Critical analysis of anatomical landmarks within the sphenoid sinus for transsphenoidal surgery.

The transsphenoidal approach to the sellar region has been introduced more than a 100 years ago. It is the accepted standard operative corri … sphenoid sinus (DSS), direction of the septum sinuum sphenoidalium (SSS), and the distance between vomer and clivus (VCD). The overall mean ICD was 16.2 mm, with patients suffering from adenomas showing a mean ICD of 15.8 mm compared with an average 16.5 mm in the control group. DSS was equal for both groups (adenoma group: mean 31.5 mm; controls: mean …

Improving retention of pediatric feeding tubes with a nasal bridle: a randomized controlled trial.

BACKGROUND: Nasoenteric feeding tubes are necessary in hospitalized children to deliver nutrition and medication. Traditionally, adhesive tape secures these feeding tubes but fails to prevent 40% of tube dislodgements. The nasal bridle, a thin plastic anchor placed around the vomer bone, is an increasingly used method for tube securement. Our objective is to compare AMT Bridle Pro® nasal bridle versus conventional tape to safely reduce tube dislodgement in pediatric patients. METHODS: A prospective, open-label randomized controlled trial was carried out between February 2020 and January 2021 …

Endoscopic choanoplasty without stenting for congenital choanal atresia repair.

OBJECTIVE: To present our experience with an endoscopic technique for congenital choanal atresia transnasal repair without the use of intranasal stents. METHODS: Twenty-one patients with congenital choanal atresia (11 bilateral aged 2-27 days and 10 unilateral aged 2-16 years) were operated upon between December 2005 and January 2009, using an endoscopic choanoplasty technique in which a laterally based mucoperiosteal flap was elevated off the posterior nasal septum and atretic plate. Endoscopic resection of bony atresia including abnormally thickened vomer and pterygoid processes was done un…

Breaking the mold: telescoping drives the evolution of more integrated and heterogeneous skulls in cetaceans.

BACKGROUND: Along with the transition to the aquatic environment, cetaceans experienced profound changes in their skeletal anatomy, especial … es involved in the telescoping process (e.g., maxilla, supraoccipital) as well as other ones (e.g., vomer) not directly affected by telescoping. Other underlying evolutionary processes (such as basicranial specializations linked with hearing/breathing adaptations) could also be responsible for the changes in the connectivity and integration of palatal b …

Timing of cleft palate closure should be based on the ratio of the area of the cleft to that of the palatal segments and not on age alone.

BACKGROUND: Retrospective and prospective serial spatiotemporal investigations were carried out primarily to determine whether the ratio of the size of the posterior cleft space relative to the palatal surface area limited laterally by the alveolar ridges can be used to select the appropriate time for surgical closure of the palatal cleft space. Two subsamples were compared to determine whether the size of the palate and velocity of palatal development in well growing cases differ from those in cases treated by vomer flap surgery. The prospective investigation asked whether presurgical orthope…

Line of Sight in Hominoids.

OBJECTIVES: It remains unclear how the realignments of the face and basicranium that characterize humans were acquired, both phylogenetically and ontogenetically. The developmentally constrained nature of the skull has been previously demonstrated in other primates using Donald H. Enlow's mammalian craniofacial architectural relationships. Here, we compare crania of our closest relatives to gain greater understanding of how and why the relationship of the face and cranial base is developmentally constrained in order to inform instances of abnormal growth and clinical intervention. STUDY DESIG

Cephalometric outcome of two types of palatoplasty in complete unilateral cleft lip and palate.

In complete unilateral cleft lip and palate (CLP), a vomerplasty is assumed to improve midfacial growth because of the reduction in scarring in the growth-sensitive areas of the palate. Our aim, therefore, was to evaluate maxillofacial morphology after a modified Langenbeck technique or a vomerplasty in children with complete unilateral CLP who were operated on by a single surgeon. As part of a one-stage closure of complete unilateral CLP done during the first year of life, the technique for repair of the hard palate repair differed between the two groups. In the modified group (n=37, mean age…

Dental arch relationship in children with complete unilateral cleft lip and palate following one-stage and three-stage surgical protocols.

