Cranial Bones: Lateral View01:27

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...
Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
Psychosurgery01:30

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...
Suctioning the Nasopharyngeal Airway01:29

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.

Summary

Septoplasty surgery improved nasal airflow and olfactory function, leading to enhanced cognitive abilities like attention and processing speed. Further research is needed to determine if these cognitive gains stem from better breathing or improved sense of smell.

Endoscopic Septoplasty with Limited Two-line Resection: Minimally Invasive Surgery for Septal Deviation

Published on: June 20, 2018

Area of Science:

  • Otolaryngology
  • Neuroscience
  • Cognitive Science

Background:

  • Septal deviation often leads to nasal obstruction, impacting quality of life.
  • Nasal obstruction may affect olfactory function and potentially cognitive performance.
  • Septoplasty aims to correct septal deviation and improve nasal airflow.

Purpose of the Study:

  • To investigate the effects of septoplasty on cognitive functions including selective attention, information processing speed, and response inhibition.
  • To explore factors associated with these cognitive changes after septoplasty.
  • To assess the impact of septoplasty on nasal airflow and olfactory function.

Main Methods:

  • Seventy-three patients undergoing septoplasty for septal deviation were evaluated.
  • Assessments included nasal obstruction symptom evaluation (NOSE) score, peak nasal inspiratory flow (PNIF), Sniffin' Sticks (SS) test, retronasal olfactory threshold test (ROTT), and Stroop test.
  • Statistical analyses included Wilcoxon signed-rank, McNemar's, Spearman's correlation, linear, and logistic regression.

Main Results:

  • Septoplasty significantly improved NOSE scores, PNIF, SS discrimination and TDI, ROTT, and Stroop A-D scores.
  • Significant correlations were found between olfactory function (SS TDI, ROTT) and cognitive tests (Stroop).
  • Improvements in nasal airflow and olfaction did not directly correlate with postoperative cognitive test improvements.

Conclusions:

  • Septoplasty enhances nasal airflow, olfactory function, and cognitive abilities such as selective attention, information processing speed, and response inhibition.
  • The precise mechanism linking cognitive improvements to olfactory function or nasal obstruction relief remains unclear.
  • Septoplasty offers a potential therapeutic avenue for individuals experiencing cognitive deficits associated with nasal obstruction.
