Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
Equipment Required

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Chronic Pharyngitis

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Tonsillitis I: Introduction

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Summary

Superior nasal septal deviation is linked to dacryocystitis incidence and re-stenosis after dacryocystorhinostomy. This study highlights septal deviation as a key factor in tear duct obstruction and surgical outcomes.

Ophthalmology
Otorhinolaryngology
Surgical Anatomy

Background:

Dacryocystitis (DC) results from nasolacrimal duct obstruction, causing tear sac overflow, epiphora, and inflammation.
Dacryocystorhinostomy (DCR), external or endoscopic, creates a tear pathway bypass from the lacrimal sac to the nose.
The role of superior nasal septal deviation in DC incidence and DCR outcomes requires further investigation.

Purpose of the Study:

To investigate superior nasal septal deviation as a potential contributing factor in the incidence of dacryocystitis.
To evaluate the influence of superior nasal septal deviation on the success and complications of dacryocystorhinostomy.

Main Methods:

Retrospective study of 36 patients surgically treated for chronic dacryocystitis between September 2019 and September 2024.
Analysis of patient demographics, nasal septal deviation, concha bullosa presence, surgical approach (endoscopic vs. external Toti), and intraoperative cultures.
Assessment of post-operative re-stenosis rates.

Main Results:

Superior nasal septal deviation was present in all 36 patients (100%).
Endoscopic DCR was performed in 88.9% of cases; septoplasty was not required in any endoscopic procedures.
Re-stenosis occurred in 13.9% of patients; intraoperative cultures were positive in 25% of cases.

Conclusions:

Superior nasal septal deviation appears to be a significant factor in both the development of dacryocystitis and the occurrence of re-stenosis post-DCR.
Further research is needed to identify specific nasal septum deviations associated with higher risks and to clarify the role of septoplasty in DCR outcomes.