The objective of this study is to compare dental arch relationship following one-stage and three-stage surgical protocols of unilateral cleft lip and palate. Dental casts of 61 children (mean age, 11.2 years; SD, 1.7), consecutively treated in one center with one-stage closure of the complete cleft at 9.2 months (SD, 2.0), were compared with a sample of 97 patients (mean age, 8.7 years; SD, 0.9), consecutively treated with a three-stage protocol including delayed hard palate closure in another center. The dental casts were assigned random numbers to blind their origin. Four raters graded denta

Psychological analysis of these 104 patients is reported: 62 patients (59.6%) answered that they inhaled cocaine to improve endurance and to feel stronger and less tired; 34 patients (32.7%) in order to enjoy themsel …

The use of an O-arm in endonasal endoscopic operations of the skull base.

BACKGROUND: Endoscopic endonasal transsphenoidal approaches are broadly used nowadays for a vast spectrum of pathologies sited in the anteri … em StealthStation S7® during the surgery, where we defined two bony anatomical landmarks, such as a vomer or the origin of an intrasphenoidal septum, in each operated patient. The tip of the navigational instrument, under endoscopic control, pointed to these landmarks and the distance between the tip and the bony structure was measured on the neuronavig …

Impact of skull base development on endonasal endoscopic surgical corridors.

OBJECT: Scarce morphometric data exist on the developing skull base as a corridor for endonasal endoscopic approaches (EEAs). Furthermore, t … working parameters are mostly noted for the extreme age groups, such as the 8.6-mm increase in nare-vomer distance (p = 0.025). The nare-sellar distance is the only parameter with significant differences based on sex. Skull base lesions induce a high degree of variance in skull base measurements, delaying development and decreasing parameter values. Sku …

Three-dimensional analysis of pharyngeal airway volume in adults with anterior position of the mandible.

INTRODUCTION: The purpose of this study was to examine whether the pharyngeal airway volume in adults with skeletal Class III malocclusion is greater than in subjects with Class I occlusion and whether the pharyngeal airway volume correlated with facial morphology. METHODS: Cone-beam computed tomography scans were obtained from 60 subjects, who were assigned to 2 groups. The skeletal Class III malocclusion group consisted of 31 subjects (16 men, 15 women) who had planned on orthodontic treatment with orthognathic surgery. The Class I malocclusion group consisted of 29 subjects (14 men, 15 wom

Osteomyelitis of the Jaw in COVID-19 Patients: A Rare Condition With a High Risk for Severe Complications.

Osteomyelitis of the jaw is an uncommon infection that arises from the flora of the oral cavity or sinuses and affects immunocompromised and polymorbid patients. Treatment includes surgical debridement and long regiments of broad-spectrum antibiotics. We present three cases of complicated jaw osteomyelitis presented with concurrent COVID-19 infection, including only two reported cases of odontogenic COVID-related osteomyelitis. The two mandibular cases were patients in their 30s with no comorbidities. The first case was an asymptomatic COVID-19-positive patient who developed an odontogenic inf

A Case of Syphilis with High Bone Arsenic Concentration from Early Modern Cemetery (Wroclaw, Poland).

Venereal syphilis is a sexually transmitted disease caused by Treponema pallidum - Gram-negative, slowly growing bacteria. The spread of the disease in the Old World was due to increased birth rate, urban population growth, migration and lack of knowledge concerning the epidemiology. In the past, the treatment was mainly symptomatic and included application of mercury compounds. The goal of the study was to present the case of advanced venereal syphilis found in early modern (16th-18thc) graveyard localized in Wroclaw, Poland. The object of the study is a cranium of a male whose age at death h
