Ụdọ olu, ma ọ bụ mpịakọta olu, nke dị na ọkwa nke nkọlọ, na-enye ohere ịkpọ ụda.

Ọnọdụ. Abụọ n'ọnụọgụ, ụdọ olu dị n'ime duct nke larynx guzobere (1). N'ime duct a, ụda olu dị ihe dịka 8mm site na nsọtụ ala nke cartilage thyroid (1). Ha na-agbatị site n'ihu ruo n'azụ, na-etolitekwa ụdị V na-atụ aka n'ihu.

• N'ihu, ụda olu na-ejikọta na cartilage thyroid nke larynx.
• N'azụ azụ, ụda olu na-ejikọta na cartilage arytenoid, na ọkwa nke usoro olu.

Structure. Ihe mejupụtara ụdọ olu a bụ ọtụtụ ihe (1):

• Akpụkpọ anụ mucous nke eriri olu bụ epithelium na chorion. Nke ikpeazụ nwere ùkwù na-akpụ ligament olu ma ọ bụ ala thyro-arytenoid ligament.
• Usoro ụda olu bụ ihe nhazi nke cartilaginous nke a na-eji edozi ligament ụda na ọkwa nke cartilage arytenoid.
• Anụ ahụ nke eriri olu bụ akwara olu, nke dị na ọkpụrụkpụ nke ụda olu, yana akwara crico-thyroid. Ihe mejupụtara ùkwù abụọ, nke ikpeazụ na-etinye aka na mmegharị mkpọtụ nke cartilages arytenoid, si otú a na-ekwe ka esemokwu nke ụdọ olu.

Ime ime. Ụdọ olu nwere ọmịiko, mmetụta uche na moto. A na-eme ntinye uche site na akwara laryngeal dị elu. Akwara olu na akwara crico-thyroid na-abanye n'ime ahụ site na akwara laryngeal na-emegharị ugboro ugboro na akwara laryngeal dị n'èzí, n'otu n'otu (1).

Ọrụ na ilo. Iji gbochie ngafe nri ma ọ bụ mmiri mmiri site na trachea na ngụgụ, epiglottis na-emechi larynx na ụda olu na-agbakọta ọnụ (2).

Ọrụ iku ume. Epiglottis na ụdọ olu na -ebufe ikuku ikuku na trachea na ngụgụ, na -ekupụ ikuku na pharynx (2).

Akụkụ nke okwu. Ụda okwu na-apụta mgbe ikuku na-ekuru na-ama ụdọ olu.

Akpịrị mgbu. N'ọtụtụ ọnọdụ, ha sitere na nje virus. N'ihe banyere laryngitis ma ọ bụ epiglottitis, ha nwere ike jikọta ya na ọrịa nje.

Laryngitis. Ọ dabara na mbufụt nke larynx, karịsịa na ụda olu. Nnukwu ma ọ bụ na-adịghị ala ala, ọ nwere ike igosipụta dị ka ụkwara na dysphonia (nsogbu ụzọ). Ọ na-akawanye njọ na ụmụaka ma nwee ike iso ya na dyspnea (ihe isi ike iku ume) (3).

Ụda olu nodule. A nodule bụ bọọlụ anụ ahụ nwere ike ịmalite n'ebe ọ bụla n'ime ahụ, karịsịa na ụdọ olu. Ndị a na-abụkarị etuto ahụ na-adịghị mma, ma ọ bụ kansa ma ọ bụrụ na nodule abụrụ ọnya.

Ọrịa cancer nke eriri olu. Ụdị ọrịa kansa a na-ejikọta ya na ọrịa kansa akpịrị (4).

Ọgwụ nje ma ọ bụ ọgwụ mgbochi mkpali. Enwere ike ịnye ọgwụ nje maka ọrịa nje. Enwere ike ịnye ọgwụ mgbochi mkpali iji belata mbufụt.

Tracheotomy. N'okwu ndị kachasị njọ, ọrụ ịwa ahụ a na-agụnye oghere na ọkwa nke larynx iji kwe ka ikuku na-agafe ma gbochie asphyxiation.

Laryngectomy. N'ọnọdụ kachasị njọ nke ọrịa kansa, enwere ike iwepụ larynx (5).

Radiotherapy. A na-ebibi mkpụrụ ndụ kansa site na ikpughe na ụzarị ọkụ (5).

Chemotherapy. Enwere ike inye ọgwụ iji gbochie mgbasa ọrịa kansa.

Laryngoscopy na-apụtaghị ìhè. Ọ na-enye gị ohere ịhụ nkọlọ na-eji obere enyo etinyere n'azụ akpịrị (6).

Direct laryngoscopy. A na-amụ nkọlọ na-eji tube siri ike ma na-agbanwe agbanwe ewebata site na imi. Ntinye aka a nwekwara ike ikwe ka ewee ihe nlele (biopsy) ma ọ bụrụ na nyocha ahụ chọrọ ya (6).

Laryngopharyngography. Enwere ike ime nyocha x-ray a nke larynx iji mechaa nyocha ahụ (6).

Ọnọdụ dị ala nke larynx na ụmụ mmadụ nke oge a ma e jiri ya tụnyere anụmanụ ndị ọzọ bụ isiokwu nke echiche banyere mmalite asụsụ. Otú ọ dị, nnyocha e mere n'oge na-adịbeghị anya na-egosi na ike ikwu okwu tọrọ nnọọ ụtọ (7).
