The fine anatomy of the nostril sill has a great deal of variability among the individuals.The nostril sill deformity is included in the nasal deformities after cleft lip repair,which has been paid more attention.In this article,we review the anatomy of the nostril sill,the features of nostril sill in cleft lip deformities,and the techniques of the nostril sill deformity repair.

Objective To investigate features of maxillary morphology in unilateral cleft lip and palate (UCLP) with maxillary retrusion and the dissimilarities of retruded maxilla.Methods Craniofacial measurements were done in 32 UCLP adult patients with maxillary retrusion (GC), 24 adult patients in class Ⅲ (GⅢ), and 32 healthy adults (GN).The CT slice data was reconstructed into a 3D video model and measured by Mimics 16.01.Results The maxillary volume (GM) and the volume composed of maxilla and maxillary sinuses (GT) were significantly smaller (P<0.05) in GC.The anterior and posterior parts of the maxillary length (A1-P3M⊥CP and P3M-P6M⊥CP) and overall maxillary length(A1-P6M⊥CP)at the dental level were all significantly reduced (P<0.05).There was no significant difference of the distances of A1⊥CP between the GC and GⅢ groups, while the P3M-CP and P6M-CP in the GⅢ group were significantly shorter (all P<0.05).The anterior and overall maxillary length at the dental level (A1-P3M⊥CP and A1-P6M⊥CP) in the GC group was significantly smaller than that in the GⅢ group (all P<0.05).Conclusions The decreased prominence of maxillary complex could be caused by the shortened maxillary length in UCLP patients;the posterior position of the maxilla is more obvious than that of GC group in class Ⅲ patients.

OBJECTIVETo classify the patients with cleft lip and palate who need orthognathic surgery and to propose the corresponding operations.

METHODSFrom January 2005 to May 2015, 121 patients with cleft lip and palate diagnosed as maxillary retrusion were treated by orthognathic surgery. Inclusion criteriar: (1) male aged over 16, female aged over 14; (2) diagnosed as non-syndromic cleft lip and palate without systemic disease and other genetic diseases; (3) without previous orthodontic and orthognathic treatment; (4) having no other craniofacial malformation. Maxillary features and repaired types were recorded.

RESULTS93 patients were included and divided into two categories depended on the dental crowding. Class I: the teeth quantity and bone quantity is coordinated, space analysis ≤ 4 mm (mild dental crowding). The forward distance of maxillary less than 6 mm was defined as Class I a (36 cases) more than 6 mm as Class I b (28 cases). Class II: the teeth quantity and bone quantity is not coordinated, space analysis > 4 mm ( moderate or severe dental crowding). After the simulation of distraction osteogenesis, the anterior crossbite was corrected defined as Class II a (23 cases), not corrected defined as Class II b (6 cases). Class I a were corrected by conventional orthognathic surgery. While Class I b were corrected by Le Fort I maxillary advancement using distraction osteogenesis. Class II a were repaired just by anterior maxillary distraction. While Class II b need to combine conventional orthognathic surgery with anterior maxillary distraction. All the patients were satisfied with the treatment effect.

CONCLUSIONSThe patients of cleft lip and palate with maxillary retrusion who need orthognathic surgery can be classified as the method mentioned above, and then choose the appropriate operations.

Objective: This study is to repair nostril sill deformity in the cleft lip patients by reconstructing the first auxiliary muscle tension line group and to assess the therapeutic outcome. Methods: 437 cleft lip patients with nostril sill deformity underwent the surgery from January 1, 2012 to November 1, 2016.They were treated using the technique of first auxiliary muscle tension line group reconstruction to repair the deformity. Aesthetic correction evaluations were rated by the GAIS. Random digit was used to randomly select 24 patients during the follow-up for three-dimensional measurement and analysis. The preoperative and postoperative symmetry of the nostril sills were evaluated by paired t test. Results: Mucosal ischemia or wound infection occurred in 11 cases, left obvious scar on the nostril floor. Surgical incisions of the other patients were primary healing. After 6 months to 3 years follow up, GAIS questionnaires of 378 patients demonstrated that 84% patients reported great or moderate improvement of nostril sills. Three-dimensional measurements of 24 patients suggested that there were no significant differences of the nostril sill and the nasal ala between the cleft side and the normal side. Conclusions First auxiliary tension line group reconstruction, which is to restore biomechanical balance rather than merely increase muscle volume, is an effective method of nostril sill repair in the cleft lip patients. Post-operatively, the patients achieved a stable and natural nostril sill, a middle columella, as well as a narrowed nasal ala.

