Olfactory function following open rhinoplasty: A 6-month follow-up study

Abstract

Background: Patients undergoing any type of nasal surgery may experience degrees of postoperative olfactory dysfunction. We sought to investigate "when" the olfactory function recovers to its preoperative levels.

Effect of Septorhinoplasty on Olfactory Function: Assessment Using the Brief Smell Identification Test

“…The authors concluded that postoperative edema and inflammation following open rhinoplasty caused a temporary reduction in olfactory function; however, function returned to the preoperative level within 6 months following surgery. Furthermore, Shemshadi et al (8) suggested that the type of nasal surgery performed could explain the difference between their findings and those of previous studies. Although some surgical procedures may cause direct trauma to the olfactory neuroepithelium or distort intranasal anatomy, the direct effects of procedures such as open rhinoplasty are minimal.…”

“…Although some surgical procedures may cause direct trauma to the olfactory neuroepithelium or distort intranasal anatomy, the direct effects of procedures such as open rhinoplasty are minimal. The indirect effects of nasal surgery are thought to arise from pharmacological agents or mucosal edema; thus, all types of nasal surgery, including open rhinoplasty, can potentially cause nasal or olfactory nerve damage that indirectly affects olfaction (8). Although surgeons do not agree whether olfactory function will recover after surgery, our patient who complained of anosmia at week 4 post-surgery regained his sense of smell by week 12.…”

“…The few studies that have assessed olfactory function following SRP have reported inconsistent findings ranging from decreased to unchanged and improved sense of smell. The most common cause of decreased olfactory function following surgery is mucosal damage resulting from trauma, edema, or inflammation in the olfactory region (8,9).…”

The outcome of septorhinoplasty surgery on olfactory function

“…In a cohort of 40 patients undergoing aesthetic rhinoplasty, there was significant decrease in sense of smell as tested by the ‘Smell Identification Test’ in the post‐operative period. At 6 months post‐operatively, the sense of smell had returned to close to the pre‐operative level (although one patient had improved) …”

Functional consequences of rhinoplasty (A review of literature)

“…Н. Shamshadi и соавт. [31] обследовали 40 пациентов до и после от крытой ринопластики и выявили, что на 1й после операционной неделе в 87,5% случаев выявлена аносмия, на 6й послеоперационной неделе у 85% больных отмечалась гипосмия от легкой до средней степени тяжести и к 6му послеоперационному ме сяцу значения обонятельной функции были тожде ственны с дооперационными.…”
