clavicle are summarized and combined with a literature review.
Results:
The patient complained of repeated swelling and pain under the left anterior chest wall for 2 months. A 10 mm×10 mm fistula with yellow clear liquid exudate from the fistula was observed on the left side below the clavicle. A 20 mm×20 mm×10 mm swelling was immediately adjacent at the superficial cervicothoracic junction of the upper sternoclavicular joint, with no fluctuation and poor activity; this swelling produced slight pain upon pressing. Imaging examinations pointed to cystic lesions. The primary diagnosis was a fourth branchial deformity. A small amount of methylene blue was injected into the patient's subclavian fistula, and a supraclavicular T-shaped incision was made where the cyst contacted the fistula. By turning the flap, all the methylene blue-stained areas and adjacent submucosal tissues were exposed. During the operation, a mass was found on the sternum. The platysma was found deep in the notch, which was incised before excising the surrounding area. The pathological result is the fourth branchial cleft deformity. After 1 week and 3 months of follow-up, the patients had no discomfort and no recurrence. A review of the relevant literature shows that the fourth branchial cleft deformity is a congenital developmental abnormality that occurs in 1% of all branchial cleft deformity. It often presents as a fistula, cyst, or sinus tract and is anatomically located at the neck root and supravicular region. The fistula is close to the medial lower boundary of the sternocleidomastoid muscle. The diagnosis is often made based on its anatomical location, imaging examinations and, ultimately, pathology. The differential diagnoses include other cervical swellings, such as hemangioma and a thyroglossal duct cyst. Surgical resection is a commonly used treatment method. In recent years, endoscopic positioning and internal fistula burning have had good curative effects for recurrent fourth branchial cleft deformity, with a small chance of recurrence or cancer.
Conclusion
Given its unique position, clinicians should make full use of imaging methods to determine the size, anatomical location and course of the lesion when treating the fourth branchial cleft deformity to ensure the complete and safe surgical resection of the lesion and prevent recurrence.

Objective :
investigate the correlation between the ossification of the styloid hyoid ligament and Bell’s facial paralysis and provide a reference for clinical diagnosis and treatment.
Methods:
A case of ossification of the bilateral stylohyoid ligament with Bell's facial palsy caused by ossification of the bilateral stylohyoid ligament was diagnosed by clinical manifestations, differential diagnosis and imaging examination. The surgical plan was determined, and combined surgical resection of the ossified area of the styloid hyoid ligament and the greater horn of the hyoid was performed. Postoperative cefoxitin sodium anti-inflammatory treatment, methylprednisolone hormone treatment, acyclovir antiviral treatment, mecobalamin nutritional neurotherapy, and the relevant literature were analyzed.
Results:
The patient experienced pain when swallowing before surgery, disappearance of right frontal ridges, incomplete eyelid closure, and ptosis of mouth corners. An MRI scan of the brain excluded intracranial space-occupying lesions and resulted in the diagnosis of Bell’s facial paralysis. High-resolution CT of the styloid process confirmed ossification of the styloid hyoid ligament. Styloid process shortening and partial hyoid resection were performed under general anesthesia. Half a month after discharge, the symptoms of sore throat and pain in swallowing disappeared, facial nerve function recovered well, right eyelid closure function recovered well, and right mouth droop improved. The facial nerve function basically returned to normal after 1 month of follow-up. A review of the relevant literature showed that ossification of the stylohyoid ligament to form pseudojoint dilation can locally stimulate the peripheral facial nerve and lead to facial paralysis symptoms.
Conclusion
Ossification of the styloid hyoid ligament is usually characterized by pharyngeal pain, which can be confirmed by imaging examination. Ossification of the styloid hyoid ligament with facial paralysis is rare in the clinic, so it is necessary to make a clear diagnosis and treat the symptoms.

Objective:
To study the diagnostic accuracy and the distance between the root of maxillary posterior tooth and the maxillary sinus using panoramic radiography and cone beam computer tomography; to provide basic information for clinicians to treat diseases in the maxillary posterior region.
Methods:
Eighty patients were included in this study. A total of 671 specimens were measured for the distance between the root tip and the maxillary sinus floor in both imaging modalities.
Results :
The roots that did not contact the sinus floor or contacted but did not project into the sinus cavity showed an agreement of 82% and 70% when using panoramic radiography. Forty-eight percent of the roots that projected into the sinus cavity in panoramic radiography showed protrusion into the sinus with cone beam computer tomography (CBCT). For panoramic radiography and CBCT showing root projections into the sinus cavity, the average distances were 2.19 ± 1.82 mm and 1.47 ± 1.01 mm, respectively. There was a significant difference between the two values (P < 0.05).
Conclusion
Panoramic radiography is more accurate when roots of maxillary posterior teeth do not contact the sinus floor or contact it. However, it has a lower accuracy rate when the tooth roots protrude into the sinus.

Objective To investigate the short-term quality of life in patients after single-direction video-assisted thoracic surgery (VATS) for lung cancer, and explore the related influencing factors. Methods Patients who underwent single-direction VATS for lung cancer in the Department of Thoracic Surgery, West China Hospital, Sichuan University from July 2020 to August 2021 were continuously selected. The QLQ-C30 and QLQ-LC13 were used to evaluate the quality of life of the patients after the surgery, and the influencing factors were analyzed. Results A total of 193 patients were collected. There were 73 males aged 59.44±11.40 years, and 120 females aged 53.73±11.15 years. The QLQ-C30 score of the patients after single-direction VATS for lung cancer was 69.09±20.21 points. Univariate analysis and Pearson correlation analysis showed that age, occupation, anesthesia time, postoperative complications, postoperative antibiotic use time, postoperative hospital stay, insomnia, economic stress, hemoptysis, chest pain, dysphagia, arm or shoulder pain were associated with the quality of life (P≤0.05). The results of multiple regression analysis showed that anesthesia time, economic pressure, insomnia and chest pain had a significant impact on the overall quality of life 30 days after the surgery (P≤0.05). Conclusion The anesthesia time, economic pressure, insomnia and chest pain are independent influencing factors for the quality of life after the VATS lung cancer surgery.