Objective:To analyze the clinical characteristics and risk factors of rheumatic diseases complicated with Pneumomediastinum (PnM).Methods:A retrospective analysis of 94 inpatients with rheumatic diseases associated PnM from Peking Union Medical College Hospital and Shanxi Bethune Hospital between January 1998 and October 2018 was carried out. Patients were divided into idiopathic inflammatory myopathies (IIM) and the non-IIM group. Clinical features, laboratory examinations and treatment were compared between the two groups. Cox proportional hazard model was used to investigate the risk factors for prognosis.Results:A total of 94 patients were included in the study, with an average age of (45±14) years. Forty-five (48%) of them were male. There were 62 patients in the IIM group and the other 32 were in the non-IIM group. Sixty-nine patients had predisposing factors before PnM. Severe cough and assisted mechanical ventilation were the most common causes. Compared with the non-IIM group, the incidence of digital vasculitis (29% vs 6%, χ2=6.540, P=0.008), arthritis (60% vs 28%, χ2=8.409, P=0.004), interstitial lung disease (ILD)(98% vs 78%, χ2=11.129, P=0.002) were higher in the IIM group, treatment with cyclophosphamide was higher in the IIM group ( χ2=4.458, P=0.035). There was non-significant difference in mortality between the two groups during hospitalization (50% vs 59%) and 6 months after PnM (64% vs72%) ( P>0.05). Pulmonary infection was the only risk factor for poor prognosis [ HR=3.131, 95% CI (1.025, 9.561), P=0.045], in which bacteria infection was the most common cause (65/75, 86.7%). Conclusion:PnM is a severe complication of rheumatic diseases. To get a good prognosis, rheumatol-ogists should balance the benefit and risk of infection of immunosuppressive therapy.

OBJECTIVE: To compare the performance of serum cancer antigen 125 (CA125), human epididymis protein 4 (HE4), Risk of Ovarian Malignancy Algorithm (ROMA) and Copenhagen index (CPH-I) for differential diagnosis of benign and malignant diseases in patients with ovarian mass. METHODS: We retrospectively analyzed the data of 719 women with pelvic mass, and the performance of preoperative serum levels of CA125 and HE4, ROMA and CPH-I for differential diagnosis of the masses was compared. RESULTS: Of the 710 women analyzed, 531 were diagnosed with benign ovarian lesions, 44 with borderline ovarian tumors (BOTs), 119 with epithelial ovarian cancers (EOCs), and 25 with non-EOCs. In differentiating ovarian cancer (OC) and BOT from benign lesions, the area under the receiver-operator characteristic (ROC) curve (AUC) was 0.854 for HE4, 0.856 for ROMA, 0.854 for CPH-I, and 0.792 for CA125, demonstrating better diagnostic performance of HE4, ROMA, and CPH-I than CA125 alone; the diagnostic sensitivity was 56.9% for HE4, 70.2% for CA125, 69.1% for ROMA, and 63.8% for CPH-I; the specificity was the best with HE4 (94.4%) and CPH-I (94.7%). In sub-analysis of EOC benign lesions, the AUCs of HE4, ROMA, and CPH-I increased to 0.946, 0.947, and 0.943, respectively, all greater than that of CA125 (0.888). In other sub-analyses, HE4, ROMA, and CPH-I all showed greater AUCs than CA125 alone. CONCLUSIONS This study confirms the accuracy of HE4, ROMA, and CPH-I for differentiating malignant from benign ovarian mass, and all these 3 tests show better performance than CA125. Furthermore, HE4 and CPH-I is superior to ROMA and CA125 in terms of specificity, while CA125 and ROMA have better diagnostic sensitivities.

Objective: To analyze the clinical features of respiratory epithelial adenomatoid hamartoma (REAH) in the nasal cavity. Methods: Clinical datas of 23 patients, who were hospitalized in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University, from February 2016 to February 2018 with histopathologically proved REAH in the nasal cavity were reviewed. There were 18 males and 5 females, with the age range from 16 to 71 years old. The most common area, main symptoms, surgical methods and follow-up results were analyzed. Results: The most common area was olfactory cleft (21 cases), and the mainly symptom was nasal congestion (18 cases). All the patients received transnasal endoscopic surgery and had no recurrence during following-up from three months to one year. Conclusions The most common area of REAH in the nasal cavity is the olfactory cleft. Histopathological result is needed to make a definite diagnosis. Complete surgical resection is the main treatment.
